Roles of cytotoxic lymphocytes and MIC/LILR families in pathophysiology of Takayasu arteritis
Authors: Yoshifuji Hajime , Terao Chikashi
Published: June 2020

Takayasu arteritis (TAK) affects the aorta and its primary branches, mainly in young women. In its advanced stages, it can cause severe complications, such as cerebral infarction, impaired vision, and valvular heart diseases. In the aortic tissue of TAK, there is increased infiltration of cytotoxic lymphocytes, such as natural killer (NK) cells and CD8+T cells, and enhanced expression of accessory molecules, such as major histocompatibility complex (MHC) and MHC class I chain-related gene (MIC) family. Genome-wide association studies on TAK have identified susceptibility genes, such as IL-12p40, MICA, MICB, leukocyte immunoglobulin-like receptor A3 (LILRA3), and LILRB3. Other studies have also shown their involvement in the pathophysiology of TAK. In addition, we reported the importance of NK cells by enhancer enrichment analysis. These results suggest that the gene polymorphisms that potentially upregulate the expression of cytokines and accessory molecules, which contribute to the activation of cytotoxic lymphocytes, are associated with the development of TAK. Based on these results, new molecular targeted therapies look promising.
Management of the aphid, Myzus persicae (Sulzer) and the whitefly, Bemisia tabaci (Gennadius), using biorational on capsicum under protected cultivation in India
Authors: Singh Harshdeep , Joshi Neelam
Published: June 2020

The peach aphid, Myzus persicae (Hemiptera: Aphididae) and silver leaf whitefly, Bemisia tabaci (Hemiptera: Aleyrodidae) are the major pests of capsicum under protected cultivation. The entomopathogenic fungi (EPF) are environmentally safe than the chemical pesticides. In the present study, different EPF formulations, Beauveria bassiana Balsamo (Vuillemin), Lecanicillium lecanii (Zimmerman) Viegas, Metarhizium anisopliae (Metschnikoff) Sorokin, were evaluated along with Azadirachtin 1% for the management of the aphid and the whitefly on capsicum under protected conditions. Result showed that talc formulation of L. lecanii MTCC 956 at 10 and 12 g/l caused 60.5 and 61.6% population reduction for aphid and 60.0 and 61.6% population reduction for whitefly, whereas Azadirachtin 1% at 4 and 5 ml/l caused 71.2 and 74.7% population reduction for aphid and 68.5 and 71.0% population reduction for whitefly after 3rd spray, respectively and were effective in reducing aphid and whitefly populations on capsicum recommending its organic production under protected cultivation and could be a part of integrated pest management program.

Authors: Benzohra Omar , Ech-Charqaouy Sidi Salah , Fraija Fouzia , Saifaoui Dennoun
Published: June 2020

The production of electrical energy has always been a subject of debate to fight against climate change and preserve natural resources. Several countries, including Morocco, have proposed ambitious policies to develop renewable energy sources of production in the short and medium term. The major problem of renewable sources production is their intermittent nature. Using storage units, particularly PETS’ and molten salt technologies, will increase the penetration rate of renewable energies. The balance between production and consumption will optimize production, and it represents an important aspect of smart grids. In this article, an electrical energy consumption prediction was developed for the period 2019-2025, and optimization of the renewable energies injected within the grid was made by introducing the algorithm used. The results show that the use of storage units will increase the rate of renewable energies integration to 47.189% of the total installed capacity.

Induced polarization effect on grounded-wire transient electromagnetic data from transverse electric and magnetic fields
Authors: Zhou Nan-Nan , Kangxin Lei , Xue Guoqiang , Chen Wen
Published: June 2020

Transient electromagnetic (TEM) data can be seriously distorted by induced polarization (IP) phenomena when a polarizable body is present. The TEM field generated by a grounded-wire source contains transverse electric (TE) and transverse magnetic (TM) modes. The IP effect is most commonly studied with the TEM total field, rather than considering the difference between TE and TM fields. To investigate the effect of IP phenomena on the TE and TM fields, we have performed a detailed analysis on IP-distorted TEM data based on numerical and field examples. We first compare the IP effect on the TE and TM fields when polarizable bodies with different polarizable parameters are present. The TM field is more severely affected by the IP effect than the TE field. Compared to a single grounded-wire source, a double-line grounded-wire source can generate a larger TM field in the horizontal electric field. We compare the IP effect on TEM data from single- and double-line grounded-wire TEM configurations, and find that the data from the double-line configuration have a higher TM/TE ratio and are more severely affected by IP phenomena than in the single-line case. Thus, it would be easier to identify and extract the IP response from field data acquired with a double-line grounded-wire source configuration. These results have been verified by a field survey of the Kalatongke copper-nickel ore district, which has predominantly layered geology, in Xinjiang, China.
Deep convolutional neural network and sparse least-squares migration
Authors: Liu Zhaolun , Chen Yuqing , Schuster Gerard
Published: June 2020

We have recast the forward pass of a multilayered convolutional neural network (CNN) as the solution to the problem of sparse least-squares migration (LSM). The CNN filters and feature maps are shown to be analogous, but not equivalent, to the migration Green’s functions and the quasi-reflectivity distribution, respectively. This provides a physical interpretation of the filters and feature maps in deep CNN in terms of the operators for seismic imaging. Motivated by the connection between sparse LSM and CNN, we adopt the neural network version of sparse LSM. Unlike the standard LSM method that finds the optimal reflectivity image, neural network LSM (NNLSM) finds the optimal quasi-reflectivity image and the quasi-migration Green’s functions. These quasi-migration Green’s functions are also denoted as the convolutional filters in a CNN and are similar to migration Green’s functions. The advantage of NNLSM over standard LSM is that its computational cost is significantly less and it can be used for denoising coherent and incoherent noise in migration images. Its disadvantage is that the NNLSM quasi-reflectivity image is only an approximation to the actual reflectivity distribution. However, the quasi-reflectivity image can be used as an attribute image for high-resolution delineation of geologic bodies.
Ground-roll attenuation using generative adversarial networks
Authors: Yuan Yijun , Si Xu , Zheng Yue
Published: June 2020

Ground roll is a persistent problem in land seismic data. This type of coherent noise often contaminates seismic signals and severely reduces the signal-to-noise ratio of seismic data. A variety of methods for addressing ground-roll attenuation have been developed. However, existing methods are limited, especially when using real land seismic data. For example, when ground roll and reflections overlap in the time or frequency domains, traditional methods cannot completely separate them and they often distort the signals during the suppression process. We have developed a generative adversarial network (GAN) to attenuate ground roll in seismic data. Unlike traditional methods for ground-roll attenuation dependent on various filters, the GAN method is based on a large training data set that includes pairs of data with and without ground roll. After training the neural network with the training data, the network can identify and filter out any noise in the data. To fulfill this purpose, the proposed method uses a generator and a discriminator. Through network training, the generator learns to create the data that can fool the discriminator, and the discriminator can then distinguish between the data produced by the generator and the training data. As a result of the competition between generators and discriminators, generators produce better images whereas discriminators accurately recognize targets. Tests on synthetic and real land seismic data show that the proposed method effectively reveals reﬂections masked by the ground roll and obtains better results in the attenuation of ground roll and in the preservation of signals compared to the three other methods.
Noise estimation in vector magnetic data derived from airborne vector magnetic system
Authors: Xie Rukuan , Xiong Shengqing , Duan Shuling , Wang Jinlong , Wang Ping , Luo Yao , Liu Haojun , Fan Zhengguo
Published: June 2020

The accuracy of the airborne vector magnetic (VM) survey mainly depends on the attitude measurement precision of the aircraft. An orientation change of 0.001° can produce an error of approximately 1 nT in VM components for a geomagnetic field of 50,000 nT. Therefore, noise estimation or accurate understanding of noise characteristics of measured airborne VM data plays an important role in geophysical applications. A new airborne VM system with high-precision attitude measurement (0.003°–0.007° root-mean square [rms]) for geophysical prospecting was developed. We have analyzed the results from test flights, compared the difference between measured and calculated VM data, and we developed two methods to estimate the noise in VM data derived from the new system, which include (1) VM noise, that is, the rms error of the difference between the total magnetic intensity calculated from the measured VM data and measured by the scalar sensor, to mainly estimate the error of calibration and compensation, and (2) rms error of the difference between the data from repeat flight lines, to mainly estimate the error of multiple measurements. The noise estimation results of the two methods based on data from test flights in the Qixin area of the East Tianshan Mountains in China indicate that the new system has high accuracy: VM noise is 2.32 nT; the error of the repeat flight lines is 4.86, 6.08, and 2.80 nT for the [Formula: see text], [Formula: see text], and [Formula: see text] components, respectively.
Eco-media Events in China
Authors: Litzinger Ralph , Yang Fan
Published: June 2020

This article brings together recent writing on eco-media, media materialism, and racialized Otherness to rethink the place of China and Asia in debates about the Anthropocene. We begin by examining the nonwhite postapocalyptic futures imagined in Bong Joon-ho’s sci-fi film Snowpiercer and argue that the film problematizes a persistent Western-centric bias in both the environmental humanities and the literature on media materialism. Inspired by the metaphoric power of Kronon, the industrial-waste-turned-explosive in Snowpiercer, we theorize the instantaneously mediated and circulated chemical dust explosions in Kunshan and Tianjin in 2014–15 as eco-media events—that is, spectacular and ephemeral moments in which the material processes of digital production link the old forms of resource extraction with our new lives of electronic gadgetry and media tool dependency. Writing against the discourse of Yellow Eco-peril, which depicts such events (in both academic and journalistic writings) through a racialized Eco-Otherness, we offer a counter-politics to reconnect mainland China to the very systems of globalized production and consumption—the deep earth mining, the slow violence of black lung disease, the factory work, the digital consumption practices—that have propelled and intensified the country’s stupendous development as well as its ecological challenges. We find new work on eco-media and media materialism most productive, as it sheds light on three closely intertwined dimensions of eco-media events: time, body, and matter. Probing the deep entanglements between the human and the nonhuman, a critical engagement with these events presents new possibilities to think anew environmental humanities in China, across Asia, and globally.
Chemosociality in Multispecies Worlds
Authors: Kirksey Eben
Published: June 2020

Chemosocial communities have formed in Sydney, Australia, as a result of encounters with industrial pollution. If biosociality involves social relationships that emerge from biological conditions, then chemosociality involves altered, attenuated, or augmented relationships that emerge with chemical exposures. Some social groups have coalesced around place-based political action, while other chemosocial associations have proved to be ephemeral, evanescent, and conditional. Building on earlier work by multispecies ethnographers who have studied social relationships among humans and animals, this article follows chemicals into more-than-human realms. Fragile multispecies worlds have emerged in a complex landscape shaped by chemical weapons industries, municipal landfills, government remediation programs, real estate speculation, and a multitude of chemical and biological agents. Legacy dumping grounds in the Sydney Olympic Park have become habitat for the green and golden bell frog, an endangered species. While the normal world order of this frog has been lost with the spread of a deadly fungal disease, toxic chemicals have enabled the continuation of its social life. Temporary spaces of immunity have emerged where life is protected and threats are negated by poisonous compounds that double as a cure.
Multicultural Wilderness
Authors: Fisher Colin
Published: June 2020

Wilderness parks in the United States are often described as landscapes of leisure for affluent white nature tourists. This article challenges that interpretation by exploring visitation to the Cook County Forest Preserves and the Indiana Dunes State Park, two Chicago-area wilderness parks that during the early twentieth century attracted far more visitors than all of the national parks combined. The author argues that if we turn our gaze from rarefied and far less-visited parks such as Yosemite and Yellowstone to the wilderness parks created just outside of major metropolitan centers, we can clearly see that early-twentieth-century wilderness landscapes attracted a far more cosmopolitan audience than commonly assumed. Moreover, the author shows that marginalized Chicagoans were not simply passive consumers of wilderness. Drawing on theorists and historians of mass-culture reception, the author makes the case that new immigrants, children of the foreign-born, African Americans, and industrial workers appropriated these Chicago wilderness parks in much the same way that they borrowed and creatively rewrote Jazz-Age mass-culture entertainment such as Hollywood films. Far from places that Americanized immigrants and neutralized class tension, Chicago-area wilderness parks became important sites for the production and reproduction of subaltern national, ethnic, and working-class communities.
Submerged Bodies
Authors: DeLoughrey Elizabeth , Flores Tatiana
Published: June 2020

Recent scholarship in the blue humanities, or critical ocean studies, has turned to the mutable relationship between human bodies and the ocean, shifting from depictions of a seascape across which human bodies attain agency to considering the experience and representability of sea ontologies, wet matter, and transcorporeal engagements with the more-than-human world. This work generally focuses on a universalized ocean (as nonhuman nature) rather than a geographically and culturally specific place (as history). The authors’ work turns the visual focus from the surface to the depths, engaging with the Caribbean Sea and contemporary artists who depict a gendered oceanic intimacy and aesthetics of diffraction and submergence. Building upon the 2017 exhibition Relational Undercurrents: Contemporary Art of the Caribbean Archipelago, curated by Tatiana Flores, this article expands the conversation from the archipelagic to the submarine, engaging “tidalectic” representations of underwater bodies through ontologies and aesthetics of diffraction. The authors consider the work of artists Tony Capellán, Jean-Ulrick Désert, María Magdalena Campos-Pons, Nadia Huggins, and David Gumbs.
Toward a Relational Materiality of Soils
Authors: Krzywoszynska Anna , Marchesi Greta
Published: June 2020

As environmental matters, soils have been an object of inquiry primarily for the natural sciences, with social scientists and environmental humanities scholars occupied with the surface dramas of territory and its products. The invisibility of soils in much of public and intellectual life speaks not only to the literal invisibility of their subterranean elements but also to their taken-for-granted effectiveness as the material infrastructure of societies. Today’s crisis of soil ecosystems calls for an urgent examination and improvement of human-soil relations. This is both an intellectual and a practical project. The authors believe that a crucial first step toward more just and sustainable human-soil relations is a critical reflection around soil knowledge practices and their onto-political effects. In this introduction, they open the field for such reflection by denaturalizing the category soil, discussing its complex materialities, its multiple scales, and the diversity of existing soil ontologies and epistemologies. In so doing they argue for a relational materiality approach to the study of soils. The authors place this relational materiality approach within a practical, political, and ethical project of re-embedding societies in soils and lands. Finally, they indicate emerging arenas of inquiry where a relational materiality approach to soils is needed.
Justus von Liebig Makes the World
Authors: Marchesi Greta
Published: June 2020

Just as capitalism’s exchange of commodities between disparate locations requires a singular referent of value, so does the movement of ideas and practices necessitate consolidations of meaning through complex fields of people, landscapes, and things. Introducing key innovations in agricultural and chemical science, Justus von Liebig’s chemical model of soil fertility involved a profound reenvisioning of organic development, distilling complex processes to a series of chemical relationships easily recognized in any geographic context. Drawing on Henri Lefebvre’s (1984) arguments about the production of abstract space, this article argues that Liebig’s assessment of nutrient extraction was essential to a broader midcentury reconsideration and reorganization of capitalist agricultural production, an example of what world ecologist Jason Moore calls an “organizational revolution,” allowing global capitalism to overcome past limits and thus move through systemic crises.
Presenting Endangerment
Authors: Baynham-Herd Zachary
Published: June 2020

Endangered species are not simply revealed but are presented. This process of presentation is shaped by conservation discourses that reflect how actors understand, categorize, and imagine nonhuman life. Such discourses combine to produce narratives of endangerment, which influence policy and conservation efforts. This article examines how particular physical, epistemic, and cultural geographies mediate the production of conservation discourses and narratives of endangerment. It explores an anomalous case in which the endangered species presented never physically existed: the story of the conservationist Sir Peter Scott and the Loch Ness phenomena (Nessie). By reinterpreting Scott’s correspondence covering the Loch Ness Phenomena Investigation Bureau in the 1960s and 1970s, this article outlines the discursive production of Nessie as, first, a scientifically recognized species, and, second, an endangered creature warranting protection. Nessie’s nonphysical existence is argued to reveal the ways in which living things are ancillary to the discourses through which they become protected. Specifically, this article demonstrates how Nessie’s proposed endangerment was produced through ostensibly scientific discourses accessed through particular social networks, understandings, values, procedures, and imagery. In doing so it highlights the other physical and human geographies, including nationalism, landscape, media, and technology, that shaped this and likely other presentations of endangerment.
A gum arabic assisted sustainable drug delivery system for adult Drosophila

Published: June 2020

Large-scale compound screenings in adult flies is hampered by the lack of continuous drug delivery systems and poor solubility of numerous compounds. Here we found that gum Arabic (Acacia/Senegal gum), a widely used stabilizer, can also emulsify lipophilic compounds and profoundly increase their accessibility to target tissues in Drosophila and mice. We further developed a gum Arabic-based drug delivery system, wherein the drug was grinded in gum Arabic and emulsified in liquid food fed to flies by siphoning through a U-shape glass capillary. This system did not affect food intake nor cell viability. Since drugs were continuously delivered by siphoning, minimal compound waste and less frequent food changes make this system ideal for large scale long-term screenings. In our pilot screening for antitumor drugs in the NCI DTP library, we used a Drosophila model of colorectal cancer and identified two drugs that are especially hydrophobic and were not identified in previous screenings. Our data demonstrated that gum Arabic facilitates drug delivery in animal models and the system is suitable for long-term high-throughput drug screening in Drosophila. This system would accelerate drug discovery for chronic and cognitive conditions.
A fully automated deep learning pipeline for high-throughput colony segmentation and classification
Authors: Carl Sarah H. , Duempelmann Lea , Shimada Yukiko , Bühler Marc
Published: June 2020

Adenine auxotrophy is a commonly used non-selective genetic marker in yeast research. It allows investigators to easily visualize and quantify various genetic and epigenetic events by simply reading out colony color. However, manual counting of large numbers of colonies is extremely time-consuming, difficult to reproduce and possibly inaccurate. Using cutting-edge neural networks, we have developed a fully automated pipeline for colony segmentation and classification, which speeds up white/red colony quantification 100-fold over manual counting by an experienced researcher. Our approach uses readily available training data and can be smoothly integrated into existing protocols, vastly speeding up screening assays and increasing the statistical power of experiments that employ adenine auxotrophy.
Promoting Physical Activity among Underserved Populations

Published: June 2020

Underserved populations, including racial/ethnic minorities, individuals with low socioeconomic status, and individuals with physical disabilities, are less likely to engage in sufficient moderate to vigorous physical activity (MVPA) and are thus at increased risk of morbidity and mortality. These populations face unique challenges to engaging in MVPA. Learning how to overcome these challenges is a necessary first step in achieving health equity through health promotion research. In this review of the literature, we discuss issues and strategies that have been used to promote MVPA among individuals from underserved populations, focusing on recruitment, intervention delivery, and the use of technology in interventions. Physical activity promotion research among these vulnerable populations is scarce. Nevertheless, there is preliminary evidence of efficacy in the use of certain recruitment and intervention strategies including tailoring, cultural adaptation, incorporation of new technologies, and multilevel and community-based approaches for physical activity promotion among different underserved populations.
Nutrition and Supplements for Elite Open-Weight Rowing
Authors: Boegman Susan , Dziedzic Christine E.
Published: June 2020

Competitive rowing events are raced over 2,000 m requiring athletes to have highly developed aerobic and anaerobic systems. Elite rowers therefore undertake training sessions focused on lactate tolerance, strength and power as well as aerobic and anaerobic capacity development, that can amount to a 24-h training week. The training stimuli and consequent metabolic demands of each session in a rowing training program differ depending on type, length, and intensity. Nutrition guidelines for endurance- and power-based sports should be drawn upon; however, individualized and flexible nutrition plans are critical to successfully meet the daily, weekly, and cyclic nutrient requirements of a rower. This review will provide an overview of key nutritional strategies to optimize training and enhance adaptation, and briefly discuss supplement strategies that may support health and enhance performance in elite rowing.
Recent Developments in the Use of Sodium Bicarbonate as an Ergogenic Aid
Authors: McNaughton Lars R. , Gough Lewis , Deb Sanjoy , Bentley David , Sparks S. Andy
Published: June 2020

This review examines the current status of sodium bicarbonate as an ergogenic aid. It builds on previous reviews in the area. Current research would suggest that as an ergogenic aid, a 300 mg·kg−1 dose of NaHCO3 can improve high-intensity exercise, within a range of exercise modalities, such as a single bout of supramaximal exercise, high-intensity intermittent activity, and skill-based sports. In particular, these benefits seem to be present to a greater extent within trained individuals. Despite this, there appears to exist a high intraindividual variability in response to NaHCO3, and therefore, the ergogenic benefits may not be induced during every exercise bout. Current thinking also suggests that athletes need to individualize their ingestion timings to maximize peak pH or blood bicarbonate to effectively maximize the performance effect, and this may allow individuals to attain the ergogenic benefits of NaHCO3 more consistently.
Measuring Time Preferences

Published: June 2020

We review research that measures time preferences—i.e., preferences over intertemporal trade—offs. We distinguish between studies using financial flows, which we call “money earlier or later” (MEL) decisions, and studies that use time-dated consumption/effort. Under different structural models, we show how to translate what MEL experiments directly measure (required rates of return for financial flows) into a discount function over utils. We summarize empirical regularities found in MEL studies and the predictive power of those studies. We explain why MEL choices are driven in part by some factors that are distinct from underlying time preferences. (JEL C61, D15)
The Limits of the Commune: A Review of The Mystery of the Kibbutz
Authors: Nye John V. C.
Published: June 2020

Ran Abramitzky's book, The Mystery of the Kibbutz: Egalitarian Principles in a Capitalist World, tries to answer the questions of why the communal kibbutz worked so well in Israel's formative years and what limits its current success in modern Israel. Initial ideological commitment and the special circumstances of Israel's founding led to unusual success when combined with well-thought-out rules on behavior and entry. Over time, the commitment to socialistic income sharing has not worked so well, given modern technology and global commerce. The author links up these ideas to the broader issue of organizational structure but misses out on some opportunities to test the ideas further. (JEL D31, D63, D82, J24, P13, Q13)
Effect of different biofloc starters on ammonia, nitrate, and nitrite concentrations in the cultured tilapia Oreochromis niloticus system
Authors: Putra Iskandar , Effendi Irwan , Lukistyowati Iesje , Tang Usman M. , Fauzi Muhammad , Suharman Indra , Muchlisin Zainal A.
Published: June 2020

Background: High stocking density and intensive feeding in aquaculture systems lead to the accumulation of organic waste, which results in an increase in ammonia, nitrite, and nitrite concentrations in culture media. Biofloc is a potential technology to overcome this problem. The starter is a crucial carbon source for bacteria in the formation of biofloc. The objective of the present study aimed to explore the best starter of biofloc in a red tilapia Oreochromis niloticus culture system.

Methods: A completely randomized design with four levels of treatment was used in this study. The tested starter was (A) control treatment, biofloc without starter, (B) biofloc with molasses starter, (C) biofloc with tapioca starter, and (D) biofloc with sucrose starter. The floc was cultured in 100-L tanks with a salinity of 17 ppt. The tanks were stocked with O. niloticus with a size of 3.71±0.11 cm at a stocking density of 30 fish per tank. The fish were fed on a commercial diet two times a day at satiation for 40 days. The ammonia, nitrite, and nitrite concentrations were measured for an interval of 8 days.

Results: The study showed that the NH3-N range was 0.02–0.07 mg L−1 (mean, 0.03 ± 0.02 mg L−1), NO2-N range was 0.20–0.43 mg L−1 (mean, 0.25 ± 0.12 mg L−1), and NO3-N range was 0.90–3.20 mg L−1 (mean, 1.42 ± 1.19 mg L−1).

Conclusion: Among the starters tested, molasses was found to be the best for biofloc in tilapia culture.
SPEEDS OF SPRING WHEAT GROWTH AND DEVELOPMENT DEPENDING ON HYDROTHERMAL CONDITIONS
Authors: Poskrebysheva Marina , Ismagilov Rafael'
Published: June 2020

Studies were conducted to study the effect of air temperature and the amount of precipitation on the growth and development of spring wheat plants. Analysis and quantitative description of the dependence of the duration of interphase periods was carried out by methods of correlation and regression analysis, changes in the duration of periods by calculating the coefficient of variation. For analysis, we used the results of long-term field observations (2014–2019) over the time of the onset of phenological phases in spring wheat varieties of the mid-ripe group in the Ural steppe, as well as published data of Davlekanovskiy GSU of the Republic of Bashkortostan for 1993–2016. An increase in temperature during all periods of vegetation accelerates the growth and development of plants, an increase in rainfall, on the contrary, slows down these processes. The change in hydrothermal conditions most strongly affects the duration of tillering – heading and heading – waxy ripeness periods. The coefficient of variation of their duration is 26.9 and 28.7, respectively. With an increase in air temperature by 1°C in the range of 11.3 ... 20.50С, the tillering-heading interfacial period decreases by 0.408 days, and the ripening of spring wheat grain (at a temperature of 10.7 ... 24.2°C) is accelerated by 0.424 of the day. An increase in precipitation by 10 mm in the range of 1.0 ... 126.2 mm slows the onset of heading by 0.39 days, waxy ripeness of grain (with a total of 0 ... 131.1 mm) - by 0.40 days. Statistical models of the dependence of the duration of interphase periods of growth and development of spring wheat plants on the amount of precipitation and average daily temperature can be used to predict the calendar dates of the onset of phenological phases and the operational adjustment of technological operations to care for sowing

Published: June 2020

Este trabalho tem como finalidade contribuir para a reflexão do papel desempenhado pelos empreendedores de políticas públicas no surgimento de política de apoio à Economia Solidária (ES). A Economia Solidária foi incorporada como Política Pública em 2003, através do SENAES/MTE. A agenda política sobre a ES foi definida pela participação de três pesquisadores que atuaram como empreendedores políticos: Paul Singer, Luiz Gaiger e Marcos Arruda. Esses pesquisadores exerceram influência na alternativa implementada, atuando como empreendedores políticos. Diante desse contexto, este artigo analisa as ideias desses três pesquisadores através de revisão sistemática de seus conceitos contidos em suas produções científicas. Considera-se que essas ideias fundamentaram a coalizão de defesa da política pública de Economia Solidária. Conclui-se que os três empreendedores políticos contribuíram cada um com perspectivas distintas. A partir da análise das suas ideias, considera-se que a Economia Solidária tem por vocação combinar uma dimensão comunitária (mais tradicional) com uma dimensão pública (mais moderna) na sua ação. Desta forma, existem pontos em comum entre as ideias desses autores, englobando não apenas aspectos mercantis, mas também os sociais e políticos, que se incorporaram na Política Nacional de Economia Solidária.
Diagnosis of the cat with early chronic kidney disease
Authors: Groves Ellie
Published: June 2020

Chronic kidney disease (CKD) is a highly prevalent disease and common cause of morbidity and mortality in older cats. Early diagnosis and management of CKD is thought to be able to slow disease progression and impact positively on quality of life and longevity. Dietary management with a therapeutic renal diet is regarded as the mainstay of treatment for feline CKD from International Renal Interest Society stage 2 onwards. However, since the advent of markers such as symmetric dimethylarginine that have enabled clinicians to detect non-azotaemic CKD, there has been growing debate about how to best manage these patients. At this stage there are a limited number of studies investigating this. This article covers the current diagnostics used to identify renal disease. A second article looks at current understanding of therapeutic strategies and the impact this can have on progression of the disease, focusing on dietary management.
Gain without pain: beyond sport effortless exercise solutions
Authors: Sofra Xanya
Published: June 2020

Ageing is associated with decreased metabolism, increased toxicity, decreased skeletal muscle mass (SMM) and increased visceral fat deposits that compromise the normal functioning of vital organs such as the liver, pancreas and intestines, increasing the risk of a number of health problems, including type 2 diabetes, coronary heart disease, hypertension and non-alcoholic fatty liver. Visceral adipose tissue holds large amounts of toxins that alter thyroid hormone metabolism, lowering resting metabolic rate (RMR). Strenuous physical exercise can reach these deeper visceral adipose tissue layers. However, excessive exercise is necessary to reduce visceral adipose tissue elevates cortisol while decreasing testosterone. The hormonal imbalance resulting from this inverse cortisol/testosterone relationship ultimately leads to weight gain, despite all the efforts invested in physical activity. On the other hand, lack of exercise allows for accumulation of toxicity and increased vulnerability to chronic physical disorders. Energy-based technologies report successful results in reducing subcutaneous fat layers; however, data is not currently available about methods that can reduce deeper visceral adipose tissue and relieve the system from visceral fat cells stuffed with excess triglycerides. In this study, we examined hormone and cholesterol fluctuations in the blood tests of eight subjects undergoing six 45 minutes of effortless exercise sessions with a novel London University invention. We also explored changes in their visceral adipose tissue, overall body fat mass, SMM, basic metabolic rate (BMR), waist and abdomen reduction in centimetres (cm) and overall weight loss in kilograms (kg). Subjects' results revealed a statistically significant increase in triiodothyronine (Free T3), accompanied by a significant decrease in the very low-density lipoprotein (VLDL) and triglycerides. Cortisol did not show statistically significant fluctuations. There was a statistically significant decrease in visceral adipose tissue and overall body fat mass and a statistically significant increase in SMM. Waist and abdomen cm loss, and weight loss in kgs were statistically significant, demonstrating a substantial decrease in cm and kgs in all subjects that persisted a week after the last treatment. Results of this study supported the hypothesis that this method of effortless exercise can reduce both overall body fat mass, visceral adipose tissue and VLDL, while increasing SMM and the metabolic hormone free T3, without the aid of diet or change in lifestyle.

Published: June 2020

Este artículo tiene como finalidad estudiar el arte público del barrio de El Prado en Barranquilla. Para ello se analiza el contexto urbano general de la ciudad incluyendo muestras de arte público de otras zonas urbanas de esta ciudad.El artículo se estructura como un “ejercicio de estilo” que pone en diálogo el “sentir” y el “saber”. Un sentir derivado de la experiencia vivencial sobre el territorio obtenida en tres viajes a esta ciudad, que se complementa con el saber analítico derivado del estudio de las distintas problemáticas planteadas. Es por ello que, desde el punto de vista de la lectura, se ha utilizado una diferenciación en la tipografía y en el color de la misma. La tipografía Calibri light en negro describe las sensaciones de un azotacalles, término castellano próximo al flâneur baudelairdiano pero sin su carga elitista, inmerso en territorio. La tipografía Courier en granate, contrasta la información obtenida sensorialmente con la documentación de análisis utilizada.
From the DSP Perspective: Exploring the Use of Practices That Align With Trauma-Informed Care in Organizations Serving People With Intellectual and Developmental Disabilities

Trauma-informed care (TIC) is a systemwide approach that emphasizes organizational practices based upon principles of safety, choice, collaboration, empowerment, and trustworthiness. It is intended to influence an entire organization, with implications for clients and the workforce. The present study explored the extent to which IDD organizations utilize practices that align with TIC with their DSP workforce. Through an online survey, 380 DSPs (84% women; 82% white) responded to a trauma-informed organizational culture measure. Results demonstrated variability across items and significant differences between TIC principles with safety most strongly scored, and collaboration least strongly scored. Perception of organizational practices differed by ethnicity, with non-white DSPs having more favorable responses. Current practices with DSPs align with TIC, however, increased attention through explicit trauma-informed initiatives is warranted.

People with disabilities have more health complications and higher healthcare utilization related to tobacco use than people without disabilities. Yet, they are less likely to use tobacco cessation resources. Important to meaningful and lasting health behavior change are relationships developed in the home, workplace, and community. Some people with disabilities rely on paid and unpaid caregivers. Just like people with disabilities, paid caregivers are more likely to use tobacco, creating a unique opportunity to target smoking cessation to people with disabilities and their caregivers. Living Independent From Tobacco (LIFT), an evidence-based tobacco cessation intervention, was implemented with dyads of people with disabilities (n = 5) and their caregivers (n = 7). Qualitative analyses revealed that participants valued the dyadic approach and the opportunity to learn coping skills to help with smoking cessation. Lessons for offering inclusive health promotion interventions to people with disabilities and their caregivers are discussed.
Superconical aplanatic ovoid singlet lenses
Authors: Silva-Lora Alberto , Torres Rafael
Published: June 2020

In this work, we return to Descartes’s idea to develop a formalism to construct rigorously stigmatic singlet lenses comprising two Cartesian surfaces. Optical systems are built using a considerable number of spherical surfaces, presenting in most cases spherical aberration. Wasermann and Wolf proposed eliminating spherical aberration and minimizing third-order coma by using two adjacent aspherical surfaces. That is why, using a parametric formulation for Cartesian ovals, we propose the design of singlet lenses where the condition of rigorous stigmatism is guaranteed for each surface, and therefore, strictly speaking, in the pair of stigmatic points, the lens becomes an optical system free of spherical aberration. This formulation is unified to both refractive and reflective optical surfaces. Therefore, within the framework of the theory of rigorously stigmatic optical systems, making use of Cartesian surfaces for the construction of stigmatic ovoid singlet lenses, we achieve the same functionality of optical systems involving a set of spherical lenses. These lenses have the advantage of being formulated according to a generalized shape factor associated with the Coddington shape factor, allowing an easy classification of these stigmatic lenses. The ideal imaging is carried out by applying an exact ray-tracing method through these ovoid singlet lenses.
Detection and compensation of dispersion mismatch for frequency-domain optical coherence tomography based on A-scan’s spectrogram

Balanced dispersion between reference and sample arms is critical in frequency-domain optical coherence tomography (FD-OCT) to perform imaging with the optimal axial resolution, and the spectroscopic analysis of each voxel in FD-OCT can provide the metric of the spectrogram. Here we revisited dispersion mismatch in the spectrogram view using the spectroscopic analysis of voxels in FD-OCT and uncovered that the dispersion mismatch disturbs the A-scan’s spectrogram and reshapes the depth-resolved spectra in the spectrogram. Based on this spectroscopic effect of dispersion mismatch on A-scan’s spectrogram, we proposed a numerical method to detect dispersion mismatch and perform dispersion compensation for FD-OCT. The proposed method can visually and quantitatively detect and compensate for dispersion mismatch in FD-OCT, with visualization, high sensitivity, and independence from sample structures. Experimental results of tape and mouse eye suggest that this technique can be an effective method for the detection and compensation of dispersion mismatch in FD-OCT.

In this paper, a quasi-simultaneous multi-focus imaging technique named simulfocus imaging is reported. This technique was developed for measuring an entire object distributed in the depth direction beyond the depth of field (DOF) with high resolution in a single shot. Simulfocus imaging can acquire multiple focal planes in one shot by synchronizing a tunable acoustic gradient index (TAG) lens and a lock-in pixel image sensor. The TAG lens is a tunable-focus lens whose focal position can be changed at a high speed of several tens to several hundreds of kilohertz. The lock-in pixel image sensor is a special image sensor that can execute multiple exposures at an arbitrary timing during a single shooting. The sensor includes a number of photoelectron storage units in each pixel, and the units where the photoelectrons generated by each exposure are stored can be freely selected. Since an image can be acquired for a single storage unit, and the lock-in pixel image sensor has a number of storage units, the lock-in pixel image sensor can acquire multiple images in one shot. By assigning a specific exposure timing to each unit and synchronizing the exposure timing with the focus fluctuation of the TAG lens, it is possible to simultaneously acquire images in different focal planes. To evaluate the system, we conducted experiments to show the effectiveness of simulfocus imaging in microscope and telescope configurations. From the experimental results, it was confirmed that simulfocus was effective in both configurations.
Fourier propagation tool for aberration analysis and a point spread function calculation of systems with curved focal planes
Authors: Cain Stephen C.
Published: June 2020

This paper describes a new Fourier propagator for computing the impulse response of an optical system with a curved focal plane array, while including terms ignored in Fresnel and Fraunhofer calculations. The propagator includes a Rayleigh-Sommerfeld diffraction formula calculation from a distant point through the optical system to its image point predicted by geometric optics on a spherical surface. The propagator then approximates the neighboring field points via the traditional binomial approximation of the Taylor series expansion around that field point. This technique results in a propagator that combines the speed of a Fourier transform operation with the accuracy of the Rayleigh-Sommerfeld diffraction formula calculation and extends Fourier optics to cases where the receiver plane is a curved surface. Bounds on the phase error introduced by the approximations are derived, which show it should be more widely applicable than traditional Fresnel propagators. Guidance on how to sample the pupil and detector planes of a simulated imaging system is provided. This report concludes by showing examples of the diffraction patterns computed by the new technique compared to those computed using the Rayleigh-Sommerfeld technique in order to demonstrate the utility of the propagator.

Lesioak oso ohikoak dira gizonezkoen goi-mailako futbol taldeetan, eta jokalarien garapenean eta osasunean ondorio negatiboak dituzte. Hori dela eta, futbolarien lesioetan eragina izan dezaketen arrisku-faktoreak identifikatzea ezinbestekoa da. Azken urteotan egindako ikerketen arabera, hazkundeak eta heltzeak lesioen agerpenarekin erlazioa dutela aztertu arren, eragina ez dago guztiz argi eta kontraesanak daude. Lan honetan, hazkundearen eta heltzearen kontzeptu nagusiak laburbildu eta horien eta lesioen arteko harreman posibleak azaltzen dira.
