Approximate Solution Technique for Singular Fredholm Integral Equations of the First Kind with Oscillatory Kernels
Authors: Nfor Vivian Ndfutu , Okecka George Emese 
Published: July 2019

An efficient quadrature formula was developed for evaluating numerically certain singular Fredholm integral equations of the first kind with oscillatory trigonometric kernels. The method is based on the Lagrange interpolation formula and the orthogonal polynomial considered are the Legendre polynomials whose zeros served as interpolation nodes. A test example was provided for the verification and validation of the rule developed. The results showed the convergence of the solution and can be improved by increasing n.

Organic farming takes up more and more areas in agricultural production. It is based on the principles of preserving human and animal health and maintaining the balance in agrobiocenosis and therefore prohibits the use of a majority of water-soluble mineral fertilizers and phytopharmaceuticals of chemical origin (except those from the list of allowed products). In ecological farming of plums, optimization of fertilization is very important, which must comply with ecological principles and regulations which included fertilization with a relatively narrow range of allowed organic fertilizers (manure, compost, manure, slurry, peat, guano, sawdust) and mineral additives (calcium carbonate, crude phosphates, basic slag, raw potassium salt, potassium sulphate, gypsum, wood ash, calcium chloride, sodium chloride, etc.).
Nutrition methods in organic plum production are different from nutrition in conventional production, primarily due to a limited selection of available fertilizers, and the most important difference is the inability to use water-soluble individual and complex fertilizers. It is precisely for this reason that in organic agriculture, the emphasis on maintaining humidity, optimum pH and soil moisture is considerably more important than necessary prerequisites for sufficient availability of nutrients in the soil.

Authors: Souza Daniela Vieira de , Carrapeiro Mariana De Magalhães 
Published: July 2019

<p>Introdução: o cálcio está sendo associado à participação no metabolismo energético e na composição corporal. Objetivo: com base nas evidências científicas, o estudo visou analisar a influência do cálcio de origem elementar e láctea sobre o peso e a gordura corporal, e verificar qual fonte de cálcio proporciona melhores resultados na composição corporal. Metodologia: realizou-se uma revisão da literatura entre 2000 e 2016 utilizando os seguintes descritores: cálcio, obesidade, produtos lácteos e suplementação e seus correspondentes em espanhol e inglês, bem como os cruzamentos desses descritores nas três línguas. A revisão foi estruturada em quatro tópicos: a obesidade e seus fatores; efeito da suplementação de cálcio elementar sobre o peso e a gordura corporal; efeito do cálcio de origem láctea sobre o peso e a gordura corporal; mecanismos fisiológicos entre cálcio e composição corporal. Resultados: verificou-se maiores efeitos do cálcio oriundo dos laticínios sobre o peso e a gordura corporal quando comparado a suplementação de cálcio elementar. Estes resultados podem estar associados a presença de compostos bioativos em leites e derivados que atuam de forma independente ou sinérgica com a supressão da 1,25-di-hidroxi vitamina D<sub>3</sub>. O mecanismo mais consistente sobre a influência do cálcio na composição corporal associa a maior ingestão deste à diminuição da secreção dos hormônios calciotrópicos, possibilitando assim, maior lipólise e menor lipogênese de novo. Conclusão: os estudos científicos apontam para efeitos positivos do cálcio, especialmente de origem láctea sobre o peso e a composição corporal, principalmente quando associado à restrição calórica. </p>

The association between effective workplace communication with superiors and lower psychological distress among workers in the evacuation area after the Fukushima Daiichi Nuclear Power Plant accident
Authors: Orui Masatsugu , Yasumura Seiji 
Published: July 2019

Abstract

Objectives
Well-managed workplace communication may promote well-mental health status among workers, even those who may have experienced drastic changes in their workplace and living environment after the Fukushima Daiichi Nuclear Power Plant accident. This study aimed to compare the workplace and living environment of workers in the evacuation area to the non-evacuation area, as well as the association between workplace communication and psychological distress.

Method
This cross-sectional questionnaire survey was conducted in two manufacturing companies in the evacuation area and a company in the non-evacuation area. Psychological distress was defined by a Kessler K6 distress scale score ≥5. Workplace communication was measured by the status of communication (“Do you feel that you can talk freely?”) and consultation (“Can you consult when having troubles?”) with superiors, managers and colleagues. Work burden, overtime, and irregular mealtimes as changes in the workplace and domestic life were determined. Differences in the workplace and living environment were compared using the chi-squared test, with the association between workplace communication and psychological distress analyzed by logistic regression.

Results
The proportion of workers with an increased work burden, overtime, and irregular meals was significantly higher among workers in the evacuation areas. There was also a significant association between low-psychological distress status and communication and consultation with superiors or managers, with no significant association with colleagues.

Conclusion
Only workplace communication with superiors or managers was associated with low-psychological distress, even after drastic changes in the workplace. Therefore, superiors or managers should initiate open communication and active consultation after a disaster.

ObjectiveAcute gout is among the most painful inflammatory arthritides and a frequent cause of emergency department (ED) visits. Prescription opioids are the leading contributor to the ongoing opioid epidemic; EDs are often the source of the index prescription. Our aim was to assess the burden of opioid use and factors associated with its use among gout patients discharged from the ED.MethodsIn the electronic health records system of Lifespan Healthcare System (currently contains 2.2 million records), adult gout patients discharged from the ED or hospital were identified using International Classification of Diseases, Ninth Revision or Tenth Revision diagnostic codes. The study period was March 2015 to September 2017, and only patients with a primary diagnosis of gout were included. If a patient was seen multiple times, only the first encounter was included. For these patients, we estimated the frequency, dose, and duration of opioids prescribed. Using multivariable logistic regression, we ascertained the factors associated with increased odds of opioid prescription at discharge among patients with acute gout.ResultsOf the 456 patients, 129 (28.3%) received opioids at discharge (~80% were new patients). The average dose of prescription was mean ± SD 37.9 ± 17.2 mg of morphine equivalent for a median duration of 8 days (interquartile range 5–14). We noted that patients with polyarticular gout attack and diabetes mellitus and those taking opioids prior to admission had higher odds of receiving opioids at discharge.ConclusionDespite the availability of effective treatments, opioids are commonly used for the management of acute gout. This study highlights an opportunity to curb the opioid epidemic among gout patients.
Living Materials Herald a New Era in Soft Robotics

Published: July 2019

AbstractLiving beings have an unsurpassed range of ways to manipulate objects and interact with them. They can make autonomous decisions and can heal themselves. So far, a conventional robot cannot mimic this complexity even remotely. Classical robots are often used to help with lifting and gripping and thus to alleviate the effects of menial tasks. Sensors can render robots responsive, and artificial intelligence aims at enabling autonomous responses. Inanimate soft robots are a step in this direction, but it will only be in combination with living systems that full complexity will be achievable. The field of biohybrid soft robotics provides entirely new concepts to address current challenges, for example the ability to self‐heal, enable a soft touch, or to show situational versatility. Therefore, “living materials” are at the heart of this review. Similarly to biological taxonomy, there is a recent effort for taxonomy of biohybrid soft robotics. Here, an expansion is proposed to take into account not only function and origin of biohybrid soft robotic components, but also the materials. This materials taxonomy key demonstrates visually that materials science will drive the development of the field of soft biohybrid robotics.

Published: July 2019

AbstractDespite the promise of ribonucleic acid interference therapeutics, the delivery of oligonucleotides selectively to diseased tissues in the body, and specifically to the cellular location in the tissues needed to provide optimal therapeutic outcome, remains a significant challenge. Here, key material properties and biological mechanisms for delivery of short interfering RNAs (siRNAs) to effectively silence target‐specific cells in vivo are identified. Using porous silicon nanoparticles as the siRNA host, tumor‐targeting peptides for selective tissue homing, and fusogenic lipid coatings to induce fusion with the plasma membrane, it is shown that the uptake mechanism can be engineered to be independent of common receptor‐mediated endocytosis pathways. Two examples of the potential broad clinical applicability of this concept in a mouse xenograft model of ovarian cancer peritoneal carcinomatosis are provided: silencing the Rev3l subunit of polymerase Pol ζ to impair DNA repair in combination with cisplatin; and reprogramming tumor‐associated macrophages into a proinflammatory state.

Published: July 2019

AbstractOrganic persistent room‐temperature phosphorescence (OPRTP) materials show great prospects in optoelectronic and biomedical applications, such as display, anti‐counterfeiting, sensing, and bioimaging. However, the reported OPRTP material systems are relatively rare, and it is a challenge to achieve the tunability of OPRTP. In this work, a series of polycyclic luminophores are developed based on an indole derivative (6,12‐diphenyl‐5,6,11,12‐tetrahydroindolo[3,2‐b] carbazole, Ben‐H) as the structural skeleton. These compounds unexpectedly exhibit dual OPRTP at 442 to 623 nm with lifetimes spanning from 2 to 759 ms. Experimental data and theoretical calculations suggest that CH⋅⋅⋅π interactions in the T‐shaped dimers facilitate the intermolecular charge transfer, resulting in OPRTP in the yellow spectral region, and the persistent blue emission results from the intramolecular charge transfer. This work contributes to better understand the key role of charge transfer in achieving OPRTP and broaden the scope of OPRTP materials.
Heterogeneous Gold(I)‐Catalyzed Oxidative Ring Expansion of 2‐Alkynyl‐1,2‐Dihydropyridines or ‐Quinolines Towards Functionalized Azepines or Benzazepines
Authors: Niu Bingbo , Nie Quan , Huang Bin , Cai Mingzhong 
Published: July 2019

AbstractA novel and efficient heterogeneous gold(I)‐catalyzed highly regio‐ and chemoselective oxidative ring expansion of 2‐alkynyl‐1,2‐dihydropyridines or ‐quinolines has been developed that proceeds smoothly through exclusive 1,2‐migration of a vinyl or phenyl group with pyridine N‐oxide as oxidant under mild conditions. The reaction provides a general and practical method for the synthesis of a wide variety of azepine derivatives with high atom‐economy, high to excellent yield, broad functional group tolerance, and recyclability of the gold(I) catalyst. The present method is an attractive alternative to construct functionalized azepines or benzazepines.magnified image

AbstractHigh‐transconductance stretchable transistors are important for conformable and sensitive sensors for wearables and soft robotics. Remarkably high transconductance, which enables large amplification of signals, has been achieved through the use of organic electrochemical transistors (OECTs). However, the stretchability of such systems has been tempered by the lack of stretchable conductors with high stability in electrolytes, high conductance at high strain (100%), and process compatibility with active layers. Highly stretchable and strain‐resistant Au conductors employed to fabricate intrinsically stretchable OECTs are demonstrated. Notably, the conductors exhibit a sheet resistance of 33.3 Ω Sq.−1 at 120% strain, the lowest reported value to date among stretchable Au thin film conductors. High‐performance stretchable Au is realized by suppressing strain‐induced microcrack propagation through control of the microcracks formed in deposited Au thin films. Then, the highly stretchable Au conductors are utilized to fabricate intrinsically stretchable OECTs with a high transconductance both at 0% strain (0.54 mS) and 140% strain (0.14 mS). Among previously reported systems, these OECTs show the highest transconductance at high strain (>50%). Finally, the high‐performance OECTs are utilized in stretchable synaptic transistors, which are critically important for the development of soft neuromorphic computing systems to provide artificial intelligence for future soft robotics.
Liberating and Empowering Effects of Critical Reflection on Collective Action in LGBT and Cisgender Heterosexual Individuals
Authors: Chan Randolph C. H. , Mak Winnie W. S. 
Published: July 2019

AbstractCritical consciousness represents the transformation from a passive target of oppression to an active actor with an increased capacity to analyze and negotiate conditions of oppression. It is considered as an antidote for oppression that can liberate people from oppressive ideologies and empower them to resist social injustice. Building on the theory of critical consciousness and the Social Identity Model of Collective Action, this paper examined the liberating and empowering effects of critical reflection on collective action for minority rights. Results of a cross‐sectional study in 1,050 LGBT individuals (Study 1) showed that critical reflection was associated with lower levels of internalized oppression and higher levels of collective efficacy, which in turn were associated with greater intentions to undertake collective action for LGBT rights. Findings from a prospective longitudinal study in 428 cisgender heterosexual individuals (Study 2) indicated that critical reflection was associated with lower levels of internalized domination and heightened levels of efficacious beliefs, which positively predicted actual participation in collective action at a subsequent wave. The findings supported the effects of critical reflection on collective action mobilization and offered leads for future research and praxis on how to orient different sectors of society to work toward social equity.
