Background

Shading includes low light intensity and varying quality. However, a low red/far-red (R/Fr) ratio of light is a signal that affects plant growth in intercropping and close- planting systems. Thus, the low R/Fr ratio uncoupling from shading conditions was assessed to identify the effect of light quality on photosynthesis and CO2 assimilation. Soybean plants were grown in a growth chamber with natural solar radiation under four treatments, that is, normal (N, sunlight), N + Fr, Low (L) + Fr, and L light.

Results

Low R/Fr ratio significantly increased the total biomass, leaf area, starch and sucrose contents, chlorophyll content, net photosynthetic rate, and quantum efficiency of the photosystem II compared with normal R/Fr ratio under the same light level (P < 0.05). Proteomic analysis of soybean leaves under different treatments was performed to quantify the changes in photosynthesis and CO2 assimilation in the chloroplast. Among the 7834 proteins quantified, 12 showed a > 1.3-fold change in abundance, of which 1 was related to porphyrin and chlorophyll metabolism, 2 were involved in photosystem I (PS I), 4 were associated with PS II, 3 proteins participated in photosynthetic electron transport, and 2 were involved in starch and sucrose metabolism. The dynamic change in these proteins indicates that photosynthesis and CO2 assimilation were maintained in the L treatment by up-regulating the component protein levels compared with those in N treatment. Although low R/Fr ratio increased the photosynthetic CO2 assimilation parameters, the differences in most protein expression levels in N + Fr and L + Fr treatments compared with those in N treatment were insignificant. Similar trends were found in gene expression through quantitative reverse transcription polymerase chain reaction excluding the gene expression of sucrose synthase possible because light environment is one of the factors affecting carbon assimilation.

Conclusions

Low R/Fr ratio (high Fr light) can increase the photosynthetic CO2 assimilation in the same light intensity by improving the photosynthetic efficiency of the photosystems.
Salicylic acid-primed defence response in octoploid strawberry ‘Benihoppe’ leaves induces resistance against Podosphaera aphanis through enhanced accumulation of proanthocyanidins and upregulation of pathogenesis-related genes
Authors: Feng Jun , Zhang Min , Yang Kang-Ning , Zheng Cai-Xia
Published: April 2020

Background

Podosphaera aphanis, a predominately biotrophic fungal pathogen, causes significant yield losses of strawberry. China is the largest strawberry producer in the world, and selecting for powdery mildew-resistant cultivars is desirable. However, the resistance mechanism against P. aphanis in the octoploid strawberry remains unclear.

Results

To understand possible mechanisms of disease resistance, we inoculated strawberry leaves with P. aphanis, and examined the expression profiles of candidate genes and the biochemical phenotypes in strawberry leaves of two groups. The unigenes obtained from ddH2O- and SA-pretreated leaves resulted in a total of 48,020 and 45,896 genes, respectively. KEGG enrichment showed that phenylpropanoid biosynthesis and plant hormone signal transduction pathways were enriched to a noticeable extent. DEG analysis showed that key TFs genes associated with the SA signaling pathway could play important role in the strawberry–P. aphanis interaction. In particular, FaWRKY70, FaJAZ1 and FaMYC2-like, involved in regulating the antagonistic effect of SA and JA signaling pathway, leading to increased expression of SA-responsive genes (in particular PR1, PR2, PR3, and PR5) compared to a decline in expression of JA-responsive genes (FaJAR1, FaAOS, and FaLOX2). Furthermore, SA pretreatment induced accumulation of PAs by activating the MBW complex and inhibit powdery mildew growth.

Conclusions

This study describes the role of the proanthocyanidins (PAs), pathogenesis-related (PR) genes, SA, and transcription factors in regulatory model against P. aphanis, which coincided with an early activation of defense, leading to the accumulation of PAs and the PR proteins.
New three-dimensional positioning algorithm through integrating TDOA and Newton’s method
Authors: Qu Junsuo , Shi Haonan , Qiao Ning , Wu Chen , Su Chang , Razi Abolfazl
Published: April 2020

Passive time difference location is an important method for passive location. There are fuzzy positioning, no solution, and low positioning accuracy with the spherical coordinate conversion method in the four-station TDOA positioning algorithm. Focusing on these problems, we proposed a combination of TDOA and iterative Newton’s method. The positioning method uses the result obtained by the four-station TDOA location algorithm as the initial value of the iterative Newton’s method and solves the problem of no solution and fuzzy positioning caused by the four-station TDOA location algorithm by using the spherical coordinates conversion method. By simulating the target at a height of 5 km and traveling at a constant speed for 40 km, the positioning accuracy of the root mean square error is less than 45 m, which can achieve the same positioning accuracy of TDOA based on the least square algorithm. As the baseline length increases, the positioning accuracy is better than the least square algorithm.

Numeric simulations are carried out to show the feasibility of the main results.
Bacterial cell division at a glance
Authors: Mahone Christopher R. , Goley Erin D.
Published: April 2020

Bacterial cell division is initiated by the midcell assembly of polymers of the tubulin-like GTPase FtsZ. The FtsZ ring (Z-ring) is a discontinuous structure made of dynamic patches of FtsZ that undergo treadmilling motion. Roughly a dozen additional essential proteins are recruited to the division site by the dynamic Z-ring scaffold and subsequently activate cell wall synthesis to drive cell envelope constriction during division. In this Cell Science at a Glance article and the accompanying poster, we summarize our understanding of the assembly and activation of the bacterial cell division machinery. We introduce polymerization properties of FtsZ and discuss our current knowledge of divisome assembly and activation. We further highlight the intimate relationship between the structure and dynamics of FtsZ and the movement and activity of cell wall synthases at the division site, before concluding with a perspective on the most important open questions on bacterial cell division.

Features of coincidence in fluctuations of various indicators are considered. The author draws conclusions about the coincidence in the dynamics of foreign direct investment, the dynamics of the dollar, the foreign trade balance of Russia and the turnover of organizations with foreign capital. The author points out that in the period between 2008 and 2014 there was a crisis period for companies with foreign capital from 2011 to 2012 due to the high amplitude of fluctuations in the us dollar on the Russian market.
Do Corporate Social Responsibility Engagements Lead to Real Environmental, Social, and Governance Impact?
Authors: Li Jun , Wu Di (Andrew)
Published: April 2020

We construct an event-based outcome measure of firm-level environmental, social, and governance (ESG) impact for public and private firms globally from 2007 to 2015 using data from RepRisk. Then we measure the societal impact of corporate social responsibility (CSR) engagements using participation in the United Nations Global Compact (UNGC) as a proxy. We demonstrate a robust and striking difference between public and private firms: whereas private firms significantly reduce their negative ESG incident levels after UNGC engagements, public firms fail to do so and are more likely to engage in decoupled CSR actions—actions with no subsequent real impact. We then conduct a series of in-depth analyses to examine possible economic mechanisms. Our results are most consistent with shareholder–stakeholder conflicts of interest being the main moderator of decoupling. The intensity of this conflict is further moderated by three factors: ownership type, proximity to final consumers on the value chain, and specific ESG incident types. Other possible mechanisms, such as selective entry into UNGC and heterogeneities in media exposure, country representation, and entry timing, do not survive our analysis. Our results suggest that existing CSR engagements and one-size-fits-all CSR policy mandates might not necessarily lead to better societal outcomes, and a multi-tiered policy targeting different ownership and industry types might be more efficient at maximizing ex post ESG benefits.

Empowering the woman: a comprehensive model of sexual anti-ageing
Authors: Sofra Xanya , Lampe Nuris
Published: April 2020

Female ageing is associated with sexual decline and well-documented symptoms of decreased metabolism, increased visceral fat deposits, decreased mobility, increased incidence of body aches and impaired self-confidence, which can lead to depression, marital dissatisfaction, conflicts or apathy. Sexual decline becomes more prominent with diabetic females suffering from neuropathy that is usually a challenge, since traditional methods usually offer temporary pain relief. Hormone replacement interventions treat only part of the systemic hormonal imbalance problem, ignoring the fact that disruption in the hormonal network signifies a disruption in the entire microcosmos of cellular communications leading to bio-disorganisation and health deterioration. New vaginal rejuvenation methods aspire to resolve a complex psychophysiological issue by merely improving vaginal laxity and dyspareunia, via invasive or minimally invasive methods that often reduce sexual sensation for women, while increasing male satisfaction during intercourse. Here, we offer a more comprehensive model of female sexuality, and discuss two new research studies performed entirely on female subjects. Both studies are discussed with respect to the multi-faced, psychophysiological, composite of female sexuality, which cannot show meaningful improvement without treating both its physiological and psychological components.
Understanding body image from a psychosocial stance: how this connects with patients requesting cosmetic procedures
Authors: Auer Deborah
Published: April 2020

There are many patients requesting cosmetic procedures who also struggle with mental health issues. These can include body dysmorphia, eating disorders, depression and anxiety. If aesthetic practitioners are able to recognise mental health, it will go some way to protect those for whom cosmetic procedures may not be the most appropriate course of treatment. This article will discuss the factors that contribute to the development of body image. The hope is that it will help practitioners question their own knowledge and understanding of mental health and how it can be connected with requests for cosmetic procedures. Practitioners may also identify areas where they need additional training and or understanding.
A comparison of handover communication in NHS and military emergency care
Authors: Slope Rowena , Pope Catherine , Crouch Robert , Bernthal Elizabeth MM
Published: April 2020

Background:

There is a gap in the literature comparing communication during handover between military and NHS emergency care settings.

Objectives:

This study aimed to explore differences in handover communication in the NHS and the military, and to understand how paramedics manage the transition between settings.

Design:

This was a qualitative study for which 13 paramedics were interviewed. It focused on handover communication in NHS emergency care settings and Camp Bastion Hospital, Afghanistan.

Methods:

Interviews were conducted with regular and reservist paramedics serving in the Royal Air Force who had undertaken a deployment with the Medical Emergency Response Team. Semi-structured interviews were recorded, transcribed, coded and subjected to a thematic analysis.

Results:

Three principal themes were identified: differences between handover communication; standardisation; and the challenge of transition.

Conclusion:

Participants were most concerned about standardisation. Transition theory and resilience may account for the difficulties encountered when transitioning between different care settings.
Propagation of positioning uncertainties in near-field goniophotometers using the Monte Carlo method
Authors: Pizág Bertalan , Vince Nagy Balázs
Published: April 2020

The method of near-field goniophotometry is used ever-increasingly to acquire detailed luminance information about various luminaires. It overcomes certain limitations of its predecessor, the widely used and thoroughly standardized far-field goniophotometry, and provides further opportunities to expand the scope of the measurement, but also introduces a new set of limiting factors. The aim of this paper is to examine the effect of positioning uncertainties on near-field goniophotometric measurements’ results. For this, a simplified ray tracing model is constructed computable in closed form as stacked matrix equations, in order to reduce the computation time as much as possible. The model is then fed to a simulated goniophotometric measurement, loaded with various uncertainties according to the Monte Carlo method. Finally, the resulting uncertainties are derived from statistical analysis of the output in both the near and far fields. Various metrics are tested as potential criteria for acceptance, including correlation and repeated measures ANOVA tests, both faring well until the angle of incidence of the rays is below 55°, the ANOVA test being more sensitive to sampling and rejecting systems with 0.1° angular error and above, while the same results still pass the correlation test until 0.5°. Converted far-field results are compared to the standardized requirements, indicating the necessity of similar mechanical precision.
Fundamental ray aberration analysis: extension of ray matrix analysis to the third-order region using a four-element fundamental ray vector
Authors: Mori Kentaro , Hayasaki Yoshio , Araki Keisuke
Published: April 2020

We have developed a new fundamental ray aberration analysis that
extends conventional ray matrix analysis to the third-order region
using a four-element fundamental ray vector. This analysis method can
analyze the factors in the generation of the Seidel aberration
coefficients by separating them into the transform characteristics of
rays unique to the optical system and paraxial trace values
representing the conjugate relationship. In establishing this
analysis, we first introduce the fundamental ray aberration, and we
present calculation formulae for the fundamental ray aberration
coefficients of a co-axial rotationally symmetric optical system.
Numerical examples employing these analysis results are shown, and it
is confirmed that the causes of the Seidel aberration coefficients can
be analyzed.

Aberration-free 3D imaging via DMD-based two-photon microscopy and sensorless adaptive optics
Authors: Ren Mindan , Chen Jialong , Chen Dihan , Chen Shih-Chi
Published: April 2020

In this Letter, we present a new, to our knowledge, aberration-free 3D imaging technique based on digital micromirror device (DMD)-based two-photon microscopy and sensorless adaptive optics (AO), where 3D random-access scanning and modal wavefront correction are realized using a single DMD chip at 22.7 kHz. Specifically, the DMD is simultaneously used as a deformable mirror to modulate a distorted wavefront and a fast scanner to maneuver the laser focus in a 3D space by designed binary holograms. As such, aberration-free 3D imaging is realized by superposing the wavefront correction and 3D scanning holograms. Compared with conventional AO devices and methods, the DMD system can apply optimal wavefront correction information to different imaging regions or even individual pixels without compromising the scanning speed and device resolution. In the experiments, we first focus the laser through a diffuser and apply sensorless AO to retrieve a corrected focus. After that, the DMD performs 3D scanning on a Drosophila brain labeled with green fluorescent protein. The two-photon imaging results, where optimal wavefront correction information is applied to

separate regions, demonstrate significantly improved resolution and image quality. The new DMD-based imaging solution presents a compact, low-cost, and effective solution for aberration-free two-photon deep tissue imaging, which may find important applications in the field of biophotonics.

A Mouse Model for Studying Stem Cell Effects on Regeneration of Hair Follicle Outer Root Sheaths
Authors: Guo Jingxu , Li Shuwei , Wang Hongyang , Wu Tinghui , Wu Zhenhui , Yu Lufei , Liang Meiyan
Published: April 2020

Objective

Stem cells hold promise for treating hair loss. Here an in vitro mouse model was developed using outer root sheaths (ORSs) isolated from hair follicles for studying stem cell-mediated dermal papillary regeneration.

Methods

Under sterile conditions, structurally intact ORSs were isolated from hair follicles of 3-day-old Kunming mice and incubated in growth medium. Samples were collected daily for 5 days. Stem cell distribution, proliferation, differentiation, and migration were monitored during regeneration.

Results

Cell proliferation began at the glass membrane periphery then spread gradually toward the membrane center, with the presence of CD34 and CD200 positive stem cells involved in repair initiation. Next, CD34 positive stem cells migrated down the glass membrane, where some participated in ORS formation, while other CD34 cells and CD200 positive cells migrated to hair follicle centers. Within the hair follicle matrix, stem cells divided, grew, differentiated and caused outward expansion of the glass membrane to form a dermal papillary structure containing alpha-smooth muscle actin. Neutrophils attracted to the wound site phagocytosed bacterial and cell debris to protect regenerating tissue from infection.

Conclusion

Isolated hair follicle ORSs can regenerate new dermal papillary structuresin vitro. Stem cells and neutrophils play important roles in the regeneration process.

Published: April 2020

Feedback design is an important aspect in person-following robots for older adults. This paper presents a user-centered design approach to ensure the design is focused on users’ needs and preferences. A sequence of user studies with a total of 35 older adults (aged 62 years and older) was conducted to explore their preferences regarding feedback parameters for a socially assistive person-following robot. The preferred level of robot transparency and the desired content for the feedback was first explored. This was followed by an assessment of the preferred mode and timing of feedback. The chosen feedback parameters were then implemented and evaluated in a final experiment to evaluate the effectiveness of the design. Results revealed that older adults preferred to receive only basic status information. They preferred voice feedback over tone, and at a continuous rate to keep them constantly aware of the state and actions of the robot. The outcome of the study is a further step towards feedback design guidelines that could improve interaction quality in person-following robots for older adults.

Biblijny motyw bramy. Jezus jako brama w J 10, 7.
Authors: Walczak Małgorzata
Published: April 2020

Jednym z samookreśleń Jezusa, występującym w Ewangelii jest θύρα (J 10, 7.9), które oznacza m.in. bramę. Pierwsza część artykułu prezentuje biblijną terminologię używaną do jej opisu (שַׁעַר, פֶּתַח, דֶּלֶת, πύλη, θύρα, εἴσοδος, πυλών), aby następnie przejść do analizy funkcji z nią związanych. Liczne bowiem funkcje bramy i jej kulturowe znaczenie pomagają w interpretacji tych słów Jezusa. Jezus określa siebie jako bramę, ponieważ daje bezpieczeństwo swoim owcom możliwość przejścia w bezpieczną sferę. W Nim dokonują się prawdziwe sądy oraz liturgia. Chrystus jawi się również jako Ten, który jest zabezpieczeniem potrzeb tych, którzy za Nim idą, a także reprezentuje ich, jako głowa stada.
Miłosierdzie w homiliach św. Jana Chryzostoma na Ewangelię według św. Mateusza
Authors: Baron Arkadiusz
Published: April 2020

Artykuł podejmuje problem Bożego miłosierdzia w ujęciu homilii św. Jana Chryzostoma na Ewangelię według św. Mateusza i św. Jana Chryzostoma na Ewangelię według św. Mateusza oraz jego rolę w życiu chrześcijańskim. Miłosierdzie jest imieniem Boga. Chryzostom uważa, że Boże miłosierdzie jest jedyną racją Wcielenia Syna Bożego, ponieważ przyjął On ludzkie życie, aby wybawić ludzi od wszelkich chorób i zła. Dlatego miłosierdzie stanowi istotę chrześcijańskiego życia. Chryzostom podkreśla, że nagród za miłosierdzie okazane ludziom w ciągu życia doczesnego nie można porównywać z Bożym miłosierdziem, ponieważ ludzkie miłosierdzie dokonuje się w sprawach doczesnych, a Boże miłosierdzie oferuje wieczne zbawienie. Boże miłosierdzie zawsze jest powiązane ze zbawieniem, które ludzie mogą otrzymać bez udziału człowieka i bez żadnych warunków; potrzebne jest natomiast tylko nawrócenie i przebaczenie.Miłosierdzie jest tak ważne dla autentycznego życia chrześcijańskiego, że chrześcijanie powinni uczyć się go udzielać przez całe życie. Bóg Ojciec i Jezus Chrystus są jego najlepszymi nauczycielami. Miłosierdzie jest miarą człowieczeństwa. Człowiek niemiłosierny jest duchowo martwy nawet jeśli jeszcze żyje życiem doczesnym. Kara za brak miłosierdzia jest wieczna. Nie jest autentycznym miłosierdziem obdarzanie innych nie swoimi lub nieuczciwie zdobytymi dobrami.

Większość zamienników umożliwia zmianę długiej i uciążliwej pokuty postu o chlebie i wodzie na krótszą i mniej uciążliwą, a nawet na zmianę formy pokuty postnej na odmówienie modlitw (np. psalmów, Ojcze nasz itp.), klękanie, a w przypadku ludzi zamożnych na przekazanie odpowiedniej sumy pieniędzy na jałmużnę dla biednych, dla mnichów lub na potrzeby kościoła. Problemem teologicznym związanym z zamiennikami pokuty jest łatwa formalizacja i minimalizacja otrzymanej pokuty, czyli praktykowanie rytów chrześcijańskich bez autentycznego nawrócenia, do którego wzywał Jezus.
Analysis of multiphase flow characteristics in a deepwater riser
Authors: Liang Weixing , Lou Min
Published: April 2020

Oil and gas mixed transportation is an important technology in oil and gas production. Multiphase fluid is transported from the wellhead to the floating platform through a riser system. Based on computational fluid dynamics, a numerical model of multiphase flow in a deepwater riser by considering hydrate phase transformation and sand production was established, which was then solved by the finite-difference method. The results show that under constant inlet pressure, the pressure drop decreases with increasing gas–liquid two-phase flow rate, and increases with increasing sand production rate. Furthermore, the hydrate phase transition decreases the pressure. The effect of liquid on the temperature in the riser is apparent: the heat transfer between the fluid and seawater is mitigated by the insulation layer, thus raising the critical point of the hydrate phase transition. Finally, the velocity and volume fraction of the gas phase increase from the inlet to the outlet of the riser. At the same time, the velocity of the liquid–solid phase increases, whereas the volume fraction decreases.

Authors: St-Jean Sabine , Laliberté Etienne
Published: April 2020

Here we describe the standardised protocol used by the Canadian Airborne Biodiversity Observatory (CABO) to take small drone pictures of the plots and subplots in open vegetation surveys. In 2019, such pictures were taken at the Mer Bleue Bog (Ontario) and Parc national des Îles-de-Boucherville (Québec) sites. These pictures are to be classified later (see the Post Processing protocol) to obtain the abundance and distribution of plant species through every subplot.

Published: April 2020

Background and Objectives: Excess use of pesticides in agricultural field not only compromised soil fertility but also posed serious threat to water bodies and life in the surrounding environment. The leftover pesticide residue needs to be remediated effectively. Compared to physical, chemical and enzymatic remediation options the microbial remediation is more practical and sustainable.
Materials and Methods: The Pseudomonas stutzeri smk strain was found to use dichlorvos as the solitary carbon source. Minimal medium supplemented with dichlorvos was used to test ability of bacterium to degrade pesticide aerobically. The metabolites produced by the bacterium were studied with UV-Vis spectrophotometry, HPLC, FTIR and GC-MS techniques. The toxicity studies of neat dichlorvos and P. stutzeri smk degraded metabolites were studied by subcutaneous injection in Mus musculus.
Results: The P. stutzeri smk strain was found to degrade as high as 80% of dichlorvos on 7th day of incubation, at 30 °C tem- perature and at pH 7. In five steps complete aerobic degradation of 2,2dicholorvinyl dimethyl phosphate (dichlorvos) resulted in production of free methyl and phosphate. The degradation intermediates produced are 2-Chlorovinyl dimethyl phosphate, vinyl dimethyl phosphate, dimethyl phosphate, methylphosphate and finally free phosphate. The histopathological analysis of liver, spleen and thymus of M. musculus were performed to study toxicity of dichlorvos and degraded metabolites. Conclusion: P. stutzeri smk could result highest aerobic degradation of dichlorvos to produce free methyl and phosphate. Degradation metabolites could reverse largely toxic effects of dichlorvos when studied in M. musculus.

Objective: The practice of breastfeeding is considered a blessing since its effects on health are well recognized and applies to both mothers and infants. The objective of this study was to evaluate the effectiveness of peer support and training on breastfeeding initiation, duration and exclusivity.
Materials and methods: This community-based clinical trial, (IRCT No: 201504049568N12), was conducted during 2015 in the Municipality of Tehran 19 District. First, a total of 150 mothers with their infants from 4 to 20 months of age were asked to complete a questionnaire, which included the demographic characteristics, educational level, and the type of lactation, the initial age of infant for breastfeeding, and the duration of exclusive breastfeeding. Afterwards, 25 volunteer women were selected for lactation counseling. After 6 months, another sample of 116 nursing mothers in the region who had received peer counseling was selected and questioned through the previously mentioned questionnaire. Finally, the results, which were collected from the behavior of the target population before and after the intervention, were compared.
Results: The results of the present study indicated that the nursing mothers who received peer counseling proved to have longer durations of breastfeeding (P-value = 0.039), and higher frequency of first hour initiation of breastfeeding (P-value = 0.003) however, the volunteer counselors were mainly housewives who had lower levels of education (P-value = 0.009) and were younger (P-value = 0.009) than those of untrained control group.
Conclusion: The study demonstrated the significant effect of peer counseling on breastfeeding initiation and continuation. It is suggested that lactation training could be initiated during the prenatal period along with the conventional methods of training.

Inventory Accounting System Using System Engineering Methods
Authors: . O.Yashina
Published: April 2020

The article presents models of inventory accounting led by a project manager and system engineer. The project “Inventory accounting system using system engineering methods” is aimed at the formation of a separate inventory accounting system in   the development, manufacture and production of products. In the framework of Ural Diesel Engine Plant LLC, such records are kept only for expensive components that are delivered with military acceptance in the context of each contract for each state contract. Even with such accounting at the enterprise, there is a problem of making small profits or lack of profit from the manufacture of military diesel generators. In developing my project, I would like to improve the system of accounting and writing off inventory items supplied with military acceptance, and later using this system for the entire list of components that make up the product.
