Authors: Destéfano Suzete Aparecida Lanza , Vitor Lucas , Corrêa Daniele Bussioli Alves , Tomaseto Alex Augusto , Monteiro Regiane Pinheiro dos Santos
Published: October 2021

A sarna da batata, de ocorrência generalizada nas principais regiões produtoras do Brasil e do mundo, é considerada como uma das doenças bacterianas mais importantes que afetam a cultura. Sua incidência vem aumentando, tornando-se um fator limitante na produção da batata no Brasil. A sarna é causada por diferentes espécies do gênero Streptomyces, sendo S. scabiei a espécie mais amplamente distribuída. Os sintomas se caracterizam por lesões superficiais ou profundas que podem afetar toda a superfície do tubérculo, acarretando diminuição do seu valor comercial e até mesmo impedindo a sua comercialização. Os mecanismos de patogenicidade de Streptomyces são considerados altamente evoluídos, e diferentes fatores de patogenicidade estão envolvidos nos processos de penetração, colonização e evasão do sistema de defesa da planta, como a fitotoxina taxtomina A, a proteína necrogênica Nec1 e a enzima tomatinase. Entretanto, algumas espécies fitopatogênicas causadoras da sarna não produzem taxtomina, nem a proteína Nec1, indicando que outras vias metabólicas estão envolvidas na patogenicidade dessas espécies. Considerando os fatores favoráveis ao desenvolvimento da doença, diferentes estratégias de controle podem ser adotadas, a fim de se reduzir a incidência e severidade da sarna. Medidas de controle como plantio de cultivares resistentes, certificação de batata-semente, tratamento dos tubérculos antes do plantio e controle químico ou biológico têm sido empregadas. Entretanto, ainda não há um método com total eficácia. Nesta revisão, serão apresentados e discutidos aspectos relevantes sobre o histórico da sarna da batata, etiologia, ciclo de vida do patógeno, distribuição mundial, determinantes de patogenicidade, medidas de manejo e técnicas de identificação do agente causal.
The effect of high-penetrating emission on the growth, superoxide accumulation and ATP/ADP ratio in Saccharomyces cerevisiae
Authors: Qing Li , Miao Tian , Peng Gao , Jie Teng , Bing Wang , Qing Tang Bruce , Hong Wu
Published: October 2021

Many kinds of physical fields are able to affect biological activity, such as electromagnetic field, magnetic field, scalar wave, magnetic vector potential and so on. Some works investigated a high-penetrating emission (HPE) generated by a LED generator that can affect the conductivity of water and the growth of dry yeast. In this research, the biological effect of the HPE of LED generator on S. cerevisiae was studied. The results showed that this kind of HPE could promote the growth of S. cerevisiae. With the decrease of initial concentration and the extension of exposure time, the growth promoting effect of HPE increased significantly. When the initial cell concentration was 2 × 102 cell/ml and exposed for 24 h, the number of yeast cells increased by 19.5% compared with the control group. Further studies showed that adenosine triphosphate (ATP) content and the ratio of ATP and adenosine diphosphate (ADP, ATP/ADP ratio) of exposed cells were higher than those of unexposed cells, indicating that exposed cells had higher cell viability and energy status. In addition, the intracellular superoxide (O2 −) content decreased significantly after the HPE exposed. In this study, the stainless steel box acts as a Faraday cage to shield the electromagnetic field, so the biological effect of the HPE is not produced by the electromagnetic field. Nevertheless, the mechanism of the HPE is still unknown and needs further research. This is the first report on the effect of HPE on mitochondrial parameters, contributing to further study on HPE and revealing potential for future medical applications.
Integrating AI Microservices into Hard-Real-Time SoS to Ensure Trustworthiness of Digital Enterprise Using Mission Engineering
Authors: Murphy Alvin C. , Moreland James D.
Published: October 2021

Due to the increased complexities and operating speeds of today’s and tomorrow’s system-of-systems (SoS) architectural configurations for digital enterprises, the design of new domain architecture management systems is required. A key element of these new designs will be the incorporation of Artificial Intelligence (AI) microservices to provide dynamically containerized and orchestrated service capabilities within a lightweight interoperability fabric with the ability to operate in hard-real-time environments. Each containerized AI microservice exposes an independent, programmable function, which enables it to be easily reused, evolved, or replaced without compromising interoperability across critical mission essential functions to execute mission threads. In addition, embedded in this design needs to be a trust management layer to enforce reliable messaging and trust amongst the actors. This paper provides a framework for planned research and demonstrates the feasibility of microservices using a representative simple problem to demonstrate the application of the framework. Early positive analysis results using AI microservices within an SoS environment shows that the 500 milli-second (ms) threshold for latency can be met.

Authors: Hajaghazadeh Mohammad , Taghizadeh Mohsen , Khalkhali Hamidreza , Mohebbi Iraj
Published: October 2021

BACKGROUND: Hand anthropometry is useful for designing manual systems such as hand tools, controls, and gloves. There are limited published data on the hand dimensions of Iranian male and female adults. OBJECTIVE: This study was undertaken to measure the hand anthropometric dimensions in Iranian adults to compare data between two genders and also with the corresponding data from other nationalities. METHODS: A total of 34 dimensions of the right hand were measured in 217 male and 128 female adults using a digital caliper and tape. The mean, standard deviation, and the main percentiles are summarized in a table and the mean of each dimension is compared by independent t-tests between genders. Hand dimensions are compared between Iranian and other nationalities such as North Colombian, Korean, Turkish, Nigerian, Bangladeshi, Jordanian, and Vietnamese using the published data. RESULTS: Females had significantly smaller hand dimensions than males in all dimensions ranged from 4.21%to 18.16%, with the largest differences in hand breadths. Compared with other nationalities, the Iranian male and female adults had wider (greater breadth and circumferences) hands with shorter fingers. CONCLUSIONS: The results showed significant differences of hand anthropometry between Iranian and other nationalities which should be included in the design and selection of hand tools for Iranian population.

Authors: Hoque Mojahidul , Halder Pobitra , Rahman Sumon , Ahmed Tazim , Szecsi Tamas
Published: October 2021

BACKGROUND: In Bangladesh, workers typically spend at least eight hours a day at garment factories in sitting and/or standing position. Prolonged sitting on ergonomically unfit furniture causes back, neck, and shoulder pain, which reduces the working efficiency and leading to low productivity. OBJECTIVE: The aim of this study is to design ergonomically correct furniture for Bangladeshi garment workers considering multivariate analysis on the anthropometric data. METHODS: Twelve anthropometric measures and five furniture dimensions were measured. The sample comprised of 600 volunteer workers from different garment industry. The furniture dimensions were compared with the relevant anthropometric characteristics and found a high level of mismatch (e.g. seat height (male 18%, female 94.25%), seat depth (male 96%, female 63.50%), seat width (male 9.50%, female 36.25%), sewing table height (male 56.50%, female 50%), and desk height for inspection, cutting and ironing table (male 100%, female 100%). RESULTS: New design specifications were proposed of the worker which improved the match percentage. The multivariate anthropometric analysis generated 8 cases and for each case the ranges of anthropometric measurements have been identified. CONCLUSION: The results will help to design robust ergonomic garments furniture.

Authors: Hsia Michelle
Published: October 2021

The objective of this study was to analyze, among a nationally representative sample of college students in the U.S., gender differences in the lifetime, past 12-months, and past 30-day prevalence of e-nicotine products (ENPs) use, reasons for use, and susceptibility to ENP use among never users. We analyzed data from the Population Assessment of Tobacco and Health (PATH) Study. The study population included college-aged individuals (18-24 years old) enrolled in a degree program. The results of the study revealed that males were more likely to use ENPs than females. Both males and females reported a high proportion of misconception about ENPs, particularly with regards to ENPs being less harmful to the user than cigarettes. It also indicated that 36% of male and 32% of female college students were susceptible to start using ENPs. Our results highlight the need to provide comprehensive, tobacco-prevention education among U.S. youth.
A Newfound Empathy
Authors: Chamberlain Shannon Rose
Published: October 2021

The Boston Massacre occurred on March 5, 1770. Following the death of five Bostonians, both the American colonists and the royal officials in Boston took testimonies and sent them to London. Elected colonial agents issued motions to open debate on Parliament’s accountability in creating an imbalanced relationship between the military and civil authorities in the colonies. Unfortunately, the motions from these colonial agents were voted in the negative, leading to disappointment on both sides of the Atlantic. Two years prior, a similar tragedy happened in England: The Massacre of St. George’s Fields. Scottish soldiers accosted a British mob that had gathered to protest the arrest of MP John Wilkes. From 1768 to 1771, Parliament rejected motions that sought to reconcile the grievances that led to the Massacre of St. George’s Fields. After years of Parliament silencing colonial agents and liberal politicians, the British public began to express a stronger sense of understanding and empathy towards the American colonists, as evident by the outpouring of public support in the months following the Boston Massacre.

Objective: To identify the morphometric and biochemical variation in mango fruits var. Ataulfo (Mangifera indica L.) in two contrasting environments with and without conventional management.
Design/methodology/approximation: Morphological and biochemical variables were studied in mango fruits var. Ataulfo in two environments, one of them (La Norteña) with Leptosol soil and Aw climate with conventional agrochemical-based management and the other (Santa Cecilia) on Acrisol soil and Am climate with agroecological management. There were 30 fruits used, all from five trees (n=150) per study garden in a state of commercial maturity. Each fruit was considered as an experimental unit, and morphological and biochemical variables were evaluated for each fruit.
Results: Increase in fruit weight, higher pH and increase in total soluble solids, but decrease in pulp weight on site with conventional handling. Increase in pulp content and firmness in fruits from the site without handling.
Study Limitations/implications: Changes in the amount and distribution of rainfall in both environments each year.
Findings / conclusions: Morphological and biochemical modifications are presented. Greater size and weight, pH and TSS content in the conventional production system, but increased pulp and greater firmness, as well as higher citric acid content in the agroecological system. The results suggest differential effects in mango fruits according to the management and environment where they develop.

Objective: Evaluate the physical-chemical properties and characterize the microstructure of four varieties of traditional Mexican chili (Capsicum annuum L.) powders: “Arbol”, “Guajillo”, “Piquin” and “Mole ranchero” (Ancho chili).

Design/methodology/approach: Physical-chemical properties of chili powders were evaluated by means of moisture content, particle size, aerated and tapped bulk density, Carr index, Hausner ratio, angle of repose (flow properties), capsaicin, and carotenoids content. Microstructure of samples was characterized by Confocal Laser Scanning Microscopy and Scanning Electron Microscopy. ANOVA analysis and Tukey test were performed to evaluate the significant statistical difference between samples at 95% of confidence level.

Results: “Arbol”, “Guajillo”, “Piquin” and “Mole Ranchero” chili powders presented a cohesive behavior respect to its flow properties related to aerated and tapped bulk density, angle of repose, Carr Index, and Hausner ratio values under moisture content between 6.59-14.48 gH2O/100g d.s. “Arbol” and “Piquin” chili powders presented the higher capsaicin content, while “Guajillo” and “Mole ranchero” showed the higher carotenoids content. FTIR spectra confirmed the presence of secondary amide, phenolic groups, alkanes, and aliphatic chains that belong to capsaicin structure at specific absorption bands. Microstructure of chili powders presented particles with surface imperfections as cracks and dents, and smooth surface that influence physical-chemical and flowability properties.

Limitations on study/implications: Hight moisture content affect the physical-chemical properties, flowability and microstructure of traditional Mexican chili powders.

Findings/conclusions: Moisture content between 6.59 and 14.48 gH2O/100g d.s. influences the physical-chemical properties, flowability and microstructure of traditional Mexican chili powders. To improve physical-chemical properties and flowability behavior of chili powders is required that moisture content be lower than 6.59 H2O/100g d.s.

SOUTH UKRAINIAN REGION: FRENCH COMPONENT AT THE END OF XVIIІ – XIX CENTURY
Authors: H. Batenko
Published: October 2021

The purpose of the work.The south of modern Ukraine has always been geographically and historically particularly interesting for researchers. Its geographical indicators make it possible to analyze theories of the origin of man, development, formation of human society under the influence of climatic conditions to its highest degree - its own independent state. The Soviet state’s rather popular concepts, designed to artificially unite and forcibly bring peoples together in tsarist Russia, have not withstood the test of time and history. The use of the concept of the South Ukrainian region requires a definition: we move freely through the territory of modern Kherson, Odessa, Mykolaiv, Zaporizhia regions and the Autonomous Republic of Crimea.Results and scientific novelty of the studyAccording to the chronology, scientists use the names Little Russia, New Russia, contained in primary sources, archival documents, memoirs, correspondence. The presence of the French component in the culture, history, mentality of the population of the region give grounds for reflections on demographic data. A relatively small number of representatives of France have influenced the culture, economy, domestic policy, self-identification of the inhabitants of our region. Accordingly, the German colony, the Swedish village, the Bulgarian, Greek settlements in the history of the region are present and studied, as for the French - there are no such clear characteristics.Key words:regional history, demographic research, South of Ukraine, French culture, education, religious factor. Мета роботи. Південь сучасної України географічно та історично завжди був особливо цікавим для дослідників. Його географічні показники дають можливість проаналізувати теорії виникнення людини, розвитку, формування людського суспільства під впливом кліматичних умов до його найвищої ступеня – власної незалежної держави. Достатньо популярні концепції, розраховані на штучне об’єднання та насильницьке зближення народів на території царської Росії, радянської держави не витримали випробування часом та історією. Використання поняття Південноукраїнський регіон вимагає визначення: ми вільно переміщуємося територією сучасних Херсонської, Одеської, Миколаївської, Запорізької областей та Автономною республікою Крим. Результати та наукова новизна дослідження. Присутність французької компоненти в культурі, історії, ментальності населення краю дають підстави для рефлексій, щодо демографічних даних. Відносно невелика кількість представників Франції справила вплив на культуру, економіку, внутрішню політику, самоідентифікацію мешканців нашого краю. Відповідно, німецька колонія, шведське село, болгарські, грецькі поселення в історії краю присутні і досліджуються, щодо французів – таких чітких характеристик немає.

This study was conducted to determine the suitability of water quality for fisheries management in Kaptai Lake from February 2019 to January 2020. Results showed that the temperature, transparency, TDS, pH, DO, EC, alkalinity and hardness were 20.9 to 31.8°C, 17 to 303 cm, 40 to 105 mg/L, 6.82 to 7.96, 6.1 to 7.65 mg/L, 75.33 to 172.33 µS/cm, 37 to 83 mg/L and 35 to 190 mg/L, respectively. However, nutrients as NH3, NO3-, NO2-, PO43- and SO42- were 0.01 to 0.05, 0.03 to 2.21, 36 to 96, 0.01 to 0.04 and 0.3 to 1.9 mg/L, respectively. Chlorophyll a and trophic state index (TSI) were 0.70 to 2.12 µg/L and 27.43 to 37.79, respectively. Study revealed that SO42-, DO and TDS were higher than the standard of ECR. On the other hand, NH3, NO3-, NO2-, PO43-, temperature, transparency, pH, EC, total hardness, total alkalinity, Chlorophyll a and TSI were within the standard levels. Concentrations of NO3-, NO2-, PO43-, Chlorophyll a and TSI (CHL) showed no significant variation with seasons. Conversely, TDS, transparency, EC, alkalinity, hardness, and SO42- were lower in monsoon compared to pre-monsoon and post-monsoon seasons. Besides, temperature, NH3, DO and TSI (SD) were higher in monsoon season. Results concluded that the Kaptai Lake is in mesotrophic condition with TSI (CHL) less than 40, and prominently there was a positive relationship between Chlorophyll a and Trophic State Index (TSI). In this regard, major nutrients and Chlorophyll a concentration in the Kaptai Lake may have an impact on the aquatic environment.

Галузева належність корпоративних відносин і проблеми їх законодавчого регулювання
Authors: ЩЕРБИНА ВАЛЕНТИН
Published: October 2021

У статті проаналізовано визначення понять “корпоративні права” та “корпоративні відносини”. Звертається увага на недоліки існуючих законодавчих визначень цих понять і вносяться пропозиції щодо їх зміни.
Зазначено, що законодавче визначення поняття корпоративних прав є надто широким, оскільки воно може стосуватися будь-якої господарської організації, включаючи унітарне підприємство (державне, комунальне чи приватне). Тому автор вважає, що корпоративні права можуть належати лише учаснику (засновнику, акціонеру) корпоративного підприємства (крім повних і командитних товариств) та кооперативу. Наводяться аргументи щодо невиправданого віднесення Цивільним кодексом України кооперативів до господарських товариств.
Зроблено висновок, що корпоративні відносини за своєю юридичною природою є господарськими (із майново-господарськими й організаційно-господарськими елементами), а не цивільно-правовими відносинами. На підтвердження цього наводяться такі аргументи: конкретний суб’єктний склад корпоративних відносин (наявність серед суб’єктів корпоративних відносин органів господарської організації корпоративного типу); відсутність юридичної рівності суб’єктів корпоративних відносин; головним чином, організаційний характер відносин корпоративного управління; відносний характер майнової незалежності суб’єктів корпоративних відносин.
Таким чином, корпоративні відносини можна кваліфікувати як внутрішньогосподарські відносини, правове регулювання яких повинно здійснюватися нормами господарського (економічного) законодавства (насамперед Економічного кодексу України та законами про певні види товариств і кооперативів), підгалуззю якого є корпоративне законодавство, а також локальними нормативними актами.
Однак не виключено, що з часом корпоративне законодавство може бути кодифіковане в Корпоративному кодексі України. Така кодифікація дасть змогу уникнути невиправданого дублювання норм для певних видів товариств, призведе до значного зменшення кількості правил щодо них та їх уніфікації, а також посилить принципи корпоративного управління (не лише для акціонерних, а й для інших видів товариств і кооперативів) на рівні закону.
Стверджується, що визнання корпоративних відносин категорією цивільного права може призвести до того, що справи у спорах, що виникають із корпоративних відносин, і охоплюються поняттям “справи у спорах, що виникають у зв’язку зі здійсненням господарської діяльності”, які нині розглядаються господарськими судами України (п. 3 ч. 1 ст. 20 Господарського процесуального кодексу України), будуть визнані цивільними справами, а отже, передані до цивільної юрисдикції загальних судів.

INTRODUCTION: Research has highlighted the significant impact that jet lag can have upon performance, health, and safety. International business travelers have an important role in economic growth; however, there is a lack of research investigating jet lag and jet-lag management
in international business travelers. This study aimed to investigate international business travelers use of jet-lag countermeasures. METHODS: International business travelers from Australia (N = 107) participated in a survey examining use of jet-lag countermeasures (pharmacological
and nonpharmacological). Chi-squared tests were conducted examining the association between duration of stay and traveling experience on jet-lag countermeasure use. RESULTS: Most subjects had traveled for business for less than 15 yr and 57% reported taking between 14 trips annually.
Durations of stay averaged 10 d (SD 13 d). Nonpharmacological countermeasure use was high. Pharmacological countermeasure use was less common. There were no significant associations between duration of stay and countermeasure implementation. Travel experience was only associated with nonpharmacological
countermeasures after arrival home. CONCLUSION: Education programs delivered through businesses would be beneficial for providing information on jet lag, its implications, and recommended countermeasures to travelers. Rigney G, Walters A, Bin YS, Crome E, Vincent GE. Jet-lag

This study explores vocational judgement, which is discernible in the assessment actions of a supervising childminder directed towards upper secondary school students – while interacting with the children – during work-based learning in Sweden. The research aims to identify the characteristics of vocational knowing in terms of judgement, as exhibited in everyday interactions with children, by applying multimodal interaction ana-lysis to two video sequences from different Swedish preschools. The study findings show how vocational judgement – in the form of embodied discernment – is a central aspect of a childminder’s vocational knowing. Vocational judgement becomes discernible, for instance, in how supervising childminders are consistently one or several steps ahead of both children and upper secondary school students
Longitudinal Modulation of Marangoni Wave Patterns in Thin Film Heated From Below: Instabilities and Control
Authors: Samoilova Anna , Nepomnyashchy Alexander
Published: October 2021

Non-linear Marangoni waves, which are generated by the long-wave oscillatory instability of the conductive state in a thin liquid film heated from below in the case of a deformable free surface and a substrate of very low conductivity, are considered. Previously, the investigation of traveling Marangoni waves was restricted to the analysis of the bifurcation and stability with respect to disturbances with strongly different wave vectors. In the present article, for the first time, the modulational instability of traveling waves is investigated. We derive the amplitude equation for the modulated traveling wave, which describes non-linear interaction of the main convective pattern with the perturbations with slightly different wavenumbers. The amplitude equation differs from the conventional complex Ginzburg–Landau equation as it contains an additional term of the local liquid level rise. Linear stability analysis reveals two modulational instability modes: the amplitude modulational and the phase modulational (Benjamin–Feir) ones. It is shown that traveling rolls are stable against the longitudinal modulation for the uncontrolled convection. We also investigate the influence of the non-linear feedback control, which was applied previously to eliminate subcritical excitation of traveling rolls. Computations reveal both the modulational modes under the non-linear feedback control. The obtained results show that the modulational instabilities significantly influence the region of parameters where the non-linear feedback control is efficient for stabilization of waves.

The significance of biomaterials is well appreciated in nanotechnology, and its use has resulted in major advances in biomedical sciences. Although, currently, very little data is available on the clinical trial studies for treatment of neurological conditions, numerous promising advancements have been reported in drug delivery and regenerative therapies which can be applied in clinical practice. Among the commonly reported biomaterials in literature, the self-assembling peptides and hydrogels have been recognized as the most potential candidate for treatment of common neurological conditions such as Alzheimer’s, Parkinson’s, spinal cord injury, stroke and tumors. The hydrogels, specifically, offer advantages like flexibility and porosity, and mimics the properties of the extracellular matrix of the central nervous system. These factors make them an ideal scaffold for drug delivery through the blood-brain barrier and tissue regeneration (using stem cells). Thus, the use of biomaterials as suitable matrix for therapeutic purposes has emerged as a promising area of neurosciences. In this review, we describe the application of biomaterials, and the current advances, in treatment of statistically common neurological disorders.

Alopecia is a common problem that affects almost every age group and is considered to be an issue for cosmetic or psychiatric reasons. The loss of hair follicles (HFs) and hair caused by alopecia impairs self-esteem, thermoregulation, tactile sensation and protection from ultraviolet light. One strategy to solve this problem is HF regeneration. Many signalling pathways and molecules participate in the morphology and regeneration of HF, such as Wnt/β-catenin, Sonic hedgehog, bone morphogenetic protein and Notch. Non-coding RNAs (ncRNAs), especially microRNAs and long ncRNAs, have significant modulatory roles in HF development and regeneration via regulation of these signalling pathways. This review provides a comprehensive overview of the status and future prospects of ncRNAs in HF regeneration and could prompt novel ncRNA-based therapeutic strategies.
The TNF-α/TNFR2 Pathway: Targeting a Brake to Release the Anti-tumor Immune Response
Authors: Moatti Audrey , Cohen José L.
Published: October 2021

Newly discovered anti-cancer immunotherapies, such as immune checkpoint inhibitors and chimeric antigen receptor T cells, focus on spurring the anti-tumor effector T cell (Teff) response. Although such strategies have already demonstrated a sustained beneficial effect in certain malignancies, a substantial proportion of treated patients does not respond. CD4+FOXP3+regulatory T cells (Tregs), a suppressive subset of T cells, can impair anti-tumor responses and reduce the efficacy of currently available immunotherapies. An alternative view that has emerged over the last decade proposes to tackle this immune brake by targeting the suppressive action of Tregs on the anti-tumoral response. It was recently demonstrated that the tumor necrosis factor alpha (TNF-α) tumor necrosis factor receptor 2 (TNFR2) is critical for the phenotypic stabilization and suppressive function of human and mouse Tregs. The broad non-specific effects of TNF-α infusion in patients initially led clinicians to abandon this signaling pathway as first-line therapy against neoplasms. Previously unrecognized, TNFR2 has emerged recently as a legitimate target for anti-cancer immune checkpoint therapy. Considering the accumulation of pre-clinical data on the role of TNFR2 and clinical reports of TNFR2+Tregs and tumor cells in cancer patients, it is now clear that a TNFR2-centered approach could be a viable strategy, once again making the TNF-α pathway a promising anti-cancer target. Here, we review the role of the TNFR2 signaling pathway in tolerance and the equilibrium of T cell responses and its connections with oncogenesis. We analyze recent discoveries concerning the targeting of TNFR2 in cancer, as well as the advantages, limitations, and perspectives of such a strategy.
