Published: November 2020

The leaf area index (AFI) is an important variable when evaluating the growth, development and possible productivity of a crop. The objective of this article was to determine mathematical models that allow estimating the leaf area of tobacco from measurements of dimensions of length and width of tobacco leaves. The experimental design used was in blocks with four replications and two planting times. The treatments consisted of five commercial cultivars of Virginia type tobacco and Burley type. Of which the leaves were detached from the stem, and these leaves were fractionated in limbo and petiole. Its leaves were 10 models were obtained to estimate the leaf area of tobacco. All the models presented a significant test to estimate the leaf area. The power and quadratic models presented values of determination coefficients higher than linear models. It had the best results with the nonlinear power and quadratic model, using the squared width multiplied by length. Therefore, the measurements of the leaf area of tobacco can be estimated from potential, linear and quadratic equations with good precision. The models that use linear squared width measurements multiplied by leaf limbo length satisfactorily estimate the leaf area of tobacco.

Published: November 2020

This research aims to analyze the degradation of urea in its storage process, observing the environmental conditions of the storage building and also the storage time. In order to carry out such analysis, a field experiment with a completely randomized design (CRD), 3 × 4, was set up, with eight 50 kg bags divided in four different locations, being a shed, an underground basement, and two reduced models built in wood, where one received thermal input minimization treatments and the other with simplified coverage and closings. Within the four environments, temperature (DBT) and temperature (WBT) were measured, where it was possible to obtain the relative humidity values enabling thus crossing the internal climatic data with the process of urea degradation in storage for a period of three months. To analyze urea degradation, the analytical manual of fertilizers of the Ministry of Agriculture (MAPA) was used. The analyses of the physicochemical parameters of nitrogen content, density, humidity, total bag weight, and also granulometry were carried out monthly. The data were validated by one (ANOVA) and Tukey test with 5% probability of error. The results show that the environments with higher temperatures had a higher volatilization of nitrogen, the losses reached about 13% during the evaluated period. Losses of up to 5.3% of the density of the analyzed samples were also observed. In relation to the initial weight of the bags, losses totaled a reduction of 1.5%. It was also possible to conclude that the lowest losses were recorded in places where there was greater ventilation during the day, where the thermal inertia of the building dissipated.

Published: November 2020

A refocus on agriculture is considered a pertinent resort for the youths because it is generally believed to be a panacea for sustainable development in any nation. To help generate suitable policies to encourage youth farmers to be involved in agricultural activities, the study analysed factors that influence youth farmers’ participation in agricultural activities in Akwa Ibom State, Nigeria.

Through a list of farmers obtained with the assistance of Akwa Ibom State Agricultural Development Programme, 120 youth farmers were randomly selected for the study using simple random sampling technique. The study used descriptive and inferential tools to analyse information collected. The majority (59.2%) of youth farmers were male and 42.5% were between the ages of 36-39 years. Only 8.3% had access to credit. About 71% of the youth farmers were involved in on-farm activities and only 29.2% in both on- and off-farm activities. The major determinants of youth agricultural activities were household size and membership of social organizations. The state government and other relevant agencies and organizations should create platforms to educate youth farmers on the need for more involvement and diversification in their agricultural livelihood strategies.

Published: November 2020

This research was aimed to develop student vlog for community communication through social lab under the ECT Vlog project. In this study, a social lab consists of 3 communities near King Mongkut’s University of Technology Thonburi. Other objectives of this study were to determine the quality of the media and activities in this research, to evaluate the perception and the satisfaction of the sampling group towards the student vlog under the ECT Vlog project which was held in the second semester of the academic year 2019. The tools in this study consisted of questionnaires for the quality and the media presentation, the perception assessment form, and the satisfaction questionnaire. The sampling group in this study consisted of 100 followers of the ECT Vlog facebook page who had watched 12 student vlog video clips and were willing to participate in this research. They were chosen using purposive sampling method. The research results have shown that the researchers created 12 Student Vlog video clips for community communication through social lab with 3 communities near King Mongkut’s University of Technology Thonburi. The team of creators consisted of the researchers and undergraduate students from the ETM 358 Marketing Communication course. The team analyzed, designed, developed, implemented and evaluated the video clips according to the ADDIE Model which consists of 5 steps. The team analyzed the data, designed the contents and developed 12 student vlog clips and then asked 3 experts in contents and 3 experts in media presentation to evaluate the quality of the video clips. It was found that the quality of contents was at a very good level ( \hat{x} = 4.61, S.D = 0.38) and that the quality of media presentation was at a very good level ( \hat{x}= 4.62, S.D = 0.43). Afterwards, the researchers distributed the student vlog clips on the ECT Vlog facebook page and assessed the perception of the sampling group. It was found that their perception was at a high level ( \hat{x} = 4.50, S.D = 0.58). The sampling group expressed a high level of satisfaction towards the student vlog (\hat{x} = 4.43, S.D = 0.67), confirming the research hypotheses. It can be concluded that the development of student vlog for community communication through social lab was of good quality and that it could be used in other contexts.
The Choice between Renewables and Non-renewables: Evidence from Electricity Generation in 29 Countries
Authors: Nguyen Jeremy , Valadkhani Abbas , Hajargasht Gholamreza
Published: November 2020

We examine how per capita income and relative fossil fuel prices influence the use of non-renewables (oil, coal and natural gas), nuclear, hydroelectric, and other renewables in electricity generation. Panel regressions are estimated using the fully modified ordinary least squares method and data across 29 countries (1985-2017).We include both developed and developing economies whose classification status is allowed to vary during the sample period depending on per capita income.Results suggest that oil prices play a dominant role in boosting the use of renewables, while gas serves as a transition fuel. For developing nations, income is a significant constraint in the use of renewables, while coal and gas prices do not significantly influence the use of hydro and nuclear. This finding supports a shift away from the exclusive use of pricing mechanisms towards set targets linked to per capita income to encourage the use of renewables in developing economies.

Authors: Jahn Silke , Liu Aizhen , Dimitrov Mihail , Mazo Michail , Jürgen Friedrich , Matthias Krauss
Published: November 2020

In this paper an approach of using contextual information for structuring and displaying menus on small devices will be discussed, based on the implementation of a game for mobile games. CitizenMOB is a location-based, multiplayer, never-ending society-driven strategic mobile game that has been developed in order to understand today's possibilities and challenges in the design of complex games for mobile phones. Integrating a context-aware navigation and adaptive menu structure is an attempt not only to reflect the effect of new contexts of use on human-computer-interaction, it is also meant to overcome usability problems that occur when limitations of small screens are combined with complex rules and massive options in the next generation of rich mobile applications.
MATCHING SEMANTICALLY DESCRIBED WEB SERVICES USING ONTOLOGIES
Authors: Christensen Kim , Olesen Thorbjørn Højgaard , Thomsen Lone Leth
Published: November 2020

The theme for this article is Semantic Web Services. The motivation is the propagation of web services and the demand for dynamically exchanging web services in business processes (BPs). To achieve such dynamic exchange, it is necessary to be able to easily find web services that match a given set of requirements. Such requirements are best described with semantics, so it is necessary to develop a semantic UDDI repository (from now on denoted Sem-UDDI) for publishing of and searching for semantically described web services. Sem-UDDI is UDDI V2 compliant and uses a common interface based on UDDI categoryBags for publishing both OWL-S and WSDL-S described web services, and has a similar interface for searching. In order to sort the returned web services with respect to the search requirements, Sem-UDDI uses match score calculation rules based on commonalities between object properties in an OWL ontology concept hierarchy. Sem-UDDI is implemented as a layer to be put on top of a conventional UDDI repository, which gives companies the possibility of getting semantic functionality, while conti-nuing to use their existing UDDI repository.
THE USE OF BUSINESS RULES FOR THE SPECIFICATION OF DYNAMIC ASPECTS OF IS
Authors: Kapočius Kęstutis , Danikauskas Tomas
Published: November 2020

In the paper Output driven Information systems (IS) requirements specification method (ODRES) is overviewed emphasizing the problems of recording certain requirements. It is suggested that the method can be extended with business rules recording capabilities. Business rules-based requirements specification method is used to extend ODRES by incorporating method’s rules submodel into an ODRES metamodel in order to support non-structural business rules as additional knowledge about static and dynamic aspects of IS. Presented extension of ODRES concerns only the specification of dynamic aspects of IS. BRS RuleSpeak, which is the basis for a suggested rules submodel, is also overviewed in the paper and the benefits of the extension are outlined.
COMPARING GOAL-MODELLING TOOLS WITH THE RE-TOOL EVALUATION APPROACH∗
Authors: Matulevičius Raimundas , Heymans Patrick , Sindre Guttorm
Published: November 2020

Goal modelling usually takes place during the early information systems development phase known as requirements engineering (RE). RE is a key factor for project success where a good tool support is necessary. Several goal-modelling tools exist and several approaches can be used to evaluate them. In this paper, we report on an experiment to evaluate two goal-modelling tools - KAOS/Objectiver and i*/OME. We use an RE-tool evaluation approach (R-TEA) in order to determine which of the tools is better at supporting the creation of goal models. It turns out that KAOS/Objectiver apparently offers better model creation support but the quality of the resulting models is more dependent on situational language characteristics such as the focus on early (vs late) requirements.
ITERATED TABU SEARCH: AN IMPROVEMENT TO STANDARD TABU SEARCH
Authors: Misevicius Alfonsas , Lenkevicius Antanas , Rubliauskas Dalius
Published: November 2020

The goal of this paper is to discuss the tabu search (TS) meta-heuristic and its enhancement for combinatorial optimization problems. Firstly, the issues related to the principles and specific features of the standard TS are concerned. Further, a promising extension to the classical tabu search scheme is introduced. The most important component of this extension is a special kind of diversification mechanism. We give the paradigm of this new improved TS strategy, which is called an iterated tabu search (ITS). ITS was applied to the difficult combinatorial optimization problems, the traveling salesman problem (TSP) and the quadratic assignment problem (QAP). The results of the experiments with the TSP and QAP show the high efficiency of the ITS strategy. The outstanding performance of ITS is also demonstrated by the fact that the new record-breaking solutions were found for the hard QAP instances - tai80a and tai100a.

VISUALIZATION OF FRINGES IN TIME AVERAGED MOIRE PATTERNS
Authors: Saunorienė Loreta , Ragulskis Minvydas
Published: November 2020

Time averaging interferometry is an experimental technique widely applied in different areas of optical engineering. Typical example is an application of time averaging techniques for the analysis of fringes produced by a moiré grating formed on the surface of oscillating elastic structure. Unfortunately, time averaged moiré produces blurred images. Therefore, special digital image filtering is to be used for highlighting the pattern of time averaged fringes. Such a procedure is essential for the investigation of dynamical systems with non-harmonic motion as the produced moiré pattern is particularly blurred. This paper proposes some techniques for the sharpening of fringes in time averaged moiré patterns.
Fuzzy-Logic-Based Adaptive Proportional-Integral Sliding Mode Control for Active Suspension Vehicle Systems: Kalman Filtering Approach
Authors: Zare Kazem , Mardani Mohammad Mehdi , Vafamand Navid , Khooban Mohammad Hassan , Shamsi Sadr Sajjad , Dragičević Tomislav
Published: November 2020

This paper deals with the problem of synthesizing a fuzzy-logic-based adaptive proportional-integral sliding mode control (FAPISMC) for active suspension systems based on Kalman filtering approach. To improve the performance of the controller and eliminate the effect of the chattering, the switching input is designed based on the fuzzy-logic-based approach with a minimum number of rules. In order to facilitate the stability analysis, the estimation of the state variables is used in designing the sliding surface platform. Furthermore, the gain of the controller is updated by an adaptive law to avoid any pre-knowledge of the disturbance amplitude. Subsequently, the proposed approach is more implementable in real-world processes. Finally, in order to illustrate the effectiveness and merits of the proposed approach, a suspension system is considered and simulated by the real-time hardware-in-the-loop (HiL). In this example, a quarter-car model of suspension systems is considered. Then, the obtained real-time results are compared with the linear quadratic regulator approach.
The Placement of Virtual Machines Under Optimal Conditions in Cloud Datacenter
Authors: Gharehpasha Sasan , Masdari Mohammad , Jafarian Ahmad
Published: November 2020

Nowadays cloud computing is progressing very fast and has resulted in advances in other technologies too. Cloud computing provides quite a convenient platform for millions of users to use computing resources through the internet. Cloud computing provides the possibility of only concentrating on business goals instead of expanding hardware resources for users. Using virtualization technology in computing resources results in the efficient use of resources. A challenging work in virtualization technology is the placement of virtual machines under optimal conditions on physical machines in cloud data centers. Optimal placement of virtual machines on physical machines in cloud data centers can lead to the management of resources and prevention of the resources waste. In this paper, a new method is proffered based on the combination of hybrid discrete multi-object sine cosine algorithm and multi-verse optimizer for optimal placement. The first goal of the proposed approach is to decrease the power consumption which is consumed in cloud data centers by reducing active physical machines. The second goal is to cut in resource wastage and managing resources using the optimal placement of virtual machines on physical machines in cloud data centers. With this approach, the increasing rate of virtual migration to physical machines is prevented. Finally, the results gained from our proposed algorithm are compared to some algorithms like the first fit (FF), virtual machine placement ant colony system (VMPACS), modified best fit decreasing (MBFD).
Sein und „Sein“
Authors: Cornejo José Pedro
Published: November 2020

Die vorliegende Untersuchung zur Ontologie in Martin Heideggers „Sein und Zeit“ führt zur Entdeckung einer Uneindeutigkeit im Gedankenmodell des Philosophen und zur Definition einer zweifachen Bedeutung vom Begriff Sein. Es wird dargelegt, dass sich aus Heideggers Versuch, den Sinn des Seins zu entschlüsseln, keine eindeutige Antwort ergeben kann, da der Mensch sein Dasein als Möglichkeit begreift, und dies zum einen im Sinne einer Projektion, zum anderen in dem einer Fähigkeit. Ersteres lässt sich als Sinnhorizont (Sein), zweiteres als Endlichkeit der Existenz („Sein“) begreifen. Der fundamentale Unterschied dieser beiden Prinzipien bildet die Grundlage jeder wissenschaftlichen Untersuchung und der Philosophie selbst als schönster Tochter der menschlichen Freiheit.
Dramaturgies of Theatrical Imagination
Authors: Woisnitza Mimmi
Published: November 2020

The study examines an aspect of German theatre history that is relevant also in the context of the current engagement with theatrical phenomenology and reception. The historical, discursive, and political situating of canonical dramas shows that "dramatic theater" itself is to be regarded as part of cultural and theatrical practice. The dramas of Lessing and Kleist operate with a broad spectrum of theatrical techniques (such as teichoscopy, ekphrasis, masquerade and mise en abyme) that seek to promote, shape and direct the imaginative participation of their implied audiences. In addition to presenting imagination on the plot level, the dramas reflect their own medial status by staging the consequences and the reformation of "false" imaginative investments.

Moving a Unique Collection to Storage: Improving Access Now and Later
Authors: Maddox Abbott Jennifer A.
Published: November 2020

The University of Illinois at Urbana-Champaign Library collected college and university publications (the C-Collection) for several decades without allocating the resources to catalog them. A project to make these items discoverable by patrons was initiated, and tens of thousands of items were added to the online catalog. These items were physically stabilized and transferred to the library’s high-density storage facility. A portion of the collection was also digitized, providing electronic access. Although circulation trended downward, there was no clear indication that materials were less accessible in high-density storage, and new items were discovered that had not previously circulated. Digital surrogates of library material clearly allowed the library to reach a much larger audience, and ideal storage conditions to preserve physical materials long-term combined with electronically available copies appear to be an ideal means for providing greater access while preserving content.

In the introduction, the authors of this concise work state that their aim is to present the basics of linked data specifically to librarians “whose background may not be traditionally considered ‘technical’” (x). They state that the book “is a great primer on linked data basics, it is not an exhaustive dive into the topic, nor is it intended to make you an expert” (xi). To a large degree, the authors meet these objectives, at least to this reviewer who is not of a technical background.
Book Review: The Role of the Electronic Resources Librarian
Authors: Murray Jennifer
Published: November 2020

The eight chapters covered in this text give a detailed history about how the role of electronic resource (e-resource) librarians (ERLs) has evolved over the past several decades as libraries have shifted to an online environment. It covers the challenges faced from 1992 when the ERL title was first used, to 2019 where academic libraries are still a hybrid of print and electronic materials. The book is organized into eight chapters with three appendixes. The introduction gives a brief overview on the development of ERLs and a clear synopsis of chapters, which are a nice progression of how the ERL position has developed since the 1990s; how it has been represented in organizational structures across academic libraries; how it has handled a variety of obstacles (technology, expanding skill sets, budget constraints, etc.); and how it maps to current trends in managing e-resources.
Estímulos geradores da raiva em estudantes com deficiência intelectual sob a perspectiva da Educação Emocional
Authors: Dantas Taísa Caldas
Published: November 2020

Este artigo tem como objetivo analisar os principais estímulos geradores da emoção da raiva em estudantes com deficiência intelectual a partir dos princípios da Educação Emocional. Diante de uma realidade de preconceito e exclusão vivenciada pelas pessoas com deficiência, o que afeta diretamente as suas emoções, a emoção da raiva é comumente vivenciada por esse grupo social, muitas vezes, de forma inconsciente e afetando diretamente seu bem-estar. Nesse contexto, a Educação Emocional surge como ferramenta pedagógica que deve ser incluída na escola, uma vez que oferece a possibilidade de o sujeito educar-se emocionalmente. O argumento central que norteia este estudo é que a emoção da raiva, quando vivenciada de maneira saudável através da Educação Emocional, pode contribuir para a superação de situações de vulnerabilidade que marcam a vida das pessoas com deficiência. Esta pesquisa adere à abordagem qualitativa e foi realizada por meio da observação direta e da entrevista semiestruturada, com 27 jovens com deficiência intelectual da Educação de Jovens e Adultos (EJA). Os resultados deste estudo apontam a importância da vivência da raiva de maneira saudável e consciente através dos princípios da Educação Emocional, pois esta emoção pode proporcionar motivação para o rompimento de situações de vulnerabilidade em pessoas com deficiência.Palavras-chave: Educação Emocional; Raiva; Deficiência Intelectual.

Sociological Analysis of the Commercial Hunting on the Lands of Small-Numbered Indigenous Peoples of the North in the Arctic Zone of the Sakha Republic Republic (Yakutia)
Authors: V. Velichenko Valery , N. Sleptsov Anatoly
Published: November 2020

The article presents the results of the analysis of commercial hunting of the most typical communities of small indigenous peoples of the North of Russia living in the Arctic zone of Yakutia, for which hunting largely determines the life quality. For the analysis, statistical data and internal hunting materials were used with the participation of the article authors. In preparing this article, we used statistical data and materials from the Yakutia Department of Hunting Management, as well as stock materials from the Institute. We used statistical methods to process the materials. For the first time, the materials of the intra-economic hunting arrangement conducted in the areas assigned to small peoples are analyzed. For the first time, the article provides data on the history of establishing hunting grounds in Yakutia as part of all-Russian activities. The article provides the results of foreign researchers' studies dedicated to the issue of framing and maintaining the traditional lifestyle of indigenous peoples of the North. Based on the analysis of the structure of commercial production, it is demonstrated that hunting trends are adapted to the extreme weather and climatic conditions of the Arctic and defined by the wildlife species that inhabit these regions. Backed by retrospective analyses, considerable changes in the structure of commercial production are illustrated. These are linked to the decrease in numbers of one of the populations of wild reindeer and the decreasing demand for natural fur, factors that have reduced the importance of traditional hunting in the lives of the region’s ethnic groups. It is revealed that the forecast of large-scale development of mineral resources in the Arctic regions of Yakutia demands that preventive measures be taken to protect natural resources that are the foundation for the traditional crafts of the indigenous peoples of the North.

Shaping the Other in the Standardization of English
Authors: Ruano-García Javier
Published: November 2020

This paper explores the other side of standardization by looking at one of the early modern regional varieties of English that remained outside the “consensus dialect” (Wright, 2000: 6). Drawing on Agha’s (2003) framework of enregisterment, I examine a selection of literary representations of the ‘northern’ dialect that are now included in The Salamanca Corpus (García-Bermejo Giner et al., 2011–), as well as contemporary lexicographical evidence on northern words. My aim is to provide a window into contemporary ideas that saw and constructed the North as the ‘other’, whilst showing, as a result, that such views were immediately relevant to how the dialect and their speakers were imagined and represented alongside the emerging standard. To do so, I undertake a twofold quantitative and qualitative analysis of the evidence to identify the repertoire of forms that were associated with the dialect and the values attributed to such forms.
Standardization Process in its Final Stages
Authors: Kytö Merja , Walker Terry
Published: November 2020

This study concerns the development of the determiners mine/my and thine/thy in the Early Modern English period. The -n forms had essentially been ousted before words starting with consonants over the Middle English period, and over the subsequent centuries, these forms also fell into disuse before words starting with initial vowels and h. While the rise of the n-less variants has been the object of several previous studies, the present investigation aims at accounting for the fate of the declining n-variants in the Corpus of English Dialogues 1560–1760, a data source comprising speech-related texts. We look into the chronological stages of development for the declining mine and thine forms, the genres that maintained these forms longest, and the speaker groups that were the last to use the forms. Comparisons are made with the results obtained in previous studies on mine/my and thine/thy variation.

Robust biomarkers of aging have been developed from DNA methylation in humans and more recently, in mice. This study aimed to generate a novel epigenetic clock in rats—a model with unique physical, physiological, and biochemical advantages—by incorporating behavioral data, unsupervised machine learning, and network analysis to identify epigenetic signals that not only track with age, but also relates to phenotypic aging. Reduced representation bisulfite sequencing (RRBS) data was used to train an epigenetic age (DNAmAge) measure in Fischer 344 CDF (F344) rats. This measure correlated with age at (r = 0.93) in an independent sample, and related to physical functioning (p=5.9e-3), after adjusting for age and cell counts. DNAmAge was also found to correlate with age in male C57BL/6 mice (r = 0.79), and was decreased in response to caloric restriction. Our signatures driven by CpGs in intergenic regions that showed substantial overlap with H3K9me3, H3K27me3, and E2F1 transcriptional factor binding.

Background

Rare single nucleotide polymorphisms (SNPs) are likely to be a crucial genetic factor for human diseases, including cancer. rs78378222 is rare SNP in 3′-untranslated region (UTR) of TP53 gene leading to disturbance of 3′-end mRNA processing. The frequency of rs78378222 varies in several studied populations. The meta-analysis of 34 genome-wide association studies indicated that rs78378222 was significantly associated with an increased risk of cancer overall. Bioinformatic analysis indicates that somatic loss of the protective A allele of rs78378222 occurs in the tumor tissue of some malignant. The goal of the current study is to document the rs78378222 prevalence and evaluate the copy loss status of the protective allele A in the tumor tissue of patients with diffuse large B-cell lymphoma (DLBCL).

Methods

Total DNA was isolated from FFPE-samples and peripheral blood of patients with DLBCL and comparable in age and sex controls. rs78378222 genotyping was performed by the PCR-RFLP method using restriction endonuclease HindIII. Direct Sanger’s sequencing was used to confirm the presence of C allele of the rs78378222. The search for TP53 gene mutations was carried out by Sanger’s direct sequencing method, according to the IARC protocol.

Results

The result of genotyping of 136 DNA samples from DLBCL tumor tissue suggested that frequency of the rs78378222 was 11/136 (8.1%). Rare allele C frequency was 11/272 (4.2%). A total of 5/11 DLBCL rs78378222 heterozygous samples had the heterozygosity loss in the TP53 gene. Only one of these cases was combined with TP53 gene mutations which have proven oncogenic potential—p.Arg196Gln, other four cases have not mutations in the coding regions of gene.

Conclusions

At the stages of DLBCL initiation or progression a loss of the protective allele A of rs78378222 occurs. Further efforts are needed to study possible molecular mechanisms underlying somatic alterations in DLBCL in this region of the TP53 3′-UTR as well as functional studies to illustrate how the presents of rs78378222 may affect tumor progression of lymphoma.
Self‐Regulating Contact Lenses with the Patterning of a Photochromic Layer Based on Wettability Contrast
Authors: Kim Se‐Um , Lee Sang Hyun , Kim Kitae , Na Jun‐Hee
Published: November 2020

Contact lenses that change between the transparent state and the colored state in response to the UV light, to play a supplementary role in the light adaptation of the human visual system, are demonstrated. The capability of light regulation is realized by the conformally coated photochromic layer that comprises the blend of spiropyran dyes and the biocompatible polymer matrix to embed them. The wettability contrast on the surface of contact lenses, which is produced from the transfer printing of siloxane oligomers, allows for selective patterning of the photochromic layer on the iris part. By designing the ratio of blended dyes, the light regulation across the wide visible range is achieved. Proposed self‐regulating contact lenses exhibit high durability and reliability while working in wet conditions, showing their possibilities in practical application.

Range‐separated hybrid (RSH) functionals have been recently used to overcome the tendency of traditional density functional theory (DFT) calculations to overestimate the conductance of molecular junctions. Non‐equilibrium conditions are addressed following non‐equilibrium Green's function (NEGF) formulation with RSH functionals to study negative differential resistance (NDR) in molecular junctions of oligo phenylene ethylene derivatives linking gold electrodes. It is shown that the RSH‐NEGF calculations indicate NDR onset bias that agrees well with measured trends, associate NDR to orbital localization at the drain contact, and analyze the role of junction asymmetry in NDR. The RSH‐NEGF results are also compared with alternative DFT‐NEGF combinations to highlight the importance of basing the computational study on a functional that achieves physically significant frontier orbitals. Finally, the effects of thermally accessible molecular fluctuations to enhance the NDR conductance drop are also discussed.

Weed communities may potentially reduce row‐crop yields resulting in a loss of revenue for producers. Studies have reported a decrease in the efficacy of chemical methods of weed control due to increased weed resistance. With the goal of reducing reliance on chemical weed control and promoting sustainable crop production in mind, we evaluated different winter cover crop (CC) types (single‐, double‐, and multi‐species) and CC planting methods (broadcasting vs. drilling) on CC and weed groundcover and row‐crop yield in a no‐till corn (Zea mays L.)–soybean [Glycine max (L.) Merr.] rotation system in Tennessee from 2013 to 2017. Our results showed that winter CC reduced spring weed ground coverage by 64–76% compared with winter fallow with no herbicide application. A five‐species CC mixture increased soybean yields by 6 to 8.5% across seeding method treatments compared with other CC treatments and winter fallow. This yield increase was more visible in a drought year. Corn, grown in years with normal weather patterns, did not show a yield response to CC types. From this study, cover cropping was found to be an effective strategy for weed control compared with leaving the field fallow without herbicide application following row‐crop harvest; however, no consistent species‐specific trends were observed on weed suppression and row‐crop yield. Future research should focus on understanding CC species composition and biomass production in double‐ and multi‐species mixtures from this field experiment to draw robust conclusions on agronomic responses of individual CC species and planting methods.
Autosomal‐dominant WFS1‐related disorder—Report of a novel WFS1 variant and review of the phenotypic spectrum of autosomal recessive and dominant forms

Wolfram syndrome was initially reported as an autosomal recessive (AR), progressive neurodegenerative disorder that leads to diabetes insipidus, childhood onset diabetes mellitus (DM), optic atrophy, and deafness (D) also known as DIDMOAD. However, heterozygous dominant pathogenic variants in Wolfram syndrome type 1 (WFS1) may lead to distinct, allelic conditions, described as isolated sensorineural hearing loss (SNHL), syndromic SNHL, congenital cataracts, or early onset DM. We report a family with a novel dominant, likely pathogenic variant in WFS1 (NM_006005.3) c.2605_2616del12 (p.Ser869_His872del), resulting in cataracts, SNHL, and DM in a female and her mother. A maternal aunt had cataracts, DM, and SNHL but was not tested for the familial WFS1 mutation. Both the mother and maternal aunt had early menopause by age 43 years and infertility which may be a coincidental finding that has not been associated with autosomal dominant AD WFS1‐related disorder to the best of our knowledge. Screening at risk individuals in families with the AR Wolfram syndrome, for DM, SNHL, and for cataracts is indicated.

Aim

Anaphylaxis is a severe, life‐threatening, generated or systemic reaction, and biphasic reaction could occur in some cases. We investigated the clinical course of anaphylaxis in our hospital and studied the relationship between biphasic reactions and the symptoms and treatments for predicting the onset of biphasic reactions.

Methods

We retrospectively reviewed the medical records of 120 patients with anaphylaxis who were admitted to our hospital from the emergency department during April 2008–October 2015.

Results

The incidence of biphasic reactions of anaphylaxis in our hospital was 10.8% (13 patients) without significant difference when compared with that in previous reports. Regarding the development of biphasic reactions, symptoms, the number of systems of symptoms and severity of the initial reaction, and treatment with adrenaline and corticosteroid were not clearly related with biphasic reaction. Use of adrenaline in the initial treatment was approximately 60%. Of the 13 biphasic reactions, 11 (84.5%) were as equal/mild as the original symptoms.

Conclusion

This study could not show the factors predicting the onset of biphasic reactions. Further prospective and nationwide studies are required to research biphasic reactions.

Published: November 2020

In this study, a thin layer with a thickness of about 120 μm of poly(caprolactone) (PCL) was fabricated by electrospinning method. Then, a fibrous nanocomposite composed of PCL/silk fibroin/strontium carbonate (PCL/SF/SrCO3) was electrospun on the prepared layer. Then, they were characterized. The mechanical properties, water uptake, degradation rate, wettability, porosity, and bioactivity of the electrospun membrane were scrutinized in vitro. Cytotoxicity of the samples was assessed by using osteoblast‐like cells (SAOS‐2) and L929 fibroblasts. Moreover, the cell adhesion, alkaline phosphatase (ALP) activity, and calcium deposition through alizarin red staining were conducted. Results revealed that the bilayer structure doubled the optimum mechanical properties and the addition of SrCO3 up to 15%–20% increased ALP activity, calcium deposition, and bioactivity. According to the results, the nanofibrous bilayer membrane containing 20 wt% SrCO3, 20 wt% SF, and 60 wt% PCL was chosen as the optimum sample. Therefore, this membrane could be applied in guided bone regeneration (GBR).
Using Chemical Inventory Data to Prepare Against Source Water Contamination

Published: November 2020

Key Takeaways

If community water systems can easily access information about hazardous chemical storage in their source water protection area (SWPA) and know how to make full use of the data, they stand a better chance of sufficiently preparing for source water emergencies.

Required under the Emergency Planning and Community Right‐to‐Know Act, annual Tier II reports contain valuable information about specific hazardous chemicals that are stored or used in SWPAs.

Provisions in America's Water Infrastructure Act of 2018 give community water systems a legal right to Tier II hazardous chemical inventory data for facilities in their SWPA, which can be used to promote comprehensive source water protection planning.

The quantification of the circulating dehydroepiandrosterone sulfate (DHEAS) might be of diagnostic help for several diseases. For the DHEAS quantification, LC/ESI–MS/MS has the advantage of a high specificity compared with immunoassay, whereas LC/ESI–MS/MS has room to improve the analysis throughput. One of the promising solutions to enhance the analysis throughput is sample‐multiplexing in the same injection, which can reduce the total LC/ESI–MS/MS run time. In this study, a quadruplex LC/ESI–MS/MS method was developed to quantify DHEAS in four different serum samples in a single run. After the four samples were separately deproteinized and derivatized with one of four Girard reagents (Girard reagent T, P and their isotopologs), the resulting samples were mixed, then injected into the LC/ESI–MS/MS. The applicability and advantage of the developed method were evaluated based on the analysis of nine batches of serum samples from healthy subjects (total 36 samples). The limit of quantitation was 0.050 μg/ml, which was sensitive enough for clinical laboratory use. The method was precise (intra‐ and inter‐assay RSDs ≤ 3.6%), accurate (94.4–108.1%) and robust for the matrix effects. The analysis time was also shortened by about 60% for 36 samples by the introduced method compared with the conventional method.

The litigation between the University of California, Los Angeles and Under Armour demonstrates that even the most attractive and economically lucrative agreements can quickly deteriorate into legal wrangling in both federal and state courts. Indeed, only a few years ago, the parties announced a groundbreaking deal reportedly in the range of $280 million in cash and products during a 15‐year period. That arrangement arose after similar agreements for major programs with other manufacturers escalated in value.

There are numerous traits and skills needed to lead a team. However, when we lead through a crisis that could ultimately shift how we do business, inherent traits woven through a leader keep us moving forward through rapid change and nurture our team in the process. Whether we like it or not, life is wrapped in change, and it is here to stay. Learning new ways of doing things draws us out of our comfort zones. But when change is thrust upon us, pushing us out of our comfort zone, our response is our choice. As leaders dare to step out of their comfort zones and teach their team the advantages of making bold but responsible decisions, lasting excellence can be secured for our institutions.
