A logarithmic sprayer was suggested about 70 years ago, but it has not yet been seriously used in research and development, and subsequent registration of plant protection products. Logarithmic sprayers have resorted to mere demonstration experiments to show end users and others how plant protection products work. Fitting dose-response curves in field experiments, however, generates much essential information, e.g., extraction of various effective field rate levels (e.g., ED20 , ED50 , and ED80 ). One of the reasons for it rarely being used in the registration of plant protection products is that the dose-response curve regression was hitherto difficult to fit; the registration requirement solely focuses on analyses of variance...

Antibiotic resistance and tolerance remain a major problem for the treatment of staphylococcal infections. Identifying genes that influence antibiotic susceptibility could open the door to novel antimicrobial strategies, including targets for new synergistic drug combinations. Here, we developed a genome-wide CRISPR interference library for Staphylococcus aureus , demonstrated its use by quantifying gene fitness in different strains through CRISPRi-seq, and used it to identify genes that modulate susceptibility to the lipoglycopeptide dalbavancin...

Background: Over the past two decades, increasing numbers of women have served in the military, with women now comprising 17.3% of active-duty personnel and 21.4% of National Guard and reserves. During military service, women often incur painful musculoskeletal (MSK) injuries related to carrying heavy loads and wearing ill-fitting gear. While women may receive initial care for these injuries under the auspices of the Department of Defense (DoD), these injuries often linger and further treatment in required as women transition to Department of Veterans Affairs (VA) care...

BACKGROUND: Work-related musculoskeletal disorders are widespread among workers of informal small-scale enterprises. Specifically, lower back pain is a prevalent occupational health problem across various industries, including weaving factories. Lower back pain significantly impairs the functioning, performance, and productivity of weavers. However, information on the prevalence and associated factors of low back pain among weavers of Bahir Dar City and nationwide is scarce. Therefore, this study aimed to assess the prevalence and associated factors of lower back pain among weavers working in Bahir Dar City...

PURPOSE: This work presents a novel platform for stereo reconstruction in anterior segment ophthalmic surgery to enable enhanced scene understanding, especially depth perception, for advanced computer-assisted eye surgery by effectively addressing the lack of texture and corneal distortions artifacts in the surgical scene. METHODS: The proposed platform for stereo reconstruction uses a two-step approach: generating a sparse 3D point cloud from microscopic images, deriving a dense 3D representation by fitting surfaces onto the point cloud, and considering geometrical priors of the eye anatomy...

The term 'druggability' describes the molecular properties of drugs or targets in pharmacological interventions and is commonly used in work involving drug development for clinical applications. There are no current analogues for this notion that quantify the drug-target interaction with respect to a given target variant's sensitivity across a breadth of drugs in a panel, or a given drug's range of effectiveness across alleles of a target protein. Using data from low-dimensional empirical fitness landscapes composed of 16 β-lactamase alleles and 7 β-lactam drugs, we introduce two metrics that capture (i) the average susceptibility of an allelic variant of a drug target to any available drug in a given panel (' variant vulnerability' ), and (ii) the average applicability of a drug (or mixture) across allelic variants of a drug target (' drug applicability ')...

OBJECTIVES: Publicizing safety ratings of vehicles can motivate manufacturers to prioritize safety and help consumers choose safer vehicles, leading to safer fleets. The benefits of primary safety technologies that prevent crash occurrence are not currently incorporated in current ratings in a way that values their safety benefits consistently. We aimed to propose a method for assigning weights for each safety technology to account for established safety benefits using published effectiveness and prevalence from real-life data...

OBJECTIVE: Fitness influencers have become important digital health communicators with regard to influencing consumer health behaviours, such as physical activity. We investigate how working (out) with these new communicators can generate benefits for the fitness influencer, user health, and endorsed brands. Based on the source credibility, social identity theory, and gender congruity research, this paper aims to identify the main factors that affect users' attitudes toward the fitness influencer (influencer benefit), users' exercise intentions (user health benefit) and their purchase intentions (brand benefit), considering user and influencer gender...

Water pollution represents one of the most important problems affecting the health of living organisms, so it was necessary to work on the formation of active materials to get rid of pollutants. In this study, Titanium dioxide (TiO2 ) doping Zinc oxide (ZnO) nanocomposites were produced via simple sonication method at 500 Hz in ethanol medium. At different weight concentrations (2.5, 5, 7.5, and 10 %). The morphology, structure configuration, chemical bonding, crystalline phase, and surface properties of obtained nanocomposites were characterized via FESEM, BET, XRD, XPS, RAMAN and FTIR instrumentation...

BACKGROUND: Federal legislation still prohibits the cultivation, sale and consumption of cultivars of delta 9-tetrahydrocannabinol cannabis (>0.3%), however, as of November 2022, 39 states have legalized these products for medicinal consumption and 21 states have legalized for adult-use consumption. This state-by-state approach has produced a patch work of regulations that multi-state operators (MSO) must learn to navigate. Furthermore cannabis laboratories often lack the space and skill needed to perform method validations adding another layer of complexity...

A research-supported model to support schools' prevention of behavior problems and promotion of a positive school climate is school-wide positive behavior support (SW-PBS), in Scandinavia adapted into "positive behavior, interactions and learning environment in school" (PALS). Facilitators and barriers for achieving and sustaining a full implementation of PALS in a Swedish primary school context have not previously been studied. The purpose of this study was to explore school staff and administrators' experiences of implementing PALS in a municipal school district in the western region of Sweden...

While genome-wide association studies are increasingly successful in discovering genomic loci associated with complex human traits and disorders, the biological interpretation of these findings remains challenging. Here we developed the GSA-MiXeR analytical tool for gene set analysis (GSA), which fits a model for the heritability of individual genes, accounting for linkage disequilibrium across variants and allowing the quantification of partitioned heritability and fold enrichment for small gene sets. We validated the method using extensive simulations and sensitivity analyses...

Salmonella enterica is comprised of genetically distinct 'serovars' that together provide an intriguing model for exploring the genetic basis of pathogen evolution. Although the genomes of numerous Salmonella isolates with broad variations in host range and human disease manifestations have been sequenced, the functional links between genetic and phenotypic differences among these serovars remain poorly understood. Here, we conduct high-throughput functional genomics on both generalist (Typhimurium) and human-restricted (Typhi and Paratyphi A) Salmonella at unprecedented scale in the study of this enteric pathogen...

Existing emotion regulation research focuses on how individuals use different strategies to manage their own emotions-also called intra-personal emotion regulation. However, people often leverage connections with others to regulate their own emotions-interpersonal emotion regulation. The goal of the present studies was to develop a comprehensive and efficient scale-the Emotion Regulation Strategies Scale (ERSS)-to assess nine specific emotion regulation strategies that individuals use both intra-personally and interpersonally...

Quantum mechanics (QM)-driven 1 <u>H</u> <u>i</u>terative <u>f</u>unctionalized <u>s</u>pin <u>a</u>nalysis produces HifSA profiles, which encode the complete 1 H spin parameters ("nuclear genotype") of analytes of interest. HifSA profiles enable the establishment of digital reference standards (dRS) that are portable, FAIR (findable - accessible - interoperable - reusable), and fit for the purpose of quantitative 1 H NMR (qHNMR) analysis at any magnetic field...

Persistent water contaminants include a variety of substances that evade natural cleaning processes posing severe risks to ecosystems. Their adsorptive elimination is a key approach to safer attenuation. Herein we present the design and development of Prussian blue incorporated polypyrrole (PPY/PB) hybrid nanocomposite as a high-performance adsorbent for the elimination of malachite green (M.G.), isoniazid (INH) and 4-nitrophenol (4-NP) water contaminants. The nanocomposite synthesis was favored by strong dopant-polymer interactions, leading to a PPY/PB material with enhanced electro-active surface area compared to pristine PPY...

INTRODUCTION: Musculoskeletal disorders affect over a third of the UK adult population and are a common reason for sick leave from work. The aims of this study were to describe the reported provision of work participation support for adults with hand and upper limb conditions by UK hand therapists, and to identify potential training needs in this area. METHODS: A previous survey of the Australian Hand Therapy Association was adapted for the UK. The electronic questionnaire was distributed to members of the British Association of Hand Therapists...

Results from cultural evolutionary theory often suggest that social learning can lead cultural groups to differ markedly in the same environment. Put differently, cultural evolutionary processes can in principle stabilise behavioural differences between groups, which in turn could lead selection pressures to vary across cultural groups. Separating the effects of culture from other confounds, however, is often a daunting and sometimes intractable challenge for the working empiricist. To meet this challenge, we exploit a cultural border dividing Switzerland in ways that are independent of institutional, environmental and genetic variation...

UNLABELLED: Experience changes the tuning of sensory neurons, including neurons in retinotopic visual cortex, as evident from work in humans and non-human animals. In human observers, visuo-cortical re-tuning has been studied during aversive generalization learning paradigms, in which the similarity of generalization stimuli (GSs) with a conditioned threat cue (CS+) is used to quantify tuning functions. This work utilized pre-defined tuning shapes reflecting prototypical generalization (Gaussian) and sharpening (Difference-of-Gaussians) patterns...
