Authors: Tahir A. D , Alkali H. M , Saleh R. A
Published: July 2022

The study was conducted to analyze cost and return of sesame production in Hong L.G.A of
Adamawa State, Nigeria. Multi stage sampling technique was used to select fifty-seven sesame
farmers in the study area. Data were collected using structured questionnaire. Data were
analyzed using gross margin analysis and descriptive statistics. The results revealed labour
cost accounted for 68.1% of the total cost of production. Cost of fertilizer accounted for 20.3%,
cost of chemical accounted for 7.8% while cost of seed accounted for 3.8%. On the average, it
cost N 47,451.35/ha to cultivate sesame in the study area. An average of N 65,053/ha accrues
to farmers as gross income and N 17, 601.65 is left as gross margin. The result of constraints
faced by sesame farmers were lack of credit facility 94.7% which was ranked 1st, inadequate
fertilizer 93.0% which was ranked 2nd, lack of good road 82.5% which was ranked 3rd, poor
extension services 77.2% which was ranked 4th, problem of pest 71.9% which was ranked 5th,
problem of disease 70.2 which was ranked 6th, and high cost of production inputs 56.1% which
was ranked 7th. The study concludes that sesame production in the study area is profitable and
the major constraints faced by sesame farmers is lack of credit facility and inadequate
fertilizer. Therefore, it was recommended that government should support sesame farmers by
providing subsidized production inputs and farm credit and also government should strengthen
and increase extension services among farmers.
Determinants of Income Diversification Strategies among Smallholder Wheat Farmers in Jigawa State, Nigeria
Authors: Malami A , Umar S , Suleiman I
Published: July 2022

The study assessed the determinants of income diversification strategies among smallholder wheat farmers in Jigawa State. Primary data were collected from 255 smallholder wheat farmers in the study area selected using multi stage sampling procedure. The collected data were analysed using Logit regression, Simpson Diversification Index (SDI) and two stage least square regression analyses. The result revealed that non-farm income and number of income sources had significant positive relationship with income diversification. The two stage least square estimation with respect to Herfindahl Diversification Index (HDI) showed that age and years of education had positive significant relationship. The two stage least square estimation with respect to number of income share revealed that the number of income sources, age, farm size, frequency of extension contacts and years of education had significant positive relationship with per capita income. The major constraints to wheat production were limited production inputs (seed), pest and disease, low output price, lack of credit and timely preparation. Similarly, the effect of income diversification with reference to off farm income share showed that off farm income share, age and years of education had positive significant relationship. The study concluded that off farm income share and number of income sources were the most important determinants of income diversification and the major challenge to wheat production were limited access to right inputs, pest and diseases and low output prices. Thus, the study recommended that improving performance of determinants of diversification and linking farmers to better production and output markets as well as enlightening the farmers about pests and diseases control measures will improve the wellbeing of the farmers.

Seeking the Right Time for Venous Thromboembolism Prophylaxis Alerts
Authors: Hentzen Stijn , Hacker Sarah , Meyer Nathan , Kuperman Ethan
Published: July 2022

Background

Our institution used an automated provider alert for venous thromboembolism (VTE) prophylaxis. This alert had an option to “snooze,” generating a user-specific delay before repeat firing. Providers snoozed 67% of VTE alerts. Our aim was to decrease alert burden by 25% through lengthening the snooze delay.

Methods

This initiative was conducted at a tertiary care academic medical center using an integrated electronic health record. Data was collected with snooze delay time set at 1, 2 and 3 hours. Our primary outcome was the number of alerts per 100 admissions. Secondary outcomes included percentage of alerts snoozed, percent of patients receiving pharmacoprophylaxis, and percent of admissions satisfying VTE core measures.

Results

There was no change in alerts per 100 admissions (168 vs. 176, p=0.375) or percentage of patients receiving pharmacoprophylaxis (50.9% vs. 50.9%, p=0.997). There was a small reduction in snooze percentage (67.0% to 63.2%, p=<0.001) and a small increase in core measure satisfaction (86.0% to 88.0%, p=0.025). On post-hoc analysis, the intervention increased the median interval between same-patient, same-provider VTE alerts (3.4 to 8.3 hours). Internal medicine hospitalists were responsible for 22% of alerts, selecting snooze 78% of the time.

Conclusion

Increasing snooze delay time did not decrease alert burden. Manipulating alert parameters is unlikely to decrease alert burden without simultaneous changes in provider response culture.
51% of Local Music: Cultural Imperative and Legal Norm for the Development of the Music Industry in the Republic of Moldova
Authors: Badicu Iurie
Published: July 2022

The music industry in the Republic of Moldova is proxy to the global music industry, with similar problems and perspectives. The effi cient functioning of the local music industries of the European states is becoming current and increasingly evident in the theoretical and practical approaches of the researchers, musicians, as well as of the economic entities in the fi eld. In this sense, the local music industries have traveled, in the last 30 years, through similar and oscillating routes, with many challenges and few opportunities on the local dimension. Thus, the music industry of the Republic of Moldova yields, from a structural, functional and tendentious point of view, to foreign dimensions: Western and Eastern European. In these circumstances, there is a need to rehabilitate the production, distribution and consumption of the music industry of the Republic of Moldova by valorizing and capitalizing on local music production. The pandemic, forced digitalization and the external macroeconomic context, as well as the politico-military one, require updates and connections to contemporaneity. Therefore, musical activity within the borders regulated by a State must measure and appreciate its own potential, in order to apply appropriate legal rules. The governmental and parliamentary involvement, in this respect, consists in updating the aspects aimed at: the local music production (Law of the Republic of Moldova No. 139/2010); the minimum tariff s of the author remuneration (Government Decision of the Republic of Moldova, No. 641/2001) and 51% - the minimum valorization quota (Law of the Republic of Moldova No. 174/2018).

Assessment of prognostic markers of heart failure following acute myocardial infarction in patients treated with primary percutaneous coronary intervention
Authors: Marjanović Dajana , Miljković Jelena , Stanetić Bojan
Published: July 2022

Background / Aim: The concentration of N-terminal brain natrium peptides (NT-proBNP) is an important marker within the diagnostic and prognostic analysis of patients with chronic heart failure. In patients with ST-segment elevation myocardial infarction, natriuretic peptides are dominant predictors of death, heart failure and additional myocardial infarctions. The aim of this study was to correlate prognostic markers of heart failure following acute myocardial infarction. Methods: 193 patients with myocardial infarction were divided into two groups: 69 patients with NT-proBNP ≤ 1000 pg/mL and 124 patients with NT-proBNP > 1000 pg/mL. During the hospitalisation, laboratory data, clinical data and information on previous medications were collected. Echocardiography was used to identify left ventricular ejection fraction (LVEF). All statistical analysis were done in SPSS, version 23. Results: The group with elevated NT-proBNP (> 1000 pg/mL) was older (p < 0.001) and suffered more often of arterial hypertension (p = 0.04) and atrial fibrillation (p = 0.003). Heart rate was higher and LVEF was lower in patients with elevated NT-proBNP values (p < 0.001). Mean LVEF in the 193 patients was 46.86 %. In both linear and binary logistic regression analysis multiple predictors of elevated NT-proBNP have been identified. Conclusion: Increased ranges of NT-proBNP in patients following acute myocardial infarction are in correlation with decreased LVEF, elevated high-sensitive troponin I, lactate dehydrogenase, urea, creatinine, C-reactive peptides. This may guide clinicians to assess and treat early stages of heart failure.
Cardiotoxicity of high-dose methylprednisolone in patients with chronic lymphocytic leukemia: A case report
Authors: Apostolović-Stojanović Milica , Radojković Milica , Stojanović Aleksandar , Vukomanović Vladan
Published: July 2022

Introduction: Several classes of drugs can cause atrial fibrillation (AF) in patients without heart disease, as well as the occurrence of AF in pre-existing heart disease. Drug-induced AF is most often clinically manifested in the form of paroxysms. High doses of intravenous methylprednisolone (HDMP) in the treatment of chronic lymphocytic leukemia (CLL) have been associated with the occurrence of various adverse effects, including AF. The exact mechanism of HDMP-induced AF is unknown. Case presentation: We present the case of a patient with CLL in whom AF occurred after the administration of a high dose of intravenous methylprednisolone. Conclusion: Physicians should be aware of the special circumstances in the treatment of CLL, because drug-induced AF can be a side effect that limits further therapy.
Functioning, disability and exercise in the elderly
Authors: Kostadinović Milena , Dedović Sunčica , Milanović Filip , Aksović Nikola , Nikolić Dejan
Published: July 2022

The age of the population is increasing worldwide and is becoming an emerging problem in society. Maintaining physical as well as mental health, together with preventing and reducing disability, particularly in the older population, should be one of the most important aspects of successful aging. Thus, the goals of health programs should be the promotion of successful, active, and healthy aging. Elderly patients are usually associated with multiple medical conditions, which should be evaluated in a multidisciplinary fashion, bearing in mind the needs of this group of individuals. Even though it is assumed that aging is associated with a decline in functioning and, therefore, with reduced functional capacity in the elderly, it is important to identify the factors which play specific roles in healthy and active aging. Special consideration should be given to cognitive functioning. Furthermore, the elderly are at risk, due to habits characteristic of a sedentary lifestyle. Despite the positive effects of physical activity, particularly in the prevention and delay of chronic diseases and conditions, as well as in reducing the risk of premature death and in supporting positive mental health and healthy aging, the elderly population may face obstacles in terms of limited space for the safe execution of activities and the lack of proper knowledge on how to be active while taking into account one's physical limitations. When planning and implementing a physical activity, especially in the older population, the important factors that need to be considered include duration, frequency, intensity and mode. It should be stressed that exercise programs for the elderly should include aerobic, resistance, flexibility, and balance training.
An interesting case of Coronary-cameral fistula with angina pectoris
Authors: Lazović Dejan , Kočica Mladen , Đurošev Ivana , Kočica-Karadžić Milica , Cvetković Dragan
Published: July 2022

Introduction: Coronary-cameral fistula (CCF) is an anomalous connection between a coronary artery and a cardiac chamber. Most CCFs are discovered incidentally during angiographic evaluation of coronary vascular disorders. We report a case of CCF with angina pectoris. Case report: A 67-year-old woman presented with chest pain and dyspnea upon exertion. Coronary angiography showed atherosclerotic lesions in the two major coronary arteries, but also communication between three arteries and the cavity of the right ventricle (RV) through many small, diffuse fistulas. Angiography also showed a fistula between the proximal left anterior descending artery (LAD) (first septal branch) and the right ventricle, as well as between the proximal right coronary artery (RCA) (acute marginal branch) and the right ventricle. The patient qualified to undergo coronary artery bypass graft surgery (CABG) and surgical closing of the fistulas, which is why we performed, on a beating heart, double vessel revascularization by autovein graft between the ascending aorta and the RCA and between the ascending aorta and the LAD, as well as closing of the fistulas with hemoclips and polypropylene suture, with a teflon pledget. Conclusion: Hemodynamically insignificant fistulas, which are clinically silent and not associated with other abnormal findings, most commonly do not require further treatment. Large, hemodynamically significant fistulas should be closed by ligation. However, smaller fistulas tend to get larger with age and it is recommended that early elective closure is performed in patients experiencing symptoms or in asymptomatic patients with a continuous murmur or a systolic murmur with an early diastolic component.

Published: July 2022

Manoeuvring trials are often performed to assess the path keeping and path changing ability of a marine vehicle. Among them, depth-changing manoeuvres are of particular importance to underwater vehicles. This paper reports some 2D and 3D depth-changing manoeuvring trials that were performed in open-water using a large streamlined Autonomous Underwater Vehicle (AUV) of length 4.5 m. The paper outlines the method by which these tests were conducted and discusses the results and observations made thereof. In addition, numerical simulations of selected manoeuvres were used to validate a hydrodynamic model which is based on the ‘component build-up method’ and some typical results are also presented.
Open Water Tow Tank Testing of a Surface Piercing Propeller
Authors: Ellenrieder Karl , Lorio Justin , Altamirano Luis
Published: July 2022

Open water tests of a surface piercing propeller with a pitch to diameter ratio of 1.9 have been performed in a non pressurized towing tank. Flow visualizations of the ventilated cavities formed behind the propeller and Shaft line force/torque measurements were taken at tip immersion ratios of 0.50 and 0.33, yaw angles from 0° to 30° and inclination angles from 0° to 15° for advance ratios ranging from 0.8 to 1.9. Three wake parameters, the wake pitch, wake pitch angle and wake diameter, were identified and semi-automatically measured using composite images of the wake of the surface piercing propeller. The symmetry of the wake at non zero yaw angles, as well as the time evolution of the width of successive ventilated cavities in the wake were explored. It was found that the wake pitch angle changes proportionally to the advance ratio and does not change significantly as yaw angle changes; the ratio of wake diameter to SPP diameter increases as the advance ratio decreases; and the wake was most symmetric at a depth of immersion of 33%, a yaw angle of 15 degrees, zero shaft inclination angle, and an advance ratio of 1.2. The SPP was found to operate in a fully ventilated condition for scaled advanced ratios of 0.905 – 0.721. Asix-componentt load cell was integrated with the rotating propeller shaft line to provide measurements of propeller thrust, torque, side forces and moments. An examination of the efficiencies determined from these measurements and subsequent analyses reveal that, while the thrust measurements are near values expected from empirical relations, there appears to be an error in the torque measurements, likely due to an instrumentation problem. Nevertheless, the time histories of the load cell data are instructive in qualitatively illustrating the relation between carriage speed, propeller speed and the transient forces/moments acting on the propeller.
Detecção e análise dos fatores que influenciam o desenvolvimento humano e a trabalhabilidade dos trabalhadores
Authors: Ramos Pamela Adelino , Pereira Felipe Araujo
Published: July 2022

Com as complicações causadas pelo agravamento da pandemia provocada pelo coronavírus, iniciada no ano de 2020, onde diversos setores tiveram suas atividades interrompidas ou até paralisadas, vários colaboradores tiveram suas jornadas de trabalho diminuídas ou interrompidas, forçando-os a encontrar alternativas para se recolocar no mercado de trabalho. Nesse contexto, pode-se citar o termo trabalhabilidade, que tem como objetivo, segundo Maltby (2011), melhorar a qualidade do trabalho, incentivando uma melhor saúde mental e corporal, relacionando o ambiente de trabalho com o ambiente pessoal. Esse estudo teve como objetivo principal identificar e analisar fatores que influenciam o desenvolvimento humano e a trabalhabilidade dos trabalhadores. Após análise multivariada, utilizando o software SPSS, foi possível identificar dois fatores principais que correspondem ao estudo apresentado. O primeiro fator identifica características ligadas ao desenvolvimento pessoal dos trabalhadores, enquanto o segundo fator refere-se às questões sobre adequação e satisfação do trabalho como fatores determinantes no desenvolvimento profissional dos trabalhadores. Também foi observada a importância da satisfação como critério de melhoria profissional. Essa pesquisa também contribui para a melhor interpretação do relacionamento entre empregador e empregado, além de possibilitar diferentes perspectivas acerca da valorização de competências técnicas e interpessoais como melhoria no processo de trabalho, valorização profissional e captação de novas habilidades técnicas e emocionais para melhor desempenhar o trabalho e gerar valor através destas.
Diseño de un cuestionario para la Evaluación de las competencias de los Docentes de Educación Secundaria (SEVADES). Aplicación a los centros de Educación Secundaria de Santander
Authors: Diaz-Sarachaga Jose Manuel
Published: July 2022

Whether the identification of attitudes and behaviors good teachers should have is a daunting task, the assessment of these aspects, which is normally undertaken by students or agencies exterior to schools, is even more so. This study devised a new rating system to appraise the competences of secondary school teachers (SEVADES) through an in-depth literature review and questionnaires collected from 22 secondary education institutions in Santander (Spain). The application of the new tool aimed to self-evaluate 88 teachers from private and state schools, who obtained an average score of 8.341 points (Very good). For state secondary schools, scarce differences between the assessment of managers and teachers were reported. Regarding private institutions, managers slightly outperformed lecturers’ scores. Whilst Leadership was the most appreciated attitude, Vocation was assigned the lowest rates.

Si la determinación de las actitudes del buen docente es una tarea complicada, aún lo es más su evaluación, habitualmente realizada por el propio alumnado u otros colectivos ajenos a los centros educativos. Esta investigación diseñó un Sistema de Evaluación de las Competencias de los Docentes de Educación Secundaria (SEVADES) mediante la revisión de la literatura especializada y la participación de los directivos de 22 centros educativos de Santander. La aplicación de la nueva herramienta permitió la autoevaluación de 88 docentes de centros públicos y concertados, quienes obtuvieron una puntuación media de 8.341 puntos (Muy Bueno). Se apreciaron pequeñas diferencias entre las valoraciones de los directivos y las de los docentes de los centros públicos. En los centros concertados, la puntuación de los directivos fue ligeramente superior a la de los docentes. El Liderazgo fue la actitud más valorada por los directivos y docentes, mientras la Vocación reflejó la nota más baja.

En el artículo se describe el proceso de validación de contenido que se ha llevado a cabo con cinco expertos en la materia, más un alumno de doctorado afín al tema, y el análisis de la fiabilidad del instrumento por 48 estudiantes de las cuatro titulaciones de Educación de la Universidad del País Vasco (UPV/EHU) en los tres campus universitarios. Los resultados apuntan a que fueron positivos con respecto al índice de validez de contenido en 0.81 y una consistencia interna superior a 0.6, mediante el coeficiente Alfa de Cronbach. Se concluye apuntando a que estos cuestionarios pueden ser transferidos a otros contextos que compartan un objetivo igual o similar y abren la posibilidad de monitorizar las competencias transversales en la asignatura del TFG para los Grados de Educación.
From Nottinghamshire to Notting Hill: Contemporary Lessons from Pearl Jephcott’s Ethnographies of ‘Troubled Areas’
Authors: Goodwin John , O'Connor Henrietta , Parsons Laurie
Published: July 2022

The work of largely forgotten sociological researcher Pearl Jephcott is increasingly being recognised for its methodological complexity and innovation, and community-orientated approach. Here we revisit two of Jephcott’s lesser-known works. Yet again both working around issues that attracted great sociological interest in the 1950s and 1960s but were in many ways pioneered by Jephcott. The authors begin by exploring her study of youth delinquency in a Nottinghamshire village, Hucknall, and move on to revisit her work on North Kensington in the late 1950s, widely viewed at the time as what she called ‘a troubled area’. This closes with a review of the ‘lessons’ contemporary researchers can learn from Jephcott’s two studies.
Modelizar y construir representaciones externas sobre la síntesis de proteínas: un estudio de diseño en la escuela secundaria
Authors: Occelli Maricel , Pomar Susana , Gómez Galindo Alma Adrianna
Published: July 2022

Diferentes estudios registran que el estudiantado suele emitir explicaciones lineales entre genotipo y fenotipo en las cuales se pasa por alto el rol de las proteínas. En este trabajo se caracterizan los aprendizajes asociados a la síntesis de proteínas que se promueven al modelizar y construir representaciones externas digitales animadas. Se desarrolló una investigación basada en diseño durante dos años consecutivos (2017-2018) en un 5º año (16 o 17 años) de una escuela secundaria de Córdoba (Argentina). En el primer año se estudió la propuesta de enseñanza que venía desarrollando la docente y en el segundo año se codiseñó una secuencia que planteó la modelización de la síntesis de proteínas y la construcción de representaciones externas digitales animadas. Los resultados indican que la creación de representaciones dinámicas fomentó el razonamiento basado en modelos y el estudiantado logró conectar a los genes con la codificación de proteínas, empezando a superar nociones superficiales asociadas a la relación genotipo-fenotipo.

Diseño y evaluación de un programa de intervención para trabajar conceptos temporales en Educación Infantil
Authors: Vivas Moreno Verónica , Miralles Martínez Pedro , Gómez Carrasco Cosme Jesús
Published: July 2022

Diversos investigadores afirman que se puede enseñar cualquier contenido a través de cuentos no específicos para su enseñanza, incluso en el caso de contenidos de ciencias. El objetivo de esta investigación es diseñar, aplicar y evaluar una propuesta de enseñanza de conceptos temporales en Educación Infantil a través de un cuento no específico para la enseñanza de las ciencias sociales. La información se recoge en tablas de evaluación posteriormente analizadas con el programa SPSS. La propuesta incluye un torbellino de ideas para la detección de ideas previas del alumnado y dos cuestionarios analizados con el programa ATLAS.ti. Los resultados muestran un alto porcentaje de consecución de los objetivos, encontrando diferencias algo significativas entre un aula y otra. Ello nos lleva a concluir que la enseñanza de conceptos temporales sí se puede llevar a cabo en Educación Infantil a través de cuentos no específicos para su enseñanza.
Postpornografía. La revolución de la periferia y sus aristas
Authors: Vellarino Albuera Susana
Published: July 2022

Hace ahora treinta años que se puso en circulación el término postpornografía y casi veinte del auge de la misma. Pasado este tiempo y en un momento como el actual en el que se están resquebrajando algunos de los principios sobre los que se sustentaban nuestras certezas parece oportuno revisar algunas cuestiones fundamentales dentro de las tecnologías de producción postpornográficas y de los planteamientos que subyacen a las mismas. Este artículo analiza en primer lugar la confusión terminológica que rodea a la postpornografía, sin perder de vista la pretensión de indefinición que ha flotado en todo momento sobre sus planteamientos. Un segundo punto reflexiona sobre el que se postulaba como principal objetivo de esta metapornografía, el de dinamitar el sistema de producción de verdad del sexo de la pornografía. Como punto final este análisis se detiene en las derivas de los feminismos en las últimas décadas y cómo afectan a la postpornografía, teniendo en cuenta las raíces feministas (transfeministas) de la misma.  La finalidad última de este trabajo es abrir un debate que ayude a reubicar y reflexionar sobre el estado actual de la producción postporno.
Nuevas direcciones para la estética ecológica en la literatura española neorrural (2013-2020)
Authors: Berbel García Rosa María
Published: July 2022

El retorno al campo se ha convertido en la última década en un motivo literario relevante y habitual, como atestigua la consolidación del fenómeno neorrural. Pese al evidente protagonismo de que ha gozado la tensión entre el campo y la ciudad en la tradición española, los textos recientes revelan formas nuevas de relación con el territorio, cercanas en sus postulados a algunas articulaciones ecologistas actuales y a las ecoescrituras. De este modo, el presente artículo propone una relectura del corpus neorrural a la luz de las estéticas ecológicas, tratando, por un lado, de comprender las obras más allá de las representaciones localistas, desde el ámbito de lo posnacional o lo glocal; y por el otro, de formular un vínculo con el medioambiente y la naturaleza que potencie también una consideración constructiva de la ciudad, como espacio de alianzas políticas y encuentros emancipatorios para la comunidad. Para ello, partiremos de algunas de las obras más representativas de las nuevas ruralidades, desde la célebre Intemperie de Jesús Carrasco a Tierra de mujeres de María Sánchez, pasando por ficciones como las de Irene Solà, Lara Moreno o Alberto Olmos.
El soldado sublevado en el boom de memoria: perspectivas y desafíos en su representación
Authors: Casas-Olcoz Ana María
Published: July 2022

El presente artículo estudia la novela española con temática guerracivilista publicada desde el año 2000 con una doble finalidad: evidenciar el tratamiento literario y escasez cuantitativa de novelas en que el soldado miembro del bando sublevado tiene una importancia constitutiva —tanto en protagonismo como en profundidad del personaje— y señalar los retos ético-políticos a que se enfrenta el tratamiento de su perspectiva: el  riesgo de empatía e identificación con el victimario, la superación de esquemas reduccionistas y la posibilidad de refrendar ideas antidemocráticas. Con esto se pretende contribuir al estudio de la novela reciente española y específicamente de una de sus vetas más productivas, el tratamiento literario de la guerra civil española.

The major microtubule-organizing center (MTOC) in animal cells, the centrosome, comprises a pair of centrioles surrounded by pericentriolar material (PCM), which nucleates and anchors microtubules. Centrosome assembly depends on PCM binding to centrioles, PCM self-association and dynein-mediated PCM transport, but the self-assembly properties of PCM components in interphase cells are poorly understood. Here, we used experiments and modeling to study centriole-independent features of interphase PCM assembly. We showed that when centrioles are lost due to PLK4 depletion or inhibition, dynein-based transport and self-clustering of PCM proteins are sufficient to form a single compact MTOC, which generates a dense radial microtubule array. Interphase self-assembly of PCM components depends on γ-tubulin, pericentrin, CDK5RAP2 and ninein, but not NEDD1, CEP152, or CEP192. Formation of a compact acentriolar MTOC is inhibited by AKAP450-dependent PCM recruitment to the Golgi or by randomly organized CAMSAP2-stabilized microtubules, which keep PCM mobile and prevent its coalescence. Linking of CAMSAP2 to a minus-end-directed motor leads to the formation of an MTOC, but MTOC compaction requires cooperation with pericentrin-containing self-clustering PCM. Our data reveal that interphase PCM contains a set of components that can self-assemble into a compact structure and organize microtubules, but PCM self-organization is sensitive to motor- and microtubule-based rearrangement.

High-parameter single-cell phenotyping has enabled in-depth classification and interrogation of immune cells, but to date has not allowed for glycan characterization. Here, we develop CyTOF-Lec as an approach to simultaneously characterize many protein and glycan features of human immune cells at the single-cell level. We implemented CyTOF-Lec to compare glycan features between different immune subsets from blood and multiple tissue compartments, and to characterize HIV-infected cell cultures. Using bioinformatics approaches to distinguish preferential infection of cellular subsets from viral-induced remodeling, we demonstrate that HIV upregulates the levels of cell-surface fucose and sialic acid in a cell-intrinsic manner, and that memory CD4+ T cells co-expressing high levels of fucose and sialic acid are highly susceptible to HIV infection. Sialic acid levels were found to distinguish memory CD4+ T cell subsets expressing different amounts of viral entry receptors, pro-survival factors, homing receptors, and activation markers, and to play a direct role in memory CD4+ T cells’ susceptibility to HIV infection. The ability of sialic acid to distinguish memory CD4+ T cells with different susceptibilities to HIV infection was experimentally validated through sorting experiments. Together, these results suggest that HIV remodels not only cellular proteins but also glycans, and that glycan expression can differentiate memory CD4+ T cells with vastly different susceptibility to HIV infection.

Forest soil carbon (C) sequestration has an important effect on global C dynamics and is regulated by various environmental factors. Mixed and pure plantations are common afforestation choices in north China, but how forest type and environmental factors interact to affect soil C stock remains unclear. We hypothesize that forest type changes soil physicochemical properties and surface biological factors, and further contributes to soil active C components, which together affect soil C sequestration capacity and C dynamic processes. Three 46-year-old 25 m × 25 m pure Pinus tabulaeformis forests (PF) and three 47-year-old 25 m × 25 m mixed coniferous-broadleaf (Pinus tabulaeformis-Quercus liaotungensis) forests (MF) were selected as the two treatments and sampled in August 2016. In 2017, soil temperature (ST) at 10 cm were measured every 30 min for the entire vegetation season. Across 0–50 cm (five soil layers, 10 cm per layer), we also measured C components and environmental factors which may affect soil C sequestration, including soil organic carbon (SOC), soil total nitrogen (STN), dissolved organic carbon (DOC), microbial biomass carbon (MBC), soil moisture (SM) and soil pH. We then incubated samples for 56 days at 25 °C to monitor the C loss through CO2 release, characterized as cumulative mineralization carbon (CMC) and mineralized carbon (MC). Our results indicate that ST, pH, SM and litter thickness were affected by forest type. Average SOC stock in MF was 20% higher than in PF (MF: 11.29 kg m−2; PF: 13.52 kg m−2). Higher CMC under PF caused more soil C lost, and CMC increased 14.5% in PF (4.67 g kg−1 soil) compared to MF (4.04 g kg−1 soil) plots over the two-month incubation period. SOC stock was significantly positively correlated with SM (p < 0.001, R2 = 0.43), DOC (p < 0.001, R2 = 0.47) and CMC (p < 0.001, R2 = 0.33), and significantly negatively correlated with pH (p < 0.001, R2 = −0.37) and MC (p < 0.001, R2 = −0.32). SOC stock and litter thickness may have contributed to more DOC leaching in MF, which may also provide more C source for microbial decomposition. Conversely, lower SM and pH in MF may inhibit microbial activity, which ultimately makes higher MC and lower CMC under MF and promotes C accumulation. Soil mineralized C drives more C stock in coniferous-broadleaf mixed plantations compared to pure plantations, and CMC and MC should be considered when soil C balance is assessed.

Phaeodactylum tricornutum is a marine diatom with a growing genetic toolbox available and is being used in many synthetic biology applications. While most of the genome has been assembled, the currently available genome assembly is not a completed telomere-to-telomere assembly. Here, we used Oxford Nanopore long reads to build a telomere-to-telomere genome for Phaeodactylum tricornutum. We developed a graph-based approach to extract all unique telomeres, and used this information to manually correct assembly errors. In total, we found 25 nuclear chromosomes that comprise all previously assembled fragments, in addition to the chloroplast and mitochondrial genomes. We found that chromosome 19 has filtered long-read coverage and a quality estimate that suggests significantly less haplotype sequence variation than the other chromosomes. This work improves upon the previous genome assembly and provides new opportunities for genetic engineering of this species, including creating designer synthetic chromosomes.
Respiratory Syncytial Virus Infection in Infants: A Comparative Study Using Discriminant, Probit and Logistic Regression Analysis

Published: July 2022

In babies, respiratory syncytial virus (RSV) is the most common cause of lung inflammation (pneumonia) or bronchiolitis (inflammation of the lungs' airways). This virus comes with several symptoms such as congested or runny nose, dry cough, low-grade fever, sore throat, sneezing, headache, difficulty in breathing etc. The virus can cause death in babies if not properly managed and therefore calls for immediate investigations to reveal the significant causes. Several research works have been conducted but the idea of investigating more potential predictor variables and the application of both regression and classification models have been grossly understudied. Therefore, unpublished secondary data collected from three different hospitals in Port Harcourt, Rivers State, Nigeria on fifteen predictor variables which are potential causes of RSV are modeled using two categorical regression approaches – logistic and probit regression models and one classification model – discriminant function analysis. The models were compared using misclassification errors, Receiver Operating Characteristic (ROC) plot, concordance, sensitivity, specificity and pseudo R-square values. The linear discriminant function model outperformed both the logit and probit models. The results showed that paternal history of asthma, maternal history of asthma, mother’s occupation, mother’s smoking habit and mother’s education level were the most important variables to linearly classify seropositive and seronegative RSV patients.

Aims: To study and estimate the forest cover loss and gain across the 13 districts of Uttarakhand.

Place and Duration of Study: Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, between September 2021 and December 2021.

Methodology: We extracted forest cover time-series data from the year 2001 to the year 2020 from Hensen Global Forest Change Dataset. This data was then mapped to the shapefile created in ARC-GIS containing all 13 districts as a Feature Collection, which was then used to individually classify each region and to estimate the size of the loss of tree cover precisely over the district boundary.

Results: Our study shows forest loss of about (21,05,71,646 square meters) and forest gain of (6,00,79,072 square meters) cumulatively in all the districts of Uttarakhand from the year 2001 to 2020 at a spatial resolution of 30 meters where trees were identified as canopies greater than 5 meters in height.

Conclusion: Among the districts of Uttarakhand Udham Singh Nagar, Nainital, and Champawat alone contribute to the total tree cover loss area of 15061.7513801 ha. which is about 71.5 % of Uttarakhand’s total tree cover loss. These regions require monitoring and controlling deforestation and more detailed studies like this are required to analyze and prevent the causes of such great-scale deforestation. Analyzing districts apart from those mentioned above, it is observed that the amount of tree cover loss is greater than the reforestation.

A field experiment was conducted to assess the effect of drip fertigation and foliar nutrition of liquid multi nutrient on growth, yield and quality parameters of hybrid cotton. Liquid fertilizer was formulated using micronutrient (Zn, Fe, Mn, B, Mo, Cu), Mg and S to meet the nutrient requirement of hybrid cotton. Field experiment was laid out in Randomized Block Design with three replications and seven treatments. Drip fertigation was applied with 100% recommended dose of fertilizer (RDF) through water soluble fertilizer and Liquid Multinutrient (LMN). Treatment that received 100% RDF + LMN fertigation and foliar nutrition of LMN recorded the highest growth parameters (plant height, Leaf Area Index and dry matter production), yield parameters like number of sympodial branches/plant, number of bolls/plant, boll weight, seed cotton yield and quality parameters like staple length and ginning out turn per cent and in addition to that foliar nutrition of LMN containing Mg alleviated the Mg deficiency to the tune of 52% which in turn increases the above parameters. Fertigation and foliar nutrition of LMN enhanced the nutrient uptake of hybrid cotton that would economize the cost of fertilizer input.
