The Trend and the Pattern of Seasonal Rainfall in the Period (1993-2018) in Embu East Sub County, Kenya
Authors: Ireri Linus Mugendi 
Published: June 2020

Kenya, like many countries in the world, is vulnerable to climate variability and change. The livelihood of the people in Embu East Sub-county is highly dependent on rain-fed agriculture so climatic threats affect food and animal production. Climate variability has negatively affected mixed crop-livestock production. The objective of this study was: to establish the trend in seasonal rainfall in the period (1993-2018). The study used a descriptive survey research design guided by the Sustainable Livelihood Approach (SLA) theory. A sample of 364 subjects was composed of 362 heads of farming families and 2 Agricultural Field Officers. Data was obtained through the study of rainfall records in Embu Meteorological Stations, administration of household questionnaires, and interview schedule. The Methods of data analysis and presentation included time-series line graphs to show the trend, frequency tables, and percentages. The coefficient of variation was used to check the homogeneity of March-April-MAY and October-November-December seasons. A paired sample was used to test the hypothesis. The findings established that the rainfall trend was irregular between the years 1993-2018. The onset and the cessation of the MAM and OND varied significantly even though the MAM rainfall was on the upward trend and that of the OND was on the downward trend. The study recommends the following strategies the need to establish more rainfall stations in the study area. Policymakers should build the capacity of the farmers on how to exploit MAM fully and OND seasons and design a more efficient and interactive approach among the climate scientist-decision makers and the farmers to ensure effective communication on rainfall trends and pattern.

Disentangling stimulus and response compatibility as potential sources of backward crosstalk
Authors: Rieger Tobias , Miller Jeff 
Published: June 2020

AbstractIn two experiments (N= 60 each), we investigated the locus of backward crosstalk effects in dual tasking. Specifically, we embedded the typical flanker task within a dual-task paradigm by assigning stimulus-response (S-R) rules to the flankers. In Experiment 1, participants were instructed to first respond to the center letter and only respond to the flanker if the center was a no-go stimulus (i.e., prioritized processing paradigm). Mapping condition was varied between-subjects to be either matched (i.e., same S-R rule for flankers as for center letters), reversed (i.e., opposite S-R rule for flankers), or neutral (i.e., different letters for flankers with separate S-R rules). The results indicated that the backward crosstalk effect was mainly driven by a stimulus-based compatibility, as indicated by a significant S2−R1 compatibility effect in the matched and reversed conditions, with little change in this effect between the matched and reversed conditions. Experiment 2 replicated and extended these findings to a psychological refractory period paradigm. The present findings suggest that in the matched and reversed conditions, there was only one S-R rule active at a time.

Published: June 2020

AbstractSeeing a talker’s face can aid audiovisual (AV) integration when speech is presented in noise. However, few studies have simultaneously manipulated auditory and visual degradation. We aimed to establish how degrading the auditory and visual signal affected AV integration. Where people look on the face in this context is also of interest; Buchan, Paré and Munhall (Brain Research, 1242, 162–171, 2008) found fixations on the mouth increased in the presence of auditory noise whilst Wilson, Alsius, Paré and Munhall (Journal of Speech, Language, and Hearing Research, 59(4), 601–615, 2016) found mouth fixations decreased with decreasing visual resolution. In Condition 1, participants listened to clear speech, and in Condition 2, participants listened to vocoded speech designed to simulate the information provided by a cochlear implant. Speech was presented in three levels of auditory noise and three levels of visual blurring. Adding noise to the auditory signal increased McGurk responses, while blurring the visual signal decreased McGurk responses. Participants fixated the mouth more on trials when the McGurk effect was perceived. Adding auditory noise led to people fixating the mouth more, while visual degradation led to people fixating the mouth less. Combined, the results suggest that modality preference and where people look during AV integration of incongruent syllables varies according to the quality of information available.

Authors: Непершин Ростислав Иванович 
Published: June 2020

Приведено численное моделирование пластического сдавливания цилиндра плоскими штампами по нормали к его оси на основе теории плоской деформации жесткопластического тела. Рассматриваются начальная пластическая деформация с выдавливанием материала на свободную поверхность цилиндра, переходящая в пластическое деформирование высокой заготовки и пластического слоя с конечным отношением длины контакта к толщине. Используются линии скольжения и скорости пластического течения по Прандтлю при изменении формы деформируемого сечения цилиндра с учетом контактного трения при сдавливании пластического слоя. Моделирование представляет практический интерес для оценки предельной нагрузки при контактной деформации цилиндра плоскими штампами и деформировании заготовки при ковке плоскими бойками.
Computer simulation of the rigid-plastic cylinder compression by the flat dies is presented using plane strain ideal plastic theory. Initial contact plastic deformation with material lip forming on the free cylinder surface, followed by the high workpiece and the plastic layer with finite contact length to thickness relation plastic deformation are considered. Prandtl’s slip lines and velocity fields are used for the cylinder section form predictions and plastic layer compression with contact friction consideration. Computer simulation can be used for the limit load estimation with cylinder contact plastic flow, compressed by the flat rigid dies, and cylinder workpiece forging by the flat dies.

In the paper the problem of calculating of the optimal loading pressure during material deformation under creep is considered. The solution of the boundary-value problem is constructed within the frameworks of the model of large elastic-creep deformations. The obtained numerical solution is used to find the optimal loading process necessary to achieve a given size of a single microdefect. The search for the optimal solution is carried out on the set of 5-order polynomials by a brute-force search. The resulting solution is analyzed graphically and compared with previously obtained results.
Éducation à l’environnement ou acculturation ?
Authors: Bidou Jean-Étienne 
Published: June 2020

Cet article présente l’analyse de représentations des relations entre environnement et développement en se basant sur les discours de trois grands groupes de personnes : des Peuls ruraux du Fouta Djallon en Guinée, des lycéens et étudiants de deux villes burkinabées (Bobo Dioulasso et Ouagadougou) et des lycéens de Niort en Poitou-Charentes (France). Ces corpus, traités par un logiciel d’analyse textuelle, montrent que les représentations des jeunes citadins burkinabés et celles des jeunes Français sont très voisines et s’opposent à celles des ruraux Guinéens. Si ces représentations traduisent des différences culturelles, il faut conclure qu’elles n’opposent plus, sur le thème traité, les populations du Nord et du Sud, mais qu’au contraire les ruraux Africains forment un ilot culturel face à une culture urbaine mondialisée à laquelle participent les grands thèmes environnementaux actuels. L’auteur s’interroge dans quelles conditions l’éducation à l’environnement peut œuvrer de façon à être mieux en prise avec les cultures locales.

Abstract
During inflammation, endothelial cells are bombarded with cytokines and other stimuli from surrounding cells. Leukocyte extravasation and vascular leakage are both prominent but believed to be uncoupled as they occur in separate spatiotemporal patterns. In this study, we investigated a “double-hit” approach on primary human endothelial cells primed with LPS followed by histamine. Using neutrophil transendothelial migration (TEM) under physiological flow assays, we found that an LPS-primed endothelium synergistically enhanced neutrophil TEM when additionally treated with histamine, whereas the effects on neutrophil TEM of the individual stimuli were moderate to undetectable. Interestingly, the double-hit–induced TEM increase was not due to decreased endothelial barrier, increased adhesion molecule expression, or Weibel–Palade body release. Instead, we found that it was directly correlated with junctional remodeling. Compounds that increased junctional “linearity” (i.e., stability) counteracted the double-hit effect on neutrophil TEM. We conclude that a compound, in this case histamine (which has a short primary effect on vascular permeability), can have severe secondary effects on neutrophil TEM in combination with an inflammatory stimulus. This effect is due to synergic modifications of the endothelial cytoskeleton and junctional remodeling. Therefore, we hypothesize that junctional linearity is a better and more predictive readout than endothelial resistance for compounds aiming to attenuate inflammation.
Neurolymphomatosis – Rare presentation in non-Hodgkin's lymphoma: The role of 18F-fluorodeoxyglucose positron-emission tomography and computerized tomography imaging

Published: June 2020

AbstractNeurolymphomatosis (NLS) is infiltration of lymphoma cells into the peripheral or cranial nervous system and is a rare manifestation of non-Hodgkin lymphoma (NHL). Nerve biopsy is considered as the gold standard for diagnosis but not a preferred choice, and magnetic resonance imaging has lower reported sensitivity. 18F-Fluorodeoxyglucose (18FDG) positron-emission tomography and computerized tomography (PET/CT) has a higher sensitivity for diagnosing and assessing the neurological and nonneurological metabolic tumor volume and response evaluation to therapy. We present the case of a lady, known to have NHL in remission. She presented with a short history of severe pain and weakness of the right lower limb. Baseline and interim 18FDG PET/CT played a crucial role in diagnosing and assessing the extent of NLS and nonneurological disease burden and also in evaluation of response to treatment.

Published: June 2020

AbstractThe practical diagnostic performance of Prospective Investigative Study of Acute Pulmonary Embolism Diagnosis (PISAPED) criteria for the detection of acute pulmonary thromboembolism (APTE) in hospitalized patients is not yet well determined. This is the report of the initial results of our recently implemented protocol to employ PISAPED. One hundred and forty-seven pulmonary perfusion scans with 1–3 mCi 99mTc-MAA of patients of a single pulmonologist were included. Patients with suspicious perfusion defects underwent single-photon emission computed tomography. Interpretations were done by consensus of two nuclear medicine specialists. Comparisons were done with chest X-ray or chest computed tomography when available. The interpreters had access to the clinical records. The scans were reported based on the PISAPED criteria as negative or positive for APTE or indeterminate. Patients were followed up for 6.2 ± 5.3 months when the final diagnosis confirming or excluding APTE was achieved. Patients aged 55.9 (17.2) years; 78 (53.1%) of them were female and 64 (43.8%) had high Wells' score. The scans were positive, negative, and indeterminate in 17 (11.6%), 126 (85.7%), and 4 (2.7%) patients, respectively. In 6 out of 147 patients, follow-up was not completed and the final diagnosis was not achieved. APTE was finally diagnosed in 21 (14.3%) patients; 12 (57.1%) of them had positive scans. APTE was excluded in 116 (78.9%) patients; 112 (96.5%) of them had negative scans. The accuracy of the test for the diagnosis of APTE was 87.9%. Lung metastasis was the most frequent reason among false-negative cases. The lung perfusion scan using PISAPED criteria could be used with good accuracy in inpatient settings.

Published: June 2020

The study assessed the factors affecting entrepreneurship development among Food Marketers in Ilorin Metropolis, Kwara State, Nigeria. One hundred and ten respondents were randomly selected in four markets in Ilorin. The data was analyzed using frequency count, percentage, mean and Pearson Product Moment Correlation. The result reveals that mean age of the respondents was 30.5 years and about 58.2% were female. Record keeping skills (mean score =2.42) was the highest ranked entrepreneurial information needs of the respondents while lack of start-up capital (mean score =2.40) was the most severe factor affecting entrepreneurial activities of food marketers. There is a weak positive significant relationship between the entrepreneurial information needs and factors affecting entrepreneurial development of the respondents (r=0.407, p=0.0001). The study recommends that there should be provision of training on entrepreneurial skills based on the identified areas of needs and there should be provision of credit facilities to the food marketers as these will enhance their productivity.

Published: June 2020

The phosphorites of the Ameki Formation occur as nodules, pellets as well as primary phosphatic shales and siltstones. Geochemical analysis of the phosphate samples was carried out to determine its chemical composition as well as its depositional environment. The methodology applied include XRF, INAA, XRD and thin section petrography using Polarizing Microscope. The XRF result identified CaO- P2O5- F as the major mineral group, SiO2, Al2O3, Fe2O3, MgO and TiO2, which show minor occurrences and Cr, U, Pb, V, Cu, Zn, Se and Cd that occur in trace amounts. The nodules and pellets are of medium to high grade (25- 34wt% P2O5) whereas the primary phosphatic shales and siltstones are of low to medium grade (4.5– 22wt% P2O5). The phosphorites comprise mostly of francolites. The mean index of refraction estimated by Becke-line method using Standard Polarizing Microscope gave 1.634 and1.636.XRD analysis yielded an average values of 9.243 (± 0.002) A° and 6.715 (± 0.002) A° for a and c crystallographic axes respectively with an axial ratio (c/a) of 0.726for unit cell parameter, suggestive of low degree of carbonate substitution. An increase in P2O5 content is found to be accompanied by increase in CaO, CO2 and F contents, but by a decrease in H2O, organic carbon, SiO2 and Fe contents indicative of amorphous solid phase of calcium phosphate. The phosphorite is interpreted to form under high biologic productive, shelf setting. High nutrient availability in the ancient sea is linked to upwelling along the West African Coastline during the Eocene.
