Published: September 2021

Background: Climate change and consequent increases in rainfall variability may have negative consequences for the food production of subsistence farmers in West Africa with adverse impacts on nutrition and health. We explored the pathway from rainfall through diet up to child undernutrition for rural Burkina Faso.Methods: The study used data of a dynamic cohort with 1,439 children aged 7–60 months from the Nouna Health and Demographic Surveillance Site (HDSS) for 2017 to 2019. We assessed data on diets, height, weight, household characteristics, and daily precipitation (from 1981 to 2019). Principal component analysis was used to identify distinct child dietary patterns (Dietary Pattern Scores, DPS). These were related to 15 rainfall indicators by area to obtain a precipitation variability score (PVS) through reduced rank regression (RRR). Associations between the PVS and anthropometric measures, height-for-age (HAZ), and weight-for-height (WHZ), were examined using multi-level regression analysis.Results: Stunting (HAZ &lt; −2) and wasting (WHZ &lt; −2) were seen in 24 and 6% of the children. Three main dietary patterns were identified (market-based, vegetable-based, and legume-based diets) and showed mixed evidence for associations with child undernutrition. The RRR-derived PVS explained 14% of the total variance in these DPS. The PVS was characterized by more consecutive dry days during the rainy season, higher cumulative rainfall in July and more extremely wet days. A 1-point increase in the PVS was associated with a reduction of 0.029 (95% CI: −0.06, 0.00, p &lt; 0.05) in HAZ in the unadjusted, and an increase by 0.032 (95% CI: 0.01, 0.06, p &lt; 0.05) in WHZ in the fully adjusted model.Conclusion: Rainfall variability was associated with dietary patterns in young children of a rural population of Burkina Faso. Increased rainfall variability was associated with an increase in chronic undernutrition, but not in acute undernutrition among young children.

Objectives: To compare the performance and outcomes of monopolar electrosurgical conization (MESC) or the loop electrosurgical excision procedure (LEEP) in the treatment of high-grade squamous intraepithelial lesion (HSIL).Methods: This retrospective study included 554 patients diagnosed with HSIL through biopsy. The study used either LEEP or MESC for cervical conization. Additionally, the medical records of these patients, including the basic information, status of the excision margin, cone depth, cone width, fragmentation, complication, and the results of a 6-month follow-up after conization, were reviewed.Results: Compared to MESC, LEEP had a significantly higher rate of positive endocervical margin (3.77 vs. 8.65%; p = 0.018), burn injury of the margin (4.90 vs. 10.38%; p = 0.016) and a lower rate of adequate cone depth (83.40 vs. 89.62%; p = 0.034). In addition, LEEP was significantly more likely to cause fragmentation (p = 0.000). There was, however, no significant difference in the rate of abnormal cervical cytology and positive high-risk HPV (hrHPV) between these two groups, 6 months after cervical conization.Conclusion: Both LEEP and MESC appeared to be equally effective in the clinical treatment of HSIL. Nonetheless, MESC resulted in a better pathological outcome with regard to the status of the margin, tissue fragmentation, and cone depth.

Published: September 2021

Liver is chemically complex matrixes contain sufficient nutrients that support microbial growth. Microbial contamination of vending chicken livers could occur due to different possible reasons such as storing foods in cheap utensils, holding foods at a temperature that would permit bacterial growth, utilization of water of questionable hygienic quality, using packing materials that were not of food-grade quality, vending site that has no facilities for waste disposal and utilization of unclean utensils. In addition, street chicken livers vendors are unaware of the basic importance of personal cleanliness, thus their products are usually vulnerable to gross contamination by flies, insects, rodents, dust and other dirt. Vending chicken livers are often poor and uneducated and lack appreciation for safe food handling. Aim of the study is to determine microbiological quality of chicken livers in Jalalabad city. A total of 24 samples of vender chicken livers from 4 different shops had purchased from Jalalabad city Afghanistan. This step occurred earlier than the chilling period then Transfer Directly to the Microbiological laboratory of Veterinary Science faculty of Nangarhar University for Microbial culture and microscopic examination. According to our study we have seen 6 (25%) samples positive for Salmonella and 24(100%) samples positive for Shigella. Studies made in Nangarhar pointed out that the important aspect of vending chicken livers is their safety and understanding the possible ways of contamination. The sanitary condition need to be improved. The government must develop microbiological standards of fast food and urgently put them in practice.
Thermal effect of carbohydrate dissolution in aqueous-organic media
Authors: Danilchuk Yulia V 
Published: September 2021

This work is devoted to the theoretical substantiation of connection of temperature dependence of the solubility of carbohydrates with thermal effect of their dissolution in the water-containing organic solvents that is of great importance for optimization of the technology of their extraction from plant raw materials and further purification and separation by recrystallization. The dependence of the solubility of fructose, glucose, sucrose, and maltose in aqueous isopropanol and acetone at temperatures of 298 К (25 оС) and 275 К (2 оС) from water content in a solvent was studied. The constancy of the mechanism of solubility of carbohydrates in these environments in the given temperature interval is experimentally proved. For the first time based on the equation of Vant-Goff the logical connection of temperature dependence of solubility and thermal effect of solubility of carbohydrates is strictly grounded. The values of the thermal effect that are determined by the experimental data allow calculating the solubility of the studied carbohydrates in the aqueous–organic solvent of different concentration in the temperature range from 2оС to 25 оС. It has been established that the main contribution to the thermal effect of dissolving carbohydrates is the hydration process. Solvation by molecules of organic solvent practically does not change the value of the specified thermal effect. The significance of determined temperature dependences of the solubility of fructose, glucose and maltose is shown to optimize the technological conditions for the separation of glucose-fructose and glucose-maltose syrups by selective crystallization.

Published: September 2021

O conforto térmico do ambiente construído é um conteúdo fortemente relacionado com os elevados índices de consumo de energia elétrica decorrentes do uso de sistemas de condicionamento artificial de ar para se alcançar condições térmicas ambientais desejáveis. Esse consumo é consequéncia, principalmente, da inadequação dos elementos arquitetônicos aos aspectos climáticos locais e às demandas de conforto humano. O estudo das propriedades térmicas de materiais construtivos é, portanto, um relevante campo de estudo quando se deseja aliar conforto térmico e economia de energia. Com base em uma investigação interdisciplinar envolvendo Design, Arquitetura e Engenharia, este artigo mostra a importância da análise de conceitos como o da difusividade térmica de materiais construtivos no planejamento do conforto térmico de edificações.

The process of development of modern video surveillance systems in maritime transport is investigated, as well as some applications and features of image transmission and methods that increase its efficiency are touched upon. Maritime surveillance systems can be used to improve the security of ports, airports, commercial and military vessels, as well as to control sea traffic in ports and channels, protect coastal and oil platforms. Cameras are one of the main sensors of these systems. They are cheap and complement other types of sensors. This paper presents the results of research on the use of the fast Fourier transform algorithm with decimation in time at a dimension of-22´22 when processing marine scenes obtained from various surveillance cameras for the Crimean bridge. The proposed algorithm is obtained by applying a two-stage approach to decomposition and implementing an effective method for grouping the rotary multipliers of the Fourier transform in a complex form. The arithmetic complexity of the proposed algorithm is analyzed and the number of real multiplications and additions for various sizes of transformation and images of sea vessels is calculated. In addition, the estimation of the transmission speed and complexity of processing marine images for various formats and resolutions was performed.

Expressions for determining the periods of the natural transverse and longitudinal vibrations of the vessel, both exact and approximate, are given, but at the same time sufficient for their practical use on the vessel. The formulas for calculating the transverse metacentric height after the cargo has been accepted by the vessel before going to sea are presented. Formulas are derived for determining the critical zones of resonant pitching in terms of roll and trim, both in terms of the ship's speed and in the heading angle in relation to the direction of propagation of storm waves of the sea. The formulas for determining the apparent period of the ship's meeting with the wave are presented, which are the basis for calculating the resonance zones. The derived relations for determining the resonance zone by the speed of the vessel at a given heading angle and by the heading angle at a given speed of the vessel are presented under the condition of a known period of stormy sea waves and the heading angle of the vessel in relation to the direction of propagation of sea waves. Formulas are given for determining the amplitude of pitching under resonance conditions if the ratio of the period of natural oscillations of the vessel to the apparent period of the wave is within 0.7 - 1.3. Expressions for determining the amplitudes of roll and pitch that cause motion sickness in personnel, as well as the critical values of lateral g-forces that affect the correctness of its action, are presented.
Strategies for Maximizing Detection Rate in Radio SETI

Published: September 2021

Abstract
The Search for Extraterrestrial Intelligence (SETI) is a scientific and cultural effort seeking evidence of intelligent life beyond earth. Radio SETI observes the radio spectrum for “technosignatures” that could be produced by an advanced ET society. This work models radio SETI as an end-to-end system and focuses on narrowband intentional transmissions. We look at strategies to maximize the expected number of detections per year (DPY) of search. Assuming that ET civilizations will be associated with star systems, we want to maximize the number of stars that may be observed at one time. Assuming a representative star density, this requires maximizing the search volume in a cone defined by the detection range and field of view (FOV). The parameter trades are modified from the case where one simply maximizes the signal-to-noise ratio. Instead, a joint optimization between FOV and sensitivity is needed. Some implications: (1) Instead of focusing on the terrestrial microwave window of 1–10 GHz, frequencies below 1 GHz may be optimal for detection rate due to the larger FOV. (2) Arrays of smaller dishes should be favored compared to a single dish of equivalent area. (3) Aperture arrays are desirable due to their large potential FOV. Many radio telescopes under development will provide both high sensitivity and large FOV, and should offer much improved SETI detection rates. Still higher DPY is needed, however, to achieve results in reasonable time horizons, which should be possible by greatly expanding computation capability to the next-generation wide-FOV antenna arrays.
Coherent Emission from QED Cascades in Pulsar Polar Caps
Authors: Cruz Fábio , Grismayer Thomas , Chen Alexander Y. , Spitkovsky Anatoly , Silva Luis O. 
Published: September 2021

Abstract
Pulsar magnetospheres are thought to be filled with electron–positron plasma generated in pair cascades. The driving mechanism of these cascades is the emission of gamma-ray photons and their conversion into pairs via quantum electrodynamics (QED) processes. In this work, we present 2D particle-in-cell simulations of pair cascades in pulsar polar caps with realistic magnetic field geometry that include the relevant QED processes from first principles. Our results show that, due to variation of magnetic field curvature across the polar cap, pair production bursts self-consistently develop an inclination with respect to the local magnetic field that favors the generation of coherent electromagnetic modes with properties consistent with pulsar radio emission. We show that this emission is peaked along the magnetic axis and close to the polar cap edge and may thus offer an explanation for the core and conal components of pulsar radio emission.
