Abstract
ObjectiveThe aim of this study is to assess factors that influence the uptake of short term contraceptives among married women aged between 15-49 years in Afghanistan.MethodThe cross sectional Afghanistan 2015 Demographic and Health Survey provided the dataset for this analysis. We included 22,974 women and applied multivariable logistic regression to investigate the influencing factors for the uptake of short term contraceptives.Results95% of Afghan women knew at least one type of contraception but only 16% were using short term contraceptives. Short term contraceptive use was most prevalent among women in the age group between 30 and 40 who were educated, employed, and rich. Most of users were living in the western parts of Afghanistan and belong to Balooch and Pashtun ethnic groups. Media exposure and women empowerment were also positively associated with the use of short term contraceptives. However, we did not find an association with living in urban or rural settings.ConclusionFP in Afghanistan requires multisectoral efforts, tailored to the needs of women stemming from low and middle socioeconomic status. Health promotion activities, empowering women, strengthening education, and training of Family Planning service providers on effective counseling are good options to address the issue.

Abstract
In this paper, AlSi10Mg alloy powder is selected as the forming powder of Selective Laser Melting technology, and the AlSi10Mg alloy SLM curved surface sample is constructed by setting the internal and external layering parameters. In view of the relatively rough surface roughness of SLM technology molded parts, this paper selects the magnetic finishing technology with higher flexibility characteristics to perform surface finishing and finishing on the formed curved surface samples. Explore the feasibility of magnetic finishing technology on the finishing of SLM shaped curved parts, and test and analyze the surface roughness, surface hardness and hydrophobicity of the finishing permanent magnet tools and the curved surface samples before and after finishing. Finally, it was found that the use of a 75° trapezoidal slotted permanent magnet finishing tool to absorb spherical Al2O3 magnetic abrasives for flexible finishing of AlSi10Mg alloy SLM shaped curved surface samples can achieve better finishing results.In this paper, the orthogonal experiment method is used to optimize the finishing experiment. It is found that the finishing parameters of the spindle speed is 1800 r/min, the feed rate is 5 mm/min, the gap is 2 mm, and the abrasive consumption is 7g to form the AlSi10Mg alloy SLM. The surface roughness Ra=0.279μm can be obtained by magnetic finishing of the curved sample, and the surface morphology of the sample has been greatly improved. At the same time, it is found that the magnetic finishing technology improves the surface roughness of the AlSi10Mg alloy SLM forming surface sample, while it does not change the surface hardness of the sample, but it can significantly improve the hydrophobicity of the sample surface.

Abstract
The origin of fast radio bursts (FRBs), millisecond-duration flashes of radio waves that are visible at distances of billions of light-years, remains an open astrophysical question. Here we report the detection of the multi-component FRB 20191221A with the Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst Project (CHIME/FRB), and the identification of a periodic separation of 216.8(1) ms between its components with a significance of 6.5 sigmas. The long (~ 3 s) duration and nine or more components forming the pulse profile make this source an outlier in the FRB population. We also report two additional FRBs, 20210206A and 20210213A, whose multi-component pulse profiles show some indication of periodic separations of 2.8(1) and 10.7(1) ms, respectively, suggesting the possible existence of a group of FRBs with complex and periodic pulse profiles. Such short periodicities provide strong evidence for a neutron-star origin of these events. Moreover, our detections favour emission arising from the neutron-star magnetosphere, as opposed to emission regions located further away from the star, as predicted by some models. Possible explanations for the observed periodicity include super-giant pulses from a neutron star that are possibly related to a magnetar outburst and interacting neutron stars in a binary system.
Phyllobacterium Calauticae Sp. Nov. Isolated From a Microaerophilic Veil Transversed by Cable Bacteria in Freshwater Sediment

Published: July 2021

Abstract
Microaerophilic veils of swimming microorganisms form at oxic-anoxic interfaces, most commonly described in sediments where sulfide diffusing out from below meets oxygen diffusing in from the water phase. However, distinctive microaerophilic veils form even when there is a gap between the sulfide and O2 fronts, i.e., a suboxic zone, and suggest that the organisms inhabiting these veils can use electron donors other than sulfide. Suboxic zones are found for example in sediment where cable bacteria spatially separate sulfide and O2 by up to several centimetres. Here we describe the extraction of microorganisms from a microaerophilic veil that formed in cable-bacteria-enriched freshwater sediment using a glass capillary, and the subsequent isolation of a motile, microaerophilic, organoheterotrophic bacterium, strain R2-JLT, unable to oxidize sulfide. Based on phenotypic, phylogenetic, and genomic comparison, we propose strain R2-JLT as a novel Phyllobacterium species, P. calauticae sp. nov.. The type strain is R2-JLT (=LMG 32286T =DSM 112555T). This novel isolate confirms that a wider variety of electron donors, including organic compounds, can fuel the activity of microorganisms in microaerophilic veils.

Authors: Drøjdahl Ryg Nina , Gram Jeppe , Haghighi Maryam , Juhl Claus Bogh 
Published: July 2021

OBJECTIVE
We investigated the effects of replacing regular outpatient follow-up through prescheduled visits with patient-initiated visits on patient satisfaction and clinical variables of type 1 diabetes (T1D).

RESEARCH DESIGN AND METHODS
A 24-month randomized controlled trial in which adults with T1D were allocated to either patient-initiated unlimited access to outpatient visits or usual care through regular prescheduled visits. The primary outcome was seven patient-reported experience measures of patient satisfaction focused on benefit of consultation and accessibility of the outpatient clinic. Secondary outcomes included clinical variables of diabetes and use of staff resources.

RESULTS
We enrolled 357 outpatients (intervention, n = 178; control, n = 179). After 24 months, participants in the intervention group experienced more benefit from consultations compared with baseline within groups (P &lt; 0.05) and fewer unnecessary visits compared with control subjects (P &lt; 0.05). Patient needs covered and satisfaction with the outpatient clinic were high and unchanged in both groups, and accessibility was increased (three questions, all P &lt; 0.05). A calculated 7-item patient satisfaction sum score favored the intervention group over control subjects (P &lt; 0.001). There were no significant changes in glycated hemoglobin (HbA1c), LDL, blood pressure, and complication status. The mean number of outpatient visits over 24 months (± SD) was lower in the intervention group compared with control subjects (4.4 ± 2.8 vs. 6.3 ± 2.7; P &lt; 0.001), while the number of telephone contacts was higher (3.1 ±3.4 vs. 2.5 ± 3.2; P &lt; 0.001).

CONCLUSIONS
Patient satisfaction remained high or improved with patient-initiated on-demand use of the diabetes outpatient clinic, with no decline in the quality of diabetes care, and a reduction in the use of staff resources.

Published: July 2021

Abstract
This article first introduces neural networks and their characteristics. Based on a comparison of the structure and function of biological neurons and artificial neurons, it focuses on the structure, classification, activation rules, and learning rules of neural network models. Based on the existing literature, this article adds a distributed time lag term of the neural network system. In the actual problem, history has a very important influence on the current change situation, and it is not only at a specific time in the past. It has an impact on the current state change rate. Therefore, based on the existing literature that only has discrete time lags, this paper adds distributed time lags. Such neural network systems can better reflect real-world problems. In this paper, we use three different inequality scaling methods to study the existence, uniqueness, and global asymptotic stability of a class of neural network systems with mixed delays and uncertain parameters. First, using the principle of homeomorphism, a new upper-norm norm is introduced for the correlation matrix of the neural network, and enough conditions for the existence of unique equilibrium points in several neural network systems are given. Under these conditions, the appropriate Lyapunov is used. Krasovskii functional, we prove that the equilibrium point of the neural network system is globally robust and stable. Numerical experiments show that the stability conditions of the neural network system we obtained are feasible, and the conservativeness of the stability conditions of the neural network system is reduced. Finally, some applications and problems of neural network models in psychology are briefly discussed.

Published: July 2021

Abstract
Lateral compact spinning with pneumatic groove is a spinning process to gather fibers by common actions of airflow and mechanical forces. Compared with ring spinning, it can more effectively reduce yarn hairiness and enhance yarn strength. However, fiber motion in the agglomeration area is complex. And, it is important to establish a new fiber model to accurately describing the fiber motion. The objectives of this research were to create a new fiber model to simulate the agglomeration process, to analyze yarn properties of the lateral compact spinning with pneumatic groove, and to compare with other spinning yarns through a series of tests. The new fiber model was based on the finite element method implemented in MATLAB and was to show the fiber motion during the agglomeration area. The simulation generated results were close to the real motion of fibers in spinning. In the lateral compact spinning with pneumatic groove, fiber bundle through the agglomeration area can be gathered, and the output of the fiber bundle was nearly to cylinder before yarn twisted. The experiments demonstrated that the lateral compact spinning with pneumatic groove can improve the yarn properties: increase the yarn twist, enhance the yarn strength, and reduce the yarn hairiness.

Published: July 2021

Abstract
The aim of this work is to estimate the effect of loop length and Lycra weight percent (Lwp) on the geometrical and thermo-physiological comfort of elastic plain knitted fabric. Fifty single jersey knitted fabric samples were produced at five levels of Lycra weight percent (Lwp) (4%, 5%, 6%, 7%, and 8%) and loop length (2.7 mm, 2.9 mm, 3.1 mm, 3.3 mm, and 3.4 mm) with full plaited (fp) and half plaited (hp) of bare Lycra. The thermo-physiological comfort properties (thermal conductivity, absorptivity, and water vapor permeability), air permeability, and geometrical properties were measured at standard of each one. The results showed that the elastic single jersey knitted fabric thickness ranged between 3.12 times and 4.2 times of the yarn diameter (d). The fabric thickness increased when loop length is increased and decreased when Lwp is increased. The thermal conductivity, absorptivity, and water vapor resistance (WVR) decreased with Lwp increasing.

Published: July 2021

Abstract
The study investigates retroreflective fabrics’ efficiency from the point of view of the interaction of their visibility, thermo-physiological comfort properties, and durability (represented by physical-mechanical performance). The effect of the combination of two production technologies (reflective transfer films and screen printing method) and two reflector covering sizes (25% and 85%) was examined. Technique for order of preference by similarity to ideal solution (TOPSIS) method was used to determine the best solution considering the abovementioned tested categories of properties. Retroreflective performance was in congruence with the used design coverage factor of the tested pattern. It was found that retroreflection of the tested pattern produced using screen printing technology was significantly lower than retroreflection of an identical pattern made by a transfer film. On the contrary, in terms of thermo-physiological comfort and physical-mechanical performance of the tested samples, screen printing technology shows significantly better results in almost all tested properties, especially in water vapor permeability, moisture management, and physical-mechanical performance. The solution for the abovementioned contradictory results can be achieved by using a combination of the advantages associated with each of these technology methods. Screen printing can be applied to specific regions of clothing that are exposed to extreme loading or sweating, and the transfer of film elements ensures high visibility with respect to the standards and biomotion principles that are deployed as prevalent benchmarks in the industry.

Abstract
This study investigated the effects of dietary inclusion of grape seed meal (GSM) on antioxidant markers in kidney of aflatoxin B1 fed pigs. Twenty-four cross-bred pigs (TOPIG-40) were randomly assigned to one of the four experimental diets: control (Control), aflatoxin B1 (diet contaminated with 320 μg AFB1/kg feed), grape seed meal (diet with 8% GSM) and AFB1+GSM (320 μg AFB1/kg feed + 8% GSM) for 30 days. Aflatoxin B1 induced oxidative damage and showed lower antioxidant status in kidney after 30 days. CAT and SOD activity measured in kidneys revealed significant differences when comparing the GSM+AFB1 group with the AFB1 group. Additionally, GSM diet alone did not affect CAT and SOD levels in kidneys of piglets compared with the control group, suggesting that they are maintained at physiological levels. We did not detect any effects of GSM on GPx and TAS. Including GSM into piglets’ diet significantly lowered lipid peroxidation induced by AFB1, while it did not affect it compared with the control group. The present study demonstrated the ability of GSM to alleviate the effects induced by the toxin evidenced by the improvement in the antioxidant status, and suggests the potential applicability of GSM as mycotoxin adsorbent in animal feed.

Abstract
Genetic parameters are important in breeding program of sheep. For the genetic evaluation of sheep was used the random regression test-day animal model. This model was better economic that another models because reduces generation interval and reduces the costs with test-days records. Data consisted of 1050 test-day of 403 ewes in first year (2017), 752 test-day of 374 ewes in second year (2018) and 1164 test-day of 319 ewes in third year (2019). The main goal to achieve the objectives of this research were the estimation of the genetic parameters important in obtaining the breeding value by calculation heritability for test-day milk yields and the correlations between test-days milk yields, for Teleorman Black Head Sheep population from Teleorman county in three different years. The heritability for test-day milk yield ranged from 0.150 to 0.237 in 2017, from 0.212 to 0.600 in 2018 and in 2019 from 0.186 to 0.403. Genetic correlations between sheep test-days milk yield in 2017 were positive and high.
