Authors: Li Yuping 
Published: November 2020

Abstract
Air temperature has a significant impact on human thermal sensation. It directly affects the heat exchange between the human body and the environment. It is the most important factor in the PMV index that affects human thermal sensation. Clothing thermal resistance is also one of the factors that affect human thermal sensation PMV. In the operating room of a hospital building, because the clothing of the operating staff is different from that of the ordinary office environment staff, the corresponding clothing has different thermal resistance values, which will directly affect the design temperature setting of the operating room. Close to the comfort zone, when wearing surgical gowns, through Matlab programming, the relationship between the PMV value in the operating room and the indoor set temperature and air flow rate is explored in detail, in order to improve the working environment of the operating room personnel and the energy saving of the operating room air conditioning system Provide a reasonable basis.

Published: November 2020

Abstract
In order to improve workability and strength of new high water materials, the influence of silica fume and nanometer on the physical and mechanical properties of high water materials was studied. By changing the content of silica fume or gas-phase nano-SiO2 in the new high-water materials, the workability of the materials was observed, and the strength of the materials at different ages was measured. The results showed that the increase of nano-SiO2 content significantly shortened the coagulation time of the high-water materials and improved the cohesion of the high-water materials. When the water-cement ratio was 1:1, the optimal content of silica fume was 3%, and the strength of the specimen in seven days was 43.7% higher than that of the original high-water material. At the water-cement ratio of 1.5:1, the optimal content of nano-SiO2 was 2%, and the strength of the specimen in seven days was 21.2% higher than that of the original high-water material. Through SEM scanning the microstructure of the material, it was found that the hydration reaction of the high-water material with nano-sio2 was more sufficient and the structure was denser.

Analysis on the influencing factors of Shear lag effect of Double-sided Box Girder
Authors: Zhou Jingwen , He Shufa , Wu Zhida 
Published: November 2020

Abstract
In order to research different width-span ratio and aspect ratio on shear lag effect of double-sided box girder, the simple supported and cantilever systems are taken as research object. Simulating the shear lag effect is based on the finite element analysis software ANSYS. The conclusions of research are as follows: when width-span ratio η is 0.25∼0.5, the shear lag effect of the main beam varies the most under uniformly distributed load. With width-span ratio decreasing, the normal stress distribution tends to be more uniform. When aspect ratio decreases, the shear lag effect of double-box beam decreases gradually, but the variation amplitude is not big. Compared with aspect ratio, width-span ratio has a greater influence on the shear lag coefficient of double-sided box girder.
Influence of Loading Parameters of Mixed Charge on Ballistic Performance
Authors: Feng Qunshan , Chen Shanshan , Ma Yan , Nan Fengqiang , Du Pin , Liao Xin 
Published: November 2020

Abstract
In order to study the influence of loading parameters of mixed charge on its trajectory performance, the classical internal trajectory optimization model is adopted to control the consistency of other conditions and regularly change the shape, main charge quantity, arc thickness of main charge and arc thickness of auxiliary charge in mixed charge to calculate the internal trajectory performance data. When the main charge weight is 1780g, the arc thickness of the main charge is 1 mm, and the arc thickness of the auxiliary charge is 0.48mm, the data changes of the ballistic performance with the other three variables are analyzed. The results show that the influence of the main charge arc thickness of the corresponding step length on the ballistic properties of the mixed charge is more obvious than that of the main charge quantity and the auxiliary charge arc thickness of the corresponding step length. The increase of arc thickness will lead to the decrease of muzzle velocity, the decrease of bore pressure and the increase of relative combustion position of gunpowder. The increase of charge volume will lead to the increase of muzzle velocity, the increase of bore pressure and the decrease of the end position of gunpowder combustion velocity. Compared with porous powder, tubular powder has higher initial velocity, smaller gunpowder end position and higher bore pressure.
How religion has changed
Authors: Tweed Thomas A. 
Published: November 2020

Abstract
“How religion has changed,” looks at how the past shapes the present, and how responsible citizenship today requires some sense of history. Too often public discussions of the religious dimensions of policy issues either overlook the past or highlight recent years. But this shortened perspective makes it difficult to see what is new and what is not—and which problems, like climate change, economic inequality, and interreligious violence, are entangled in a longer past. Religion emerged long ago and has played a role in some of the big lifeway transitions—from foraging to farming to factories. There are four altered ways of imagining (new metaphors), making (new technologies), performing (new rituals), and gathering (new communities)—and the with these, there are challenges that accompanied each new religious habitat.
Montaigne: A Very Short Introduction
Authors: Hamlin William M. 
Published: November 2020

Abstract
Montaigne: A Very Short Introduction provides an overview of Michel de Montaigne’s life, thought, and writing. This VSI situates Montaigne’s influential Essays within his lived experience. Montaigne was a member of the minor aristocracy, a judicial investigator in his youth, and a traveler in later life. He also held the office of mayor and acted as a diplomatic link in war-torn France. Montaigne explored debates and dualities that would inspire future French philosophers, comparing marriage with friendship, solitude with sociability, and the Old World with the New. As a philosopher, he is seen as an early modern skeptic, but his broad-minded approach continues to inspire writers today.
Introduction
Authors: Green Nile 
Published: November 2020

Abstract
What is global Islam, and where did it come from? The Introduction defines “global Islam” as the doctrines and practices promoted by transnational religious activists, organizations, and states during the era of modern globalization. These processes involve Africa and Asia as much as the Middle East and the West. Globalization has enabled the emergence and proliferation of many different versions of Islam, both political and expressly nonpolitical. Communications of these beliefs and ideologies have been shaped by new forms of mobility, communication, organization, and finance. Global Islam is the result of a historical process: the interplay between religion and globalization.
Long-Term Habitual Vigorous Physical Activity Is Associated With Lower Visit-to-Visit Systolic Blood Pressure Variability: Insights From the SPRINT Trial
Authors: Xu Xiaoyong , Meng Xianghong , Oka Shin-ichi 
Published: November 2020

Abstract

Background
Our work aimed to investigate the association between vigorous physical activity and visit-to-visit systolic blood pressure variability (BPV).

Methods
We conducted a post hoc analysis of SPRINT (Systolic Blood Pressure Intervention Trial), a well-characterized cohort of participants randomized to intensive (&lt;120 mm Hg) or standard (&lt;140 mm Hg) systolic blood pressure targets. We assessed whether patients with hypertension who habitually engage in vigorous physical activity would have lower visit-to-visit systolic BPV compared with those who do not engage in vigorous physical activity. Visit-to-visit systolic BPV was calculated by SD, average real variability (ARV), and SD independent of the mean (SDIM) using measurements taken during the 1-, 2-, 3-, 6-, 9-, and 12-month study visits. A medical history questionnaire assessed vigorous physical activity, which was divided into 3 categories according to the frequency of vigorous physical activity.

Results
A total of 7,571 participants were eligible for analysis (34.8% female, mean age 67.9 ± 9.3 years). During a follow-up of 1-year, vigorous physical activity could significantly reduce SD, ARV, and SDIM across increasing frequency of vigorous physical activity. There were negative linear trends between frequency of vigorous physical activity and visit-to-visit systolic BPV.

Conclusions
Long-term engagement in vigorous physical activity was associated with lower visit-to-visit systolic BPV.

The anatomy, movement, and functions of human sperm tail: an evolving mystery
Authors: Kumar Naina , Singh Amit Kant 
Published: November 2020

AbstractSperms have attracted attention of many researchers since it was discovered by Antonie van Leeuwenhoek in 1677. Though a small cell, its every part has complex structure and different function to play in carrying life. Sperm tail is most complicated structure with more than 1000 proteins involved in its functioning. With the advent of three-dimensional microscopes, many studies are undergoing to understand exact mechanism of sperm tail movement. Most recent studies have shown that sperms move by spinning rather than swimming. Each subunit of tail, including axonemal, peri-axonemal structures, plays essential roles in sperm motility, capacitation, hyperactivation, fertilization. Furthermore, over 2300 genes are involved in spermatogenesis. A number of genetic mutations have been linked with abnormal sperm flagellar development leading to motility defects and male infertility. It was found that 6% of male infertility cases are related to genetic causes, and 4% of couples undergoing intracytoplasmic sperm injection for male subfertility have chromosomal abnormalities. Hence, an understanding of sperm tail development and genes associated with its normal functioning can help in better diagnosis of male infertility and its management. There is still a lot that needs to be discovered about genes, proteins contributing to normal human sperm tail development, movement, and role in male fertility. Sperm tail has complex anatomy, with surrounding axoneme having 9 + 2 microtubules arrangement along its entire length and peri-axonemal structures that contribute in sperm motility and fertilization. In future sperm tail-associated genes, proteins and subunits can be used as markers of male fertility.

Abstract

Background
Little is known about long-term recovery from coronavirus disease 2019 (COVID-19) disease, especially in nonhospitalized individuals. In this longitudinal study we present symptoms registered during the acute phase as well as long COVID (ie, long-lasting COVID-19 symptoms) in patients from the Faroe Islands.

Methods
All consecutive patients with confirmed reverse transcription–polymerase chain reaction testing from April to June 2020 were invited to participate in this study for the assessment of long COVID. Demographic and clinical characteristics and self-reported acute and persistent symptoms were assessed using a standardized detailed questionnaire administered at enrollment and at repeated phone interviews in the period 22 April to 16 August.

Results
Of the 180 participants (96.3% of the 187 eligible COVID-19 patients), 53.1% reported persistence of at least 1 symptom after a mean of 125 days after symptoms onset, 33.0% reported 1 or 2 symptoms, and 20.1% reported 3 or more symptoms. At the last follow-up, 46.9% were asymptomatic compared with 4.4% during the acute phase. The most prevalent persistent symptoms were fatigue, loss of smell and taste, and arthralgias.

Conclusions
Our results show that it might take months for symptoms to resolve, even among nonhospitalized persons with mild illness course in the acute phase. Continued monitoring for long COVID is needed.
