The effect of different climatic conditions on the decomposition of wood by fungi and the interaction between fungal populations
Authors: Ren Yikang , Wang Chen , Li Huiying 
Published: July 2021

Abstract
This article mainly explores the process of decomposing wood that simulates the fungal community. Under the conditions of a given environmental temperature and humidity, the relationship between the decomposition rate of the fungus and the growth rate, moisture resistance, environmental temperature and humidity of the fungus is obtained. In the Logstic model, a competitive resistance term was introduced to describe the interaction between fungal communities. In the end, we get: The interaction between communities will mainly make the community evolve in two directions: multiple populations coexist and a single species survives. Community evolution is more sensitive to changes in humidity, while changes in temperature have a significant impact on the decomposition rate of fungal communities.. And through the analysis of climatic conditions in different regions, it is obtained that the fungal community prefers warm and humid environments. The diversity of the population causes the fungus community to have stronger resistance and resilience. The slow growth rate of the fungus will make the community more adaptable, and it also leads to the reduction of the overall decomposition efficiency of the community.

Published: July 2021

Abstract
The global carbon cycle is an important part of the earth’s life activities, and fungi play a very important role as an important participant in the earth’s carbon cycle. We used the Monod model combined with the Lotka-Volterra model to establish a model of the fungal degradation rate under the action of various fungi by studying the decomposition of the ground litter and wood fiber by fungi. We found that the degradation rate is very long when the ground litter and wood fiber are sufficient. After time, it will enter the dynamic balance and basically will not change. This is also an important reason for verifying that the earth carbon cycle can be stable for tens of thousands of years.

Abstract
To analyse the dynamic changes of the microbial community and biodiversity in potato liquor, this experiment uses potato and corn as raw materials and uses solid fermentation method to obtain potato liquor to brew liquor. The fermentation of the 1st, 3rd, 5th, 7th, 9th, 11th, 13th and 15th days of wine samples and sent for inspection. The results show that potato liquor brews wine in the fermentation process, the bacterial community is more than fungi, and in the end of fermentation is mainly played by bacteria. Lactobacillus and Weissella accounted for the largest proportion of lactobacillus and Weissella, and found that the number of Lactobacillus (Lactobacillus) increased as fermentation progressed, but the number of Weissella continued to decrease. In the fungal community, the abnormal Wickerham yeast and the false silk yeast genus (Candida) account edged the largest proportion of the entire fermentation process. Aspergillus, on the other hand, plays a role in the early fermentation phase.

Effect of calcium addition on phosphorus removal of the submerged plant for ecological environment protection
Authors: Wang Wenqin , Hu Yukai , Liu Xiao 
Published: July 2021

Abstract
Submerged plants can create a suitable microenvironment for calcium and phosphorus co-precipitation (CaCO3-P) to further enhance the removal of phosphorus from the water column. To investigate the effect of calcium addition on the phosphorus removal in water bodies of submerged plants, this paper used Elodea nuttallii as a research object and monitord the phosphorus content in water column, sediment, plants and water environmental factors. The results showed that the addition of calcium was more effective in removing phosphorus than the group without calcium, and the final phosphorus content was controlled at a lower level; the effect of the calcium group on the phosphorus content of sediment was greater, and the addition of calcium promoted the increase of calcium-phosphorus content in the sediment. Moreover, the phosphorus content in the plant of the calcium group was higher than the plant group. It is clear that the addition of calcium ions contributed to both the removal of phosphorus from the water column and the enrichment of phosphorus by the plants.

Analysis of the Structure of Heat Losses from Buildings and Benefits of Thermal Insulation Systems
Authors: Macek D , Kosina M 
Published: July 2021

Abstract
The sources of energy are finite and are often found in unstable regions of the world, and we cannot assume at present that heat will be cheaper. Hence, and not only for these reasons, the issues of heat losses from buildings must be addressed. The paper investigates the issues of heat losses from buildings and analyses the benefits of thermal insulation of buildings. The thermal insulation of a building reduces the leakage of heat during the heating season and brings about savings in heat consumption amounting to tens of percent. In addition, when a building is insulated, the heating season may start later and end earlier. Typical thermal insulation technical modifications include the insulation of external walls, replacement of windows, roof insulation, insulation of the ceiling under the attic and above the cellar. Reducing the leakage of heat will reduce its consumption in heating and thus also cuts down air pollution with emissions produced by heating. The benefits of thermal insulation are in the economic, as well as technical sphere of building operation. The study compares the structure of heat losses and heat gains of apartment buildings from the 1970s, both in the insulated and uninsulated version, with houses complying with the current required standards and houses complying with the current recommended standards.

Abstract
The cities around the world face challenges with the shortage of land and increased demand for housing. Limit the land use for area development might resolve urban land scarcity problems. In this case, the efficiency of land use and microhome has seen as space-saving solutions. The research discusses home term on micro-scale through spatial concept design approaches. The study uses the qualitative method that interpreted by various schematic drawings. Each approach will affect the building envelopes as well as increase the home quality. The finding shows that the building envelope might be seen as inseparable attributes, consist of one or more elements; roof, wall and window, secondary skin or floor, functions as complementary attributes or a direct response to the context. This paper is an initial study to generate microhome spatial quality by using the building envelope.
Review on ZnO-based piezotronics and piezoelectric nanogenerators: aspects of piezopotential and screening effect
Authors: Pandey Rajiv Kumar , Dutta Jit , Brahma Sanjaya , Rao Bruno , Liu Chuan-Pu 
Published: July 2021

Abstract
Among various piezoelectric materials, ZnO has attracted a great deal of attention due to facile preparations and exceptional semiconductor characteristics compared to other conventional piezoceramics or organic piezoelectric materials. One of the issues hindering ZnO from progressing into applications is the screening effect, where the intrinsic piezopotential generated upon mechanical deformations is screened and becomes waned or even diminished by the presence of intrinsic free carriers in ZnO. Consequently, ZnO-based piezoelectric devices often suffer from low output voltages, resulting in low total output power generation even though the output current could be larger than those made of insulating piezoelectric materials, such as PZT, polyvinylidene fluoride, and barium titanate. It is therefore vital to fully understand the impact of the screening effect and produce strategies to handle this issue in the context of piezotronics and piezoelectric nanogenerators (PENG). Therefore, this article presents a comprehensive review of growth methodologies for various ZnO nanostructures, structure modifications, effects of free carriers on the screening effect and strategies for device applications, including strain-gated transistors, PENG and piezotronic sensors for gas, humidity and bio-molecules etc.
The scope of the All-Subjected Principle: On the logical structure of coercive laws
Authors: Abizadeh Arash 
Published: July 2021

Abstract
According to the democratic borders argument, the democratic legitimacy of a state's regime of border control requires granting foreigners a right to participate in the procedures determining it. This argument appeals to the All-Subjected Principle, which implies that democratic legitimacy requires that all those subject to political power have a right to participate in determining the laws governing its exercise. The scope objection claims that this argument presupposes an implausible account of subjection and hence of the All-Subjected Principle, which absurdly implies that all domestic laws subject foreigners to their requirements. I argue that this objection misconstrues the logical structure of the legal requirements enshrined in domestic laws: domestic laws typically enshrine narrow-scope, not wide-scope, legal requirements. To be sure, some state laws do subject foreigners to their requirements, and the All-Subjected Principle conditions democratic legitimacy on granting foreigners some say in determining them. But the best reading of the Principle does not have such general expansionary implications.
tsRNAsearch: a pipeline for the identification of tRNA and ncRNA fragments from small RNA-sequencing data
Authors: Donovan Paul D , McHale Natalie M , Venø Morten T , Prehn Jochen H M 
Published: July 2021

Abstract

Motivation
tRNAs were originally considered uni-functional RNA molecules involved in the delivery of amino acids to growing peptide chains on the ribosome. More recently, the liberation of tRNA fragments from tRNAs via specific enzyme cleavage has been characterized. Detection of tRNA fragments in sequencing data is difficult due to tRNA sequence redundancy and the short length of both tRNAs and their fragments.

Results
Here, we introduce tsRNAsearch, a Nextflow pipeline for the identification of differentially abundant tRNA fragments and other non-coding RNAs from small RNA-sequencing data. tsRNAsearch is intended for use when comparing two groups of datasets, such as control and treatment groups. tsRNAsearch comparatively searches for tRNAs and ncRNAs with irregular read distribution profiles (a proxy for RNA cleavage) using a combined score made up of four novel methods and a differential expression analysis, and reports the top ranked results in simple PDF and TEXT files. In this study, we used publicly available small RNA-seq data to replicate the identification of tsRNAs from chronic hepatitis-infected liver tissue data. In addition, we applied tsRNAsearch to pancreatic ductal adenocarcinoma (PDAC) and matched healthy pancreatic tissue small RNA-sequencing data. Our results support the identification of miR135b from the original study as a potential biomarker of PDAC and identify other potentially stronger miRNA biomarkers of PDAC.

Inter- and intra-specific variation in hair cortisol concentrations of Neotropical bats
Authors: Sandoval-Herrera Natalia I , Mastromonaco Gabriela F , Becker Daniel J , Simmons Nancy B , Welch Kenneth C 
Published: July 2021

AbstractQuantifying hair cortisol has become popular in wildlife ecology for its practical advantages for evaluating stress. Before hair cortisol levels can be reliably interpreted, however, it is key to first understand the intrinsic factors explaining intra- and inter-specific variation. Bats are an ecologically diverse group of mammals that allow studying such variation. Given that many bat species are threatened or have declining populations in parts of their range, minimally invasive tools for monitoring colony health and identifying cryptic stressors are needed to efficiently direct conservation efforts. Here we describe intra- and inter-specific sources of variation in hair cortisol levels in 18 Neotropical bat species from Belize and Mexico. We found that fecundity is an important ecological trait explaining inter-specific variation in bat hair cortisol. Other ecological variables such as colony size, roost durability and basal metabolic rate did not explain hair cortisol variation among species. At the individual level, females exhibited higher hair cortisol levels than males and the effect of body mass varied among species. Overall, our findings help validate and accurately apply hair cortisol as a monitoring tool in free-ranging bats.
Open and closed surgical exposure of palatally displaced canines: a cost-minimization analysis of a multicentre, randomized controlled trial
Authors: Björksved Margitha , Ryen Linda , Lindsten Rune , Bazargani Farhan 
Published: July 2021

Summary

Objective
To evaluate the costs of open and closed surgical exposure and subsequent orthodontic treatment for the correction of palatally displaced canines (PDCs).

Trial design
A multicentre, two-arm parallel group randomized controlled trial.

Methods
One hundred twenty adolescents between 9 and 16 years of age, from three orthodontic specialist centres, were randomized to one of the two surgical exposure interventions. The randomization was conducted according to a two-arm parallel group 1:1 allocation ratio, using computerized lists with block randomization. In both the surgical techniques, whole mucoperiosteal flaps were raised, and bone covering the PDCs was removed. In the open technique, glass ionomer was built up on the PDC crown – reaching above the mucosa through a hole punched in the flap – to allow the canine to erupt autonomously. After eruption, the canine was orthodontically moved above the mucosa. In the closed technique, an eyelet was bonded onto the PDC, the flap was repositioned and the canine was orthodontically moved beyond the mucosa. The trial ended when the PDC was successfully aligned in the dental arch.
Cost analysis was performed including costs for surgery, orthodontic treatment, emergency visits, and material, as well as costs for transports and time spent in connection with every appointment.

Blinding
Patients and caregivers could not be blinded due to obvious limitations of the clinical setting, while outcome assessors and data analysts were blinded.

Results
A cost-minimization analysis was performed since both exposure groups succeeded equally well in terms of treatment effects. The two different surgical exposures and following orthodontic treatments did not differ significantly in terms of costs.

Generalizability and limitations
Costs are estimated in the Swedish setting, which needs to be considered if applying the results in other settings. Calculations of total cost do not include finishing, debonding, retention, and follow-up.

Conclusion
There is no significant difference in costs between closed and open surgical exposure with following orthodontic treatments in PDCs.

Development of a prebiotic blend to influence in vitro fermentation effects, with a focus on propionate, in the gut
Authors: Collins Sineaid M , Gibson Glenn R , Kennedy Orla B , Walton Gemma , Rowland Ian , Commane Daniel M 
Published: July 2021

ABSTRACT
Short chain fatty acids (SCFAs) derived from the human gut microbiota, and in particular propionate, may beneficially influence metabolic processes such as appetite regulation. Development of prebiotics that induce high propionate levels during fermentation is desirable. A total of 11 candidate prebiotics were screened to investigate their fermentation characteristics, with a focus on propionate production in mixed anaerobic batch culture of faecal bacteria. Further to this, a continuous 3-stage colonic fermentation model (simulating the human colon) was used to evaluate changes in microbial ecology, lactate and SCFA production of three 50:50 blends, comprising both slow and rapidly fermented prebiotics. In mixed batch culture: xylo-oligosaccharide, polydextrose and α-gluco-oligosaccharide were associated with the greatest increase in propionate. Polydextrose, α-gluco-oligosaccharide, β-1,4 glucan and oat fibre induced the greatest reductions in the acetate to propionate ratio. The most bifidogenic prebiotics were the oligosaccharides. Fermentation of a 50:50 blend of inulin and arabinoxylan, through the continuous 3-stage colonic fermentation model, induced a substantial and sustained release of propionate. The sustained release of propionate through the colon, if replicable in vivo, could potentially influence blood glucose, blood lipids and appetite regulation, however, dietary intervention studies are needed. Bifidogenic effects were also observed for the inulin and arabinoxylan blend and an increase synthesis of butyrate and lactate, thus indicating wider prebiotic potential.
