Abstract
This study aims to analyze the effect of B. bassiana on O. rhinoceros larvae. The samples used were 30 healthy 3rd instar O. rhinoceros larvae weighing 10-16 gr with a body length of 7-10 cm that were obtained from the field. The study consisted of two treatments with 10 replications, namely P1 (2 gr B. bassiana kaolin formulation/200 gr media) and P0 (Control). Observations were made every 2 days until all treated larvae was dead. The results showed that the larvae of O. rhinoceros infected with B. bassiana in the kaolin formulation died in a stiffness state and were covered with white powdery fungal hyphae on the surface of the larval body. Larvae died from B. bassiana on the 8th day after treatment and all larvae died (100%) on the 20th day after treatment. None of the O. rhinoceros larvae in the control treatment experienced death until day 20 after treatment.

Abstract
A prototype under development for the BESIII inner drift chamber upgrade is based on MAPS detectors. The detector module is the basic building and functional block of the detector prototype. Its design must meet the requirements of low material budget and high stiffness. To verify the design and quantify the performance of the detector module, a detector prototype system including five layer modules was tested at the beam facility at DESY. In order to reconstruct the 2D material budget image of the detector module, a dedicated track fitting method is developed, and the impact of multiple scattering on the track fitting is taken into account to improve the accuracy of the track reconstruction. After getting the distribution of the multiple scattering angles on the module, the material budget of the module is obtained based on the Highland formula. The test result shows that the material budget of the detector module is about 0.35 ± 0.03 (sys.)% X
0, which is consistent with the calculated value of 0.37% X
0.

Published: June 2021

Abstract
Water represents a key challenge to sustain the progress of Jordan. Providing healthy drinking water, along with current scarcity is one of the most major constraints in the water sector. This paper pursues to investigate the Spatio-temporal distribution of rainfall variability for time slice 1985-2014 over the Yarmouk River Basin (YRB) – Jordan side. Ten rainfall gauges were selected within the basin over the observation period. Applying two nonparametric statistical tests; Mann-Kendall to detect the rainfall trend in YRB, and Kolmogorov–Smirnov to detect the variations of rainfall distribution. Besides, the GIS spatial analyst tool was utilised to create interpolated rainfall map using the Thiessen polygons method. The results indicated that YRB will witness a potential decline in annual rainfall in most stations. Further, a shift in rainy season timing 2 and 58 days was observed at late in the start of the season (SoS) and 2 to 48 days for an early end of the season (EoS) on a decade’s basis accompanied by the significant uptrend in the long-term.

Published: June 2021

Abstract
Understanding Land use land cover (LULC) changes in the Kosasthalaiyar sub basin is vital for the sustainability of the watershed. Hence mapping of these changes can help visualize the spatio-temporal dynamics in the area. Remote sensing and GIS provides valuable tools to map these changes. In this present study, Remote sensing and GIS techniques has been used to prepare LULC maps for the years 1988, 1998, 2008, and 2018. The changes that has happened from 1988 to 1998, 1998 to 2008, and 2008 to 2018 has been assessed. Images from Landsat-5 and Landsat-8 Thematic Mapper (TM) have been used. Maximum Likelihood Classifier was adopted to produce the LULC maps of the watershed. Ground truth points using GPS was used to check the accuracy of the work. Five major land use classes viz; Built up land, agriculture, forest, waste land and water bodies were identified in the watershed for the study. During the 30-year period from 1988 to 2018, major changes can be observed in a number of LULC classes. About 66.05 Km2 of crop land got converted to barren land. Out of 588.86 Km2 of crop land only 176.99 Km2 remained unchanged. About 119.94 Km2 has been converted to settlements. Settlements increased from 59.89 Km2 to 341.86 Km2. Barren land increased from 168.73Km2 to 228.59 Km2. The analysis and the results obtained can help policy makers make appropriate policies for the sustainability of the Kosasthalaiyar sub basin.

Importance of Cytochrome P450 gene family from metabolite biosynthesis to stress tolerance: A review
Authors: Laffaru Singpho N , Sharma J G 
Published: June 2021

Abstract
CYP450 short for Cytochrome P450 is an enzyme superfamily involved in catalysing numerous biochemical reactions. It is known for its involvement in diverse plant processes. CYP450 is widely distributed in the case of eukaryotes and is said to exist in all domains of living organisms including bacteria, plants as well as mammals. The enzyme of this family plays a key role in the oxidative transformation of both endogenous as well as exogenous molecules. The growth and development of the plants are affected by several biotic and abiotic stresses regularly. They downgrade the crop quality and lead to a sharp decline in the productivity of the crop. CYP plays important role in providing protection to plants against these stresses. It does that by taking an active part in various detoxification as well as biosynthetic pathways. The objective of this review is to explore the role of CYP 450 in various metabolite biosynthesis as well as tolerance to various biotic and abiotic stresses in plants. This review aims to provide a framework for further investigation of the CYP450 gene family in plants and will also provide a strong base for the characterization of their diverse role in defence mechanisms against different abiotic and biotic stress and metabolite biosynthesis.

Published: June 2021

Abstract
A characteristic feature of any plant group is the species composition. Therefore, the study of the honey productivity of a particular community is primarily ascertained by the species composition of plants and the calculation of the number of individuals of each type of melliferous plants per unit area. The number of plants is determined by laying out test plots of the studied areas. To calculate the nectar and honey productivity of associations, we use the data on the honey productivity of one plant, obtained by us as a result of research. Due to the variety of soil, climatic and natural conditions, the mountain range of the Surkhandarya region is characterized by a large variety of plant groups and their complexes. Since we did not set ourselves the task of covering all the diverse flora and vegetation of the mountains with surveys, we will restrict ourselves to those communities that play a certain role in beekeeping as a forage base, where primary melliferous plant species participate in associations.

Effects of yttrium on the microstructure, texture, and magnetic properties of non-oriented 6.5 wt% Si steel sheets by a rolling process
Authors: Qin Jing , Zhou Qingyao , Zhao Haibin , Zhao Hongjin 
Published: June 2021

Abstract
Non-oriented 6.5 wt% Si steel thin sheets with three different yttrium (Y) contents (0, 0.012, and 0.03 wt%) were prepared by hot rolling, warm rolling, intermediate annealing, cold rolling and final annealing processes. The effects of the Y content on the microstructure, texture, and magnetic properties of cold-rolled 6.5 wt% Si steel sheets were studied by optical microscopy, scanning electron microscopy, energy-dispersive x-ray spectroscopy, and electron backscattered diffraction. The results showed that the sample with 0.012 wt% Y had the lowest volume fraction of inclusions, and Y played a role in purifying steel. The final average grain size of sheets decreased upon increasing the Y content. As the Y content increased, the {100} texture continuously weakened, and the overall intensity of the η (〈100〉//RD) texture increased first and then decreased, while the intensity of the detrimental γ (〈111〉//ND) texture decreased first and then increased. Adding an appropriate amount of Y optimized the recrystallization texture by promoting the occurrence of shear bands, which provided more nucleation sites for η - fiber oriented grains. When the Y content was 0.012 wt%, the magnetic induction B
50 reached the maximum (1.64655 T) due to the enhanced η texture and weakened γ texture. The sample with 0.012 wt% Y showed the lowest core loss at high frequencies (>5 kHz) because of the favorable grain size. The addition of excess Y increased the number of inclusions and increased γ -fiber oriented grain nucleation, which deteriorated the magnetic properties of non-oriented 6.5 wt%Si steel.

Abstract
Agriculture accounts for approximately 10% of global greenhouse gas emissions and is simultaneously associated with impacts on human health through food consumption, and agricultural air pollutant emissions. These impacts are often quantified separately, and there is a lack of modelling tools to facilitate integrated assessments. This work presents a new model that integrates assessment of agricultural systems on (i) human health indirectly through dietary, obesity and malnutrition health risks from food consumption, (ii) human health directly through exposure to air pollutants from agricultural emissions, and (iii) greenhouse gas emissions. In the model, national food demand is the starting point from which the livestock and crop production systems that meet this are represented. The model is applied for 2014–2018 to assess the robustness of the GHG emissions and health burden results that this integrated modelling framework produces compared to previous studies that have quantified these variables independently. Methane and nitrous oxide emissions globally in 2018 were estimated to be 129 and 4.4 million tonnes, respectively, consistent with previous estimates. Agricultural systems were also estimated to emit 44 million tonnes of ammonia. An estimated 4.1 million deaths were associated with dietary health risks, 6.0 million with overweight/obesity, and 730 thousand infant deaths from malnutrition, consistent with previous studies. Agricultural air pollutant emissions were estimated to be associated with 537 thousand premature deaths attributable to fine particulate matter (PM2.5) exposure, and 184 thousand premature deaths from methane-induced ground-level ozone. These health impacts provide substantial opportunities to design integrated strategies that mitigate climate change, and improve human health, and also highlight possible trade-offs that the expansion of agricultural production could have due to increased emissions. The model presented here provides for the consistent evaluation of the implications of different agricultural strategies to meet food demand while minimising human health and climate change impacts.
In operando Raman and optical study of lithium polysulfides dissolution in lithium–sulfur cells with carrageenan binder
Authors: Blanchard Didier , Slagter Mark 
Published: June 2021

Abstract

In operando Raman and optical studies have been performed on lithium–sulfur (Li–S) batteries containing carrageenan binder in the sulfur cathode for chemical trapping of the polysulfides (PSs). Three different types of cells were used: coin cells, EL-cell and capillary cells to examine the PS speciation. With the coin cell we confirm the stability and cyclability of the carrageenan based Li–S cells and the improved capacity retention when compared to conventional polyvinylidene fluoride based Li–S cells. With the EL-Cell, the PS speciation at the cathode is documented but only weak evidences of the nucleophilic trapping of the PS are found. The in operando Raman and optical studies on the capillary cell revealed the dissolution and diffusion of the PS in the whole electrolyte volume. We confirm the disproportionation of S4
− into S3
− in the electrolyte. Strong inhomogeneous PS concentration in the electrolyte are found to develop in the course of the cell charge–discharge cycling which must be detrimental to the performances of the battery.
State aesthetics and state meanings: Political architecture in Ghana and Côte d’Ivoire
Authors: Gallagher Julia , Larbi Mpere Dennis , N'djoré Yah Ariane Bernadette 
Published: June 2021

Abstract
There are striking differences between state buildings in Ghana and Côte d’Ivoire and in how citizens living in each country’s capital city think and talk about them. In this article, we explore the degree to which these buildings illustrate very different ideas of statehood in West Africa. We draw on art theories from West Africa to argue that architectural aesthetics rest on juxtapositions of beauty and the sublime and we suggest ways these help establish state meaning. We then apply our aesthetic approach to citizens’ evaluations of their state buildings in Ghana and Côte d’Ivoire and illustrate how differently the approach plays out, in Ghana where the state emerges as acclimatized and relatively robust and in Côte d’Ivoire where the state emerges as idealized and fragile.
