Published: August 2021

Abstract
Micro cracks in concrete is a prevalent problem which contributes to the deterioration of concrete over the course of time. Considering the micro scale of size that these cracks possess, many developments were made in recent days where nano particles like nano-silica and other carbon nano materials like graphene which is a wonder material used to make a stronger,greener concrete are being employed in the manufacture of concrete to build resistance against these cracks and their further propagation. This paper reports the influence of graphene oxide incorporated in silica fume blended concrete at different doses the dosage of graphene oxide was 0.03% and 0.05%. Two types of mixes are developed by the inclusion of graphene oxide (GO) and silica fume (SF) which are named as SF concrete, GO in SF blended concrete; these results were compared with the conventional concrete. The current study focuses on the influence of GO Mechanical properties, XRD analysis, and Rapid Chloride Permeability Test (RCPT) is performed to measure the chloride resistance of silica fume-based graphene oxide concrete. The mechanical properties and chloride ion permeability with inclusion of 0.03% GO have shown better results compared to the other mixes. From the XRD analysis it has been noticed that the peak intensity at 26° for 0.03% GO concrete mix is higher than silica fume induced concrete mix.

Abstract
In recent scenarios, waste management is a great concern for all countries. Other side manufacturing industries of cement is produced carbon-dioxide in the environment. The utilization of industrial waste as a by-product of cement is a great opportunity for researchers. Keeping this thing in mind used industrial waste of iron factories as an alternative to cement in concrete. This investigation used waste ground granulated blast furnace slag (GGBFS) acquired from iron industries. The GGBFS used as a binder and partial cement replacing material in concrete with 1% superplasticizer and a constant 0.48 w/c ratio. GGBFS used as 2.5%, 5%, 7.5%, 10% and 12.5% in interval of 2.5% by weight of cement. Mechanical behavior evaluated in terms of compressive strength, flexural strength, and splitting tensile strength. From the results, it is detected compressive, flexural, and splitting tensile strength for GGBFS mix was better to compare to control concrete. Maximum compressive strength was achieved at 10% replacement of cement with GGBFS. Overall performance of GGBFS made concrete is satisfactory and it can be recommended for the production of sustainable concrete.

Abstract
Rice husk ash (RHA) is the promising pozzolanic material which can be used with Portland cement in a specific proportion to produce durable concrete and with reduced impact of cement industry on environment. Effect of RHA on the fresh properties (i.e., Workability) of concrete has been studied. Workability means the ease with which the concrete can be placed and compacted without segregation. Thus, to produce a high-quality concrete, its workability is very important factor. To measure the workability of concrete slump test is the most common test that is performed. This test gives the general idea that the mix prepared is harsh, or flowable. In this study, RHA was added to concrete in different proportion as a binder. Results reveals that RHA can be used as a binder in sustainable construction.

Published: August 2021

Abstract
Gravity Recovery and Climate Experiment (GRACE) satellite mission, which is dedicated specifically to the Earth’s gravity change monitoring, also can be used to observe water mass variations. GRACE data is provided through temporal mass variations, primarily water volume variations such as surface water and groundwater changes. GRACE satellite data can be obtained in monthly spherical harmonics coefficients depicting the change of surface mass density. This study investigates the effects of extreme climate change during 2016 in Indonesia by utilizing the GRACE data. Here, the surface mass density change is converted into equivalent water height (EWH). Since the amount of rainfall in Indonesia indirectly dominates the water mass variability, the EWH is then compared with the precipitation over the same period of this study. The result showed that during 2016, the highest and lowest EWH was presented in August with the highest value of 23.527 cm over the Aceh region and the lowest EWH of 0.665 cm over the Nusa Tenggara region. The most increased precipitation during 2016 is in the Kalimantan region, with a value of 0.610 mm/hr in February. The lowest one is in the Nusa Tenggara region, with a value of 0.009 mm/hr in August. For comparison with the EWH, the precipitation rates were converted into monthly precipitation in cm. The correlations between EWH and precipitations variabilities showed different results in different study zones, with the highest correlation in zone 6, which covers North Kalimantan. In comparison, the lowest correlation occurred in zone 25, which covers Yamdena and Tragan islands_ area in the Moluccas

Published: August 2021

Abstract
With the combination of 2014-2018 MODIS NDVI products and climate data (precipitation and temperature) in Inner Mongolia, China, this study aims to explore and verify the effectiveness of incorporating neighborhood association effect in vegetation index modeling. A neighborhood statistical method based on Moore neighborhood was applied to update the original spatial datasets. Geographically weighted regression (GWR) was constructed to compare the model accuracy between original data and updated data. The GWR models were tested under different neighborhood sizes (3 × 3, 5 × 5, 7 × 7, 9 × 9, and 11 × 11 Moore neighborhood sizes). Our work compared the results of different GWR models and the original GWR model that did not consider neighborhood association effect. The results indicated that considering neighborhood association effect could improve GWR model accuracy substantially. In addition, the neighborhood sizes proved to be important factors for measuring neighborhood association effect. We conclude that neighborhood association effect should be integrated to understand vegetation changing trajectory based on climate factors.

Abstract
In order to understand the changes in the ecological environment of Miyun Reservoir after the South-to-North Water Transfer Project, our study investigated the changes in the composition and structure of two indicator species in the Miyun Reservoir and applied the rotifer biological assessment method to analyse the changes of water ecological environment. Our results showed that a total of 10 species of the genera Trichocerca and Brachionus were identified during the investigation with an average annual abundance of 542.124 ind./L and 102.68 ind./L, respectively. Among them, T. pusilla and T. cylindrica were the dominant species of the genus Trichocerca, and the majority of Brachionus species were B. diversicornis, B. angularis, B. caudatus. Variance results showed that there were significant differences in the abundance of these two rotifer pupations at different inter-annual and spatial scales during the survey. The biological evaluation indicated that the water quality has gradually changed from eutrophication to oligotrophication after the South-to-North Water Transfer Project, and the ecological environment was maintained well. Our results will provide necessary ecological parameters for water environment protection and ecological safety management of Miyun Reservoir.
Can I Buy My Health? A Genetically Informed Study of Socioeconomic Status and Health
Authors: Robinette Jennifer W , Beam Christopher R , Gruenewald Tara L 
Published: August 2021

AbstractBackgroundA large literature demonstrates associations between socioeconomic status (SES) and health, including physiological health and well-being. Moreover, gender differences are often observed among measures of both SES and health. However, relationships between SES and health are sometimes questioned given the lack of true experiments, and the potential biological and SES mechanisms explaining gender differences in health are rarely examined simultaneously.PurposeTo use a national sample of twins to investigate lifetime socioeconomic adversity and a measure of physiological dysregulation separately by sex.MethodsUsing the twin sample in the second wave of the Midlife in the United States survey (MIDUS II), biometric regression analysis was conducted to determine whether the established SES-physiological health association is observed among twins both before and after adjusting for potential familial-level confounds (additive genetic and shared environmental influences that may underly the SES-health link), and whether this association differs among men and women.ResultsAlthough individuals with less socioeconomic adversity over the lifespan exhibited less physiological dysregulation among this sample of twins, this association only persisted among male twins after adjusting for familial influences.ConclusionsFindings from the present study suggest that, particularly for men, links between socioeconomic adversity and health are not spurious or better explained by additive genetic or early shared environmental influences. Furthermore, gender-specific role demands may create differential associations between SES and health.
Early Response (2018–2020) to the Threat of Spotted Lanternfly, Lycorma delicatula (Hemiptera: Fulgoridae) in Pennsylvania
Authors: Urban Julie M , Calvin Dennis , Hills-Stevenson Jillian 
Published: August 2021

Abstract
Spotted lanternfly (SLF), Lycorma delicatula (Hemiptera: Fulgoridae) is an invasive planthopper first detected in the United States in one county in Pennsylvania in September 2014. As of October 2020, 43 counties in nine states are under quarantine due to the presence of SLF in those areas, and it has been detected in 10 additional states. The greatest economic impacts from SLF have been reported from grape growers, nurseries, and Christmas tree growers, and it is considered a nuisance pest by residents. Because this insect feeds on over 70 species of herbaceous and woody trees and plants, it has the potential to cause wide ranging damage across agricultural, urban, suburban, and forested landscapes. Due to these widespread impacts, SLF management has demanded cooperation at local, state, regional, and national levels. However, the immediate response to the threat of SLF in Pennsylvania during the early phases of the infestation was a catalyst for initiating these efforts, and this response was coordinated via a partnership between the Pennsylvania Department of Agriculture, the U.S. Department of Agriculture Animal and Plant Health Inspection Service, and the Pennsylvania State University College of Agricultural Sciences. The history of SLF in the United States is recounted, highlighting the early priorities that emerged. The resulting actions taken in 2018–2020 in response to these priorities, which involved research, Extension, and public awareness are summarized, and areas in which improvements are needed that have been identified are discussed.

Published: August 2021

AbstractMost epidemiologic studies fail to capture the impact of spatiotemporal fluctuations in traffic on exposure to traffic-related air pollutants in the near-road population. Using a case-crossover design and the Research LINE source (R-LINE) dispersion model with spatiotemporally resolved highway traffic data, we quantified associations between primary pollutants generated by highway traffic—particulate matter with an aerodynamic diameter less than or equal to 2.5 μm (PM2.5), oxides of nitrogen (NOx), and black carbon (BC)—and daily nonaccidental, respiratory, cardiovascular, and cerebrovascular mortality among persons who had resided within 1 km (0.6 mile) of major highways in the Puget Sound area of Washington State between 2009 and 2013. We estimated these associations using conditional logistic regression, adjusting for time-varying covariates. Although highly resolved modeled concentrations of PM2.5, NOx, and BC from highway traffic in the hours before death were used, we found no evidence of an association between mortality and the preceding 24-hour average PM2.5 exposure (odds ratio = 0.99, 95% confidence interval: 0.96, 1.02) or exposure during shorter averaging periods. This work did not support the hypothesis that mortality risk was meaningfully higher with greater exposures to PM2.5, NOx, and BC from highways in near-road populations, though we did incorporate a novel approach to estimate exposure to traffic-generated air pollution based on detailed traffic congestion data.

Abstract

BACKGROUND
Blood pressure variability (BPV) is associated with end organ damage and cardiovascular outcomes in hypertensive patients. Prehypertensive patients frequently develop hypertension (HT). The purpose of the present study was to evaluate the effect of BPV on the development of HT.

METHODS
Two hundred and seven prehypertensive patients from the Cappadocia cohort were monitored over 2 years, and 24-hour ambulatory blood pressure monitoring (ABPM), office BP, and home BP measurements were subsequently performed at 4- to 6-month intervals. BPV was calculated as average real variability (ARV) from 24-h ABPM data, home BP, and office BP measurements at first visit. The relationship was evaluated between baseline ARV and the development of HT.

RESULTS
HT was diagnosed in 25.60% of subjects. Baseline 24-hour ABPM systolic blood pressure (SBP)ARV and diastolic blood pressure (DBP)ARV and home SBPARV were significantly higher in patients who developed HT than the other patients (P 0.006, 0.001 and 0.006, respectively). Baseline 24-hour ABPM SBPARV and home SBPARV exceeding the 90th percentile were identified as parameters affecting development of HT at logistic regression analysis.

CONCLUSION
In conclusion, our prospective observational cohort study showed that short-term BPV in particular can predict the development of HT in the prehypertensive population.
Spatial transcriptomics analysis of uterine gene expression in enhancer of zeste homolog 2 conditional knockout mice†

Published: August 2021

AbstractHistone proteins undergo various modifications that alter chromatin structure, including addition of methyl groups. Enhancer of zeste homolog 2 (EZH2) is a histone methyltransferase that methylates lysine residue 27, and thereby suppresses gene expression. EZH2 plays integral roles in the uterus and other reproductive organs. We have previously shown that conditional deletion of uterine EZH2 results in increased proliferation of luminal and glandular epithelial cells, and RNA-seq analyses reveal several uterine transcriptomic changes in Ezh2 conditional (c) knockout (KO) mice that can affect estrogen signaling pathways. To pinpoint the origin of such gene expression changes, we used the recently developed spatial transcriptomics (ST) method with the hypotheses that Ezh2cKO mice would predominantly demonstrate changes in epithelial cells and/or ablation of this gene would disrupt normal epithelial/stromal gene expression patterns. Uteri were collected from ovariectomized adult WT and Ezh2cKO mice and analyzed by ST. Asb4, Cxcl14, Dio2, and Igfbp5 were increased, Sult1d1, Mt3, and Lcn2 were reduced in Ezh2cKO uterine epithelium vs. WT epithelium. For Ezh2cKO uterine stroma, differentially expressed key hub genes included Cald1, Fbln1, Myh11, Acta2, and Tagln. Conditional loss of uterine Ezh2 also appears to shift the balance of gene expression profiles in epithelial vs. stromal tissue toward uterine epithelial cell and gland development and proliferation, consistent with uterine gland hyperplasia in these mice. Current findings provide further insight into how EZH2 may selectively affect uterine epithelial and stromal compartments. Additionally, these transcriptome data might provide mechanistic understanding and valuable biomarkers for human endometrial disorders with epigenetic underpinnings.

Abstract
We Review How Different Bat Guilds Respond To Artificial Light At Night (Alan) And Assess How The Impacts Can Vary According To Ecological Context. All Studied European Species Respond Negatively To Alan Close To Roosts And Drinking Sites, And The Impacts Occur Across A Wide Range Of Light Colors And Intensities. Most Bat Species Are Sensitive To Alan When Commuting And Foraging. Although Narrow-Space-Foraging Bat Species Consistently Avoid Alan When Foraging, Open And Edge-Space-Foraging Species May Exploit Insects Lured By Alan. Therefore, Alan Acts As An Environmental Filter On Bat Assemblages. Considering The Detrimental Effect Of Alan On Insects, We Conclude That Alan Probably Has Negative Impacts On All Bat Species, Even On Those Foraging At Streetlights. The Sprawl Of Alan May Be A Key Factor Driving The Decline Of Bat Diversity Globally, And The Current Trajectory Of Increasing Alan Is Therefore Of Considerable Concern For Bat Conservation.
