Abstract
A large quantity of sediments is dredged continuously worldwide. They are generally dumped in landfill areas which ensue in the increasing cost of the dredging operations and in soil-groundwater pollution. The objective of this work is to study the beneficial reuse of dredged sediments in foam mortar and particularly by studying the influence of the substitution of sand by dredged sediments. Air foam mortars/concrtes is an alternative to ordinary concrete, which presents the advantages of lightweight and low thermal conductivity. In this study, the density required ranges from 1200kg/m3 to 1600kg/m3 to the development of foam concrete building blocks and slabs for load-bearing and non-load-bearing structures. Twenty foam mortar mixes were prepared. Sediments were introduced by replacing 15%, 30%, and 50% mass of the sand. The foam percentage was introduced from 0–100% volume of mortar. Workability, compressive strength, and flexural strength at the age of 7, 28, and 60 days were monitored. The size distribution of foam bubbles and the effect of sediments on their stability is also studied. The results demonstrate that sediment has a good general effect on foam concrete and this opens up very promising new types of concretes. However, for a high substitution rate, a decrease in performances is denoted.

Abstract
A solution processed top-contact bottom gated SnO2 thin-film transistor (TFT) has been fabricated by using a TiO2/ Li-Al2O3 bilayer stacked gate dielectric that show operating voltage of this TFT within 2.0 V. It is observed that the bilayer dielectric has much higher areal capacitance with lower leakage current density that significantly improve the overall device performance of TFT. The TFT with bilayer gate dielectric shows an effective carrier mobility (µsat) of 9.2 cm2V− 1s− 1 with an on/off ratio of 7.1x103 which are significantly higher with respect to the TFT with a single layer Li-Al2O3 gate dielectric. The origin of this improvement is due to the Schottky junction between the highly doped silicon (p++-Si) and TiO2 of bilayer stacked dielectric that induced electrons to the channel which reduces the dielectric/semiconductor interface trap state. This investigation opens a new path to develop TFT device performance using a suitable bilayer stack of gate-dielectric.

Abstract
This paper intends to explore rice yield fluctuations to large-scale atmospheric circulation indices (LACIs) in Bangladesh. The annual dataset of climate-derived yield index (CDYI), estimated using principal component analysis of Aus rice yield data of 23 districts, and five LACIs for the period 1980-2017 were used for this purpose. The key outcomes of the study were as follows: (1) three sub-regions of Bangladesh, northern, northwestern, and northeastern, showed different kinds of CDYI anomalies; (2) the CDYI time series in northern and northeastern regions exhibited a substantial 6-year fluctuation, whereas a 2.75 to 3-year fluctuation predominated the northwestern region; (3) rice yield showed the highest sensitivity of LACIs in the northern region; (4) Indian Ocean dipole (IOD) and East Central Tropical Pacific SST (Nino 3.4) in July, and IOD index in March provide the best yield forecasting signals for northern, northwestern, and northeastern regions, respectively; (5) wavelet coherence study demonstrated noteworthy in-phase and out-phases coherences between key climatic variables (KCVs) and CDYI anomalies at various time-frequencies in three sub-regions; (6) the random forest (RF) model revealed the IOD as the vital contributing factor of rice yield fluctuations in the country; (6) the multi-factorial model with different LACIs and year as predictors can predict rice yield, with the mean relative error (MRE) in the range of 4.82 to 5.51% only. The generated knowledge can be used for an early assessment of rice yield and recommend policy directives to ensure food security.

Abstract
The manufacturing sector is the backbone for the development of an economy. Numerous studies investigate the impact of aggregative energy consumption on environmental degradation by using typical econometric techniques. To correct this gap our study uses energy consumption and environmental degradation only in the manufacturing sector of Pakistan for the period 1985 to 2018. Our study also demonstrates the symmetric and asymmetric behaviour of energy consumption with carbon emissions by using a recently developed methodology byShin et al. (2014).The linearARDL result shows energy consumption and financial development intensifies environmental degradation. While FDI and globalization mitigate environmental sustainability also the results validate pollution halo hypotheses in Pakistan. However, nonlinear ARDL results confirm theasymmetric behaviour of energy consumption with co2 emission. This study employs implications for policymakers in Pakistan to consider asymmetric behavior of energy consumption as well as the installation of renewable energy sources and technological improvements in the industrial sector need to mitigate environmental sustainability. Further, there is a need to enhance globalization and FDI for Pakistan to achieve its environmental targets.

Published: May 2021

Abstract
Vacancies occur naturally in all crystalline materials. A vacancy is a point defect in a crystal in which an atom is removed at one of the lattice sites. The defect could be imported during the synthesis of the material or be added by defect engineering. In this paper by employing the density functional theory as well as the non-equilibrium Green’s function approach, the structure and electronic properties of the perfect and defected BN nanosheet would be obtained and compared. Besides, the influence of the vacancy defect position is evaluated. For this purpose, the defect is considered at the center, left, and right hand sides of the nanosheet. It is seen that the electric current changes by changing the position of the vacancy defect, which is related to the electronic structures of BN nanosheets. In addition, the transmission and conductance for BN nanosheets with vacancy continuously change by changing the bias voltage. The obtained results can benefit the design and implementation of BN nanosheets in nanoelectronic systems and devices.

Abstract
Microplastics are pollutants with uncertain behaviors; they have mysterious impacts on marine environments. In the present study, surface water samples from 25 different locations in the Inner Gulf of Thailand were collected to assess the distribution of microplastic contamination. Microplastics were visually counted and identified by Fourier-transform infrared microscopy. The results revealed that the average total abundance of microplastics (125–5000 µm) was 9.97 pieces/L (1.55 ng/L). Microplastics sized 125–300 µm were most abundant at all the sampling sites, accounting for 68% of the total microplastics. Fiber (35%) and fragment (34%) were the predominant microplastic shapes in the surface water. Polyethylene, polypropylene, and poly(ethylene propylene) accounted for the most prevalent polymer types. The present findings revealed that the Inner Gulf of Thailand is moderately polluted by microplastics of different sizes, shapes, and types, which may pose a potential risk to coastal ecosystems.

Abstract
Introduction The prevalence of psychosocial distress is up to 45% among cancer patients. It is crucial to identify and treat distress. The aim of the study is to report on the prevalence of distress among cancer patients, analyze the variable causes of distress and to study the effect of the disease stage using the Distress Thermometer. Methods We studied distress among 3 groups, each consisting of 100 patients: those initially diagnosed, patients undergoing treatment, and patients who were referred to the palliative team. Different variables such as time of screening, sex, age, nationality, and tumor type were analyzed.Results There was an overall distress incidence of 62% (level ≥ 4) and out of that 17% of the patients had severe distress (level >7). Similarly, there was 75% of distress among patients who were referred to palliative care, compared to 56% of patients at initial diagnosis and 54% for those undergoing cancer treatments. In addition, women (69%) had more distress (53%). Expatriates had high distress, compared to Qataris (64.3% versus 51%). Breast (69%) and lung (70%) cancer patients had the highest level of distress. Physical causes of distress were the most common followed by emotional causes.Conclusion There is a substantially higher overall incidence of distress among cancer patients in Qatar. Distress should be assessed in patients at cancer diagnosis and at the time of disease progression. Screening alone isn’t enough, the different causes of distress should be identified and addressed by the appropriate interventions.

Abstract
Today, designing low-power single-bit SRAM structures with the ability to operate regularly at low supply voltages and with high immunity against standard radiation particles impact is challenging for designers. In the present article, a novel design of a low-power radiation-hardened single-ended SRAM bit-cell (UPRHSE) based on gate-diffusion input (GDI) method using gate-all-around carbon nano-tube (CNT) MOSFETs (GAA CNT-MOSFETs) along with dual-chirality/multiple-diameter technique for CNTs with an asymmetric virtual ground gating and built-in read-assist schemes with inherent single-node event upset (SEU) preventive and self-correction capabilities and a high degree of robustness against multiple-node event upsets (MEUs) in the presence of more consumption area storage has been proposed. In order to investigate single/double upset injection circuit model using the structure of the T-connected pseudo resistors (TPRs) has been proposed. Also, based on the analytical-compact model, an equation for calculating the data-retention voltage (VDR) metric for the suggested bit-cell structure and an algorithm for facile estimate of VDR for other bit-cell architectures is presented. The results of extensive Monte-Carlo (MC) simulations to evaluate the proposed bit-cell indicate larger noise margins, acceptable yield, less sensitivity to process, voltage and temperature (PVT) variations, higher critical charge and consequence more robustness to soft errors with high reliability of data storage in standby mode in the presence of voltage conditions lower than the nominal power supply, and better results in other comprehensive figure of merits (FoMs) criteria compared to nanotechnology-based state-of-the-art radiation-hardened (rad-hard) bit-cell circuits with the same number of transistors in the 16 nm technology node. So, the proposed UPRHSE design can be a reasonable choice for applications that demands high stability, impact resistance to radiation particles and extremely low power in a radiation abundant environment with limited-energy sources. Finally, in order to use the suggested UPRHSE bit-cell in a real application with secure data transfer approach, the suggested structure is employed for storing. The results show the better performance of UPRHSE in terms of other comprehensive FoMs based on PSNR and MSSIM metric to evaluate the appropriate accuracy in pixel-by-pixel image compared to other well-known counterpart designs.

Abstract
Doxorubicin (DOX) is a well-known chemotherapeutic drug for most malgnencies including breast cancer and leukemia whilst the usage of DOX is limited owing to its cardiotoxicity. The present study analyzed the effects of crocin on doxorubicin’s cardiotoxic efect in rat myocardium and searched their mechanistic interaction in the pathogenesis of DOX-induced myocardial toxicity. Forty rats were divided into four groups; (a) control (received normal saline as a dose of 1 ml/kg by ip for 15 days), (b) Crocin (received crocin as a dose of 40 mg/kg/24h by ip for 15 days), (c) DOX (received DOX as a dose of 2 mg/kg/48h by ip in six injection, cumulative dose 12 mg/kg), and (d) DOX + Crocin (received DOX as a dose of 2 mg/kg/48h by ip in six injection and crocin as a dose of 40 mg/kg/24h ip for 15 days). According to the present study, DOX administration caused significant increases in lipid indices (triglyseride, low-dencity lipoproteins and very low-dencity lipoproteins) as well as cardiac markers (Creatine kinase-muscle/brain and Cardiac Troponin I). Morever, DOX caused significant increases in oxidative stress parameters (malondialdehyde and total oxidant status) as well as decreases in antioxidant defense systems (glutathione, superoxide dismutase, catalase and total antioxidant status). The present study also demonstrated that co-administration of crocin with DOX significantly ameliorated the lipid profile and biochemical parameters in rats receiving DOX. The results were supported by histopathological and immunohistochemical evaluations. Taken together, our results reveal that crocin might be a cardioprotective agent in DOX treated patients for cancer.

Abstract
Bromuconazole is a triazole pesticide used to protect vegetables and fruits against diverse fungi pathologies. However, its utilization may be accompanied by diverse tissues injuries. For this, we tried to examine bromuconazole effects in liver and kidney tissues by the evaluation of biochemical and histopathological modifications also by genotoxic and oxidative stress analysis. Adult male Wistar rats were divided into four groups, each consisting of 6 animals. The control group received daily a corn oil (vehicle) orally. Three oral Bromuconazole doses were tested (1, 5 and 10 % of LD50) daily for 28 days. Bromuconazole increased the plasma activities of transaminases (AST, ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), creatinine and uric acid levels. histopathological check showed that Bromuconazole caused organs failure. This study make known that Bromuconazole caused conspicuous DNA damage either in hepatic and kidney tissues, with a significant increase in malondialdehyde and protein carbonyl levels followed by the increase in the enzymatic activity of catalase and superoxide dismutase in a dose dependent manner. Glutathione-S-transferase (GST) and peroxidase (GPx) activities were also recorded. Our results highlight that bromuconazole exposure induced genotoxic damage and organs failure that may be caused by the disturbances of oxidative stress statue in liver and kidney tissues.

Published: May 2021

Abstract
Background: Patient-based analysis of social media is a growing research field with the aim of delivering precision medicine but it requires accurate classification of posts relating to patients’ experiences. We motivate the need for this type of classification as a pre-processing step for further analysis of socialmedia data in the context of related work in this area. In this paper we present experiments for a three-way document classification by patient voice, professional voice or other. We present results for a Convolutional Neural Network classifier trained on English data from two different data sources (Reddit and Twitter) and two domains (cardiovascular and skin diseases). Results: We found that document classification by patient voice, professional voice or other can be done consistently manually (0.92 accuracy). Annotators agreedroughly equally for each domain (cardiovascular and skin) but they agreed more when annotating Reddit posts compared to Twitter posts. Best classification performance was obtained when training two separate classifiers for each data source, one for Reddit and one for Twitter posts, when evaluating on in-source test data for both test sets combined with an overall accuracy of 0.95 (and macro-average F1 of 0.92) and an F1-score of 0.95 for patient voice only.Conclusion: The main conclusion resulting from this work is that using more data for training a classifier does not necessarily result in best possible performance. In the context of classifying social media posts by patient and professional voice, we showed that it is best to train separate models per data source (Reddit andTwitter) instead of a model using the combined training data from both sources. We also found that it is preferable to train separate models per domain (cardiovascular and skin) while showing that the difference to the combined model is only minor (0.01 accuracy). Our highest overall F1-score (0.95) obtained for classifying posts as patient voice is a very good starting point for further analysis of social media data reflecting the experience of patients.

Abstract
The multi-drug resistance is one of the most actual medical and ecological problem. Stenotrophomonas, Xanthomonas, Pseudomonas are common, drug resistant and highly adaptive phytopathogenic and opportunistic pathogenic microbes. Tartaric acid is natural safe antimicrobial agent. In current paper it is discussed the synthesis and antimicrobial activity of tartaric acid new derivatives, which were investigated in our laboratory. There were obtained benzyl, cyclohexyl and phenyl substituted imides as well as complex amine salts of tartaric acid. Their antimicrobial activity was tested on native soil Pseudomonas, Xanthomonas and Stenotrophomonas different strains from The National Microbe Collection of Scientific and Production Center (SPC) “Armbiotechnology” National Academy of Sciences of Republic of Armenia (NAS RA).As a result of cultivation on appropriate compound containing media, as well as genetical analyses of tested microbes and docking analyses, it was found out that tartaric acid carbocyclic and aromatic imides and complex salts are effective as non-selective growth inhibitors. Complex salts of tartaric acid are biodegradable by some soil strains of P. chlororaphis, etc. Thus, all the elaborated compounds can be recommended for further study of their activity as an effective alternative against the multi-drug resistant microorganisms.

Published: May 2021

Abstract
Background
Informal caregivers play a fundamental role in the care of hematological cancer patients, but less is known about how secondary caregivers are involved. We assessed the presence or absence of a secondary caregiver, the types of caregiving activities performed by primary and secondary caregivers and examined whether the presence of a secondary caregiver was associated with primary caregiver characteristics and wellbeing over time.
Methods
A case series of hematological cancer patient-caregiver dyads (n = 171) were recruited from oncology clinics in Virginia and Pennsylvania and followed for 2 years. Multi-level models were developed to examine the associations between presence of a secondary caregiver and the primary caregivers’ well-being.
Results
Most (64.9%) primary caregivers reported having secondary caregivers. Multilevel models showed primary caregivers without help had higher baseline mental and physical health, but experienced deteriorating physical health overtime, compared to supported primary caregivers. Supported primary caregivers reported improvements in mental health over time that was associated with improvements in physical health.
Conclusions
Primary caregivers in good physical and mental health at the beginning of their caregiving journey but who have the least assistance from others may be at greatest risk for detrimental physical health effects long term. Attention to the arrangement of caregiving roles (i.e., who provides what care) overtime is needed to ensure that caregivers remain healthy and well supported.
