Sustainable Water Use Practices: Understanding and Awareness of Masters Level Students

Present water consumption in the UK is unsustainable, with increasing societal and environmental pressures driving water stress. Personal use of water is a significant contributor to water demand and considering the number of universities and students in the UK the water use practices therein cannot be ignored. Therefore, this paper aims to deepen the theme of water consumption in the United Kingdom from the point of view of use practices for students. The originality in this research lies in better understanding whether UK Masters level students have a basic awareness of personal water consumption and water pricing and whether they have a preferred approach to reducing their water consumption—through a behavioral change, or through adoption of technologies. Through use of a questionnaire approach applied to five cohorts (2017 to 2021) of Masters level students, the level of understanding and awareness towards their own domestic water use both now and in the future was demonstrated. Key findings suggest that Masters students underestimated their water use by 76% compared to the average UK national range and that there was an overall preference to adopt water saving technologies rather than changing user behavior (40% vs. 27%). The study concludes that it is important to approach water conservation from an SPT perspective in order to achieve meaningful change in water use practices. Qualitative and quantitative research is analyzed in light of theoretical models (i.e., Social Practice and Attitude Behavior Framework ABC) in order to make recommendations for greater societal prominence for this issue through media and education.

Measuring the Level of Job Satisfaction of University Academics: a Cross-Sectional Study from Bangladesh

This study inspects the job satisfaction level of academic staff at Rajshahi University, Bangladesh. Important factors that have an impact on job satisfaction levels are work itself, pay, promotion opportunities, supervision, and relationship with co-workers. A sample of 120 teachers is selected by convenient sampling from the nine faculties at Rajshahi University. With the support of SPSS, factor analysis, Co-relation, and regression tests are conducted to generate results. Through the statistical analysis, it is found that teachers are more satisfied with work itself, relationship with co-workers, and they are less satisfied with the pay structure, promotion opportunities, and supervision. Thus findings recommend that boosting the work facilities and ensuring the smooth and cooperative relationship with co-workers could be helpful tools in motivating faculty members and subsequently get attached with their work.
Seasonal Variations of Densities of Biomphalaria pfeifferi, the Intermediate Host of Schistosoma mansoni Parasite at the North of Senegal

Schistosomiasis is becoming more persistent because of the widespread distribution of intermediate host snails in several regions of Africa, including Senegal. The intermediate snail host of the human intestinal schistosome is Biomphalaria pfeifferi and is permanently present in northern Senegal because of the presence of the abundant freshwater habitat throughout the year. Here, we observed the seasonal variation in B. pfeifferi abundance in the Saint-louis region at the North of Senegal in West Africa. We performed snail and environmental parameter sampling across two different seasons described for Senegal: a dry season that runs roughly from mid-October to mid-June and a rainy season that spans approximately from late June to early October. We also split the dry season into two categories representing periods of time when water temperatures were either decreasing (dry1) or increasing (dry2). We used regression analyses to model snail density across the seasons and investigated which environmental variables influenced snail abundance. Results suggested that snails were more abundant and peaked during the rainy season, which lowest abundances during the dry season when temperatures were declining. The above seasonal variations of snail density were positively linked to the environmental drivers including periphyton (food resource for snails), aquatic vegetation abundance, water temperature and dissolved oxygen and negatively to both pH and water conductivity. Our findings may be useful for snail control efforts by targeting specific periods and/or site conditions when snail abundances are greatest.
The Effects of Subthreshold Autistic Traits On Time Perception: The Regulation of Interpersonal Information Association

Background People with high subthreshold autistic traits usually show structural impairments like those with autism spectrum disorder, but with less social and cognitive impairments. The effect of autistic traits on time perception and the role of interpersonal information on this effect remains unexplored. Methods This study used a temporal bisection task between 400–1600 ms to compare the time perception of individuals with higher and lower autistic traits, and to explore the influence of interpersonal information on their time perception by establishing associations between interpersonal information and geometric figures. A total of 32 participants with high autistic traits and 31 participants with low autistic traits took part in the study. Results In the absence of identity information, people with high autistic traits tended to judge short durations as longer, and their Weber ratio was higher than those with low autistic traits, suggesting that their overestimation of short duration is due to decreased temporal sensitivity and increased internal clock frequency. With the addition of interpersonal information, individuals with high and low autistic traits had faster responses to self in the identity-figure association, and the subjective bisection point was shorter. However, it took longer for individuals with high autistic traits to build the self-association, and there was no difference in the proportion of long response and Weber ratio between individuals with high and low autistic traits when identity was involved. Conclusion These results suggest that individuals with high autistic traits have a higher central tendency, and this change is related to the decline of perceptual sensitivity. Actively guiding attention to interpersonal information can improve the time perception sensitivity of individuals with high autistic traits.
Frequency of allogenic blood transfusion in patients with gastrointestinal cancer: a cross-sectional study in Peru

Background Gastrointestinal cancer demands a high frequency of transfusions, and the high availability of blood products. We aimed to determine the frequency of blood transfusions and the most used blood products according to the type of gastrointestinal cancer. Methods A cross-sectional study was conducted in a Peruvian Type I Hemotherapy and Blood Bank Service of a Private Oncological Clinic during 2016–2018. We included patients with gastrointestinal cancer using the International Code of Diseases. The donations were made in compliance with the requirements of the Programa Nacional de Hemoterapía y Banco de Sangre and in accordance with the Standardised Operational Procedure of the clinic. Results We analysed 3,022 patients, of which 163 (5.4%) had gastrointestinal cancer (67.1 ± 12 years). The 80 (49.1%) men did not show significant differences with the 83 (50.9%) women (p = 0.178). The most frequent neoplasia was the colon (41.7%) and pancreas (37.4%). Three hundred and four blood products were transfused (average 1.8 ± 2.5 units (range: 1–30 units/patient)), of which 81.3% (247 units) were red blood cells concentrated, 8.6% (26 units) were fresh-frozen-plasma (FFP) and 6.6% (20 units) were cryoprecipitate. The type of cancer that most blood products demanded was colon neoplasia (41.8%), followed by pancreatic cancer (26.3%) and liver cancer (10.9%). We determined that ~55% of patients were O Rh(D)+ and in five patients we were poly-transfused. Conclusion Our findings suggested that patients with gastrointestinal cancer require large numbers of transfusions of blood cell concentrate and FFP. Also, we showed that cancer of the colon, pancreas and liver demanded more than 75% of blood products.
Ultrawideband Beam Steering at mm-Wave Frequency With Planar Dielectric Phase Transformers

In this article, a new method to design an ultrawideband beam-steering antenna system is presented. The system is completely passive and suitable for millimeter-wave applications, including some in defense, where both discrete beam steering and continuous beam steering in two dimensions (elevation and azimuth) are required at a reasonably fast speed. The beam-steering capability is achieved using a pair of distinct low-profile and planar phase transformers (PPTs) placed in the near-field region of a fixed-beam radiating source. The antenna system demonstrates a steering and impedance-matching bandwidth of 28.6%, from 30 to 40 GHz. A prototype of the new antenna system, including a pair of thin PPTs and a completely automated mechanical system to rotate each of the PPTs around the antenna axis, has been fabricated and tested. The pair of rotating PPTs, equivalent to a pair of 3-D dielectric PTs (DPTs), introduces a precalculated phase gradient to the input near field from the fixed-beam antenna and creates an output near field that will radiate toward a selected direction, which can be varied within a large conical region with a maximum apex angle of 108°. The system exhibits the predicted and measured peak gains of 21.5 and 21.7 dBi, respectively, and the measured gain variation over 2-D beam steering is less than 2.2 dB. This beam-steering method obviates the need for expensive phase shifters and distribution networks, which are also lossy at mm-wave frequencies. The measured results validate the predicted wideband matching and steering performance of the system with a close agreement.
Targeted Intervention of eIF4A1 Promotes EMT and Metastasis of Pancreatic Cancer Cells through c-MYC/miR-9 Signaling

Background: Due to the lack of effective interference options, early metastasis remains a major cause of pancreatic ductal adenocarcinoma (PDAC) recurrence and mortality. However, the molecular mechanism of early metastasis is largely unknown. We characterize the function of eukaryotic translation initiation factors (eIFs) in Pancreatic cancer cell epithelial mesenchymal-transition (EMT) and metastasis, to investigate whether it is effective to inhibit EMT and metastasis by joint interference of eIFs and downstream c-MYC. Methods: We used the data of The Cancer Genome Atlas (TCGA) and Genome Tissue Expression (GTEx) to analyze the expression level of eIF4A1 in PDAC tissues, and further validated in a microarray containing 53 PDAC samples. Expression regulation and pharmacological inhibition of eIF4A1/c-MYC was performed to determine their role in migration, invasion, and metastasis in pancreatic cancer cells in vitro and in vivo.Results: Elevated expression of eIF4A1 was positively correlated with lymph node infiltration, tumor size, and indicated a poor prognosis. eIF4A1 decreased E-cadherin expression through c-MYC/miR-9 axis. Ablation of eIF4A1 and c-MYC decreased the EMT and metastasis capabilities of pancreatic cancer cells. Upregulation of eIF4A1 could attenuate the inhibition of EMT and metastasis induced by c-MYC downregulation. Single-use of eIF4A1 inhibitor Rocaglamide (RocA) or c-MYC inhibitor Mycro3 and joint intervention all significantly the EMT level of pancreatic cancer cells in vitro. However, the efficiency and safety of RocA single-use were not inferior to joint use in vivo. Conclusion: The results demonstrated that overexpression of eIF4A1 downregulated E-cadherin through c-MYC/miR-9 axis, which promoted EMT and metastasis of pancreatic cancer cells. Despite the potential loop between eIF4A1 and c-MYC existing, RocA single strategy was a promising therapy for the inhibition of eIF4A1 induced PDAC metastasis.
Hyperspectral Image Denoising Using Factor Group Sparsity-Regularized Nonconvex Low-Rank Approximation

Hyperspectral image (HSI) mixed noise removal is a fundamental problem and an important preprocessing step in remote sensing fields. The low-rank approximation-based methods have been verified effective to encode the global spectral correlation for HSI denoising. However, due to the large scale and complexity of real HSI, previous low-rank HSI denoising techniques encounter several problems, including coarse rank approximation (such as nuclear norm), the high computational cost of singular value decomposition (SVD) (such as Schatten <inline-formula> <tex-math notation="LaTeX">$p$ </tex-math></inline-formula>-norm), and adaptive rank selection (such as low-rank factorization). In this article, two novel factor group sparsity-regularized nonconvex low-rank approximation (FGSLR) methods are introduced for HSI denoising, which can simultaneously overcome the mentioned issues of previous works. The FGSLR methods capture the spectral correlation via low-rank factorization, meanwhile utilizing factor group sparsity regularization to further enhance the low-rank property. It is SVD-free and robust to rank selection. Moreover, FGSLR is equivalent to Schatten <inline-formula> <tex-math notation="LaTeX">$p$ </tex-math></inline-formula>-norm approximation (<xref ref-type="theorem" rid="theorem1">Theorem 1</xref>), and thus FGSLR is tighter than the nuclear norm in terms of rank approximation. To preserve the spatial information of HSI in the denoising process, the total variation regularization is also incorporated into the proposed FGSLR models. Specifically, the proximal alternating minimization is designed to solve the proposed FGSLR models. Experimental results have demonstrated that the proposed FGSLR methods significantly outperform existing low-rank approximation-based HSI denoising methods.
Integrated Coupler-Antenna Design for Multibeam Dual-Polarized Patch-Array Rectenna

The multibeam antenna can facilitate effective harvesting of RF energy with low power densities, different polarizations, and different incident directions. The use of coupler-based beamforming circuit in the array antenna is a common implementation method. The inevitable coupling between antenna elements is usually an obstacle to compactness due to the separate design of antenna and circuit. In this article, a scheme is proposed to integrate two coupled patches and two hybrid couplers. It exploits the unfavorable coupling in conventional designs and can reduce both the spacing between antenna elements and the redundant circuit of hybrid coupler. A compact four-beam rectenna is then presented with high gains and dual polarizations in enhanced spatial coverage. The complex <inline-formula> <tex-math notation="LaTeX">$J$ </tex-math></inline-formula> inverter, instead of commonly used real one, is introduced to characterize the coupling and reflect its effect on excitation of antennas. With an optimized four-branch rectifier circuit corresponding to the four beams, the rectenna demonstrates a maximum dc power of 54.1–<inline-formula> <tex-math notation="LaTeX">$66.3~\mu \text{W}$ </tex-math></inline-formula>, a maximum RF-to-dc efficiency of 44.3%–52.3%, and a minimum dc power of 24.5–<inline-formula> <tex-math notation="LaTeX">$28.7~\mu \text{W}$ </tex-math></inline-formula> in an azimuth angle range of 90° when the incident RF power is with different linear polarizations and a density of <inline-formula> <tex-math notation="LaTeX">$1~\mu \text{W}$ </tex-math></inline-formula>/cm<sup>2</sup>.
Implementation of Enterprise Resource Planning (ERP) in Bangladesh -Opportunities and Challenges

An enterprise resource planning (ERP) project is a sizable enterprise application either in the business and engineering perspective. It creates huge alterations and frequently entails calling into question several traditional roles within the business, for which individuals are rarely well ready. It frequently involves the execution of numerous new approaches and their integration with existing programs and frequently reflects one of the bigger IT jobs -- one of the highly crucial ones in many businesses, cooperation between industry and IT extends into international cooperation between many small business units and many entities of their IT division. The achievement of this undertaking will count on the caliber of the cooperation. Before beginning such a difficult endeavor, certain conditions have to be ensured. The business has to see to adulthood in ERP and also the management and technical capacities of their IT division and the capability of the business and IT to work together. Without these requirements, companies wouldn't have the ability to lead and get different stages of an ERP project. This preparation could require a few educational and communication efforts which can be essential for success. This study has been undertaken to address the viability of installing ERP in any enterprise and its benefits and challenges in Bangladesh. ERPs are highly technical issues with numerous benefits. It requires a lot of preconditions to be installed. By reviewing the literature and going through several recent research, a concept is tried to be developed here in this study. Idea about current status of ERP practices in Bangladesh has been generated from various circulars and reports produced by the companies. The study found that productivity and profits are increased by implementing ERP in the local enterprises but a lot of challenges are to be addressed. The infrastructure of IT and power supply should be ensured to gain optimum advantages. The employees should be well trained to run the system successfully.
Algorithms for Predicting the Probability of Azoospermia from Follicle Stimulating Hormone: Design and Multi-Institutional External Validation

Purpose To predict the probability of azoospermia without a semen analysis in men presenting with infertility by developing an azoospermia prediction model. Materials and Methods Two predictive algorithms were generated, one with follicle stimulating hormone (FSH) as the only input and another logistic regression (LR) model with additional clinical inputs of age, luteinizing hormone, total testosterone, and bilateral testis volume. Men presenting between 01/2016 and 03/2020 with semen analyses, testicular ochiodemetry, and serum gonadotropin measurements collected within 120 days were included. An azoospermia prediction model was developed with multi-institutional two-fold external validation from tertiary urologic infertility clinics in Chicago, Miami, and Milan. Results Total 3,497 participants were included (n=Miami 946, Milan 1,955, Chicago 596). Incidence of azoospermia in Miami, Milan, and Chicago was 13.8%, 23.8%, and 32.0%, respectively. Predictive algorithms were generated with Miami data. On Milan external validation, the LR and quadratic FSH models both demonstrated good discrimination with areas under the receiver-operating-characteristic (ROC) curve (AUC) of 0.79 and 0.78, respectively. Data from Chicago performed with AUCs of 0.71 for the FSH only model and 0.72 for LR. Correlation between the quadratic FSH model and LR model was 0.95 with Milan and 0.92 with Chicago data. Conclusions We present and validate algorithms to predict the probability of azoospermia. The ability to predict the probability of azoospermia without a semen analysis is useful when there are logistical hurdles in obtaining a semen analysis or for reevaluation prior to surgical sperm extraction.

This study examined the effect of some climatic variables and their role in growing citrus fruits in northern Saudi Arabia, which showed that low temperatures accompanied by calm winds and high relative humidity as well as creeping air masses are among the most important factors that contribute to the worsening of frost. This study also dealt with hourly frost waves - a case study - based on the study of climatic data of the study area stations for one day of frost waves that occurred in the study area for the year 2008.
Scenarios for oil palm expansion in degraded and deforested lands in the Brazilian Amazon to meet biodiesel demand

Palm oil production for biodiesel in Brazil is characterized by its high productivity in some environmental conditions, under the Sustainable Palm Oil Production Program. The program seeks to avoid deforestation for oil palm cultivation, recover degraded lands, and focus on social inclusion and family farming. This paper assesses the possible socio-environmental impacts of the expansion of palm oil until 2030, focusing on land-use change and impacts. Land-use data came from the TerraClass initiative for the analysis of degraded forests using geoprocessing. We produced two oil expansion scenarios. The first one reflects current trends in palm oil production expansion and deforestation in Pará State (S1). The second one considers the exclusive use of deforested/degraded land for oil palm crops (S2). The results demonstrate that degraded/deforested land in the current palm oil-producing municipalities is only sufficient for the projected level of expansion for 2020, requiring a stronger public policy to recover degraded areas for oil palm cultivation with social inclusion of family farming.
