Incidence of Coagulase Negative Staphylococci in Various Clinical Samples in Tertiary Care Hospital, Nepal

Objectives: To determine incidence of coagulase negative Staphylococci (CoNS) in various clinical samples along with the study of their multi drug resistance, methicillin resistance and biofilm formation. Methods: A hospital based cross-sectional study was conducted which included 1875 clinical samples. The isolation and identification of isolates was done following standard microbiological protocol. The CoNS were identified phenotypically on the basis of gram staining, slide and tube coagulase test and through various carbohydrates fermentation tests. Antibiotic susceptibility test was done by Kirby Bauer disk diffusion method (Clinical and Laboratory Standards Institute 2020) whereas biofilm production was determined by Tissue Culture Plate (TCP) technique. Results: A total of 32 CoNS, comprising of 6 species were identified. S. epidermidis (43.8%) was the most common species isolated followed by S. saprophyticus (28.1%), S. haemolyticus (15.6%), S. hominis (6.3%), S. lugdunensis (3.1%) and S. cohini (3.1%). Further, 27 (84.4%) of CoNS were found to be multidrug resistant, 22 (68.8%) methicillin resistant and 8 (25%) showed positive D- test. Strong biofilm production was detected in 9 (28.1%) isolates of CoNS, 10 (31.3%) were moderate biofilm producers and 13 (40.6%) non/weak biofilm producers. The equal distribution, 9 (33.3%) each of strong, moderate and non/weak biofilm producers were found among 27 isolates of MDR. Among 22 methicillin resistant isolates, 9 (40.9%), 7 (31.8%) and 6 (27.3%) were strong, moderate and non/ weak biofilm producers respectively. All isolates were sensitive against Linezolid followed by Cotrimoxazole. Conclusion: The increasing multi drug resistance among CoNS should be rationally approached with the use of proper antibiotics while treating the patients.
The effects of waste derived fertilisers and composts on crop production

The waste from olive oil production is a valuable source of nutrients that has the potential, when used well, to be a useful organic amendment to aid crop growth. It does have some drawbacks with potential phytotoxicity due to being likely to have a high amount of phenols present and a high conductivity. The waste from olive oil production used in these trials was composted with different animal manures to produce a number of products with different characteristics. In some of the trials a replacement form of organic amendment in the form of chicken manure was used instead. In addition to these amendments, some of the trials included biochar as an additional organic amendment to see if the properties of the biochar had any effect on plant development and yield. The trials discussed in this thesis take place over a 3 year period on 3 different crops: winter wheat, oilseed rape and strawberries. The wheat was grown at both field and pot scale in the trials. The field scale trials with oilseed rape and winter wheat showed no significant differences between yields when comparing a mineral fertiliser to a substitute chicken manure fertiliser. In the first harvest year the oilseed rape showed significantly higher yields on the plots that received biochar as an amendment, however this result was not replicated by the winter wheat in that or the subsequent harvest year. When the olive mill waste compost was used as a substrate replacement for strawberries, the strawberry crop showed no significant patterns or changes in development due to the amendment applied in the first year. In the subsequent when used again as a growth media and more graduated inclusion amounts (% v/v) the OMW caused plant mortality in plants receiving more than 20% inclusion of compost. The compost used in this year had a high conductivity to which the high plant mortality was attributed. The plants that received more than15% OMW compost also produced significantly less marketable fruit, and the fruits produced were more poorly pollinated. In the same year, the OMW was applied to wheat at pot trial scale, but used as a fertiliser and applied at the same nitrogen loading rate as the mineral nitrogen applied. In this trial there was no plant mortality of the wheat, and no discernible difference in the plant development. These trials have shown that compost of olive mill waste and animal manures can be used as an alternative to traditional mineral fertilisers on both arable and horticultural crops in the UK and as a soilless media replacement, however it is important to consider the characteristics of the OMW before applying it.

Design, construction and performance analysis of dynamic torque transducer

Most of the dynamic torque measurement devices present are not easy to afford and accurate for higher shaft speed, at the same time, especially in the case of Micro-hydropower stations where dynamic torque fluctuates and requires constant monitoring. To fulfill the lack of standard devices, this project concentrated on fabricating non-contact torque transducer devices using easily accessible materials. The project primarily focuses on developing electronics and mechanical systems required to measure dynamic torque. The hollow Aluminum shaft is taken as a torque transducer specimen with a coupling facility. A strain gauge is attached with the specimen shaft in the Wheatstone bridge arrangement such that the strain gauge produces an electrical signal while the shaft experiences strain. Arduino NANO as an I/O device, HX711 ADC module as a signal amplifier, HC05 as a Bluetooth module for wirelessly measured data communication. For calibration, torque is applied to the specimen by coupling it with motor-generator dynamic torque measurement apparatus (DL 10055ETM) which is manufactured by DE LORENZO. Linear regression is used to predict the value of applied torque. The experimental data obtained using the proposed torque transducer prototype has made it clear that it is possible to measure and analyze real-time digital data of dynamic torque produced on specimen shaft rotating at high speed, wirelessly, using locally available resources.
Biopolymeric Nanogel as a Drug Delivery System for Doxorubicin—Improved Drug Stability and Enhanced Antineoplastic Activity in Skin Cancer Cells

In this study, doxorubicin was loaded in a chitosan–albumin nanogel with the aim of improving its stability and exploring the potential of the system in the treatment of skin cancer. Infrared spectroscopy and X-ray diffraction confirmed the encapsulation of the drug. Transmission electron microscopy revealed the spherical shape of the nanogel particles. The drug-loaded nanogel was characterized with a small diameter of 29 nm, narrow polydispersity (0.223) and positive zeta potential (+34 mV). The exposure of encapsulated doxorubicin to light (including UV irradiation and daylight) did not provoke any degradation, whereas the nonencapsulated drug was significantly degraded. In vitro studies on keratinocytes (HaCaT) and epidermoid squamous skin carcinoma cells (A-431) disclosed that the encapsulated doxorubicin was more cytotoxic on both cell lines than the pure drug was. More importantly, the cytotoxic concentration of encapsulated doxorubicin in carcinoma cells was approximately two times lower than that in keratinocytes, indicating that it would not affect them. Thus, the loading of doxorubicin into the developed chitosan–albumin nanogel definitely stabilized the drug against photodegradation and increased its antineoplastic effect on the skin cancer cell line.
Albuminuria, Forgotten No More: Underlining the Emerging Role in CardioRenal Crosstalk

Kidneys have an amazing ability to adapt to adverse situations, both acute and chronic. In the presence of injury, the kidney is able to activate mechanisms such as autoregulation or glomerular hyperfiltration to maintain the glomerular filtration rate (GFR). While these adaptive mechanisms can occur in physiological situations such as pregnancy or high protein intake, they can also occur as an early manifestation of diseases such as diabetes mellitus or as an adaptive response to nephron loss. Although over-activation of these mechanisms can lead to intraglomerular hypertension and albuminuria, other associated mechanisms related to the activation of inflammasome pathways, including endothelial and tubular damage, and the hemodynamic effects of increased activity of the renin–angiotensin–aldosterone system, among others, are recognized pathways for the development of albuminuria. While the role of albuminuria in the progression of chronic kidney disease (CKD) is well known, there is increasing evidence of its negative association with cardiovascular events. For example, the presence of albuminuria is associated with an increased likelihood of developing heart failure (HF), even in patients with normal GFR, and the role of albuminuria in atherosclerosis has recently been described. Albuminuria is associated with adverse outcomes such as mortality and HF hospitalization. On the other hand, it is increasingly known that the systemic effects of congestion are mainly preceded by increased central venous pressure and transmitted retrogradely to organs such as the liver or kidney. With regard to the latter, a new entity called congestive nephropathy is emerging, in which increased renal venous pressure can lead to albuminuria. Fortunately, the presence of albuminuria is modifiable and new treatments are now available to reverse this common risk factor in the cardiorenal interaction.
Organic carbon inputs, common ions and degassing: rethinking mixing dissolution in coastal eogenetic carbonate aquifers

Caves deliver freshwater from coastal carbonate landscapes to estuaries but how these caves form and grow remains poorly understood. Models suggest fresh and salt water mixing drives dissolution in eogenetic limestone, but have rarely been validated through sampling of mixing waters. Here we assess controls on carbonate mineral saturation states using new and legacy geochemical data that were collected in vertical profiles through three cenotes and one borehole in the Yucatan Peninsula. Results suggest saturation states are primarily controlled by carbon fluxes rather than mixing. Undersaturation predicted by mixing models that rely on idealized end members is diminished or eliminated when end members are collected from above and below actual mixing zones. Undersaturation due to mixing is limited by CO2 degassing from fresh water in karst windows, which results in calcite supersaturation. With respect to saline groundwater, controls on capacity for mixing dissolution were more varied. Oxidation of organic carbon increased pCO2 of saline groundwater in caves (pCO2 = 10–2.06 to 10–0.96 atm) relative to matrix porosity (10–2.39 atm) and local seawater (10–3.12 atm). The impact of increased pCO2 on saturation state, however, depended on the geochemical composition of the saline water and the magnitude of organic carbon oxidation. Carbonate undersaturation due to mixing was limited where gypsum dissolution (Cenote Angelita) or sulfate reduction (Cenote Calica) increased concentrations of common ions (Ca2+ or HCO3−, respectively). Maximum undersaturation was found to occur in mixtures including saline water that had ion concentrations and ratios similar to seawater, but with moderately elevated pCO2 (Cenote Eden). Undersaturation, however, was dominated by the initial undersaturation of the saline end member, mixing was irrelevant. Our results add to a growing body of literature that suggests oxidation of organic carbon, and not mixing dissolution, is the dominant control on cave formation and enlargement in coastal eogenetic karst aquifers.

Cross-Cultural Differences in Online Communication Patterns

Purpose: The main objective of this study was to explore the cross-cultural differences in online communication patterns. Methodology: The study adopted a desktop research methodology. Desk research refers to secondary data or that which can be collected without fieldwork. Desk research is basically involved in collecting data from existing resources hence it is often considered a low cost technique as compared to field research, as the main cost is involved in executive’s time, telephone charges and directories. Thus, the study relied on already published studies, reports and statistics. This secondary data was easily accessed through the online journals and library. Findings: The findings revealed that there exists a contextual and methodological gap relating to the cross-cultural differences in online communication patterns. Preliminary empirical review revealed the importance of cultural sensitivity in the digital age. It has emphasized the need for individuals and organizations to adapt their online communication practices to accommodate the rich tapestry of cultures that populate the digital landscape. By doing so, we can foster more meaningful and harmonious cross-cultural online interactions, ultimately contributing to a more interconnected and culturally aware global society. Unique Contribution to Theory, Practice and Policy: The Cultural Dimensions theory, Communication Accommodation theory and Media Richness theory may be used to anchor future studies on online communication patterns. The study suggested the several recommendations to enhance cross-cultural online communication. These include promoting cultural sensitivity in online communities, customizing user experiences to align with cultural preferences, emphasizing digital literacy and cross-cultural training, and investing in ongoing research and data-driven strategies. Implementing these recommendations can foster respectful and inclusive online interactions in a rapidly evolving digital landscape, benefiting individuals, organizations, and online platforms alike.
Effects of Daily Mean Temperature on Daily Hospital Admissions for Coronary Artery Disease: A Retrospective Study

Purpose Temperature changes unfavorably impact on cardiovascular disease. However, the association between temperature changes and coronary artery disease (CAD) is not well documented. This study aimed to explore the association between daily mean temperature and daily CAD hospital admissions on the southeast coast of China (Fuzhou City). Methods A total of 1883 CAD patients who underwent percutaneous coronary intervention between 2017 and 2019 were obtained. The severity of CAD was evaluated by the Gensini score. Distributed lag non-linear model (DLNM) combined with a quasi-Poisson regression model was used to examine the delayed effect between daily mean temperature and daily CAD hospital admissions. Stratified analyses were performed by Gensini score and severity of lesions. The relative risk (RR) with a 95% confidence interval (CI) was used to assess the relationship. Results Extreme cold (8°C) (RR=0.49, 95% CI: 0.25–0.99) and moderate cold (10°C) (RR=0.56, 95% CI: 0.31–0.99) daily mean temperature with a lag of 0–20 days were correlated with lower risk of daily CAD hospital admissions. Moderate heat (30°C) (RR=1.80, 95% CI: 1.01–3.20) and extreme heat (32°C) (RR=2.02, 95% CI: 1.01–4.04) daily mean temperature with a lag of 0–20 days related to a higher risk of daily CAD hospital admissions. Similar results were observed for daily mean temperature with a lag of 0–25 days. Stratified analysis showed the lagged effect of daily mean temperature (lag 0, 0–5, 0–15, 0–20, and 0–25 days) on the daily CAD hospital admissions was observed only in patients with a Gensini score ≤39 (tertile 1). Conclusion Cold temperatures may have a protective effect on daily CAD hospital admissions in the Fuzhou area, whereas hot temperatures can have an adverse effect.
Carbon Fluxes from Different Pools in a Mined Area under Reclamation in Minas Gerais State, Brazil

Despite the benefits of grass cultivation and organic fertilization in mining areas undergoing reclamation, these practices may be associated to CO2 emissions and soil organic matter (SOM) losses by priming effect. In the present study, we evaluated the changes on SOM pools and C–CO2 emissions in a bauxite‐mined area under reclamation fertilized with poultry litter (PL) (0, 10, 20, and 40 Mg ha−1) and cultivated with Brachiaria brizantha. Increases of about 3·5 times in the soil labile C were observed 1 year after experiment establishment. High C–CO2 fluxes and a significant positive priming effect were observed in the presence of B. brizantha, increasing native C mineralization by nearly 4·9 times. Nevertheless, no net soil C loss was detected, probably because of the C inputs derived from B. brizantha, which offset these losses. In fact, the grass increased total organic C by 45% when fertilized with 40 Mg PL ha−1. The data obtained suggest that the cultivation of B. brizantha fertilized with PL can be a promising option for rapid recovery in SOM in areas under reclamation.

Implementation of the Contextual Teaching and Learning Model in the Al-Liqo Al-Usbuiyyah Program: Case Study in Higher Education in Indonesia

University students generally study Arabic with the aim of understanding Islamic study sources such as the Al-Qur'an and hadith, specifically as a means of verbal and written communication. However, from the results of initial observations, researchers found that the interest and motivation of students at one of the State Islamic Religious Universities (PTKIN) in Indonesia in mastering Arabic still needed to be higher. In an effort to overcome this problem, the PTKIN management created a program called al-liqo al-usbuiyyah using the Contextual Teaching and Learning (CTL) learning model. Therefore, this research aims to explore the efforts made by PTKIN management to foster student interest and motivation in mastering Arabic. A qualitative descriptive research method with a case study approach was used in this research. The results of this research show that the al-liqo al-usbuiyyah program using the Contextual Teaching and Learning (CTL) learning model runs well and is proven to be able to increase student interest and motivation in mastering Arabic. This research also describes several obstacles experienced in implementing this program, such as limited time, busy and varied lecture schedules, students' psychological conditions, and heterogeneous initial understanding of members.
Effect of tropical Indian Ocean thermal condition during preceding winter on summer high temperature anomalies over the southern Yangtze River valley

The present study investigates signals of summer high temperature anomalies over the southern Yangtze River valley (SYRV) region. The results show that summer high temperature anomalies over the SYRV region are associated with preceding winter sea surface temperature (SST) and surface air temperature (SAT) anomalies over the tropical Indian Ocean (TIO), particularly the tropical northwestern (5°–15°N, 55°–75°E) and southwestern (15°S–0°N, 40°–55°E) Indian Ocean regions. Coupled with SST, positive SAT anomalies over the TIO region may persist from preceding winter to summer, leading to more summer precipitation over the northwestern India and Arabian Sea (IAS) region. More summer precipitation (increased condensational heating) over the IAS region can regulate the strength and location of the western Pacific subtropical high and the South Asian high and result in their vertical superposition over the SYRV region. As such, a deep and stable high‐pressure anomaly forms over the SYRV region and results in high temperature anomalies. In this process, anomalous precipitation over the IAS region may to some degree act as a ‘bridge’ in providing a delayed impact of the preceding winter TIO SAT on summer SAT over the SYRV region. The effect of the preceding winter TIO SAT on summer SYRV SAT becomes weaker after removing the variability of IAS precipitation.
Une nouvelle métrique avec référence complète d'évaluation de la qualité d'images couleur

The human have always seen the world in color. Recently, there has been rapid and enormous transition from grayscale images to color ones. The advance in the field of image processing raises a great need for estimating the image quality especially in the area of compression (JPEG \ JPEG2000). This area is experiencing a growing interest growing among the approaches used. We distinguish those based on the subjective test and those using objective measures automatic. But, it is accepted by the scientific community, that only subjective approaches give actual results although they are expensive. On objective measures of the most known and used are: the mean square error (MSE), Peak Signal to Noise Ratio (PSNR) and those based on the characteristics of the Human Visual System (HSV) as ESSIM (Edge Based Structural Similarity). One of the common and major limitations of these objective measures is that they evaluate the quality of grayscale images only and don't make use of image color information. However, color is a powerful descriptor that can influence the decision of the human being. In this paper, we propose a new full reference metric for assessing the distortion of the color in the compressed images inspired by the human visual system (HVS). The experimental study shows the comparative performance of the proposed metric to the existing ones.
