Thermal Performance of Nano Refrigerants: A Short Review

The efforts to promote energy-efficient and environmentally friendly nano-based refrigerants are now being favoured. To this effect, in this paper, the new trend, prospects, and investigations of nano-based refrigerants in refrigeration systems are reviewed. It was found that various thermal characteristics have been reported as favourable regarding nano refrigerants. These include a reduction in the power consumption, increase in the coefficient of performance (COPr), improved tribological pressure drop property of nano-lubricant, and increase in the thermal conductivity of the hybrid-refrigerant. The discussions here thus suggest that nano-particles are highly favoured to be included in a typical refrigeration system.
4.0. Prevalence of ESBL genes in Klebsiella pneumoniae from individuals with community-acquired urinary tract infection in rural communities of Enugu State,

https://doi.org/10.30574/gscbps.2022. 19.3. 0249 Abstract Background: The emergence and spread of extended-spectrum beta-lactamase (ESBL) producing Enterobacteriaceae is now a major challenge in treating urinary tract infections. This study was conducted to determine the Prevalence of ESBL genes in Klebsiella pneumoniae and the influence of these genes on the antimicrobial susceptibility patterns of the isolates, obtained from community acquired urinary tract infection in Enugu state rural communities. Method: A total of 735 clean catch mid-stream urine samples were collected from February, 2021 to June, 2021. The urine samples were cultured and Klebsiella pneumoniae were identified morphologically, biochemically, and then typed down, using PCR, Gel electrophoresis, and Sanger Sequencing by Genewiz. Antibiotic susceptibility testing was done by modified Kirby-Bauer disc diffusion method and interpretation was done following Clinical and Laboratory Standard Institute (CLSI) guidelines. ESBL screening was done by the phenotypic method, using the standard disk diffusion method, whereas the phenotypic confirmation of ESBL producers was done by the double-disk synergy method, and interpreted according to CLSI guidelines. Multiplex PCR was used to detect the genes for SHV and CTX-M while conventional linear PCR was done for TEM and blas GES type ESBL genes. Results: A total of 77 isolates were identified as Klebsiella pneumoniae , and the prevalence of positive ESBL in them were 10(12.9%). Of the 77 isolates that were tested for antibiogram, 29 isolates were multidrug-resistance (MDR). Out of the MDR isolates, 10 were ESBL positive, whereas 19 were not. Of this 29 MDR isolates, 6 were extensively-drug resistant (XDR). Of the 6 XDR isolates, 3 do not possess ESBL enzymes, whereas 3 of them do. Age range of 31-40 contributed the highest prevalence of ESBL genes (60%), whereas age range of 10-20, 21-30, and 51-70 did not produce any ESBL gene. bla TEM gene was the most prevalent ESBL resistant genes with a prevalence of 10 (100%), followed by SHV 9(90%), whereas bla GES gene and bla CTX-M have the least prevalence of 4 (40%) each. Conclusion: Higher prevalence of MDR, XDR, and ESBL-producing Klebsiella pneumoniae were observed, thus the need for public health intervention for effective prevention and control of antimicrobial resistance, and proper treatment of 70 volts for 90 min and visualized/ illuminated under ultraviolet transilluminator. A 100 bp DNA ladder (Norgen Biotek Corp., Canada) was used as DNA molecular weight marker.
The effect of exchange rate volatility in economic growth: a literature review.

The globalization process brings so many changes to economic factors all over the world. According to the economists, exchange rate fluctuation is one of the indicators of a country's economy that is directly affected by economic integration or international trade. The study of exchange rates fluctuation, especially in fragile economies like Albania, has a large interest to see why this countries has fluctuated sharply in recent decades, and the most important is to find the factors that have led to these movements. Generally, a devaluation of the domestic currency facilitates the growth of exports of domestic goods and services by making our goods cheaper in foreign markets and reduces the demand for imported goods in the country. While the strengthening of the domestic currency certainly has the opposite effect, as it makes exports more expensive, import products become more competitive and this will also affect the deepening of the country's trade deficit. Albania is a country with a small and open economy, and in this case the exchange rate of the local currency plays an important role in the level of prices, in the level of productivity, in the volume of foreign assets held in the country as well as in attracting investments. According to researchers, exchange rate stability helps the country's financial stability in the short term and the long term. The study of exchange rate behavior is the object of our study, in terms of the impact that exchange rate fluctuations have on the economy especially in Foreign Direct Investment, international trade, and macroeconomic factors. This paper is presented an extensive literature review to analyze the impact of exchange rate fluctuations in the economy, from the perspective of different authors.
ISSUES AND CHALLENGES: AN EXPLORATORY CASE STUDY ON MOSQUES INSTITUTION IN FEDERAL TERRITORY

This study contributes to the literature pertaining to the understanding of the issues and challenges related to practices of accounting in mosque institution. It highlights on the elements of financial accountability i.e. accounting practices and financial reporting in four selected mosques in the State Islamic Religious Councils of Federal Territory. It provides an insightful meaning of the issues and challenges on how accounting is practice in these mosques. Over a three-month period, a series of unstructured interviews with selected key mosques leaders, imam, treasurers and/or accounts clerks have been conducted. Several documents of the mosques financial records such as financial statement, Friday collection statements and other accounting records were studied. In addition, an observation has been done in one of the mosques to observe the event of counting Friday collection. It is observed that, accounting is regarded as pivotal to exhibit accountability of the mosques in pursuing their missionary activities. Concurrently, financial accountability serves as a medium to portray accountability. Accounting is loosely practiced in the mosque institution. The variations of practising accounting in these organisations portray the dynamism of accounting in their organisation.

Replies to the NTIA Challenge RFC

• Incentives and Infrastructure. Small teams not traditional telecom equipment manufacturers need to be incentivized to participate in the challenge and bring to the table non-traditional solutions that will advance the US wireless ecosystem. To that end, they will need (i) access to development resources/funding; (ii) access to testing platforms with carrier-grade scale and equipment. Moreover, the challenge needs to be structured to provide incentives to develop high-quality, carrier-grade, reliable software, that is ready or almost ready for production. Therefore, the DoD could address this and foster participation to the challenge by allowing the U.S. wireless ecosystem to expand to non-traditional actors and thrive by (i) allowing small entities to tap into a common, large-scale testing infrastructure with open interfaces for the software development of this challenge; (ii) promoting testing-driven development for high-quality, reliable software, and (iii) granting development funding to the participants of the challenge.
Motivational factors for online grocery shopping

This paper aims to understand the motivational factors including social influences, facilitating conditions, hedonic motivations, perceived risk and perceived trust which influence the consumers’ intention to purchase grocery online. From the literature review, this paper found that many studies have investigated numerous factors for purchase intention, especially, in the cases which fashion and trends are involved. However, few studies have focused on the factors that affect consumers’ intention to online grocery shopping. Influences from family members, friends and media have been considered as the key factors affecting purchase intention of consumers to shop grocery online. Particularly, when the consumers without experience in online grocery shopping. Moreover, consumers might need self-efficacy to perform shopping online. On the other hand, consumers’ purchase intention is usually based on the quality and quantity of the product information. Hedonic motivated consumers will find more information about online shopping as they feel overwhelmed and happy in what they do. In fact, some consumers hesitate to buy online because of risk factor; therefore, it relies on trust. The review hopes to trigger future empirical studies to identify what factors could influence consumers’ intention in buying groceries online.
Aqueous Stability Studies of Polyethylene Glycol and Oleic Acid-Based Anionic Surfactants for Application in Enhanced Oil Recovery through Dynamic Light Scattering

The present study investigates the aqueous stability of polyethylene glycol and oleic acidbased anionic surfactants through the dynamic light scattering (DLS) and zeta potential methods, for application in enhanced oil recovery (EOR). Polyethylene glycol dioleate sulfonate (PDOS) surfactant solutions were prepared in concentrations of 0.05, 0.1, 0.3, 0.5, and 1 wt% in deionized water. Aqueous stability of PDOS was assessed by measuring the droplet size over five days, using nano particle analyzer HORIBA SZ-100 at 25 o C. Results show that good aqueous stability of PDOS was achieved at concentrations of 0.1 to 1 wt%, but with the droplet size becoming unstable at the lowest concentration of 0.05 wt%. The polydispersity indices were classified into polydisperse distribution type recorded as 0.3 to 0.5 at concentrations of 0.05 and 0.1 wt% and 0.2 at concentrations of 0.3 to 1 wt%. The critical micelle concentration (CMC) of PDOS was 0.3% and the interfacial tension of PDOS surfactant above the CMC was around 10 -3 dyn/cm. The zeta potential of PDOS surfactant without the addition of salt in concentrations of 0.05, 0.1, 0.3, 0.5, and 1 wt% was highly stable up to -96.8, -90.5, -89.6, 82.3, and -64.4 mV, respectively. With the addition of salt they were moderately stable at a concentration of 1 wt%. The conductivity increased with increasing concentration. The zeta potential of PDOS with the addition of salt was moderately stable in a concentration of 1%. Although PDOS with concentration of 0.05% showed a high value of zeta potential with the addition of salt, there is no guarantee that the PDOS surfactant solution will be stable for five days.
A No-Biopsy Approach for the Diagnosis of Celiac Disease in Adults: Can It Be Real?

Background and objective Pediatric guidelines on the diagnosis of celiac disease (CD) have reported that the positivity of anti-endomysium antibodies in the presence of anti-transglutaminase antibodies (TGA) 10 times higher than normal is sufficient for the diagnosis. In this study, we aimed to evaluate whether this diagnostic process for children can also be applied to adult patients. Materials and methods We retrospectively examined patients aged >18 years who were diagnosed with CD. The results of serological tests and endoscopic biopsy were evaluated. Patients with more than one month of duration between celiac serology and endoscopy, those diagnosed with CD before admission, those on a gluten-free diet, and those with selective IgA deficiency were excluded from the study. Results A total of 269 patients were included in the study. TGA value was significantly higher in patients with villous atrophy (p<0.001) and positively correlated with mucosal damage (r=0.60, p<0.01). Considering the cut-off value of 100 U/mL (>10 ULN) for the TGA antibodies, in line with the criteria regulated by the European Society for Paediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) for the diagnosis of CD, the sensitivity was 71.64%, the specificity was 100%, and the positive predictive value (PPV) was 100%. When the cut-off value was taken as 29.42 U/mL, the sensitivity was 100% and the specificity was 99.5%. For a TGA cut-off value of 52.7 U/mL (5.27 ULN), which determines the presence of partial or complete villous atrophy in the evaluation made considering mucosal damage, the sensitivity was 90%, the specificity was 100%, and the PPV was 100%. Conclusion Based on our findings, TGA titers were highly effective in demonstrating CD-related mucosal damage. This study endorses a biopsy-free strategy in adult patients in line with the ESPGHAN criteria. Local validation of test-specific thresholds will ensure that this approach has a significant impact on adult patients.
The high diversity and phylogenetic signal of antipredator mechanisms of the horned frog species of Proceratophrys Miranda-Ribeiro, 1920 (Amphibia: Anura: Odontophrynidae)

Phylogenetic signals indicate the phenotypic similarity of antipredator mechanisms among related species. Herein, we assessed the antipredator mechanisms of the horned frog Proceratophrys laticeps, compiled a database including closely phylogenetically-related species, and evaluated their phylogenetic signals. Our dataset comprises 80 records for 13 species of Proceratophrys, totalizing 11 antipredator mechanisms and 15 variations of these mechanisms. Six antipredator mechanisms show high similarity in the trees’ roots within Proceratophrys (e.g., aggression, aposematism, camouflage, distress call, immobility, and interrupt calling). Our observations show the first records of antipredator mechanisms for P. laticeps, and the first report of interrupt calling for Proceratophrys genus, contributing to the knowledge on the behavioural ecology of Proceratophrys species, addressing new insights for ecological trait evolution by multiple ancestral states of amphibians.
Geomorfologia Brasileira: Análise bibliométrica da produção de alto impacto no quinquênio entre 2016-2020

O trabalho analisa a produção geomorfológica brasileira em quatro periódicos de alto fator de impacto no período entre 2016 e 2020, um nacional e três internacionais. Objetivou traçar a evolução dessa produção, bem como verificar as redes de cooperação nacionais e internacionais geradas através das publicações. Os resultados demonstraram um aumento na produção brasileira nacional e, principalmente, internacional, permitindo maior participação na produção científica global em relação ao quinquênio anterior. Além do quantitativo geral de publicações, houve um reposicionamento das unidades federativas quanto à produção internacional. São Paulo, Paraná, Rio de Janeiro e Minas Gerais continuam sendo importantes, mas merecem destaque os estados do Pará e do Rio Grande do Sul que duplicaram sua produção. Comparado aos quinquênios anteriores, foi constatado ainda um aumento na cooperação entre pesquisadores de instituições diferentes. As redes de cooperação nacional e internacional mostraram que as instituições mais relevantes para a produção são justamente aquelas com maior número de colaborações e diversidade de colaborações. Porém, apesar do desenvolvimento no âmbito internacional, o percentual da contribuição do Brasil na produção global total ainda é pequeno. Sendo assim, o desenvolvimento de mais cooperações parece ser o caminho mais promissor para mudar este cenário.
Effect of phytase supplementation on performance, bone densitometry and carcass yield in broilers chicks - doi: 10.4025/actascianimsci.v33i3.10702

An experiment was conducted to evaluate the performance, bone densitometry and carcass yield of broilers chicks, using different levels of phytase enzyme. Nine hundred and sixty male one-day-old broiler chicks were used. The birds were distributed in a completely randomized experimental design, involving five treatments and six replications of 32 chicks each. The treatments consisted of a control diet for each phase, and four other diets were formulated adding growing levels of the phytase enzyme (250, 500, 750 and 1,000 FTU of phytase kg -1 feed). When adding the phytase enzyme, the nutritional matrix was valued to guarantee the same nutritional levels as the control diet. In general, the addition of phytase enzyme determined a linear decrease on the performance of the birds. However, the performance obtained with the level of 250 FTU phytase kg -1 feed were no different from the control treatment. The best bone density results were observed in the control treatment with no phytase, and the highest leg and thigh yield were obtained at the level of 514 FTU phytase kg -1 .
Design & Analysis of the Mechanical System for a Spacial 4-DOF Series-parallel Hybrid Lower Limb Rehabilitation Robot

： It’s a hot potato in social problem that there are large number patients with disabilities and fewer doctors. accident or other disease are the leading cause of disability. In order to reduce the disability rate, improve the quality of life, meet the needs of patients, a new type lower limb rehabilitation robot is presented. The robot is made up of attachment bracket, a seat and two 4 DOF mechanical legs which is based on series-parallel hybrid mechanics (UPS-UPU-U)&RR. It has three training models as standing, lying and sitting. It can meet the needs of patients at different stages of rehabilitation training. The kinematics and DOF of the robot are analyzed by constructing vector constrain equation and screw theory. The analysis result is verified by the software ADAMS. This result lays the foundation for making prototype in the future.
Unobtrusive touch‐free interaction on mobile devices in dirty working environments

In this work, we propose a new mode of interaction using hand gestures captured by the back camera of a mobile device. Using a simple intuitive two‐finger picking gesture, the user can perform mouse click and drag‐and‐drop operations from the back of the device, which provides an unobstructed touch‐free interaction. This method allows users to operate on a tablet and maintain full awareness of the display, which is especially suitable for certain working environments, such as the machine shop, garage, kitchen, gym, or construction site, where people's hands may be dirty, wet, or in gloves. The speed, accuracy, and error rate of this interaction have been evaluated and compared with the typical touch interaction in an empirical study. The results show that, although this method is not, in general, as efficient and accurate as direct touch, participants still consider it an effective and intuitive method of interacting with mobile devices in environments where direct touch is impractical.
'Cambridge Moralica' - Towards an Ethical Framework for Social Media Analytics

En route to the unravelling of today’s multiplicity of societal challenges, making sense of social data has become a crucial endeavour in Information Systems (IS) research. In this context, Social Media Analytics (SMA) has evolved to a promising field of data-driven approaches, guiding researchers in the process of collecting, analysing, and visualising social media data. However, the handling of such sensitive data requires careful ethical considerations to protect data subjects, online communities, and researchers. Hitherto, the field lacks consensus on how to safeguard ethical conduct throughout the research process. To address this shortcoming, this study proposes an extended version of a SMA framework by incorporating ethical reflection phases as an addition to methodical steps. Following a design science approach, existing ethics guidelines and expert interviews with SMA researchers and ethicists serve as the basis for redesigning the framework. It was eventually assessed through multiple rounds of evaluation in the form of focus group discussions and questionnaires with ethics board members and SMA experts. The extended framework, encompassing a total of five iterative ethical reflection phases, provides simplified ethical guidance for SMA researchers and facilitates the ethical self-examination of research projects involving social media data.
Transfacet Oblique Lateral Lumbar Interbody Fusion: Technical Description and Early Results

Introduction The oblique lateral lumbar interbody fusion (OLLIF) is a relatively new method of lumbar interbody fusion (LIF) that utilizes a trans-Kambin approach to the disc space. The OLLIF can be performed from T12-S1 in the majority of cases but is occasionally obstructed at the L5-S1 level by osteophytes, an overgrown facet joint and/or prominent sacral ala. Transfacet OLLIF (TF-OLLIF) is a novel method for LIF in which the disc space is accessed by drilling through hypertrophic facets with an OLLIF approach. We provide a proof-of-concept report on the TF-OLLIF surgical technique and report the clinical and perioperative outcomes for the first 29 patients who underwent this procedure. Methods This is a retrospective single surgeon cohort study of 29 patients with lumbar spinal stenosis (LSS) who underwent TF-OLLIF procedures between 8/2018 and 1/2021. The primary outcome was a change in the Oswestry Disability Index (ODI) one year after surgery. Secondary outcomes were surgery time, blood loss, hospital stay, and complications. The TF-OLLIF was performed using the approach and instrumentation of OLLIF. When osseous hypertrophy is reached during the approach, an 8 mm drill is used to drill through the obstructing bone with continuous neuromonitoring. Discectomy and interbody placement are performed with subsequent posterior pedicle screw fixation. Results ODI improved from 49% pre-op to 31% at one-year follow-up. Estimated blood loss ranged from 97.6±93.3 ml for one level TF-OLLIF to 146.2±60.3 ml for a 3+ level TF-OLLIF. Operative time ranged from 57.4±19.5 minutes for a one-level TF-OLLIF to 102.9±27.8 minutes for a 3+ level TF-OLLIF. The average length of hospital stay (LOS) was 0.4±0.8 days for one-level TF-OLLIF and 1.6±1.9 days for 3+ level TF-OLLIF. Complications included five cases of nerve root irritation immediately postoperatively, with three of these patients still reporting mild L5 distribution numbness at the last follow-up, which was not clinically limiting. Conclusion The first 29 cases of TF-OLLIF demonstrated that it is a safe method of interbody fusion that yields good clinical results. This is an important development for practitioners of OLLIF as it enables interbody placement with OLLIF instruments and approach even for challenging L5-S1 levels without compromising surgical outcomes.
