Authors: Mandal Adhirath , Cho HaengMuk , Chauhan Bhupendra Singh
Published: February 2023

The transport industry has been an important sector, and controls a major portion in the country’s economy. The transport sector are mainly dependent on fossil fuels. The amount of fossil fuels is limited and if we deplete the fossil fuels the future will be doubtful. The use of fossil fuels generate a lot of hazardous pollution such as CO, unburnt HC, NOx and emission of greenhouse gases. Recently the environmental problems are increasing day by day because of the emissions. Therefore there is requirement to shift to cleaner fuels or alternate fuels. As the emissions are rising the demand for alternate fuels are increasing day by day. It is estimated that in the US, transportation sector consumes about 62% of the oil imported. Because of the rise in demand many researches have been made in the field of alternate fuels. Fuels with high oxygen content have the possibility to be used as an alternate fuel. Biodiesel is a substitute of diesel fuel, compound of ester (higher oxygen content). Another alternate to conventional fuels if the electric vehicles. The hybrid electric vehicle are mainly of two types on the basis of powertrain, firstly parallel and secondly series. The paper is a review work on different types of fuels used and throws light on the upper hand and downsides of the different fuels used. It also exhibits the effect of these fuels on the environment.

Published: February 2023

Now a days everyone is using mobile phones. Mobile phones play an important role in communication. While using mobile phones, people face the problem of noise signals. These noise signals are affecting the quality of speech signals. These noise signals maybe produced from the materials or sources such as echoes, crowded places, etc. For example, when we speak over the mobile phone or in any crowded place, the external noise adds up like the noise of the subway, train, car, etc. In real time to remove external noise is a very crucial task. A lot of research has been done in cancelling the background noise reduction. Acoustic noise is a type of noise which can produce unwanted sound and it can be reduced by selecting a higher switching frequency (at the cost of higher inverter losses). So a new technique was introduced called passive noise cancellation that supresses higher frequency acoustic noise. In order to supress the lower frequency, the passive techniques require materials that is too bulky and heavy. For these materials, an alternative method is required known as active noise cancellation. This technique does not come without its change as it is used to actively cancel the noise of the world around you to make your audio come clearer. Active noise cancellation separates noise signal and the speech signal is chosen. In order to use active noise cancellation, we use zero frequency filter technique for the cancellation of noisy speech signals. It is used for detecting the regions of glottal activity and in estimating the strength of excitation n each glottal cycle. The main advantage of active noise cancellation is to cancel the random sounds due to repetition in the waveform. ANC is used in the reduction by using a power source. It is best suited for low frequencies. VLSI architecture for zero frequency filter can be used as a voice processor in mobile applications. The existing system has produced a time delay of 220ps. In this paper, we are reducing the time delay into 120ps by using tanner tool software.

Tea is a gift of China to the world. It is a popular beverage consumed by almost every person globally, after water. Green tea has not gone under oxidation process and found beneficial for human consumption because of its medicinal properties and presence of some nutrients and minerals required by human beings for a healthy life. Molecular component of green tea (Polyphenols, catechins, flavonoids and minerals) makes it suitable in ailments and some microbial infections. Oral cavity has the second largest and diverse microbiota after gut, as numerous microorganisms such as bacteria, fungi and viruses exist in the mouth. Streptococcus mutans is facultative, anaerobic oral bacteria mainly responsible for tooth decay was selected for the present study because dental plaque and caries are common infections found in population. For experimental purpose 30 healthy individuals were randomly selected from the college campus (MIET, Meerut). Saliva of each individual was taken twice i.e. before and after green tea consumption. For identification and confirmation of S. mutans, biochemical tests have been done. The effect of green tea was observed by the growth and count of S. mutans on common (nutrient agar media) and special media (Mitis Salivary agar media). Plates were showing less count after green tea consumption as compared to the plates before consumption of green tea. On the basis of the results, it can be concluded that Green tea is the natural preventive and curative agents and is good to consume once in a day to reduce the count of Streptococcus mutans in mouth to maintain oral health.

Published: February 2023

Smart City is a booming international concept. Smart cities concept reiterates to what we have already been doing so far as Planners and Architects. However, the smart cities concept today, especially in India, in its ideological sense of the term, has more to do with the efficiency and accuracy of our planning systems by the use of resources to get the most benefit, with minimum cost and damage. The conceptualization of Smart City, therefore, varies from city to city and country to country, depending on the level of development, willingness to change and reform, resources and aspirations of the city residents. The paper aims at understanding the approach for “Smart city “in context to the city Ajmer. The vision statement for Ajmer has been evolved after extensive citizen consultations, self-assessment of the city, and analysis based on the previously prepared city reports/ documents. The city's vision has been validated with the help of various stakeholders along with the mapping of desires of the citizens of Ajmer. The vision is based upon five core themes that have been derived from this process with an aim to develop Ajmer as a global, religious and heritage tourism destination with high quality living and sustainable smart citizen services.

Pathways Into Couchsurfing From Child Safety Involvement
Authors: Hail-Jares Katie , Vichta-Ohlsen Rhianon
Published: February 2023

Couchsurfing, or temporarily staying with friends, extended family, acquaintances, or strangers, is a growing form of homelessness within Australia, and particularly concentrated among youth. System involvement with child welfare and its link to youth homelessness has previously been well-established, but not within the context of couchsurfing. In interviews with 19 young people with both couchsurfing and a history of system-involvement, we identify and describe six different pathways into couchsurfing. These pathways extended from the beginning to the end of their child safety involvement, and demonstrate how fear of reprisal for reporting, fear of out-of-home-care, and lack of transition planning pushed-or-pulled young people into couchsurfing. These findings indicate the link between couchsurfing and child safety involvement began very early in the investigative process, suggesting multidisciplinary service teams that include housing support should be involved in initial contact. We also echo the recommendations of other researchers to prioritise Housing First programming and risk assessment for evaluating young people’s living spaces.

Authors: Abdillah M. Rifqy Nurfauzan , Suwardi
Published: February 2023

Tax treaties or P3B have been recognized for their important role to attract Foreign Direct Investment (FDI), giving legal certainty, providing tax relief, creating non-discrimination protection, and providing dispute mechanism in international tax. Nevertheless, the existing research that has been available so far yielded varied results with none of those examining the perspective of investors. This research aims to evaluate the state of the treaty as well as identify reasons to negotiate from the perspective of the investors. The data used are primary or first-hand data which is generated from the list of questions. This paper uses exploratory and explanatory methods to define the factors to renegotiate based on the survey and examine the effect of the variables determined from the survey results. The object of this research is the investors and potential investors that are represented by their tax consultant whose they possess the necessary knowledge to answer the questions. This study shows that their perception of tax treaties has a significant effect on their participation. However, a more thorough examination is necessary to explain how tax treaty policy should be formulated.

Is Fluoroquinolone Exposure after Primary Tendon Repair Associated with Higher Rates of Reoperations? A Matched Cohort Study
Authors: Waters Timothy L , Ross Bailey J , Wilder J. Heath , Cole Matthew W , Collins Lacee K , Sherman William F
Published: February 2023

Background

The association between tendon damage and fluoroquinolone (FQ) antibiotics has been well documented. However, there is limited data evaluating the impact of postoperative FQ use on outcomes of primary tendon repairs. The purpose of this study was to compare rates of reoperation for patients with FQ exposure after primary tendon repair versus controls.

Methods

A retrospective cohort study was conducted using the PearlDiver database. All patients who underwent primary repair of distal biceps ruptures, Achilles tendon ruptures, and rotator cuff tears were identified. For each tendon, patients who were prescribed FQs within 90 days postoperatively were propensity score matched at a 1:3 ratio with controls without postoperative FQ prescriptions across age, sex, and several comorbidities. Rates of reoperation were compared at two years postoperatively with multivariable logistic regression.

Results

A total of 124,322 patients who underwent primary tendon procedures were identified, including 3,982 (3.2%) patients with FQ prescriptions within 90 days postoperatively: 448 with distal biceps repair, 2,538 with rotator cuff repair, and 996 with Achilles tendon repair. These cohorts were matched with 1,344, 7,614, and 2,988 controls, respectively. Patients with postoperative FQ prescriptions exhibited significantly higher rates of revision surgery after primary repair of distal biceps ruptures (3.6% vs. 1.7%; OR 2.13; 95% CI, 1.09—4.04), rotator cuff tears (7.1% vs. 4.1%; OR 1.77; 95% CI, 1.48—2.15), and Achilles tendon ruptures (3.8% vs. 1.8%; OR 2.15; 95% CI, 1.40—3.27).

Conclusion

Patients with FQ prescriptions within 90 days after primary tendon repair demonstrated significantly higher rates of reoperations for distal biceps, rotator cuff, and Achilles tendon repair at two years postoperatively. To achieve optimal outcomes and avoid complications in patients following primary tendon repair procedures, physicians should consider prescribing alternative non-FQ antibiotics and counsel patients on the risk of reoperation associated with postoperative FQ use.
Multiple rare organisms causing ventriculoperitoneal shunt infection and brain abscess
Authors: Shihadeh Omar M. , Amin Hayel , Hammadi Firas
Published: February 2023

Ventriculoperitoneal shunts (VPS) are inserted to treat issues with CSF flow dynamics, such as obstructions causing CSF build up which raises the intracranial pressure. A major complication of this procedure is VPS infections. Vast majority of VPS infections are monomicrobial and may occur in the first two years of insertion due to contiguous or hematogenous spread. Here, we report a rare case of polymicrobial VPS infection with 5 pathogens. One of these organisms (Citrobacter werkmanii) has been reported as a cause of meningitis for the first time in this report. The other organism (Enterococcus casseliflavus) has been reported as a cause only one other time. Hence, we recommend considering these newly emerging organisms when dealing with meningitis.

Porém, constantes mudanças sociais ocorridas no século XXI e o reconhecimento do protagonismo feminino são fatores que têm levado as empresas ao reposicionamento em relação ao consumo de bebidas por mulheres. Isso tem exigido mudanças nas empresas, não somente em questão de produtos, mas especialmente na comunicação de marketing.

Implicações para a gestão ou sociais: A proposta deste caso é promover uma melhor compreensão sobre os problemas relacionados à comunicação de marketing ligada a temas sensíveis, de modo a permitir que os gestores desenvolvam estratégias de comunicação mais assertivas em relação ao contexto social atual.

Children presenting with high blood sugar in our clinics are often diagnosed with Type 1 diabetes considering the age of the patient. This case will highlight the need for proper diagnosis in the children to provide them with suitable treatment as per their diagnosis. We report a case of an 8-year-old boy who presented with complaints of weight loss of approximately 2 kg in a span of two months. His height was 134.9 cm and weight was 47 kg with a BMI of 26. His family history of diabetes was positive. To our surprise the patient did not have a simple case of type 1 diabetes as expected, the patient responded well to the diet and lifestyle modification in the beginning, and after a few months, he was started on anti-diabetic treatment as his blood sugar showed a spike. The final diagnosis for this patient was considered as latent autoimmune diabetes of young/ children as the patient’s GAD 65 was highly positive and C-peptide levels were normal. The correct diagnosis of diabetes type in children can help them to prevent the unnecessary psychological burden of multiple injection therapy from a young age and provide them with good quality of life and preserve their beta cells with minimal insulin therapy. Keywords: Latent Autoimmune Diabetes; Auto-antibodies; Diabetes Mellitus; C-peptide

Highways perform a seminal role in the economic development for any country. The road network is a crucial infrastructure that needs to be developed and kept in a function able condition; so that, its benefits can be achieved. For ages, pavements were kept but not administered. The expertise of the pavement engineer determined the choice of Maintenance and Repair (MR) methods regardless of the expense and quality of the life cycle as opposed to other pavement segments in the map of the roads` network. Nowadays, in the light of economic environment, since the pavement infrastructure has worn out, a more organized and disciplined way to specify MR needs and priorities seems a must. To keep the pavements well, the factors affecting pavement performance need to be identified. Examples of such factors are climate, drainage, material properties, construction quality and traffic loads. Due to exposure to traffic and environmental factors distresses show up with time throughout the service life of the pavement. Thus, pavement performance is negatively affected and if not treated at the right time, the service life will be shorter along with inferior ride quality. In order to evaluate pavement condition and thus its performance, a reliable pavement condition index is needed. This index is based upon pavement condition surveys which can be conducted either manual (visual inspection) or automated (by a van). If the quality of the pavement is assessed and the distresses are identified, there are currently several indices available for evaluating pavement performance. This paper presents a comparative study between the pavement condition indices to determine the most suitable method for implementation in roads.

Education has long been considered a key predictor of job performance. However, the relevance of educational qualifications to the job performance of academic administrative staff in a university in the Western Cape province of South Africa is not understood by the administrative managers of the university. This study aimed to determine the relationship between educational qualifications and job performance among university staff in academic administrative positions and to make recommendations to improve the current situation. It utilized the Individual Work Performance Questionnaire (IWPQ), which is a 47-item instrument developed to measure work performance at the individual level. After defining job performance into four-dimensional behavior patterns (Contextual Performance Behavior, Adaptive Performance Behavior, Task Performance Behavior, and Counterproductive Work Behavior), the results indicated no significant correlations between job performance and the level of qualifications (as measured against the National Qualifications Framework) held by employees. Spearman’s Rho tests were then used to determine the relationship between respondents' National Qualifications Framework level of qualifications and their performance ratings. A moderately significant positive correlation (p=0.056) between the National Qualifications Framework level and job performance ratings that ‘exceed the requirements’ of the job was observed. The research helps to determine the preferred educational levels for academic administrative positions of varying complexity and provides the University with additional guidelines to recruit staff who are most likely to impact organizational objectives positively.

Nowadays, modern agriculture has benefited from Precision Agriculture (PA) through incorporation of technological advances like the use of GIS (Geographic Information Systems), RS (Remote Sensing), GPS (Global Positioning System) and advanced information processing. Based on the GIS, RS and GPS, a study was conducted to develop a cropland map using GIS and remotely sensed unsupervised algorithm for suitability analysis of paddy harvester. The research was carried out at four selected locations such as Kulbaria-Baratia, Mundopasha, Charwapda, and Holdibaria villages of Dumuria, Wazirpur, Subarnachar and Kalapara upazilas of Khulna, Barishal, Noakhali Patuakhali districts, respectively in the southern Bangladesh. The satellite images for GIS mapping were captured at vegetation stage of Boro-2018 and Aman-2018 during March-April and October-November. Technical performances of reaper and combine harvester were used to determine the required number harvester based on the estimated cultivated area found through GIS maps. The calculated required number of a) reaper, b) mini combine and c) medium combine to cover the estimated paddy area are a) 17 and 16, 1 and 5, 38 and 127, 6 and 21, b) 35 and 32, 3 and 10, 76 and 254, 13 and, 42 and c) 10 and 9, 1 and 3, 21 and 72, 4, and 12 during Boro and Aman seasons at Kulbaria-Baratia, Mundopasha, Charwabda and Holdibaria of Dumuria, Wazirpur, Subarnachar and Kalapara upazilas, respectively. The estimated results revealed that GIS tools and remote sensing are helping in simplification and visualization by incorporating data sets which can supports decision making for the implementation of paddy harvesting technologies in order to ensure the proper agricultural mechanization. Based on the accuracy assessment, GIS tool is found very useful to assess area to be harvested mechanically with specific type and number of harvester. It can be considered for formulating mechanized harvesting policy through further research in other areas.

Background: Approximately five million patients on yearly basis are being admitted to the critical care unit around the world. Around (77%) of these patients suffer from pain during their stay in critical care units. Undertreated pain aggravates anxiety, sleep deprivation, agitation, delirium, and depression that often lead to a chronic condition. There are various barriers toward recognition and proper management of pain such as sedation, the presence of endotracheal tube, healthcare providers lack of knowledge etc. Therefore, it becomes essential for the nurses to have the required knowledge related to pain, valid pain assessment tools, and proper management. Objective: The present study aimed at investigating the critical care nurses’ knowledge and attitude towards pain management at a university hospital in Saudi Arabia. Methods: A descriptive cross-sectional design of 112 nurses working at intensive care units and emergency department. The data collected using a knowledge and attitude regarding pain (KASRP) survey. Results: Majority of nurses had inadequate knowledge regarding pain management. Among 112 nurses, only 8 nurses (7.1%) were with good level of knowledge compared by 54 nurses (48.2%) with poor level of knowledge. Results showed significant association between knowledge and attitude and the current position in the ICU (p=0.043). Conclusion: It is mandatory to monitor nurses’ pain management knowledge continuously. As well as to emphasis significance of an educational programs that serve nursing practice.

Background: Access to health-care facilities and essential medicines still remains a worldwide problem, particularly in developing countries. Greater awareness among health-care professional regarding generic drugs may translate into the increased consumption of generic drugs and reduction in healthcare costs wild maintaining the safety efficacy and quality off health-care system.

Aim and Objectives: This study was conducted to analyze the knowledge and perception of generic medicines among MBBS and Nursing students in a medical teaching institute.

Materials and Methods: A questionnaire-based cross-sectional study was conducted among 260 students (172 MBBS, 88 Nursing course) in Government Medical College Jalgaon, to assess knowledge and attitude of students for generic medicines. Descriptive statistics and Kruskal–Wallis test were used to analyze the responses.

Results: Most respondents from MBBS (86%) and nursing course (89%) agree to need more information about how bioequivalence test are conducted for generic medicine. Perception about branded medicines requiring high quality standards as compared to generic medicines was high in both courses’ students with 69.3% of nursing students and 43.6% of MBBS students having wrong perception. About 77.4% of MBBS students and 42% of nursing students responded positively to the statement about generic medicines being cheaper than branded drugs.

Conclusion: Students from both the courses showed eagerness to have more information, were lacking in the knowledge, and had confused attitude toward generic medicines. Proper education and training may impart proper knowledge and change the attitude among students toward the generic medicines.
