Analysis of the Performance of IoT Networks in Acoustic Environment by using LZW Data Compression Technique

The Internet of Things (IoT) has experienced phenomenal growth, opening up a wide range of applications in many settings. Due to the properties of sound propagation, IoT networks operating in acoustic environments in particular present special difficulties. Data compression techniques can be used to minimize overhead and maximize resource utilization in these networks to increase performance. The performance of IoT networks in acoustic environments is examined in this study, with a focus on routing overhead, throughput, and typical end-to-end delay. Lempel-Ziv-Welch (LZW) data compression is used to reduce data size and boost communication effectiveness. Three well-known protocols—MQTT, CoAP, and Machine-to-Machine (M2M)—are assessed in relation to acoustic Internet of Things networks. To mimic different acoustic conditions and collect performance metrics, a thorough experimental setup is used. Different network topologies, data speeds, and compression settings are used in the studies to determine how they affect the performance metrics. According to the analysis's findings, all three protocols' routing overhead is greatly decreased by the LZW data compression approach, which enhances network scalability and lowers energy usage. Additionally, the compressed data size has a positive impact on network throughput, allowing for effective data transmission in acoustic contexts with limited resources. Additionally, using LZW compression is seen to minimize the average end-to-end delay, improving real-time communication applications. This study advances knowledge of IoT networks operating in acoustic environments and the effects of data reduction methods on their functionality. The results offer useful information for network engineers and system designers to optimize the performance of IoT networks in similar situations. Additionally, a comparison of the MQTT, CoAP, and M2M protocols' suitability for acoustic IoT deployments is provided, assisting in the choice of protocol for particular application needs

Isolation and Characterization of Tamarind Seed Gum as Pharmaceutical Excipient

Objective: Tamarind seed gum (TSG) is a polysaccharide having galactomannans as chemical constituents, and it is extracted from the seeds of Tamarindus indica L (Family Fabaceae). Generally, polysaccharides play most important roles as thickening, gelling, emulsifying, hydrating, and suspending agents in pharmaceutical formulations. The purpose of this work was to investigate the film coating potential of tamarind seed gum (TSG), using paracetamol as a model drug. Material and Method: Tamarind seed gum, Paracetamol tablet, Hydroxypropylmethylcellulose Sodium alginate, and Distilled water. Core tablets of paracetamol were obtained from a pharmacy shop in the local market and the physicochemical properties such as weight, hardness, friability, and disintegration time were evaluated. Aqueous coating solution consists of 2% TSG hydroxypropylmethylcellulose (HPMC) (2% w/v), and sodium alginate (1% w/v) were prepared and used to coat the tablets by dip coating technique. The coated tablets were evaluated. Result: The coated tablets showed lower friability; increased disintegration time (14 min) as compared to the core tablet (3 min), improved hardness, and improved drug release profile. TSG film coated batches showed drug release profile up to 10 hrs and HPMC coated batches showed drug release up to 12 hrs. The results of drug release rate of TSG film is very closed to HPMC release profile. This TSG have good film formers properties. It is a promising natural, biodegradable, cheap and eco-friendly film former, particularly when masking of taste or objectionable odor in a solid dosage formulation is desired. It can be used as carrier in sustained release formulation.Conclusion: On the basis of result we can conclude that TSG has promising properties as pharmaceutical excipient. It could be used in the formulation of sustained release matrix as coating agent. &nbsp

Analyzing Mediating Factors in Job Satisfaction Within the Retail Superstore Environment

Employee devotion to the organization is a key factor in determining whether an organization will succeed in the competitive market. Employee job satisfaction is therefore a critical factor. Employee satisfaction leads to full commitment and motivation to perform at their peak levels, enhancing customer value and advancing business goals. When employees receive enough compensation (salary, bonus, and provident fund), allowances, and insurance, as well as better working conditions, recognition for their efforts in the workplace, opportunities for training and development, and vacation benefits from their employer, they are satisfied with their jobs. The goal of the study is to identify the factors that influence an organization's employee job satisfaction. The article's objective is to quantify the degree to which the mediating factors have an impact on worker job satisfaction

Towards Automated and Optimized Security Orchestration in Cloud SLA

In cloud computing, providers pool their resources and make them available to customers. Next-generation computer scientists are flocking to the cutting-edge field of cloud computing for their research and exploration of uncharted territory. There are still several barriers that cloud service providers must overcome in order to provide cloud services in accordance with service level agreements. Each cloud service provider aspires to achieve maximum performance as per Service Level Agreements (SLAs), and this is especially true when it comes to the delivery of services. A cloud service level agreement (SLA) guarantees that cloud service providers will satisfy the needs of large businesses and offer their clients with a specified list of services. The authors offer a web service level agreement–inspired approach for cloud service agreements. We adopt patterns and antipatterns to symbolize the best and worst practices of OCCI (Open Cloud Computing Interface Standard), REST (Representational State Transfer), and TOSCA (Topology and Orchestration Specification for Cloud Applications) with DevOps solutions, all of which API developers should bear in mind when designing APIs. When using this method, everything pertaining to the cloud service, from creation to deployment to measurement to evaluation to management to termination, may be handled mechanically. When distributing resources to cloud apps, our system takes into account the likelihood of SLA breaches and responds by providing more resources if necessary. We say that for optimal performance, our suggested solution should be used in a private cloud computing setting. As more and more people rely on cloud computing for their day-to-day workloads, there has been a corresponding rise in the need for efficient orchestration and management strategies that foster interoperability

Случай раннего выявления метастазов в бедренной кости у больного раком полового члена

Background. Bone metastasis is very common in the advanced stage of numerous carcinomas. In penile carcinoma, lymph nodes metastasis is somehow common but it is very rare reported to be secondary from penile cancer. till the date, there are only few cases of penis carcinoma reported bone metastasis in literature worldwide.Case Presentation. Herein, We presented a 51-year-old Nepalese male with squamous cell carcinoma of penis. computed tomography (ct) scan of the patient revealed that there was carcinoma involving glans penis and precure with bilateral external &amp; internal inguinal lymphadenopathies. After then, the patient was under gone for partial penectomy and bilateral inguinal lymphadenectomy and complete 6-cycle chemotherapy. After one year of treatment, patient developed thigh pain and headache and he advised to have magnetic Resonance imaging (mRi) of brain, 99mTc-MDP whole body bone scan and ct scan of pelvis and thigh. The examination report reveals that there was a sclerotic change in vertex of skull bone and moderate 99mTc-MDP uptake in right proximal shaft of femur just below the neck d/d metastasis. The histopathological examination of the true cut biopsy taken from the lesion of the femur showed metastatic keratinizing squamous cell carcinoma which is rare case of femoral shaft bone metastasis secondary from penile carcinoma. Then patient was sent for surgical reconstruction of femur. Based on the case studies review femur shaft bone metastasis from penile cancer is extremely rare.Conclusion. The best of our knowledge; this is the first early detected bone metastases to shaft of the femur in a patient with penile cancer. early diagnosis helps to radical treatment as well as palliative treatment. surgery is the preferred option of the treatments, especially for metastatic foci in the long bones.Аннотация Метастазы в кости часто встречаются на поздних стадиях разных злокачественных новообразований. Для рака полового члена характерно лимфогенное метастазирование, костные метастазы встречаются очень редко. На данный момент в мировой литературе зарегистрировано лишь несколько случаев рака полового члена с метастазами в кости.Описание клинического случая. Мы представляем описание клинического случая плоскоклеточного рака полового члена у 51-летнего мужчины из Непала. Компьютерная томография (КТ) выявила рак полового члена, локализованный на головке и крайней плоти с двусторонней паховой лимфаденопатией. Пациенту выполнена частичная пенэктомия, двусторонняя паховая лимфаденэктомия, проведено 6 курсов адъювантной химиотерапии. Через один год после завершения лечения у пациента появились боли в бедре и головная боль, рекомендована МРТ головного мозга, сканирование костей скелета с 99mTc-MDP и КТ таза и бедра. Обследование показало наличие склеротических изменений в теменной кости черепа и умеренное накопление 99mTc-MDP в проксимальном отделе правом бедренной кости ниже шейки. Гистологическое исследование биоптата, взятого из очага в бедренной кости, выявило метастаз ороговевающего плоскоклеточного рака, что является редким случаем метастазирования рака полового члена в диафиз бедренной кости. Пациент был направлен на хирургическую реконструкцию бедренной кости.

Представлен первый случай раннего выявления костных метастазов в диафизе бедренной кости у пациента с раком полового члена. Ранняя диагностика помогает как радикальному, так и паллиативному лечению. Хирургическое вмешательство является предпочтительным вариантом лечения, особенно при метастатических очагах в длинных костях

Pre-operative Hypoglycemia in Patients Presenting for Surgery: A Hospital Based Cross-sectional Study

Introduction: Peri-operative glycemic control is an important factor for post-operative recovery and is well protocoled for diabetic patients in every setup. It is not always so with non-diabetic patients. This study aimed to observe the pre-operative glucose level and prevalence of hypoglycemia in patients presenting for surgery and its association with the duration of nil per oral period (NPO), age and intravenous fluids used in the pre-operative period. Methods: A cross-sectional study was conducted in the Department of Anesthesiology in a Nepalese medical college including all the patients posted for elective surgery over a period of three months. Socio-demographic and clinical details of the participants were collected in the operating theatre. Duration of&nbsp; NPO period and intravenous fluid prescribed in the pre-operative fasting period were recorded. A glucose strip test was performed on all the participants. Results: Participants were found to have fasted for an unnecessarily longer duration (12.84±2.27 hours). The incidence of hypoglycemia in patients posted for elective surgery was very high (43.3%). Ringer lactate and normal saline were equally prescribed (38.4%) and dextrose-normal saline was prescribed in the rest of the participants. Gender and type of intravenous fluids were positively correlated whereas NPO period was negatively correlated in overall participants though statistically insignificant. In hypoglycemic participants, we observed that lower glucose was influenced by pre-operative fluids, age and NPO duration. Conclusion: Pre-operative use of glucose-containing fluids during NPO period is an important step to prevent hypoglycemia and related consequences
