The aim of this study is to determine the impact of MSME's affected by the Covid-19 pandemic. We used a panel data design and collected data from 650 respondents randomly from various parts of the country. The data is collected in three rounds: the first from June-July 2020, the second from November-December 2020, and the third from June-July 2021. The analysis found that in (Round 1) 91 percent MSME’s reported decline in production or sale, while in (Round 2) and (Round 3) enterprises reported improvement in production and sale. The study results shows that about 64 percent respondents in average of the three rounds reported increased in debt. Similarly, an average of three rounds, 16 percent and 12.5 percent workers were permanently and temporarily lay-off. Based on the findings of the study its being suggested that short-term and long-term policies should be established for reviving MSME’s.

Social media communication is an important way to visualize the observation of fashion brands in the context of cost and benefit analysis of the paradigm of the fashion market on social media sites. In the context of the definition of the 21st century is a synonym for globalization in the perspective of new liberal economics. In these consequences, social media communication sharpens the direction and dimension of fashion brands among customers because it creates the concept of digital economics and replaces the traditional approach of the fashion markets. In these consequences, the present paper examines the systematic review of the role of social media communication with respect to fashion brands with a study design of an analytical framework. The findings of the study show that India is an emerging market for fashion brands due to its new liberal economics in the aspect of social media communication, but there are lots of challenges emerged in the society of India regarding the adoption of fashion mode in lifestyle. Therefore, it may be managed through the positive role of social media communication in the traditional market of India.
社交媒体传播是在社交媒体网站上时尚市场的成本与收益分析范式的背景下,对时尚品牌进行可视化观察的重要途径。在新自由主义经济学的视角下定义21世纪是全球化的同义词。在这些后果中,社交媒体传播使时尚品牌在消费者中的方向和维度更加尖锐,因为它创造了数字经济的概念,取代了时尚市场的传统方式。在这些后果中,本文通过分析框架的研究设计,对社交媒体传播对时尚品牌的作用进行了系统的回顾。研究结果表明,由于印度在社交媒体传播方面的新自由经济,印度是一个新兴的时尚品牌市场,但在生活方式中采用时尚模式方面,印度社会出现了许多挑战。因此,可以通过社交媒体传播在印度传统市场中的积极作用进行管理。

Hardfacing is carried out to enhance the hardness of the surface of a substrate by depositing a hard and wear resistance filler metal. It is a more cost-effective to construct it out of regular steel and then coat the important layer of welded metal that can ensure the required hardness at the surface. A hardfacing system was developed by employing Robotic Gas Metal Arc Welding for the hardfacing of Stellite 21 on the Mild steel substate. The various components of the hardfacing system and the detailed procedure of hardfacing including the programming the robot, setting the process parameters, conducting the experiments as per Taguchi L9 array and the measurement of hardness were explained. Hardfacing trial 5 gave the maximum hardfacing deposit hardness of 499 Hv.

Multiband patch antenna has a very important part in the communication devices and systems. The benefits in designing and testing of Sierpinski carpet geometries for a low profile, cost effective multiband microstrip patch antenna for wireless standards is reviewed in this paper. The basic structure of the patch antenna is designed using the FR4 substrate with a thickness of 1.3 mm. The designed patch antenna structure is excited using the microstrip feed system. The Sierpinski carpet antenna structure is designed and simulated using High Frequency Structural Simulator (HFSS) software. The available Sierpinski carpet antenna structure in the literature is modified to make the preferred radiation patterns. The effects of the iterations of the modified Sierpinski carpet antenna structure over the generated return loss plots are discussed in this work. Based on the generated multiband behavior in the simulated results, the accomplishment of the designed antenna in the wireless domain was analyzed.

In this study, impacts of nonwoven textile weight, proportion of nettle/polypropylene fibre blend and needle density on oil absorption, nonwoven textile thickness, and nonwoven textile density are examined. The experimental designs of box and behnken are employed to prepare the mechanical needle-punched nonwoven textiles. Nettle content, needle density and textile weight are boosted, oil absorption declines.  Nonwoven textile fabric offers the largest oil absorption (2200%) due to its 30% nettle content, a lesser amount of fabric weight and lower needle density.   The nonwoven fabric thickness reduces as the nettle content rises and the needle density rises. The nonwoven textile thickness reduces as the fabric weight and needle density rise, and as the nettle level increases. At increasing fabric weights, maximum fabric density is achieved. The highest fabric density is produced by higher nonwoven fabric weight (400 g/m2), nettle content (70%) and needle density (350 punches/cm2).
本研究考察了非织造布重量、麻/聚丙烯纤维混纺比例和针尖密度对吸油率、非织造布厚度和非织造布密度的影响。采用箱形和槽形试验设计制备机械针刺非织造布。荨麻含量,针密度和纺织品重量增加,吸油率下降。无纺布具有最大的吸油量(2200%),因为其30%的荨麻含量,较少的织物重量和较低的针密度。随着麻含量的增加和针密度的增加,非织造布的厚度减小。非织造布厚度随着织物重量和针密度的增加和荨麻水平的增加而减小。随着织物重量的增加,织物密度达到最大。最高的织物密度是由较高的非织造布重量(400克/平方米)、荨麻含量(70%)和针密度(350孔/平方厘米)产生的。

Analysis of multiple sleeps and N-policy on a M/G/1/K user request queue in 5g networks base station 5g网络基站M/G/1/K用户请求队列的多睡眠和n策略分析

The primary purpose of green communication is to reduce energy use. The base station (BS) is a radio receiver/transmitter that acts as the wireless network’s hub. It serves as a link between a wired and wireless network. To receive and transmit messages, BS uses a lot of energy. The use of effective sleep and wake-up/setup activities with an acceptable delay helps reduce base station power consumption. In this paper, the BS’s service process is modelled as a finite buffer  queue with close down, sleep, and setup. After a certain number  of user requests (URs) have accumulated in the system, to awaken the BS from multiple sleeps (MS) the -Policy is implemented. To produce probability generating functions, the supplementary variable approach is applied. The UR’s mean delay and the BS’s mean power consumption are calculated using simulation. According to computational studies, multiple sleeps with -policy consume less power than multiple sleeps without -policy.
绿色通信的主要目的是减少能源的使用。基站(BS)是一个无线电接收器/发射器,充当无线网络的集线器。它充当有线和无线网络之间的纽带。接收和发送信息需要消耗大量的能量。使用具有可接受延迟的有效睡眠和唤醒/设置活动有助于减少基站功耗。本文将BS的服务过程建模为具有关闭、休眠和设置的有限缓冲队列。当系统中积累了一定数量的用户请求(ur)后,为了从多个睡眠(MS)中唤醒BS,将执行-Policy。为了生成概率生成函数,采用了补充变量法。通过仿真计算了UR的平均时延和BS的平均功耗。根据计算研究,带策略的多次睡眠比不带策略的多次睡眠消耗更少的能量。

According to computational studies, multiple sleeps with -policy consume less power than multiple sleeps without -policy.","PeriodicalId":443629,"journal":{"name":"THE SCIENTIFIC TEMPER","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130783096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study belongs to the parasites infecting freshwater fish in the district of Bijnor, Uttar Pradesh, India to evaluate the biodiversity of zig-zag eel parasitic fauna, Mastacembelus armatus Lacepede, 1800. Here is a list of parasites we collected during the study, along with information about their host’s species, infected organs and geographical locations. This research adds to our knowledge about the diversity of helminth parasites infected M. armatus collected from River Ganga, Bairaj, Bijnor in Uttar Pradesh and fulfills the gap in the area of fish parasitology in India.
本研究隶属于印度北方邦Bijnor地区淡水鱼寄生虫,目的是评价1800年之纹鳗寄生区系Mastacembelus armatus Lacepede的生物多样性。这是我们在研究期间收集的寄生虫清单,以及有关其宿主物种、受感染器官和地理位置的信息。本研究增加了我们对来自北方邦恒河、拜拉杰、比杰纳河的感染M. armatus的寄生虫多样性的认识,填补了印度鱼类寄生虫学领域的空白。
