This health paper analysis discusses what experts think about the work of the COVID-19 vaccine in the human body. This study is part of general public health literacy. To facilitate the discussion, we obtained data through a Google search engine on many well-known publications concerned with health issues, especially the coronavirus prevention vaccination program. The publication journals we mean are Medpub, Google Book, Esavier, Sagepub, Academic research, Taylor and France, and several other publications. We managed this paper in a qualitative design for secondary data exploration. Meanwhile, our research efforts are carried out. Namely, we use data coding, evaluation, and in-depth interpretation to draw conclusions that can answer the questions of this study validly and reliably. The result is that vaccine programs function by training the immune system to detect and fight viruses and bacteria. Do this; pathogenic molecules must be delivered into the body to elicit an immune response. These molecules, known as antigens, can be found in all viruses and bacteria.

Butt girth welding was a knotty problem for future application of bimetallic clad pipelines. At present, there were two kinds of problems: 1) To decide whether to use a variety of alloy welding procedure or to use corrosion resistant alloy full welding procedure; 2) After selecting the procedure, what kind of welding material should be equipped. In view of the above problems, taking 316L SS or 2205 DSS clad pipe as an example, welding process design and experimental analysis were conduted in this paper. Analysis of welding process from theory, standard and practice pointed out the control of welding hardness under different welding materials and procedure and directional suggestions of welding for bimetallic clad pipelines were provided. Futher the hardness distribution and CVN absorbed Energy test results of different welding processes showed welding quality could be guaranteed only when ENiCrMo-3 welding material was chosen for the whole weld.

When women reach adolescence, they undergo psychological changes that affect their identity; thus, a woman must be able to instill positive values in order to develop a strong sense of self-worth. A woman with an Alpha female figure is depicted in the picture. This study aims to explain the figure of the Alpha female in Islamic female characters, as well as to examine the steps for a Muslim teenager to grow as such an Alpha female through habits. The paper analysis method was used in this study, and the documents used by the researcher were research materials from Henry's book; The Girl Guide, and Felix y Siauw’s; How to Master your Habits. A descriptive qualitative analysis was used to analyze the data. The results of the study indicate that developing the Alpha female through habits in the context of Islamic education can be accomplished by first, providing motivation to improve. Second, training and repetition of activities related to alpha female creation, such as alpha friend, alpha student, professional alpha, and alpha look. The Alpha Female required a third time and consistency to evolve. The fourth is to be an expert, namely being able to form habits, control habits, and dominate habits. The results of this study contribute to the material for a woman in an effort for better self-development.

<p>This paper analysis and investigate the performance of Mobile Broadband (MBB) cellular networks based on the drive tests for suburban areas (at four states) in Malaysia. The data were collected from three main national Mobile Network Operators (MNOs) by using unbranded Samsung Galaxy S6 smartphone handsets, while the period of data collection was between January and February. Two MBB services were considered which are the video streaming and web browsing. For each MNO, the performance data of one MBB service was collected through one a dedicated smartphone. One smartphone was used to browse three different webpages, and One smartphone was employed to stream two YouTube videos with two different resolutions. The study considered four MBB Key Performance Indicators (KPIs), namely: latency, coverage, speed and satisfaction. As per the results, the performance of Fourth Generation (4G) is found superior than that of Third Generation (3G) networks. For instance, a vMOS score of above 3.3 was achieved by 4G networks for MBB video-streaming service, while, score of below 2.6 was attained by 3G networks across all the four studied areas. In addition, it was observed that an enhancement factor of up to 2.86 and 2.83 in download speed was presented by 4G technology in case of video streaming and web page browsing respectively as compared to 3G technology. Examining the performance of current MBB networks is supportive before the deployment of the 5G network. The efficient development of 5G networks in Malaysia can be realized through these study findings, where the existing 4G infrastructures will contribute to supporting the 5G and 6G networks.</p>

With the continuous development of social economy, when people are pursuing economic income, they are also gradually paying attention to their own physical health. They achieve their own physical exercise through sports such as running, fitness, and mountaineering, but these sports often require a certain venue and equipment. Therefore, in view of these sports fitness demands, the ant colony algorithm is introduced to sort out the fitness activities in the context of urban residents’ supply and demand relationships, analyze the demand from both subjective and objective aspects, and explore the lack of supply of sports facilities in this paper. Analysis is conducted from cognitive and national fitness, social needs, habits, and other perspectives. It tries to guide the rational allocation and creation of resources, obtain residents’ fitness awareness and support, and provide corresponding suggestions and support for residents’ fitness activities. The simulation experimental results show that the ant colony algorithm is effective and can support the predictive analysis of the urban national fitness demand.

This research article explores the possible applications of voltage differencing current conveyor (VDCC), as a current mode universal filter and a sinusoidal oscillator. Without the need for an additional active/passive element, a very simple hardware modification makes it a dual-mode quadrature oscillator from the filter configuration. Both the proposed circuit requires only two VDCC and all grounded passive elements, hence a preferable choice for integration. The filter has some desirable features such as availability of all five explicit outputs, independent tunability of filter parameters. Availability of explicit quadrature current outputs, independence in start and frequency of oscillations, makes it a better oscillator design. Apart from prevalent CMOS simulation results, VDCC is also realized and experimentally tested using the off-the-shelf integrated circuit. All the pen and paper analysis such as non-ideal, sensitivity and parasitic analysis supports the design.
