COVID-19 vaccination has been reported to have had some side effects or abnormalities. These abnormalities have been reported after 1 - 2 years after the first dosage. In this paper, we want to investigate if this is true in Indian Population using the Indian Health Authority (IHA) data from January 2022 to December 2022. From this database, we selected a sample data which is a portion of the people living in the great of city of New Delhi. All the sample data contained adults who are > 18 years of age and were either vaccinated or unvaccinated (Sample size n = 11,341,189). In the abnormalities, we particularly want to study if there are any changes to iron deficiency in women particularly as Indian women suffer from low Iron naturally. From the results we found out that the abnormalities after a 3-month period after the vaccination were higher than those in nonvaccinated patients. COVID-19 mRNA vaccine was associated with this new development of nutritional anaemia and aplastic anaemia which were detected in the sample study. The risk of other abnormalities like coagulation defects were also increased after the vaccination and there was also no other risks mRNA vaccine and other viral vector vaccine. We conclude that COVID-19 vaccination did increase the risk of anaemia furthermore than it was before. We find that, education, accessibility of more nutritional food and vitamin intake is the solution for the people suffering from anaemia due to vaccine administration.

In recent years, the reliability and continuity of service of powertrains have become major challenges for electric vehicles to enter the mass market. Indeed, defects in powertrains lead to malfunctions in vehicles and reduce their performance compared to conventional vehicles. In this article, we focus on the DC/DC converter associated with the fuel cell in the powertrain. The latter must address the major issues facing fuel cell electric vehicle applications, namely: low mass and small volume, high energy efficiency, reduction of input current ripple, and reliability. This work then consisted of sizing and testing the fault-tolerant DC/DC converter structure selected for P to C vehicles. Algorithms for managing the degraded modes of this converter were developed and implemented experimentally. In this regard, the interaction between P to C and the DC/DC converter was studied. A theoretical simulation approach was used to carry out this work. This approach made it possible, under the most demanding conditions, to achieve very high efficiencies in steady state for both converters: 97.2% for the VS = 400V version and 95.5% for the VS = 200V version, powered respectively by input voltages of 400V and 200V. For input voltages in the lowest range, the efficiency is naturally lower. However, we are confident that this criterion (ƞ ≥ 96%) will be met over the nominal voltage range (between 300 and 600V). This demonstrator has validated the real benefits of a two-stage structure for applications with high input voltage variation, with each stage achieving efficiency in excess of 98%.

This article investigates the root causes of environmental degradation through the lens of entrepreneurial spirit. It examines how a mindset focused on a «calm and secure life» can guide entrepreneurs towards sustainable value creation and social solidarity. Through observation and literature review, the findings suggest that entrepreneurial spirit, driven by wisdom and sharing rather than self-aggrandizement, can uplift collective well-being. The entrepreneur’s true performance lies in their ability to alleviate suffering among the most vulnerable.

The problem raised by the contract of bail in Congolese positive law is much more troubling, it is true that the right to be established all relates to persons, property and obligations. Thus, the resolution of the bail contract seems to be of great concern in the present research. It is generally agreed that the resolution of the contract of bail occurs when one of the parties to the contract through his own fault fails to perform his obligations, having performed the subject matter of their engagement. The questioning posed by the notion of bail, is of the greatest importance, bail being a contract which bears upon two kinds notably the rent of goods and that of labour; this first category will constitute the object of our study. Indeed, in the face of this rental of things, he poses a fun preoccupation as to who may conclude the dance? It should be mentioned that in order to conclude the bail, it is necessary to be a party, and to be a party also it is necessary to fulfill all the applicable conditions.

Traditional fashion aspect Saudi cultural heritage, enriching national international culture fashion sector modern, contemporary way. Research focused identifying most important design principles points follow consider creating contemporary designs inspired Saudi heritage. This contributes preserving Saudi cultural heritage modern way keeps pace current times accepted contemporary Saudi consumer. Research aimed study reasons disappearance traditional Saudi fashion, reasons success spread international fashion, identify successful design characteristics resulting contemporary traditional fashion light research findings. Research followed descriptive analytical approach serve research objectives. Research went following procedures: studying traditional international fashions, identifying target group, conducting interviews target group collect study data questionnaire comprising three axes, analyzing results. Conclusions drawn: Most prominent reasons disappearance traditional heritage fashions difficulty wearing long periods weight, multiple layers, lack development innovation designs colors. Difficulty obtaining high-quality fashions, rarity, high prices, unsuitability practical life women's new tasks labor market. Most important reasons success international fashion sweeping Saudi market, practicality lightness simplicity, suitability all body types, skin types times, variety styles, materials cuts, compatibility culture Saudi society, high quality reasonable prices. Points designer must follow ensure success modern traditional fashion: must available markets light colors materials practical comfortable designs few layers, feminine, short cuts modest models, modern traditional fashion becomes suitable all times, skin types body types.
