The objective of this study is to explore the influence of predictive maintenance technologies on operational efficiency in manufacturing startups, focusing on implementation processes, operational impacts, and the challenges encountered. This qualitative study employed semi-structured interviews to gather data from key stakeholders in manufacturing startups, including founders, operations managers, and maintenance engineers. A total of 22 participants were interviewed, with the sample size determined by theoretical saturation. The interviews were transcribed verbatim and analyzed using NVivo software. Thematic analysis was conducted to identify and categorize key themes and subthemes related to the implementation and impact of predictive maintenance technologies. The analysis revealed three main themes: Implementation Process, Operational Impact, and Challenges and Barriers. Within these themes, several categories and concepts emerged. The Implementation Process theme highlighted the importance of planning, technology selection, system integration, employee involvement, pilot testing, change management, and post-implementation review. The Operational Impact theme identified efficiency gains, predictive analytics, maintenance scheduling, resource optimization, and quality improvement as significant outcomes. The Challenges and Barriers theme underscored technological challenges, financial constraints, organizational resistance, skill gaps, data management issues, and the necessity of vendor support. The findings indicate that predictive maintenance technologies significantly enhance operational efficiency in manufacturing startups by reducing downtime, increasing productivity, and optimizing resource utilization.

The relative and long-term stability brought about by the Safavid government in Iran made urbanization and its requirements to be reviewed, next to the issue of public health. Some physicians began to run new experiments and produce treatises. One of these outstanding treatises is the Risala Ateshak, written by Imad al-Din Mahmoud bin Masoud Shirazi. For the first time, by writing an independent treatise, he described the symptoms, methods of prevention, and treatment of syphilis. To him, the treatise issued before his, except that of Baha'u'l-Razi, were not discussed and were considered a phenomenon from abroad (the West). He sought to explain the manners of transmission, prevention, and treatment of this disease in different temperaments through the available methods, which were mostly based on herbal medicine. He also expressed his belief about the effectiveness of consuming Chinese wood in treating this disease. The accuracy of this treatise's contents and its writing period makes it clear that syphilis is not an imported disease contrary to the idea that existed. The reason for our ignorance of its existence was the inability to distinguish it from other diseases.

Christianity and Shiite Islam share the religious nature of marriage as compliance with a divine precept and of the family as a sharing and continuation of the divine will preordained for the creation and multiplication of human beings on the face of the earth. I will not dwell on the institution of marriage itself and I will omit to expound its principles, canons and ethics proper to it. I therefore proceed to immediately lay out the essential outlines that characterize the existential philosophy and the role to which parents are called within the family cell. Of this cell they are not the only protagonists, and it must also be said that the cell itself is not an end in itself: the parents are one with the children and the family is one with the society, civil and religious, in which and with which it evolves, lives its religiosity and ethics, and realizes divine wills. The subject of people who make up the family nucleus in the strict sense and the people who gravitate with different duties and in different capacities around it, such as fathers, mothers, sons, daughters, relatives and servants, is vast and complex in its articulations. This is true both as regards their interpersonal relations and their relations with the community environment in the midst of which they stand as elements of edification and support. Indeed, an exhaustive treatment of the personal roles of individuals constituting the family would in itself require extremely detailed and laborious research. Perhaps in no other field has legalism indulged so much as in the treatment and determination of the rights and duties inherent to the members of the family unit. Not only because of their natural belonging to a tribe, clan and family, but also because of their religious identity as subjects of a revealed law, over whom the dominion of faith prevails, or ends up prevailing, over every other instance of ethical, associative and community order. We therefore propose to outline, below, just a few of the complex religious and human implications of the interpersonal relations that regulate and govern the family institution as it articulates itself and becomes the core of the so-called Islamic community.

In Rescher’s view, the cognitive rationality is using dialectic arguments for managing the acceptance of various beliefs and answering the individual’s questions in the best way – an approach that can entail access to rational propositions and true knowledge. While believing in the limitation of rational faculties, Rescher maintains that the intelligence endowed in human being in an evolutional way prepares the ground for his access to the authentic knowledge. The cognitive importance of the criterion of investigating the value of knowledge suggests the existence of an effective factor that can help us in qualitative and quantitative promotion of and deepening our essential information. Skepticism rejects the possibility of accessing authentic information and puts a seemingly strong obstacle on the way to implementing and realizing the goals of argument, and maintains that cognitive rationality is never possible. Rescher considers justification of skepticism based on the wrong assumption that the rational justification of a belief is restricted to the deductive reasoning founded on pre-justified propositions. However, in addition to this, we have the method of hypothetical justification that skeptics ignore.
