Celiac disease is a chronic inflammatory disorder triggered by the ingestion of gluten-containing foods in genetically susceptible individuals. This multifactorial disease has both genetic and environmental components, with gluten serving as the environmental trigger and specific genetic variations in the major histocompatibility complex region contributing to the genetic predisposition. Contrary to previous assumptions, celiac disease is not a rare disorder, with a global prevalence estimated at approximately 1%. However, it often remains under-recognized because many affected individuals do not exhibit the classic gastrointestinal symptoms associated with the condition. Instead, they may present with nonspecific manifestations of nutritional deficiencies or may be entirely asymptomatic. Celiac disease is associated with an increased incidence of autoimmune disorders, and its identification in asymptomatic or silent cases is crucial for managing associated conditions and preventing long-term complications such as lymphoma. The relationship between celiac disease and other autoimmune disorders, particularly type 1 diabetes, suggests a potential trigger role for gluten. In this article we review the development of celiac disease, including its types, pathogenesis, clinical features, and associated diseases or complications. We will also discuss available tests, treatments, and preventive approaches related to this subject.

Cervical squamous cell carcinoma is observed as the second major cause of mortality worldwide. A highly conserved mitogen-activated protein kinase (MAPK) signaling pathway occurs in a wide range of cellular processes which includes differentiation, proliferation, migration, senescence, and apoptosis. MAPK pathway can be activated by various extracellular signals, capable of generating responses as per the cell type. Thus, alteration of the EGFR receptor in this particular pathway leads to the condition of cancer due to abnormal activation of receptor tyrosine kinases. The characteristic features of microRNA (miRNA) which are endogenous, single-stranded, small non-coding RNA for their role in RNA silencing and post-transitional regulation of gene expression have been studied over the years. The miRNA functions by base pairing with the complementary sequences within the mRNA molecule. One such miRNA, miR-329-3p has a critical tumor suppressor role in the MAPK pathway, however, is least understood. Therefore, miRNA could be considered as a potential biomarker for diagnosis, prognosis, and therapeutic purposes and brought out to its fullest use to mankind.

The intensive integration of Azerbaijan into the global economy, mainly through international gas and oil pipeline construction, has led to significant archaeological research in the past two decades. The construction of the Baku-Tbilisi-Ceyhan oil pipeline (BTC) and the Southern Caucasus Pipeline gas pipeline (SCP) prompted a four-year archaeological fieldwork program, followed by a six-year post-excavation program. The current work applied an interdisciplinary approach using various instrumental methods for studying ancient artifacts found during those projects. The thermogravimetric method and differential thermal analysis were employed to obtain insights into the production technology of the ancient pottery and information about the mineralogy of the ceramic sherds. The complex processes involved in firing the ceramic paste have been studied extensively, and patterns in mass loss ratios during different temperature ranges have been established. In total, 15 samples were investigated, and the thermogravimetric analysis of ceramic shards revealed that the firing temperature of the samples was in the range of 700 °C. XRD analysis confirmed the presence of quartz, feldspar, and clay minerals in the ceramic samples. The presence of calcite and other specific minerals is subject to the origin of the ceramic materials. The results obtained from this multidisciplinary approach provide insights into the firing technology and the origin of the ceramic samples.

Mineral oil-based cutting fluids are hazardous and non-biodegradable, and their widespread usage has had a terrible effect on the environment and living things. The creation of a novel, ecologically sustainable cutting fluid technology is essential to avoid the above crisis. Commercial mineral oil alternatives are considered to possess identical lubricating properties as vegetable oils. Most vegetable oils are edible, so waste-cooking sunflower oil (WSO) is selected from this group to serve as the base stock for the green cutting fluid. The green cutting fluid is created using silicon dioxide nanoparticles as an additive and food-grade emulsifiers like Tween 80 and Span 80. According to the experimental findings, 0.05 weight percent silicon dioxide nanoparticles in the green cutting fluid performed better on a pin-on-disc tribometer.

The present work investigates the design and analysis of a staircase lift, which can be used as a Material Handling System. A staircase lift is a mechanical device for lifting people and wheelchairs up and down the stairs, who may find difficulty in doing so themselves. For sufficiently wide stairs, a rail is mounted to the treads of the stairs. A chair or lifting platform is attached to the rail. A person on the chair or platform is lifted as the chair or platform moves along the rail, old age and goods are to be carried across the staircase. A staircase lift is a type of lift that can be mounted on the staircase without altering civil structure. Not only altering, but the person need not change the seat from the wheelchair to the staircase lift, there is a foldable supporting rod for the staircase lift which directly attaches to the wheelchair. This lift runs on electric power and consists of a motor, reduction gearbox, rope drive, two rails and a sliding chair. In this system, we use a DC motor for changing the polarity of the power supply which will make the motor run in reverse direction. Advantages over the conventional hydraulic lift are no civil structure and alteration is required, low cost, less bulkiness, less power, less maintenance required. Easy design, easy installations can be of industrial use too. Moreover, considering some drawbacks due to weight carrying capacity completely depends upon the capacity of the motor. There is a lot of scope for further modification in the project as using a monorail instead of two, using a belt drive or chain drive instead of a rope drive. Incorporation and automation/timer unit will ease the use of the device. Rack and carrier arrangement for using the device for a curved staircase and use of work & roller reduction gear assembly.

The Plastic Waste Management Amendment Rules, 2021, already prohibit the manufacture, import, stocking, distribution, sale, and use of plastic carry bags having a thickness of less than 75 microns. They also provide for a ban on plastic carry bags with a thickness of less than 120 microns as of December 31, 2022. So, there is an increasing demand for paper bags. The already existing paper bag-making machines are expensive and consume 25-50 square meters for their operation. A machine whose initial cost is less, which does not require large space consumption and operates with simple technologies, can be used for small-scale production. This will help the manufacturer earn money through the small-scale production of paper bags. The demand for paper bags is continuously increasing, so this project aims to develop an economical and easily fabricable machine with simple methods that promote the use of paper bags instead of plastic carry bags and helps reduce the impact on the environment.

Electrified transportation will help to reduce greenhouse gas emissions and petrol prices. Electrified transportation demands that a wide variety of charging networks be set up, in a user-friendly environment, to encourage adoption. Wireless electric vehicle charging systems (WEVCS) can be a potential alternative technology to charge electric vehicles (EVs) without any plug-in problems. This paper outlines the currently available wireless power transfer technology for EVs. In addition, it also includes wireless transformer structures with a variety of ferrite shapes, which have been researched. WEVCS are associated with health and safety issues, which have been discussed with the current development in international standards. Two major applications, static and dynamic WEVCS, are explained, and up-to-date progress with features from research laboratories, universities, and industries is recorded. Moreover, future upcoming concepts-based WEVCS, such as ‘‘vehicle-to-grid (V2G)” and ‘‘in-wheel” wireless charging systems (WCS) are reviewed and examined, with qualitative comparisons with other existing technology.

From an industrial, environmental, and scientific standpoint, the creation of renewable and sustainable products to replace fossil fuels is an important concern in this decade. Due to the growing use of different lubricant types, the majority of which are mineral-based, there is an unavoidable flow of mineral-based lubricants into the environment. Another issue is using cooking oil that pollutes the environment when discarded. Both of these issues can be resolved by creating bio-based lubricants from discarded cooking oil. This article discusses formulating a green cutting fluid made from used cooking oil. This enables the use of waste oil as a cutting fluid while retaining its tribological and environmental characteristics. In order to compete in the market, biodegradable cutting fluid might gain from decreased costs for used natural oils. The many components and trends that make up this topic are briefly covered in this article, along with waste cooking oils’ potential application as a bio-based lubricant.

Due to declining supplies of once-affordable fossil fuels, research into renewable energy sources is being prioritized. Using solar energy for passive cooling and heating can significantly reduce the demand for primary energy sources. In this survey, we look at how changing a few variables might affect how well a solar air heater functions. It helps researchers learn more about these systems’ development, properties, and potential uses. This research analyses the current literature to emphasize the value of thermal properties. Focusing on laminar sublayer creation and increasing the heat transfer coefficient, it explores ways to increase the efficiency of solar air heaters. After reviewing several articles, it has been determined that rib roughness elements and their geometric characteristics play a significant role in enhancing the thermal performance of solar air heaters. The relative roughness height, pitch, angle of attack, and width are all important factors to consider.
