INFLUENCE OF THE ADDITION OF Na2CO3 NANO PARTICLES ON PHYSICAL PROPERTIES OF TRANSESTERIFIED CASTOR OIL
Sanjit Kumar Paul
Abstract:
MUDU. SUMAN
There is a global effort to find alternative fluids for industrial applications, and vegetable oil is a promising candidate. However, the use of most vegetable oils as feedstock presents a challenge for industrial use, leading to the development of lubricant fluids from non-edible seed oils. The study you mentioned investigates the influence of nanoparticles on the physical properties of castor oil, which was purified and trans-esterified. Nanoparticles were then dispersed in the trans-esterified oil with concentrations ranging from 0.25% to 1.0% in 0.25% intervals. Fourier Transform Infrared Spectroscopy (FTIR) was used to examine the structures of the samples, and the viscosity, pour point, and flash point were also studied. The results of the study suggest that a small amount of Na2CO3 (0.25%) nanoparticles in the oil could improve the physical properties of the fluid. The nanofluid with 0.25% concentration of Na2CO3 appears to have optimum physical properties. This finding could potentially contribute to the development of more effective lubricant fluids for industrial applications. This study highlights the importance of exploring alternative fluids for industrial applications and the potential benefits of using nanoparticles to improve their physical properties.

Influence of catchment characteristics and anthropogenic activities in changing ecosystem properties of freshwater tropical lake Pichola in Rajasthan, India
Sanjay Meghwal1, Anuya Verma2 and Anshul Kandara3
Abstract:
Freshwater has become one of the most polluted water sources in recent years as a result of astounding developments. As a result, the water quality of these water resources is a constant issue, leading to an increase in the demand for lake water quality monitoring.Regular monitoring of freshwater bodies not only checks water from further deterioration, but also provides a scope to assess the current investments for pollution prevention and control. The current study aims to investigate the effects of alterations, whether direct or indirect, that occurred over lake Pichola, a dry tropical lake of Udaipur, southern Rajasthan, with reference to changes in its water quality caused by several anthropogenic activities in recent years.Several water samples were collected from the periphery of this lake in 2017 and were analysed. The generated data were compared to Lake Badi of Udaipurwhich is set in the same ecological conditions but taken as control lake or in ideal condition.

Dr Vinod Kumar
Abstract:
You have learnt about the role of nutrition and environmental sanitization for maintaining goods. We all know that for happy living, it is necessary to remain healthy and free from diseases. However, you must have seen people suffering from diseases. A disease makes a person weak and vulnerable to more suffering. Do you know that a disease, if prolonged, may also result in disability or death? Diseases may be the result of infection in the body such as jaundice or diarrhoea. They may be a result of faulty eating and living habits (life style) like diabetes and hypertension. Many of these diseases such as hypertension, heart disease and diabetes can only be controlled but not cured. In this lesson, you will study about diseases which occur because of infections and faulty life style. You would also learn about their prevention, cure and control in order to lead a productive life.

CONTRACEPTION: AWERENESS TO MODEREN SOCIETY
Dr. Vinod Kumar Dr. Hariom
Abstract:
Conditional Contraception is the intentional prevention of conception through the use of various devices, sexual practices, chemicals, drugs or surgical procedures. An effective contraception allows a physical relationship without fear of an unwanted pregnancy and ensures freedom to have children when desired. The aim is to achieve contraception in maximum comfort and privacy, with minimum cost and side effects. Some methods, like male and female condoms, also provide twin advantage of protection from sexually transmitted diseases. The burden of unsafe abortion lies primarily in developing countries. Here, contraceptive prevalence is measured among currently married women of reproductive age, and levels have not yet reached those that exist in developed countries.

BIO EVALUATION OF NITROGEN AND OXYGEN BASED HETEROCYCLES
SANJAY KUMAR DR. SHIV BRAT SINGH
Abstract:
Heterocycles based on nitrogen and oxygen are key structural motifs that may be found in a wide variety of physiologically active chemicals. With a particular emphasis on the heterocycles' varied pharmacological activity and therapeutic potential, the purpose of this review is to investigate the bioevaluation of heterocycles of this kind. A broad variety of biological activities, including antimicrobial, anticancer, anti-inflammatory, and antiviral capabilities, are exhibited by heterocycles that contain nitrogen. These heterocycles include pyridines, pyrimidines, purines, imidazoles, and pyrroles. Furans, thiophenes, and coumarins are examples of heterocycles that contain oxygen and possess substantial pharmacological actions. These activities include antioxidant, anticoagulant, and antibacterial properties. When it comes to rational medication design and development, having a solid understanding of the structure-activity interactions of these heterocycles is absolutely necessary. It is also mentioned that the molecular processes that are responsible for their pharmacological actions are explored, which sheds insight on the potential of these substances as therapeutic agents. In addition, current developments in synthetic techniques for the creation of heterocycles based on nitrogen and oxygen are discussed, which makes it easier to access these heterocycles for the purpose of biological assessment. Taking everything into consideration, this review highlights the significance of nitrogen and oxygen-based heterocycles in the process of drug discovery and development, highlighting the potential role that these heterocycles play in tackling a variety of therapeutic issues.

THE LIFE CYCLE OF BRYOPHYTA
SUDHEER KUMAR KUSHWAHA DR. AWADESH KUMAR YADAV
Abstract:
The group of plants known as bryophytes includes liverworts, mosses, and hornworts. Bryophytes are terrestrial plants that include gametophytes that are photosynthesis-dependent and permanent, and sporophytes that are photosynthesis-dependent and ephemeral. Bryologists recognize a few lower groups in addition to the two categories of monoicous and dioicous plants, which are classified according to the sexual system of these plants. There seems to be a connection between the sexual systems of bryophytes and their breeding systems. In dioicous species, out-crossing occurs, whereas in monoicous species, self-fertilization takes place. The low frequency of fertilization and the rarity of sporophytes that are associated with dioicous species may be attributed to a number of factors, including biassed sex ratios, geographical separation of sexes, and the lack of males or the inability of males to express sex among populations. Following fertilisation and the growth of sporophytes, bryophytes generate spores, which are responsible for the creation of new plants. Bryophytes, on the other hand, are capable of alternative types of reproduction, including asexual structures such as gemmae, propagules, and the regeneration of pieces that are capable of forming new plants.

FREEZING TRANSITIONS IN A TWO-DIMENSIONAL SYSTEM OF MODEL ULTRASOFT COLLOID AND PAIR CORRELATION FUNCTIONS
Anuj Kumar Dr Nand Kumar
Abstract:
The radial distribution functions g(r) for the system of psections that interact through a Hertzian potential with an exponent η equal to 5/2 are compared with the results from experiments and molecular dynamics simulations reported in Reference. These numbers correspond to scaled number densities. Additionally, a strength parameter of 496kBT is included in the analysis. In spite of the fact that HNC is often linked with psection systems that have long-range interaction potentials, it has been shown to be successful in this specific instance of core-softened potentials. PY IET, on the other hand, produces exceptional results when applied to hard potentials that are sort-ranged. For the purpose of allowing you to evaluate the performance of HNC in comparison to that of PY closure, we have also provided the PCF curves that were generated by PY IET. There is a significant degree of qualitative agreement between the experimental curves and the simulation curves, and the g(r) that was computed using HNC and PY IETs is practically identical to both of them. It is seen that the HNC considerably underestimates the correlations as we go from low densities to high densities; nonetheless, while we are at low densities, the agreement is remarkable in terms of its quantitative quality. \r\n
