Compressive strength and durability properties of m35 grade concrete by replacing sand partially with vermiculite and granite powder and coarse aggregate by re-cycled aggregate

The Construction Industry is one of the industries contributing highest GDP in Indian economy. The material that is most chosen in construction Industry is concrete. Concrete is a material made with Cement, Fine aggregate in the form of sand, Coarse aggregate in the form of gravel and water. With increasing scarcity of sand, construction works are coming to jolt and thereby increasing the need for choosing an alternative material. Vermiculite is a material which after exfoliation can be used as a filler material replacing sand partially without affecting strength much. One more material Granite (by product which is a waste is causing lot of environmental Issues), produced from granite industry, is available in India in several million tons. Coarse aggregate generally used is a crushed aggregate obtained from rocks like granite, basalt and soon. Recycled aggregate is an aggregate which is obtained after demolishing of an existing building, which is a waste causing economical in balance and which if put into use can not only decrease the construction cost but also make this waste into a better use. In the present study, for a M35 grade of concrete, Vermiculite (0, 5%, 10% and 15% of weight of sand) and granite powder (fixed at 10% of weight of sand used) is used to replace sand partially and in the place of normal coarse aggregate, recycled aggregate is used which is 20 mm passing and 12 mm retained After preparation of Mix-Design(1:1.83:2.69 with w/c ratio of 0.38) the concrete cubes are casted to test for compressive strength after curing for 28 days, 56 days and 90 days. Forsec brand super plasticizer is used to take care of workability requirements. Durability test in the form of resistance to attack of sulphuric acid was conducted along with compressive strength. The test results were promising at 10% replacement levels of Vermiculite.

Vaccine storage and distribution between expanded program on immunization and medical store department in tanzania: a cost-minimization analysis

Background In 2016, the Tanzanian government shifted the vaccine supply chain responsibilities from the Medical Store Department (MSD) to the Expanded Program on Immunization (EPI) to reduce costs. However, cost estimates that informed the decision were based on invoice value of vaccines and related supplies, rather than a proper economic evaluation study. Therefore, this study aims to compare the actual storage and distribution costs of vaccines and related supplies between MSD to EPI. Method Micro-costing approach was used to estimate resource use at MSD and EPI for the year 2018. Data were collected through a review of documents, warehouse databases, and interviews with key staff at MSD and EPI. We included both capital and recurrent costs. Microsoft Excel® was used for analysis with input data from the UNICEF forecasting tool, WHOs vaccine volume and capacity estimation tool, diesel generator calculator, and supply chain service fee estimator version 1.02. Results The total vaccine storage and distribution costs were estimated to be USD 1,996,286 at MSD and USD 543,648 at EPI. Distribution and program management costs represented 41% (USD 819,288) and 38% (USD 762,968) of the total costs at MSD, while storage and distribution costs represented 43% (USD 234,423) and 34% (USD 184,620) of the total costs at EPI, respectively. The cost drivers at MSD were fuel and transport (21%), receiving and dispatch (19%) and, program management personnel cost (14%), while at EPI were storage space (20%), program management personnel cost (18%) and fuel and transport (15%). Conclusion The storage and distribution of vaccines in Tanzania via the EPI reduced the vaccine supply chain cost to about 27% of the program costs at MSD.

Physicochemical properties and permeation across mouse skin of non-steroidal anti-inflammatory drugs

The skin provides an effective barrier and only limited number of drugs can penetrate in adequate amounts. This study aims to identify the relationship between the physicochemical properties and permeation across mouse skin of non-steroidal anti-inflammatory drugs in view of their feasibility to transdermal delivery. Biphenylacetic acid, diclofenac base, diclofenac sodium, indomethacin and piroxicam are the drugs studied. Number of physicochemical properties studies were performed. Drug permeation studies across hairless mouse skin were carried out using an in-vitro finite dosing diffusion cell. The relationship between physicochemical properties of the drugs studied and their percutaneous penetration was studied. Purity for the compounds studied ranged from 99.09% to 100% in which 99.89% purity was obtained for diclofenac base. At 7.4, the % ionized of piroxicam was found to be 95.12%, while for other drugs were in the range of 98.01% and 99.96%. The true partition coefficient values in the n-octanol/water system are in the range of 1.85 and 2.85, while in the n-octanol/phosphate system ranged from 2.14 to 3.70. Observed solubility in water, phosphate buffer and n-octanol ranged from 0.033 to 0.322, 0.202 to 0.329 mg per ml, and 2.19 to 16.10 mg per ml, respectively. A linear relationship was found between water solubility and melting point between steady-state rates of permeation across intact and viable skin, between n-octanol solubility and maximum predicted flux and between molecular volume and the ratio of maximum predicted flux. Predicted flux calculated was compared with the experimental data which resulted in a high correlation. Physicochemical criteria which were determined the feasibility of non-steroidal anti-inflammatory drugs studied for transdermal delivery were identified. The relationships obtained in this study provide an essential physical and chemical properties that govern transport of non-steroidal anti-inflammatory drugs across hairless mouse skin.

A comprehensive study of gorvara puta in preparation of rasa bhasma

Ayurvedic formulations are of three types, Herbal, Mineral and Herbo-Mineral. Of which, Herbomineral is prepared either by Khalweeya or by Bhasmeekarana procedures. The quality of Bhasma depends on the number of putas given. Rasa Bhasma is one such kind of a Herbo-mineral preparation which can be obtained by Puta procedure as described in texts of Rasa Shastra. Though there are different procedures mentioned for preparation of Rasa Bhasma, maarana done with Gorvara puta seems to be an apt way to obtain the final product. Puta is the generalised way of heat application used during the pharmaceutical procedures of Rasa dravyas, where the purified organic Metal/Mineral is converted completely into powder form which can be absorbed easily into the body without causing any ill effects. Different types of Puta have been explained for bhasmeekarana of different metals and minerals. Among them, certain putas have been mentioned where Mandaagni plays a crucial role in Maarana (Incineration). These Mandaagniputas are in use of preparing certain Bhasmas like ShilajitBhasma, HaratalaBhasma, GouripashanaBhasma, and PaaradaBhasma. As these drugs are having relatively low boiling and melting points when compared to other dravyas, and are easy to evaporate when exposed to high temperatures, they need a standardized quantum of heat by which they can be transformed into Bhasma. Gorvara puta is one such kind where agni plays a major role in the preparation of Bhasma. So, the present study A Comprehensive Study of Gorvara Puta in Preparation of Rasa Bhasmahas has been under taken.

Review of mentoring in higher education

Mentoring relationships between a senior, experienced faculty member and a junior employee, between a faculty member and an undergraduate or graduate student, or between a senior and a junior student is essential in higher education. The current review aims to emphasize the necessity of establishing organized mentorship programs at national institutions to enhance academic performance, teaching/learning effectiveness, knowledge and skill development, growth and development, research productivity, and community engagement. The mentor and mentee both benefit from the mentoring relationship. Academic advising, preceptor supervision, and supervision of graduation projects are different from the mentoring relationship as they focus on only one aspect of the relationship, whether it is the study plan, the study session, or the project, respectively. Mentoring is a mutually beneficial relationship that calls for integrity, decency, self-assurance, trust, and respect. Educational institutes and colleges should set up a committee to establish a well-organized mentoring program with all the necessary templates for recruiting mentors and mentees, and also for annual evaluation and feedback from all parties involved.

Power outages inport harcourt city: problems and solutions

Frequent power outages arising from poor state of electricity infrastructure is hindering Nigeria’s socio-economic growth. Port Harcourt is one of the foremost cities in Nigeria where business and social activities are becoming rapidly more dependent on electricity. Any power outage, even of the shortest duration, in Port Harcourt City has severe socio-economic impacts and there is no likelihood that the phenomenon would abate even in the nearest future. This research investigated the causes of incessant power outages in Port Harcourt City and suggested remedial measures to reverse the trend. The researcher relied on datacollected from primary sources through personal observations, interviews and discussions with residents of the City and from secondary sources such as the National Bureau of Statistics (NBS), the Manufacturers Association of Nigeria (MAN) and current scholarly literature relating to this research, over a period of twelve months. The study used a descriptive and the non-parametric simple percentages technique in analysing the data so collected and in drawing conclusions. It was found that inadequate power generating capacity, shortage of gas, weak and dilapidated electrical transmission and distribution network, inadequate power infrastructure facilities, etc. are the chief causes of incessant power outages in the Port Harcourt metropolis. The paper recommends, among others, immediate upgrade of existing power infrastructure facilities, review of government policy on domestic gas supply and stiff statutory legislation on vandalism as measures to stabilise electricity supply in the Port Harcourt city.

A review on parkinson’s disease

Parkinson’s disease, first described by James Parkinson in 1817, is a neurodegenerative ailment resulting from the damage of nerve cells in the brain. It is a chronic, progressive, neurodegenerative disorder with an estimated prevalence of 31 to 328 per 100,000 people worldwide. It is estimated that more than 1 percent of the population over age 65 are afflicted with Parkinson’s disease; incidence and prevalence increase with age. There are numerous unanswered questions regarding the diagnosis and management of Parkinson’s disease. Worsening mobility, causing problems with activities of daily living, pain and communication problems due to rigidity of facial muscles, are the main reasons of their decreasing quality of life. This study is focused on the role of psychological variables, which could be associated with quality of life in PD patients. After their identification a discussion about opportunities of improvement patient’s quality of life can be opened. Current drug therapies for human PD with Levodopa or various dopamine receptor agonists offer symptomatic relief and appear to have little effect on the neurodegenerative process. More than 50% of patients with PD treated over 5 years with Levodopa will develop complications such as motor fluctuations and dyskinesia’s. In this scenario, slowing the progression of PD through neuroprotective or restorative therapy is a major focus of research. From a pharmacologic standpoint, current strategies involve interrupting the cascade of biochemical events that leads to death of dopaminergic cells. The significance of many indigenous medicinal plants and their phytoconstitutents in the management of Parkinsonism with minimal side effect profile arise in this context

Secondary metabolites-god gifted arsenal for plants

Plant secondary metabolites refer to various chemical compounds that plants produce. Still, they are not directly involved in essential growth processes like primary metabolites (such as sugars, amino acids, and lipids). The term "secondary metabolite" has generated controversy, as it implies these compounds are of minor importance to plants. "Special metabolites" may be a more suitable term. These metabolites protect plants from both abiotic and biotic stress. The vast diversity of plant secondary metabolites showcases plants' incredible adaptability and versatility, providing an arsenal of chemical tools to defend against herbivores, protect from pathogens, attract pollinators and seed dispersers, adaptability and thrive in environmental interactions. Plants can, therefore, survive under less-than-ideal conditions. The profound impact of plant secondary metabolites highlights the intricate relationship between plants and humanity, opening doors to innovative applications with far-reaching implications.
