Role of Laser in Oral and Maxillofacial Surgery: A Review of Literature

Lasers have been used in dentistry for diagnostic and therapeutic purposes for more than 30 years, and are an indispensable instrument in any modern dental surgery. The  use of lasers enables new treatment methods to be employed in order to meaningfully supplement traditional therapies. The purpose of this paper is to overview the use of laser as use widely. In this paper, we are summarized the role of laser in different oral and maxillofacial disease by review of literatures. Oral and maxillofacial surgery is a vast branch of dentistry which includes procedures ranging from simple extraction to pathologies of both the hard and soft-tissues.Based on extensive review of literature, certain conclusion can be made regarding the use of lasers&nbsp

Synthesis and Characterization of Multiwalled Carbon Nanotubes (MWCNTs) Dispersed ZnS Based Photocatalytic Activity

Zinc Sulfide (ZnS) based photocatalytic activity has been focused in solar hydrogen production and water treatment process because to their very strong redox reaction. Due to wide visible light range, ZnS becomes a promising semiconductor in formation of photocatalysts. The bandgap energies (Eg) of all prepared samples ZnS NCs and MWCNTs/ZnS nanocomposites were evaluated and Methylene Blue (MB) degradation study occurring of ZnS NCs and MWCNTs/ZnS nanocomposites were evaluated under visible light using UV-visible spectroscopy. The author found that removal rate of MB is greater than 95 percentage in the presence of MWCNTs/ZnS composites photocatalysts after 50 min. Crystalline grain size and structure of photocatalyst were characterized by X-ray Diffraction (XRD) spectroscopy. The enhancement of photocatalytic activity can be associated by many factors like a suitable band gap in visible region, crystalline structure of nanocomposites and particle size in nanometer (nm) of the MWCNTs/ZnS nanocomposites. The suitable photocatalytic reaction and mechanisms of MB degradation also included in this article

Design of Automated Rainout Shelter to Conduct Experiment on Drought Tolerant Maize Genotype

Uneven and low precipitation areas of Nepal are continuously suffering from drought and received low productivity because of unavailability of suitable drought tolerant maize genotype. An attempt has been made first time in Nepal by constructing an automated rainout shelter with soil moisture based automated drip irrigation system at National Maize Research Program in 2018-2019 to conduct an experiment on drought tolerant maize genotype. The rainout shelters automatically covers the cropping area as soon as the rain sensor received a single drop of precipitation and also if the light intensity decreased to value set in the control panel. Likewise, the soil water level in different treatments were maintained on the basis of the treatment controlled with automatic drip irrigation system set to irrigate at threshold value set in the microcontroller. The complete system had found very useful in determining accurate amount of water required to cultivate drought tolerant maize genotype. We have tested drought tolerant variety RampurSo3Fo8 under 10 level of irrigation and it was determined that 495.2 mm of water is maximum level of water to produce highest yield of 3.32 t/ha whereas 445.6 mm to 247.6 mm of water could can be manage to produce competitive yield without any reduction. An experiment under such kind of infrastructure provide useful information on irrigation management practices required for drought variety in the natural environment. The research output also guides farmers and agriculturist in making Nepalese agricultural more sustainable, mechanized and productive

Productivity of maize (Zea mays L.) as affected by varieties and sowing dates

Genotypic yield potential of maize varieties is greatly affected by sowing dates. In order to investigate the effects of sowing dates and varieties on the grain yield of maize, the field experiment was carried out at research field of National Maize Research Program (NMRP), Rampur, Chitwan, Nepal from April 2009 to March 2010.  Three varieties namely Rampur Composite, Arun-2 and Gaurav were sown at every week. The results of experiment showed that interaction effect of variety and sowing date on grain yield of maize was significant. Rampur Composite produced highest grain yield (6.1 t/ha) in August and lowest yield (2.6 t/ha) in May. Similarly Arun-2 produced highest yield (4.6 t/ha) in August and lowest yield (2.1 t/ha) in May. Gaurav produced highest grain yield (5.1 t/ha) in September followed by 4.9, 4.8 and 4.6 t/ha in February, July and August respectively and lowest yield (1.5 t/ha) in November. The sowing date was highly significant on grain production. The highest grain production was 5.1 t/ha in August followed by in February (4.9 t/ha), September (4.6 t/ha) and March (4.4 t/ha) respectively. The lowest grain yield was produced in May (2.4 t/ha). Therefore it was concluded that August planting was best for higher grain production of maize varieties (Rampur Composite, Arun-2 and Gaurav) in terai region of Nepal

Introduction to Alginate: Biocompatible, Biodegradable, Antimicrobial Nature and Various Applications

Alginate is a polysaccharide that has found numerous applications in the domain of pharmaceutical science, paper and textile industry, food industry, dental applications, welding roads, mucoadhesive properties, scaffolding, biomedical and engineering due to its cost-effective nature, film forming ability, gelling, biocompatibility, biodegradability, nontoxic, non-immunogenic, readily availability, antimicrobial nature. Hydrogels of alginates play a crucial role in well-controlled or sustained release drug delivery, wound healing, and tissue engineering. This book chapter will provide a detailed overview of Alginate and its applications. To the best of our knowledge there no such type of informative data is available on Alginate and its relation with drug susceptibility. Here we more focused on the antibiotic capability of Alginate and its association with bacterial resistance

Developing Standard Treatment Workflows—way to universal healthcare in India

Primary healthcare caters to nearly 70% of the population in India and provides treatment for approximately 80–90% of common conditions. To achieve universal health coverage (UHC), the Indian healthcare system is gearing up by initiating several schemes such as National Health Protection Scheme, Ayushman Bharat, Nutrition Supplementation Schemes, and Inderdhanush Schemes. The healthcare delivery system is facing challenges such as irrational use of medicines, over- and under-diagnosis, high out-of-pocket expenditure, lack of targeted attention to preventive and promotive health services, and poor referral mechanisms. Healthcare providers are unable to keep pace with the volume of growing new scientific evidence and rising healthcare costs as the literature is not published at the same pace. In addition, there is a lack of common standard treatment guidelines, workflows, and reference manuals from the Government of India. Indian Council of Medical Research in collaboration with the National Health Authority, Govt. of India, and the WHO India country office has developed Standard Treatment Workflows (STWs) with the objective to be utilized at various levels of healthcare starting from primary to tertiary level care. A systematic approach was adopted to formulate the STWs. An advisory committee was constituted for planning and oversight of the process. Specialty experts' group for each specialty comprised of clinicians working at government and private medical colleges and hospitals. The expert groups prioritized the topics through extensive literature searches and meeting with different stakeholders. Then, the contents of each STW were finalized in the form of single-pager infographics. These STWs were further reviewed by an editorial committee before publication. Presently, 125 STWs pertaining to 23 specialties have been developed. It needs to be ensured that STWs are implemented effectively at all levels and ensure quality healthcare at an affordable cost as part of UHC
