Abstract

Producing good quality goods should be the primary responsibility of the manufacturer, and ensuring good quality services is the responsibility of the government. Utilizing good quality services is the basic human right of each and every individual. Provision of efficient and effective quality health care to the public is one of the ethical principles. Assessment of quality of health care provided to the public can be done through clinical audit system. Clinical audit is a quality improvement process that seeks to improve patient care and outcomes through systematic review of care against explicit criteria, and the implementation of change. Clinical audit results in improved clinical practice, increased efficiency, better clinical outcomes or more cost-effective service. In India, there is hardly any audit system in dentistry though the concept has existed since a long time. This review is an insight on methodology of clinical audit and the need for implementation of such a system for dental practice in Indian scenario.

Abstract

Modern building planning is influenced by many factors and often, there is a trend to adopt a form that has irregular shape in plan and also has variation in height of storeys. Due to the varied use, a building is planned for; variations in the load acting on different floors may also differ. More irregularities can be present like non continuation of members in all the floors, or absence of members, and also having additional members in some of the storey levels. Such buildings will have maximum risk, when compared to conventional framed structures, when seismic forces come into play. This paper highlights the various aspects in the performance of buildings, and also suggests some remedies for the problems.

Abstract

Over head water tanks, made up of reinforced concrete are more common due to the fact that it can be easily cast in any desired shape and size. The durability of such tanks may get affected due to external agents like wind, air etc. and needs maintenance periodically. The corrosion of reinforcement is the major distress of any reinforced concrete structure, and these tanks also face the same problem. Once the corrosion of steel happens, the satisfactory performance of the reinforced concrete tanks gets affected and distress starts in the form of minor cracks. If left unchecked, the effects of corrosion may propagate further and may lead to structural failure in due course. In this case study, many overhead tanks made up of reinforced concrete were studied, and their types of distress along with remedial measures are suggested.

Abstract

A man made structure becomes stronger as its size is increased. They find application in the roofing of buildings. Geodesic spheres are arrangements of polygons in great circles that approximate a true sphere. Of all structures built from linear elements, a Geodesic Dome has the highest ratio of enclosed volume to weight. This paper highlights the uses and applications of geodesic domes along with their geometrical properties.

Abstract

Fire outbreak in a building will, obviously, create panic and confusion in people occupying it. Fire causes slight to full damage to properties, persons and also in worst cases, leads to collapse of structures. If the fire intensity is more, there are chances that it may affect the neighbouring structures. Fire resistance of different building materials will not be the same, and their behavior during fire will be a major issue, once fire outbreaks. This paper highlights some of the aspects of fire safety in a building, and also some of the precautions we can take during such fires.

Abstract

Masonry structures should be protected from the effects of surrounding atmospheric agents like wind, water etc. Increasing its durability by proper maintenance is also a required aspect . Coatings by ferro cement is an adopted technique to protect the masonry walls against detrimental factors which attack it.In this study different types of masonry walls where tested for compression and their performance was judged to estimate whether use of ferro cement coatings can be applied on masonry or not to protect them.

Abstract

The chrysopid, Mallada astur (Banks), recorded for the first time as promising egg and early larval predator of O. arenosella in interior Karnataka was evaluated for its predatory efficiency. This predator is predominant on coconut and palmyrah palms of 30m height. Its short life cycle (24.5 days) on a combined diet of eggs and larvae of O. arenosella, high fecundity per female (mean=102.3 eggs), and its ability to thrive in the larval galleries of O. arenosella, strongly support its utilization as a biocontrol agent during peak period of infestation (September-February) in interior Karnataka. Net house studies revealed that release of one M. astur larva (4 day old) per severely infested leaflet with about 35·50 neonate larvae will effectively reduced the population of the pest within a week.

Abstract

A systematic surveillance of coconut leaf eating caterpillar, Opisina arenosella Walker and its important parasitoids was carried out on young and old coconut palms in interior and coastal areas of Karnataka during 1996-1997. Among the parasitoids recorded, Apanteles taragamae Viereck was active during summer and rainy seasons in coastal and interior areas, respectively. Meteoridea hutsoni Nixon and Brachymeria spp. predominated during winter and summer seasons, respectively. and showed their perfect synchronization with high population of O. arenosella. Studies on the effect of abiotic factors on the activity of these parasitoids showed variation between the species, regions and palm ages.

Abstract

Surveys in coastal and interior Karnataka during 1996 and 1997 revealed the occurrence of four larval, one larval-pupal and thirteen pupal parasitoids and eleven predators of Opisina arenosella Walker. Eight hyperparasitoids were also recorded.

Abstract

One hundred and sixty Oryctes rhinoceros (L.) beetles, collected from 30 villages of Godavari districts of Andhra Prasesh were screened for baculovtrus disease. Examination of gross morphology of midgut and giemsa-stained smears of midgut aspirates and squash showed typical symptoms of baculovirus infection in 53.1% beetles. Similarly, O. rhinoceros grubs from 14.0% breeding sites in Gudapalli village and 20.0% breeding sites in Allavaram village showed the disease symptoms with 8.4% and 4.0% grub infection respectively. Present survey reveals the presence of Oryctes baculovirus in Andhra Pradesh.

Abstract

Objectives: To investigate the influence of storage methods of whole blood samples on Deoxyribonucleic acid (DNA) quality.
Method and materials: Whole blood samples were collected from 90 patients reported to the Government Tertiary-care Dental College and Hospital, Tamil Nadu, India. The blood samples were stored at three different temperatures -80 °C, -20 °C, 4 °C which were analyzed for DNA quality immediately within 4 h and after a storage period of 60 days. Quantification of DNA in the sample was recorded using a spectrophotometer..
Results: The average concentration of isolated DNA ranged from 0.5 ng/μl to 154.2 ng/μl with purity A₂₆₀/A₂₈₀ratio ranging from 0.7 to 2.0. The mean DNA concentration H = 97.2 (p = 0.001) and purity H = 80.1 (p = 0.001) obtained from whole blood stored at 4 °C were statistically significant. Thus samples stored at 4 °C did not affect on DNA yield and quality..
Conclusion: We conclude that storage at 4 8C temperature for whole blood does not substantially affect the molecular assay measurements. This study enlightens the influence of storage temperatures and duration in genetic epidemiology.
