Background: Modern restorative dentistry offers many methods of restoring the carious teeth. The advancements in adhesive dentistry have brought significant changes in the treatment of caries. Dental composite formulations have been continuously evolving ever since BISGMA was introduced to dentistry by Boven in 1962. The composite materials can be divided into direct and indirect resin composites (IRC). Indirect composite restorations are usually recommended in posterior teeth requiring large restorations.

The study aims to effects of Land Use/Land Cover Changes (LU/LCC) is the quantitative method, to expound the impact of land use/land cover changes in Ambuliyar watershed, Tamilnadu, India. The relationship between Land Use Changes and its trend is analyzed using IRS LISS III data. Further, the preparation of LU/LC map using Survey of India (SOI) Toposheet for the year of 1972 has come in handy to know the past land use pattern.

This research was conducted to study the effects of project-based learning approach in terms of students' engagement in classroom of Information Communication Technology (ICTs). The study involved two sets of the modules, namely project-based learning with scaffolding and existing approaches. Both modules are used as a guide in the implementation of the project for the Computer Hardware topic. The study was based on a quasi-experimental approach using nonequivalent control groups design to evaluate the effectiveness of teaching approaches on students’ engagement.

In order to understand the photosynthetic physiological characteristics of Davidia involucrata, using portable LI-6400 photosynthesis Davidia involucrata measured net photosynthetic rate ( Pn), stomatal conductance (Gs), CO2 concentration between cells (Ci) and transpiration rate (Tr).

There has been a decline in the textile industry of Ghana in recent years. This is attributed largely to the growing competition posed by imported products. This competition affects the entire industry with the traditional sub sector being no exception.

Character association and component analysis at genotypic level were studied in mutagenised populations (M2) of grasspea land race “Dhenkanal local” following seed treatment with gamma-rays, EMS, NG and their combinations. Seeds/plant emerged as an independent direct yield contributing trait in all treatments except 40kR gamma-rays + 0.2% EMS. In general, number of branches/plant, pods/plant and seeds/plant exhibited very high and significant positive association with seed yield/plant.

Pressure ulceration of the skin is a pervasive problem in health care. The cost of the problem is enormous, both in terms of individual human suffering and in terms of the financial expenses to society. Approximately 60,000 people a year die from complications of pressure ulcers. The epidemiology reveals at least three major at risk groups: (1) the young neurologically impaired patient, (2) the elderly patient, (3) the hospitalized patient. Healthy and mobile individuals make numerous postural adjustments throughout the day to prevent pressure sores from ever developing.

Objective: Retrospective assessment of response rate, clinical outcome and toxicity in head and neck cancer patients treated with induction chemotherapy followed by concomitant chemo radiotherapy. Patients and Methods: From April 2011 till March 2014, we collected the data for patients with locally advanced head and neck cancer who were treatment with 3 cycles of induction chemotherapy using cisplatin and fluorouracil (5-FU), (PF) followed by radiation therapy for a total radiation dose of 66 Gy and concomitant cisplatin at a dose of 100 mg/m2 on days 1, 22, and 43 of radiotherapy.

This study discusses the changing role of government in commercial activities in Kenya since the colonial era. The focus is whether the state played a minimal or greater in commercial activities and the instruments used to achieve the desired role. The study traces and discusses historical events, theories, studies, policies, and institutions used by government to achieve the desirable role. The study is divided into four phases and the findings show that during the colonial era, the state played a major role in commercial activities driven by an expansionist policy.

Many environmental factors, biotic and abiotic interact to influence the organismal development. Organisms respond to environmental stresses with behavioral, physiological or morphological adjustment to counter its effects and maintain normal functioning. In the present study, the high parental density results in offspring with smaller body size compared to offspring from parents that reproduced at lower densities.
