Rizwan Ashraf, Bushra Sultana, Sadaf Yaqoob and Munawar Iqbal. Allelochemicals and crop management: A review. Current Science Perspectives 3(1) (2017) 1-12

Abstract

The allelochemicals have diverse applications in agriculture, especially in weed management in crop systems as growth regulator, weed maganement and as pesticides etc. In allelopathy bioactive compounds are employed for growth regulation, weed infestation control and pest management and are safer than synthetic chemicals and their use preclude the health defects and environmental pollution of synthetic chemicals. Most of the studies asserted the inhibitory action of allelochemicals as well explored known dimension of allelopathy on the weed and pest management with the use of allelochemicals. In this study, the applications of allelochemicals for weed management for different crops as well as types and methods are reviewed. Moreover, mode of action and effect on soil properties, plant composition, photosynthesis, water uptake and limitation are highlighted.

Assessment of the antimicrobial and antioxidant activities of the extracts of Garcinia kola, Garcinia epunctata and Acacia kamerunensis plants used for oral hygiene in Ghana. Current Science Perspectives 3(1) (2017) 13-20

Abstract

Chewing sticks and chewing sponges derived from plants stems and twigs are commonly used alone or in combination with conventional brushing for routine dental hygiene in Ghana. To examine whether phytochemical attenuation of microbial growth and radical scavenging activities accounts for observed dental hygiene efficacy, methanol  and water  extracts  of  three plant  species  used  traditionally  for the preparation of chewing sticks (Garcinia kola and Garcinia epunctata) and for the preparation of chewing sponge (Acacia kamerunensis) were assessed for their antimicrobial and antioxidant activities in vitro. Phytochemical analysis revealed the presence of saponins in all plant extracts. With the exception of the water extract of Acacia kamerunensis that failed to inhibit the growth of E. faecalis and K. pneumonaie in broth dilution assays, all other extracts exhibited positive inhibitory activity against all the test microorganisms. Microbial growth inhibition efficacy varied but were lower than that of the standard drugs (Ciprofloxacin-antibacterial and Fluconazole-antifungal) and that of conventional mouthwash (Chlorhexidine). Extracts showed varied concentration dependent 2, 2’-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity with IC50 values that were significantly lower than that of Ascorbic acid. The results imply that locally used chewing stick and chewing sponges derived from the test plants have constituents that inhibits microbial growth in vitro and that also exhibits antioxidant activities in vitro.

Abstract

An overview of diverse feasible strategies for heating and cooling in homes are discussed on this paper. The thermal performance of various sorts of systems like PCM trombe wall, PCM wallboards, PCM shutters, PCM constructing blocks, air-primarily based heating structures, ground heating, ceiling boards, and so forth, is provided on this paper. All systems have true potential for heating and cooling in constructing via phase trade materials and additionally very beneficial to lessen the power demand of the homes. There are huge numbers of PCMs that melt and solidify at a wide variety of temperatures, making them attractive in some of packages. This paper additionally summarizes the research and analysis of the thermal electricity garage structures incorporating PCMs to be used in specific packages.

Abstract

Despite the availability of multiple medical therapies for the treatment of heart failure, quality of life is often poor for the majority of patients, and the mortality remains high. The treatment is regularly not well tolerated and frequent hospitalized for some patients. This reviews study the management and treatment of various heart diseases.

Abstract

An investigation trial was done at Agriculture Research Station, South Baghdad, Iraq, amid the two progressive periods of 2012 and 2013 to consider the impact of effective microorganisms (EM) at 5% on Barley, Corn and Chard, from the acquired results demonstrated that it is desirable over include EM at 5% as a dirt application isolated into one measurements connected at three times a season to improve synthetic properties of soil, biomass yield, and fiery debris, seed minerals substance of plants.
