An Overview on Chemical Characterizations and Anti-Microbial Activities of Some Benzimidazole Derivatives
Full text linkBenzimidazoles are play an important role in medical field with so many pharmacological activities such as like anti-microbial, anti-viral, anti-diabetic, anti-cancer, antioxidant, anti-parasitic, antihelmintics, antiproliferative, anti-HIV, anticonvulsant, analgesic, antiinflammatory, antihypertensive, antineoplastic, proton pump inhibitor, antitrichinellosis  and other pharmacological activities. Benzimidazoles are remarkably effective compounds, extensive biochemical and pharmacological studies have confirmed that these molecules are effective against various strains of microorganisms. Different substituted benzimidazoles having anti-microbial activities. These activities encouraged the development of some more potent and significant compounds
Integrated Fungicidal Management for Downy Mildew of Pumpkin (Pseudoperonosporacubensis)
Full text linkDowny mildew of pumpkin is caused by the fungus (Pseudoperonosporacubensis), which is responsible for considerable damage to the cucurbits. This pathogen plays a major role for yield losses in pumpkin crop. Current study was intended to verify the effectiveness of different fungicides alone and in combination against downy mildew of pumpkin. Diseased samples were collected for inoculation from different farms of Okara district. A pumpkin variety (Mahadeev) was inoculated by spraying method grown at experimental area of the Department of Plant Pathology, University of Agriculture, Faisalabad under randomized complete block design (RCBD). Selected chemotherapeutic mixtures were sprayed for the control of (Pseudoperonasporacubensis) under field condition. The data were recorded and analyzed statistically. Ipovalicarb (s) + Propanib (P) revealed maximum efficacy against disease (60%) followed by Tebuconazole (s) + Metiram (p) (58%) and Matlaxyal (s) + Mancozeb (p) (55%), Cymoxinal (s) + Mancozeb (p) (52%), Difenconazole (s) +Mancozeb (p) (46%) and Chlorothalonil (p) + Fosytyle Al (39%) respectively. Thus, Ipovalicarb (s) + Propanib (P) can be used to manage the disease under field conditions

Ecological perception of fish farmers in Yenagoa Metropolis, Nigeria
Full text linkThe environment plays a keystone role as a hub for biotic and abiotic interaction. Ecological interactions (positive or negative) are reflection of the environmental status quo. Some human activities have grossly infringe on vital components of the ecosystem. A total of 100 questionnaires were administered to fish farmers in Yenagoa metropolis, Nigeria and 80% were retrieved (55% male and 45% female). Furthermore, about 62.50 – 77.50% is with the opinion that temperature, flooding rate, precipitation and pollutants depositions have increased and wind pattern getting warmer, while 43.75 – 52.50% responded that there is change in spawning time, decrease in fish production and juvenile availability, extinction and presence of invasive species. The study confirm the need to adopt multifaceted approaches in sustaining our ecosystem in order to mitigate adverse effects as well as ensure the bioavalability of keystone species
CHARACTERIZATION OF THE FITTING CLASS OF SUBGROUPS OF FINITE GROUPS AND APPLICATIONS TO ALGEBRAIC REPRESENTATION THEORY
Full text linkIn this paper we present new results on properties of finite subgroups and their applications to algebraic representation theory and group theory in general. In particular we give results on fittings
Solid State Synthesis of LiNiO2
Full text linkBimetallic oxide nanomaterials are synthesized by solid state combustion route integrates the synthetic chemistry. Simply, burning of two metal oxides in presence of polymer fuel for its bimetallic oxide nanomaterials. Nanosized lithium niobate material is prepared by self-propagating combustion methods using polymer as a fuel. Lithium oxide and nickel oxide with polyvinyl alcohol was ignited in an open atmosphere for few minutes to form lithium niobate residue. As prepared lithium niobate sample was well characterized for its structure by employing powder X-ray diffraction (XRD) tool. The morphology of as prepared lithium niobate material was studied by Scanning Electron Micrograph (SEM) tool. Fourier Transform infrared (FTIR) spectral study was undertaken to know the bonding in the prepared bimetallic oxide sample
Tidal Energy: advantage and disadvantage
Full text linkMarine current energy is one of the most exciting emerging forms of renewable energy. Tidal energy is produced through the use of tidal energy generators. Large underwater turbines are placed in areas with high tidal movements, and are designed to capture the kinetic motion of the ebbing and surging of ocean tides in order to produce electricity. Tidal power has great potential for future power and electricity generation because of the massive size of the oceans. Tidal energy is a form of hydropower that converts the energy of the tides into electricity or other useful forms of power. The tide is created by the gravitational effect of the sun and the moon on the earth causing cyclical movement of the seas. Tidal energy is therefore an entirely predictable form of renewable energy
The external learning and management innovation: evidence from China
Full text linkBuilding on organizational learning and management innovation theories, this study examines how firms in emerging economies realize management innovation. The relationship between external learning and management innovation is investigated. The propositions that market exploratory and exploitative learning both have a positive effect on the management innovation are proposed. The paper contributes to organizational learning and management innovation theories by explaining through external learning how firms in emerging economies realize management innovation
Assessment of diarrheal diseases among children under the age of five and its impacts in health sciences
Full text linkDiarrheal disease is a leading cause of child mortality and mobility in the world and mostly results from contaminated food and water sources. From WHO, 780 Million individuals worldwide lack access to improved drinking water and 2.5 million lack improved sanitation. Diarrhea due to infection is widespread throughout developing countries. In developing countries, children under 3 years old experience an average three episodes of diarrhea every year. Each episode deprives the child of the nutrition necessary for growth hence as a result; diarrhea is a major case of malnutrition. This study therefore intended to determine the causes, control measures and management of diarrheal diseases in North Kamagak Location, Rachuonyo South Sub-County, Kenya. The objectives of the study were to: determine the causes of diarrheal diseases among the under five in the location; find out intervention strategies during diarrheal diseases outbreak among the residents; establish treatment options for diarrhea among the under fives; and identify home management practices of under fives diarrhea in the rural communities. The population of the study involved all under five children in North Kamagak location. Descriptive research design has been used. Stratified random sampling has been used to select 20 households from each of the three sub-locations in the location. Purposive sampling has been used to select 2 children from each selected household. Collected data has been analyzed using descriptive statistics and results presented in terms of tables, charts and graphs. The results obtained from this study show that using dirty water and not washing hands are the major causes of diarrhea. Results are useful to the ministry of health and the public in general in prevention and management of diarrheal diseases
The lack of sensitivity of methicillin resistant Staphylococcus aureus (MRSA) toward teicoplanin
Full text linkA total of 60 methicillin resistant Staphylococcus aureus (MRSA) strains clinical samples in children were collected from cellulitis, abscess, and wound samples in Al-Hilla, and Babylon teaching hospital was identified to species level and antibiotic susceptibility testing with a VITEK-2 system. In the present study, 24 (40%) of MRSA isolates were community- acquired methicillin resistant Staphylococcus aureus (CA-MRSA), and 36 (60%) were hospitalized-acquired methicillin resistant Staphylococcus aureus (HA-MRSA). The results showed that 35 of female, and 25 of male of MRSA isolates, and these isolates were taken from 7 of infants aged less than 6 months, and 53 children aged between 6 months and 4 years of MRSA isolates. In the present study, antimicrobial susceptibility testing with the VITEK 2 system gave resistant to 10 and sensitive to 6 antibiotics to all bacterial isolates, but only 3(5%) of bacterial isolates were resistant to teicoplanin
