Semigroups Of Linear Operators And Application To Differential Equations

This work concerns one of the most important tools to solve well-posed problems in the theory of evolution equations (e.g diusion equation, wave equations, ...) and in the theory of stochastic process, namely the semigroups of linear operators with application to dierential equations.

Studies On Yersiniosis In Human And Selected Animal Populations In Jos And Its Environs

ABSTRACTYersinia enterocolitica and Yersinia pseudotuberculosis are important food and water borne pathogens that has recently emerged world wide. This study was aimed at characterizing the prevalence of Yersinia enterocolitica and Yersinia pseudotuberculosis in human and selected animal populations in Jos and its environment. Three thousand stool samples from human and selected animal species from 5 different locations in Jos and its environs were surveyed over a period of three years. Human...

Epidemological Studies on Some Microbial And Parasitic Infectious of Nomadic Fulani Herdsmen in Ebonyi State, Nigeria

Abstract Over the years, nomadic Fulani herdsmen have established different settlement camps outside the traditional villages of their indigenous host communities in Ebonyi State. With increasing concerns about the health condition of the nomads, this study was undertaken to investigate the prevalence and distribution of some microbial and parasitic infections amongst the spartially distributed population of the nomadic Fulani herdsmen in Ebonyi State. This investigation was carried out...

Spray Distribution In A Tree Crop

Mature apple trees were sprayed using a Knapsack mistblower fitted with 3 different nozzle systems, one of which provided an induced electrostatic charge on the spray droplets. Spray distribution was assessed by examining fluorescent tracer deposits on Kromekote cards which had been positioned in different parts of the tree canopy. Subsequently, bioassays with codling moth (neonate larvae) and formulations of cypermethrin examined the biological effect of deposits. Small uncharged drop...

STUDIES ON BOVINE COCCIDIA [APICOMPLEXIA: EIMERIIDAE] IN PARTS OF PLATEAU STATE, NIGERIA

A parasitological examination of 2,500 faecal samples of cattle was carried out in Plateau State, Nigeria, to determine prevalence, seasonal distribution and sources of various species of Eimeria in both sexes, age groups, breeds and husbandry systems. Effects of temperatures on sporulation of Eimeria oocysts and chemical analysis of the Eimeria oocysts were also determined. Out of 2500 samples examined, 1567 i.e 62.68% were positive for twelve species of Eimeria...

HUMAN METAPNEUMOVIRUS AND RESPIRATORY SYNCYTIAL VIRUSES IN GHANAIAN CHILDREN BELOW FIVE YEARS WITH ACUTE LOWER RESPIRATORY TRACT INFECTIONS IN ACCRA, GHANA

ABSTRACT Acute lower respiratory tract infection (ALRTI) in children under five years is predominantly cause by Respiratory syncytial virus (RSV) but in recent times Human Metapneumovirus (HMPV) has also been implicated in ALRTI. In Ghana, the few studies on ALRTI have focused on the prevalence of RSV and the viral etiological agents causing acute bronchiolitis, bronchopneumonia and pneumonia. This cross sectional study sought to detect, characterize and genotype respiratory syncy...

PLASMID PROFILING OF MULTIDRUG RESISTANCE CLINICAL ISOLATES OF (Pseudomonas aeruginosa)

ABSTRACT The emergence of multiple antibiotic resistance in bacteria and the indiscriminate use of antibiotics contribute to the dissemination of resistant pathogens in the environment which may cause problems in therapy and is a serious public health issue. This study was conducted to determine the incidence of Pseudomonas aeruginosa in clinical samples and their antibiotics resistant pattern. The organisms were isolated using standard microbiological techniques and the ant...

In Vitro Antibacterial Activity and Toxicity Study of Eucalyptus Camaldulensis Leaves Extracts against Clinical Isolates of Salmonella Sp

ABSTRACTEucalyptus camaldulensis is an important medicinal herb in traditional healthcare practice and has been reported for various biological activities. The objective of the present study was to analyze the antibacterial potentials and toxicity study of E. camaldulensis leave extracts against clinical isolates of salmonella species. The E. camaldulensis leaves were extracted separately and successively with ethanol, water and methanol using percolation method. The extracts were tested in v...

Isolation and Characterization of bateria from Panteka stream, kaduna, Nigeria and their potential for bioremediation

ABSTRACT Panteka stream is a flowing stream polluted with waste from the activities of mechanics. Water samples collected at different sampling points of the stream were analysed in order to determine the level of heavy metal contamination and bacteria diversity with the view to elucidating the bioremediation potentials of the bacteria isolates. Four bacteria species with high tolerance to lead, zinc, iron, nickel and cadmium were identified by morphological and biochemical analysis as ...
