Opis:
In the present study, AISI 1020 plain carbon steel was surface alloyed with preplaced 50%Fe-10%W-40%B alloying powders using a tungsten-inert gas (TIG) heat source. Microstructure, hardness, and wear resistance of the surface alloyed layer were investigated. Following the surface alloying, conventional characterization techniques such as optical microscopy (OM), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), and X-ray diffraction analysis (XRD) were used to study the phase and microstructural examinations of the alloyed surfaces. Hardness measurements were performed across the alloyed zones, and wear properties of the alloyed surfaces were evaluated using a ball-on-disc wear test method. Hardness values of the phases formed in the alloyed layer are changing between 620±30 $HV_{0.1}$ and 2095±254 $HV_{0.1}$. The major phases formed in the surface alloyed layer were Fe₂B, FeB and FeW₂B₂. Wear test were realized against Alumina ball under the loads of 2.5 N, 5 N and 10 N at the sliding speed of 0.1 m/s for 250 m sliding distance. The friction coefficient of the 50%Fe-10%W-40%B alloyed steel surface is changing between 0.70 and 0.79 depending on applied loads. The wear rates of the surface alloyed steel ranged from $4.01 \times 10^{-5}$ mm³/m to $4.14 \times 10^{-4}$ mm³/m.

Opis:
Plant is one of the major forms of life on earth. It can produce its own food but cannot move about. Plants have well organized structures. They are beautiful and they determine local climates and are used as live fences. They phytoremediate and cool our environment. They provide us with oxygen, medicines, fuel, timber, recreation, industrial products; preservatives, pesticides in addition to all the three necessities of life: food, clothing and shelter. They purify the air and water bodies. It is therefore impossible to talk about life without plants because of their importance to the balance of nature. However, people have altered and often degraded their environment, though it has been taking place so gradually that its effects have not been drastically felt. Despite the enormous benefits of plants to humanity, they are disappearing at alarming rates. The reasons for this loss are many and include many anthropogenic activities. It is therefore quite imperative to ensure their effective conservation. This paper summarizes available information about the direct and the indirect benefits of plants and suggests some important measures to ensure their posterity. I hope, by bringing this information together, people will appreciate our plants and be frugal in using them.

Opis:
Home management of malaria involves presumptively treating febrile children at clinic or near home with antimalarial drugs distributed by trained members of the community provide medications and educate primary caregivers about treatment of malaria and recognition of severe illness. Structured questionnaires were administered to the parents, health workers and patent medicine vendors to determine acceptability of rectal artesunate and treatment seeking behaviours. Data obtained were analyzed using SPSS version 20 to assess association with p-value of < 0.05. Current first line antimalarial drug for treating childhood malaria at the PHCs was artesunate derivatives (90.3%) with no usage of chloroquine derivatives (0%) and common route of administration was intra-muscular (81.4%) with least usage of rectal (6.2%). Patent medicine vendors showed that the common drug derivatives purchase for treating childhood malaria was chloroquine derivatives (89.2%) with oral (91.9%) as most common route of administration and no awareness of rectal route (0%). Cases of resistance of malaria parasites to anti-malarial drugs, mostly chloroquine derivatives (89.3%) and least with artesunate derivatives (7.1%) observed by health workers. Incomplete dosage (95.6%) and fake drug (84.9%) were described as main factors responsible for malaria parasite resistance. Patent medicine vendors have come across cases of resistance of malaria parasites to anti-malarial drugs mostly chloroquine derivatives (93.2%) with drug abuse (89.2%) and fake drug (82.4%). Treatment of malaria is challenged by inadequate health-care infrastructure and community-based interventions.

Opis:
This paper examined the food security challenges vis-á-vis the paradox of increased domestic food production and food import in Nigeria. The study used time-series data from National Bureau of Statistic, Central Bank of Nigeria, Nigeria’s National Dailies and CIA Factbook reports. The trend analysis showed that the share of agriculture to the total Gross Domestic Product, GDP had a downward trend, especially from 1960-1979, where food import hovered around 2.92 % from 1960-74 and up to 9.85 % in 1975-79 of GDP. The result depicts an undulating trend in the contribution of agriculture and food import values to 2009 where food import rose astronomically from N2.6trillion (3.83 %) in 2005-2009 to about N20.6trillion (25.02 %) in 2010-2012. Results of the regression analysis confirmed that agriculture has a positive relationship with GDP, and contributes significantly with a coefficient of 0.852. The paradox however is that food import negates the a priori expectation as it is found to be positively related to the GDP: as food production increases marginally, food importation increases asymptotically. The paper recommends that reliance on food import could be minimized through increased budgetary allocation to the sector, and improvement in postharvest management practices that have hitherto, aggravated food insecurity in the country.

Opis:
Staphylococcus aureus is a very important human pathogen that generates a number of human infections. Isolation of vancomycin-resistant Staphylococcus aureus (VRSA) was carried out from wound samples of patients attending University of Uyo Teaching Hospital, Akwa Ibom state, Nigeria. A total of 45 wound samples from 15 patients were collected aseptically in triplicate, using sterile cotton swabs moistened in sterile normal saline. Microbiological analysis and susceptibility to vancomycin, including minimum inhibitory and minimum bactericidal concentrations (MIC and MBC), were carried out using standard methodologies. A total of 15 isolates were obtained and these showed varying MIC and MBC patterns. Out of the 15 S. aureus isolated, only one isolate had an MIC of approximately 4 µg/ml, while twelve isolates gave MIC values that ranged from 15.62 µg/ml to 250 µg/ml. The remaining 2 isolates gave MIC values that were ≥ 500 µg/ml. These 2 isolates exhibited alpha haemolysis on blood agar, unlike the others that were beta haemolytic. The results of the MBC also showed variations amongst the isolates. A total of 10 isolates gave MBC values that ranged from 62.5 µg/ml to 500 µg/ml, while the remaining 5 isolates gave MBC values that were ≥ 500 µg/ml. The high MIC and MBC values obtained showed that vancomycin-resistant Staphylococcus aureus is increasing at an alarming rate, and this accounts for the gradual decline in the effectiveness associated with the use of vancomycin. Given the widespread prevalence of VRSA, there is a need for newer therapeutics that can reverse this surge.

Klebsiella pneumoniae (KP) was investigated in respondents presenting signs and symptoms of urinary tract infection (UTI) in a rural community. Using simple random sampling, a total of 360 respondents (144 males and 216 females) were recruited into the study following informed consent and ethical approval. Mid-stream urine samples were collected from all the respondents aseptically using standard protocol. Isolation of K. pneumoniae was done using morphological characteristics and various biochemical tests while antibiotic sensitivity testing using various antibiotics was done using guidelines of Clinical and Laboratory Standard Institute. A total of 16 samples gave positive culture representing an overall prevalence of 4.4%. Furthermore, prevalence rates of 2.8%, 5.6%, 47.82%, 4.9%, 3.50%, and 8.60% for males, females, diabetics, in-patients, out-patients, and respondents above 60 years of age respectively were obtained. Resistance to antibiotics ranged from 37.50 to 56.25% for gentamycin and nalidixic, and tarivid, respectively. There is need for preventive measures aimed at sensitization of dwellers in community settings.

Opis:
The aim of this study was to investigate the impact of heat stress on production performance and oxidative stress in different plumage colors of Japanese quail. For this purpose, a total of 100 birds were used in this study. The 25 birds belonged to Wild-type (n=25, grey), Tuxedo (n=25, black), Golden (n=25, yellow) and Recessive white (n=25). The birds were reared for 42 days in an environmentally controlled room at 39°C and relative humidity of 60-65%. The body weight, body weight gain (g/bird/day), and feed conversion ratio were not different between the groups (p>0.05). However, the feed intake (g/bird/day) of the Wild-type had a higher value than the Tuxedo (black) group counterparts between 15 and 21 days different (p<0.05). There was no significant effect of heat stress on the carcass traits (p>0.05). Spleen weights were different between the groups (p<0.05). The yellow group had the highest spleen weight. The highest MDA level was found in the Recessive White variety, followed by Wild-type (grey), Golden (yellow) and Tuxedo (black), respectively. However, there were no statistical differences amongst the groups (p>0.05). There was also no statistical significance in glutathione (GSH) and superoxide dismutase (SOD) levels (p>0.05). The heat shock protein 70 kDa (HSP70) level was significantly different between the groups (p<0.001). The highest percentage was observed in the Golden (5.06%) and the lowest in the White (1.43%) variety. There was no superior color variety of Japanese quail regarding fattening performance and carcass traits. It is conceivable that when considering the stress response of the different colors, the Golden group is more sensitive to stress due to the hepatic and cellular level of HSP70.

Opis:
Bottom water flow in the layer with high permeability collector created by the radial drilling technology is considered. Dynamic of bottom water filtration to high permeability collector depending on properties of layer and layer fluid are investigated. Elaboration of mathematical model of fluid filtration in reservoir with high-permeability collector and calculations presents practical meaning for definition of radial drilling efficiency and estimation of flow rate to high permeability collector. Filtration of fluid in reservoir could be described with a model of cracked-porous medium by representing collector with high permeability as a crack. However for this model it is necessary to solve system of filtration equations in crack and porous block with satisfaction of conjugate condition on medium's division boundary. Problem formulation and solution is complicated for this model in case of two phase fluid filtration. Approach based on conception of interpenetrating continuums is simpler. In this case two phase fluid filtration in porous block with high permeability collector is described from a uniform position. Some numerical results of proposed generalized model of two phase fluid filtration from low permeability block to high permeability horizontal collector are implemented. Influence of reservoir anisotropy rate on well's waterbearing, bottom water breaking time and dynamic of water-oil surface development in oil saturated layer are studied.
W pracy rozważono przepływ wód dennych w złożu z silnie przepuszczanym kolektorem za pomocą wierceń radialnych. Przebadano zależność dynamiki procesu filtracji wód dennych wpływających do przepuszczalnego kolektora w zależności od właściwości warstw i płynów złożowych. Opracowanie matematycznego modelu filtracji płynu w zbiorniku z przepuszczalnym kolektorem oraz przeprowadzone obliczenia mają praktyczne znaczenie dla określenia skuteczności wierceń radialnych i oszacowania wydajności kolektora o dużej przepuszczalności. Filtrację płynu w złożu można opisać za pomocą modelu spękanego ośrodka porowatego, przedstawiając kolektor jako silnie przepuszczalne pęknięcie. Jednakże dla tego modelu konieczne jest rozwiązanie układu równań filtracji w porowatym i spękanym bloku, uwzględniając warunek granic podziału ośrodka. Sformułowanie i rozwiązanie problemu dla tego modelu jest skomplikowane dla przypadku filtracji płynu dwufazowego. Podejście oparte na koncepcji przenikających się kontinuów jest prostsze. W tym przypadku filtrację płynu dwufazowego w bloku z silnie przepuszczającym kolektorem opisuje się w sposób jednorodny. Zastosowano w praktyce niektóre wyniki numeryczne zaproponowanego uogólnionego modelu filtracji dwufazowego płynu z bloku o niskiej przepuszczalności do kolektora o wysokiej przepuszczalności. Przebadano wpływ anizotropii zbiornika na wodonośność otworu, czas przebicia wód dennych oraz dynamikę rozwoju powierzchni kontaktu woda-ropa naftowa w warstwie nasyconej ropą.

Opis:
Erthwork during rebuilding of the S3 route in Gorzów Wielkopolski exposed sediments of a palaeolake. The thickness of the sediment complex reaches 11 m. Two gyttja layers are separated by peats and fluvial sands and muds. The sequence reflects a multiphase development of the lake. Lacustrine sediments overlie Odranian (Saalian) (MOIS 6) glaciofluvial deposits and are covered by Vistulian glacial sediments (MOIS 2). At present, the stratigraphic position of the palaeolake is dated to the Eemian (MOIS 5e), with a probable continuation of the deposition into the early Vistulian (MOIS 5d-4). Rhinoceros bones (more than 100 pieces), including a skull with 24 well-preserved teeth, were discovered in the lower part of the palaeolake sediments. The preliminary expertise report, based mainly on the teeth analysis, allows assigning the rhinoceros remains into the genus Stephanorhinus. The finding of so many pieces of the skeleton of Stephanorhinus sp. in situ is unique on the scale of European scale. Apart from the rhinoceros remains, a single metacarpal bone of fallow deer (Dama dama) was found in the site. This is the first record of extant fallow deer in the Pleistocene of Poland. The palaeolake sediments were sampled and multidisciplinary research is planned to reconstruct the history of the development of this basin. The relationship between the rhinoceros andfallow deer remains with the palaeoenvironment will make it possible to ascertain the conditions in which those animals lived at higher latitudes during the Eemian Interglacial.

Resonant tunnelling via single impurities placed in a single barrier was experimentally studied. The typically observed structures in the current-voltage characteristics seem to be paired. Such a pair can be interpreted as ground and excited states of an impurity, related to X$\text{}_{xy}$ and X$\text{}_{z}$ valleys, which is in agreement with the results obtained for big mesas. However, it is not clear why X$\text{}_{xy}$ states can be seen without any phonon participation.

Opis:
The $K_{β} // K_{α}$ X-ray intensity ratios of Co, Ni, Cu and Zn in metalophthalocyanines complexes have been studied. Co, Ni, Cu and Zn elements have been excited by using 59.5 keV photons emitted by 50 mCi $\text{}^{241}Am$ radioactive source. K X-rays emitted by samples have been counted by a Si(Li) detector with resolution 0.16 keV at 5.9 keV. We have found that $K_{β} // K_{α}$ X-ray intensity ratios of Co, Ni, Zn, and Cu complexes have changed depending on chemical structures of Co, Ni, Zn and Cu. The measured values have been compared with the theoretical predictions and experimental values of pure elements.
