Opis:
The net radiation over vegetated surfaces is one of the major input variables in many models of soil evaporation, evapotranspiration as well as leaf wetness duration. In the literature there are relatively few studies on net radiation over sugarcane crop in tropical climates. The main objective of the present study was to assess the solar radiation components measured and modelled for two crop stages of a sugarcane crop in the region of Rio Largo, Alagoas, North-eastern Brazil. The measurements of the radiation components were made with a net radiometer during the dry and rainy seasons and two models were used to estimate net radiation: the Ortega-Farias model and the Monteith and Unsworth model. The highest values of net radiation were observed at the crop development stage, due mainly to the high indices of incoming solar radiation. The daily average albedos of sugarcane at the crop development and mid-season stages were 0.16 and 0.20, respectively. Both models showed a better fit for the crop development stage than for the mid-season stage. When they were inter-compared, Monteith and Unsworth model was more efficient than Ortega-Farias model, despite the dispersion of their simulated radiation components which was similar.

Opis:
A field experiment was conducted at Landmark University Omu-Aran, Nigeria from June to November 2017 and repeated at the same time in the year 2018 on a nematode infested soil to evaluate the effects of different amounts of Siam weed compost on the performance of root-knot nematode (RKN) infested tomato. The compost was applied a week before planting as soil amendment at the amount of 0.0, 0.5, 1.5, and 2.0 t·ha-1, while carbofuran was applied at the rate of 3.0 kg·ha-1. Four weeks old tomato seedlings cultivar ‘Roma VF’, which is susceptible to RKN, was transplanted to already prepared soil. Results of the experiment showed that the compost, especially in the amount 2 t·ha-1 and carbofuran at 3 kg·ha-1, brought about significant reduction of the population of RKN in soil and roots, and a significant increase in the growth and yield of tomato. The result of the experiment showed that Siam compost can be used for the managing root-knot nematodes in tomato cultivation, as an environmentally safe factor.

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.

Zainteresowanie ziarnem pszenżyta jako surowcem dla przemysłu fermentacyjnego uwarunkowane jest zawartością skrobi i wysoką aktywnością amylolityczną. Początkowo badania prowadzono w celu wykorzystania ziarna jako słodu piwowarskiego i gorzelniczego. Uzyskane rezultaty nie potwierdziły możliwości szerszego zastosowania tego ziarna w przemyśle. Wykorzystanie pszenżyta do produkcji energii odnawialnej w postaci bioetanolu stwarza wymierne korzyści dla rolnictwa i ekologii. Prowadzone są również prace hodowlane zmierzające do uzyskania nowych odmian o wyższej wydajności bioetanolu.
Interest in triticale grain as raw material for fermentation industry is subject to a high content of starch and amylolytic activity. Initially, the study was carried out in order to use the grain as beer and malt distillers. The results obtained were not, however, wider application in industry. Triticale new opportunities for renewable energy production in the form of bioethanol create tangible benefits for agriculture and ecology. Work is also the breeding efforts to obtain new varieties with higher yields of bioethanol.

Background. Obesity and a sedentary way of life play an important part in public health in Hungary. This phenomenon is becoming more and more serious not only in adults but also children. Adults’ health behaviour is greatly affected by the existence or absence of health awareness. Regular exercising in association with general fitness form an integral part of health awareness. Our objective is to demonstrate the nutrition and fitness status of students in higher education with a comprehensive test. Material and methods. Beside general factors affecting health, such as BMI, skeletal muscle, body fat, visceral fat percentage, participants performed practical tasks which provided data of their stamina, muscular strength and fitness status: (1) a 15/20-minute shuttle run, (2) a scheduled abdominal muscle test (3) manual clamping force measurement (4) a scheduled push up test (5) a standing long-jump test, and (6) a flexibility test. Results. According to our survey, young adults’ nutrition status was satisfactory, two third of them had normal BMI. Left manual clamping force and trunk stretching force in men, stamina and explosive power in women were significantly determined by BMI classification. Basing on these results, we can state that body weight has no effect on joint mobility. Conclusions. The present study draws attention to several former conclusions which suggest that more efforts are needed in higher education to improve health promotion of the youth. Introduction of compulsory physical education classes might facilitate further research which may follow-up the changes in the fitness status of young people.
Wprowadzenie. Otyłość i siedzący tryb życia stanowią ważną aspekt zdrowia publicznego na Węgrzech. Zjawisko to staje się coraz poważniejszym problemem nie tylko wśród dorosłych, ale i wśród dzieci. W istotnym stopniu wpływa na to zachowanie zdrowotne osób dorosłych, które charakteryzuje niska świadomość zdrowotna. Regularne ćwiczenia w połączeniu z ogólnymi formami fitness stanowią integralną część świadomości zdrowotnej. Naszym celem jest wykazanie stanu odżywienia i sprawności studentów szkół wyższych poprzez kompleksowy system testowy. Materiał i metody. Oprócz ogólnych czynników wpływających na zdrowie, takich jak BMI, mięśnie szkieletowe, tkanki tłuszczowej, tkanki tłuszczowej, uczestnicy wykonali zadania, które dostarczyły danych o ich wytrzymałości, sile mięśni, stanie sprawności: (1) 15/20-minutowy bieg (2) test mięśni brzucha (3) ręczny pomiar siły nacisku (4) test naciskowy (5) test długiego skoku (6) test elastyczności. Wyniki. Naszym zdaniem, poziom odżywiania młodych ludzi był zadowalający, dwie trzecie z nich miało normalne wskaźniki BMI. Siła zaciskowa lewej ręki i siła rozciągania tułowia u mężczyzn, wytrzymałość i siła wykopu u kobiet w znacznym stopniu pokrywały się ze wskaźnikami klasyfikacji BMI. Możemy zatem wnioskować, że masa ciała nie wpływa na ogólną mobilność. Wnioski. Niniejsze badanie potwierdzają wyniki naszych wcześniejszych badań, co może sugerować, że potrzebne są większe wysiłki na rzecz poprawy promocji zdrowia młodzieży w szkolnictwie wyższym. Wprowadzenie obowiązkowych zajęć wychowania fizycznego mogłoby pomóc w dalszych badaniach, które z kolei mogą prześledzić zmiany w stanie umiejętności sprawnościowych młodych ludzi.

Opis:
The geological and structural evolution assessment of the Basement Complex rocks in Iwaraja area, southwestern Nigeria showed that the basement rocks comprise quartzites and quartzschists of the Effon Psammite Formation, quartz-mica schists, biotite schists, migmatitic gneisses, granitic gneisses, late and post-tectonic granitic rocks including pegmatites, which have been subjected to two phases of deformation. The first phase is mainly a fabric forming deformation that also led to the development of moderately plunging mineral lineation. No minor fold of this phase was recognized. The second deformation phase gave rise to the development of Iwaraja (ductile) shear zone. The mylonitic foliation is sub-vertical and steeply dipping and while the mineral lineation is sub-horizontal and shallowly plunging. Within granitic gneiss mylonites, the shear zone is characterised by early and late open to tight folds of pegmatite dykes. Adjacent the shear zone, ptygmatic folds of quartzo-feldspathic veins in gneisses and crenulated cleavages that overprinted earlier schistosity surfaces in the quartz-mica schist also characterised this deformation phase. Extensional fractures in the various lithologies generally show bimodal orientations mainly in the WNW-ESE and NW-SE directions, which are nearly perpendicular to the regional metamorphic foliations. These deformation conditions depict structural features that are associated with internal zones of orogenic belts. Within the study area, the structures document late-Precambrian deformation during the closing stages of Pan-African orogenesis.

Opis:
For years now, the continual degradation of soils in the tropics, and around the globe has continued to be one of the challenges facing humankind. Soil erosion is one of the factors gearing low food production, environmental pollution and degradation, acting like an hindrance towards the realization of the Sustainable Development Goals (SDGs) two (zero hunger) including SDG six (clean water and sanitation). The importance of saturated hydraulic conductivity (Ks) of a soil to Agriculturist, Environmentalist including Engineers cannot be exhausted, as this single hydro-physical soil property controls many processes in the soil system. An experiment was conducted to access the vulnerability of University of Abuja soils to erosion. Result of data analysis proves that the saturated hydraulic conductivity of the soils is slow to extremely slow with value recorded at (0.89 – 4.50 mm hr-1). Field data outcome presents a view that the soils of the area is mostly very compact to compact, with porosity value ranging from (1 – 21%). Saturated hydraulic conductivity estimation was done using hydro-physical models. The performance of the models were evaluated using Root Mean Square Error (RMSE) statistics. Outcome of the model comparation proves the two model as been able to effectively estimate the water flux of the area, presenting RMSE values at (5.67 and 2.41 respectively for the two models). The study thus concluded that for loss of arable land to be minimized or avoided and for environmental sustainability, ecological tool like planting of grasses including trees can be employed to salvage the impending case of soil erosion in the area.

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:
Porous superhydrophobic layer of low-density polyethylene (LDPE) was created by a simple approach on the Poly(vinylidenefluoride) (PVDF) hollow fiber membranes. Acetone and ethanol mixtures with different volume ratios were used as the non-solvent on the coating surface. A 5:1 (v/v) acetone/ethanol ratio provided a porous surface with a 152° ± 3.2 water contact angle. The high contact angle could reduce membrane wettability for better carbon dioxide capture when the membrane was used as gas-liquid contactor in absorption processes. To assess the effect of the created superhydrophobic layer, the pristine and modified membranes were tested in a CO2 absorption system for ten days. The results revealed that the absorption flux in the modified membrane was higher than that of pristine membrane.

Opis:
Understanding a membrane’s morphology is important for controlling its final performance during protein immobilization. Porous, symmetric membranes were prepared from a polyvinylidene fluoride/N-methyl-2-pyrrolidinone solution by phase inversion process, to obtain membrane with various microsized pores. The concentration and surface area of aprotein dotted on the membrane surface were measured by staining with Ponceau S dye. The dotted protein was further scanned and analysed to perform quantitative measurements for relative comparison. The intensity of the red protein spot and its surface area varied depending on the membrane pore size, demonstrating the dependence of protein immobilization on this factor. The membrane with the smallest pore size (M3) showed the highest protein spot intensity and surface area when examined at different protein concentrations. An increase in the applied protein volume showed a linearity proportional trend to the total surface area, and an uneven round dot shape was observed at a large applied volume of protein solution.

Opis:
In OFDM systems, peak-to-average power ratio (PAPR) reduction of the signal is one of the main challenges that need to be overcome in order to use the transmitter in an efficient manner. As one of attractive techniques, interleaving can be used in PAPR reduction for multicarrier signals without spectrum distortion. In this paper, the authors propose to extend the possibilities of interleaving to improve PAPR reduction, to use a new coding of interleaver keys at the transmitter and a robust decoding procedure at the receiver. In order not to degrade the data rate, the use of null subcarriers to transmit side information to the receiver is proposed and evaluated. Simulation results in the context of the WLAN 802.11a standard in the presence of a nonlinear power amplifier model with memory, show a reduction of PAPR of approximately 5.2 dB, and an improvement of bit error rate and error vector magnitude of about 2 decades and 4% respectively, while respecting the spectral mask specification.
