Influences of nitrogen and potassium fertilizer rates on pepper and tomato yield and nutrient uptake under field conditions

    The influence of nitrogen (N) and potassium (K) fertilizers on pepper (Capsicum annuum L.) and tomato (Lycopersicon esculentum Mill) growth, fruit production and nutrient uptake was determined under field conditions for two successive years. The aim of the experiment was to determine the optimum N and K fertilizer rate for yield and quality parameters. Experiments were...

Influences of rosuvastatin on the expression of matrix metallopeptidase 9 (MMP-9) through extracellular-signal-regulated kinases (ERK) pathway in mononuclear cell line (THP-1) derived macrophages induced by oxidized low density lipoprotein

    The current study aims to probe the changes in matrix metallopeptidase 9 (MMP-9)expression during differentiation as the mononuclear cell line THP-1 is converted into foam cells, as well as the underlying influence and mechanism of rosuvastatin.PMA was used to induce THP-1 cells transform into macrophages and treated with various concentrations, whereas...

Homotopy analysis method for Zakharov-Kuznetsov (ZK) equation with fully nonlinear dispersion

    In this paper, we apply Homotopy Analysis Method (MHAM) to find appropriate solutions of Zakharov-Kuznetsov (ZK) equations. Numerical results coupled with graphical representation explicitly reveal the complete reliability of the proposed algorithm. Key words: Homotopy analysis method, Zakharov-Kuznetsov (ZK) equation, exact solutions,...

Management of vegetal covers on Pecan tree with fertilizer irrigation

    The pecan Carya illinoinensis (Wangeh.) K. Koch is a fruit tree in domestication process, and the components of its profitable and sustainable management are continuously generated by research (Wood, 1991, 2006). For the soil management, the plants that grow on it are traditionally cataloged under the “weed” concept, which states that they must be...

Surveillance of the condition of bacteria and Amaranthus viridis in a gasoline contaminated soil

  The condition of bacteria and Amaranthus viridis in gasoline-contaminated soil was surveyed. The soil was treated with different concentrations of petrol oil: 0 ml (control), 18, 56, 112, 168 and 224 ml. Each of the concentrations was in triplicates. Seventeen (17) bacterial isolates were recovered from the control soil while twenty (20) bacterial isolates were recovered from the...

Design of an HIV drug resistant patient management system in a digitally connected world

    It is inevitable that drug resistance will become of concern in the treatment of HIV/AIDS infected patients due to the fact that the virus mutates at a high speed, selective pressure and patients that default from treatment. Not only is the management of HIV drug resistant patients difficult, but so too is the management of the patients’ data. The use of information...

First report of Tuber macrosporum occurrence in Poland

    Tuber macrosporum, a large spore species is first time confirmed from Poland. It grows naturally in southern part of Poland, in calcareous soils. The fruit bodies of the species were found in mixed fresh forest with dominant tree species such as:Pinus sylvestris, Carpinus betulus and Quercus robur. The soil chemistry and texture of the site was analysed. Fruit...

Evaluation of crayfish chaff charcoal agar as a transport medium for anaerobes

    A laboratory formulated crayfish chaff charcoal agar (CCCA) was evaluated both as transport and storage medium for anaerobic bacteria in parallel with Amies charcoal agar (ACA), cooked meat medium (CMM) and thioglycollate broth (TCB). The survival of anaerobes in swab obtained clinical specimens and viability of specific anaerobes in these media were assessed. Eight genera of...

Monitoring the temperature of the milling process using infrared camera

    The study of temperatures generated in machining processes has been the theme of research since the beginning of the XX century. High temperatures can provoke changes in the microstructure of materials, resulting in form errors that may cause loss of the machined material and a decrease of tool life. As a result, high temperatures can be responsible an increase in...
