A non-renewable fuel like petroleum has been used from centuries and its usage has kept on increasing day by day. This also contributes to increased production of greenhouse gases contributing towards global issues like global warming. In order to meet environmental and economic sustainability, renewable, carbon neutral transport fuels are necessary. To meet these demands microalgae are one of the key sources for the production of biodiesel. These green microalgae synthesise lipids by using sunlight like plants do but in a much more efficient manner. Biodiesel provides more environmental benefits, and being a renewable resource it has gained lot of attraction. However, the main obstacle for commercialization of biodiesel is its cost and feasibility. Biodiesel is usually used by blending with petro diesel, but it can also be used in pure form. Biodiesel is a sustainable fuel, as it is available throughout the year and can run any engine. It will satisfy the needs of the future generation to come. It will meet the demands of the future generation to come.

This article analyzes the influence of the prophet Siner Van Rensburg and later interpreters of his visions on creation of the Boer and Afrikaner national identity in the Republic of South Africa from the start of the 20th century until today. The work of the prophet and his disciples is viewed in the light of important historical events and contemporary political circumstances. Through the interpretation of the political instrumentalization of this prophecy, the mechanism of the making of and functioning of political foresight is demonstrated. This is also applicable to the opus of numerous other seers all over the world. A critical overview of important works of authors dealing with this issue is given, as well as a theoretical basis for planned future research. The primary role of the prophecy is, inthis paper, not identified as the divination of future events but as the ideological reinterpretation of the past and the present through the prism of determinism and facing social change in times of crisis, as well as their negation. Thus, the supposed prophecies become an acceptable place to express socially unacceptable attitudes and unrealized political wishes, goals and ambitions.

Nimesulide belongs to the group of semi-selective COX-2 inhibitors, widely used in solid oral formulations. In the present work the influence of surfactants among other drug excipients, as well as particle size of the active substance and the effects of medium pH on the dissolution rate of nimesulide from solid pharmaceutical forms. For that purpose, four different preparations containing 100 mg nimesulide per tablet and available in the market of Bosnia and Herzegovina (labeled here as A, B, C and D) were studied. The test for the assessment of dissolution profiles of the formulations was performed in surfactant-free dissolution medium pH 7.5. The dissolution profiles were compared by calculating difference (f1), and similarity (f2) factors. The increasing dissolution medium pH value from 7.5 to 7.75 resulted in a significant increase of nimesulide dissolution rate from the examined formulations. Also, the results showed that particle size affects to a great extent the dissolution rate and the best results were achieved with micronized nimesulide. The presence of the surfactants among the other excipients expressed a negligible effect on the dissolution profile.

Liver injuries caused by high voltage electricity are rare and result in high mortality and morbidity. They are produced by the resistance to the passage of electrical current through the tissue, which creates heat that leads to coagulation necrosis and rupture of the cell membrane. We present a case of an electrical injury to the liver, diagnosed by ultrasound and CT in a 39-year-old man who presented with skin burns on his right hand and right hemiabdomen. Injuries occurred after the contact with 220 kV high voltage electricity.

In recent years, formidable effort has been devoted to exploring the potential of Resistive RAM (RRAM) devices to model key features of biological synapses. This is done to strengthen the link between neuro-computing architectures and neuroscience, bearing in mind the extremely low power consumption and immense parallelism of biological systems. Here we demonstrate the feasibility of using the RRAM cell to go further and to model aspects of the electrical activity of the neuron. We focus on the specific operational procedures required for the generation of controlled voltage transients, which resemble spike-like responses. Further, we demonstrate that RRAM devices are capable of integrating input current pulses over time to produce thresholded voltage transients. We show that the frequency of the output transients can be controlled by the input signal, and we relate recent models of the redox-based nanoionic resistive memory cell to two common neuronal models, the Hodgkin-Huxley (HH) conductance model and the leaky integrate-and-fire model. We employ a simplified circuit model to phenomenologically describe voltage transient generation.

The main indicators of hygienic quality of milk are the total bacterial count and the somatic cell count. The objective of this paper was to investigate the changes in the hygienic quality of milk due to implementation of the new system of milk payment in Bosnia and Herzegovina in the period of 2010-2013 as well as to determine the impact of season on hygienic quality of milk. The bulk milk samples were collected from milk producers from the whole area of Bosnia and Herzegovina who submit its milk to dairy industry. It was collected 53 363 milk samples which were analysed for the somatic cell count (SCC) and 52 999 milk samples for the total bacterial count(TBC). The results of research showed that the proportion of redeemed milk with the number of somatic cells lesser than 300 000/mL was significantly increased, as well as the proportion of milk producers who produce milk of EU quality (P<0.05). The season had a significant effect (P<0.05) on the SCC. Thus, in spring (April) the proportion of milk with the number of SC < 300 000/mL was significantly the highest (P<0.05) while the proportion of such milk in the autumn period was significantly lower (P<0.05). Significant linear increase (P<0.05) of the proportion of redeemed milk with the TBC < 200 000/mL was perceived. The change in the system of milk payment in Bosnia and Herzegovina resulted with significantly (P<0.05) increased proportion of producers who submit that’s kind of milk. Significantly lower proportion of milk in summer period with TBC < 200 000/mL was determined. It can be concluded that consistent appliance of existing regulations which determine the quality of milk, based on EU standards, leads to the improvement of hygienic quality of redeemed milk, as illustrated by the case of Bosnia and Herzegovina.
