Iris Publishers - Academia.edu | Depression from Sadness to Melancolia - Journal of Neurology & Neuroscience- Iris Publishers Sometimes we have felt so sad and so disappointed for a few hours or days, situation that leads us to sleep badly, have awakenings consists before, decreased appetite, easy crying, tiredness, attention deficit, grumpy, even wanting to “swallow the Earth” which is a small thought to “want to die”; These situations are normIn the mood swings we experience throughout the L day or in a few weeks, and that is recovering with the passage of time, thanks to the adjustment in your brain neurotransmitters experience, we have already commented that they are chemicals in the brain that allow to carry out the different phases of thought. This series of symptoms or sensations We come from a series of external stimuli or characteristic experiences that all, absolutely everyone must go through once in our lives, as are the heartbreaks, both marital separation and t...

Biofertilizers, fertilizers made from organic residues, could replace some mineral fertilizers, reducing energy consumption and resource mining. The main treatment options are composting, anaerobic digestion, drying, pyrolysis and combustion, they can be used alone or in combination. The quality of biofertilizers depend both on the original residue and on the treatment, but in most cases not all the nutrients are immediately available to plants. It is difficult to predict how available the nutrients are, and when they will become available. The methods to assess and predict nutrient availability are reviewed. Furthermore, the effect of biofertilizers on the environment in the form of nutrient losses and greenhouse gas emissions are reviewed and compared to mineral fertilizers. There is a need to produce biofertilizers with better and more predictable qualities, and also to understand their effects over multiple seasons.

Drought is the most important limiting factor of the agricultural plants production in Egypt and the world. Nitrogen application management under water limited condition needs to be refined for low yielding environments. Therefore, to see how restricted irrigation and different nitrogen fertilizer affect yield, its components, water use efficiency and nutrients uptake of wheat, an experiment was conducted in a semi-arid area in Assiut, Upper Egypt in 2013/2014 and 2014/2015. Split-plot experimental design was used, based on a complete randomized block design with three replications. The variables were two water treatments and three levels nitrogen fertilization. The main plots were used to express irrigation regimes (100% of water requirements (I 100 = 5370 m 3 ha −1 ) and 75% water requirements (I 75 = 4027 m 3 ha −1 )). The split units were assigned for nitrogen fertilizer levels (N 120 =120, N 180 =180, and N 240 =240 kg ha −1 ). The results showed that fertilization o...

On the meadow-chestnut soil of heavy mechanical composition we studied the productivity of promising varieties of winter durum wheat Grain, de-pending on the doses and timing of mineral fertilizers on the background of irrigation and semi-steam systems of soil treatment in irrigation of the flat zone of Dagestan. The purpose of the research was to obtain experimental data for the development of cost-effective and environmentally friendly resource-saving technology of cultivation of promising varieties of winter durum wheat Grain in the flat zone of Dagestan. The novelty of the research is that for the first time in the conditions of irrigation of the flat zone of Dagestan, the optimal doses of mineral fertilizers and the terms of their application for winter durum wheat, providing a significant in-crease in yield and grain quality were studied and established. On average, for 2014-2018 the maximum yield of the promising Grain variety-5.45 t/ha, on aver-age for 2014-2018, wa...

The study aimed to provide valuable information for the promotion of vine by-products in fuelling small-to-medium size enterprises near wine/spirit processing industries. The objective was to evaluate and compare the ashes produced from both fixed and fluidized bed combustion of these wastes and their mixtures. Ashes were characterized by mineralogical, chemical, thermal and fusibility analyses and water leaching tests were conducted to remove problematic elements. Slagging/fouling propensities of ashes were determined, and their environmental impact and potential uses were assessed.

World Journal of Agriculture and Soil Science The paper summarizes the results of studies of the role played by the plant leaf extracellular space in the regulation of mesophyll cells water exchange, photosynthesis and export of assimilates to consuming sink organs. When comparing different methods of assessing water exchange rates, the participation of the plasmalemma in the formation of the leaf water potential was shown. Using the in vivo method of extracting the contents of the apoplast, the dynamics of the exit and movement of labeled photosynthetic products through the extracellular space was traced. It was shown that there is a circulation of assimilates in the plant. As the sugars move downwards along the phloem, they partially escape into the extracellular space and are carried away upwards by the transpiration stream, where they re-enter the leaves that have completed growth and are re-exported. This creates a common pool of photosynthetic products, which serves ...
