The present study was conducted to evaluate the influence of gibberellic acid (25, 50, 100, and 200 ppm) applied on saffron corms previously harvested during different periods (March, June, and before planting) on the growth and the quantitative and qualitative yield of saffron (Crocus sativus L.). The study was carried out in the field during the 2016-2017 and 2017-2018 seasons in the experimental station of the Faculty of Sciences of Oujda (Morocco). The measured parameters correspond, on the one hand, to morphometric measurements and to the determination of the saffron stigma yield and, on the other hand, to the evaluation of the quality of the spice. The results showed that almost all the parameters studied were significantly affected by the factors considered. The treatment of corms just before planting with concentrations of 100 and 200 ppm GA3 showed the highest flower and leaf appearance rate and the highest leaf length and surface area. Moreover, the application of GA3 during the month of March gave the best results in terms of stigmata yield, percentage of large-diameter daughter corms, and the ratio of the number of flowers produced to the total weight of corms. The results of the coefficient of corm propagation revealed that the application of gibberellin during any period improved this coefficient compared to the control. The results indicated that the application of GA3 with concentrations above 25 ppm can improve the growth of saffron and increase its yield under the semiarid climatic conditions of eastern Morocco.

Taking Responsibility

This paper presents a positive philosophy of life developed to support and inspire patients to take more responsibility for their own lives and to draw more efficiently on their known or hidden resources. The idea is that everybody can become wiser, use themselves better, and thus improve quality of life, subjective health, and the ability to function.To be responsible means to see yourself as the cause of your own existence and state of being. To be the one who forms your own life to your liking, so that others do not shape it in the way they prefer to see you. Seen this way, taking responsibility in practice is one of the most difficult things to do. One of the greatest and most difficult things to do in this context is to be able to love. To be the one who loves, instead of being the one who demands love, care, awareness, respect, and acceptance from somebody else.Since almost all of us have had parents who maybe loved us too little and mostly conditionally, we all harbor a deep yearning to be loved as we are, unconditionally. A lot of our energy is spent trying to find recognition and acceptance, more or less as we did as children from our parents, who created the framework and defined the rules of the game. But today, reality is different. We have grown up and now life is about shaping our own existence. So we must be the ones who love. This is what responsibility is all about. Taking responsibility is, quite literally, moving the barriers in our lives inside ourselves. Taking responsibility for life means that you are willing to see that the real barriers are not all these external ones, but something that can be found within yourself. Of course there is an outside world that cannot be easily shaped according to your dreams. But a responsible point of view is that although it is difficult, the problem is not impossible; it is your real challenge and task. If there is something you really want, you can achieve it, but whether it happens depends on your wholehearted, goal-oriented, and continuous attempts. This paper describes the philosophy about seizing the meaning of life and becoming well again, even when there is little time left.

Chilli pepper (Capsicum spp.) is an annual vegetable fruit used as a spice in almost all food and especially in all local dishes in Benin. However, it is neglected in many countries and relegated to the background which does not favor the agricultural development. As a result, its cultivation and conservation are still traditional and face many cultural and post-harvest constraints. The objective of this work is to make an investigation on the current state of the chilli pepper sector in Benin from the planting, growth, harvest until the transformation through storage and preservation. Overall, the review presents all the technical shortcomings hindering the opening of the sector on its socio-economic environment and to make recommendations for the improvement of the quality of chilli pepper sold and consumed in Benin. Thus, the results of this review indicate that there are several local varieties of chilli pepper grown in Benin belonging to three species of the Solanaceae family: Capsicum chinense (annual variety), Capsicum annuum L. (annual variety) and Capsicum frutescens (perennial variety). Its production is generally in rainfed or irrigated crops, in truck farming or on mainland. The best farming technique is the one that begins with the nursery and its success depends on the quality of the plants resulting from this stage. The best methods of storage and preservation vouching a good sanitary quality of chilli pepper are still to be promoted. The main problem encountered by the tillage of chilli peppers in Benin is its contamination by mold during its production and storage. It is therefore important to follow the technical production, storage and preservation routes, to assess the susceptibility of chilli pepper to mold at each stage and to measure the mycotoxins throughout the production chain so as to vouch the safety of chilli pepper consumers and to develop the chilli pepper sector in Benin.

Thinning to one and two flower clusters per fruitful shoot significantly increased total soluble solids and total phenols but had no effect on titratable acidity of de Chaunac grapes in two vineyards differing widely in vine vigor and soil type. Treatment with 50 ppm gibberellic acid 10 days after bloom did not affect juice quality at either location. Grapes from the high vigor, heavy soil site were particularly high in titratable acidity, and potassium content was higher in berries from thinned vines in the same vineyard. An early assessment of wine quality showed the one-cluster treatment to be superior.

This study aimed was the establishment of the genus Brachiaria in the Brazilian semi-arid region. The experiment was conducted from April to June 2016, as a randomized-block experimental design with five treatments and four replicates. Treatments were represented by five Brachiaria cultivars, namely, Marandu, Paiaguás, Piatã, Xaraés and Basilisk. Morphogenetic (leaf appearance rate, leaf elongation rate e stem elongation rate) and structural characteristics (final leaf length, tiller population density e number of leaves per tiller, forage mass, leaf blade mass, stem mass, senescent material mass and leaf:stem ratio) of the forage cultivars were evaluated. Canopy height fitted a linear regression model (P<0,05), with estimated daily increases of 0.50, 0.53, 0.53, 0.54 and 0.56 cm for cvs Basilisk, Marandu, Paiaguás, Piatã and Xaraés, respectively. The number of live leaves in cvs Basilisk and Paiaguás increased linearly (p < 0.05), by 4.3 and 2.8 leaves per tiller, respectively, during the 60-day period. The recommended height at which the growth of Brachiaria cultivars should be interrupted is upon reaching 25 to 35 cm. In the soil-climatic conditions of the Brazilian semi-arid region, the Brachiaria cultivars Basilisk, Marandu, Paiaguás, Piatã and Xaraés are established at 75 days after sowing, which is the recommended time for performing the first harvest or lenient grazing to stimulate tillering.

Abstract The ripening of grapes is impaired by climatic conditions due to the prolonged rainy season and thus facilitates the proliferation of diseases such as grape clusters rotting, caused by the fungus Botrytis cinerea, even before the ideal harvesting point. The aim of the study was to evaluate the effect of gibberellic acid (GA3) on rot and on physical-chemical quality of ‘Sauvignon Blanc’ grapevine. The experiment was carried out in the production season of 2016 and 2017 in Campanha region in Rio Grande do Sul, Brazil. The GA3 treatments were at the doses of 0 (control); 2; 4; 6 and 8 mg L-1 of GA3. The percentage of clusters rotting and maturation index decreased, however, the titratable acidity increased with GA3 doses. The cluster and rachis length increased with application of GA3. The cluster width; cluster, rachis and berry mass and the soluble solids were not influenced by application of GA3. In ‘Sauvignon Blanc’ grapevine, GA3 reduced the percentage of clusters rotting and improved the cluster and rachis length characteristics and titrable acidity.

Abstract. Numerical modeling provides the opportunity to quantify the reaction of lakes on alterations in their environment, such as changes in climate or hydrological conditions. The one-dimensional hydrodynamic General Lake Model (GLM) is an open-source software and widely used within the limnological research community. Nevertheless, neither an interface to process the input data and run the model, nor tools for an automatic parameter calibration exist. Hence, we developed glmGUI, a Geographical User Interface (GUI) including a toolbox for an autocalibration, parameter sensitivity analysis, and several plot options. The tool is provided as a package for the freely available scientific code language R. The model parameters can be analyzed and calibrated for the simulation output variables water temperature and lake level. The glmGUI package is tested for two sites (Lake Ammersee, Germany, and Lake Baratz, Italy) distinguishing in size, mixing regime, hydrology of the catchment area (i.e. the number of inflows and their runoff seasonality), and climatic conditions. A robust simulation of water temperature for both lakes (Ammersee: RMSE = 1.17 °C, Baratz: RMSE = 1.30 °C) is achieved by a quick automatic calibration. The quality of a water temperature simulation can be assessed immediately by a difference plot provided by glmGUI, which displays the distribution of the spatial (vertical) and temporal deviations. The calibration of the lake level simulations of Lake Ammersee for multiple hydrological inputs including also unknown inflows yielded a satisfactory model fit (RMSE = 0.20 m). This shows that GLM can be also used to estimate the water balance of lakes correctly. The tools provided by glmGUI enable a less time-consuming and simplified parameter optimization within the calibration process. Due to this, the free availability and the implementation in a GUI, the presented R package expands the application of GLM to a broader field of lake modeling research and even beyond limnological experts.

The wind catcher or wind tower is a natural ventilation technique that has been employed in the Middle East region and still until nowadays. The present paper aims to study the effect of the one-sided position of a wind catcher device against the ventilated space or building geometry and its natural ventilation performance. Four models based on the traditional design of a one-sided wind catcher are studied and compared. The study is achieved under the climatic conditions of the South-west of Algeria (arid region). The obtained results showed that the front and Takhtabush’s models were able to create the maximum pressure difference (ΔP) between the windward and leeward of the tower-house system. Internal airflow velocities increased with the increase of wind speed in all studied models. For example, at Vwind = 2 m/s, the internal flow velocities were 1.7, 1.8, 1.3, and 2.5 m/s for model 1, 2, 3, and 4, respectively. However, at Vwind = 6 m/s, the internal flow velocities were 5.6, 5.5, 2.5, and 7 m/s for model 1, 2, 3, and 4, respectively. The higher internal airflow velocities are given by Takhtabush, traditional, front and middle tower models, respectively, with a reduction rate between the tower outlet and occupied space by 72, 42, 36, and 33% for the middle tower, Takhtabush, traditional tower, and the front model tower, respectively. This reduction is due to the due to internal flow resistance. The third part of the study investigates the effect of window (exist opening) position on the opposite wall. The upper, middle and lower window positions are studied and compared. The air stagnation or recirculation zone inside the ventilated space reduced from 55% with the lower window to 46% for the middle window and reached 35% for the upper window position. The Front and Takhtabush models for the one-sided wind catcher with an upper window position are highly recommended for the wind-driven natural ventilation in residential houses that are located in arid regions.
