Abstract

The Malagasy Phaseolus vulgaris L varieties analyzed in this study showed the presence of high nutritional elements, particularly protein levels of 20.3899%; 21.3130%; 20.6173%; 23.0134%; 21. 7245%; 21.3049% respectively for the six varieties 55(B), RI 5-2, CAL 98, Ran'omby 1, RI 5-3, Ran'omby 4, as well as carbohydrate contents ranging from 57.4657% for Ran'omby 1 to 65.1171% DM for CAL 98. The presence of essential mineral elements for human nutrition (iron, zinc, magnesium, calcium, potassium, sodium, phosphorus...) and phytochemical families reveal its virtues as a food. This means that Phaseolus vulgaris L is a complete human food.

Abstract

The aim of this study is to examine the correct handling of dangerous goods by Compagnie Africaine d'Aviation (CAA), in order to limit the risks that could arise from non-compliance with the rules governing the safety and security of dangerous goods. A mixed-methods approach was adopted, using descriptive, analytical and comparative methods, as well as interview, survey, observation and documentation techniques. Data collection and analysis showed that air transport of hazardous materials or products by Compagnie Africaine d'Aviation, despite the existence of regulatory standards, does not really comply with the minimum provisions set by the International Civil Aviation Organization and the Civil Aviation Authority of the Democratic Republic of Congo in terms of safety and security. A low level of handling of dangerous goods was observed in first position with 60%, followed by a medium level of 30% and a very low level of 10%. In view of this result, it should be pointed out that resources need to be invested in training and capacity building for personnel handling these dangerous products.

Abstract

This study focuses on the identification of the determinants of Energy Protein Malnutrition (EPM) in the peripheral area of Kinshasa. In a quantitative approach supported by a survey, anthropometric measurements (age, weight and height) are taken from 270 children under five years old.  The use of the Chi-square statistical test made it possible to identify the following determinants of MPE: living in a rural environment, single-parent families and low level of education of the mother.

Abstract

The article considers one boundary value problem for systems of parabolic type, consisting of two differential equations for determining the temperature and moisture content of a lump of raw cotton during drying in dryers. Based on the laws of thermodynamics (the laws of thermal conductivity of Fourier, Newton, conservation of energy, etc.), this problem is formulated as a system of differential equations of parabolic type An approximate solution of the problem under consideration was constructed using the variational-grid method, and a comparative analysis with experimental data was carried out. To solve this problem, was used the Galerkin variational method, i.e. introduce the basis function ji(x) satisfying the conjugacy condition ji(0)=0. A comparative analysis shows that the error in the calculated and experimental data is no more than 4-5%. And this makes it possible to analyze the heating rate in the form of a lump.

Abstract

The present study aimed to observe the effect of thermal variation and steaming time on the rejection capacity of plantain at Gbadolite in the Democratic Republic of Congo. The steamer was used to provide dry heat at the buckling scale according to the temperature and duration of steaming under in vitro conditions at the following temperatures and durations: 50°C, 80, 100 and 120°C for 1', 3 and 10'. Oven-dried subjects were set up in 4 randomized complete blocks, each containing 13 treatments: T0: control or non-oven-dried subject; T1: oven-dried reject at 50°C for 1'; T2: oven-dried reject at 50°C for 3'; T3: oven-dried reject at 50°C for 10'; T4: oven-dried reject at 80°C for 1'; T5: oven-dried reject at 80°C for 3'; T6: discharge steamed at 80 °C for 10'; T7: discharge steamed at 100 °C for 1'; T8: discharge steamed at 100 °C for 3'; T9: discharge steamed at 100 °C for 10'; T10: discharge steamed at 120 °C for 1'; T11: reject steamed at 120°C for 3'; T12: reject steamed at 120°C for 10'; 19; 22; 21; 22; 27; 28; 26; 25; 23; 26; 32; 48; 33 rejects per explant were obtained respectively. Thus, the best treatment remains explants steamed at 120° for 3'. In other words, explants should be heat-excited to stimulate rejection and shorten the weaning period.

Abstract

The present study aimed to evaluate the yield of cassava (Manihot et al.) leaves harvested bimonthly in relation to the level of secondary infection of the crop by MAM in Kisangani and Gbadolite respectively, in the provinces of Tshopo and Nord-Ubangi in the Democratic Republic of Congo. An experimental randomized complete block design was chosen, with 4 replicates and 5 treatments according to infection levels, including Level 0: No symptoms (apparently healthy subject); Level 1: Yellowish spots covering 1/5ème of the leaf blade (light mosaic); Level 2: Spots covering half the leaf blade, and appearance of leaf deformation (moderate mosaic); Level 3: Affected leaves deformed and partly curled up, vegetative apparatus reduced (strong mosaic); Level 4: Almost all leaf blades curled up, vegetative apparatus reduced (severe mosaic); Level 5: Leaves reduced to about 1/10ème of their surface area; on some, the leaf blade becomes non-existent, twigs very short, generally knotted, plant dies within a few months. Leaf yields recorded in Kisangani were in the order of 1.99 T/ha (Level zero, apparent absence of mosaic); 1.73 T/ha (Level 1, light mosaic); 2.13 T/ha (Level 2, moderate mosaic); 1.66 T/ha (Level 3, strong mosaic); 1.16 T/ha (Level 4, severe mosaic) with the Mbongo variety. On the other hand, at Gbadolite, 2.63 T/ha (Level zero, apparent absence of mosaic); 2.67 T/ha (Level 1, light mosaic); 3.01 T/ha (Level 2, moderate mosaic); 2.26 T/ha (Level 3, strong mosaic); 1.89 T/ha (Level 4, severe mosaic) were obtained with the Yasegumba variety. With the exception of levels 1 and 2, MAM caused yields to fall by 13.1 to 41.7% and 14.07 to 28.14% from level 1 (light mosaic) to level 4 (severe mosaic) by adopting bimonthly harvesting in Kisangani and Gbadolite respectively. This harvest is, therefore, one of the best techniques for managing MAM and producing leaves.

Abstract

Many infinite mathematics problems take a lot of work for people, including myself, to deal with. The paper discusses a few typical infinite problems in mathematics, and it calculates out the sum of the infinite layers of the square root of 2; it calculates out the result of the problem consisting of the infinite power of; it demonstrates how to deal with the problem of the infinite decimal; it calculates out the result of the infinite continued fraction; it calculates out the result of the problem consisting of the multiplication by infinite layers of. The paper presents a method of solution commonly useful for most of the infinite problems in mathematics.

Abstract

This study on the valorization of Syzygium cumini fruit pulp was carried out in Antananarivo-Madagascar. The aim was to find a substitute for grape wine at Christian feasts. What drew our attention to the jamuns was their resemblance to grapes in bunches during fruiting and their identical color when ripe. Research undertaken through physico-chemical analyses of these fruits and the products derived from their fermentation has led to the conclusion that ordinary chemical families, such as anthocyanins (0.012 mg/g), produce a wine that is similar to grape wine in taste, slightly astringent, and color, however low its alcoholic strength. So, it would be possible to offer this type of wine that would not make anyone drunk.

Abstract

This study tested the influence of bulb fragments on the rejection potential of plantain ex-situ. The experimental set-up chosen was that of randomized complete blocks comprising 4 blocks and 4 treatments according to the weights of the minisets. Treatments were assigned to line plots under ex-situ conditions. They were made up of the following fragments: T0 (20g fragment), T1 (5g fragment), T2 (10g fragment), and T3 (15g fragment) at a rate of 150 minisets per treatment installed on a propagator in a greenhouse. For each bulb, 4, 17, 18 and 21 rejections were counted, respectively, for the control: T1 (5g fragment), T2 (10g fragment), T3 (15g fragment) and T0 (20g fragment). In the event of a shortage of planting material, the bulb can be cut into mini-pieces of around 10g, i.e., 2/4 of a bulb, in order to increase the rejection potential and thus produce planting material.

Abstract

A person is simultaneously in a material, ethereal and spiritual environment. It is connected to the material environment by gravity. In the ethereal environment, he is capable of levitation. In the spiritual environment, he is perfected to the likeness of the Creator. A person's thoughts have a spiritual essence. Thinking initiates inner speech, which generates gravitational waves. The research is devoted to communication through internal speech, the direction of the development of new technologies and interdisciplinary research on cognitive communication by internal speech in the ethereal environment at the damage of gravitational waves. The transition to cognitive communication based on natural technology will save resources on digital communication. It will also help solve information interaction problems through the noosphere
