Agriculture today is faced with the need for profound change to meet current challenges, whether they are environmental, climatic, food, social or economic. Thus, sustainable agriculture aims to move away from dependence on inputs with a high environmental impact (pesticides, fertilizers) in order to move towards new forms of natural resources. Anthill soil provides excellent organic manure, especially for poor soils that do not retain water. This study presents the results of the work on the effect of anthill soil compared to the effects of mineral and organic inputs on the development of vegetable crops during the hot dry season in the Sudano-Sahelian zone. The physico-chemical characterization of the soils was carried out. The biometric parameters studied were height, diameter at the root collar, number of leaves and weight of plants. The experimental device used was a total randomization comprising the 6 treatments. The soil at the site is loamy and slightly acidic. The carbon, nitrogen, phosphorus and potassium contents of anthill lands are higher than those of surrounding soils. Overall, the means of heights, neck diameters and number of leaves of cabbage and beet lettuce plants with 100% and 50% anthill soil substrates are significantly different from other treatments (mineral manure, organic manure, substrates of 10% anthill soil and control soil). The land of anthills has a significantly different impact on the production of cabbage, lettuce and beet.
Healthy subjects, considered as « reference », generally biological samples whose analysis provides acceptable results as « reference values » to assess the pathological states of patients of the same age, of the same sex, living in the same environments and environmental conditions.One of the possible means of studies that a medical biologist can use for research in determining baseline values of hemoglobin and hematocrit and to compare the results obtained in sick subjects to those in healthy subjects, because hemoglobin is a heteroprotein whose main role is the transport of oxygen (O2) and carbon dioxide (CO2).
Globalization has led to greater income, due to the rapid digital transformation that started to seem so important under the current circumstances because of the Covid-19 virus. To handle the performance issues the supply chains has to become smarter and all the researchers argued on the necessity of having smart SCs. The automotive industry plays a significant role in the advancement of technology development and its application, despite that, the research field lack of articles that deal with SCM 4.0 in this industry. The aim of this paper is to present a literature review of Supply Chain 4.0 and Industry 4.0 in the companies also to study the relationship between all these parties, to give us a ground to continue our works consisting the study of the impact of the implementation of SC4.0 on the industrial performance of automotive companies in a developing country such as Morocco.
The implementation of a circular economy for empty agrochemical containers in areas where agriculture is intensive and the use of agrochemicals is in large quantities, is necessary to reduce the impact on the environment and people's health. Training the primary producers of empty containers and agrochemical companies in the correct management of hazardous waste, as well as promoting the participation of the social and private sectors in activities of recovery and recycling of hazardous waste are some strategies aimed at avoiding the disposal end of empty agrochemical containers in the soil, bodies of water or incineration without controls, seeking in this way the recycling, co-processing or treatment of empty agrochemical containers.
This study focuses on urban dynamics and basic services. It focuses on Agboville, a historic city created ex-nihilo by settlers. The main objective of this study is to highlight the correlation between urban growth and the development of basic services at different periods.The methodological approach consisted in exploiting the Master Urban Development Plans (PUD, 1970; 1994 and 2018) and the reports of the various INS censuses (RGPH, 1988-98 and 2014). It was completed by the exploitation and selection of aerial photographs from the IVC (1970) and KOKUSAI (1994) missions at CCT/BNETD for cartographic purposes. It also involved interviews with local authorities and direct observation of available basic services.The results show that there is a significant de-correlation in the current development of Agboville between urban sprawl and its networks. The city is expanding without following the facilities. The result is an imbalance related to the phase shift in the spatial dynamics and the growth of the facilities. The urban dynamics led by a population in constant evolution takes precedence over the development of public services. This situation leads to a deterioration in access to basic urban services because population growth makes the available basic services de facto insufficient.
The pure scientific interpretation, along with educational and psychological interpretation in the field of learning, is important in understanding and realizing the learner's responses in the educational learning process, and exploring the results of research in the heart and brain and clarifying the importance of knowledge in heart and brain pedagogy. Heart and brain properties. The first of these characteristics between the heart and brain in the field of learning is the property of the heart health being linked to the continuity of learning and the activity of the brain, also the characteristic of neurons in the heart and the brain that generate perception and understanding, as well as the memory property in the heart and brain have an effect on learning, in addition to the characteristic of the heart, the beginning of learning in the brain, Where those characteristics were linked to the educational learning process and hadiths of the Messenger, may God bless him and grant him peace which related to these characteristics, to produce an integrated understanding between the heart and brain in each characteristic.
The department of Oume is a local rice production area. Yet in Cote d'Ivoire, women occupy a central place in subsistence agriculture. This article aims to examine the contribution of women in the development of the rice sector in the department of Oume. The methodology adopted to achieve this objective combined documentary research and field surveys. The results show that women, directly or indirectly, are key players at all stages. They operate small plots. The activity is 82% in the hands of foreigners. A large part of the income generated is used for family expenses, which often undermine their financial autonomy.
This paper analyses the implementation and calibration of the Heston Stochastic Volatility Model. We first introduce the model, provides theoretical motivation for its robustness and hence popularity and explain how characteristic functions can be used to estimate option prices. Then we consider the implementation of the Heston model, showing that relatively simple solutions can lead to fast and accurate currency option prices. In this work, we perform several tests, using both local and global calibration to evaluate the Predictive Accuracy of the Heston Stochastic Volatility Model for currency options.Our analyses show that straightforward setups deliver excellent calibration results. All calculations are carried out in MATLAB and included in the paper. All the MATLAB’s codes required to implement the model are provided in the appendix A.
This paper tackles about design of a device allowing a photovoltaic solar installation to follow the flat movement of sun in order to optimize electrical energy production. This device called solar tracking system is a structure that allows tracking the apparent movement of the sun in real time. To achieve this, we have chosen to use the active or slaved tracker. The improvement of the energy performances by using a double axis solar tracker is also studied. The observation of the power curves according to the influence of the received light intensity shows a maximum of 180W in the form of a plateau between 10: 50 and 14: 00 (for 3 hours) local time for the double axis system while a maximum of 175W is recorded from 12: 50 to 13: 50 (1 hour) for the single axis tracker and a maximum of 170W (for a few minutes) at noon for the fixed system. From the analysis of these results, a significant gain of about 26.20% for the dual axis tracker compared to a fixed installation was obtained.
The present study consists with the management of the household refuse in three various districts (Mambenga, Ibanga and Air Congo) of the town of Mbandaka of RD Congo.Our investigations were carried out in three hundred (300) households because of 100 households per district. These households were contained in «bunches or pockets» presenting the same characteristics or similarities. Thus, we obtained 6 bunches or pockets of the 50 households each one because of two bunches per district .The results obtained show that: the majority of the households of these districts do not have dustbins.3% only of the households of Mambenga district have the dustbins counter 2% of Ibanga district.In the district, 92,8% of households carry out against the hiding of the refuse 95,98% in Wangata and 93,33% with Bolenge.the major part of our surveyed are adults who are in the age bracket of 19-49 years for the three districts. The heads of the households whose age is lower or equal to 18 years represent only one small proportion among surveyed.as for the function of surveyed, the majority are agents and civils servant of the state, except in the zone of health of Bolengeor the peasants account for 50%.compared to the level of studies, it is released that the majority of the heads of the households finished the secondary studies, followed those which made the higher and university studies.As a result, the absence of functional structures capable of ensuring the collection and disposal of household waste through households in the city of Mbandaka leads to illegal and uncontrolled dumping in the streets and neighborhoods of this city.
The systematization of ultrasound in the 1st trimester with a search for the nuchal translucency has made it possible to detect numerous pathologies, in particular cystic hygroma, the prevalence of which can reach 2%, and which is defined as having a retro and laterocervical poly cystic mass, These cystic formations are composed of multiple compartments of varying size and containing a liquid; and they are microscopically defined as new cavities formed in the connective tissue and lacking a classic cystic wall, that is to say, they are pseudo-cysts without an internal coating, hence the interest in differentiating them from cervical cystic lymphangioma which has a lymphatic endothelial type coating of variable volume, related to sequestration of lymphatic fluid in the nuchal connective tissue. And which is generally unilateral left anterolateral, and can also involve the shoulder.And also differentiating them from the occipital meningocele by the demonstration of a defect of the bone closure at the level of the cervical spine.Cystic hygroma is often associated with karyotype abnormalities of up to 80% made of monosomy X or trisomy 21 or others, as well as other morphological abnormalities; cardiac, diaphragmatic, skeletal or a set of syndrome. A good knowledge of the factors of poor prognosis makes it possible to inform prenatal counseling and set up correct management.
The physical reality is often very complicated to be able to analytically solve mechanical problems. Currently, the only approaches making it possible to meet these needs are based on numerical methods based on the discretization of the problems. In mechanical and civil engineering, significant efforts are currently focused on the use of numerical simulations to solve these problems. This work is a comparative approach focusing on the analytical method to solve the problem of the bending of a beam and a numerical approach based on simulation by the Cast3M calculation code. The results obtained are of great agreement.
Job satisfaction raises worrying questions these days that no business of any character can shy away from. This article also follows this perspective and focuses on the analysis of job satisfaction according to Herzberg's two-factor theory. Our concern is to know what are the main factors that provide satisfaction to the workers of the Congolese Control Office (OCC/GOMA). The objective here is to understand the main factors promoting satisfaction among all workers in this organization. In response to our concern, we estimated that the main factors promoting job satisfaction would be on the one hand: staff allocation, communication, working conditions, company organizational policy, salary (remuneration), job security, safety at work, human and technical supervision (extrinsic factors) and on the other hand: attractiveness to work, autonomy, authority, advancement in rank, the degree of responsibility, innovation as well as recognition (intrinsic factors) unlike Frederic Herzberg who stipulates in his theory of two factors that only the above-mentioned intrinsic factors provide satisfaction to workers. It remains to discover the results in the following pages.
The development of biodegradable food packaging is one of the environmental protection issues. The aims of this study is the development and mechanical characterisation of bio-composites that can be used as food packaging based on Musa sapientum leaves and cassava starch. The physical characterisation of the constituents showed that the water content of the starch and the leaf fibres used are 10.44 ± 0.51% and 10.88 ± 1.08% respectively. The water absorption capacity of the leaf fibres and the starch are respectively 33.33 ± 4.44% and 76.67 ± 4.44%. Particle size analysis has shown that 99.93% of the fibres used are less than 1mm in size. The material samples were made by compression moulding and are composed of 10 to 25% starch with 50% water. The Young's modulus in bending of the materials produced varies between 0.07 and 3.37 MPa and the breaking strength in bending between 5.48 and 29.29 MPa. These two parameters increase with the starch content. In tensile strength, the materials obtained are fragile and have low deformation at break varying from 0.61% to 1.53%. The tensile strength of these materials varies between 0.01 and 0.99 MPa and increases with the starch content. The best formulations would be those containing 20% starch with 50% water. The process developed could enable the development of innovative materials for biodegradable food packaging.
It is estimated that more than 2% of pregnant women have hypothyroidism and that the incidence of treated hypothyroidism prior to pregnancy is around 0.3% of pregnancies. In the majority of cases, hypothyroidism is mild and is due to an autoimmune mechanism, as evidenced by the presence of anti-TPO or antithyroglobulin antibodies. Pregnancy may be indicative of a fruste form, related to asymptomatic autoimmune thyroiditis, which is unable to increase its hormone production to meet the specific needs of pregnancy. It can also be the consequence of moderate or severe iodine deficiency. Moreover, thyroid balance during pregnancy is essential for good fetal brain development. In fact, several studies have shown that children born to mothers who are not or insufficiently substituted for hypothyroidism have lower intelligence quotients than the general population. In addition, other maternal consequences (gravid hypertension, pre-eclampsia, etc.) and fetal consequences (IUGR, intellectual deficit) of hypothyroidism during pregnancy have been described. Although current recommendations suggest targeted screening of patients at risk of hypothyroidism, it is desirable that, in the near future, this screening becomes systematic as soon as the diagnosis of pregnancy is confirmed. L-thyroxine treatment should then be rapidly initiated (or adapted in the case of known hypothyroidism prior to pregnancy) with the aim of achieving a TSH of less than 2.5 mIU/l. In all cases, iodine supplementation should be offered from the preconceptional period through to breastfeeding.
For nearly a decade and a half, some foundries that recycle scrap metal have been established in Kinshasa, the capital of the Democratic Republic of Congo. These foundries produce annually, as do other foundries, thousands of tons of solid waste, the mismanagement of which was demonstrated in our previous article in the same press. The waste from the foundries being counted among the dangerous waste, it immediately seemed useful to us to determine their chemical composition.After chemical analyses by X-ray fluorescence spectrophotometry (XRF) on 15 samples of slag and 15 samples of sludge from three of the said foundries, the following results were obtained (i) qualitatively, the sludge of the foundries is composed of Na2O, CaO, Cr2O3, MnO, Fe2O3, NiO, CuO, La2O3, Eu2O3, Yb2O3, OsO4, Br, SiO2, K2O, TiO2, V2O5 and ZnO while the slag contains in addition to these last components Ti2O3, Sc2O3, SrO, ZrO2, Nb2O5, RuO2, BaO, Re2O7, Al2O3, Au, MgO, Rb2O and HgO, (ii) On the semi-quantitative level, the chemical analyses indicate that Fe2O3 is the most preponderant component in the sludge with an average mass concentration evaluated at more than 85%, followed by Na2O [6.33%], SiO2 [5.3%], MnO [1.5%]. Eu2O3, Cr2O3 and CuO have concentrations in the order of the tenth (10-1), while the majority of the remaining components have concentrations in the order of the hundredth (10-2), except Re2O7, ZrO2, SrO and V2O5 whose concentrations are small in the order of the thousandth (10-3). On the other hand, the main component of the slag is SiO2 concentrated at 36% of the average total weight, followed by Fe2O3 [23%], MnO [15.5%], Al2O3 [10%], Cr2O3 [1.5%], Na2O [1.1%] which are the major components. TiO2, BaO, ZnO, MgO, SrO, K2O, V2O5, RuO2 have concentrations on the order of tenths ranging from 0.8 ≥ x ≥ 0.112, ZrO2, Eu2O3, Nb2O5, Re2O7 have concentrations on the order of hundredths ranging from 0, 047 ≥ x ≥ 0.02 and NiO, Au, Sc2O3, Ti2O3 and Br have relative concentrations on the order of thousandths ranging from 0.00333% ≥ x ≥ 0.001%.The comparison of the different compositions of the sludge and slag indicates that the slag from the FAMECO smelter, not only has several components related to the other two smelters, but also has higher or lower relative concentrations than the other two. Finally, the pooling or mixing of sludge and slag at the time of disposal indicates that the contribution of pollutants from the slag is far more abundant (78%) than from the sludge (22%).
The aim of this work was to determine the reasons for organ seizures at the slaughterhouse level and the economic and social impact of such seizures. A total of 2,597 carcasses were inspected during this study, of which 283 cattle (10.90%) and 893 sheep (34.40%), 1,419 goat (54.63%) and 2 camellia (0.07%). The month of February 2020 recorded the highest rate of slaughter, 1075 head (41.40%). The analysis of the data showed that male and female goats constitute the most important slaughter. Overall, the proportions are 80.95% for females compared to 19.05% for males of all species combined. For partial seizures, it is noted that distomatosis is the most important reason for seizure with 557 pieces, i.e. 40.95% of the total number of pieces seized. Furthermore, after all calculations, it is noted that the seizures recorded during three months of monitoring resulted in a total loss of around 76,000 FCFA. In February 2020, the losses were the highest with 46,500 FCFA. These investigations were carried out in the communal slaughterhouse of Tillaberi, in order to contribute to enrich the scientific sphere, but also to identify the dangers, sources of disease in humans and to provide our doctors with a lead to improve public health.
Cornual pregnancy is a rare form of ectopic pregnancy, involving the uterine horn. It constitutes a gynecological emergency due to the major risk of cataclysmic uterine rupture which can jeopardize the maternal vital prognosis. Its seriousness lies mainly in the diagnosis. The management of this formerly exclusively surgical pathology has evolved to medical treatment, or even the abstention from any therapy. Our main objective is to assess the effectiveness of the different types of care offered to these two patients.
Financial Inclusion has recognized as a new exemplar in reducing poverty and accelerating economic growth in the developing countries like Bangladesh. The aim of this study is to examine the relationship as well as the impact of financial inclusion on Gross Domestic Product (GDP) of Bangladesh economy. Secondary data of twenty years from the banking industry of Bangladesh has been employed and empirical data was analyzed using multiple regression model. Findings of the study indicated that bank branches and active mobile money accounts which are used in this study as the proxies of financial inclusion have a positive and statistically significant relationship with GDP, whereas the other proxy variable advance-deposit ratio has a positive but statistically insignificant relationship with GDP. The results of this research will be helpful for the mobile Banking service providers, banks, central bank, policy makers, regulators, Government, industry players and development agencies in formulating policies and taking necessary steps for the sustainable development of financial inclusion and economy at large.
