Parameter identification for further utilization as selection criteria to generate new forage maize cultivars is of the utmost importance in the breeding programs. The objective of this study was to evaluate the agronomic characteristics, yield, and nutritional value of experimental maize hybrids with forage potential in the Central Highlands of Mexico. The experiment was conducted in Texcoco, State of Mexico. Treatments consisted of 11 maize cultivars planted in irrigated conditions and allocated in randomized complete block design with three replications. Results indicated differences (P<0.0001) for most variables. Earliness varied from 84 to 109 days, and plant height from 190 to 282.9 cm. In addition, cultivars with Tropical and subtropical germplasm showed an increasing incidence of common rust from 8.3 to 92%. The yield of green forage varied from 37.1 to 80 t ha-1, while the yield of dry matter was from 12.8 to 24.8 t ha-1. In conclusion, the productive potential of hybrids with Tropical germplasm is limited due to their susceptibility to rust. In contrast, hybrids with germplasm from the Highlands showed an outstanding performance. These hybrids were V-107, H157-E, H-161, and H-166E.

In this study, we propose the analysis of a tubular structure undergoing expansion along the axis of the cylindrical material under internal pressure. Both kinematic and dynamic aspects are examined, leading to the derivation of an exact analytical solution using a system of partial differential equations. Simulation results demonstrate that the solution exhibits sinusoidal behavior in all cases. Minor variations result in incremental or decremental intervals, while significant changes in radius cause simultaneous increase and decrease intervals with trigonometric patterns. Additionally, we observe that the second component significantly influences the overall solution behavior compared to the first component.

This study was conducted in Democratic Republic of Congo, in the province of Kwango, chiefdom of Pelende Nord in order to inventory the floristic diversity of forest islands. To study the vegetation, 15 transects 5 meters wide and 60 meters long were set up at random, with 5 transects per forest island. The inventoried plant species were identified using the combination of various identification keys, the botanical classification taking into account Angiosperm Phylogeny Group (APG IV). The results obtained reveal 129 plant species divided into 35 families including 48 species with an average of 25.5 ± 14.4 in the first forest island, 39 species with an average of 20 ± 11.4 in the second forest island and 42 species with an average of 21.5±12.3 in the third forest island. The most represented families are those of Rubiaceae with 45.7%, Euphorbiaceae come second with 42.9% and Fabaceae in third position with 28.6%. This floristic richness shows that if these forest islands are well preserved, they can evolve into forest ecosystems by providing the same ecosystem services.

The objectives of this study are to identify the actors and actions that contribute to the development of the regional area of Kimvula, to demonstrate that the territory of Kimvula is underdeveloped, to show the problems of this situation and the strategies to ensure the integral development and to solve the problem of its poor development. The results obtained from this study affirm that the level of the development is in decline (opinion of 60 percent of subjects surveyed), or in stagnation (opinion of 34.5 percent of subjects surveyed) and without opinion (opinion of 5.5 percent of subjects surveyed). The long-term development of Kimvula therefore requires diversification of their economies into the production of tradable goods. It is also necessary in the medium term because the territory is isolated from a possible reversal, even temporary, in the current trend in raw material prices. Diversification of production can follow several directions. The evacuation of agricultural products is a first path. But also, significant investments in transport infrastructure and the rehabilitation of agricultural service roads. National governments and international development agencies have neglected for too long the potential that the territory of Kimvula represents.

Striga represents a significant constraint to food production. Despite its harmful effects, striga is regularly sought in the markets for uses miscellaneous. The general objective of this work is to collect all the information on the use made of this harmful species. Field surveys were carried out in the 6 regions of Niger (Dosso, Maradi, Niamey, Tillabéry, and Zinder) and the choice of surveyed, was done at random. 340 people were interviewed including 236 men and 104 women. The survey results showed that 76% of surveys use striga and it is involved in 10 categories of uses, namely fodder, soil fertilization, the mystical, the dye, the fuel, the fight against erosion, the insecticide, human food, traditional human and animal medicine. The uses most cited are fodder with 35.10% followed by human medicine (22.12%). This study made it possible to inventory 31 diseases for which striga is used for treatment of diseases in humans.

The fundamental tool of this study is the two and three-dimensional modeling software DELFT 3D. It was used to model the hydrodynamic processes of the harbor of San-Pédro (Côte d’Ivoire) and its immediate marine environment, with the input parameters such as tidal variations in tides and river flows, as well as average annual wind speeds. Studies focused on the behavior of current fields, water level variation, and the nature of the tidal wave. The calibration of the model followed by an analysis of the literature led us to choose a coefficient of 0.03 m-1/3.s, with which the model performs very well. Current fields tend to follow the wind direction, parallel to the coast at sea, while they fit the morphology of the roadstead. At sea, currents are exclusively linear at low water, and exceptionally gyratory at flood stage in front of the San-Pedro river outlet. In the roadstead, they are gyratory and linear, alternating in some places and permanently gyratory in others. The shape of the current also depends on its speed, with a limit of 1.5 cm/s for the appearance of gyratory currents at lower speeds. The current speeds in the roadstead are between 0 and 6 cm/s while at sea they are between 5 and 11 cm/s, exceptionally between 10 and 34 cm/s in front of the outlet. As water level variations are highly dependent on tide and season, they are greater in the roadstead (4cm on average) than at sea. The wave is stationary in roadstead, with the existence of the seiche phenomenon, and progressively dominant at sea. The seiche wave determines the directions of entry and exit of water from the roadstead, with low tide corresponding to an outflow of water and high tide, a period of transition between the ingress and egress of water from the roadstead.

Cowpea varieties respond differently to plant population per hectare due to their intrinsic morphological differences and the influence of the weather and soil condition in growing environment. The objective of this study was to investigate the effect of plant population on growth and yield characters of erected and semi-erected cowpea varieties in two agroecological zones of Burkina Faso. A split-plot experiment with three replications conducted in two consecutive rainy seasons, 2019 and 2020, at Kamboinse and Farako-Ba research stations was used to determine the effect of three plant population, 62,500 (control), 95,258 and 111,111 on four improved cowpea varieties, KVx745-11P, Komcalle, Tiligre, Neerwaya. The results showed a significant variation of fodder and grain yield in both locations. At Farako-Ba the combined years data recorded the values of 3740.50, 5240.94 and 5164.02 kilogram per hectare for fodder yield and 1124.14, 1242.93 and 1372.93 kilogram per hectare for grain yield at the plant population of 62,500, 95,238 and 111,111, respectively. The same trend was Observed in Kamboinse with slightly higher average means of fodder and grain yield which were 4300.75, 6446.06, 6699.06 kilogram per hectare and 1285.82, 1481.06 and 1650.03 kilogram per hectare, respectively. From the study it is also noticed that grain and fodder yield were impacted by genotypes and environment. The positive relationship between plant population, fodder and grain yield suggest that improved cowpea varieties yield can be substantially increased with the plant population of 111,111 per hectare.

Background: Tuberculosis (TB) is a bacterial infection that can affect many organs including the pleura, and its diagnosis is not always easy. Adenosine deaminase (ADA) has been developed and widely used for the diagnosis of tuberculosis. Objective: To determine the diagnostic utility of adenosine deaminase (ADA) in a series of 80 pleural effusions, and whether pleural ADA can replace pleural biopsy in the evaluation of suspected pleural tuberculosis. We also propose a review of the literature on the characteristics, metabolism and clinical uses of ADA for the diagnosis of pleural tuberculosis in clinical practice. Methods: This is a retrospective study of 200 patients with pleural effusion, of whom 80 patients had an adenosine deaminase assay in pleural fluid. The study was conducted at the day hospital of Moulay Youssef Hospital, CHU Ibn Sina of Rabat, during the year of 2018. Results: Among 200 patients admitted for pleurisy exploration, 80 patients had benefited from adenosine deaminase assay, 90% of pleurisies were of tubercular origin, 75% were retained on histological arguments (by pleural biopsy), while the remainder were retained in front of clinical, biological, radiological and evolutionary arguments. The median pleural ADA level was 53 IU/L. Conclusion: ADA is a rapid and precise means of detecting tuberculous pleurisy, it can be used to support the diagnosis and in particular in case of absence of histological evidence either in front of the impossibility of realization of a pleural biopsy (child, effusion of small abundance), or in front of a not contributive anatomo-pathological result.

To reach our research period, we began our study in October 2017 and completed it in June 2018, nine months corresponding to an academic year. Higher education and university institutions would therefore have everything to gain from turning to applications dedicated to learning via this social media. Our study has as its field of research three higher education institutions, namely I.S.P/KANGU, ISTM/Tshela and ISEA/Tshela. Indeed, social networks became popular in the 2000s. They are increasingly used in different ways in the field of information and communication technologies. In view of our scientific reflection, all our respondents often consult social networks. Clearly, the three higher education institutes in the area provide good support to students in the regular use of the Internet. As an illustration, for Internet connection, seventy-seven students or 62.07% use cell phones, thirty-three or 28.49% use Internet cafes and eleven with a percentage of 9.48 use modems. Currently, Facebook is the most used social network. We noted eighty-two or 70% of our respondents against twenty-nine or 25% for WhatsApp. Twitter and YouTube are less used by our respondents.

To make the quality control of the leukocyte numbering in some laboratories of the former city of Tshela, was the overall objective of this research. Blood samples for leucocyte (white blood cell) counting were taken from patients at Pandji General Reference Hospital, Mimvanza Reference Health Center and Kilayika Hospital Center and the latter were examined at the laboratory of the Higher Institute of Medical Techniques of Tshela (ISTM /Tshela) with respect for standards, enacted on the subject by the WHO. Indeed, the quality control results of the numbering of white blood cells showed that the quality control parameters were good except for the parameter expression of the results with bad score at C.S.R/Mimvanza and C.H. Kilayika as well as the task parameter of Laboratory Technician with an average index at the Pandji General Reference Hospital in Tshela. In addition, the distribution of data according to age group revealed that the age group from 1 to 16 years was the most encountered with 36 cases out of 90, or 40%, on the other hand, that from 16 to 30 years was the less observed with 14 cases out of 90 or 16%. This predominance of the age group of 1 to 15 years could be justified insofar as this category contains a vulnerable group, that of children from 0 to 5 years old. It was found that according to the presentation of the data of the number of white blood cells in the laboratories, that in the sense of the HGR/Pandji, which has a high frequency of normal results with 16 out of 42 normal cases, i.e. 38 %. According to the overall quality control results of the white blood cell count, quality of the white blood cell count, the normal results were superior compared to the abnormal, with 64 cases out of a total of 90, or 71% From the comparison of the quality control and lab results, we noticed a considerable discrepancy between the lab results and its results from our study. After our analyzes we found that quality control of the WBC count was non-existent in medical laboratories, which is the cause of results that sometimes deviate from reality or standards. Our hypothesis according to which there would be the absence of quality control in the leukocyte numbering which would be the basis of the errors recorded in the expression of the results was fully confirmed.

DNA sequence DNA Sequencing is the first step in establishing phylogenetic trees, protein structure prediction, diagnosis of cancer, discovery of drugs and hence its importance cannot be underestimated. DNA sequencing finds its use in the diagnosis of oral squamous cell carcinoma (OSCC). Oral Cancer is the most common occurring malignancies in the world, especially in India where the prevalence for smoking, Areca nut chewing coupled with a lifestyle that encourages these two activities as fashion are left many people diagnosed with OSCC. Patients with this OSCC are more likely unaware of its side effects and over time might suffer from facial deformity. The importance to understanding the symptoms, prevention and treatment of oral cancer is very much essential today. In this paper, we looked at over 2000 odd papers published and look at the correlation between the next Generation DNA sequencing algorithms (NGS) play an important role in diagnosis of OSCC. This is a further study on some of the papers which have highlighted NGS role in OSCC Diagnosis. We did like to see a comprehensive review on the papers published so far. In the discussion, we will see frequently mutated genes in the OSCC, recent discoveries and OSCC treatment based on the findings.

In this study, based on a sociogenetic approach involving 7 teachers and 182 fourth-year scientific students from 21 schools offering the scientific section in Inkisi and Kimpese, two cities in the Kongo Central province of the Democratic Republic of Congo, the central question focused on identifying the main initial representational obstacles in kinematics among these students and their origins. As a result, it was noted that most teachers were unaware of these initial representations. In addition, the students had primitive, negative and collective conceptions, stemming from educational and cultural contexts, relating to the basic notions of kinematics such as motion (moving), time (duration), trajectory (distance), speed (rapidity), rectilinear motion (movement on a flat surface), uniform motion (fixed), varied motion (accelerated) and free fall (falling suddenly and involuntarily). There is thus a persistent and evolving contradiction between these initial representations-obstacles and the new knowledges that teachers have to transmit.

Economic activities in the Central West region of Burkina are dominated by agriculture. This agriculture, dependent on climatic parameters (rainfall, temperature), is under the influence of climate change. Understanding the state of the climate and its evolution can guide effective adaptation measures. This article aims to contribute to knowledge of the state of the climate, its variabilities and trends in the Central West region of Burkina Faso. The results of the analyzes indicate that the region is characterized by a tropical climate subdivided into two types. The North Sudanian type characterizes the northern part and the South Sudanian type the southern part. There is strong variability in rainfall and temperatures from 1991 to 2020. This variability is marked by a relatively dry period (1988-2002) characterized by an average rainfall of 705.95 mm and nine years of rainfall deficit, the excesses of which are recorded in 1997, 2000 and 2005. The second period (2003-2017), wetter, is characterized by an average of 828.58 mm, with ten years of excess rainfall. The year 2012 recorded very excess rainfall. Temperatures have fluctuated with an average for the same period of 29.11°C. High temperature values ​​are observed in 2020 and 2005 with 29.60°C and 29.55°C respectively. The low averages were recorded in 1992 and 1991 with 28.04°C and 28.41°C respectively. The analyzes conclude a trend towards a slight increase in precipitation and a regular and significant trend towards an increase in temperatures.
