INNOVATIVE AND TECHNOLOGICAL PECULIARITIES OF TEACHING OF CHILDREN'S POETRY OF THE TURKIC NATIONS AT THE BEGINNING OF THE TWENTIETH CENTURY
Authors:   Khoja Akhmet Yassawi International Kazakh-Turkish University, Mukhamedzhanova А.В.
Published: April 2023

This article considers the innovative and technological features of teaching humanity disciplines, including Kazakh literature, with the orientation of the teaching process in the higher education system to national values at the present time. The innovative and technological features of innovative teaching of children's poetry of the Turkic nations at the beginning of the twentieth century are studied. It is determined that the core of the children's poetry of the Turkic peoples awakens in modern youth the desire to know the deep history of our roots. In teaching of literature in higher educational institutions, the emphasis on the educational power of artistic works is placed on modern approaches to understanding the meaning of the art of words, fiction in the upbringing of personality in some cases, when in the era of modern globalization the human being is changing, moving away from spirituality. The article deals with the possibility of dividing classes into several groups, depending on the traditional and non-traditional nature in the modern education system. In the training of philologists, specialists in language and literature in higher vocational education, the following several general didactic principles of teaching literature (consistency and accessibility, activity of teaching literature, etc.) and heuristic methods of teaching, cognitive teaching methods are analyzed. This article considers the classification of scientists-methodologists’ principles in teaching disciplines in the process of education system: 1) methodological principles; 2) scientific principles; 3) psychological principles; 4) individual didactic principles. Methods of solving creative problems are divided in two groups (logical and heuristic). Features of the classification of heuristic methods of teaching are considered. Classification of cognitive methods of teaching into scientific methods, disciplines, metasubject methods and creative methods of teaching are pointed out.

Published: April 2023

The article analyzes in detail the problem of teacher training. There are many changes in the development of education. One of them is the implementation of inclusive education. The analysis of the research of foreign and domestic scientists will be carried out, the problems faced by teachers in inclusive education will be clarified. The importance of creating an inclusive educational environment in general education organizations is increasing at the request of modern society and the market. In the modern world, there are two different opinions in the education of people with special educational needs. The first is when teachers of a secondary school consider it necessary to master special pedagogy, psychology and psychological characteristics of children, the second is when people with special educational needs need the help of only special specialists. And these opinions cause many contradictions. The indicators and features of several authors on professional training for the organization of an inclusive environment are given. The barriers faced by teachers in the process of working with children with special educational needs are specified. Checks the level of professional training of teachers for an inclusive educational environment for the object chosen by the authors. As a result, the competencies necessary for the professional training of a teacher for an inclusive educational environment are determined. Identification of competencies and knowledge of the ways of their formation in the formation of professional training of teachers leads to great results.

Published: April 2023

The main objectives of the article are to identify research gaps on green innovation and competitive advantage and develop a nomological framework. The desk research strategy used to achieve the objectives. The literature survey was based on the articles which were found in databases such as Emerald, JSTOR, Scopus, EBSCO Host, Oxford University Press, Sage, Research Gate, and Wiley Online Library, from the year 2000 to 2022. 500 articles were rejected grounding that those are not directly relevant to the field of green innovation, available without full text, and not scientific. 84 articles were selected as the sample of the study. 10 research gaps were identified and among them, two gaps (1 and 2) were considered as empirical gaps while the other five gaps (3,4,5,6,and 7) were theoretical gaps. The last three gaps (8, 9, 10) were contextual gaps, sector-wise (service sector) gaps, and methodological gaps. Based on the identified research gaps, a nomological network was developed for further empirical studies. This study is limited to conceptual model development; however, shade a new light on green innovation by injecting a theoretical perspective into the emerging field of green innovation. This study donates an important contribution to the body of knowledge on green innovation because it addresses significant knowledge gaps amongst relationships and the effects of identified variables, which have not been previously discovered. Further, it has presented vibrant contributions to managers of the apparel industry and policymakers to depthunderstanding of the concept of green innovation and competitive advantage.

Reverse Osmosis Membrane Scaling Inhibition using Kinetic Degradation Fluxion Media
Authors: Shoqeir Jawad A.H
Published: April 2023

Membrane fouling can lead to reduced efficiency, increased operating costs, and shorter membrane life, which can ultimate[1]ly impact the quality of potable water produced from seawater. The use of Kinetic Degradation Fluxion (KDF) media as a pretreatment method is promising because it can potentially reduce fouling caused by CaCO3 scaling and improve the per[1]formance of RO membranes. The study's methodology, which involves comparing two identical reverse osmosis systems with and without KDF pretreatment, is appropriate and well-designed. By comparing the salt rejection and permeability flow of the two membrane systems, the study can provide valuable insights into the effectiveness of KDF media in reducing foul[1]ing caused by CaCO3 scaling. The explanation of how KDF media works to prevent the formation of mineral hardness scale by altering the morphology of the insoluble Ca and Mg carbonate and sulfate crystals and creating a redox environment is helpful in understanding the potential mechanism behind the effectiveness of KDF media as a pretreatment method. By con[1]trolling the formation of mineral scale and other contaminants, KDF media can potentially lead to improved efficiency of the RO membrane. Results suggest that KDF media can be an effective pretreatment method for reducing fouling caused by mineral scaling in RO systems. The potential mechanism behind the effectiveness of KDF media is explained, and the obser[1]vation that only a small number of KDF discs were degraded over the 40-hour period indicates that KDF media can be used for multiple cycles of RO operation, reducing the frequency of media replacement and associated operating costs. The finding
that the RO-KDF membrane remained healthy and efficient for 40 hours while fouling was observed in the RO system with[1]in 20 hours is also promising, as it indicates that the KDF media can effectively reduce membrane fouling caused by scaling, leading to improved efficiency and extended membrane life. However, further studies can explore the optimal conditions for using KDF media in RO systems to maximize its effectiveness in reducing fouling and extending the lifetime of RO mem[1]branes. Investigating the potential for KDF media to reduce fouling caused by other contaminants, such as organic matter or silica, would also be interesting

Authors: Borges Júlia Carolina Silva , Ribeiro Marina Navarro Verde Ubaldo , Marinho Simoni da Penha Lopes , Nunes Reginaldo Oliveira
Published: April 2023

A pesquisa discute o lugar onde estão situadas as crianças indígenas na Antropologia da Criança e como se constitui a relação com o brincar ao ar livre. Orientou-se pela pesquisa bibliográfica e pela narrativa como instrumento de coleta de informações. Ficaram evidentes a importância dada ao valor educativo da natureza como um pressuposto epistemológico comum nos diversos processos educacionais que se aplicam às infâncias indígenas brasileiras. Foi possível aferir o modo de vida ao qual as crianças estão atualmente submetidas (era digital). A ausência de elementos naturais, de expressões corporais e, a desconexão das crianças com a natureza tem gerado um mal-estar na contemporaneidade infantil, que os estudiosos classificam como Transtorno do Déficit de Natureza. É urgente uma (re) conexão das crianças com a natureza e as infâncias indígenas podem fornecer subsídios fundamentais para a elaboração de uma educação sensível que permita o bem-viver a todas as crianças.

FORMAÇÃO DOCENTE FRENTE AOS IMPERATIVOS DE FORMAÇÃO POR COMPETÊNCIAS DA BNCC
Authors: Techio Julia Patricia , Neitzel Odair
Published: April 2023

O presente artigo deriva do trabalho de investigação de mestrado, sendo uma revisão bibliográfica e documental em perspectiva hermenêutica e analítica, com o objetivo de discutir e refletir sobre o conceito de competência presente na Base Nacional Curricular Comum (BNCC). A investigação dialoga com um conjunto de documentos e referências, com ênfase nos escritos de Philippe Perrenoud. Resgata a trajetória de construção e aprovação da BNCC, documento que norteia e orienta o currículo escolar da educação básica brasileira e reconstrói alguns elementos políticos dos bastidores da construção da política. Estes acabaram inclinando a BNCC para uma perspectiva neoliberal e mercadológica, enfatizando a formação técnica e, consequentemente, enfraquecendo o lugar da docência. Assim, estabelece algumas reflexões a respeito das implicações do termo “competência”, “pedagogia das competências” para a escola e a formação de professores.  O caráter técnico-profissional da BNCC, de certo modo enfraquece a formação crítica e humana. Consequentemente descontrói o papel social e formativo da escola, que passa a ocupar o lugar de subordinação às exigências do mercado, sendo o professor um mero executor de tarefas.

O artigo retrata fatos e narrativas a despeito da identidade nacional do Brasil. Propõe perceber estrategias que unem saber e poder para construir uma governamentalidade (FOUCAULT, 1979) entre os anos iniciais até as cinco primeiras décadas do século XX. Com enfoque especial na territorialidade paranaense, descreve a eugenia como grande filosofia evolucionista adotada por pensadores no Brasil e no Paraná, como forma de conversação e, portanto, de instrumentalização política de enfrentar esta questão, dimensionando o biotipo humano do caboclo nacional e a miscigenação biológica e cultural com imigrante desejável e, no seu contraponto, o como a representação de indesejáveis excluiu sujeitos, habitos e modos de ser não congruentes com um modelo nacional desejado. A partir de fontes normativas, bibliografias, discursos políticos e publicações em meios oficiais como a Revista O ensino e Atas da Assembléia Legislativa, aponta-se os discursos de eugenia se desdobrando em representaçoes e projetos de assentamento de colonos e escolarização. Como resultado das reflexões, conclui-se que o desejo não não construiu seu objeto, mas disseminou visibilidades que interferiram no meio social do hinterland paranaense, como as Colonias, as sociedades científicas, as escolas.

American Female Missionary Victims of Epidemics
Authors: KUŞ Ayşegül , ALAN Gülbadi
Published: April 2023

Epidemics have always played an important role in human history and have deeply affected the individual, social and economic lives of states, communities and people. The communities located at the crossing point of civilizations and being on trade transition routes have been more affected by epidemics due to the intensity of interaction. This is probably why Anatolia has always faced epidemics from past to present. One of the time periods when these epidemics are intense is the process from 1820 to the end of the World War I. It is known that the American Board missionary organization was operating in the Ottoman lands during these epidemic times. For this reason, it is seen that the effects of the epidemic were voiced by missionaries, and even became the subject of American Board reports.

This study is about the female missionaries (married or single) who worked on behalf of the American Board organization, who left their country for an ideal, came to the Ottoman lands and lost their lives due to some epidemics. First of all, the subject of the study will be revealed through the information in the documents of the American Board, the articles in the Board’s publication called "The Missionary Herald". In the light of the aforementioned documents, the aim of the study is to both reveal the identities of the women missionaries who lost their lives in the Ottoman lands due to some epidemic diseases and also to relate which disease they died from, and thus to make some contributions to the literature.

Authors: Saikarthik Prodduturu , Reddy Vesam Harinath , Rafi Shaik Mahammed , Basha Valluru Wazeed , Padmakar Somanaboina
Published: April 2023

Objective: Vitiligo is a common depigmenting disorder with significant psychosocial consequences. Vitiligo has been associated with psychological disorders such as depression, low self-esteem, anxiety, and sexual dysfunction (SD). In recent years, there is an increase in the number of studies looking into the impact of vitiligo on sexual functions. This systematic review investigates the assessment and prevalence of SD in vitiligo patients. Materials and methods: We carried out a systematic search for observational studies on the prevalence of SD in vitiligo patients. The Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) guidelines were used to prepare this systematic review. We searched PubMed, Scopus, Google Scholar, and the Cochrane Library databases. Results: We observed 308 studies for screening. Finally, 12 studies that meet the eligibility criteria were included in this study. The prevalence of SD ranged from 2.7 to 82.0%. Most of the studies used the dermatology life quality index (DLQI) to assess SD. Our findings also show that vitiligo patients were more probably experience symptoms of depression and anxiety, one of the risk factors for SD. Conclusion: Psychological comorbidities are related to a high risk of SD in vitiligo patients. Further prospective longitudinal studies are required to investigate the causal factors for SD in vitiligo patients

Published: April 2023

Introduction: In half of the individuals with systemic lupus erythematosus (SLE), over the course of the disease, pulmonary involvement occurs frequently and is one of the parts in the array of presenting symptoms. But the published research and information on SLE have historically concentrated on renal, central nervous system (CNS), and dermatological manifestations, while the pulmonary effects of SLE have received very less attention. Objective: To know the extent and pattern of pulmonary involvement in SLE patients in a tertiary care hospital. Materials and methods: A cross-sectional observational study was conducted among 70 diagnosed SLE [who fulfilled the revised American College of Rheumatology (ACR) criteria for the classification of SLE] patients attending a tertiary care center. Seventy diagnosed SLE patients who met the updated ACR criteria for the classification of SLE and were enrolled in a tertiary care facility in West Bengal participated in a cross-sectional observational study. After informed consent, clinical examinations, general survey, respiratory examination, cardiovascular examination, and relevant investigations [chest X-ray, pulmonary function test, echocardiography and electrocardiography, and high-resolution computed tomography (HRCT)/chest computed tomography (CT) scan] were performed. Results: The majority of the study subjects belonged to the 21–30 years of age-group (45.7%) and were females. Most of the study subjects were treatment-naïve as they were newly diagnosed. Among the chief presenting complaints, the most common was cough followed by dyspnea and pleuritic chest pain. Chest X-rays showed pleural pathology in 37% of study subjects and pulmonary function tests were found to have a restrictive pattern in 4.3%. Echocardiography documented that 19.6% had pulmonary artery hypertension. HRCT revealed that 19.4% of subjects had definitive findings of interstitial lung diseases (ILD). Conclusion: A substantial contributor to morbidity and death, SLE is a potentially fatal, commonly debilitating autoimmune illness with pulmonary symptoms. Cough was the most common presenting complaint, and the most common radiological abnormality detected was pleural effusion. Spirometry revealed, as expected, a restrictive pattern in most of the cases. Around 29% of cases revealed features suggestive of or confirmatory evidence for intestinal lung disease. As a whole, the prevalence of lung involvement in SLE in the study was 67%. But this being a study with only 70 participants, a further longitudinal is recommended to study disease activity correlation with the incidence of early pulmonary involvement in SLE disease course.

Published: April 2023

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection started in Wuhan, China, and spread to the rest of the world to become a pandemic affecting over 385 million people throughout the world to date. Coronavirus disease 2019 (COVID-19) is primarily started as a respiratory tract infection. Recent studies indicate that it should be regarded as a systemic disease involving multiple systems including the hematopoietic system. Complete blood count and its parameters are important investigative tools in its prognosis. However, very few studies highlight the importance of peripheral blood cell morphology in this disease. Aim: To study the hematological parameters (complete blood count and peripheral blood film) of COVID-19-positive patients and to compare the hematological parameters of those admitted in intensive care units (ICUs) with those admitted in non-ICUs of the hospitals. Materials and methods: This retrospective study was carried out at a COVID-19 dedicated tertiary care center over a period of 3 months from July 2020 to September 2020. In our study, all 79 patients had complete blood counts performed at the time of admission. Complete blood count was repeated during the hospital stay for all severe cases. The data which provided information on the age and gender of each patient were obtained from the Laboratory Information System (LIS) of the hospital. Results: The mean age of our study group was 46.05 years. Out of 79 cases, lymphopenia was seen in 16.5% with five patients presenting with severe lymphopenia (<0.5 × 109 /L). All the patients that required ICU care presented with moderate to severe lymphopenia. The patients in the ICU setting showed significant neutrophilia (mean 14.16 × 109 /L) on follow-up complete blood count. Thrombocytopenia was observed in 35.3% of cases. It was observed that the mean neutrophil– lymphocyte ratio was higher in ICU admitted patients as compared to the non-ICU admitted patients. Among the ICU patients, 80% showed a neutrophil–lymphocyte ratio above the baseline cutoff (3.1). A wide array of morphological changes were observed in the peripheral blood smear including toxic-like granules in neutrophils, fetus-like C-shaped nucleus, lymphoplasmacytoid cells, bizarre cells, and apoptotic cells. Conclusion: The study highlights that at the time of admission older age, decreased lymphocyte count, and raised neutrophil–lymphocyte ratio were closely associated with ICU admissions. Also, the morphological changes in peripheral blood film reveal atypical changes predominantly in the white blood cell (WBC) lineage

Authors: Rajendran Bhuvaneshwari , N Sridhar , Ramkumar Gayathri
Published: April 2023

Background: Coronavirus disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), led to one of the deadliest pandemics faced by mankind. The typical manifestation of COVID-19 infection includes respiratory distress. However, we know that the characteristic immunologic pathways of SARS-CoV-2 infection inflict systemic disorders and eventually multi-organ dysfunction in a subgroup of patients. The disease can affect both central and peripheral nervous systems. Objective: The aim of our study was to describe the wide spectrum of neurological manifestations associated with SARS-CoV-2 infection and its clinical characteristics. Materials and methods: We conducted a retrospective, single-center, observational study to analyze neurologic manifestations associated with COVID-19 patients from May 2020 to September 2021 at a tertiary care hospital in Chennai, South India. Results: A total of 80 COVID-19-confirmed patients with neurological disorders were included in our study. The most reported neurological manifestation was altered sensorium (29.6%). Twenty-nine (34.4%) patients were on noninvasive ventilation and a significant number of patients (22) (26.8%) needed invasive ventilation. The mortality rate was 34.1% and the large vessel involvement in stroke patients was 10%. Conclusion: Neurological issues in COVID-19 patients are relatively common and have the propensity to manifest later as post-acute COVID-19 syndrome.

Published: April 2023

Introduction: The hemodynamic adjustments during pregnancy play a pivotal role in sustaining the gestation, however, its clinical connotation on midterm renal hyperfiltration and its consequence on maternal and fetal outcomes need a greater appraisal. The present retrospective study looked into the midterm estimated glomerular filtration rate (eGFR) among pregnant females without overt pieces of evidence of chronic kidney disease (CKD) as a surrogate marker for midterm hyperfiltration and its implication on maternal and fetal outcomes. Materials and methods: All pregnancies among females aged 18–50 years with available pregestational baseline serum creatinine were included in the study. Maternal renal hyperfiltration was expressed as the highest eGFR, using the creatinine clearance method. Its association with adverse maternal and fetal outcomes was assessed. Results: A total of 1,045 pregnancies were assessed during the study. According to midterm eGFR, among them, 65% of pregnancies showed midterm eGFR between 120 and 150, however, 4.3% of pregnancies had values more than 150 mL/min per 1.73 m2 . The risk of poor pregnancy outcome was observed for eGFR levels below and above the reference level of 120–150 mL/min per 1.73 m2 (1.97 for values ≥150 mL/min per 1.73 m2 , and 1.72 for 90–120 mL/min per 1.73 m2 ). Pregnancies with eGFR between 60 and 90 mL/min per 1.73 m2 had odds ratios (ORs) of 5.64. Conclusion: A distinctive relationship was observed between the midterm eGFR and adverse pregnancy outcomes with the best outcomes for midterm eGFR levels between 120 and 150 mL/min per 1.73 m2 . Despite no apparent functional renal deterioration, a poor maternal hyperfiltration response may play a crucial impact on poor pregnancy outcomes.

Laser powder bed fusion (LPBF), a metal additive manufacturing technique, was conducted on feedstock-modified 316L stainless steel (316L) powder produced by ball-milling of commercial 316L and 1 wt% additive (cerium oxide—CeO2, lanthanum (III) nitrate hexahydrate—La(NO3)3·6H2O, and chromium nitride—CrN). The feedstock-modified LPBF-316L specimens were sensitized at 675°C for 24 h, and the influence of additives on intergranular corrosion (IGC) was investigated following ASTM G108-94 and A262-14 standards. The LPBF-316L with La(NO3)3·6H2O showed higher IGC resistance. The microstructure of the LPBF specimen was investigated and correlated to understand the improved IGC resistance of LPBF-316L with La(NO3)3·6H2O additive.

Erosion-corrosion behavior of high-speed steel (HSS) and titanium aluminum nitride (TiAlN) coating were investigated under different flow conditions in simulated seawater. On the front side (facing toward the direction of water flow), there was a negligible failure of the TiAlN coating, but clear marks of erosion-corrosion on the HSS. Notwithstanding, unexpected failure features were identified on the back side (back against the direction of water flow) on both specimens because the high-velocity water flow was localized at the edge and the center was high in turbulence. For the HSS, there was dominant corrosion in the center and dominant erosion at the edge. For the TiAlN/HSS coating, the dense and layered structure retards the propagation of surface cracks as the major failure into the bulk and instead promotes layer-by-layer spallation. Additionally, visible “flow marks” were observed on both specimens and can be explained by the flow-accelerated-corrosion.

Introduction: Oxidative stress (OS) results from the overproduction of reactive oxygen species (ROS), being responsible for the development of numerous pathologies. Resveratrol (3,5,4’- trihydroxystilbene) is a naturally occurring antioxidant, produced by a wide variety of fruit and plant species, in response to several stimuli. Due to its antioxidant, anti-inflammatory, cardio, and neuroprotective properties, this polyphenol has shown great interest in recent years. Objective: To understand the role of resveratrol in enzymatic antioxidant defenses and vascular function, but also in decreasing inflammation. Material and Methods: 27 healthy students, aged 18 - 22 years, were randomized into control (CG) and experimental (EG) groups, and submitted to placebo and resveratrol supplementation, respectively, for 30 consecutive days. In these participants, laboratory evaluation of glutathione peroxidase (GPx) and reductase (GluRed) activity by spectrophotometry, and serum levels of endothelin 1 (ET-1), tumor necrosis factor-alpha (TNF- α), and interleukin-6 (IL-6) by slot blot were performed, before (T0) and after supplementation (T1). Results: Evaluating GPx activity at T1, higher values were observed in the EG (p = 0.005). Regarding GluRed, both groups demonstrated a tendency to increase enzyme activity at T1. However, significant results were only observed in CG (p = 0.004). In the remaining parameters evaluated, no significant differences were observed. Conclusions: Supplementation with resveratrol may be effective in reducing OS by increasing the activity of endogenous antioxidant enzymes. Yet, it was unable to prove its role as a cardioprotective and anti-inflammatory agent.

Introduction

The presence of chronic obstructive pulmonary disease (COPD) can impact the management of acute myocardial infarction (AMI) and is associated with higher mortality. Few studies addressed COPD impact on heart failure hospitalisations (HFHs) in AMI survivors.

Material and methods

Adult survivors of an AMI between January and June 2014 were identified from the US Nationwide Readmissions Database. The impact of COPD on HFH within 6 months, fatal HFH and the composite of in-hospital HF or 6-month HFH was studied.

Results

Of 237,549 AMI survivors, patients with COPD (17.5%) were older, more likely female, had a higher prevalence of cardiac comorbidities and a lower coronary revascularization rate. In-hospital HF was more frequent in patients with COPD (47.0% vs. 25.4%; p < 0.001). HFH within 6 months occured in 12,934 (5.4%) patients, at a 114% higher rate in patients with COPD (9.4% vs. 4.6%, OR = 2.14, 95% CI : 2.01–2.29; p < 0.001), which was attenuated to a 39% higher adjusted risk (OR = 1.39, 95% CI: 1.30–1.49). Findings were consistent across subgroups of age, AMI type, and major HF risk factors. Mortality during a HFH (5.7% vs. 4.2%, p < 0.001) and the rate of the composite HF outcome (49.0% vs. 26.9%, p < 0.001) were significantly higher in patients with COPD.

Conclusions

COPD was present in 1 of 6 AMI survivors and was associated with worse HF related outcomes. The increased HFH rate in COPD patients was consistent across several clinically relevant subgroups and these findings highlight the need for optimal in-hospital and post-discharge management of these higher-risk patients.

This experiment was conducted to evaluate the physical properties, chemical quality, and digestibility of the ammoniated Bambara groundnut (Vigna subterranea) shell as ruminant feed. Bambara groundnut shell (BGS) were collected, ground with a grinder machine, afterward added 0, 3 and 5 (% DM) urea levels into 500 g of sample. Samples were mixed until homogeneous, then put into plastic bottles, after that stored for 7 and 14 days. Opened, dried in the oven at 650C for 48 hours and ground. A completely randomized design (CRD) was used with 5 treatments of BGS ammoniation (T0= control, T1= BGS + 3% urea and 7 days storage, T2= BGS +5% urea and 7 days storage, T3= BGS + 3% urea and 14 days storage, and T4= BGS + 5% urea and 14 days storage time), 4 replications each. The result of this study showed that the increase of urea level and days storage time, can decrease crude fiber, neutral detergent fiber, acid detergent fiber, and hemicellulose contents of all samples (P<0.05) and increase the value of bulk density, tapped density, in vitro dry matter digestibility and in vitro organic matter digestibility in comparison to untreated samples (P<0.05). It was concluded that the T4 was the best treatment. The BGS ammoniated with 5% urea for a period 14 days of storage causes the lowest value of crude fiber, neutral detergent fiber, acid detergent fiber, and hemicellulose, and also causes the highest value of bulk density, tapped density, crude protein, in vitro dry matter digestibility and in vitro organic matter.

This study aimed at evaluating the fermention levels of pearl millet [Pennisetum Glaucum (L.) R. Br] stovers silage during storage based on pH evolution. A completely randomized experimental design in a 6×2×2 factorial scheme with three replications for each treatment was used to evaluate three factors (6 cultivars, 2 different cutting stages, and with or without salt addition to the cultivars). The silages were prepared in plastic bags and stored for 60 days at room temperature. The results revealed that the pH values of the treatments were significantly (P < 0.05) higher on the first day than in the other periods and a rapid drop in pH, with significant differences (P < 0.05), to levels below 4 was obtained on the third day of storage for the majority of local Sadoré and Siaka Millet silages (Niger). Four types of pH evolution were recorded and the variation was statistical significant among cultivars. Also, analysis of the relationships between pH, chemical composition parameters and In Vitro Digestibiliy of Organic Matter (IVDOM) showed that increasing pH values were associated with increasing Dry Matter content of stovers before silage (DM_BE), Dry Matter content of silages (DM_S), Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF), Acid Detergent Lignin (ADL) values and decreasing Crude Protein (CP), Metabolizable Energy (ME), IVOMD, and Ash values. However, the pH values obtained for all silages showed that all the millet stovers used were suitable for silage. At the maturity stage, it is thus possible to use the grain for human consumption and to ensile the stovers for animal feed. This study also shows that monitoring the pH in the silo makes it possible to evaluate the quality of the fermentations to avoid losses on the farms.
