Authors: Zakarka Mindaugas , Skuodis Šarūnas , Mackevičius Rimantas , Sližytė Danutė
Published: December 2021

This research work represents updated results of cohesive soil strength improvement with mineral wool fly ash. In the investigations, these materials were used: Portland cement CEM I 42.5 R, fly ash obtained from a mineral wool production process, sand and clay. Mixtures were prepared as follows: dry mixing of Portland cement and fly ash; dry mixing of sand and clay; adding water into Portland cement and fly ash; adding sand and clay mixture into already prepared Portland cement and fly ash suspension. The content of fly ash replacing Portland cement varied from 0% to 40%, and the content of sand mixture varied from 20% to 60%. After 24 hours, investigated samples were taken out from cylinder forms and kept in a desiccator with a humidity of 90% and at 20 °C temperature. Uniaxial compressive strength of the samples was determined after 548 days and compared to previous research results obtained after 7, 28 and 183 days. The most predictable compressive strength is for samples, which composition is 100% cement and 0% fly ash. In these samples, the highest compressive strength was obtained, comparing them to the other investigated samples. Compressive strength change is minimal for samples with a 10–30% amount of fly ash. The most significant decrease in compressive strength was obtained for samples with a 40% fly ash after 183 days. Nonetheless, the compressive strength of these samples increased after 548 days and is almost the same as for samples with 100% Portland cement.
Eliminating the Influence of Axle Parameters in Influence Line Identification
Authors: Zhang Qingqing , Liu Qianlong , Dai Li , Liu Qiang
Published: December 2021

Accurate and rapid acquisition of the strain influence line of continuous beam plays a positive role in promoting the wide application of structural health monitoring. The structural response obtained from the sensors is used to estimate the strain influence line. However, most estimation methods ignore the influence of axle parameters on the structural response, resulting in a large error in identifying the strain influence line. This paper presents a method for eliminating the influence of axle parameters of moving vehicles on strain responses to estimate the strain influence line of continuous beams based on the long-gauge strain sensing technology. By analysing the mechanical characteristics of the multi-span continuous beam, a theoretical strain influence line expression is first established to obtain the strain influence line of the continuous beam accurately. The structural response only caused by axle weight, obtained by eliminating the influence of axle parameters, is then estimated for calibrating the theoretical strain influence line. Finally, different lane tests are also considered to solve the influence of different transverse position relations on the proposed method between the monitoring unit and the lane. Finally, numerical simulations are adopted to illustrate the effectiveness of the proposed identification method by simulating the strain time histories induced by a multi-axle vehicle. A field test also demonstrates the validity and feasibility of this method.
TENDENCY OF GLOBAL CAPACITY DEVELOPMENT OF RENEWABLE ENERGY SOURCES IN THE WORLD IN THE LAST TEN YEARS
Authors: Karabegović Isak
Published: December 2021

It is well-known that, in the past decades, the burning of fossil fuels was identified as the major cause of climate change. Climate change mitigation is becoming a central concern of global society. Limiting global warming to below 2 °C above the temperature of the pre-industrial period is the key to preserving global ecosystems and providing a secure basis for human activities, as well as reducing excessive environmental change. The ambitions increased at an accelerated pace with a dramatic expansion of net zero-emission targets. Increasing pressure from citizens and society has forced countries to intensify their climate plans, while the private sector has bought a record amount of renewable energy. An energy system based on fossil fuels must be replaced by renewable energy with low carbon emissions with improved energy efficiency. That applies to all consumers of fossil energy: cities, villages, building sectors, industry, transport, agriculture, and forestry. The paper explores and presents the strategy of energy development of renewable energy sources in the world. The application of new technologies that have led to developing renewable energy sources is presented in detail: wind energy, solar energy, small hydropower plants, biomass, and their increase in the total share of energy production, i.e., reduced fossil fuel use in energy production. Investments in new technologies used in renewable energy sources have led to increases in employment worldwide. Analysis of the trend of increased energy production from RES (Renewable Energy Sources) with investment plans, the employment rate for each energy source, and the development of renewable energy sources in the coming period are provided.
ARTIFICIAL INTELLIGENCE AND NATURE-INSPIRED OPTIMIZATION ON INTEGRATIVE CAPACITY OF RENEWABLE ENERGY IN THE WESTERN BALKAN
Authors: Stevović Ivan , Kirin Snežana , Bozić Ivan
Published: December 2021

Two artificial intelligence models for the integration of renewable energy sources are developed within this research to contribute to the European Green Plan realization. The review of renewable energy natural potential, on one hand, and installed capacity, on the other hand, in the Western Balkans and twenty-eight European countries is done within this research, as well as emissions. The analyses show that the European countries, sometimes even with lower natural potential in renewables, have installed much more renewable capacities than the Balkans countries with much higher natural potential. According to this, the first artificial intelligence model is developed based on multi-criteria linear regression analysis. This model relies on the correlation between the relevant regressors, i.e. relevant input variables for twenty-eight European countries and the same regressors for a particular Balkans country. Its goal is to find the maximum possible integrative renewable capacity in a Balkans’s country within the real socio-economic environment. The second artificial intelligence model is developed based on multi-criteria evolution genetic algorithms. Its goal is to find the maximum possible integrative renewable capacity within a real electric power system. Nature-inspired optimization is applied. From the framework of a given large number of generations, technical combinations of the degree of renewable energy sources integration, the best populations, i.e. combinations are selected. As nature selects from many generations and allows the best to survive and punishes the „weakˮ, in our case, „weak” combinations are those failing to meet the given conditions and limitations of the real electric power system. A new methodology is offered. Theoretical general formulas are given for both models. Developed models are tested on a numerical experiment of solar energy integration in the Serbia case study. Analyses of sensitivity prove that both models are applicable for all renewable energy sources and countries or regions.

Authors: Shuiskaya Yuliya Viktorovna , Murzina Ol'ga Viktorovna , Karpov Ernest Sergeevich
Published: December 2021

The object of this research is the text component of Internet meme as a signifier of special type. The subject of this research is the peculiarities of text captions to the images posted in the Russian-speaking and English-speaking segments of the Internet. The authors dwell on such aspects as the syntactic, theme-rhematic, and orthographic peculiarities of the text component of Internet memes. Special attention is given to the problem of intentional misspellings in text captions. In most cases, namely the text actualizes the image; the memes usually involve film stills, drawings, and photo images, and text captions turn these images into the relevant Internet memes. The main conclusions lies in determination of the peculiarities of the text part of creolized Internet memes on all linguistic levels. Due to the specificities of Internet memes, the texts usually represent short sentences. The syntactic structure of used phrases often resembles a marked construction, and in a number of instances with intentional misspellings. The novelty of this research lies in the analysis of Internet memes from the perspective of linguistics. Although there are Russian and foreign research dedicated to semiotic and communicative components of the Internet memes, as well as their evolution and transformations, the analysis of linguistic component is carried out for the first time.

Published: December 2021

This paper is based on the famous log-periodic power law model (LPPL) in financial physics to warn of the collapse of China's Shanghai Composite Index and GEM Index in June 2015. In view of the existing research using the LPPL model to warn of market crash, only the historical trading data of the market are considered. For the first time, investor sentiment factors are incorporated into the modeling process of LPPL model to improve the early warning effect of LPPL model. Using the text mining technology combined with semantic analysis methods to grasp the financial media's stock evaluation report for word frequency statistics, in order to build the medium sentiment index. The further modified expression of the crash probability function in the LPPL model is represented as a function of historical trading data and medium sentiment, and thus constructing an LPPL-MS combination model to warn of stock market crash. The empirical results show that the LPPL-MS combination model constructed in this paper has higher warning accuracy than the LPL model, and its prediction crash time is closer to the actual crash time of the Shanghai Index and GEM Index, and its fitting results have passed the relevant test.

Published: December 2021

Introduction: Treatment for Low Back Pain (LBP) due to Prolapsed Intervertebral Disc (PIVD) includes conservative management, Epidural Steroid Injection (ESI), and surgery. Transforaminal Epidural Steroid Injection (TFESI) is a more recently described approach. All corticosteroid preparations used for TFESI are particulate except dexamethasone and betamethasone sodium phosphate. But while comparing methylprednisolone with dexamethasone, the latter has more potent anti-inflammatory action with least likelihood of causing embolic events and is also less expensive. Aim: To compare the efficacy of transforaminal epidural injection of dexamethasone and methylprednisolone in reducing LBP and disability in prolapsed lumbar intervertebral disc amongst the indigenous population of Manipur, India. Materials and Methods: This was a randomised controlled study on 80 patients with PIVD attending Outpatient Department (OPD) at physical medicine and rehabilitation was conducted from September 2016 to August 2018. A single dose of lumbar TFESI with dexamethasone in the study group and methylprednisolone in the control were given under C-arm guidance. The outcome variables Visual Analog Scale (VAS) for pain and Oswestry Disability Index (ODI) for function were measured at one week, one month and six months. Statistical tests like t-test, Chi-square test were used for intra group and inter group analysis. Results: In the total sample of 80 patients, 40 (15 males and 25 females, mean age: 38.28±8.55 years) were categorised as Dexamethasone patients and 40 (17 males and 23 females; mean age: 39.28±7.80 years) as methylprednisolone patients, there were significant improvement in mean score of VAS and ODI in both the groups (p-value <0.05). At six months, both treatment groups maintained initial observed improvements, with no significant differences between groups on the VAS {95% Confidence Interval (CI), -0.02 to 0.4; p-value=0.07} and ODI (95% CI,-0.21 to 3.43; p-value=0.08). Conclusion: Non-particulate steroid dexamethasone was similar in efficacy to the particulate steroid methylprednisolone in lumbar TFESI. However, in view of the greater safety profile of dexamethasone, it is suggested that dexamethasone may be used as the preferred agent in lumbar TFESI.

Published: December 2021

Introduction: Peripheral intravenous therapy is one of the most frequently used therapeutic interventions in the acute care setting. Paediatric intravenous cannulation is a fundamental part of medication and practised in almost every health care setting. Intravenous therapy is used to treat a wide variety of paediatric conditions. Although most hospitalised children receive intravenous (i.v.) therapy daily, treatment extends beyond this population to Out Patient (OP) settings, long term care and home care for the infusion of fluids, blood products, and medications. Aim: To assess the effectiveness of planned teaching program on knowledge and practice regarding intravenous therapy among paediatric nurses. Materials and Methods: The present pre-experimental, quantitative, non randomised, one group pre and post test design study was conducted in Paediatric Ward, Paediatric Intensive Care Unit (PICU) and Neonatal Intensive Care Unit (NICU) of ‘G’ block, Sri Ramachandra Hospital (SRH), Porur, Chennai, Tamil Nadu, India from 11th July 2016 to 20th August 2016. Self administered questionnaire and observational checklist was used to collect data about knowledge and practice respectively. Non probability purposive sampling technique was used to select the 30 staff nurses working in the paediatric department with less than one year of experience. Results: The difference between the mean post-test knowledge score (M=16.20, SD=2.041) and pretest knowledge score (M=7.43, SD=2.254) of paediatric staff nurses was highly significant (p-value <0.001) and the computed t-value was t=26.7. The difference between the mean post-test practice score (M=15.13, SD=2.063) and pretest mean practice score (M=10.70, SD=2.380) was also highly significant (p-value <0.001) and the computed t-value was t=8.215. Conclusion: The present study shows that there was a significant difference in the mean scores of knowledge and practice between pretest and post-test after the planned teaching program intervention at the level of paediatric nurses (p<0.001). So planned teaching program was effective on knowledge and practice regarding intravenous therapy among paediatric staff nurses.

Published: December 2021

Thyroglossal duct cysts are most commonly occurring congentinal midline swellling of the neck. Usually carcinomas in thyroglossal duct cysts is extremely rare, commonly known as papillary carcinomas. However, the diagnosis is only made postoperatively after excision of the cyst. Although the Sistrunk procedure is often regarded as adequate but controversies exist, the need for thyroidectomy is based on histopathological findings. This is a case report of 43-year-old male presenting with swelling in the midline of the neck for one year. On examination, a cystic swelling was present in the midline of the anterior aspect of the neck. Ultrasonography (USG) neck revealed heteroechoic cystic lesion with solid component and microcalcifications present within the cyst suggestive of thyroglossal duct cyst probably neoplastic. The mass was surgically excised and sent for histopathological examination and reported as thyroglossal duct cyst with papillary carcinoma of thyroid. Appropriate history, clinical examination and investigation leads to the correct diagnosis and treatment. Incomplete removal of the mass leads to recurrence. Histopathological examination is a must postoperatively. The patient is still on follow-up and no recurrence have been noted.

The COVID-19 pandemic has overtaken the lives of millions around the world. While this has helped the virtual technology make advances, it has restricted social beings to their households for over a year. It is only natural to want a change from the boring view of the house and the Olympics being conducted itself is one of the global feats that showcase the resilience of people to strive forward without letting the virus command their lives. With frustration predominating the powerful emotions, people are slowly beginning to resign to the acceptance of the dangers of the deadly virus with its constantly evolving nature. The latest delta variant is the most dangerous one so far. Despite the extensive research being carried out by various diligent scientists, the ultimate cure has yet to be found. Until then, our best hope is the vaccination and following the guidelines of social distancing and protection with masks. These are simple, common-sense rules that need the least amount of instruction yet people seem to find it hard to adhere to these new norms. There is increasing hesitancy and fear due to lack of research but if people can be brave enough to weather the perils of the virus at a universal scale, they should be able to brave the tiny prick as well.
Utilisation of Supplementary Nutrition Service at Anganwadi Centres in a Block of Ganjam District, Odisha: A Cross-sectional Study
Authors: Sabat Smaranita , Karmee Nivedita
Published: December 2021

Introduction: In India, the Integrated Child Development Services (ICDS) scheme provides a package of services to different groups of the target population. The Anganwadi Centre (AWC) is the focal point for delivery of these services. At AWCs, supplementary food is provided to children below six years, adolescent girls, pregnant women and lactating mothers. Aim: To assess the pattern of utilisation of supplementary nutrition by the beneficiaries and to explore the factors leading to non utilisation of supplementary nutrition. Materials and Methods: This was a cross-sectional study conducted from October 2016 to October 2018 in AWCs in Ganjam district, Odisha, India. Multistage random sampling was used to select the AWCs. By using table of random numbers, 24 AWCs were selected. From each AWC, 12 beneficiaries were selected randomly. So a total of 288 beneficiaries were selected. Out of 288 beneficiaries, 240 beneficiaries were eligible for supplementary nutrition. Rates and proportions were calculated. The Chi-square test was used for testing association between variables. Results: All the AWCs were providing supplementary food as per menu chart and were using standard measure for distribution of raw food. Supplementary food was consumed by 188 (78.3%) beneficiaries. The reason given by most of the respondents {28 (53.8%)} for non utilisation of supplementary nutrition was that they did not like the taste of the food. A statistically significant association was found between utilisation of supplementary nutrition and factors like education, socio-economic status and occupation of women. Conclusion: Although supplementary nutrition was provided by all the AWCs, it was not consumed by some beneficiaries due to lack of variety, taste and bad quality of food. The Take Home Ration (THR) was shared among the family members resulting in dilution of the service.

Стереосъемка взволнованной водной поверхности — один из наиболее результативных инструментов дистанционной оценки характеристик взволнованной поверхности. Как правило, этот метод реализуется с палуб стационарных океанографических платформ или береговых сооружений посредством двух или более откалиброванных камер. От качества калибровки камер, традиционно реализуемой путем фотосъемки тест-объекта (шахматной доски) с разных ракурсов, напрямую зависит точность восстанавливаемой по стереопарам топографии объекта. При отлаженной процедуре восстановления морской поверхности по данным калиброванной стереосистемы, значительный интерес представляет получение данных с близкой точностью с помощью некалиброванных систем. Исследованию этого вопроса на примере судовой стереосъемки в Атлантике посвящена настоящая работа. Рассматривается процесс обработки изображений с некалиброванных камер, приводятся результаты восстановления рельефов морской поверхности и пространственных спектров ветровых волн при нескольких скоростях ветра, а также анализируется практическая применимость некалиброванных систем.

Published: December 2021

Немногочисленные сохранившиеся сведения о наводнении Невы 5 (16) ноября 1721 г. свидетельствуют о его катастрофическом характере. О наводнении писали Ф.Х. Вебер, Ф.В. Берхгольц, Анри де Лави, Н.Н. Головин и др. Высота потопа была оценена И.Г. Лейтманом и приведена в совместной с Л. Эйлером статье 1729 г. Однако известно, что целый ряд приемов обращения с выборками из уровнемерных наблюдений не выдерживает критики с современных обсерваторских и метрологических позиций. Так, негативное отношение А.И. Мордухая-Болтовского к ряду наводнений Невы И.Г. Лейтмана, дополненному В.Л. Крафтом событиями 1723 и 1725 гг., не поддается разумному объяснению. Это обвинение формально «оправдывало» расчленение ряда различными нивелирными поправками, определенными в XX в. в процессе редуцирования к нулю Кронштадтского футштока.

Приведены данные о движении сейсмоактивных участков земной коры в районе черноморского побережья по данным GPS-измерений, которые непрерывно выполнялись от 6 до 9 лет в региональной сети спутниковых геодинамических пунктов (СГП) GPS/ГЛОНАСС. Сеть включает в себя два сегмента, охватывающих северо-западную и юго-восточную части Азово-Черноморского побережья Краснодарского края. Определены фоновые значения деформаций земной коры, необходимые для инструментальной оценки напряженного состояния геофизической среды в процессе подготовки землетрясений. Наблюдениями на СГП восточного сегмента сети (Сочи, Адлер, Лесное и Эсто-Садок, расположенных в пределах Пшехско-Адлерской поперечной флексурно-разломной зоны) подтверждена геодинамическая активность наиболее сейсмически опасного Мзымтинского разлома от района Красной Поляны до его сопряжения с Пластунским разломом. GPS-наблюдениями и данными сейсмических исследований установлена геодинамическая активность района нижней долины р. Мзымты, покрытого серией разломов и зонами трещиноватости, ограниченными субширотными разломами, определяющими главную геотектоническую зональность Кавказа, с возможным продолжением геодинамической активности этого района в море до пересечения с Восточно-Черноморской зоной разрывных нарушений. В результате синхронных GPS-измерений на СГП Эсто-Садок и временном СГП Аибга, размещенных с разницей высот в 1700 м, установлен разноблоковый характер движений на этих пунктах и подтвержден левосторонний сдвиг вдоль Мзымтинского разлома. На западе Туапсинско-Сочинской сейсмоактивной зоны наблюдениями на временном СГП Чемитоквадже выявлена геодинамическая активность разломов поперечного (антикавказского) направления. Мониторинг сейсмогеодинамической активности этих разломов требует установки постоянных СГП в районе Туапсе, пос. Чемитоквадже и пос. Головинка. Более длительный период непрерывных наблюдений на пунктах GPS (25–30 лет) даст возможность обнаружить смену геодинамических периодов сжатия и растяжения земной коры, что важно знать для оценки геодинамической обстановки при строительстве долговременных объектов повышенной ответственности и определения прогнозных признаков сейсмической опасности.

Цель исследования: выделить критерии и разработать алгоритм оценки степени опасности очагов туберкулеза (ТБ) с использованием авторской компьютерной программы. Материалы и методы. База данных компьютерной «Программы учета и мониторинга очагов ТБ на территории» содержит сведения о 110 взрослых больных ТБ, 17 больных ТБ детях, 95 контактных лицах и 169 детях с положительными иммунологическими тестами на ТБ, зарегистрированных на территории фтизиатрического участка г. Ярославля в 2011–2018 гг. Работа осуществлялась в онлайн режиме с одномоментной проекцией на электронную карту территории данных по взрослым и детям. Результаты. Выделены и изучены 66 зон территориального риска по ТБ: 44 (66,7%) зоны с неблагополучной ситуацией по ТБ у взрослых; 7 (10,6%) зон с неблагополучной ситуацией по ТБ у детей без выявленного источника инфекции; 15 (22,7%) зон социального риска, где отсутствовали зарегистрированные больные ТБ. Проведена оценка изменений локальной эпидситуации в отмеченных зонах неблагополучия. Определены критерии степени опасности территориальных очагов ТБ: наличие на территории домов, объединенных общим двором: двух и более больных ТБ – бактериовыделителей; больного – бактериовыделителя с социально-неблагополучным статусом; наличие отягощающих факторов; очаг смерти в сочетании с еще одним заболевшим ТБ, независимо от бактериовыделения; больной – бактериовыделитель, уклоняющийся от лечения; два и более ребенка с положительными иммунологическими тестами на ТБ и/или один и более больных ТБ детей без взрослого источника инфекции или с одним больным ТБ, независимо от бактериовыделения; больной – бактериовыделитель с лекарственной устойчивостью возбудителя. Выделены очаги высокого (один критерий, 55,6%) и критического (два критерия, 44,4%) уровня опасности. Программа автоматически оценивает степень опасности эпидочагов для проживающих на данной территории. Заключение. Разработанная программа позволяет анализировать эпидситуацию в пределах конкретной территории с выделением зон риска по ТБ, обоснованием высокой степени опасности территориальных контактов для взрослых и детей с необходимостью длительного наблюдения и проведения профилактики в течение 3–4 лет. Эпидемиология становится персонифицированной и управляемой при выполнении направленных противотуберкулезных мероприятий.

Саркоидоз является системным воспалительным заболеванием неизвестной природы и характеризуется образованием в различных органах и тканях эпителиоидно-клеточных гранулем без казеозного некроза. Историческая связь между двумя нозологиями – саркоидозом и туберкулезом (ТБ) обусловлена не только существовавшим ранее предположением об этиологической общности этих заболеваний, но и множеством клинических, иммунологических и рентгеноморфологических параллелей. Дифференциальная диагностика этих двух системных гранулематозов, несмотря на значимые достижения медицинской науки, представляется сложной страницей современной пульмонологии и фтизиатрии. Представленный клинический случай иллюстрирует длинный путь к верному диагнозу у 20-летнего пациента, который до верификации диагноза «саркоидоз» получал противотуберкулезную химиотерапию по V режиму.

However, the incidence of otitis media following laryngectomy and the mechanism remain unclear. This study aimed to identify the incidence and risk factors of otitis media after total laryngectomy.Subjects and Methods: This retrospective cohort study assessed 77 patients who underwent total laryngectomy from 2010 to 2020 in a tertiary referral center. Serial imaging studies (computed tomography [CT], magnetic resonance imaging, and positron emission tomography-CT) were used to assess otitis media.Results: The study enrolled 58 patients (mean age, 67.0±7.7 years; male, 56 [96.6%]); nine (15.5%) underwent a gastrostomy tube (four preoperatively and five postoperatively). Otitis media was confirmed in seven (12.1%) patients. Gastrostomy tube insertion was the only significant risk factor for otitis media (p=0.012). Of the nine patients who underwent gastrostomy tube insertion, four developed otitis media; all four had the procedure after laryngectomy.Conclusions: This study found an increased incidence of otitis media after total laryngectomy. Swallowing difficulties likely contribute to otitis media as it occurred more frequently in patients requiring postoperative gastrostomy tube insertion.

Published: December 2021

The estimated projected data regarding demand and supply of feed and fodder shows13.20% and 18.43% deficit between demand and supply of dry and green fodder to livestock, respectively. Shortage of land for cultivation of fodders and increased human as well as livestock population has led to heavy competition for food grains that necessitates using the crop residues for the feeding of livestock. These crop residues are rich in fibre and low in other nutrients; they also have low palatability and digestibility. The best way to efficiently utilize the crop residues is to prepare complete feeds from pretreated crop residues + concentrates mixture. Pretreatment of crop residues increases digestibility by increasing rate of delignification, increasing enzymatic hydrolysis of cellulose, hemicelluloses and thus increasing the glucose yield.  The complete feed is a quantitative mixture of all dietary ingredients to provide the specific nutrient requirement for various physiological functions of livestock. Crop residue-based complete feed could be prepared in mash, block and pellet (Expander and extruder) form. In this system, all feed ingredients including roughages are proportioned, processed and mixed into a uniform blend. Different researchers undertook feeding trials of complete animal feed and conventional animal feed and reported better performance in terms of weight gain, milk yield and reproductive performance on feeding complete feed pellets or complete feed blocks to ruminants as compared to conventional ration. In conclusion, crop residue based complete feed could improve ruminant performance and reduces cost of feeding per kg gain or yield and thereby improving livestock based rural economy in developing countries like India.

The ethnobotanical study carried out on the fruits of chilli (Capsicum annuum L.), type "Ahalimancou" in the localities of Aniassué, Affalikro, Sankadiokro and the town of Abengourou located in the east of the Côte d’Ivoire had for main objective to assess the levels of knowledge, the mode of use of this pepper by the local populations, as well as the phytochemical analysis of said chilli. Discussion groups and semi-structured individual interviews were carried out in 4 localities to collect information from 650 inhabitants, including 511 women and 139 men. The results showed that the variables gender, age group, ethnicity and level of education significantly influence (p≤0.05) the levels of knowledge and the mode of use, except the independence between the locality, the level of knowledge and mode of use. In addition, women know more about this type of pepper (80.82%) and use it much more in food (99.41%), as well as in the treatment of diseases (95.69%). People aged 60 and over have higher use levels (81.30%) in therapeutic use. The study also revealed that the Agni ethnic group is distinguished from other ethnic groups (Baoulé, Malinké, Attié) by a greater level of knowledge and use in pathology. Depending on the level of education, it appears that people without education know better (71.63%) and use this type of pepper more in the treatment of pathologies (85.39%). In addition, the study showed that the fresh form remains the only form used. With the exception of quinones, phytochemical analysis revealed that this type of pepper contains several pharmacological components depending on the stages of ripeness. Orange and red fruits had a higher content of alkaloids, polyphenols, flavonoids. The green and yellow fruits were highly rich in sterols and polyterpenes. Catechetical tannins were only present in green fruits. The data from our study could strengthen clinical research on the nutritional and pharmacological properties of this type of “Ahalimancou” chilli.

An erythrocytosis describes an increased erythrocyte, subclassified into relative due to hemoconcentration or absolute by an increase in erythrocyte mass, defined as an increase in hemoglobin concentration and/or hematocrit in the peripheral blood above the sex-specific normal range. Budd-Chiari Syndrome (BCS) is related to an obstruction of the hepatic venous flow leading to occlusion of hepatic veins and their tributaries. Genetic and environmental factors can interact for risk determination of venous thromboembolism. The risk associated with SNP 677C>T and 1298A>C of the methylenetetrahydrofolate reductase (MTHFR), 1691G>A of the Factor V Leiden (FVL) and 20210G>A of the prothrombin (FII) genes were investigated in many studies involving thrombosis. This case report describes the clinical, hematological and biochemistry data about a 48-year-old woman diagnosed with PV and a BCS associated, also carrying 677C>T SNP in homozygosity. The patient started therapy with phlebotomy, hydroxyurea and oral anticoagulant. Currently, she presents a better clinical and laboratory condition with normalized values of hematological and platelet indices. This case report aims to contribute with evidence of related comorbidities and makes it possible to report that genetic factors are involved since the patient's mother had already been diagnosed with absolute erythrocytosis in 2016 at 78 years old. For this main result, we understand that it is clear that a family genetic study can reveal clinical modifying factors in these patients, as there are different clinical severities in the family. Furthermore, we believe in the need for a greater number of randomized clinical trials to add better evidence to complement an ideal therapeutic approach in these patients.

To study the impact of vermicompost, arbuscular mycorrhizae and FYM application on the rice ecosystem at low land, a field experiment was conducted with rice CO(R) 51 at the Department of Soil Science and Agricultural Chemistry, Tamil Nadu Agricultural University in Coimbatore during the winter of 2020. The experiment was framed in Randomized Block Design comprising of 8 treatments viz., Recommended Dose of Fertilizer Soil Test Crop Response approach (T1), RDF 75 % + Farm Yard Manure @ 12.5 t ha-1 (T2), T2 + Seed treatment with Azospirillum and Phosphobacteria + Soil application of AM fungi (T3), RDF 75 % + Vermicompost @ 5 t ha-1 (T4), T4 + Seed treatment with Azospirillum and Phosphobacteria + Soil application of AM fungi (T5), FYM @ 12.5 t ha-1 + Seed treatment with Azospirillum and Phosphobacteria + Soil application of AM fungi (T6), Vermicompost @ 5 t ha-1+ Seed treatment with Azospirillum and Phosphobacteria + Soil application of AM fungi (T7) and Absolute control (T8) and replicated thrice. The maximum microbial population were registered in the plots that received integrated nutrient application of RDF 75 % STCR approach + Vermicompost 5 t ha-1 + seed treatment with Azospirillum and Phosphobacteria + Soil application of AM fungi. Rice root architecture has changed significantly as a result of mycorrhizal inoculation. Mycorrhizal rice plants have more root volume, length, and spread than plants without mycorrhizae. Nutrient retention and availability influenced the presence of microbial-mediated metabolic activities and nutrient transformations during crop growth. Bacteria, fungus, and actinomycetes became less abundant as the crop reached harvest. The population density of mycorrhizospheres that utilize both organic and inorganic fertilizers is higher. The treatments that received Vermicompost or FYM with Vesicular Arbuscular Mycorrhizae and Nitrogen, Phosphorous & Potassium fertilizers obtained the highest yields of rice grain and straw (6740 and 7840 kg ha-1) respectively, and it was clear that the combination of Vermicompost or FYM, VAM and along with NPK fertilizers produced significantly higher yields than their individual applications and absolute control.
