Published: September 2022

Shear wave velocity is one of the essential parameters for describing hydrocarbon reservoirs that have several applications in petrophysical, geophysical, and geomechanical studies. Shear wave velocity usually does not exist in all wells, especially in old oil fields. In the current study, two equations of Carroll and Castagna have been modified, and linear and nonlinear multi-regressions were used to estimate shear wave velocity in an oil reservoir in southwestern Iran. Initially, compressional wave velocity and porosity were determined as the most effective wire-line logs on shear wave velocity by comparing their correlations. Then, two equations of Carroll and Castagna were modified. In addition, new equations based on porosity and compressional wave velocity for estimating the shear wave velocity were obtained. Shear wave velocity was estimated by new exponential equations in the wells of the current oil field with excellent goodness of fit by determination coefficients of 0.80 in the whole well, 0.72 in the Ghar-Shale-1, and 0.78 in Ghar-Shale-3 in X-07 well.

Published: September 2022

The removal of rock masses or their use with surface exploitation requires that this work be done at the lowest possible cost. The reduction of operating costs is done by analyzing each work action, working method, and the possibility of changing them, to have an impact on reducing costs. The drilling angle is one of the most important factors during surface exploitation by blasting. By changing the drilling angle, we achieve a reduction of the total drilling length, to have a reduction of the amount of explosives and other changes during the blasting process which do not greatly affect the cost of blasting. Determining the impact of drilling angle on the cost of blasting is determined by analytical methods and by comparing the results of applied drilling angle methods. During the analytical analysis of the blasting data and the comparison of their results, which was performed to determine the change in the cost of blasting depending on the drilling angle, and it concluded that for the removal of 200000 (m3) rock material, 356167.98 (€) can be saved, by applying the 90° angle drilling method. This change of drilling angle from the projected angle of 63° to the angle of drilling 90°, reduces the total cost of blastings by about 10.69 (%).

Analysis, assessment and comparison of climatic conditions of the stopes in the upper and lower horizons of the Trepça Mine in Stantërg, is as a basic principle to control as well as to improve them by providing a sufficient amount of fresh air to the main workplaces of the mine. The issue of the microclimate in various underground mining stopes shall require continuous measurements in the main places - stations, so for the overlying floors the previous measurements of the ventilation service were used for some stopes of deep horizons, and the measurements for certain time periods for 2021 have been forwarded. Measurements performed in different stopes of different horizons, creation of a database according to the obtained values and diagrams obtained for two microclimatic parameters (temperature and air humidity) as well as their analysis in scientific aspect offer us the best possible assessment which is argued in this paper. The presented results show that to improve the climatic conditions in the Trepça Mine in Stantërg, it is not only enough to change the ventilation system but also to direct (direction or regulation) a sufficient amount of fresh air in the direction of the analyzed stopes and those planned. This is done in order to provide better air conditions and to create a safe environment for the health of workers in underground work environments as a primary goal to increase high productivity of production.

Published: September 2022

This study uses linear programming to develop a methodology for selecting the best raw material mix in an ASCOM cement plant in Egypt. In cement factories, this type adheres to Egyptian chemical composition criteria for raw feed (e.g. 82.5% calcium carbonate, 14.08% silica, 2.5% alumina and 0.92% iron oxide). Furthermore, the model is bound by industry-specific characteristics (e.g. lime saturation factor, silica modulus, alumina modulus and loss of ignition). The results reveal that the model is able to accurately reproduce the mixing of high-quality feed with varying constituent percentages. It is also capable of determining the combining limitations of each ingredient. Furthermore, it demonstrates optimality for additive sourcing short-term planning and capping limestone quality to meet changeable component combinations. Additionally, improving the raw mix reduces limestone feed quality from 51 to 50.6%, resulting in the inclusion of extra limestone reserves.

The resurgence of the disease in humans that is very similar to smallpox called monkeypox (MPX) disease, caused by the monkeypox virus (MPXV), is the dominant topic of discussion in the scientific and popular press around the world right now. This is taking place as the world celebrates the historic accomplishments made in the fight against the Coronavirus Disease (COVID-19) pandemic MPX is currently thought to pose a risk to the general public's health, particularly in areas with high rates of MPXV infection and close human-wild animal contact. Despite the rarity of MPX outbreaks, they are often caused by human-to-human transmission, especially in households and healthcare settings. Recent decades have seen recurrent outbreaks of the MPX after the smallpox disease was declared eliminated and the consequent cessation of smallpox vaccination programs. MPX has presently spread to several countries throughout the world and posed a global public health emergency, with nearly 45000 confirmed cases in 96 countries and locations, and 12 deaths as of August 24, 2022. Even though this viral illness is thought to be self-limiting, its consequences and feasible pandemic potential seriously jeopardize public health. The main approach to avoiding MPX is to adopt appropriate prevention and control measures, increase awareness of risk factors, and inform the public of the steps they may take to reduce viral exposure. Scientific studies are currently looking at the viability and suitability of the MPX vaccination. This article presents a general introduction to MPXV / MPX along with progress in diagnosis, treatment, vaccination, and prevention and control strategies for tackling this global health emergency.

The severe acute respiratory syndrome coronavirus 2 (SARS – CoV2), the causative viral pathogen of the COVID-19 pandemic belongs to the family of Coronaviruses which are positive single stranded RNA viruses. The scientific fraternity has developed and developing various types of vaccines for prevention against COVID-19, such as inactivated virus vaccines, mRNA vaccines, replicating vector protein subunit vaccines, etc., Out of which ten vaccines namely Novovax, Covovax (protein subunit vaccines), Pfizer BNT16b2, Moderna mRNA 1273 (mRNA vaccines), Johnson & Johnson Ad26, Cov2.S, Astrazeneca AZD1222, Covishield (non-replicating viral vector vaccines), Covaxin, Sinopharm BBIBP-CorV, CoronoVac (inactivated vaccines) have been approved for clinical use by WHO. There is an urgent need for SARS-CoV2 specific therapeutics for the treatment of COVID-19 as there is the emergence of various variants such as Alpha, Beta, Gamma, Delta, Omicron, etc. The emergence of variants that possesses immune evading property and spike protein mutation have increased infectivity and more pathogenicity which impelled the need to develop various therapeutics for the treatment of COVID-19. This review compiles the information about potential antiviral candidates in preclinical trials intended for the treatment of COVID-19. The clinical development of such antivirals will be very crucial for the treatment of COVID-19 and also to curb the spread as the present scenario depends on the development of effective prophylactic vaccines.
Microbial biodegradation of nitrophenols and their derivatives: A Review
Authors: Alam Sk Aftabul , Saha Pradipta
Published: September 2022

Today, nitrophenols (NPs) represent chemicals highly in demand not only due to their function in synthetic chemistry but also due to their huge applications in several industries. Such diverse requirements and applications has resulted in a widespread abundance of these chemicals. Improper application and waste disposal practice results in the continuous discharge of these compounds into the environment and causes pollution threat to soil, groundwater, river water, etc. These xenobiotic chemicals are hazardous, toxic, carcinogenic, and mutagenic which results in serious health problems. The Nitro group present in the phenol makes them recalcitrant which causes the persistence of these chemicals in the environment. Although several chemicals, electrochemical, physical, and physicochemical methods have been proposed, bioremediation approaches mainly involving bacteria are considered best. To date, very few successful attempts (related to microbe-assisted bioremediation) have been carried out with environmental habitats for the removal of NPs (both in-situ and ex-situ attempts). So, as far as the effectiveness of the bioremediation process for NP decontamination is concerned, we are far away. More explorative studies using efficient aerobic-anaerobic NP degrading bacterial consortium (or combination of microbes- plant systems) and advanced techniques including omics approaches and nanotechnologies may help towards developing better practicable bioremediation approaches, in the future. This review article focuses on the list of nitrophenol degrading microorganisms, biodegradation pathways of NPs, bioremediation by immobilized cell technique, and the advantages and disadvantages of bioremediation. This article will increase our knowledge of the biodegradation of NPs.

Published: September 2022

Peanut (Arachis hypogaea L.) is vulnerable to many diseases. Vietnam and other regions where peanut is widely cultivated have a high threat of fungal and other plant diseases. Various fungicides are available to control the fungal disease but these have various harmful effects on the natural flora, fauna, and environment. Transgenic peanut lines which possess antifungal activity provide a possible solution in managing fungal diseases apart from the traditional resistance and fungicide usage. Therefore, this study evaluated the probable growth and development of chitinase transgenic peanut lines against Sclerotium rolfsii, a pathogen that causes “southern blight” in plants, under greenhouse conditions. This study provided evidence that through Agrobacterium itumefaciens mediated transformation, 42 kDa chitinase genes from Trichoderma asperellum, which is under the regulation of 35S promoter, were successfully incorporated into the peanut’s (A. hypogaea L.) genome and expressed in their plants. This evidence also demonstrated that transgenic peanut lines were suitable for growing and developing in the greenhouse. Further, it was reported that transgenic peanut lines took approximately 133 to 145 days from planting to maturity. These results also revealed that various growth characteristics of transgenic peanut lines having two synthetic genes (syncod Chi42-2 i.e. S2-2, S2-4, S2-6, and syncod Chi42-1 i.e. S1-1, S1-2, S1-3) were greater than that from the wild-type Chi42 (WT-1, WT-2, and WT-3). In addition, yield-related parameters including the number of mature pods, 100 pods weight and 100 seeds weight for all the transgenic peanut lines were higher than that of the non-transformed plant. Among the transgenic lines, line S2-4 exhibited significantly higher growth and yield than the other transgenic lines. These results demonstrated that 42 kDa chitinase genes overexpressing peanut lines could be a candidate for improvement against plants to phytopathogenic fungus S. rolfsii and high yield.

Published: September 2022

The study assessed the willingness of smallholder farmers to adopt the recommended agronomic practices of Bambara groundnut in semi-arid lands of Embu County. The study was carried out in three sub-counties i.e. Mbeere North, Mbeere South, and Embu West, of Embu County. Data were extracted with the help of a well-structured questionnaire which was distributed to 384 smallholder farmers who were participants at the farmers’ field schools at the three sites. The data were analyzed using means, percentages, and logistic regression. Results of the study revealed that 60.94% of the farmers were willing to adopt the recommended agronomic practices. The willingness of the farmers to adopt the recommended agronomic practices was influenced by farming experience, farm size, extension contact, participation in farmers’ groups, cropping technologies adoption, and intercropping system used by the farmers. The application of the farmer participatory approach is an innovative way of introducing and promoting less popular but sustainably proven agricultural technologies among smallholder farmers. This is a climate-smart strategy to address the challenges of food in the area. Awareness creation among the farmers using the right extension channels can increase farmers’ willingness to adopt climate-smart technologies such as the production of the highly nutritive and drought tolerant Bambara groundnut in dry areas.

Published: September 2022

Dizziness and vertigo are common among the adult and elderly population. However, the knowledge & awareness of vertigo and the understanding of the differences between vertigo and dizziness in the adult population is seldom studied. The present study aimed to assess the level of awareness and knowledge of vertigo among the adult population living in Selangor, Malaysia. In addition, the study also focused on the participants’ knowledge of differentiating dizziness and vertigo. This cross-sectional study received responses from 189 participants who were in the age range between 20 and 40 years among which 152 participants' responses met the inclusion criteria. A self-developed validated online questionnaire was used as a study tool to understand the awareness and knowledge of vertigo among the participants. Data analysis was conducted using SPSS (version 28) to obtain frequency and percentages. The results of the present study showed that 57.9% of participants had an average level of awareness of vertigo. Further, 55.3% disagreed that vertigo is the same as dizziness however only 6.6% of the participants were exactly able to identify the differences between vertigo and dizziness. The present study concludes an average level of awareness and knowledge of vertigo among most young adults of Selangor, Malaysia. However, the ability to differentiate vertigo from dizziness was very low among the participants, demonstrating a gap in their knowledge of vertigo. Hence, education about vertigo among the public must be ameliorated. Further studies are required on different age groups and within the other states of Malaysia.

Published: September 2022

Breast cancer has been attributed to be the second most common malignancy in females worldwide after skin cancer associated with a significantly high mortality rate. Tumor suppressor genes have an indispensable role in maintaining genomic integrity as well as cell cycle regulation. Phosphatase and tensin homolog deleted on chromosome ten (PTEN) is one of the most frequently mutated human tumor suppressor genes, implicated in cell growth, survival, and suppressing tumor formation. As the tumor progresses to more advanced stages, genetic alterations tend to increase one such alteration is the mutation of the PTEN gene which is linked to programmed cell death and maintenance of cell cycle regulation. There is a syndrome known as Cowden syndrome associated with a high risk of breast cancer which is a result of an outcome of germline mutations in the PTEN gene. Loss of PTEN activity, either at the protein or genomic level, has been related to many primary and metastatic malignancies including breast cancer. This study focuses on developing a potential bioavailable ligand inhibitory molecule for PTEN, using a computer-aided drug design approach (CADD). A library of developed ligands consisting of 50 potential molecules was screened to find a potential candidate to be used for second generation drug development. Among them, LIG28 was adjudged as the most effective and potential PTEN inhibitor given its maximum binding affinity of ΔG -5.96Kcal/mole with a lower RMSD value. Carmer’s Rule of toxicity further revealed the compatibility and non-toxicity of the molecule. These observations underscore the importance of PTEN as a target in the development of tumorigenesis and the prognosis of breast cancer.

Published: September 2022

Knowledge of the feeding habit and the digestive physiology of a fish is important in making appropriate strategies for feed development and successful culture. Nutrient-rich small indigenous fish species (SIFs) are abundant in Assam, India. Puntius sophore, Mystus tengara, and Trichogaster fasciata of Gossaigaon, Assam are important SIFs for the local rural population, and also potential candidates for ornamental fish culture. The present study aims to evaluate the feeding habit and digestive enzyme activities of these species. Data obtained from the relative gut length and gut content analysis suggested that M. tengara is a carnivorous fish and the rest two fishes are omnivorous in habit. Further, the relative gut length was highest in T.  fasciata (4.20±0.45) and lowest in M. tengara (0.55±0.11). Digestive enzyme activity indicates a correlation with the dietary habit of the fish. Further, total protease, trypsin, and amylase activity was reported highest in P. sophore. Acid protease pepsin was found to be significantly higher in M. tengara complementing its carnivorous habit and gut anatomy. The present study has established some important information on the digestive enzyme characteristics and feeding habits of the three fish species. This information might be useful in the development of suitable feed for the fish species for their culture.

Published: September 2022

Transversal cross-section pores of lotus-type porous materials are generally considered circular; however, they exhibit various pore geometries, which affect their effective properties. The main objective of this work is to develop a generalized model which allows estimating the effective Young’s modulus of multi-void shape porous microstructures by exploiting a relationship developed to evaluate the effective Young’s modulus of porous materials with single-void shape. A procedure based on free software is then proposed to allow the application of the proposed generalized model on real lotus-type porous material images to estimate the effective Young’s modulus. The free tool allows the processing of real porous materials images to obtain multi-void shape microstructures and their pores parameters data. The validation of the generalized model has been established by confronting the obtained results with experimental data taken from literature; an excellent agreement was observed. Therefore, it can be concluded that the proposed procedure associated with the generalized model can be used efficiently for predicting the effective Young’s modulus of the multi-void porous materials, particularly lotus-type porous materials.

Apparently, the ‘overwhelming’ and abrupt changes and transformation that is on-going in teaching and learning at the higher education institutions (HEIs) due to Covid-19. Some learners are coping well, whilst majority are grappling with the teaching and learning challenges as presented by the Covid-19. Other learners (not would not) but cannot cope with the pressure and abrupt changes that take place in HE which result in dropping out of these learners. This article poses the question of whether we have exhausted strategies to curtail the dropping out of learners due to teaching and learning challenges. The article intends to spur discussion on how we can effectively assist the higher education (HE) learners who are struggling or failing to cope with the Covid-19 teaching and learning challenges. The focus is on the challenges caused using technology for teaching and learning. Thus, the sudden imposition of e-learning on curriculum contents designed for face-to-face contact learning due to covind-19 has exposed how unprepared developing nations are towards embracing the predictable future of education. There are indications that the postcovid-19 teaching and learning environment will possibly maintain the current e-learning practices. Have we our priority right in supporting the struggling learners.

Głównym celem prowadzonych analiz było sprawdzenie, czy dostępne na rynku certyfikowane urządzenia gazowe użytku domowego i komercyjnego (urządzenia wykorzystywane w zakładach gastronomicznych) można zasilać częściowo oczyszczonym biogazem rolniczym lub mieszaniną takiego biogazu z gazem ziemnym wysokometanowym grupy E lub gazem z regazyfikacji LNG. Aby odpowiedzieć na to pytanie, rozważono sytuację, w której biogaz rolniczy zostanie wstępnie oczyszczony z najbardziej niepożądanych zanieczyszczeń i docelowo będzie gazem składającym się z metanu (CH4), dwutlenku węgla (CO2) i tlenu (O2). Rozpatrywano cztery różne składy biogazu rolniczego, w których zawartość CH4 zmieniała się od 70% do 85%, natomiast CO2 – od 14,8% do 29,8%. Obliczone parametry energetyczne, a w zasadzie liczbę Wobbego tych biogazów, porównywano następnie z wartościami nominalnej liczby Wobbego gazów ziemnych grup Ln, Ls i Lw, podanymi w polskich przepisach prawnych. Innym rozpatrywanym wariantem było mieszanie częściowo oczyszczonego biogazu rolniczego z gazem ziemnym wysokometanowym grupy E lub gazem z regazyfikacji LNG w takich proporcjach, aby powstałe mieszaniny osiągnęły minimalne wymagania energetyczne dla gazów ziemnych grup Ls, Lw i E oraz minimalne i maksymalne wymagania energetyczne dla gazu ziemnego grupy S (gaz zawierający w swoim składzie CO2 rozprowadzany na Węgrzech). Określono proporcje mieszania tych gazów, podano potencjalne składy powstałych mieszanin, ich parametry energetyczne oraz ciśnienia zasilania urządzeń końcowych spalających te mieszaniny. Na podstawie przeprowadzonych obliczeń podano, które kategorie urządzeń można potencjalnie wykorzystać do zasilania ich bądź to częściowo oczyszczonym biogazem, bądź też jego mieszaninami z gazem ziemnym wysokometanowym grupy E lub gazem z regazyfikacji LNG. Opisano również, jakie ewentualne zmiany będą konieczne w takich urządzeniach, aby można je było bezpiecznie użytkować po zmianie gazu.

Technika spektrometrii w podczerwieni (IR) stosowana jest do identyfikacji substancji organicznych, polimerowych i w niektórych przypadkach materiałów nieorganicznych. Zgodnie z tezą, że era paliw kopalnych powoli zbliża się do końca, zaistniała konieczność szukania i testowania alternatywnych źródeł energii. Gaz ziemny zawierający metan stanowi źródło energii wytwarzające duże ilości gazów cieplarnianych. Magazynowanie i wytwarzanie energii z paliw takich jak biogaz stanowi jedno z wielu innowacyjnych podejść podczas produkcji w zamkniętych, neutralnych pod względem CO2 obiegach (biogazownie). Technologie służące do wytwarzania biogazu i wykorzystujące biogaz kwalifikują się do otrzymania dofinansowania wspierającego rozwój OZE. Biogaz jest uważany za odnawialne źródło energii, obieg węgla w cyklu produkcji jego surowców i zużycia jest zamknięty i nie wiąże się z emisją netto dwutlenku węgla. Spektrometry IR pracujące zarówno w zakresie średniej, jak i bliskiej podczerwieni dają możliwości analizy chemicznej i materiałowej z dużą czułością i dokładnością, przez co mogą być szeroko stosowane w monitorowaniu środowiska lub do kontrolowania prowadzonych procesów technologicznych. W artykule opisano analizę próbek biogazu za pomocą spektrometrii w podczerwieni z transformacją Fouriera z zastosowaniem kuwety gazowej o regulowanej drodze optycznej. Badane próbki pochodzą z przerobu odpadów gorzelnianych. Przedstawiono analizę próbek gazów wzorcowych będących głównymi składnikami biogazu oraz dokonano porównania otrzymanych widm IR z widmami rzeczywistych próbek biogazu. Podjęto próbę określenia możliwości użycia tej techniki do wykrywania zanieczyszczeń, takich jak obecność gazowego amoniaku. Przeprowadzone badania potwierdziły możliwości analityczne badania głównych składników biogazu. Zawartość substancji będących zanieczyszczeniami biogazu może okazać się za niska do ich oznaczenia w przypadku ich śladowych ilości, wtedy spektrometria IR może okazać się niewystarczająca m.in. do oceny skuteczności prowadzonych procesów oczyszczania biogazu, dlatego należy ją stosować w połączeniu z analizą GC.

Modern life, especially in large cities, exposes people to a high level of noise, high density of population, disrupted sleeping, large amount of excessive and controversial information as well as to other negative factors; all this may cause chronic psycho-emotional stress. The latest publications often use the term “Syndrome of megalopolis”, which means disruption of sleeping, high anxiety, and altered reproductive function. Medical treatment of infertility may also be considered as a stress factor, especially when infertility lasts for years and is aggravated with emotional frustration. Long-lasting distress may worsen health in general and suppress reproductive function, in particular. The review presents the data on the effects of maternal stress on folliculogenesis, especially when assisted reproductive technologies (ARTs) are used. Clinical data are presented alongside data from laboratory animal experiments. Different maternal stress models are taken into account in respect of their inf luence on oocyte maturation and embryo development. The interfering of psycho-emotional stress and reproductive function is the focus of the review. In these situations, exogenous hormones compensate for the stress-related disruption of the hypothalamic-pituitary-gonadal axis. When ARTs are implemented, stress-induced disruption of oogenesis is realized not via a decrease in hypothalamic and pituitary hormones, but by other ways, which involve paracrine mechanisms described in this review. Based on the literature analysis, one may conclude that stress negatively affects oocyte maturation in the ovary and suppresses subsequent embryo development. The role of some ovarian paracrine factors, such as BDNF, GDF-9, HB-EGF, TNF-α, and some others has been elucidated.

"Tańcząc w ciemnościach" Larsa von Triera – antymusical psychoterapeutyczny
Authors: Szuchiewicz Katarzyna
Published: September 2022

In his movie “Dancer in the Dark” Lars von Trier placed a reference to classical musicals. However, he did it to stress trenchantly the distinctiveness of his work. Characteristic elements of this genre including dancing and singing do not change the reality into an idyllic world but bare the tragedy of the situation of the main character. Musical scenes that are Selma’s images might be considered as a director’s play with a convention. Lars von Trier put intentionally into his movie peculiar shots to break the rules of the genre and to complete the plot. In this way he created a very original quality. Although the final scene brings no happy ending, it moves deeply the audience and nobody can be indifferent to the emotions it gives. This article tries to find the reason for which the director decided to make that peculiar movie.

In the thesis “Szpil, du fidl, szpil. Yiddish music films in the Polish interwar cinema” I have tried to characterize the phenomenon Yiddish music film. Analyzing two titles “Yidl with a Fiddle” (“Jidł mit’n fidł”, 1936, dir J. Nowina-Przybylski, J.Green) and “Little Mother” (“Mamełe”, 1938, dir J. Green, K. Tom) I have focused on the major characteristics of this species. Apart from music scenes there are also important inspirations by Jewish culture, tradition and language. It is to be stressed that these movies are popular not only in our country but also in United States.
Gatunkowe obrzeża nowej fali. Filmowy musical w Czechosłowacji lat sześćdziesiątych XX wieku
Authors: Góralik Mikołaj
Published: September 2022

The following article introduces the context of the development of a new movie genre in Czechoslovakia in the mid-sixties – namely musical. It also investigates the reasons of its popularity at that time. The traditions of Czechoslovakian movie song and the beginning of the music star system at that country are of particular interest too. The latter led to the strict cooperation between filmmakers and musicians. The breakthrough happened in year 1964 when four films of that kind were shown in cinemas: “Do You Keep a Lion at Home?”, “Lemonade Joe”, “If a Thousand Clarinets and The Hop Pickers”. At the same time first films of Czechoslovakian New Wave appeared and in the present film studies this phenomenon overshadowed musicals and other film genres of that era.
Rhizoctonia Aerial Blight of Soybean, its Prevalence and Epidemiology: A Review
Authors: Bhamra Gurpreet Kaur , Borah Munmi , Borah Pradip Kumar
Published: September 2022

Soybean [Glycine max (L.) Merrill] is high value oilseed crop grown throughout the world as well as in few soybean growing pockets in India. The hot and humid weather conditions during the soybean cropping season favours the attack by various fungal, bacterial and viral diseases, thereby lowering the crop productivity. Rhizoctonia aerial blight or web blight disease, caused by Rhizoctonia solani is considered one of the most economically important disease of soybean in India. It causes yields losses ranging from 35-60% which might reach a devastating level of 80% under favourable environmental conditions. In India, the disease has been reported from most of the soybean growing states of Uttrakhand, Rajasthan, Sikkim, Haryana, Punjab, Uttar Pradesh, Bihar, Madhya Pradesh, Chhattisgarh and Assam. Epidemiological studies prove to be very important in managing the disease as the disease severity highly depends on the weather variables prevailing in the growing season. The present review has attempted to compile findings on this devastating disease of soybean crops, its prevalence in the country, epidemiological studies and strategies on integrated disease management.
