Authors: Shukla U.K. , Thakur Rohit , Kant Shri
Published: March 2022

The experiment was conducted at the Livestock Production and management unit, Department of N.R.M Faculty of agriculture MGCGV Chitrakoot - Satna M.P. To complete the research work following steps were followed. Day old 75 broiler chicks (DOC) of same hatch were produced and reared in Deep Litter system. The chicks were weighed, leg banded and distributed randomly into five groups of 15 chicks each as treatment. Chicks of each treatment were further divided into three sub groups of five chicks in each in Randomized Block Design ( RBD). Chicks of each sub group were accommodated comfortably in Deep litter system providing 1sq. ft./ chick. Chicks were fed standard starter ration upto 2 weeks age (1 to14 days) and then broiler finisher ration upto 2 weeks (15-28 days). An experiment was conducted with DOC to 75 broilers chicks divided into five groups To T1, T2, T3 and T4 which were supplemented with Neem, Tulsi, Mentha powder @ 1.0g, 1.5g, 2.0g and 2.5g/kg of broiler ration, respectively. Weekly observations were recorded for live body weight, weekly gain in weight, weekly feed consumption and feed conversion of birds for four weeks. Based on the result of the experiment, it may be concluded that feed supplementation with Neem, Tulsi, and Mentha powder significantly influenced the body weight, gain in body weight, feed intake and feed efficiency of broiler chicks. Based on feed intake and feed efficiency, the best performance of broilers was obtained with feed followed by 2.5g Neem 2.5g Tulsi 2.5g Mentha powder (T4). Treatment T3 was economically superior over all other treatments and control.

The problem of recognition and classification of biomedical signals is a complex problem related to the interdisciplinary field of computer science and medicine. Within the framework of the project implementation of the development of the new defibrillation equipment, it is necessary to solve the problems of analyzing biomedical signals of the electrocardiogram to obtain a diagnostic solution with the possibility of assigning a specific condition to the pathological condition of the patient. This article presents the analysis of electrocardiogram signals, considering the technical aspects of the analysis of multicomponent signals, and describes the diagnostic possibility of wavelet analysis of ECG signals. The paper considers the limited tools of analyzing the electrocardiogram signal, in particular, limitation of parametric data. Wavelet analysis may significantly expand the analysis of signals and transfer them into the time-frequency domain. Thus, the use of various basic functions of the wavelet transform leads to the determination of the additional diagnostically significant information formalized in the parameters extracted from the wavelet scalogram.

Published: March 2022

ABSTRACT The salinity of irrigation water and soil create considerable challenges in agriculture, as they harm the physiological processes and growth of plants. The exogenous application of antioxidant compounds, such as salicylic acid, can reduce the damage caused by salt stress. Thus, this study aimed to evaluate the attenuation of salt stress induced by salicylic acid in Ocimum basilicum “Cinnamon”. The experiment was performed in randomized blocks with five irrigation water salinity levels (0.5, 1.3, 3.25, 5.2 and 6.0 dS m-1) and five salicylic acid concentrations (0, 0.29, 1.0, 1.71 and 2.0 mM), with five repetitions and two plants per plot. Growth, gas exchange, and chlorophyll indices and fluorescence were evaluated 30 days after the salt treatment was applied. An increase in the salinity of irrigation water decreased the plant height, stem diameter, number of leaves, stomatal conductance, instantaneous water use efficiency, and initial fluorescence of basil “Cinnamon”. Salicylic acid was revealed to attenuate the harmful effects of irrigation water salinity on gas exchange, total chlorophyll, and initial and maximum fluorescence of basil plants.

Published: March 2022

ABSTRACT Peanuts are one of the most produced legumes in the world; however, there is a lack of knowledge on their nutritional needs and the growth phases with greater demands; therefore research is required on the nutrient absorption rate of the crop. The objectives of this study were to determine the rates of absorption in the vegetative part and the pods, the accumulation of macronutrients in the vegetative part, pods, and in total, and the nutrient export to pods during the cycle of the peanut, cv Runner IAC 503, grown under full irrigation. The experiment was conducted at the Experimental Farm of the Faculty of Agrarian and Veterinary Sciences, Universidade Estadual Paulista, Jaboticabal campus, SP, Brazil, from March to August 2019 using a randomized block design, with evaluations of the macronutrient absorption rate and accumulation at 35, 49, 63, 77, 91, 105, 119, 133 and 147 days after sowing, with four replications. Higher nutritional demands of peanuts occurred between 63 and 105 days after sowing. Greater total accumulation of nutrients was reached at 118 DAS, with 234.8, 173.5, 79.0, 45.8, 23.4 and 18.8 kg ha-1 for N, K, Ca, Mg, P, and S, respectively. Exports of macronutrients contained in the pods totaled 138.8, 43.9, 14.6, 12.0, 7.3 and 5.4 kg ha-1 for N, K, P, Mg, S and Ca, respectively. Exported K in the harvest was two times greater than the applied amount at sowing, which followed the current Brazilian recommendation, causing possible depletion of this nutrient in the soil.

Authors: Plauto Monique Sá e Benevides de Carvalho , Cavalcanti Catarina Calábria Figueirêdo , Jordán Arturo de Pádua Walfrido , Barbosa Leopoldo Nelson Fernandes
Published: March 2022

Abstract: Introduction: In the medical field there are still gaps regarding the concept of death and the finitude of life, very often understood as a failure of Medicine and not as an integral part of existence. In this context, the view of death as an error, the failure of a treatment, generates anxiety and demands by doctors themselves, which can affect their physical, mental and spiritual health. Objective: To analyze the relationship between spirituality, religious practices, and quality of life of medical professionals in the field of oncology and palliative care who deal with the finitude of life on a daily basis in a reference hospital in northeastern Brazil. Method: Cross-sectional, analytical and quantitative study with an intentional and convenience sample. Questionnaires were applied to describe the sociodemographic profile, quality of life (WHOQOL - bref) and spirituality using the Brief Religious/Spiritual Coping Scale (Brief RCOPE) and the Spirituality Self Rating Scale (SSRS). Data analysis used the Statistical Package for the Social Sciences (SPSS), version 13.0 for Windows. The study was approved by the REC of IMIP under Opinion 2,890,118. Result: Twenty oncologists and palliative care physicians participated in the study; most were women (55%), of white ethnicity (60%), Catholic (80%) and married (70%). The SSRS scale identified an average score of 21.75. In the Brief RCOPE, the positive aspect scored 2.64, the negative aspect 1.47, and the total aspect 2.04. There was a significant positive association between the SSRS and RCOP results (p=0.0). When associating WHOQOL - bref with Brief RCOPE, a direct relationship with statistical significance of the psychological domain was obtained with total RCOP (p-value: 0.01) and with negative RCOP (p-value: 0.03). Conclusion: The study showed a relationship between spirituality and quality of life, as well as positive aspects of faith for coping with everyday stress, corroborating the discussion of the importance of including spirituality as a protective factor in health.

Abstract: Introduction: Since the National Curricular Guidelines for the Medicine course were implemented, with emphasis on the training of professionals with a generalist profile, the factors that may contribute to the interest in professional practice are unknown. Objective: This study aimed to analyze the perception of medical students regarding their generalist training and the factors that influence the desire for professional practice. Methodology: Descriptive and analytical cross-sectional study of qualitative and explanatory character with 523 students from different medical courses in the city of Salvador-Bahia, who answered an online survey after signing the informed consent form. The sample was categorized into interest in Immediate Specialization (IS) and among those who intend to Act as a Generalist (AG). The age and period of the course were also categorized into groups. Results: The age of the sample was 18 to 25 years in 83.7% (n = 438), with 72.5% (n = 380) being female, attending 69% of the 4º to 9º semesters (n = 363). The Immediate Specialization group represented 27.2% (95% CI: 35% -73%) and the group that intends to Act as a Generalist, 72.8% (95% CI: 68% -76%). General training did not influence the option for professional practice with RR = 0.81 (95% CI: 0.55-1.20) p = 0.308. The factors associated with AG were believing in the generalist’s resolution capacity and SUS guidelines (p <0.001), the desire to contribute to society (p = 0.005) and society’s credibility (p = 0.044). Conclusion: Students perceive that the curriculum includes general training, however it did not influence the interest in professional practice. The desire to act as a generalist is present in a significant number among them, driven by altruism and the desire to contribute to society, supported by the organic laws that underlie the SUS Guidelines, while not feeling valued and having its credibility, questioned by society, only stimulates professional practice on a temporary basis.
O processo de esportivização do remo na cidade de São Paulo (1899-1949)
Authors: Medeiros Daniele Cristina Carqueijeiro de
Published: March 2022

RESUMO O objetivo deste artigo é analisar a esportivização do remo na cidade de São Paulo. O período recortado é aquele em que o remo foi praticado prioritariamente no rio Tietê. Parte-se da hipótese de que os clubes de regatas e as federações foram elementos fundamentais na transformação do remo na cidade. A análise das fontes mostra que paulatinamente os torneios ganharam contornos mais competitivos e regulamentados. Em meio a estes processos, o rio Tietê, com suas particularidades geográficas, configurava-se como um grande impedimento à esportivização do remo. Conclui-se que ao mesmo tempo em que as práticas ganhavam características mais esportivizadas, semelhantes àquelas internacionalmente instituídas, elas esbarravam nas conjunturas locais, expressas pela geografia do rio Tietê.

Authors: Kungoane Tsholofelo , Robinson Liam M , Madiba Thomas K
Published: March 2022

Frozen section (FS) analysis is an indispensable tool for intraoperative patient management.To assess the utilisation of head and neck FS analysis, with a particular focus on the concordance rate between the intraoperative FS margin analysis and the final FFPE results. Additionally, to determine whether FS analysis had any impact on intraoperative patient management.Lastly, to determine the impact of the FS analysis on the final margin status of resection specimens. Histopathology reports from January 2015 to December 2018 were reviewed at Pretoria Oral and Dental Hospital to analyse all FS requests involving the head and neck region. Captured data was analysed to determine the concordance rate, discordance rate, and FS deferral rates, with correlations performed using the Chi-square test. Eighty-two frozen section cases were reviewed with a total of 312 FS tissue sections performed. The majority (73%) of the FS requests were from the Maxillofacial and Oral Surgery (MFOS) department for the assessment of surgical margins. The FS-FFPE concordance and discordance rates were at 97.5% and 2.4% respectively, with a deferral rate of 1.2%. Additional surgical margins were only received in 16 of the 26 cases with positive margins on intraoperative FS analysis. There was no statistically significant correlation between intraoperative FS positive margin status and advanced pathological T staging. The concordance rate between intraoperative FS margin analysis and final FFPE results were within an acceptable range. In a significant number of cases, the intraoperative FS margin analysis did not influence further surgical management.

Published: March 2022

Heart failure (HF) remains a serious problem in Russian and world health care due to the growing morbidity and mortality from complications of heart failure, despite the development and implementation of programs for the early detection and treatment of heart failure in asymptomatic patients. Currently, a large number of new biological markers have been studied that could serve as a laboratory tool for diagnosing and predicting the course of heart failure, but only brain natriuretic peptides have found application in real clinical practice. Renalase is a recently discovered cytokine that is synthesized by the kidneys and released into the blood. To date, seven subtypes of renalase have been found, each of which plays a different physiological role in the human body. Renalase is usually positioned as a signaling molecule that activates cytoprotective intracellular signals, leading to a decrease in blood pressure and protection of the heart muscle. The concentration of renalase freely circulating in the bloodstream of an adult is approximately 3–5 ng / ml. Currently, the level of renalase is determined by the enzyme immunoassay with a detection range of 3.12 to 200 ng / ml, while the minimum detectable concentration of the marker is less than 1.38 ng / ml. The presence of missense polymorphism of renalase is associated with myocardial dysfunction. Data from animal and human studies have shown that renalase plays a key role in the metabolism of catecholamines and in cardioprotective processes. Studies have shown the contribution of renalase to the occurrence of cardiovascular diseases: ischemic heart disease, arterial hypertension, diabetes mellitus, and aortic stenosis. Moreover, detailed protocols of multicenter prospective studies have demonstrated that functional polymorphism of the renalase gene was associated with myocardial hypertrophy in patients with aortic stenosis, hypertension, metabolic syndrome, unstable angina pectoris and stable forms of coronary artery disease, as well as in patients receiving renal replacement therapy. Based on these data and further studies, renalase has been proposed as a predictive biomarker of ischemia in patients with coronary microvascular dysfunction, as well as a predictor of clinically significant progression of chronic kidney disease in patients with cardiovascular diseases.

Our review presents data on the role of renalase in heart failure. Further study of the structure and function of renalase, as well as future clinical studies, will allow determining the diagnostic, prognostic and, possibly, therapeutic significance of this biological marker in HF and other cardiovascular diseases.
Fixation with zinc-formalin as an adequate substitution of Zenker-formol for the histochemical staining of the pancreatic islet cells
Authors: Manskikh Vasiliy Nikolaevich
Published: March 2022

AIM: The work aimed to determine the possibility of using zinc-formalin fixation instead of Zenker-formol to identify selectively all the main types of cells (A, B, D) of the pancreatic Langerhans islets by staining using classical histochemical methods.
MATERIALS AND METHODS: Pancreatic samples of the naked mole rat (Heterocephalus glaber, Rppell, 1842) were fixed for 24 hours in zinc-formalin fixative containing 300 ml of 37% formaldehyde, 50 g of zinc chloride, 1.9 ml of glacial acetic acid, and 2 L of distilled water. After fixation, the standard procedures for paraffin embedding and staining with Heidenhains azan and a combination of azan and Gomoris paraldehyde-fuchsin were performed according to routine protocols.
RESULTS: It was revealed that a distinctive differential staining of all three major types of islet cells can be obtained if pancreatic samples are fixed in a zinc-formalin fixative for 24 hours. At the same time, as after fixation with Zenker-formol (but not with formalin solution or Bouin fixative), not only A and B, but also D-cells are clearly identified. Comparison of the immunohistochemical data on the distribution pattern of various cells in the pancreatic islet in a naked mole rat with that detected by histochemical stains showed their complete coincidence.
CONCLUSIONS: Zinc-formalin can be used as a more convenient and safer fixative for detecting Langerhans islet cells (including D cells) by staining with Heidenhains azan and Gomoris paraldehyde-fuchsin instead of mercury salt-containing Zenker-formol.

Visual acuity and quality of life in heavy visual workload patients with bilateral cataract before and after phacoemulsification
Authors: Pokrovsky Dmitry F. , Ovechkin Nikolay I.
Published: March 2022

BACKGROUND: To date, there is a number of debatable aspects of cataract phacoemulsification in the literature, one of which is the investigation of features of the surgery in patients with visually stressful work.
AIM: The aim is to investigate the dynamics of the best corrected distance visual acuity and quality of life in heavy visual workload patients with bilateral cataract before and after phacoemulsification.
MATERIALS AND METHODS: We observed 32 heavy visual workload patients with binocular cataracts. All patients underwent standard phacoemulsification using Infiniti (Alcon, USA) or Constellation (Alcon, USA) devices according to the standard technique. The quality of life was assessed using the tested in refractive surgery QOL-25 questionnaire.
RESULTS: The high efficiency of phacoemulsification surgery was established, which is confirmed (14 days after the second procedure) by an increase in best corrected distance visual acuity to an average value of 0.920.95 relative units. Along with this, a certain quality of life dynamics of was revealed, which is manifested by a statistically significant deterioration (by 2.34.7%, p = 0.020.008) in the index in 14 and 21 days after the first surgical procedure compared to the data obtained at 7 days after first operation.
CONCLUSION: Surgical treatment of binocular cataracts in heavy visual workload patients is based on earlier (in 710 days) surgery on the second eye or performing an immediately sequential bilateral cataract surgery.

BACKGROUND: In recent years, autologous serum has been increasingly used in the treatment of macular hole. The study carried out a biological analysis of autologous serum obtained by various methods.
AIM: The aim of the investigation is to compare the cellular and biochemical composition of autologous serum obtained using different methods for use in the macular hole treatment.
MATERIALS AND METHODS: The study of the number of platelets, leukocytes and fibrinogen level in the blood serum of 24 patients obtained by centrifugation in original systems for harvesting autologous serum and laboratory test tubes was performed.
RESULTS: The indices of P-PRP obtained in the Arthrex ACP system and in a laboratory test tube do not statistically differ in quantitative indices of fibrinogen and platelets (p 0.05), and differ in the content of leukocytes (p 0.05) in the direction of increasing the number of leukocytes in the substrate obtained in a laboratory test tube. The indicators of L-PRP obtained in the Ycellbio-Kit system and in a laboratory test tube do not statistically differ in the amount of fibrinogen (p 0.05) and differ in the content of platelets and leukocytes (p 0.05) in the direction of decreasing the concentration of leukocytes and platelets in the autologous serum obtained in a laboratory test tube.
CONCLUSIONS: Currently, autologous serum obtained in the Arthrex ACP system is of great interest for macular hole surgery due to the minimal content of leukocytes, the closed character of the system, and the best coagulation properties of the substrate obtained. Laboratory test tubes may be considered a more affordable alternative for the production of autologous serum (P-PRP) for the treatment of macular hole. The autologous serum (L-PRP) obtained in the Ycellbio-Kit system and in a laboratory test tube is less suitable for macular hole surgery according to its composition.
The level of prevalence and risk factors of strabismus among children and adolescents, depending on the type of settlements in the Ganja-Gazakh economic district (Azerbaijan)
Authors: Abdiyeva Yazgyul
Published: March 2022

BACKGROUND: Strabismus as a pathological condition complicating the visual function and affecting the behavioral functions of children is often in the center of attention of numerous studies. The presence of regional differences in the strabismus prevalence makes this problem a relevant to study issue in the regions of Azerbaijan.

AIM: To assess the prevalence rate of strabismus among children depending on the settlement type.

MATERIALS AND METHODS: A prospective observation of a sample of children aged 519 years was carried out; the sample size was determined taking into account the size of the margin of sampling error less than 5%. 300 children at the age 59, 1014, 1519 years (150 boys and 150 girls) in a large town (Ganja) and rural settlements of Ganja-Gazakh region (2700 children in total) have been observed. In all children, an ophthalmologic examination was performed by specialists of the mobile team of the National Ophthalmological Center named after academician Z. Aliyeva.

RESULTS: Strabismus was found in children aged 5-19 years in 4.6 0.7% of cases in a large town and in 2.7 0.5% of cases in rural settlements. Significant differences of prevalence rate of strabismus by age and gender were not confirmed.

CONCLUSIONS: In the region, the incidence of strabismus among children aged 519 years was 3.8 0.4%. In a large town, the risk of strabismus among children is high. In children with strabismus, refractive errors and perinatal conditions (prematurity) are often found.
Wind turbine blades fault detection using system identification-based transmissibility analysis
Authors: Wang Xuefei , Zhang Long , Heath W P
Published: March 2022

Wind turbines (WTs) are extensively installed nowadays and the blades are integral components within the WT systems. Condition monitoring and fault diagnosis (CMFD) for WT blades is challenging due to the fact that they usually suffer from non-stationary time-varying loads and the load
information is often unknown or hard to collect. This paper proposes system identification-based transmissibility function (TF) methods to effectively detect the blade defects and further help to prevent potential economic loss. The novelty is that the proposed methods only use output response
information in the time domain, which can therefore remove the impact of the input excitation. Four different models are used in this work to estimate the blade structure system parameters, including the autoregressive with eXogenous input (ARX) model, the autoregressive moving average with
eXogenous input (ARMAX) model, the output error (OE) model and the non-linear ARX polynomial model. Regularisation is then employed to address the overfitting issues that may occur during parameter estimation. The effectiveness of the proposed methods are demonstrated in the laboratory using
three naturally damaged industrial-scale WT blades.

Government fragmentation and educational outcomes: evidence on the creation of municipalities in Chile
Authors: Alcaíno Manuel , Jaimovich Analia , Méndez Carolina , Vásquez Diana
Published: March 2022

We explore how government fragmentation affects public education provision by examining the case of Chile, which created 11 municipalities between 1994 and 2004. Using territories that sought, but failed to, achieve independence as controls, we find that schools in newly created municipalities, on average, experienced a standard deviation decline of 0.2 in elementary school mathematics performance. In addition, fragmentation led to a high turnover and increased job insecurity of classroom teachers and school management teams in newly created municipalities. In contrast, we found that reducing the size of the original municipalities school networks does not impact student outcomes or school personnel. Overall, our findings point to specific unintended educational effects of policies that seek to enhance horizontal decentralization.

Published: March 2022

Zdi se, da kljub nedorečeni deﬁniciji področja, o umetni inteligentnosti (UI) danes vsi vse vemo. V ožjem, raziskovalnem smislu, se UI povezuje tako z razvojem novih računskih metod kot njihovo uporabo v praksi. V prispevku poročamo o rezultatih analize bibliografskih zapisov s področja UI od leta 2000 do danes. Predstavimo konstrukcijo omrežja sopojavnosti ključnih besed v času in analiziramo tematike, s katerimi so se ukvarjali raziskovalci v preteklih dveh desetletjih.

Authors: Jug Julijan , Lampe Ajda , Peer Peter , Štruc Vitomir
Published: March 2022

Segmentacija je pomemben del številnih problemov računalniškega vida, ki vključujejo človeške podobe, in je ena ključnih komponent, ki vpliva na uspešnost vseh nadaljnjih nalog. Več predhodnih del je ta problem obravnavalo z uporabo večciljnega modela, ki izkorišča korelacije med različnimi nalogami za izboljšanje uspešnosti segmentacije. Na podlagi uspešnosti takšnih rešitev v tem prispevku predstavljamo nov večciljni model za segmentacijo/razčlenjevanje ljudi, ki vključuje tri naloge, tj. (i) napoved skeletnih točk, (ii) napoved globinske predstavitve poze in (iii ) segmentacijo človeškega telesa. Glavna ideja predlaganega modela Segmentacija-Skelet-Globinska predstavitev (ali na kratko iz angleščine SPD) je naučiti se boljšega modela segmentacije z izmenjavo znanja med različnimi, a med seboj povezanimi nalogami. SPD temelji na skupni hrbtenici globoke nevronske mreže, ki se razcepi na tri glave modela, specifične za nalogo, in se uči z uporabo cilja optimizacije za več nalog. Učinkovitost modela je analizirana s strogimi eksperimenti na nizih podatkov LIP in ATR ter v primerjavi z nedavnim (najsodobnejšim) večciljnim modelom segmentacije telesa. Predstavljene so tudi študije ablacije. Naši eksperimentalni rezultati kažejo, da je predlagani večciljni (segmentacijski) model zelo konkurenčen in da uvedba dodatnih nalog prispeva k večji skupni uspešnosti segmentacije.
