Authors: Kasimovna Djabbarova Yulduz , Sh D Babazhanova , AS Lyubchich
Published: January 2021

In recent years, in practical obstetrics, placental adherence into the myometrium, diagnosed after the birth of the fetus during caesarean section or in the 3rd period of labor, has become increasingly common. It causes massive bleeding, hysterectomy and maternal mortality. Purpose: To assess the outcome of childbirth with organ-preserving technology in cases of placenta accreta. Material and methods: 56 women in placenta accreta were observed and delivered for 2016-2018. 49 women delivered by Cesarean section and 7 women gave vaginal delivery. Two methods were used to preserve the uterus during placenta accreta: the first method -35 women who have laparotomy, a cesarean section with a section on the uterus above the scar and above the edge of the placenta, ligation of the uterine arteries, excision of the incremental area and metroplasty, imposition of compression sutures on the uterus. The second method -7 women after vaginal delivery left the whole or part of the placenta in the uterus - placenta in situ. The risk of placenta accreta was placenta previa, scar on the uterus, abortions in anamnesis, over 30 years of age third or more births. Results and discussion: From 35 pregnant women who underwent an organ-preserving procedure for caesarean section, 33 (94,3%) women managed to preserve the uterus, the remaining 2 (5,7%) women underwent hysterectomy Of 7 cases of placenta in situ, in 2 (28,6%) cases a hysterectomy was performed и. and uterus was preserved in 5 (71.4%) women. Conclusions: The effectiveness of improved organ-preserving technology to preserve the reproductive function of women with placenta accreta is high. In the group with the organ-preserving method with placenta, the volume of blood loss, the volume of transfusion of blood components is much lower than in the hysterectomy group.

Authors: Putra Romy Ade , Susiarno Hadi , Harsono Ali Budi , Kusumadjati Adji
Published: January 2021

Background: Cervical carcinoma is the main malignant disease that causes death in women. Radiation is a therapy for cervical carcinoma. Radiation will induce apoptosis in carcinoma cells. Survivin as anti apoptosis will inhibit cervical carcinoma response to radiotherapy. For this reason, it is necessary to conduct a study that compares survivin levels in cervical carcinoma patients before radiotherapy with clinical response. Method: This study is an observational design with analytical cohort studies. The survivin serum level and mass size of 30 stage IIB cervical carcinoma patients were measured before radiotherapy, then the size of the mass was measured again after the patient completing radiotherapy. Mass size before and after radiotherapy is compared to determine the patient's clinical response to radiotherapy.The study was conducted at the Gynecology Oncology Clinic, Radiotherapy Department and Clinical Pathology Laboratory of Hasan Sadikin Hospital in January to July 2019. Result: Subjects with lower mean of survivin level, 111,789±2.47pg/mL produced a complete clinical response. Whereas subjects with a higher survivin level , 502,689±1.26pg/mL produced a partial clinical response. From the result of the T Test it was found that the mean of survivin serum levels were significant with p value of 0.029. Conclusion: The higher the survivin level before radiotherapy, the worse the clinical response to radiotherapy in patients with stage IIB cervical carcinoma.

Among the disorder sexual development which regroups several pathological entities, true hermaphroditism or Ovotestis disorder remains a rare variety. We report a case of true hermaphroditism, diagnosed at the age of 15 years. Despite the presence of sexual ambiguity at birth, the female gender has been declared. The presence of a female genital tract and secondary sexual characteristics has led the choice of scrotal excision. The surgical procedure, the histological study bestow the positive diagnosis and allowed to revise the sexual ambiguity.

Published: January 2021

Purpose – to investigate the problems of implementing a strategic planning system in industrial enterprises. 
Design/Method/Research approach. A theoretical approach based on the generalization of available research, analysis, and comparison to identify obstacles to the strategic planning implementation in industrial enterprises
Findings. It is substantiated that the strategy development and strategic planning system implementation are necessary conditions for a modern industrial enterprise's functioning due to the dynamism and instability of the economic environment. One of the most important factors influencing the economic entity's efficiency is the awareness of the need to implement a strategic planning system because it allows the company to achieve dynamic development and strengthen its market position. It is argued that among the problems that affect the strategic planning implementation in industrial enterprises, external factors of influence, internal factors of the organization, and factors related to the enterprise owner's motives.
Theoretical implications. The research's theoretical significance is to change the research focus in strategic planning from external factors to the enterprise owner's motives research. 
Practical implications. Owners and top managers can use the research to prevent problems with the enterprise's strategic planning implementation.
Originality/Value. The paper's originality is because, for the first time, the relationship between the dynamics and problems of strategic planning system implementation in industrial enterprises is considered by the personal motives of the enterprises' owners.
Research limitations/Future research. Further research forecasts further analyze the relationship between external and internal factors influencing strategic planning system implementation problems in industrial enterprises.
Paper type – theoretical.
Role of The Halal Industry in Recovering the National Economy in Covid-19 Pandemic
Authors: Susilawati Cucu
Published: January 2021

The outbreak of the Covid-19 pandemic in Indonesia is attacking not only public health but also the economy. The presence of Covid-19 has many important impacts on developed countries. There are at least four industries most impacted by this pandemic, including households, MSMEs, companies and the financial industry. However, the halal industry is believed to be more resilient to the Covid-19 pandemic. This durability is because of the principles attributed to the halal sector, namely the importance of fairness, balance and openness. The author’s goal is therefore to carry out more in-depth research on the role of the halal industry in supporting the national economy, which is under pressure because of the COVID-19 pandemic. This type of study is a literature review with a material analysis approach that explores the conditions of the halal industry in Indonesia in depth. The material received is as books, published information, and online news. The findings of this study reveal that there are three halal business sectors that are believed to be more vulnerable to the Covid-19 pandemic in order to facilitate national economic recovery. Halal finance, halal food and halal fashion industries are among them. Halal finance from both the banking sector and the Islamic stock market has proved to be more robust than the mainstream financial sector. Besides guaranteed halal food, its wellbeing is also guaranteed, and halal fashion is now on the rise as Muslim fashion is increasingly innovative and global. We believe the three of them to have experienced vigorous growth, and also to continue to draw customers. And also after the Covid-19 pandemic, these three sectors could survive. Thus the halal industry also contributes to Indonesian economy.

The second half of the 19th century in Galicia is a time of raised awareness about the significance of archives not only those being created at that time but also of the value of the materials concerning the history of Poland, first of all, the history of the local community. This fact was recognised by a circle of Galician researchers, scientists, historians and archivists from the Western Galician Conservators’ Circle. Since 1880s they undertook activities the aim of which was to save the archival heritage, e.g. by organising archival travels. In the years 1894–1911 they manages to organise 11 of such research trips. The subject of the present article based on source materials collected in the National Archive in Cracow focuses on presenting the organisational aspect of the travels and the related research works.
A contribution to the demographic characteristic of people who received the right of belonging to a gmina at the beginning of the 20th century (as illustrated by the cases of Lviv and Cracow)
Authors:   Uniwersytet Rzeszowski, Polska, Rejman Sabina
Published: January 2021

The article was based on the statistical data from “Wiadomości Statystyczne o Mieście Lwów” and “Statystyka Miasta Krakowa”. These sources can provide conclusions about groups which undertook migration, most often an internal one within the Austro-Hungarian Monarchy. The analysis of statistical data suggests that Cracow was a city more open to admitting migrants to its gmina and admitted them more than Lviv. Both cities preferred men, middle-aged or older, married couples, with means of support, Austrian citizens from Galicia. Cracow made more exceptions to this rule by admitting people from other countries of the Monarchy and foreigners. The Lviv councillors’ preferences were more conservative; however, in this city they decided voluntarily, while in Cracow, most people were admitted on the basis of the prescription of the right of belonging.
Pilgrimage movement in Galicia in the second half of the 19th century and at the beginning of the 20th century in the reports of the Galician press
Authors:   Uniwersytet Rzeszowski, Polska, Biesiadecka Elżbieta
Published: January 2021

The subject of the research undertaken in the article is the picture of pilgrimages of Galicians and the inhabitants of other partition in the Galician press. Pilgrimages constituted an important aspect of religious life in Galicia and in the second half of the 19th century they started to become mass events. Galician pilgrims travelled not only to holy places located within the partition but also courageously went on pilgrimages to Rome and the Holy Land. The authors of articles pointed out not only the religious dimension of the described Polish pilgrimages but also showed them as the opportunity to cultivate unity and the national tradition and to become more familiar with the national history.
The association between seropositivity to human toxocariasis and childhood asthma in northern Iran: a case-control study
Authors: Darvish Sorena , Mohammadzadeh Iraj , Mehravar Saeed , Spotin Adel , Rostami Ali
Published: January 2021

Background: Besides the well-known risk factors, Toxocara infection is thought to play a significant etiological role in the development of childhood asthma. To further explore this association, the prevalence of Toxocara infection in sera of asthmatic children and healthy controls in northern Iran was investigated.
Methods: In this case-control study, cases were 145 physician-confirmed asthmatic children diagnosed according to the Global Initiative for Asthma (GINA) guidelines. Controls were 115 age–sex–residence-matched children who did not have physician-diagnosed asthma. The presence of anti-Toxocara immunoglobulin G (IgG) was tested using enzyme-linked immunosorbent assay. Univariate and multivariate logistic regression methods were used for case-control comparisons.
Results: Seropositivity rate was 4.1% (95% CI, 3.4–4.7%) in asthmatic children and 0.86% (95% CI, 0.71–1.0%) in controls, suggesting a strong association (P-value < 0.02). Moreover, Toxocara infection was not significantly more prevalent (P-value = 0.12) in children with moderate sustainable asthma (9.3%, 3/32) than in children with mild sustainable asthma (2.3%, 3/113). Mean total immunoglobulin E (IgE) level was significantly higher in Toxocara-infected children (222.3 ± 367.1) than in non-infected children (143.19 ± 218.05) in the case group (P-value < 0.05).
Conclusions: Our findings indicated that Toxocara infection can play an important role in childhood asthma. Further experimental and epidemiological studies are needed to clarify this hypothesis.

Authors: Halil Celiksoy Mehmet , Hakan Ozmen Abdullah , Topal Erdem
Published: January 2021

Background: Papular urticaria is a hypersensitivity reaction characterized by chronic and recurrent papular erythema. It occurs as a result of the bites of mosquitoes, fleas, bed bugs, and other insects; and it is generally seen in children. This study examines the prevalence of atopic diseases in patients with papular urticaria.
Methods: The medical records of 130 pediatric patients with the diagnosis of papular urticaria between August 2017 and August 2019, whose disease progression was followed in two ter-tiary care centers, were reviewed retrospectively. The patients were divided into two groups: under 5 and above 5 years old. The prevalence of the atopic disease in children with papular urticaria was compared with those in age-matched controls without papular urticaria.
Results: The study included 130 patients who were diagnosed with papular urticaria (64 males, 66 females, median age: 60 months). The prevalences of atopic disease, recurrent wheezing, and atopic dermatitis were higher in the group under 5 years old with papular urticaria than in the same-age control group (p = 0.001, 0.002, and 0.001, respectively). The prevalences of atopic disease, asthma, allergic rhinitis, and atopic dermatitis were higher in the group above 5 years old with papular urticaria than in the same-age control group (p = 0.001, 0.001, 0.001, and 0.007, respectively).
Conclusions: Many children with papular urticaria are atopic children. These patients should be assessed not only in terms of papular urticaria but also in terms of comorbid atopic diseases.
Food allergy as an asthma comorbidity in children and adolescents: a practical approach through a real-world study
Authors: Esteban-Gorgojo Ignacio , Puy Gorgojo María , Sastre Joaquin , Quirce Santiago
Published: January 2021

Introduction: Several studies have shown interactions between food allergy (FA) and asthma, but the influence of FA in asthma traits has been scarcely studied.
Methods: A real-world retrospective observational study was conducted among patients between 3 and 18 years old referred to our Asthma Clinic from November 2014 to November 2017. Data were obtained from daily clinical practice. Only patients properly diagnosed with asthma and FA were included.
Results: 815 patients were included: 483 asthmatics and 332 non-asthmatics and 180 FA and 635 no FA. Food allergy was statistically more prevalent among asthma patients (p = 0.014). In a high pollen exposure area, Madrid, among subjects with asthma (121 FA, 362 no-FA), sensitization to lipid transfer protein (LTP) (p = 0.016, OR: 3.064, RR: 2.512) and pollen (p = 0.016, OR: 3.064, RR: 2.512) are risk factors to have a concomitant FA diagnosis, whereas sensitization to profilin is not. Peripheral blood eosinophils were higher in subjects with asthma and FA (≥450 eos/µL) than in asthmatics without FA (≤300 eos/µL) (p = 0.031). Blood eosinophilia, using a cut-off >300 eos/µL, was only present in the FA group. Therefore, this trait should be considered when phenotyping a patient as eosinophilic asthma. Sex had an impact on several variables: height, weight, BMI, blood eosinophils count, sensitization profile, and early-onset asthma.
Conclusions: Asthma and FA are closely related and the presence of FA should be investigated in every asthma patient. This study shows an association between asthma with concomitant FA and sensitization to pollen and LTP, blood eosinophilia, and growth alterations. Differences between boys and girls were also described, so a sex-specific approach is recommended.
Specific IgE levels as an outcome predictor in egg-allergic children
Authors: Rodríguez-Catalán Jesús , González-Arias Alba Manasa , Vallespin Casas Almudena , Río Camacho Genoveva Del
Published: January 2021

Background: Diagnosis of immunoglobulin E (IgE)-mediated egg allergy is often based on both a compatible clinical history and either elevated IgE levels or a positive skin prick test. However, the gold standard is the oral food challenge (OFC). Previous studies have pointed to a correlation between IgE levels and OFC outcomes.
Objective: This study aimed to determine the relationship between IgE levels and the outcome of OFC, seeking to establish cut-off OFC values that indicate a high likelihood of positive OFC results.
Methods: A total of 198 patients who underwent OFC (and a serological IgE antibody assay within the three preceding months) were reviewed and divided by OFC type (i.e., baked, cooked, or raw egg). IgE-specific levels were assessed against the challenge outcome as well as cut-offs proposed by other authors.
Results: Receiver-operating characteristic (ROC) curve analysis yielded a potentially useful ovomucoid IgE-specific cutoff used in OFC with cooked egg and several egg white and ovalbumin IgE-specific cut-offs for OFC with raw egg. We found no significant relationship between other specific IgE concentrations and the challenge threshold level with baked eggs.
Conclusions: IgE-specific concentrations are useful as predictors of OFC outcome and should be considered when selecting patients challenge testing with boiled or raw egg. However, patients should undergo OFC with baked egg regardless of IgE levels.

Published: January 2021

Objectives: The Asthma Risk Factor Scale (ARFS) is used to screen for asthma in Lebanese pre-school children (aged 3–16 years). The study objective was to describe factors associated with asthma, confirm ARFS score validity among Lebanese preschool children, and develop a risk score for asthma diagnosis in this age group (Pre-School Asthma Risk Factor Scale [PS-ARFS]). Methods: A cross-sectional study enrolled 515 preschool children (November 2018 and March 2019). The ARFS is a 15-item tool that assesses children’s environmental exposure, parental history of asthma, and dietary habits.Results: The percentage of asthmatic children was 8.2%. Higher odds of asthma in children were associated with living near a prairie sprayed with pesticides (odds ratio [OR] = 2.33), playing out-doors (OR = 2.89), having a heater in the bedroom (OR = 10.73), attending a nursery (OR = 2.91), having a mother who smokes cigarettes (OR = 3.35) or water pipe (OR = 2.46), a sister with a history of seasonal allergy (OR = 6.81), and a parental history (mother and father) of asthma (OR = 6.15 and OR = 9.83, respectively). Higher ARFS scores (OR = 1.144) were associated with higher odds of asthma. Accordingly, the PS-ARFS was created according to the following formula: ARFS score + (playing out-door × 2.4) + (heating system in the bedroom × 12.9) + (having attended a nursery × 2.5) (area under the curve = 0.908 [0.860–0.957]; P < 0.001); at value: 14.20, Se = 84.3% and Sp = 90.9%.Conclusion: PS-ARFS is suggested for screening of asthma in preschool children in an epidemiological setting and in the absence of spirometry.
CME suggestions for pediatricians, allergists, and dermatologists, directed by an online survey on urticaria knowledge
Authors: Pozo-Beltrán Cesar Fireth , Larenas-Linnemann Désirée , Cardoza Arteche Johanna Danielle
Published: January 2021

Background: The Mexican Guidelines for the diagnosis and treatment of urticaria have been published. Just before their launch, physicians’ knowledge was explored relating to key issues of the guidelines.
Objective: The aim of this study was to investigate the opinion of medical specialists concern-ing urticaria management.Methods: A SurveyMonkey® survey was sent out to board-certified physicians of three medical specialties treating urticaria. Replies were analyzed per specialty against the evidence-based recommendations.
Results: Sixty-five allergists (ALLERG), 24 dermatologists (DERM), and 120 pediatricians (PED) sent their replies. As for diagnosis: ALERG 42% and PED 76% believe cutaneous mastocytosis, urticarial vasculitis, and hereditary angioedema are forms of urticaria, versus DERM 29% (P < 0.005). Most of the specialties find that the clinical history and physical examination are enough to diagnose acute urticaria, except DERM 45% (P < 0.01). DERM 45% believe laboratory-tests are necessary, as opposed to <15% ALLERG–PED (P < 0.005). However, PED 69% did not know that the most frequent cause of acute urticaria in children is infections, versus ALLERG– DERM 30% (P < 0.005). Many erroneously do laboratory testing in physical urticaria and ALLERG 51%, DERM 59%, and PED 37% do extensive laboratory testing in chronic spontaneous urticaria (CSU); many more PED 59% take Immunoglobulin G (IgG) against foods (P < 0.005). More than half of non-allergists do not know about autologous serum testing nor autoimmunity (P < 0.05). As for treatment, there were a few major gaps: when CSU was controlled, >75% prescribed antihistamines pro re nata, and >85% gave first-generation antiH1 for insomnia. Finally, >40% of DERM did not know that cyclosporine A, omalizumab, or other immunosuppressants could be used in recalcitrant cases.
Conclusion: Specialty-specific continuous medical education might enhance urticaria management.

Authors: Zaryczański Janusz , Ochab Agnieszka , Ochab Magdalena , Zaryczańska Anna , Brzoza Zenon , Chobot Agata
Published: January 2021

Introduction: Urticaria is a clinical entity presenting as wheals, angioedema, or both simul-taneously. Elevated D-dimer levels were reported in the course of chronic spontaneous urticaria. Data regarding D-dimer levels in acute urticaria in children are limited.
Objectives: To assess potential associations between duration of glucocorticosteroid (GCS) therapy and D-dimer concentrations in children with acute urticaria.
Patients, materials, and methods: Hospital records of 106 children (59 females), aged 5.57 ± 4.91 years, hospitalized in 2014–2018 were analyzed retrospectively. The study group consisted of pediatric patients admitted to the hospital due to severe acute urticaria resistant to anti-histaminic treatment that was ordered in the ambulatory care (out-patient clinic). Patients were divided into subgroups: no GCS treatment, short-duration treatment (up to 5 days) and long-duration treatment (6 and more days) GCS treatment. Simultaneously, patients received antihistaminic drugs. D-dimer level and other inflammatory factors such as white blood cell (WBC) count, platelet (PLT) count, and C-reactive protein (CRP) in each group were analyzed.
Results: The D-dimer level was elevated in 51% of cases. In the subgroup with longer GCS treatment, D-dimer concentration was significantly higher in comparison to patients with a shorter GCS course. There were no differences in the distribution of CRP, PLT, and WBC concentrations between these subgroups.
Conclusions: In the studied group of children, there was a tendency for higher D-dimer levels in patients, who required a longer GCS treatment. This finding is hypothesis-generating and requires further investigation to confirm if D-dimers can be used as a prognostic factor in acute urticaria in children.

Published: January 2021

Background: The Global Asthma Network (GAN) builds on the International Study of Asthma and Allergies in Childhood (ISAAC).
Objective: To compare asthma prevalence time trends in primary and secondary school children in four Mexican centers participating in ISAAC and GAN.
Methods: GAN is a cross-sectional, multicenter, epidemiological methodology carried out in groups of primary school children aged 6–7 and adolescents aged 13–14 following the ISAAC Phase Three protocol, with additional questions on risk factors and asthma management.
Results: Overall, the prevalence of asthma symptoms and diagnosis in primary school children was higher in males than in females both in ISAAC (p < 0.05) and in GAN (p < 0.01), while adolescent females had a higher prevalence, also both in ISAAC (p < 0.001) and in GAN (p < 0.001).
Conclusion: The prevalence of asthma and its symptoms has increased from ISAAC Phase Three since 2003 to GAN Phase I in Mexico in 2019. These findings are in line with the increases observed in the centers with low asthma baseline prevalence in ISAAC Phase One in comparison with ISAAC Phase Three.

Background: Spain has been severely affected by the COVID-19 epidemic, with 195,944 persons infected and 20,453 deaths at the time of writing. Older people with respiratory or cardiac conditions are most at risk.
Objective: The aim was to compare respiratory symptoms in nursing home residents and patients with uncontrolled asthma, who are considered vulnerable to COVID-19.
Methods: We studied 134 nursing home residents and 139 patients with uncontrolled asthma, groups vulnerable to COVID-19. Demographic characteristics, clinical manifestations, outcomes, key laboratory results, and radiological images were collected from medical records. COVID-19 infection was detected by polymerase chain reaction (PCR).
Results: Thirteen (9.3%) patients with uncontrolled asthma, all receiving inhaled corticosteroids were infected by COVID-19. Eighty (60%) nursing home residents were infected; only 28, all of whom had received inhaled corticosteroids, had a good prognosis.
Conclusions: Early treatment with inhaled corticosteroids may be helpful in COVID-19 infection. Persons with an allergy might have some protective mechanisms against coronavirus.

Published: January 2021

Abstract Acknowledging the relevance of mathematics education, as well the evidence about predictors related to achievement in this domain, the present study performed a predictive analysis of students’ mathematics achievement in the National Exam for Secondary Education, employing the Regression Tree Method and a model with 53 predictors. Results indicated that the model explained 29.97% of the mathematics achievement variance. Certain variables are related to worse achievement in mathematics: Students’ family monthly income equal or smaller than 2 minimum wages, be female, have not attended Primary and Secondary Education in private schools, live in North, North East and Center West regions of Brazil, be highly motivated to perform the exam to obtain Secondary Education certificate or scholarship. The results obtained highlight the role of variables related to the individual, school and family as predictors of mathematics achievement.

Published: January 2021

Objective: to perform the psychometric validation of the Brazilian version of the Patient Dignity Inventory (PDI – Br) in patients with advanced diseases in palliative care. Method: a methodological study to verify the psychometric properties of the Patient Dignity Inventory (PDI – Br) instrument, through validity and reliability tests. Results: the exploratory factor analysis showed a factorial solution with three factors, responsible for 40.9% of the explained variance, with adequate internal consistency for the Presence of Symptoms (α=0.859), Dependence (α=0.871), and Existential Suffering (α=0.759) domains. The test-retest was performed and indicated moderate to strong correlations. Convergent validity demonstrated a positive correlation between the Presence of Symptoms and the sadness (r=0.443) and anxiety (r=0.464) variables. Weak negative correlations were observed between the PDI – Br domains and functionality, spiritual well-being and quality of life. Conclusion: composed of three domains and 25 items, the PDI – Br instrument presented satisfactory psychometric properties for its use in our environment, through the evidence of validity and reliability.

Resumo Objetivo Identificar preditores do conhecimento inadequado sobre medicamentos prescritos a pacientes ambulatoriais muito idosos e seus cuidadores. Método O conhecimento sobre os medicamentos prescritos para 80 pacientes com 80 anos ou mais de idade foi avaliado por meio de um questionário validado, em uma entrevista realizada com os pacientes ou seus cuidadores (quando os pacientes apresentavam dificuldades de comunicação, demência ou qualquer necessidade de assistência para ajudá-los a usar medicamentos). Dois modelos de regressão logística hierárquica avaliaram a associação entre conhecimento inadequado sobre medicamentos e variáveis sociodemográficas e medicamentosas. Resultados Trinta e nove (48,8%) entrevistados eram cuidadores. Conhecimento inadequado foi encontrado em 81,5% (404/496) dos medicamentos prescritos. Forma de administração, Dose, Frequência e Duração do Tratamento foram os aspectos de maior conhecimento, enquanto Reações Adversas, Precauções, Interações e Contraindicações, os de menor.

Abstract: The objective of this work was to evaluate the potential of the stable isotope technique to characterize beef cattle production systems in tropical conditions. For this, carbon and nitrogen stable isotopes were identified in non-defatted and defatted bovine muscles. A total of 45 cattle were evaluated in three production systems: pasture, conventional feedlot, and young beef bull feedlot (n = 15 per system). Samples from the Trapezius cervicis, Longissimus dorsi, and Semitendinosus muscles were collected to determine the isotopic composition of δ13C and δ15N. The isotopic data of the δ13C and δ15N of non-defatted and defatted muscles were subjected to the principal component analysis (PCA) and to the discriminant analysis (DA). The PCA allowed separating the three production systems based on the results obtained for the non-defatted and defatted muscles. A correct global classification rate of 100% and a cross-validation rate of 100% were obtained with the DA. The carbon and nitrogen isotopic ratio of non-defatted and defatted muscles allows for the precise identification of beef cattle production systems in tropical conditions.

Abstract: The objective of this work was to evaluate the qualitative parameters and nutritional potential of silage of arboreal cotton (Gossypium hirsutum) shoots. The experiment was carried out in a 4×2 factorial arrangement, for two silage forms (in natura or pre-dried), with four treatments, as follows: without additives (WA); with inoculant (WI); with 2% ground corn (GC); and with 2% ground corn with inoculant (GC+I). The fermentative quality and nutritional parameters of the silages were evaluated. Fermentative quality was better in the WI and GC+I silages. The dry matter content was higher in the pre-dried silage, while the crude protein contents of in natura silage were higher in the WA and WI treatments. The lowest values of neutral detergent fiber and acid-digested lignin were observed in the WI treatment, for pre-dried silage. Total digestible nutrients and total volume of gas were higher in the pre-dried silage, in the WI and GC treatments, respectively. In vitro dry matter digestibility was lower in WA silage, in both forms. Silage of arboreal cotton associated with inoculant or with inoculant with ground corn shows a better fermentation profile and improves the energy and nutritional values, both in natura and pre-dried forms; however, in natura silage is less laborious for rural producers.

Abstract: The objective of this work was to evaluate the physicochemical properties of Colombian cape gooseberry (Physalis peruviana) hybrids and to select those with the highest fruit quality based on a selection index. A total of 36 cape gooseberry hybrids obtained from crossings between nine double haploid lines from the Tibaitatá Research Center of Colombian Corporation for Agricultural Research were evaluated. The trials were conducted in a randomized complete block design, in four locations (environments), corresponding to the municipalities of Ipiales, Gualmatán, Puerres, and Pasto, in the department of Nariño, Colombia. The following variables were evaluated: cracking percentage (CP), fruit weight with calyx (FWC), juice content (JC), total titratable acidity (TTA), total soluble solids (TSS), maturity index (MI), firmness (F), ascorbic acid (AA), and respiration rate (RR). CP was affected by the environment, showing lower values in Ipiales, Gualmatán, and Puerres. The hybrid factor significantly affected all assessed variables, except RR. The selected hybrids showed higher values for TSS, MI, FWC, and AA, besides lower values for CP and RR. The 3x9 hybrid stands out for presenting averages that are high for AA (42.59 mg 100 g-1) and MI (7.91) and low for RR (49.2 mg CO2 kg-1 h-1).

Published: January 2021

Resumo Este trabalho descreve o emprego de cinza ultrafina da casca de arroz com elevado teor de carbono em concretos de resistência convencional e de alta resistência. Estudou-se a influência do emprego da cinza ultrafina (10%, 15% e 20% de substituição de cimento, em massa) nas propriedades reológicas (tensão de escoamento e viscosidade plástica), na resistência à compressão (7, 28, 90 e 180 dias) e na penetração acelerada de íons cloreto. Além disso, a elevação adiabática da temperatura de um concreto convencional com 15% de cinza ultrafina foi comparada com a elevação de um concreto de referência. Os resultados indicaram que a cinza ultrafina produz melhorias significativas nas propriedades dos concretos para ambas as classes de resistência.

Published: January 2021

Superintelligence is a hypothetical agent that possesses intelligence far surpassing that of the brightest and most gifted human minds. In light of recent advances in machine intelligence, a number of scientists, philosophers and technologists have revived the discussion about the potentially catastrophic risks entailed by such an entity. In this article, we trace the origins and development of the neo-fear of superintelligence, and some of the major proposals for its containment. We argue that total containment is, in principle, impossible, due to fundamental limits inherent to computing itself. Assuming that a superintelligence will contain a program that includes all the programs that can be executed by a universal Turing machine on input potentially as complex as the state of the world, strict containment requires simulations of such a program, something theoretically (and practically) impossible.

Published: January 2021

In current situation, the widespreading of the COVID-19 pandemic in the world has had a significant impact on the socio-economic development of our country. To minimize the effects of this impact, it is necessary to restore the country's strong economic potential through the efficient use of the country's existing natural and labor potential. In such situation the focus should be on improving the functioning of natural monopolies and adapting them to changing market requirements. Natural monopolies play a special role in the formation and dynamic development of the market economy, enriching the domestic market with products based on local raw materials, improving the living standards of the population, creating new jobs and increasing the level of employment and solving other socio-economic problems. Natural monopolies in Azerbaijan exist mainly in the areas of heat and electricity transmission, natural gas and oil pipelines, railway transport, ports, terminals and airport services. Prices for products in this area are also objects of state regulation. Regulation of prices for natural monopolies is important in solving the country's social and economic problems, increasing the competitiveness of products produced in the national economy and the sustainable development of the country as a whole.Therefore, there is a need to analyze the specifics and mechanisms of state regulation of the activities of natural monopolies. In solving all these problems, there is a special need to pay constant attention to the organization of the activities of natural monopolies in terms of modern requirements, to increase their production capacity and thus to determine their impact on the national economy. The mentioned features show the relevance of the topic of the article.

At present, when the country has successfully implemented a cluster policy since 2010, which contributes to increasing the competitiveness of both regions and individual industries, the impact of industry clusters on the main economic indicator is an extremely relevant and important issue. Of course, basically, when we talk about clustering, we are talking primarily about industrial network structures. However, given the need for social transformations in the country and improving the quality of life of the population, it is necessary to know how the development of the socioeconomic cluster in the housing and utilities sector will affect the level of economic development of the region and the country as a whole. The article discusses the possibility of using correlation-regression analysis to predict the gross regional product (GRP) depending on the factors that are significantly influenced by the housing and utilities sector. These factors, in our opinion, include “The volume of shipped goods of our own production, works and services performed on our own by type of activity”, “The volume of work performed in the type of economic activity“ Construction ”,“ Investments in fixed assets ”,“ Final consumption ”, etc. The calculations were carried out for the Sverdlovsk region. To predict the GRP indicator, the authors used two-factor models. The obtained mathematical models confirm the significant impact of all considered factors on the performance indicator. As a result of the calculations, it can be noted that the gross regional product increases by an average of 102 million rubles. excluding the indicator of the volume of own production only due to the volume of construction and installation work. The gross regional product decreases by an average of 94,560 million rubles. excluding the indicator of investments in fixed assets due to the indicator "final consumption of the Sverdlovsk region" and increases by 5.56 million rubles. through investments in fixed assets of the Sverdlovsk region. Thus, the most significant factor influencing the region's GRP is the “Final consumption in the Sverdlovsk region” factor, which means that the proposed mathematical models will be able to adequately assess the impact on the region’s GRP of the activity of the socio-economic cluster in the housing sector, since the population's expenditures on Housing and utility services of the Sverdlovsk region make up about 28-35% of all consumed services and affect the final consumption of the region's population, especially in the context of constantly growing tariffs in this area.
