Association between companion animal ownership and overall life satisfaction in Seoul, Korea
Authors: Kim Jeehyun , Chun Byung Chul
Published: September 2021

This study aimed to analyze the association between companion animal ownership, the sub-factors of this ownership (the species and number of owned pets), and overall life satisfaction (OLS). Data was obtained from the publicly available responses to the 2017 Seoul Survey, conducted among Seoul-based Korean locals aged ≥ 15 years (N = 42,687; pet owners = 8,708, non-owners = 33,979). Propensity score was calculated by performing logistic regressions with covariates and data was matched using the nearest-neighbor method. Further, multiple linear regression was performed to analyze this association using the matched data. Additionally, survey-weighted multiple regressions were performed: 1) within pet owners, and 2) after stratifying owners with the number of pets owned. Pet owners in Seoul, South Korea reported higher levels of OLS than non-owners, even after controlling for covariates—age, sex, marital status, family size, family income, job, education, types of housing, housing tenure. Owners with both dogs and cats showed the highest average OLS scores (owners with 2 pets: Mean [M] = 58.05, Standard Deviation [SD] = 0.67; owners with ≥ 3 pets: M = 59.03, SD = 1.02), followed by single pet owners of either a cat (M = 56.64, SD = 0.37) or a dog (M = 56.14, SD = 0.13). Single pet owners reported significantly higher levels of OLS than those with 2 or ≥ 3 pets when pet types were adjusted for. When owners had a single pet, pet types (dog or cat) did not generate a significant difference in OLS scores. Among owners with 2 or ≥ 3 pets, however, owners with both dogs and cats had higher OLS scores than dog owners. This research has significant implications for promoting future study on companion animal effects for improving human health and well-being. Mechanisms of the effect, including cultural factors, should be further investigated.

Published: September 2021

In this work, the quantum computations of newly synthesized N-(4-hydroxyphenyl)picolinamide
(4-HPP) is focused. Density functional theory (DFT) was used to perform the quantum calculations.
The optimized molecular geometry was obtained using the B3LYP and MP2 methods employing
6-311++G(d,p) basis set, which served as the foundation for all subsequent calculations. The
experimental data was compared with the calculated vibrational frequencies and NMR spectra. With
the use of the molecular electrostatic potential surface (MEP) and the Fukui functions, the charge
distribution, reactive regions and electrostatic potential were displayed. The chemical activity of the
4-HPP was evaluated by the energy difference between HOMO and LUMO. For better understanding
of the intermolecular charge transfer (ICT), natural bond order analysis (NBO) was used. At various
temperatures, thermodynamic parameters such as Gibb’s free energy, enthalpy and entropy were
determined. The electrophilicity index was used to portray the molecule’s bioactivity and molecular
docking was used to show the interaction between the ligand and the protein. The nature of the molecule
was determined by drug similarity when expecting its application for medical purposes.

Maternal and Foetal Outcome in Pregnancy with Heart Disease Admitted in Chalmeda Anand Rao Institute of Medical Sciences, Karimnagar
Authors: Kavitha Veladanda , Niharika Chungi
Published: September 2021

BACKGROUND Heart disease complicating pregnancy is considered as a high-risk condition. Increased cardiac demands during the course of pregnancy potentially increase morbidity and mortality in women with underlying heart disease. Fifty percent increase in volume of plasma and increase in the risk of thrombosis by 6 times strikes a challenge to pregnant woman with heart disease. Pregnancy state is more prone to risk of infection as it is an immunocompromised condition which can result in increased heart rate eventually deteriorating the cardiac function. We wanted to determine maternal and foetal outcome in pregnant women with heart diseases in terms of foetal complications, maternal complications, and mode of delivery. METHODS A prospective clinical study conducted in Chalmeda Anand Rao Institute of Medical Sciences, Karimnagar for delivery was carried to find out the maternal and foetal outcomes in about 30 cases of pregnancy complicated heart disease. Taking prevalence to be 4 % (P) with confidence interval of 95 % (Z = 1.96) and allowable error (d) 7 %, sample size was calculated using formula 𝑍 2𝑃𝑄/𝑑2 RESULTS Present study revealed heart disease in pregnancy as about 0.48 %. Rheumatic heart lesions constituted 56.6 % of the cases. Eleven (36.7 %) women delivered spontaneously vaginally at term. Caesarean section was performed in 12 cases (41.2 %). There were 2 maternal deaths. No perinatal deaths were reported. CONCLUSIONS Pregnancy and cardiac lesions affect mutually. Compliance of patient and her family to regular follow up will ensure a safe outcome for mother and foetus and avoid complications by regular checkups with obstetrician and cardiologist.

Effects of Nalbuphine and Fentanyl as Adjuvants to (0.5 %) Isobaric Levobupivacaine in Subarachnoid Block for Elective Transurethral Endoscopic Surgeries
Authors: G Dinesh , G.B Shilpa , Murdeshwar Greeshma N.
Published: September 2021

BACKGROUND Isobaric levobupivacaine has minimal effect on positional variation of sensory and motor blockade given intrathecally. Also, it has lesser cardiotoxic and neurotoxic effects. Present study was done to compare efficacy, analgesia haemodynamic effects and any adverse effects after spinal anaesthesia with isobaric levobupivacaine with nalbuphine and fentanyl as adjuvants in transurethral endoscopic surgeries. METHODS 60 male adult patients of American Society of Anaesthesiologists (ASA class I-III) of age group 40 - 80 years were randomized into 2 groups (n = 30) in this prospective, double blinded study. 10 mg of 0.5 % levobupivacaine with 25 µg fentanyl in group LF and 10 mg of 0.5 % levobupivacaine with 0.8 mg nalbuphine in group LN. Parameters assessed were sensory and motor blockade characteristics and hemodynamic variables in both the groups. Adverse effects were recorded if any. RESULTS Onset of sensory and motor blockade were significantly faster in group LF compared to group LN. In both the groups, time for two segment regression was comparable. Statistically significant prolonged analgesic duration was noticed in group with nalbuphine than fentanyl as adjuvant to isobaric levobupivacaine. Difference in haemodynamic variation was not significant in both the groups. CONCLUSIONS Intrathecal nalbuphine 0.8 mg as an adjuvant with isobaric levobupivacaine 0.5 % 10 mg is as efficacious as fentanyl 25µg in transurethral endoscopic surgeries in elderly population with better hemodynamic stability.

Authors: Jujjavarapu Snehaja , Anselmo Peres Karen Glazer DE , Brennan David
Published: September 2021

BACKGROUND Oral health and general health are very closely related and are considered to be important health problems among individuals due to their expenses associated with treatment, prevalence rate and impact level among individuals and adolescents. These investigations can even have key suggestions for general and oral health prevention strategies relevant to the present knowledge on risk factors for these conditions. Assessment of the current impacts of oral health conditions on quality of life might even develop an understanding of the importance of dental conditions. The general purpose of the current thesis was to investigate the association between oral health and its impact on oral health-related quality of life (OHRQoL) among Brazilian adolescents. METHODS A population-based birth cohort study was carried out in the urban city of Pelotas, Brazil, in the year 2004 (2004 PBCS), including all live births in the city. All mothers living in the urban area of Pelotas and their children born in maternity hospitals of the city of Pelotas (N = 4231) were eligible to participate in this study. RESULTS Findings presented in this thesis indicate that a negative association between oral conditions and OHRQoL exists. Adolescents with severe malocclusion identified with a DAI score greater than 36, showed a negative impact on OHRQoL. Individuals with the presence of dental plaque were seen suffering from severe malocclusion, which in turn was negatively associated with OHRQoL. The evidence provided by the current thesis may not only contribute primarily to the scientific literature but may also furnish researchers and epidemiologists with information vital for orthodontic treatment and be useful to identify community needs and help in the implementation of treatment plans. CONCLUSIONS In conclusion, the impact of malocclusion on daily events among adolescents of Brazil was a common finding in our study. Some other important variables like gingival status, schooling of the fathers that possibly act during childhood which might be affecting the QoL were not included in our present study. These findings may not only contribute to the literature but may also furnish researchers and epidemiologists with information vital for orthodontic treatment and use to identify the community needs and help in the implementation of the treatment plan. Further studies need to be developed to clarify the most complex relationship between impacts of malocclusion on QoL.

Versatility of Buccal Pad of Fat in the Reconstruction of Oral and Maxillofacial Defects - A Review
Authors: Samson Jimson , Pandurangan Pandiyarajan , Balasubramanian Anandh , Jayabalan Jones
Published: September 2021

BACKGROUND The maxillofacial region has several congenital and acquired defects. Because of its abundant blood supply and proximity to different intraoral abnormalities, the buccal fat pad flap (BFP) is a simple and reliable flap that can be used to repair a variety of these abnormalities. BFP has remarkable qualities as a scaffold and autogenous dressing in the healing of intraoral defects after excision of oral cavity intraoral lesions. Filling and allowing slippage of fascial spaces between muscles of facial expression, advancement of intermuscular motion, isolating mastication muscles from one another, counteracting negative pressure during suction in the newborn, protection and cushioning of neurovascular bundles from injuries are among the functions of BFP. It also has a dense venous network that facilitates exoendocranial blood flow via the pterygoid plexus. For many years, the BFP was considered a surgical annoyance due to its incidental encounter during various surgeries in the pterygomaxillary space or following injuries to the craniofacial region. However, various clinical applications of BFP have been introduced in recent years. We looked at BFP and its anatomical foundation, surgical procedures, and clinical applications in this review article. The surgical method is easy and effective in a wide range of clinical situations, including oroantral fistula closure, congenital defect rectification, Osteoradionecrosis treatment, and reconstruction of tumor or cyst defect. Thus BFP is a dependable flap that may be used in a variety of therapeutic conditions. KEY WORDS Buccal Fat Pad Flap; Oral Mucosa; Reconstruction; Defect.
Cardioprotective mechanisms of sodium-glucose cotransporter 2 inhibitors
Authors: Mkrtumyan A. M. , Markova T. N. , Mishchenko N. K.
Published: September 2021

The findings of large-scale cardiovascular outcome trials have been demonstrated that sodium-glucose cotransporter 2 ­inhibitors (iSGLT-2) have shown beneficial cardiovascular effects. In this review proposed mechanisms underlying iSGLT-2-associated cardiovascular benefits have been discussed: haemodynamic and intracellular effects, including metabolic effects and electrolyte changes; and also, the effect on markers of cardiovascular disease (CVD). The hemodynamic effects of SGLT-2 are characterized by reduction of cardiac preload and afterload as a result of osmotic diuresis, a decrease in blood pressure and arterial stiffness. The metabolic effects of this medicine are accompanied by an increase the production of ketone bodies, followed by improving ATP production and myocardial energetics. Also, iSGLT-2 modulate ion transporters (NHE1 and NHE3). A reduction of cytoplasmic sodium and calcium levels and increasing mitochondrial calcium levels in the cardiomyocytes enhances the synthesis of ATP and increases cell viability. Effect of iSGLT-2 on CVD markers showed a decrease in the levels of the N-terminal pro-B-type natriuretic peptide and highly sensitive troponin I in elderly patients with type 2 diabetes mellitus (T2DM). Thus, this class of agents has a multifactorial effect on the functioning of cardiovascular system. Further studies will help to explain the all possible cardioprotective effects of iSGLT-2 in individuals with and without T2DM.
The influence of external environment on workers on scaffolding illustrated by UTCI
Authors: Szer Iwona , Szer Jacek
Published: September 2021

The aim of the article was to present the influence of the external environment on people working on scaffolding. For this purpose, the heat load of a man was determined using the universal thermal climate index. The research was carried out on 40 facade scaffolds located in four voivodeships in Poland: Lower Silesia, Lublin, Lodzkie, and Masovian. The conducted analysis showed that employees may experience strong or very strong heat stress, and also extreme heat stress in isolated cases. The highest probability at 0.30 level occurs on scaffolds located in the Lodzkie voivodeship. Environmental conditions are therefore unfavourable for people working outside. This can lead to reduced concentration, longer reaction time, and greater fatigue, contributing to an increase in situations that could lead to accidents. Hazard identification allows to take safety measures that improve the comfort of work on scaffolding.

Published: September 2021

Objectives

Sexual dysfunction can adversely affect the quality of life and interpersonal relationships. nowadays, a lot of attention is paid to traditional Chinese medicine with better curative effects and less adverse events. Recent studies have implied the promising effect of acupuncture on sexual function. This systematic review evaluate the effectiveness and safety of acupuncture in treating female and male sexual dysfunction.

Content

PubMed, Cochrane Central of Controlled Trials (CENTRAL), EMBASE, Web of Science, China National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Database (CBM), Scopus, and Google Scholar were searched up to 2021. No limitation to language and date. The methodological quality of the studies was assessed using the Mixed Methods Appraisal Tool (MMAT).

Among 160 initially assessed papers, 13 articles were included. The findings showed that acupuncture improve sexual dysfunction in domains of desire, libido, erectile dysfunction and impotency. Most studies did not report any serious side effects from acupuncture, and only three studies reported minor adverse events.

Outlook

The available evidence indicate that acupuncture has positive on improvement of sexual dysfunction with no serious side effects. Although acupuncture has gained increasing popularity for the management of sexual dysfunction, high methodological quality evidence regarding its efficacy is lacking.
Developing strategies for conceptual accessibility through multimodal literacy in the English for tourism classroom
Authors: Bonsignori Veronica , Cappelli Gloria
Published: September 2021

Teaching English for Tourism at university involves both developing specialized language skills and forming knowledgeable professionals capable of appropriate intercultural communication. The distinctive feature of most instances of tourism discourse is the fact that it draws from a range of specialized domains. It mediates the tourist experience and contributes to closing the gap between the home- and the destination’s culture by making culture-specific knowledge and specialized concepts accessible to non-specialists. The article discusses the instructional effects of authentic multimodal materials within task-based project-work carried out with learners at the University of Pisa. The focus is specifically on the communicative strategies used to make specialized terminology or concepts easily understandable for the hearer. This study reports on a multimodal analysis of two sets of videoclips created by the students before and after dedicated instruction based on authentic English L1 clips from documentaries, “docu-tours” and guided tours. It discusses the positive changes observed in the learners’ use of popularization strategies to create conceptual accessibility.

Between spatial domain and grammatical meaning: The semantic content of English telic particles
Authors: Konieczna Ewa
Published: September 2021

The purpose of this article is to demonstrate that English spatial particles which have grammaticalised into telic aspectualisers are not devoid of the image schematic content, which motivates their use in specific contexts. Because aspectual meaning, including telicity, is compositional in nature, which means that it frequently results from the interaction of several linguistic features, it is vital to single out those predicates in which the telicity effect can be attributed solely to the particle, not any other elements of the construction. This can be implemented by adopting the scalar approach, which shows that telicity is entailed by the particle exclusively in a predicate containing an incremental theme verb. Accordingly, the incremental theme verbburnand its five telic particles (up,down,out,offandaway) constitute the subject of investigation. The analysis demonstrates that each particle encodes telicity in terms of reaching the GOAL in the SOURCE-PATH-GOAL schema. Conceptual differences in encoding the termination of the burning process result from topological properties of the path construed by each particle under study.

Published: September 2021

This paper presents a modification of the theory of weighted mean temperatures for rivers. Rodhe, B. (1952) assumed the dominance of sensible heat transfer on ice formation. We aimed to improve the method for the evaluation of ice and water temperature based on a relatively low number of inputs. We further developed the model by introducing the effect of pre-existing ice, hence increasing the accuracy of the model on the timing of ice disappearance. Prediction accuracy of ±1 day was reached for the timing of the appearance of ice. Additional outputs have also been added to the model, including the termination of ice and the prediction of water temperature. The temperature calculation had a coefficient of determination of 95 percent, and a root mean square error of 1.33 °C during the calibration period without the use of observed water temperatures. The validation was carried out in a forecasting situation, and the results were compared to the energy balance.

The use of thematic cartography in earth sciences is a frequent task for researchers when publishing. When creating a map, researchers intend to communicate important spatial information that enhances, supplements or replaces textual content. Not only visual but substantial requirements exist for those who create maps. Cartographic visualisation has several well-established rules that must be taken into account during compilation, but not all researchers apply them correctly. The present study aims to identify the factors determining the quality of geoscientific maps and what needs to be improved during a map compilation process. To get to know the tendencies, we have investigated maps in designated journals – one Hungarian and one international per earth science branch: geography, cartography, geology, geophysics, and meteorology. A system of criteria was set up for evaluating the maps objectively; basic rules of cartography, quality of visual representation, and copyright rules were investigated. The results show that better map quality is connected to journals with strict editorial rules and higher impact factors. This assessment method is suitable for analysing any kind of spatial visual representation, and individual map-composing authors can use it for evaluating their maps before submission and publication.
Comparison of Microplegia Solution and Del Nido Cardioplegia Solution in Coronary Artery Bypass Grafting Surgery: Which One is More Effective?
Authors: Urcun Yusuf Salim , Pala Arda Aybars
Published: September 2021

Background: The aim of this study is to compare the efficacy of the microplegia solution and Del Nido cardioplegia solution in coronary artery bypass surgery with clinical, biochemical, and echocardiographic data.
Methods: Three hundred patients, who underwent coronary artery bypass surgery between January 2017 and January 2020, by the same surgical team were included in the study. Preoperative, operative and postoperative data (cardiac biomarker levels, cross-clamp and CPB times, echocardiographic measurements, etc.) of the patients were compared.
Results: In the study, cross-clamp time was significantly shorter in the DN cardioplegia group (55.60 ± 13.49 min/75.58 ± 12.43 min, P = 0.024). No significant difference was observed between the two groups in terms of intensive care stay, extubation time, hospital stay, and cardiopulmonary bypass time. In our study, it was shown that both the left and right ventricular ejection fraction was better protected in the Del Nido cardioplegia group (5.34±3.03 vs. 3.40±2.84, P = 0.017 and 3.82±1.19 vs. 2.28±1.87, P = 0.047, respectively), and the need for inotrope support was lower in this group (28% vs. 44%, P < 0.021). There was no significant difference between the groups, in terms of blood transfusion rates, IABP requirement.
Conclusion: In light of short-term results, we can say that Del Nido cardioplegia provides better myocardial protection than microplegia. In addition, Del Nido cardioplegia can be given as a single dose for 90 minutes of cross-clamp time and therefore can be preferred to increase surgical comfort and reduce cross-clamp times.
Child Sexual Abuse Recurrence: A Narrative Review
Authors: Wildfeuer Rachel , Kobulsky Julia , Reyes José
Published: September 2021

Child sexual abuse recurrence can have a detrimental and devastating effect on victims. Less is known, however, about the risk and protective factors associated with child sexual abuse recurrence. In order to better understand these risk and protective factors, a narrative review was conducted of the current literature. Academic databases, cited references, and reference lists were searched for peer-reviewed research that focused on sexual abuse recurrence prior to age 18 years. The risk and protective factors identified in the literature were organized into four a priori categories based on an ecological systems framework: child, characteristics of the maltreatment, family, and community/social systems. Examples of risk factors at each level were child mental health concerns (child), the perpetrator being the mother’s significant other (characteristics of the maltreatment), parental history of sexual abuse (family), and active or prior child welfare involvement (community/social systems). Only two protective factors were identified, both regarding the family: family social support and a parent believing the child’s report of the initial victimization. There were mixed or inconclusive findings for several factors. Overall, the review indicates that tertiary prevention, including child-, caregiver-, and perpetrator-focused strategies, should be employed to mitigate the risk factors and enhance the protective factors for child sexual abuse recurrence. Further research is needed to address protective factors and community/social systems factors and could, building on this narrative review, involve a systematic review of the child sexual abuse recurrence literature.

Authors: Wu Yahua , Yin Xinyue , Li Jie , Qian Shiquan
Published: September 2021

A water-soluble polysaccharide from Chaenomeles lagenaria (CLWSP-1) was purified and structurally identified. Then, response surface methodology (RSM) was performed to optimize the hot water extraction (HWE) of CLWSP-1. In addition, the antibacterial activity of CLWSP-1 was also evaluated. The results indicated that the polysaccharide CLWSP-1 mainly contained galacturonic acid, arabinose, and galactose, and its molecular weight was 1.23 × 102 kDa. The optimal HWE for extraction of CLWSP-1 was a ratio of water to solid of 48.9 mL/g, temperature of 91 °C, and an extraction time of 114 min; an ethanol concentration of 81% and a 1.24% concentration of CLWSP-1 were achieved. Moreover, the obtained CLWSP-1 had strong antibacterial activity when exposed to Escherichia coli and Staphylococcus aureus, suggesting that CLWSP-1 may potentially contribute to the development of a natural preservative in the food industry.
A relativistic theory of the field
Authors: Valenzuela Mississippi
Published: September 2021

As gravitation and electromagnetism are closely analogous long-range interactions, and the current formulation of gravitation is given in terms of geometry, we expect the latter also to appear through the geometry. This unification has however, remained an unfulfilled goal. Thence emerges a relativistic theory of the asymmetric field by generalization of the general relativity. It will demonstrate in a new way that the field-equations chosen for the non-symmetric fields are really the natural ones.

Objective Although fluid resuscitation is the cornerstone of treatment for sepsis, the role of body water status in sepsis is poorly understood. This study aimed to understand how body water and its distribution are modified in patients with sepsis and those with non-septic infection compared to healthy individuals.Methods Two groups of adults presumed to have non-septic infection (n=87) and sepsis (n=54) were enrolled in this prospective study in a single emergency department, and they were compared to sex-, age-, and height-matched (1:3 ratio) healthy controls (n=11,190) from retrospective data in a health promotion center. Total body water (TBW), intracellular water (ICW), and extracellular water (ECW), determined using direct segmental multi-frequent bioelectrical impedance analysis (InBody S10) were expressed as indices for normalization by body weight (BW). The ratio of ECW to TBW (ECW/TBW) was evaluated to determine body water distribution.Results TBW/BW, ICW/BW, and ECW/BW were significantly higher in the non-septic infection group than in the healthy group (P<0.001), but ECW/TBW was not significantly different (P=0.690). There were no differences in TBW/BW and ICW/BW between the sepsis and healthy groups (P=0.083 and P=0.963). However, ECW/BW and ECW/TBW were significantly higher in the sepsis group than in the healthy group (P<0.001).Conclusion Compared to the healthy group, the ratio of body water to BW was significantly increased in the non-septic infection group, while ECW/BW and ECW/TBW were significantly increased in the sepsis group. These indices could be utilized as diagnostic variables of body water deficit in septic patients.
A demographic perspective on human wellbeing: Concepts, measurement and population heterogeneity
Authors: Spitzer Sonja , di Lego Vanessa , Greulich Angela , Muttarak Raya
Published: September 2021

This introduction to the 2021 special issue of the Vienna Yearbook of Population Research explores demographic perspectives on human wellbeing across time and space. While the idea of relating demographic parameters to wellbeing has been around for a while, a more concrete research agenda on this topic has only recently gained momentum. Reviewing the research presented in this volume, we show how existing theoretical concepts and methodological tools in demography can be used to make substantial advances in the study of wellbeing. We also touch upon the many challenges researchers face in defining and measuring wellbeing, with the most important debate being about whether the focus should be on objective or subjective measures. The studies discussed here define wellbeing as health and mortality; as income, education or other resources; as happiness or life satisfaction; or as a combination thereof. They cover wellbeing in historical and contemporary populations in high- and low-income countries, and also point out important barriers to research on wellbeing, including the lack of good quality data in many regions. Finally, we highlight the value of considering population heterogeneities when studying wellbeing in order to identify population subgroups who are likely to fall behind, which can have important policy implications.

Os indicadores de qualidade no contexto da educação especial são ferramentas essenciais para avaliar, analisar, acompanhar e aprimorar o atendimento oferecido aos alunos da educação especial. Embora não seja sinônimo de educação especial, para a UNESCO, a educação inclusiva se baseia no direito de todos a receber uma educação de qualidade que atenda às suas necessidades de aprendizagem, portanto, seus significados convergem. Diante disso, este trabalho, com base no método SSF (Systematic Search Flow), realizou uma revisão sistemática da literatura para identificar os componentes destacados como relevantes para avaliar a qualidade da educação especial na perspectiva da educação inclusiva.Como resultado, foram identificados dezenove trabalhos que apontaram indicadores e aspectos relevantes para a avaliação da qualidade da educação especial e inclusiva. Os indicadores foram agrupados pelas suas características comuns, lições em seis componentes seleccionados: política; formação e treinamento profissional; o papel dos professores no ensino inclusivo; escolas, currículo e cultura escolar inclusiva; sistema educacional; e aluno. Esses componentes devem ser considerados na avaliação da educação especial, de que o atendimento seja pensado como uma oferta válida e verdadeira para pessoas com deficiência.
Effects of high temperatures and unloading confining pressures on granite

The mechanical and permeability properties of rocks under unloading stress path and high temperature are critically important for hot dry rock. A series of unloading confining pressure and gas permeability tests were conducted on granite samples after heating and rapid cooling treatment. Five levels of temperature and three levels of confining pressures were used. The stress–strain curves of unloading confining pressure were obtained. The strength parameters and deformation parameters were further discussed and analysed. When the heat treatment temperature is higher than 600°C, the granite samples experience a significant degree of thermal damage. With the increase in heat treatment temperature and the decrease in confining pressure, the gas permeability increases. Beyond 600°C, the gas permeability of the samples increases significantly. With the increase in temperature, the internal friction angle decreases slightly from 25 to 400°C, while it increases beyond 400°C. The cohesion exhibits an inverse evolution. The initial unloading elastic modulus and deformation modulus decrease gradually during relief of confining pressure. The decrease rate of the deformation modulus increases with the increase in heating temperature. The experimental results could improve knowledge about the effect of thermal shock and stress on the physico-mechanical properties of granite.

Published: September 2021

Data on the demand for medical care is usually measured by a number of different counts. These count data are most often correlated and subject to high proportions of zeros. However, excess zeros and the dependence between these data can jointly affect several utilization measures.In this paper, the zero-inflated bivariate Poisson regression model (ZIBP) was used to analyze health-care utilization data. First, the asymptotic properties of the maximum likelihood estimator (MLE) of this model were investigated theoretically.Then, a simulation study is conducted to evaluate the behaviour of the estimator in finite samples. Finally, an application of the ZIBP model to health care demand data is provided by way of illustration.

Tithonia diversifolia is a shrub with excellent forage characteristics that has shown a wide genetic and phenotypic diversity. The objective of this study was to determine the biomass production and nutritional quality of seven genotypes of T. diversifolia with outstanding characteristics for ruminant nutrition, to analyze the Genotype x Environment (GxE) interaction of biomass production and to compare the performance of these genotypes with grasses offered normally in tropical conditions. For the GxE interaction the AMMI and SREG models were used, and evaluations were made in three environments. In the GxE analysis, the interaction was significant and effects of the environment on biomass productivity were observed with differences between genotypes (p <0.05). In the three environments, the chemical composition was adequate to be offered to ruminants. It is worth noting the high content of crude protein (28.89 g/100 g of dry matter - DM), the low fiber content (30.95 g of neutral detergent fiber - NDF/100 g of DM) and the high percentages of in vitrodegradation of DM for all the genotypes. It is possible to conclude that there are superior genotypes of T. diversifolia with the ability to have good productive and adaptive performance for high-altitude and low-altitude zones with low fertility soils.

Organic fertilizer in many cases can replace mineral fertilizers and in consequence reduce production costs and improve soil quality. Thus, the aim of this work was to evaluate productive, morphogenic and structural characteristics of Piatã grass (Urochloa brizantha) fertilized with urea, organic compost and biofertilizer throughout a year. The trial design was a block split-plot in time (seasons) design with 4 treatments (fertilizing with urea, organic compost, biofertilizer and Control) and 6 repetitions. The evaluated parameters were: dry matter production (DMP), leaf elongation rate (LER), leaf appearance rate (LAR), phyllochron (PHYL), leaf lifespan (LLS), pseudostem elongation rate (SER), final leaf length (FLL), number of live leaves (NLL) and number of tillers (NT). The highest LAR values were observed during summer and spring for the treatment with urea, which also produced the highest LER values. No difference was found in SER among the fertilizer treatments but all fertilized treatments were superior to Control. NT and DMP values were highest (P<0.05) in the treatment with urea, followed by biofertilizer, organic compost and Control. In conclusion, while the use of urea provided greatest forage production, applying biofertilizer gave superior yields to organic compost. Other benefits of organic fertilizers should be assessed as well as combinations of organic and inorganic fertilizers.

Objetivo: Deconstruir la categoría de mujeres víctimas del desplazamiento en Colombia. Metodología: Se realizó un análisis del contenido de los testimonios de las mujeres víctimas del desplazamiento que participaron de la investigación traduciendo los testimonios de las mujeres víctimas del desplazamiento en Colombia. Resultados: Los resultados localizaron en los testimonios elementos y hechos del cotidiano de las mujeres víctimas, referentes a los procesos de militancia política en las organizaciones de base y en el movimiento de víctimas a nivel nacional, analizándolos desde la perspectiva de género de los estudios feministas poscoloniales y decoloniales. Conclusión: La categoría de mujeres víctimas se articula desde la lógica de los procesos de militancia política, la cual está atravesada por la lógica de la sociedad patriarcal que las victimiza de varias maneras, y en contraposición generan estrategias de reexistencia, resignificando su condición de mujeres víctimas.
Violencia armada y género: análisis de la relación a partir de los relatos de vida de jóvenes mujeres de la ciudad de Cúcuta y su área metropolitana
Authors: Niño Vega Nohora Constanza
Published: September 2021

Objetivo: Se pretende reflexionar acerca de la relación de violencia armada y género a partir del análisis de los relatos de vida de jóvenes de la ciudad fronteriza de Cúcuta (Colombia). Metodología: Se realizaron entrevistas a profundidad con jóvenes habitantes de tres sectores marginales de la ciudad de Cúcuta y de su área metropolitana y tres relatos construidos con jóvenes mujeres infractoras de la ley. Resultados: Se plantea que la dinámica de la violencia armada que desarrolla el crimen organizado y la delincuencia común ha estado en transformación de su lógica armada y aunque existe involucramiento de jóvenes mujeres dentro de sus filas, aún se les incluye de manera diferencial en razón de su género. Conclusión: Las mujeres suelen compartir su rol como parejas, pues juegan un papel importante en la noción de mujer trofeo; asimismo, desarrollan el papel de pacificadores capaces y como objetos sexuales.
