The Phototextual Emergence of Hysteria: From the Iconographie Photographique de la Salpêtrière to J. M. Coetzee's Slow Man
Authors: Gilburt Iona
Published: March 2021

This article seeks to examine the emergence of the image of hysteria that originated at the Salpêtrière Hospital in Paris in the late nineteenth century and has since been transferred across new generations of phototexts through ekphrasis. It is first shown how this stereotypically feminine and sexualised image was initiated by the medical tome Iconographie Photographique de la Salpêtrière - an effect that belies the physicians' original intentions - and is then taken up in the public imagination by the surrealists André Breton and Louis Aragon before emerging in Georges Didi-Huberman's 1982 critical text Invention of Hysteria. Didi-Huberman's monograph offers insight into how persistent this image becomes, even taking shape in discourses that attempt to undermine it. Didi-Huberman furthermore highlights how developments in photographic technology have contributed to the shaping of hysteria. Finally, this article considers how the figure of the hysteric appears in J. M. Coetzee's 2005 novel Slow Man in the character of Marianna. The manner in which she is depicted presents an ekphrasis that can be matched to the vision of hysteria that began with the Iconographie Photographique de la Salpêtrière, thereby showing how this histrionic and gender-stereotyped iteration of hysteria from the nineteenth century remains a readily accessible mode of expression.

Can you describe your research area and where Brisbane sits in relation to your native title research? My main research area is the region surrounding Brisbane, the capital city of the State of Queensland. I particularly concentrate on the region within about 100 kilometres of the city, but at times I document individuals that may have come from 200 or 300 kilometres away, if these people had some sort of connection to Aboriginal families that lived closer to Brisbane
The Decolonising Camera: Street Photography and the Bandung Myth
Authors: Lee Christopher J.
Published: March 2021

This article examines the visual archive of the 1955 Asian-African Conference held in Bandung, Indonesia. Better known as the Bandung Conference or simply Bandung, this diplomatic meeting hosted 29 delegations from countries in Africa and Asia to address questions of sovereignty and development facing the emergent postcolonial world. A number of well-known leaders attended, including Jawaharlal Nehru of India, Zhou Enlai of China, Gamal Abdel Nasser of Egypt, and Sukarno of the host country, Indonesia. Given its importance, the meeting was documented extensively by photojournalists. The argument of this article is that the visual archive that resulted has contributed to the enduring symbolism and mythology of Bandung as a moment of Third World solidarity. More specifically, the street photography style of many images - with leaders walking down the streets of Bandung surrounded by adoring crowds - depicted an informality and intimacy that conveyed an accessible, anti-hierarchical view of the leaders who were present. These qualities of conviviality and optimism can also be seen in images of conference dinners, airport arrivals, delegate speeches, and working groups. Drawing upon the critical work of scholars of southern Africa and Southeast Asia, this article summarily positions the concept of the 'decolonising camera' to describe both the act of documenting political decolonisation as well as the ways in which visual archives produced during decolonisation can contribute to new iconographies of the political, which are both factual and mythic at once.
A descriptive study of United States bleeding disorders camps
Authors: Santaella Maria E. , Nichols Cynthia , Witkop Michelle
Published: March 2021

Background

Disease-specific camps present one means of helping children overcome the challenges associated with chronic conditions and improving clinical and psychosocial outcomes. For more than 50 years, bleeding disorders camps (BDCs) in the United States (US) have been promoting independence, self-care, and leadership skills in children with bleeding disorders, all while fostering camaraderie in a secure and safe environment. However, little is known about how BDCs are organised, administered, funded, staffed, or how staff are compensated.

Aim

This article aims to describe the attributes of BDCs that service the US bleeding disorders community, and to compare and contrast these attributes to identify gaps in the BDC system and areas for improvement.

Methods

The National Hemophilia Foundation (NHF), in collaboration with several members of its Nursing Working Group and Physical Therapy Working Group, developed a survey that was distributed to BDC administrators (CAs) and health care providers (HCPs).

Results

A total of 101 HCPs and 20 CAs completed the survey. Findings indicated that BDCs are an informal extension of both the HTCs and NHF chapters, reaffirming that camps play a crucial role in the overall care of bleeding disorders. In general, diminishing financial resources threaten the existence of BDCs. Although there are BDC guidelines for formal staff training and specific interventions delivered to camp participants, adherence is variable. Other gaps included minimal self-infusion education follow-up with no documentation on effect or benefit of infusion education provided at camp.

Conclusion

Addressing the gaps identified by this survey and documenting resultant data supporting the value of BDCs will facilitate their continued sustainability in light of increasingly limited funding.

Legal Measures of State Care for the Family in the Republic of Belarus in the Forms of Family Protection and Marriage Strengthening
Authors:   South Ural State University (National Research University), Chelyabinsk, Russia, Andryiashka M. V.
Published: March 2021

The article analyzes individual measures aimed at protecting and strengthening the institutions of marriage and family in the Republic of Belarus, in particular, the establishment of a differentiated rate of state duty charged for divorce in both judicial and administrative procedures, as well as the provision of basic and additional term for divorcing spouses to take reconciliation measures. The article is based both on the norms of international legal acts and their interpretation by the authorized bodies, as well as on the norms of the national legislation of the Republic of Belarus and current statistical data. The article draws a number of conclusions: on the non-uniform application of security terminology in relation to the institutions of marriage and family; on the irrational approach to setting the rates of state fees charged for divorce in an administrative procedure; on unnecessary administrative barriers in the form of a two-month term for registration of a divorce in administrative procedure.

Authors: Xu Peng , Servellita Venice , Langer Krzysztof , Weisgerber Dan , Murtaugh Gordon , R Abate Adam , Chiu Charles
Published: March 2021

We have developed a highly sensitive and specific LAMP(loop-mediated amplification)-based assay for the detection of SARS-CoV-2 that can potentially be used for at-home and point-of-care (POC) testing. The assay includes only three simple steps: (1) heat inactivate the sample mixed with lysis buffer and add LAMP reagent mix, (2) incubate the reaction on a heating device, and (3) read the result by inserting a lateral flow strip into the tube. Performance is comparable to gold-standard RT-PCR testing, as the assay is based on nucleic acid detection rather than antigen detection which is used by the majority of lateral flow strip-based assays. There is minimal pre-processing involved and no bulky instrumentation needed, and non-lab professionals can follow the instructions and understand the results easily. The assay targets the SARS-CoV-2 nucleoprotein (N) gene and is capable of detecting as low as 4.0 copies per reaction (0.5 copies/μL) of SARS-CoV-2 RNA, demonstrating no cross-reactivity with a panel of 20 other respiratory pathogens. Furthermore, the test can be run on multiple sample types, including nasopharyngeal and/or oropharyngeal swab and saliva samples. Overall, this assay provides a rapid (sample-to-answer turnaround time of ~40 min), accurate, and affordable solution to the challenge of at-home diagnostics for SARS-CoV-2.

Published: March 2021

Wastewater is the remainder of an activity released in the liquid form. Wastewater product is feared to have negative influence on the environmental balance; therefore, it is necessary to measure the quality standards of wastewater as a reference in the disposal and treatment. Bioremediation is an environmentally friendly technology utilizing microorganisms as agents in the process of cleaning or restoring wastewater conditions. The use of microorganism services can reduce the concentration of organic waste into simpler organic compounds by converting organic compounds into CO2, CH4, H2, and H2S, as well as water and energy intended for the process of growth and production of microorganisms in the remediation process. This study aims to identify the type of dominant bacteria growing in the wastewater of the sugar factory and has a potential role as a bioremediation agent for the waste. The method used in this study is the experimental, by observing several environmental parameters as indicators, among others, BOD, COD,TSS, and pH. The results of this study found two types of dominant bacteria, i.e., Staphylococcus aureus and Bacillus subtilis, then used as bioremediation agents. The bioremediation activity was able to reduce pH, BOD, and COD levels.

Published: March 2021

A chitinase-producing bacteria was locally isolated from rhinoceros beetle (Oryctes rhinoceros) larvae gut discovered in mushroom compost. A strain was selected from the source and labeled as RBLG1. It was identified using 16s rDNAsequencing and has strong homology to Bacillus cereus. Chitinase produced from RBLG1 was purified using ammonium sulfate precipitation, ion exchange chromatography, and gel filtration. The purified chitinase from RBLG1 shows the homogeneity 1.9 fold after the gel filtration process. The purified chitinase was identified and analyzed using SDS-PAGE and the molecular mass from the strain was approximately 40 kDa. Further assays were performed to study the effect of temperature, pH, and metal ion on the purified enzyme. The purified enzyme shows highest chitinase activity at pH 4 and 60 °C. For metal ion test, chitinase from RBLG1 was unaffected when treated by various ions. Kinetic performance of chitinase using Michaelis-Menten equation shows Km and Vmax values were 2.3 mM and 0.0294 [P] mM/min, respectively.

Purpose of the study. Studying the dynamics of factors of apoptosis in mitochondria of skin and tumors cells in female mice with melanoma growth stimulated by chronic neurogenic pain. Material and methods. The study included female С57ВL/6 mice (n=56) with a model of chronic neurogenic pain (CNP) produced by the bilateral sciatic nerve ligation and with transplanted B16/F10 melanoma. After 1–3 weeks of the tumor growth, levels of cytochrome C, caspase‑9 (Bioscience, Austria), Bcl‑2 (Thermo Fisher Scientific, Austria), and AIF (RayBiotech, USA) were determined by ELISA, and levels of calcium (Са2+) were determined by the Arsenazo III method (Abris+, Russia) in mitochondria of tumors cells and skin not affected by the tumor growth. Results. In the CNP state, mitochondria of the skin cells showed a significant increase in Са2+ by 96.7 times, AIF by 1.4 times and Bcl‑2 by 5.9 times, while caspase‑9 decreased by 2.6 times, compared to the levels in intact mice. In the CNP‑stimulated melanoma growth, mitochondria of cells of the skin not affected by the tumor growth demonstrated a decrease in all studied indices, except caspase‑9 – its levels increased by 4.6 times after 3 weeks of the tumor growth. In mitochondria of the tumor cells within 1–3 weeks, levels of Са2+ decreased over time by 37.2–96.1 times, respectively, AIF by 49.4–2.0 times, Bcl‑2 by 3.0–1.5 times, cytochrome C by 15.3–8.8 times, and caspase‑9 increased by 1.7–4.4 times compared with the level in animals with pain. Conclusions. In general, the growth of melanoma stimulated by chronic pain and the standard melanoma growth were characterized by the opposite dynamics of levels of apoptosis factor both in mitochondria of skin cells and in mitochondria of tumor cells, with the exception of cytochrome C. Mitochondria of melanoma cells and of the unchanged skin have a similar tendency to change the levels of apoptosis factors, which may indicate their functioning in the conditions of the mitochondrial network at the level of one organ. Mitochondria of tumor cells provide the anti‑apoptotic state of the tumor itself and of the skin not affected by the malignant process, probably due to the stress state of the skin.

Published: March 2021

The analysis of the current evidence base concerning the use of oral nutritional supplements (ONS) in gastric cancer (GC) has been made. Databases of scientific information eLIBRARY.ru and PubMed were used. Emphasis is placed on randomized clinical trials and meta‑analyses. The application of ONS is suggested for all patients who undergo to surgical treatment for GC. Its use allows increasing protein and energy consumption, improving the quality of life, some parameters of nutritional status and immunity (albumin, blood lymphocytes etc.). In patients with severe malnutrition (SM) ONS can significantly reduce the incidence of clinically important postoperative complications. The use of this type of medical nutrition in the first 5 days after surgery is safe and does not increase the rate of anastomotic leak. After gastrectomy (GE) its administration reduces the time of recovery of bowel motor function and the duration of hospitalization. After distal GE delay of gastric emptying may occur. In patients with SM, early start of enteral nutrition should be considered. After discharge from the hospital ONS can decelerate the progression of malnutrition, improve the tolerance of adjuvant chemotherapy and improve the quality of life. These effects are most clear after GE and in patients with a high risk of malnutrition (NRS‑2002 ≥ 3). There are no evident advantages of any particular type of ONS in patients with GC. When choosing a specific product, preference should be given to formulas with optimal nitrogen: non‑protein kilocalories ratio, osmolarity closest to physiological and individually selected organoleptic properties. It is recommended that the patient consume at least 200–250 ml of the mixture per day, and in the early postoperative period focus have to be made not on the target volume, but on signs of tolerability.

Purpose of the study. To study the comparative state and variability of cognitive capabilities, the degree of their correlation with the subjective and objective state of health among students of a medical university. Materials and methods. The study was carried out during the year from 01.12.2018 to 01.12.2019 at the Far Eastern Federal University and the Pacific State Medical University. The sample size is 394 respondents. The response rate is 91.9%. The state of co‑cognitive functions was determined according to the Montreal scale for assessing cognitive functions (IOC‑test; MoCA, Montreal Cognitive Assessment). For the self‑assessment of the quality of life, the “Brief form of self‑assessment of the quality of life related to health MOS SF‑36” (MOS SF – Medical Outcomes Study‑Short Form) was used. To collect information on social, economic, physiological, behavioral status, a specialized questionnaire Pozdeeva (2008) and standard medical documentation were used. Results. The total indicator of the assessment of cognitive functions in students was 26.1 points, in senior students it was slightly higher (26.8/25.5, p≥0.05). It was found that in the learning process, students significantly increase the level of executive functions (3.1/3.8, p≤0.05), attention, concentration and working memory (4.2/4.8, p≤0.05). The final assessment of physical health among primary students was 69 points, for senior students – 72 points. The indicator of mental health among students of the initial period of study was estimated at 52 points, among graduates – at 62 points (p≤0.05). The composite indicator of the quality of life associated with health was equal to 60 points for 1–3 year students, 67 points for 4–6 year students, (p≤0.05). The students of both age cohorts had a high incidence of chronic somatic pathology, the comorbidity index was 0.6, however, the number of visits to the doctor among senior students was significantly lower, in junior years (3.2/2.1, p≤0.05). The total indicator of the students' cognitive function was most strongly associated with physical activity (r=0.85, p≤0.05) and the state of physical health (r=0.73, p≤0.05). Conclusions. Cognitive functions in medical students correspond to normal values. The activity of executive functions, attention, concentration and working memory significantly improves in the process of studying at a medical university. Medical students value their health‑related quality of life highly, but most of them have chronic medical conditions. Senior students assess their psychological status more highly by optimizing the emotional component. The total indicator of the cognitive function of students is interrelated with the frequency of physical activity, the state of physical health, quality of nutrition, self‑assessment of mental health and psychological comfort.

Building Information Modeling (BIM) is one of the most popular research topics not only in computer science but in multidisciplinary studies. In this study, an integration of wireless sensor networks (WSN) and BIM is established. The most crucial challenge in this integration is to manage the sensor data streams and manage such pervasive environment that includes heterogeneous wireless sensor devices. Since the environment (such as smart building or smart city) covers heterogeneous wireless sensor devices for various physical measures, each sensor has its own sensor data stream and data structure. Existing studies in this field bring many dependency and can be adapted to a single application. However, such systems should be more generic and address to multidisciplinary research areas. Here, a BIM based real time smart environment management system is proposed. 3D model of the building is achieved in early stages. A BIM based platform is established and it provides a common workspace for all partners of the studies.

Published: March 2021

Ultra-wideband (UWB) microstrip filter design has been proposed by applying defected ground conductor structures designed with the superformula approach. Simultaneously, the effects of the materials used in the designs on the filter properties have been examined. After the filter characteristics have been determined, the filter design has carried out in the AWR program. The filter structure has based on an 8 GHz center frequency fifth-order Chebyshev ultra-wide bandpass filter. The filter model designed in AWR has transferred to the HFSS program, and the effect of FR4 and RO3035 materials on filter characteristics have been investigated. The various number of defects, each shaped with superformula, is opened to the base conductor, and their effects are observed. The parameters in the superformula proposed by Johan Gielis have been calculated in the MATLAB program. PCB productions of the designed filters have been made, and experimental measurements have been taken with the Anritsu spectrum analyzer device. When the results obtained from electromagnetic simulation programs have compared with the experimental measurement results of the filters produced, it has been seen that the results are consistent with each other.

Published: March 2021

Introduction. When revealing a sacrococcygeal tumor in pediatric patient (especially newborn), a germ-cell tumor (GCT) (mostly teratoma) should be suspected. Just observation in cases of such tumors of small size, which might look as an option, cannot be recommended.

Aim of study: to reveal the peculiarities of diagnostics and treatment of small-sized sacrococcygeal GCT in newborns.

Materials and methods. We analyzed the data of charts of patients with sacrococcygeal GCT from 2 clinics of St. Petersburg (pediatric surgical hospital CCMCSCHMT and pediatric oncological department of St. Petersburg Oncocenter) for past 15 years (20052019). Among 55 newborn patients the size of tumor varied, comprising 14 giant (over 14 cm in diameter), 18 large (1014 сm in diameter), 21 medium-sized (39 cm), and 2 small-sized teratomas (under 3 cm in diameter).

Results. In both cases of small-sized GCT prenatal ultrasound was unable to reveal the tumor. Those patients appeared by surgeon occasionally (being either not transferred to hospital from the delivery house after birth or coming because of some other reason). Both patients underwent radical surgery with excision of coccyx (histological diagnosis being mature teratoma) and are still under observation of oncologist (with no signs of relapse during 6 months and 21 months). During the same period (20052019) there were 5 girls treated in St. Petersburg Oncocenter, with sacrococcygeal GCT first diagnosed at older age (10 months 2 years 9 months). They all had less favorite course and prognosis (histologic variants being yolk sac tumor or embryonic carcinoma; having remote metastases in 2 cases, with relapse in 1 case, and lethal outcomes in 2 cases).

Conclusion. Small-sized sacrococcygeal GCT in newborns can bear a significant risk of delayed diagnosis with possible further malignization and formation of metastases, so active revealing and active surgical treatment in such cases is needed.

Published: March 2021

Complying with certain requirements or, more precisely, following the guidelines for the design of a scientific publication helps to make it not only more comprehensible for reviewers and readers, but actually enhances the quality of work. For example, even if some aspects in design logic were fulfilled but not described, other researchers doing meta-analysis may wrongly but for a good reason downgrade such publication and exclude it from the analysis. understanding of the guidelines for study design ensures not only the proper description of the results but the initial planning of work. The CARE guidelines were established for reporting of clinical cases, STROBE for reporting observational studies (cohort and case-control studies), CONSORT for reporting randomized studies (these guidelines are often used also for other comparative and case series studies), STARD for reporting diagnostic studies, and PRISMa for reporting of systematic reviews and meta-analyses. The present paper describes the key aspects of those guidelines and provides templates for graphic display of study design in form of flow charts. evidently, we should not forget that each study is unique and there is always a place for a reasonable compromise between requirements and the real logic of the research in place.

Stereo Visual Odometry for Indoor Localization of Ship Model
Authors: Kučić Mario , Valčić Marko
Published: March 2021

Typically, ships are designed for open sea navigation and thus research of autonomous ships is mostly done for that particular area. This paper explores the possibility of using low-cost sensors for localization inside the small navigation area. The localization system is based on the technology used for developing autonomous cars. The main part of the system is visual odometry using stereo cameras fused with Inertial Measurement Unit (IMU) data coupled with Kalman and particle filters to get decimetre level accuracy inside a basin for different surface conditions. The visual odometry uses cropped frames for stereo cameras and Good features to track algorithm for extracting features to get depths for each feature that is used for estimation of ship model movement. Experimental results showed that the proposed system could localize itself within a decimetre accuracy implying that there is a real possibility for ships in using visual odometry for autonomous navigation on narrow waterways, which can have a significant impact on future transportation.

Authors:   Department of Ophthalmology, General Hospital of Ningxia Medical University, Yinchuan 750000, Ningxia Hui Autonomous Region, China, Zhang Kai-Yun
Published: March 2021

AIM: To investigate the effects of mitomycin C (MMC) on corneal endothelial cells at different exposure time during laser-assisted subepithelial keratomileusis (LASEK).
METHODS: Patients who received LASEK were included and divided into Group T1 (15s≤t≤45s) and T2 (5s<t≤70s) based on the exposure time of MMC with corneal stroma. Cell density (CD) of corneal endothelial cells in central and peripheral cornea, average cell area (ACA), area standard deviation (SD), coefficient of variation (CV) and percentage of hexagonal cells (HEX) before surgery and at 1wk, 1, 3 and 6mo after surgery were compared between and within the groups.
RESULTS: A total of 196 eyes of 98 patients were included with 98 eyes in Group T1 and 98 eyes in Group T2. With the exception of peripheral ACA, central CV and HEX in Group T1 and T2, which significantly changed at 1wk after the surgery (P<0.05), there was no significant difference in central and peripheral parameters within both groups or between the groups (P>0.05).
CONCLUSION: Although transient acute changes in central CV and HEX and peripheral ACA were observed, there is no significant effect on the long-term corneal health status when MMC is applied in a reasonable time range in LASEK surgery.

AIM: To Compare of intravitreal bevacizumab and intravitreal bevacizumab and triamcinolone acetonide in eyes with bilateral diabetic macular edema.
METHODS: In this retrospective comparative-randomized study, 42 eyes of 21 diabetic patients with bilateral macular edema were evaluated. In one eye intravitreal injection of 1.25 mg bevacizumab (IVB group) was performed and in the fellow eye intravitreal injection of combined 1.25 mg bevacizumab and 1 mg triamcinolone acetonide (IVTA-IVB group) was performed. Main outcomes were the central macular thickness (CMT) measured with optical coherence tomography (OCT), ETDRS visual acuity (VA) and intraocular pressure (IOP).
RESULTS: Mean follow-up time was 4.7±1.5mo. In the IVB and IVTA-IVB groups, mean CMT was 494.7±114.4 µm and 546.8±165.6 µm before injections; 430.4±133.2 µm and 363.7±105.3 µm at first month; 484.8±167.4 µm and 407.3±108.7 µm at 3rd month; 550.4±191.5 µm and 516.8±158 µm after 6mo respectively. Differences were significant at first and 3rd month (P?0.05). In the IVB and IVTA-IVB groups, mean ETDRS VA score was 57.1±13.5 and 48.9±13.9 before injections; 62.2±14 and 58.8±12.1 at first month; 59±13.7 and 59.3±13.6 at 3rd month; 55.6±14.9 and 55.5±8.7 after 6mo respectively. Differences were significant at first and 3rd and 6mo (P?0.05). There was no IOP difference. IVTA-IVB group gains best VA at 3rd month after the first injection and maintains it for 6mo whereas IVB group gains best VA at first month and can be able to maintain for 3mo.
CONCLUSION: Injection of 1 mg IVTA-IVB seems to be better than IVB alone in improving VA for 6mo without any steroid dependent complications.

Published: March 2021

The urban expansion and the growth of economic activities related to tourism added to the port and maritime ones, resulted in the occupation of the Serra do Mar, in the municipality of São Sebastião/SP, increasing environmental degradation. The objective of the study was to evaluate the arboreal patterns in a 0.111 ha fragment around a 4.8 ha clearing in an area of Atlantic Forest in the city of São Sebastião (SP), allowing the revegetation plan to include native species observed in the region. The phytosociological analyses used the Point-Centered Quarter Method (PCQM), using 50 sampling points (30 in close areas, 10 in the forest edge, and 10 near one of the areas drains), with a minimum distance of 20 meters between them. The main variables analyzed were commercial height, diameter to chest height, successional category, and dispersion syndrome. Also, the number of individuals of each species was observed, as well as their basal area (G), absolute and relative density (DA and DR) and dominance (DoA and DoR), relative frequency (FR), and importance value (VI). The results indicate a higher proportion of non-pioneer species, with Guapira oppositte (Vell.) presenting the highest value of importance and density, and the Schizolobium parahyba (Vell.) Blake with the highest basal area. The survey data indicate the richness of species in the study area, serving as a basis for strategies for management and conservation of the environment. Phytosociological studies, although scarce, are important to support the analysis of preservation and the use of nature.

In common bean, the occurrence of weeds can cause significant reductions in the final grain yield. This study aimed to evaluate the efficiency of different herbicide trials, applied individually or in a mixture, in the management of common bean weeds. A randomized complete block was used, arranged in subdivided plots. The main plots consisted of three types of beans (Carioca Pérola cultivar, Black cultivar IPR Tuiuiu and one Red Bean strain VR20) and the subplots of different control modes, in four replications: hand weeding, fomesafen (250 g per hectare of ingredient active (g ha-1 of a.i.)), fomesafen (375 g ha-1 of a.i.), imazamox + bentazon (0,23 + 0,6g ha-1 of a.i.), imazamox + bentazon + fomesafen (0.23 + 0.6 + 125 g ha-1 of a.i.) and imazamox + bentazon + fomesafen (0.23 + 0.6 + 83 g ha-1 of a.i.). The following traits were evaluated during three seasons: weeds present in the area, phytotoxicity symptoms, and common bean grain yield. The data were analyzed using a variance analysis (F test), the means obtained were grouped by the Scott Knott test at 5 % probability. Differences in grain yield performance were observed between cultivars and crops season due to herbicide application. The most efficacy treatment for weeds was imazamox + bentazon + fomesafen (230 + 600 + 125 g ha-1 of a.i.), resulting in improved control and greater efficiency in avoiding grain yield losses.

Lifestyle is a reflection of the culture and civilization of a society and adherence to moral and social values. The product of this adherence is a system based on those values which, if derived from religious faith, results in a faithful life. The aim of this study is to provide a model for this type of life, which has been done by using narrative data taken from "Muntakhab Mīzān al-Ḥikmah " and by "grounded theory" method. The research findings show that the central category of this model is the faithful lifestyle that ontology, theism believing in resurrection are its causal conditions that are formed in the context of religiosity, faith, piety and good governance. Interventional conditions include: moral, social, economic evils and family injuries. In order to achieve the dignity of this world and the hereafter, which is the output of this model, one must use belief, worship, moral, social, economic and health strategies.

THE FIGURE OF THE ANIMAL IN THE POLITICAL PHILOSOPHY OF MAX STIRNER
Authors: Zhaivoronok Daniil V.
Published: March 2021

The article off ers a new reading of the philosophy of Max Stirner, one of the leading theorists of 19th century anarchism. While most of the traditional interpretations of this thinker’s work focus on traditional for political philosophy issues – analysis of the state, social inequality, opportunities for resistance, the relationship between society and the individual – this article off ers a new perspective, weaving together post-humanistic intuitions of present day philosophy and analysis of the animal fi gure in the works of Stirner himself. As the article demonstrates, attention to the fi gure of the animal opens up new dimensions in Stirner’s work and makes his philosophy relevant to the current debate within contemporary philosophy. In particular, the analysis of the fi gure of the animal helps to clarify Stirner’s relationship to the philosophy of Hegel and Feuerbach and enables novel understanding of his theory of subjectivity and the concept of rebellion (Empörung).

Objetivo: La capacidad intelectual (CI) y las funciones ejecutivas (FE) influyen en el rendimiento académico, lo que a su vez se asocia con la deserción universitaria que es un fenómeno que afecta a la sociedad colombiana en general. El objetivo de este trabajo fue analizar los factores de la CI y de la FE que tienen que ver con el bajo rendimiento y con el alto rendimiento académico en una muestra de estudiantes universitarios. Metodología: Estudio observacional, transversal de dos grupos (bajo y alto rendimiento académico), de tipo analítico, prospectivo. Resultados: Todas las variables de CI y de FE mostraron diferencias significativas entre los grupos del estudio (p≤0.05), con mejor ejecución por parte de los estudiantes con alto rendimiento académico. Conclusiones: Se encontraron déficits ejecutivos y en el CI, así como en la mayoría de las dimensiones de FE en los estudiantes con bajo rendimiento, tales como menor rendimiento en la organización y categorización verbal, la memoria operativa verbal, la categorización visual y el control inhibitorio, sin que hubiera alteraciones en flexibilidad cognitiva. En el grupo de menor rendimiento también se observó mayor velocidad de la memoria operativa visual que podría entenderse como compensatoria.
