Authors: Basha A.M. Ilias , S. Chandan , Gajendra Gajendra
Published: January 2022

BACKGROUND The incidence of forearm fractures is increasing faster than the usual predicted rate due to rapid industrialization, increased incidence of motor vehicle accident and various sports activities and increase in the incidence of fall and direct blow. For pronation and supination to occur, the maintenance of interosseous space becomes mandatory while fixing the fractures involving radius and ulna.1 Both bone forearm fractures are not uncommon. Healing occurs reliably after closed treatment but malunion with resultant decreased rotation of the forearm is common and has been associated with poor results.2,3 The purpose of this study was to analyse functional outcome of both bone forearm fracture in patients above 12 years of age treated with dynamic compression plating and intramedullary nailing. METHODS This is a prospective comparative study of 30 cases of diaphyseal fracture of both bones of forearm who attended casualty and out-patient department (OPD) of Government General Hospital, Kurnool and were treated by surgical fixation with dynamic compression plating and intramedullary nailing between November 2018 to November 2020. RESULTS The functional outcome as per modified grace eversmann scoring system in dynamic compression plating (DCP) group was that 80 % (12 patients) had excellent results, 20 % (3 patients) had good results with no patient having fair and poor results. In the intramedullary nailing (IMN) group, 66.7 % (10 patients) had excellent results, 13.3 % (2 patients) had good results, 13.3 % (2 patients) had fair results and 6.7 % (1 patient) had poor result. CONCLUSIONS Even though plate osteosynthesis is still the most commonly used form of fixation in both bone forearm fractures, titanium elastic nail and intramedullary nail fixation are relatively newer techniques which offer viable and more efficient alternative especially in fixation of fractures involving shafts of radius and ulna.

BACKGROUND Preclinical studies have shown a neuroprotective effect of albumin in acute ischemic stroke (AIS). Owing to the scarcity of clinical studies establishing the correlation of serum albumin levels and AIS, the present study was conducted using National institute of health stroke scale score (NIHSS). METHODS The present prospective observational study evaluated the association of serum albumin and NIHSS score at baseline, 1 week, 1 month and 3 months of admission in 18 participants aged 18 years or more admitted within 48 hours of AIS in Internal Medicine Department of Government Medical College, Trivandrum between 2019 and 2020. Participants with transient ischemic attack, atrial fibrillation, decompensated cirrhosis of liver, nephrotic syndrome, hypoalbuminemia, hypercholesterolemia, and intracranial hematoma were excluded. Institutional Ethics Committee approved the project and written informed consent was obtained from all study participants. Serum albumin was estimated using enzyme linked immunosorbent assay (ELISA) kit using standardized technique. Logistic regression was used to determine the association of albumin and NIHSS. Analysis was done using R and p < 0.05 was considered statistically significant. RESULTS The mean age of study participants was 60.2 (12.9) and 55.6 % participants were males. 11.1 %, 5.6 % and 22.2 % participants had history of ischemic stroke, chronic kidney disease, and coronary artery disease respectively. At baseline serum albumin was 3.5 (1) g/dL and NIHSS was 13.2 (9.3). Negative correlation between serum albumin and NIHSS scale at baseline (r = -0.873, p < 0.01), at one week (r = - 0.856 and p < 0.01), at one month (r = -0.856 and p < 0.01) and three months (r = - 0.856 and p < 0.01) was observed. CONCLUSIONS Lower serum albumin level was associated with severe neurological deficit and had worse outcomes in patients with acute ischemic stroke. Albumin can be used as an easy, inexpensive, rapid, and reliable tool in determining the prognosis of AIS. KEY WORDS Serum Albumin, Acute Ischemic Stroke, Outcome, Prognosis, NIHSS

BACKGROUND Lack of an approved treatment or vaccine for COVID 19 especially in the initial phase of the pandemic has resulted in emphasizing effective preventive measures to avoid a disaster. From the very beginning, several international and national guidelines were issued on the preventive measures to be taken by the public as well as health care workers (HCWs) to protect themselves from COVID 19 infection. Kerala government launched the “Break the chain” campaign in the fight against COVID 19. The present study was to assess the adherence to COVID 19 protocols among health care workers and patients in a tertiary care hospital in central Kerala. METHODS An audit was conducted by the hospital infection team using checklists prepared specialty wise to assess the adherence to the COVID 19 prevention policies of the hospital for a period of 2 weeks from 20th June to 4th July 2020. The results were analysed and expressed in percentages. RESULTS Compliance to the instruction to wear minimum of surgical mask was very good among different categories of hospital staff (90 – 98 %) but less among patients and by standers (69 - 88 %). Social distancing was better in out-patient departments (OPDs) (88 %) but hand hygiene compliance was better in wards and intensive care units (ICUs) than OPDs. CONCLUSIONS Adherence to COVID 19 protocols was good in our centre in the initial months of the COVID 19 outbreak in our areas. Continuous reinforcement of these preventive measures to all categories of hospital staff and public plays a very important role in controlling this pandemic.

Persentase terbesar penyisihan logam Cu menggunakan karbon aktif mencapai 98,33% diperoleh pada pH 9, sedangkan persentase terbesar penyisihan logam Cu dengan adsorben zeolit sintetis mencapai 99,87% diperoleh pada pH 4. Persentase penyisihan logam Cd tertinggi dengan karbon aktif mencapai 98,60% dan dengan zeolit sintetik sebesar 97,20%, yang dicapai pada pH sama yaitu pada pH 8. Dapat disimpulkan bahwa nilai pH berpengaruh pada penurunan logam Pb dan Cu dengan metode adsorpsi menggunakan karbon aktif dan zeolit sintetik, sedangkan untuk logam Cd, pengaruh pH tidak signifikan.ABSTRACTLaboratory wastewater should not discharge directly into the environment without further processing. This can cause pollution to the environment whose impact is also felt by living things around it. The materials contained in laboratory wastewater are classified as hazardous and toxic waste (B3) containing organic and inorganic materials such as Cd, Pb, Cu, Hg, Cr, Zn, Fe, and other heavy metals. This study aims to reduce heavy metals in laboratory wastewater using the adsorption method of adsorbents. Therefore, this study focused on reducing the levels of heavy metals Pb, Cu, and Cd in laboratory wastewater using the activated carbon and synthetic zeolite as adsorbents. The largest percentage of Pb metal removal using activated carbon of 97.93% was achieved at pH 7, while by using synthetic zeolite was 98.47% achieved at pH 6. The largest percentage of Cu metal removal using activated carbon adsorbent of 98.33% was obtained at pH 9, while the largest percentage of Cu metal removal with synthetic zeolite of 99.87% was reached at pH 4. The highest percentage of Cd metal removal with activated carbon of 98.60 % and with synthetic zeolite of 97.20%, which were achieved at the same pH of 8. It can be concluded that the pH value influences the reduction of Pb and Cu metals by adsorption method using activated carbon and synthetic zeolite, as for Cd metal, the effect of pH is not significant.

This study aims to describe the relationship between website exposure variables and community participation variables in village development through the use of village information system communication technology (SIDA) through the provision of village websites so that various data and information related to village policies are quickly and routinely disseminated and easily accessible to residents. Through village websites in Nglanggeran and Girijati Village, Gunungkidul Regency. The research method used is the mix method sequential explanatory design with the method of distributing questionnaires, followed by in-depth interviews and observations. The data obtained were analyzed by non-parametric statistical quantitative analysis. The results of the statistical analysis are then taken to the field to be used as a basis for interviews and qualitative analysis to build theories or patterns of certain knowledge based on participatory perspectives. The findings are in the form of a description of the case and the alleged factors stated in the summary of findings and research on knowledge. The results showed that the existence of the website at the level of government administration was quite effective. However, in increasing community participation, the village website has not been able to create a cognitive, affective and conative impression on increasing awareness in development and community participation. This is due to several factors such as news of the value, consistency and variety of the SIDA program, internet connectivity and ownership of access devices, social capital, oral culture, and policies that are misleading to local governments. To maximize the existence of the website, the community needs to be given strengthening citizen journalism so that the community's active role is in the process of reporting, reporting, analyzing, and presenting better news and promoting communication between citizens and the village government.
Selective Interruption of Auditory Interhemispheric Cross Talk Impairs Discrimination Learning of Frequency-Modulated Tone Direction But Not Gap Detection and Discrimination

Published: January 2022

Functional hemispheric lateralization is a basic principle of brain organization. In the auditory domain, the right auditory cortex (AC) determines the pitch direction of continuous auditory stimuli whereas the left AC discriminates gaps in these stimuli. The involved functional interactions between the two sides, mediated by commissural connections, are poorly understood. Here, we selectively disrupted the interhemispheric cross talk from the left to the right primary AC and vice versa using chromophore-targeted laser-induced apoptosis of the respective projection neurons, which make up 6–17% of all AC neurons in Layers III, V, and VI. Following photolysis, male gerbils were trained in a first experimental set to discriminate between rising and falling frequency-modulated (FM) tone sweeps. The acquisition of the task was significantly delayed in lesioned animals of either lesion direction. However, the final discrimination performance and hit rate was lowest for animals with left-side lesioned commissural neurons, demonstrating that also information from the left AC is relevant for FM direction learning. Photolysis after successful learning did not affect the retrieval of the learned task, indicating that the disruption during learning was not because of a general functional impairment. In a second experimental set, the gerbil's ability to detect and discriminate small silent gaps of varying length within FM sweeps was tested. This ability was also preserved after interhemispheric disruption. Taken together, interhemispheric communication between the left and right AC is important for the acquisition of FM tone direction learning but not for its retrieval and for gap detection and gap duration discrimination.

SIGNIFICANCE STATEMENTHemispheric lateralization of neuronal functions such as speech and music processing in humans are common throughout the brain; however, the involved interhemispheric interactions are ill-defined. Here, we show that the selective photolytic disruption of auditory cortical commissural connections in rodents impairs the acquisition but not retrieval of a frequency-modulated tone direction discrimination task. The final discrimination performance and hit rate was lowest for animals with lesioned left-to-right-side projections; thus, although right auditory cortex is dominant, left auditory cortex is also relevant for learning this task. The detection and discrimination of small gaps within the tone sweeps remain intact, suggesting a pathway for the processing of these temporal structures, which could be independent from the lesioned interhemispheric cross talk.
Retirement Planning: Charles Warren Callister, the Neighborhood Unit, and the Architecture of Community at Rossmoor and Heritage Village
Authors: Lasner Matthew Gordon
Published: January 2022

In the early 1960s, amid affluence, loneliness, and increasing longevity, a new type of community appeared in the United States: the “active-retirement complex,” with thousands of houses and/or apartments and an unprecedented range of communal facilities. Though such communities were instantly popular, skeptics likened the first examples to internment camps, and to deflect such critiques, developers like Ross Cortese began to prioritize design. In Retirement Planning: Charles Warren Callister, the Neighborhood Unit, and the Architecture of Community at Rossmoor and Heritage Village, Matthew Gordon Lasner describes how Cortese hired acclaimed San Francisco Bay Area architect Charles Warren Callister, known for his innovative private and ecclesiastical commissions, to design a new retirement community known as Rossmoor, located in the East Bay suburb of Walnut Creek. Long interested in housing reform, Callister attempted to serve the needs of seniors, especially their needs for community and activity, by employing a village plan and arranging the housing in “neighborhoods” around clustered courtyards, both at Rossmoor and at a later project, Heritage Village in Connecticut. Lasner’s study examines the experiences of residents of Callister’s complexes to determine whether this approach, which was rooted in theory rather than gerontological research, “worked” as intended.

Published: January 2022

Aim — The present study was aimed to measure some hemato-biochemical parameters of male Sprague-Dawley rats co-exposed to different levels of heat stress and Trichloroethylene (TCE) exposure. Methods — All male rats were randomly divided into nine equal groups of 5 animals each. They were exposed to heat stress and TCE vapors in a subacute manner (8 hr/day for 10 days) according to experimental design. Blood samples were taken from the heart of all animals at the end of the 10th day of exposure. Hematology and biochemical parameters were determined using the automated hematology analyzer and an automated biochemistry, respectively. Results — The values of WBC, RBC and HB significantly decreased after co-exposure 250 ppm TCE and extreme heat stress; although, this exposure condition lead to statistically significant increase in mean levels of MCV, RDW, ALP, CPK and LDH. Our findings indicated that there were the subtractive and independent interactions for the hematological parameters and the additive, subtractive and independent interactions for biochemical parameters based on the exposure level to trichloroethylene and heat stress. Conclusion — Heat stress may increase sensitivity of workers to trichloroethylene and the simultaneous effects of exposure provide the circumstances for the occurrence of a variety of disorders.

Published: January 2022

Background — The study of physiological mechanisms of human acclimatization to extreme climatic conditions is an urgent task in current socioeconomic conditions of the Arctic region development. Natural cycles of seasonal adaptation based on light stimulus cause functional restructuring of the cerebral cortex and subcortical activity centers and change the activity of the autonomic nervous system. Objective — The article aims at determining the characteristics of brain energy metabolism in Arctic region residents with different autonomic tones during different seasons. Material and Methods — The first stage of our study was conducted using the computer appliance VNS-Spectrum (Neurosoft LLC, Russia) and resulted in setting up two groups: with predominance of the parasympathetic autonomic nervous system (26 subjects) and with prevailing sympathetic autonomic nervous system (23 individuals). At the second stage, the study of the seasonal dynamics in cerebral energy processes took place (in October, December, March, and June) by means of using the five-channel diagnostic complex Neuro-KM for topographic mapping of brain electrical activity via direct current potential levels (DCPL). Results — Our results did not exhibit statistically significant gender-related differences, hence they permitted to form a single group. The results were compared with the software reference values for the norm. Conclusion — Enlarged levels of natural light prompt the activation of energy metabolism in frontal and occipital lobes of the Arctic residents’ cortex, accompanied by forming an exhaustion area in the temporal lobes. In the group of sympathotonic individuals, we revealed somewhat tense adaptation processes. Adaptation process of brain energy supply in vagotonic individuals occur less stressfully during the annual cycle.

The objective of our study was to reveal the morphofunctional interactions between allografts and the recipient nervous system from the experimental model of the mimetic musculature reinnervation.
Materials and Methods. The experiments were conducted on Chinchilla rabbits (n=36). All animals were subjected to the facial nerve transection. No other manipulations were performed in the Control Group (n=9). In Treatment Group 1 (n=12), an autograft fragment of the masseter muscle with a neurovascular bundle was attached to the denervated buccinator. In Treatment Group 2 (n=15), allogeneic biomaterials – specifically, Regeneration Stimulator and Vasculogenesis Stimulator, were inserted between specified muscles. The animals were removed from the experiment on days 10, 30, 60 and 180. Tissue pieces from the operation zone were analyzed using transmission electron microscopy.
Results. It was established that compensatory and restorative processes in the Control Group and Treatment Group 1 end with scarring of the boundary zone and contracture of mimetic muscles. In Treatment Group 2, we observed revascularization of mimetic musculature, as well as axonal ingrowth into the buccinator and restoration of neuromuscular synapses.
Conclusion. Allogeneic biomaterial transplantation creates adequate conditions for the restoration of the organ vascular bed and the innervation apparatus of denervated mimetic muscles. The results of our experiments could be regarded as an example of restoring the interlevel relations in the human body following the use of allogeneic biomaterials.

Published: January 2022

Bamboo can be used in a variety of ways, including as fuel and as household and construction materials. Due to its versatility, the material is of high economic value. This study investigated the fuel properties of six bamboo species grown in Indonesia. Each bamboo sample was carbonized at different temperatures. Proximate and ultimate analyses were carried out on the bamboo samples. The thermal maturity of the bamboo samples as a solid fuel was investigated by the van Krevelen diagram. The efficiency of bamboo at each carbonizing temperature was determined based on the char yield, energy densification rate, energy efficiency, and calorific value. The results showed that the ash and fixed carbon contents of carbonized bamboo increased with an increasing carbonization temperature; while the volatile matter decreased. Significant changes in the fuel properties were observed between 200 °C and 400 °C. Carbonized bamboos showed lower sulfur contents in comparison to other fossil fuels. Ampel bamboo showed a calorific value of 18 MJ/kg to 32 MJ/kg, which was the highest value among the samples. Bamboo carbonized at temperatures above 600 °C showed a thermal maturity of coal grade. The results of this study can be used for utilizing Indonesian bamboo as a fuel source.

A “sociedade do desempenho” na perspectiva de Byung-Chul Han
Authors: Almeida Allyson Pereira de
Published: January 2022

O presente artigo tem por objetivo apresentar a noção de “sociedade do desempenho” e as suas principais características na visão do pensamento do filósofo sul-coreano Byung-Chul Han. Tendo por base o seu excesso de positividade, a “sociedade da transparência” acarreta inúmeros problemas destacados pelo autor. Aqui, trabalharemos com dois deles: o problema do excesso de positividade e o problema da pornografização. A partir deles, buscaremos também apresentar as soluções que lhes são propostas na perspectiva utilizada pelo autor. Tendo em vista o caráter coercitivo dos conceitos de “liberdade” e “autonomia”, apresentados por Han, procuraremos traçar um paralelo, a partir do seu aspecto dialógico, com o filósofo alemão Immanuel Kant a fim de podermos compreender melhor a sociedade atual na qual vive o indivíduo moderno, tendo por base as consequências oriundas do sistema capitalista neoliberal.

Sobre a natureza da ignorância
Authors: Bispo Lucas Jairo Cervantes
Published: January 2022

O presente artigo apresenta uma introdução ao debate entre duas alternativas relevantes que disputam a definição da ignorância proposicional, quais sejam, a Concepção Padrão e a Concepção Nova. Para a primeira, ignorância é ausência de conhecimento; para a segunda, ausência de crença verdadeira. Considerando essa divergência, cada uma dessas alternativas será exposta tendo em vista como definem a ignorância, os possíveis tipos de ignorância e as condições específicas para a ignorância proposicional. Além disso, suas vantagens e desvantagens referentes à ignorância proposicional serão brevemente contrapostas a partir dos seguintes pontos: usos na linguagem natural, unificação teórica, capacidade de lidar com casos de crença verdadeira ou crença verdadeira justificada que não são conhecimento e, por fim, relações entre ignorância e culpa. Com isso, esse artigo visa contribuir com a difusão em língua portuguesa de uma discussão recente, mas em crescimento na epistemologia analítica contemporânea.

Published: January 2022

Introduction. Legume nodulation is regulated by the exchange of molecular signals between the plant and rhizobia. The bacterial nodulation genes are activated by flavonoids present in root exudates. As a result of this activation, the Nod factors are synthesized, which in turn participate in the morphogenesis and function of the nodules. It is then possible to regulate the induction of Nod factors and other signals related to the nodulation process, during the inoculants production. Objective. To determine if the moment to induce the nodulation genes in Bradyrhizobium inoculants affects the synthesis of compounds related to the nodulation process and its interaction with soybean plants. Materials and methods. The research was developed in Rizobacter S.A., Argentina and Fyteko S.A. laboratories, Belgium, and in a plant growth chamber of the first one, during May-June of 2017. Two Bradyrhizobium strains were induced with daidzein in three moments. The signals produced by the strains and the biological effect in soybean plants were studied. Results. Differences were detected in the molecules produced by the bacteria, but it did not affect the growing and plants nodulation related to the different moments of induction. Conclusion. The metabolites excreted by Bradyrhizobium changed with strain and induction moment, although the latter did not affect nodulation or soybean plants growth.

El estudio de la morfometría espermática del venado cola blanca (Odocoileus virginianus peruvianus) permite caracterizar las células espermáticas de esta especie con propósitos de conservación. Objetivo. Determinar las subpoblaciones espermáticas según la morfometría de los espermatozoides epididimarios del venado de cola blanca, con un sistema CASA-Morph. Materiales y métodos. El estudio se desarrolló en el segundo semestre 2016, en la Universidad Nacional de San Antonio Abad del Cusco, Perú. En muestras de semen obtenidas del extremo caudal del epidídimo de dos venados (dos y cuatro dientes), se determinó con base en el sistema CASA-Morph, Integrated Semen Analysis System (ISAS®v1): la longitud, anchura, área, perímetro, elipticidad, elongación, regularidad y rugosidad de la cabeza del espermatozoide, también, la anchura, área, distancia y ángulo de inserción de la pieza intermedia. Se realizó un análisis de componentes principales (PCA) y se aplicó el modelo no jerárquico k-medias para determinar el número óptimo de clústeres. Resultados. Las variables morfométricas se distribuyeron en cinco PCA: elipticidad, tamaño, circularidad, ángulo de inserción de la pieza intermedia y anchura de la pieza intermedia, que explicaron un 81,24 % de la varianza total. El análisis de clústeres determinó cuatro subpoblaciones (SP), la SP1 agrupó células grandes, alargadas con alta elongación y elipticidad (21,76 %), la SP2 compuesta por espermatozoides de tamaño pequeño y delgados tanto en la cabeza como en la pieza intermedia (37,7 %), la SP3 se relacionó con la presencia de células alargadas con valores altos de anchura de la pieza intermedia, elipticidad y elongación (17,7 %), y la SP4 agrupó espermatozoides de tamaño intermedio de la cabeza y de la pieza intermedia (22,84 %). Conclusiones. La determinación de cuatro subpoblaciones espermáticas en el semen de venado cola blanca puede ser la base de programas de reproducción asistida de esta especie.

In this paper we investigate local foodways and ritual consumption in Iron Age Sicily through a study of cooking pots, integrating contextual, archaeozoological, archaeobotanical and chemical data. We focus on material from the central cult site of the settlement of Monte Iato, located in the hinterland of western Sicily, in order to explore the interaction between food, people, bio-/artefacts and environments as a process of formulating and reformulating social relationships and local power dynamics within specific social spaces and settings. We reveal different foodways and consumption practices within the same cult site, characterized on the one hand by long-standing traditions, with more or less constant and unchanging dishes, and on the other by the integration of external stimuli. We discuss the emergence of foreign- (Greek/Phoenician-) style cooking pots and ingredients as markers of an haute cuisine, developed with the aim of social differentiation.
Mapping the center of government in Latin America and the Caribbean: a typology
Authors: Guedes-Neto João V.
Published: January 2022

Abstract Over two decades ago, Bardach (1998, p. 4) highlighted a core problem of public administration: “Agencies cooperate? Of course not!” One of the solutions identified by scholars and practitioners has been the center of government (CoG), that is, organizations created by elected officials to facilitate inter-ministerial cooperation for the design and implementation of priority policies. Originally developed in European parliamentary systems or at Franklin Roosevelt’s presidential center in the United States, the CoG has recently gained momentum in Latin America and the Caribbean (LAC) after a collective effort between the IDB and the OECD. This paper maps the historical path and most recent institutional design of CoG organizations in 27 LAC countries as of 2020. The outcome of an exhaustive data collection process is a typology with five dimensions and 15 ideal types that help scholars and practitioners to better understand how and why these organizations have now been widely adopted in the region.
Uniformity and comparability: an analysis of the relevance for the Brazilian capital market
Authors: Guimarães Emanuelle Frasson , Rover Suliani
Published: January 2022

ABSTRACT This research aimed to analyze the relationship between the characteristics of uniformity and comparability and the fundamental qualitative characteristic of relevance of financial reports for the Brazilian capital market, discussing the possibility of a trade-off between comparability and relevance, the importance of considering both comparability and relevance to maximize the utility of financial statements, and the gaps regarding the “effectiveness” of uniformity and achieving comparability to the detriment of relevance. It is important to investigate the “effectiveness” of uniformity in terms of the utility of the decision due to the confusion that exists between the concepts of uniformity and comparability. The results will encourage regulatory bodies to reflect on the confusion that exists between uniformity and comparability and on fulfilling the characteristics of relevance and comparability, indicating what the relationship is between these from the viewpoint of the capital market. Uniformity is identified by means of the earnings covariance measure and comparability via the accounting function similarity measure. The relevance models are assessed using panel data regressions covering the period from 2013 to 2018. The sample includes companies from the B3S.A. - Brasil, Bolsa, Balcão belonging to sectors classified in the Level 2 North American Classification System (NAICS) that comprise at least two companies. The results indicated that uniformity is not relevant for the Brazilian capital market, even when it contributes to comparability. These can be explained by the possible production of superficial comparability. They also revealed that comparability is relevant and positively related to the share price. However, the inclusion of this variable led to a decrease in explanatory power, which may indicate the achievement of comparability to the detriment of relevance. Finally, it is revealed that the Brazilian capital market distinguishes between the concepts of uniformity and comparability when evaluating companies.
Earnings Persistence and Market Reaction to Earnings in the International Insurance Industry
Authors: Pimentel Renê Coppe
Published: January 2022

ABSTRACT Objective: this paper analyses the earnings persistence and market reaction to earnings in the international insurance industry. Methods: the analysis considers a sample of 307 listed international insurance companies from 2004 to 2019 and assesses several quantitative empirical models and estimations, including panel fixed effects and pooled OLS. Results: results indicate that operating cash flows are highly and strongly persistent when compared to the accruals component of earnings and that reported earnings are informative about companies’ performance. However, these findings vary significantly across insurance sub-segments. Additionally, the association between earnings and returns is significantly affected by specific companies’ performances in the sense that market agents review their expectation in a higher level when a reduction in earnings (bad news) is reported. Results also show that market risk patterns are positively associated with earnings response coefficient, suggesting a numerator effect of risk. Conclusions: overall, this paper provides evidence that economic analysis and scrutiny of earnings persistence and the market reaction to earnings announcements in insurance industry, and its insurance sub-segments, can provide superior assessment of future outcomes by investors, regulators, and academics.

Antecedentes: Los factores físicos y biológicos involucrados en la supervivencia y riesgos de mortalidad de plántulas, son importantes para comprender los procesos naturales asociados con su establecimiento en un contexto espacio-temporal.
Objetivos: Identificar qué factores ambientales definen el nicho de regeneración de Abies religiosa con base en la supervivencia y riesgos de mortalidad de sus plántulas.
Métodos: Se establecieron 17 parcelas de 1 m2 y en ellas, todas las plántulas de la cohorte 2019 fueron localizadas, numeradas y medidas en altura, número de hojas embrionarias, número de nudos y daños visibles y seguidas durante un año. Se determinaron las propiedades del suelo circundante a las parcelas. En cada parcela, se tomaron fotografías hemisféricas y con base en ellas, el dosel se estratificó en dos categorías: parcialmente cerrado y abierto. Los análisis se realizaron con los procedimientos LIFETEST y LIFEREG de SAS.
Resultados: Las curvas de supervivencia de las plántulas fueron distintas entre las categorías de dosel (Log-Rank: χ2 = 8.35, gl = 1, P < 0.05). La probabilidad de supervivencia bajo dosel abierto fue mayor (0.29 ± 0.01) que bajo dosel parcialmente cerrado (0.20 ± 0.01). Las variables con efectos positivos en los tiempos de supervivencia fueron: altura y número de nudos; proporción de luz directa, densidad aparente del suelo, temperatura media, humedad media y su coeficiente de variación, y la variación de la saturación de humedad del suelo.
Conclusiones: Estas covariables definen el nicho de regeneración de A. religiosa .

STUDY ON CRITICALITY AND NEUTRONIC SAFETY PARAMETERS OF NUSCALE FUEL ASSEMBLY. NuScale, a typical Pressurized Water Reactor (PWR) Small Modular Reactors (SMRs), offers a new opportunity for the future of nuclear industry. With 160 MW thermal power, NuScale has several advantages such as flexibility due to its modularity in construction. This work is focused on the study of criticality and neutronic safety parameters of NuScale fuel assembly using MCNP6 code and ENDF/B-VII library. The calculation results shows that criticality of fuel assembly type D is the highest among other assembly types because it has a fuel pin with pure UO2 without Gd2O3 concentration. The Doppler temperature coefficient (DTC) of fuel assembly type C is the most negative among other assemblies due to Doppler broadening effect on resonance region of capture cross section of 238U which is the highest concentration. The moderator temperature coefficient (MTC) of fuel assembly type D is the most negative among the other assembly types. The effective delayed neutron fraction (βeff) does not reflect a consistent trend among fuel assembly types. Fuel assembly type D shows the highest prompt neutron lifetime (ℓ) while the highest neutron generation time (Ʌ) is shown in assembly type C. It can be concluded that this study provides adequate results that can be used as a first step to carry out the neutronic computation and analysis of the NuScale full core.Keywords: Criticality, safety parameters, NuScale fuel assembly, MCNP6, ENDF/B-VII.
