Plant derived substances and herbal medicines have recently attracted the great interest towards their versatile application, as medicinal plants used in traditional and modern medicine. The aim of the current study was to investigate the antioxidant activity of Ziziphus mauritiana leaves extract followed with the formulation of herbal creams based on ZM methanolic extract then evaluate the physical characteristic and stability of the creams. After the methanolic extract was obtained by using Soxhlet extraction, the extract was assessed for antioxidant activity by using stable 2,2- Diphenyl-1-picrylhydrazyl (DPPH) which showed the IC50 value of the ZM extract is 10.57 µg/ml, while IC50 value for ascorbic acid is 4.19 µg/ml. Four formulations of water in oil (w/o) emulsion based cream was formulated based on Ziziphus mauritiana leaves extract which are F1, F2, F3 and F4. Several physical properties were evaluated such as organoleptic, pH, viscosity, homogeneity, washability and emmolliency which proved that all formulations have good homogeneity, non greasy and under suitable pH and viscosity. Based on thermal stability test (45 °C ± 70 % RH, for 48 hours), it showed that F4 is not stable at high temperature compared to other formulations. Therefore, the present study indicated that the Ziziphus mauritiana leaves extract has great potential for personal care product development.

The following study is dedicated to the analysis of a collection of internet memes as media products of discursive and humorous practices. The intertextuality of a meme is required criteria that must be present in its discursive, epistemological and aesthetic value; if the meme does not have this quality, it essentially has no chance of being put into use, gaining the status of a precedential phenomenon, and integrating into the culture altogether. Internet practices of humorous discussion reflect the main characteristics of society’s valuative and emotional response to the formed global pandemic situation. The main linguistic and discursive features of this response are intertextuality, interdiscursivity, polycody, and the use of language/word play, among which the most frequently used in this internet collection turned out to be the strategic utilization of absurdity and reframing-based linguocognitive play. Comic effects are achieved in most cases due to knowledge of precedential phenomena, which is why many memes are difficult to decode for those who are uninformed.

There is a common belief that proper names are not to be translated. The author traced the transfer of urbanonyms in French translations of two Polish crime novels set in contemporary Warsaw. The analysis has been based on the techniques of translating proper names by K. Hejwowski (2004, 2015). The dominant techniques used in various categories of urbanonyms have been distinguished (simple transfer, transfer with spelling modification, translation). In the case of street names, avenues and squares derived from surnames, translators use inflectional neutralization. Another frequent technique is to add the qualifiers rue (‘street’) and quartier (‘district’) to the names of streets and neighbourhoods. In Polish, they are often omitted, which, in the case of street names, is unacceptable in French. Moreover, several techniques allowing removing a proper name or to replace it with a common noun have also been detected. All in all, the techniques applied for translating urbanonyms make it easier for the French recipient to follow the threads of the novel and to read foreign names. However, they deprive him/her of contact with some features of foreign names’ strangeness that characterize a different cultural area.

Routine formulas represent an essential challenge for foreign language teaching as a compound of typical communicative situations due to speech acts (in maintaining new and old business contacts, expressing emotions, and discourse organization), and as an important element of pragmatic language competence. The main subject of the reflection is the selection and presentation of formulaic expressions in selected course books for business German as a foreign language which are used in the academic context. In particular, the fields of business correspondence, business phone calls, and other common communicative situations were analyzed, as well as exercises and other didactic activities aimed at developing business foreign language skills.

The main objective of the study is to analyze language play specificities in outdoor advertising in Kyiv. The research approach is based on classifying the tricks of language play according to the levels of the language system, as the most appropriate approach for the analysis of this material. It has been discovered that various tricks of language play relate to derivational level (such as contamination, abbreviation, occasion word formation), lexical-semantic level (different kinds of puns), phonetic level and others. There are also some cross-level language tricks that combine lexical and derivation levels and so on. The article also deals with cross-language play, mainly the combination of Ukrainian and English words. It is underlined that language play is also a very interesting subject for cognitive sciences, and linguodidactic and

In the article the materials of the Novhorod-Siverskyi site research both in the 1930's, and relatively recently, are analyzed. First of all, attention is paid to the faunal collection. The faunal associations from old excavations are coherent, typical of a cold steppe environment from the glacial period, near a riparian forest. However, it seems to result to a mix between natural taphonomic complexes and animal remains associated with human activity. Judging by the flint collection from the old excavations, the site was inhabited by representatives of the Pushkari type. New research yielded two archaeological layers that are very poor in flint artefacts. Concerning fauna, the faunal spectrum is restricted in both layers, with the woolly mammoth, the woolly rhinoceros, the horse and the reindeer in the lower and upper layers. In the upper layer there are also the bison, the fox and the hare. According to taphonomic observations, the bones had remained for a long time at an open air before being buried, in subsurface in a wet environment but few submitted to precipitations in link with permafrost activities. Particularly in the lower layer (2) some remains appear to be in place, while others seem to have been imported by hydraulic phenomena, either from the top of the promontory or from the Desna River. In the upper layer (1), some bones show possible anthropogenic impacts of breakage, linked to marrow recovery. In both layers we have some cranial and postcranial elements, mainly from adults sensu lato which could correspond to human predation. They could correspond to temporary camps of quite small human groups, potentially occupied at the end of the cold season/beginning of the warm season.

Published: January 2022

The article presents the preliminary results of the analysis of individual burial complexes discovered at the biritual burial ground of the Saltiv culture in Chervona Hirka (Balakliia district of Kharkiv Oblast). During the work at the burial ground, 313 burials were examined, of which 191 were performed as inhumations, and 122 – cremations. Also, 18 cases were recorded at the burial ground when some burials were inlet into the filling of the burial pits of other burials without destroying the latter. At the same time, most often, the main burial was an inhumation according to the rite, and the burial inlet into the filling of the burial pit belonged to the category of cremations (Table 1). Among the complexes under consideration, the burials performed simultaneously (one-act) and those made after a certain period of time are presented. The latter are numerically dominant over one-act burial complexes. In 18 cases, 11 burials belong to paired ones, in 6 cases a burial contained the remains of three deceased. In the filling of burial No. 75/ k-4, the remains of three deceased were found, deliberately placed there. Thus, in Chervona Hirka burial ground, cases are presented of one burial pit usage for the simultaneous or different graves of 2—4 deceased. In these complexes, we tend to see the burials of close relatives, members of the same family (husband and wife, mother with children, minor children). An analysis of the sex and age composition of people buried in these complex burials allows us to speak of the existence of undivided families of the paternal or fraternal type among the population who left the Chervona Hirka burial ground, along with small families. The most striking evidence of the latter is the fixation of a group of 11 burials (6 inhumations and 5 cremations) on an area of 25 m2, the main one is the burial of a man accompanied by a horse (burial No. 75/ k-4) (Fig. 6: 1). At the same time, in the filling of three graves from this group (No. 75/ k-4, No. 36 and No. 74) there were burial complexes, deliberately placed there: Nos. 37, 38, 58, 59, 64, 71 (Table 1).

Published: January 2022

OBJECTIVES

The purpose of this study was to minimize unnecessary laboratory services for hospitalized neonates with hyperbilirubinemia by revising a local clinical practice pathway (CPP).

METHODS

A retrospective cohort study was performed to compare the number of laboratory tests and blood draws in patients hospitalized with neonatal hyperbilirubinemia before and after implementation of a revised CPP. The study included infants with neonatal hyperbilirubinemia <14 days old admitted after their birth hospitalization between April 2017 and October 2019. Primary outcome measures included the total number of blood draws and the number of laboratory tests obtained per patient and length of stay. Secondary outcome measures included 7-day readmission rate, charges, and discharge bilirubin level.

RESULTS

The median number of blood draws per patient after implementation of the CPP decreased to 2 (interquartile range [IQR], 2–3) compared with 3 (IQR, 2–3) before implementation (Poisson model–based estimated mean difference, 1.1; 95% confidence interval, 1.0–1.3; P = .018). The median number of laboratory tests per patient after implementation decreased from 4 (IQR, 3–6) to 3 (IQR, 2–4; Poisson model–based estimated mean difference, 1.3; 95% confidence interval, 1.2–1.5; P < .0001). There was no significant change in length of stay, readmission rate, charges, or discharge bilirubin level.

CONCLUSIONS

Implementation of a revised CPP was associated with a significant decrease in the number of blood draws and laboratory tests per patient for infants admitted to the hospital for neonatal hyperbilirubinemia.

Published: January 2022

Introduction: In Neotropical forests with high seasonality, climatic variables generally exert a strong influence on plant phenology. Objetive: To describe the reproductive phenology of eight tree species in a fragmented forest landscape, as well as to evaluate the seasonality and their phenological synchrony. Methods: The observations were performed over two years on the foothills of Los Farallones de Cali National Park, in southwestern Colombia. We applied circular statistics to detect seasonal trends, calculate intraspecific synchrony and identify correlations between phenophases and climatic variables. Results: Flowering and fruiting were significantly seasonal in most species. The flowering and fruiting patterns were annual (e.g. Henriettea seemannii, Ocotea aurantiodora, Schefflera morototoni, Lacistema aggregatum) or sub-annual (e.g. Eugenia cf. egensis, Erythroxylum citrifolium, Miconia minutiflora, M. rubiginosa). The open flower and mature fruit phenophases at the community level were continual and bimodal. Each species had high intraspecific population synchrony of open flowers and ripe fruits. Precipitation, relative humidity, temperature and solar irradiance were correlated to flowering and fruiting peaks, except in E. cf. egensis. Conclusions: The annual species showed high phenological synchrony, although the rainfall regime showed variations between years; thus, they seem to be less sensitive to climatic variation than the sub-annual species. Our results indicate that climatic variables partially control the flowering and fruiting rhythms of the eight tree species in this study.

Introduction: Morphometrics analysis is an efficient and low-cost technique used in studies of sexual dimorphism in turtles. Kinosternon scorpioides scorpioides, scorpion mud turtle, has a wide phenotypic variation, depending on the area of its occurrence. Objective: The objective of this work was to identify the anatomical sexual difference of K. s. scorpioides, adults and hatchlings, through morphometric analysis; and relate the weights of adult animals to environmental factors (temperature and rainfall) in Marajó Island, Brazil. Methods: The sample collection was carried out from March to September 2018, covering both the rainy season (January to July) and the dry season (August to December). For the biometric analysis, 95 adults and 21 hatchlings were used, in which the length and width of the carapace and plastron, height of the shell, and weight were measured (adults only). For the geometric morphometry analysis, 21 adults and 13 hatchlings were used, in which 27 coordinates of anatomical landmarks were inserted in each image of the carapace and 11 in the plastron. Hatchlings were sexed by histology which was enabled by the identification of the ovaries and testicles. Results: The results showed the existence of dimorphism in adults. The plastron and height were higher in females, which had a more rounded carapace than males. This characteristic may be related to the species' sexual strategy, where males impose copulation. Histologically, it was possible to identify the ovaries and testicles in the hatchlings, but there was no anatomical sexual difference, despite the tendency to differentiate in the analysis of carapace PCA. Conclusions: Sexual dimorphism in K. s. scorpioides may play an important role on its reproductive behavior, which is synchronized with environmental events. This fact suggests that the reproductive strategies of this species would be severely affected by changes in the ecosystem.
The Early Iron Age at Tell Abu al-Kharaz, Jordan Valley
Authors: Bürge Teresa
Published: January 2022

The present monograph by Teresa Bürge deals with the material culture of the city of Tell Abu al-Kharaz in the northern part of the Jordan Valley. The basis and starting point is an extremely well-preserved domestic compound dating from the early Iron Age – one of the most controversial periods of the Eastern Mediterranean: it follows the political and economic collapse of the Late Bronze Age and results in a re-structuration of the political and social organization, which – due to the present state of research – is well documented only for the later Iron Age. In addition to a detailed examination of the architecture, the find material, its contexts, the relative and absolute chronology, and the possible function of the building, the study aims at an integration of the evidence from Tell Abu al-Kharaz into a broader picture. Special attention is devoted to the economy and social organization of the early Iron Age town, to aspects of tradition versus innovation, and patterns of economic contacts and migration. Therefore, the study contributes to a better understanding of processes of continuity and change in social and political organization and cross-cultural relations of pre- and protohistoric societies.
Differentiation of the indigenous goat populations in Ethiopia based on morphometric features and zoometric indices: The primary step for conservation
Authors: Tade B. , Melesse A. , Betsha S.
Published: January 2022

Abstract. This study was conducted to describe the indigenous goat populations of South Gondar, Ethiopia based on morphometric traits and body indices. To this effect, morphometric measurements were taken from 512 goats (153 male and 359 female) of both sexes drawn from three districts (Farta, Fogera and Libokemkem). Twenty structural indices were computed from morphometric measurements. Results indicated that age at first kidding and kidding intervals was 13.6 and 8.39 months, respectively, with an average litter size of 1.54 kids. Sex affected (p<0.001) all quantitative traits except ear length (EL), rump width (RW) and fore canon circumference (FCC) being higher in bucks than in does. The effect of age was significant (p<0.001) for all morphometric traits except for EL resulting in a linear increase with advancing age in both sexes. Except for EL and scrotal circumferences (SC), all quantitative traits were (p<0.01) affected by district of the goats rearing. Accordingly, Fogera goats had higher live weight (LW), heart girth (HG), height at withers (HW), body length (BL), chest width (CW), rump height (RH), rump length (RL) and teat length (TL) than those of Libokemkem. Fogera goats had also the highest LW and HG compared with those of Farta. Conversely, the Farta goats had higher RW, BL, TL, RL, CW, chest depth (CD), and paunch girth (PG) than those of Libokemkem. Libokemkem goats were inferior in most of the studied morphometric traits. Both HG and HW variables were identified as best predictors of LW in both sexes. Structural indices indicated that the goat populations could be characterized as meat phenotype with short legs being well adapted to midland altitudes. In conclusion, goats reared in the region could have a genetic potential for meat production with very good prolificacy. The Fogera goats were particularly better in most morphometric traits indicating their suitability for commercial meat production. However, further on-station research is recommended to verify their potentials as meat animals for enhanced food security in the region.
Influence of duration of storage and pre-sowing electromagnetic treatment on the development of the primary root system of cotton seeds
Authors: Koleva M. , Radevska M.
Published: January 2022

Abstract. Seeds of five Bulgarian cotton varieties, stored for one and two years, were subjected to five pre-sowing electromagnetic treatments with different intensity and duration of exposure. It was found that the selected values of controllable factors had stimulating effect on the total length and total mass of sprout and root. The total length of sprout and root increased by 7.5-16.4% (p<0.05), the total mass of sprout and root increased by 7.8-12.7% (p<0.05). The best treatment options were 1[U=(8…5)kV, τ =(15…35)s] and 4[U=(6…3)kV, τ =(5…25)s]. Electromagnetic treatments had stronger positive effect on seeds stored for one year. Compared to the untreated control, corresponding to each storage period, the electromagnetic impact had stimulating effect for both storage periods: for the total length of sprout and root the increase was by 7.6-21.1% and 2.3-11.0% at option 4; for the total mass of sprout and root it was by 10.8-16.5% at option 1 and 4.5-9.1% at option 4, respectively, at one-year and two-year storage of seeds. In comparison with the control Chirpan-539 variety, untreated seeds, one-year storage, higher values for both studied characteristics were found only for seeds stored for one-year: for the total length of root and sprout at the varieties Natalia, treatment options 1 and 4, Nelina and Helius, options 2 and 4 and Chirpan-539, option 1; for the total mass of root and sprout at the varieties Nelina, options 1, 2 and 3 and Chirpan-539, option 5. Compared to the untreated control corresponding to each variety, the stimulating effect of the pre-sowing electromagnetic treatment for the two characteristics was found for all varieties, for both storage periods. The Helius variety was the most responsive to the electromagnetic impact, with the strongest stimulating effect for both characteristics, at the one-year storage of seeds the total length of sprout and root increased most strongly by 34.8-43.9% at options 1, 4 and 2[U=(6…3)kV, τ =(15…35)s], and the total mass of sprout and root increased by 48.5% at options 1.
Religion, Migration and the New African Diaspora
Authors: Neff Megan Anna , Cowden Richard G. , Masilela Lisanda , Counted Victor
Published: January 2022

The new African diaspora has emerged from the recent migratory movements of Africans. This population is tasked with finding effective methods of adjusting to new environments. Through the psychoanalytic lens of object relations, this article explores the role of religion in shaping migration experiences of the new African diaspora. It considers the psychological processes that intersect with religion to influence migrant adjustment. First, drawing from object relations theory, the role of early relational experiences in shaping self-concept is conveyed. Second, ways are explored in which religious phenomena can support transitional processes within a migration context. Third, the object relations framework is used to review some of the psychological tasks involved in the migration experience (e.g., processing of attachment disruptions, expansion of cultural identity). It is theorized that a migrant’s relationship with the sacred represents a transitional phenomenon that contributes to positive adjustment via a post-migration experience. The article concludes with some practical considerations.

Published: January 2022

Constructions related to products of maximal linked systems (MLSs) and MLSs  on the product of widely understood measurable spaces are considered (these measurable spaces are defined as sets equipped with \(\pi\)-systems of their subsets; a \(\pi\)-system is a family closed with respect to finite intersections). We compare families of MLSs on initial spaces and MLSs on the product. Separately, we consider the case of ultrafilters. Equipping set-products with topologies, we use the box-topology and the Tychonoff product of Stone-type topologies. The properties of compaction and homeomorphism hold, respectively.

ABSTRACT This paper aims to analyze the innovations introduced in the functions of the International Monetary Fund in the context of the 2008 economic and financial crisis. This promoted an action that aimed to strengthen the surveillance function through the adoption of the Integrated Surveillance. Thus, alongside the traditional conditionality based on an a posteriori implementation of adequate economic policies, a criterion of ex ante conditionality in the precautionary branches was also introduced or based on the economic characteristics of the country to be financed. Concerning traditional conditionality, it will be asked whether the IMF has adopted a less extensive approach than its role.

Abstract The purpose of the study was to investigate the association between single nucleotide polymorphisms (SNPs) in genes encoding estrogen receptors (ESR1 and ESR2, respectively) and delayed tooth emergence (DTE). This cross-sectional study was composed of biological unrelated children of both sexes, age ranging from 11 to 13 years old. DTE was defined when the successor primary tooth was still present in the oral cavity after its exfoliation time or the absence of the permanent tooth emergence into the oral cavity. Children were diagnosed with DTE when they had at least one delayed permanent tooth, according to age of exfoliation of each tooth proposed by The American Dental Association. Genomic DNA from saliva was used to evaluate the SNPs in ESR1 (rs9340799 and rs2234693) and ESR2 (rs1256049 and rs4986938) using Real-Time PCR. Chi-square or Fisher exact tests and Logistic Regression adjusted by age and gender were performed. SNP-SNP interaction was accessed by multifactor dimensionality reduction (MDR) analysis also adjusted by gender and age. The established alpha of this study was 5%. Among 537 included children, 296 (55%) were in the “DTE” group and the 241 (45%) were in the “Control” group. Age and gender were not statistically different among the groups (p>0.05). Genotype distribution of the SNPs rs9340799, rs2234693, rs1256049 and rs4986938 were not associated with DTE (p> 0.05). The models elected by MDR were not statistically significant either. Conclusions: The studied SNPs in ESR1 and ESR2 were not associated with permanent DTE.

Abstract The aim of the present in vivo study was to evaluate the bacterial contamination of sports mouthguards, surface roughness, and the efficacy of chlorhexidine gluconate spray in the disinfection of these devices. A randomized, blinded cross-over clinical trial was performed with twenty 9 to 13 years old children who practiced martial arts and participated in all phases of the study. They were instructed to wear mouthguards 3 alternated days a week for 1 hour and, after use, to spray sterile tap water or chlorhexidine 0.12%. The mouthguards were analyzed by MTT assay, Checkerboard DNA-DNA hybridization, and confocal laser microscopy prior and after use for 2 weeks. Data were analyzed by Wilcoxon and t-Student, and Pearson correlation tests, with 5% significance level. Were observed that mouthguards of the control group were more contaminated with cariogenic microorganisms than those of the chlorhexidine group (p<0.05). The mouthguards use of spray of chlorhexidine reduced significantly the bacteria contamination compared with control group (p = 0.007). The surface roughness of the mouthguards increased significantly after use, irrespective of application of chlorhexidine spray. A moderate correlation (r=0.59) was observed between surface roughness and the cariogenic microorganism’s contamination only for control group. Sports mouthguards had intense microbial contamination and increased surface roughness after its use. The use of chlorhexidine spray was effective for reducing the mouthguards contamination used by children.

Abstract This article reported two clinical cases in which the guided endodontics was used to perform the access to the root canals. The first case presents a 40-year-old female with a history of pain related to the left maxillary canine. After radiographic examination, the presence of severe calcification up to the apical third of the root canal, associated with a periapical radiolucency, was noted. In the second case, an 85-year-old male was referred to our service with pain upon palpation, at the right mandibular first molar. The radiographic images revealed the presence of endodontic treatment and a fiberglass post in the distal root canal, which was associated with extrusion of the filling material and a periapical lesion. The 3D-guides were planned based on cone beam computed tomography and intraoral digital scanning, which were aligned using a specific software. Therefore, implant drills could be guided up to the root canal length required for each case. In the first case, a surgical root canal was created and the patient was free of signs and symptoms after the treatment was completed. In the second case, it was observed that the fiber post was worn by the drill, allowing free access to the filling material. It was possible to perform the endodontic reintervention in a more predictable way and in less time. In both cases, the use of the guided endodontics allowed the preservation of a large part of the dental structure. The procedures were performed faster, without the occurrence of fractures and perforations.

Abstract To investigate the effect of the dimethyl sulfoxide combined with cross-linking agents on microtensile bond strength, silver nitrate penetration and in situ degree of conversion analysis of adhesives to the erosive dentin treatment with Cola-based soft drink. One hundred and sixty-six molars were assigned to 20 groups: (1) Treatment: Sound dentin; Erosive dentin; Erosive dentin treated with primer of dimethyl sulfoxide; Erosive dentin treated with DMSO primer containing proanthocyanidin and rivoflavin; (2) Adhesive systems: iBond Universal and Scotchbond Universal; and (3) adhesive strategy: etch-and-rinse or self-etch strategy. After restoration, specimens were sectioned into sticks to be tested. The data from microtensile bond strength (MPa), silver nitrate penetration (%) and in situ degree of conversion (%) were analyzed by (three- and two-factor ANOVA; Tukey's test α=5%). The application of dimethyl sulfoxide combined of not with cross-linkers improved all properties evaluated when compared to only erosive dentin treatment with Cola-based soft drink. However, only when dimethyl sulfoxide was combined to cross-linkers, the values of the microtensile bond strength, silver nitrate penetration and in situ degree of conversion in erosive dentin treatment with Cola-based soft drink was similar to sound dentin, for both adhesives and adhesive strategies. The application of dimethyl sulfoxide combined with the collagen cross-linking agent contributed to increasing the bond strength and degree of conversion in erosive lesion dentin, at the same time that significantly reduction of nanoleakage in this substrate.

Abstract This study describes a methodology to identify accessory root canals using the e-Vol DX software in CBCT scans. Accessory root canals are strategic shelters for microorganisms present in root canal infections. The identification of these small canals in periapical radiographic exams has limitations, besides being markedly limited accessibility to the action of endodontic instruments and to the antimicrobial agents. A significant number of accessory canals have sufficient diameters to be visible on cone-beam computed tomography (CBCT) images of high spatial resolution. Therefore, it may go unnoticed or even confused when there is no specific training for this type of diagnosis. The methodology consists in establishing thin slices (0.1mm or smaller) obtained from coronal, sagittal and axial slices. The method consists of the following steps: during navigation along the long axis of a root canal when finding a possible hypodense line of main root canal in a tomographic section (axial, sagittal or coronal), the navigation software lines of the multiplanar reconstruction (MPR) must be adjusted so that they are parallel and perpendicular to the hypodense line (parallax correction). Then, after judiciously adjusted, the accessory canal image will invariably appear as a line on one of the MPR tomographic slices, another line on another slice, and a dot on the third slice. The three sections of the MPR present images with the “line-line-dot” sequence. In this way, it is possible to identify an accessory root canal and also visualize it in volumetric reconstruction in a specific filter. The application of this method is easy to employed and may benefit the diagnosis when you want to visualize accessory root canals and distinguish it from root fracture line.

ABSTRACT: This study aimed to elucidate the sedative effect and physiological changes associated with the intramuscular injection of detomidine combined with morphine in horses. Six healthy crossbred horses, aged 2 to 10 years, were included. A crossover experimental design was used to compare the effects of intramuscular injection of 30 µg/kg of detomidine alone (IMD) and intramuscular administration of 30 µg/kg of detomidine and 0.1 mg/kg of morphine (IMDM). The degree of sedation, height of head above ground, were assessed at the time points before and 5, 10, 20, 30, 40, 50, 60, 75, 90, 105, and 120 minutes after drug administration, and heart rate, respiratory rate, systolic blood pressure, rectum temperature and intestinal motility were assessed at the time points before and 10, 20, 30, 40, 50, 60, 75, 90, 105, and 120 minutes after drug administration. The physiological parameters were analyzed using the Kruskal-Wallis test with Dunn’s post-hoc test and analysis of variance with t-test for independent samples and the sedation scores using the Friedman test and Mann Whitney U-test. P-values <0.05 indicated a statistically significant difference. IMDM promoted a higher sedative effect as compared to IMD, but the sedation occurred inconsistently. Additionally, a reduction in intestinal motility was observed with IMDM at 60, 75, 90, and 105 minutes after administration. IMDM promoted more variable sedation and prolonged reduction in the intestinal motility in the horses as compared to IMD.
A INCONGRUÊNCIA DO TAYLORISMO À INDÚSTRIA TÊXTIL COMO SISTEMA DE MÁQUINAS NO BRASIL E NOS ESTADOS UNIDOS
Authors: Cunha Elcemir Paço , Guedes Leandro Theodoro
Published: January 2022

RESUMO O presente artigo objetiva analisar a congruência formal e histórica entre o setor têxtil como sistema de máquinas (ou grande indústria) no Brasil e nos Estados Unidos e o taylorismo como método de ampliação da produtividade por meio da intensificação do trabalho na transição entre os séculos XIX e XX. Para realizar a análise, diferencia-se manufatura de grande indústria (sistema de máquinas), explicitando os métodos de ampliação da produtividade mais aderentes. Metodologicamente, a pesquisa foi realizada por meio de estudo histórico de caráter qualitativo quanto à abordagem dos dados colhidos para o período entre 1842 e 1946. A conclusão central aponta para a incongruência entre taylorismo e setor têxtil como grande indústria no qual se desenvolveram outros métodos predominantes de ampliação da produtividade, como o maior número de máquinas por operário, nos Estados Unidos, e o prolongamento da jornada de trabalho, no Brasil. A contribuição principal aponta para a importância da delimitação precisa do taylorismo como método de intensificação e da pesquisa concreta por setor em lugar de conceituação abrangente e da generalização abusiva.
RELATO INTEGRADO: EVIDENCIAÇÃO DE RISCOS RELACIONAIS PELAS EMPRESAS PARTICIPANTES DO PROJETO PILOTO NO BRASIL

Published: January 2022

RESUMO O Relato Integrado (RI) deve prover uma visão da qualidade das relações que a organização mantém com as partes interessadas e evidenciar os riscos que afetam a capacidade de gerar valor no curto, médio e longo prazo. Assim, este estudo tem o objetivo de investigar como os riscos relacionais são evidenciados pelas empresas participantes do projeto piloto do RI no Brasil. Realizou-se análise de conteúdo dos RIs de 11 empresas participantes do projeto piloto do RI. Os resultados evidenciam que apesar dos riscos relacionais possuírem representatividade na relação entre organizações, estes são divulgados de forma não padronizada, implícita e dispersa ao longo dos documentos. Ao classificar os riscos evidenciados nas categorias de riscos relacionais, observou-se predominância da evidenciação de riscos de potencial conflito e de não aprendizagem. Por outro lado, o risco de invasão não foi divulgado por nenhuma empresa. Para atender ao propósito do RI, as organizações devem torná-lo mais compreensível quanto a riscos relacionais e formas de mitigá-los. Uma orientação por parte do International Integrated Reporting Council quanto à evidenciação de riscos relacionais pode melhorar a padronização das informações divulgadas e o poder informativo do RI para os usuários externos.

RESUMO A Síndrome Respiratória Aguda Grave do Coronavírus 2 (SARS-CoV-2), causadora da Coronavírus 2019 (Covid-19), se alastrou, tornando-se em pouco tempo uma pandemia. A doença provocou a escassez de ventiladores mecânicos no mercado brasileiro e mundial. Esta pesquisa teve como objetivo compreender o desenvolvimento de ventiladores mecânicos destinados ao atendimento de pacientes acometidos pela Covid-19, focando em dificuldades e na configuração da inovação. Para tanto, realizou-se uma pesquisa exploratória, com abordagem qualitativa, um estudo de casos múltiplos. A coleta de dados ocorreu por meio de entrevistas semiestruturadas com os agentes inovadores. Os dados foram analisados por meio de análise de conteúdo. Os resultados demonstram que os equipamentos desenvolvidos constituem inovação frugal, uma vez que apresentam pelo menos quatro características desse tipo de inovação: acessibilidade e baixo custo; atendimento a determinada necessidade; uso de peças alternativas; e inovação. Os participantes apresentaram comportamento resiliente para vencer as dificuldades associadas ao custo de homologação; tempo, criatividade e distanciamento social; necessidades de conhecimento específico; e necessidade de trabalhar com margem de custo reduzida. A pesquisa apresenta uma contribuição para a compreensão do desenvolvimento da inovação frugal em contexto contingência, como foi o caso da pandemia, focando em indivíduos criadores e no processo de criação.

Abstract Life cycle assessment was carried out for a conventional wooden furniture set produced in Mardan division of the Khyber Pakhtunkhwa province of Pakistan during 2018-19. Primary data regarding inputs and outputs were collected through questionnaire surveys from 100 conventional wooden furniture set manufacturers, 50 in district Mardan and 50 in district Swabi. In the present study, cradle-to-gate life cycle assessment approach was applied for a functional unit of one conventional wooden furniture set. Production weighted average data were modelled in the environmental impacts modelling software i.e., SimaPro v.8.5. The results showed that textile used in sofa set, wood preservative for polishing and preventing insects attack and petrol used in generator had the highest contribution to all the environmental impact categories evaluated. Total cumulative energy demand for wooden furniture set manufactured was 30,005 MJ with most of the energy acquired from non-renewable fossil fuel resources.
O Ensino de Física à luz dos livros didáticos (Da Reforma Capanema à Lei 5692/1971)
Authors: Hosoume Yassuko , Martins Maria Inês
Published: January 2022

Foram pesquisadas quatro décadas de livros didáticos de Física, de 1940 a 1980, no âmbito da história dos conteúdos escolares, procurando caracterizar as propostas de ensino de Física no Brasil, identificando o contexto das políticas educacionais e suas relações com as políticas editoriais. O estudo considera os livros, através de seus autores, seus objetivos educacionais implícitos e explícitos, seus conteúdos específicos e suas propostas de desenvolvimento das atividades pedagógicas. A partir da década de 1940, o mercado editorial de livros didáticos e os autores se concentram em São Paulo, sendo professores de escolas públicas nos primeiros períodos (1940–1950) e professores de cursos preparatórios para o vestibular nas décadas seguintes (1960–1970), muitos deles com livros editados por até 3 (três) décadas. Embora tenham ocorrido no período três reformas educacionais, diferenciando-se por: valorização do pensamento cientifico teórico (década de 1940); alinhamento dos temas da física com as áreas da ciência física e acrescentando em sua formulação a importância do caráter experimental (década de 1950); formação tecnológica e profissional (décadas de 1960/1970), a proposta de ensino de Física concretizada em livros de mesma autoria mudou muito pouco, visando a sua adequação a cada nova demanda legal. Por outro lado, a chegada do PSSC no Brasil representa um marco para o ensino da Física, levando às reflexões que resultaram em projetos de ensino no início dos anos 1970, todos com sede em São Paulo, refletindo formas distintas no desenvolvimento dos conteúdos, desde uma visão mais cultural, com a Física bastante contextualizada e o caráter experimental bastante explorado, até projetos com conteúdos bastante teóricos e conceituais, semelhante ao desenvolvimento dos conteúdos propostos em universidades de formação de físicos ou professores de física. Pode-se dizer que a década de 1970 foi um dos períodos mais ricos em termos de proposições em ensino de física, com diferentes visões de física e de ensino.
