Authors: Ronzani Leticia Domingos , Bang Hannah , Kock Kelser Souza , Menegaz Phelipe de Souza , Martins Rafael Olívio , Back Netto Martins
Published: July 2022

ABSTRACT Objective: To evaluate the temporal trends of thoracolumbar fusion procedures performed by the United Health System in Brazil from 2009 to 2019. Methods: This was an observational ecological study based on data collected from the information systems under the aegis of DATASUS, especially the Hospital Information System, which manages the Hospital Admission Authorizations (Autorizações de Internação Hospitalar - AIHs). All patients who had undergone the procedures of interest, that is, elective and emergency short and long thoracolumbar arthrodeses, were included. The temporal trends of the procedures performed in Brazil and in its five regions were calculated using polynomial regression. Results: The temporal trend of elective thoracolumbar arthrodesis decreased, while that of emergency arthrodesis increased, with the peak in 2015, followed by a marked decline. Short fusions were more frequent in both elective and emergency modalities, and the South and Central-West Regions had the highest indices of procedures per million inhabitants during the entire 2009 to 2019 period. Conclusions: The temporal trends of thoracolumbar fusions performed by SUS have decreased over the last decade, a phenomenon which may be explained by the growing criticism of indications of the procedure in the current literature.

Published: July 2022

Abstract The cross-section of concrete-filled steel tube (CFST) columns is classified according to the local slenderness of the steel tube as slender, non-compact, or compact. There are analytical models to determine the axial force of locally slender CFST columns, however studies on load transfer from beams connected to these columns are scarce. This paper presents the process of the development and validation of a numerical model to simulate the behavior of Crestbond connectors applied to CFST columns with slender steel tubes, based on the results of experiments carried out. The numerical model presented can be used for the analysis and design of the load transfer in slender columns using connectors known as composite dowels.

Published: July 2022

The purpose of the present work is to present adaptation suggestions of activities from an English language textbook, to be used by blind students in the sixth year of Basic Education. In this qualitative research, inscribed in the area of Applied Linguistics, we sought to provide a Review of Literature on research about the adaptation of materials for blind students, which comprised our previous studies. Highlights of themes approached include the lack of research and of adapted materials for blind students, the lack of preparation of teachers to deal with the specificities of those students and problems in the development of autonomy and inclusion of blind students in class. In addition, we searched on those studies for understanding and ideas of methodologies and adaptations of didactic materials for the proposals developed in the English field. In a second moment, the sixth grade English textbook most chosen by public schools in Santa Maria in 2021, entitled “Way to English for Brazilian Learners - 6” (FRANCO; TAVARES, 2015), was analyzed. Furthermore, the analysis of the textbook revealed that the most relevant section to be adapted is the “Vocabulary Corner”, which encompasses vocabulary activities referring to all units of the book. After this process, adaptations for six activities in the book were suggested, built on the basis of the Literature Review, in order to make them inclusive and accessible for blind students.

Amaç

Yara iyileşmesi cerrahide yüksek morbiditeye neden

olabilen ciddi bir problemdir. Yara iyileşmesini hızlandırmak,

nekrozu veya iskemiyi önlemek için değişik

farmakolojik ajanlar çalışılmış ve halen yaygın olarak

çalışılmaya devam etmektedir. Yara iyileşmesinde

klinik pratikte topikal dekspantenolün geniş kulanım

alanları mevcuttur. Topikal dekspantenol hem yara

bakımında hem de dermatolojik hastalıkların tedavisinde

kullanılmaktadır. Bu çalışmamızda, ratlarda

oluşturulan deneysel yara modelinde lokal sildenafil

sitrat ve topikal dekspantenol uygulamalarının etkilerinin

karşılaştırılması amaçlanmıştır.

Gereç ve Yöntem

Çalışmada 200–250 gram arasında değişen 30 Adet

Wistar Albino dişi rat kullanıldı. Hayvanlar üç gruba

ayrıldı. Deney hayvanlarının anestezisini takiben sırt

orta kesimlerine 2 cm uzunluğunda tam kat kalınlıkta

deri defekti oluşturuldu. Yara pansumanında tüm hayvanların

yaraları steril % 0.9 NaCl solüsyonu ile yıkandıktan

sonra kontrol grubu olduğu gibi bırakılırken,

irigasyon sonrası 2. gruba %5’lik dekspantenol krem,

3. gruba % 10’luk sildenafil krem uygulandı. Ratlarda

yara boyutları 3., 5., 7., 10., 14. ve 21. günlerde ölçülerek

kaydedildi ve 21. gün tüm ratların sırt kısımlarından

insizyon hattını içerecek şekilde tam kat deri

çıkarılarak histolojik incelemeye alındı.

Bulgular

Tüm gruplara genel olarak bakıldığında günlere göre

yara boyutlarındaki küçülme ve histopatolojik bulgular

açısından istatiksel olarak anlamlı fark saptanmadı.

Sonuç

Sildenafil sitratın yara boyutunda önemli bir azalmaya

yol açtığı için yara iyileşmesi için topikal bir krem olarak

kullanılabileceğine inanıyoruz.

Her üç deneme alanının birlikte değerlendirilmesi sonucunda klonlar arasında istatistiksel olarak fark olduğu; G96 klonun, özellikle hacim gelişimi bakımından en yüksek değerlere sahip olup ilk sırada yer aldığı görülmüştür. 5. yaş sonunda, bütün deneme alanlarında büyüme bakımından saf türleri geçen hiçbir melez klonun bulunmamasına rağmen başarılı klonların arasında yer alan verimli üç melez klon (M77, M85 ve M46) ümit verici görülmüştür.
ENUMERATION AS A MEANS TO STRUCTURE THE PROCESSES DOMAIN WITHIN ECONOMIC SYSTEM
Authors:   Taras Shevchenko National University of Kyiv, Antonova Maryna
Published: July 2022

This paper explores cognitive aspects of enumeration. The material of the study is economic discourse. Enumeration is considered as a means to structure and represent conceptual information within economic discourse. Cognitive approach to enumeration involves analysing both homogeneous and heterogeneous enumerative series. In economic discourse semantically homogeneous enumerations are represented by economic spheres of human activity, while semantically heterogeneous enumerative series presuppose correlation between economic and other spheres of human activity. In economic discourse the structure of enumerative sequence is represented by linear and hierarchical constituents. The linear structure may consist of at least two different components of enumeration. In some cases more than one linear enumeration is used in one sentence. In case of a hierarchical structure one of the elements of the main enumerative sequence is subdivided into a subordinate enumerative block. The analysis of enumerative series provided conceptual knowledge represented by the following domains within economic system: the processes domain, the institutes domain, the instruments domain and the indicators domain. The processes domain is analysed in this article. Macroeconomic processes, namely globalisation, regionalisation and transition economy are represented by semantically homogeneous enumerative series. The study of semantically heterogeneous enumerative series allowed to structure knowledge about the macroeconomic processes of globalisation and regionalisation, as well as the microeconomic investment process. Homogeneous and heterogeneous enumerations name, specify, categorise and define the economic system constituents, as well as determine their potential and consequences for the economy.

BACKGROUND: Occupational morbidity, which is directly related to working circumstances is one of the primary markers that characterize occupational health risk. Thus, it is necessary to study the working conditions and occupational diseases, which form peculiarities in enterprises of various economic sectors, followed by the development and implementation of targeted interventions aimed at creating safe working conditions and preserving employees health.
AIM: to study industrial risk factors, occupational pathology main forms, and the timing of its development among employees at enterprises of various economic sectors.
METHODS: We studied the acts of occupational diseases investigation, sanitary, and hygienic characteristics of working conditions, and medical records of 339 patients who were diagnosed with occupational diseases by the Ufa Research Institute of Occupational Medicine and Human Ecology in 20152019.
RESULTS: It was discovered that the highest prevalent occupational diseases were diagnosed among workers of manufacturing industries and enterprises who engaged in mining with harmful working conditions (3.13.3) while conducting a retrospective in-depth analysis of occupational disease cases. Musculoskeletal system and connective tissue disorders predominated in the structure of the occupational disease. The largest number of patients had 3035 years of work experience in harmful working conditions. Based on this research, targeted measures have been developed to create safe working conditions and alleviate the risk of occupational diseases.
CONCLUSIONS: According to the available material, a retrospective in-depth analysis of occupational disease cases revealed that workers in the manufacturing industries and enterprises engaged in mining were more at risk of developing disorders (46.1, 20.6%). It was discovered that the development of occupational diseases depended on the exposure intensity of harmful production factors and exposure time. The risk of occupational diseases is raised with increasing time of working in harmful working conditions (class 3.13.4). The greatest risk of occupational diseases was observed within work experience from 3035 years. The structure of the analyzed occupational diseases cases was dominated by ailments of the musculoskeletal system and connective tissue (43.4%), injuries, poisoning, and some other consequences of external causes (17.5%), and diseases of the ear, and mastoid process (15%). The analysis of cases of occupational diseases should be used as the basis to measure development aimed at reducing the risk of their emergence and preserving employees health.

Effect of Variation of SiC Mass Fraction on Mechanical Properties of Al-SiC Composite Using Stir Casting Method
Authors: Sumarji Sumarji , Albajili Naufal Fardio , Darsin Mahros , Sakura Rahma Rei , Sanata Andi
Published: July 2022

Al-SiC is a composite composed of AA6061 as a matrix and SiC as a reinforcement particle. The variation of mass added will affect the mechanical properties of the composite because Al-SiC is hardenable, which means that its mechanical properties can be improved by adding the reinforcement component. However, an excessive portion of SiC leads to a decrease in mechanical properties. The purpose of this study was to find the optimal composition of the addition of SiC into the aluminium matrix to gain maximum tensile strength and hardness. The mass fraction variation that would be used in this composite was the addition of 6%, 8%, and 10% SiC with the addition of 1% Mg as a wetting agent. The mixing process used the stir casting method. The process of adding SiC and Mg was carried out by melting the aluminium while stirring it for a certain time before it went to the furnace. The ASTM E8/E8M standard was used for observing the tensile strength of the specimens. Machining was carried out before testing. The specimens were also tested for hardness using the Rockwell hardness method. The result shows that the addition of SiC at the amount of 6%, 8%, and 10% SiC increased the ultimate tensile strength by154.10 MPa, 175.01 MPa, and 198.14 MPa, respectively. Similarly, the hardness also increased up to 30.1 HRF, 48.1 HRF, and 66 HRF, respectively. Microstructure observation also confirmed that a 10% SiC fraction results in less defect and good wettability. The addition of 10% SiC and 1% Mg resulted in maximum tensile strength and hardness and the best microstructure.

Published: July 2022

Many studies were conducted to maintain the environment by reducing the waste, especially pineapple peel waste. This study aims to explore the effect of various pressure of the homogenization process on bacterial cellulose membrane surface morphology and structure produced using extract of pineapple peel waste. The methods include the preparation of pellicle samples from the product of the fermentation process of Acetobacter xylinum using a medium from the extract of pineapple peel waste. Bacterial cellulose pellicles were crushed using a blender. Mashed bacterial cellulose pellicle then homogenized in High-Pressure Homogenizer with pressure variation of  0 bar, 150 bar, 300 bar, 450 bar, dan 600 bar then cast into a mold. The bacterial cellulose solutions were dried in an oven at 60°C for 8 hours. The dried bacterial cellulose membrane was analyzed using XRD for the structure and SEM analysis for the morphology. The results indicate that the crystalline properties of BCM were shifted after being treated by various pressure processing in a High-Pressure Homogenizer. It was found that the High-Pressure Homogenizer with higher pressure reduced the peak intensity, decreased crystalline index from 87% to 70%, and decreased the degree of crystalline from 88% to 77%  without changing the cellulose structure. The higher pressure of the homogenization process causes the porosity of the membrane to be decreased.

Published: July 2022

Experimental research has been conducted on the effect of ignition timings on the characteristics and performance of gasohol engines such as power, torque, specific fuel consumption, and thermal efficiency. The fuel used in this research is pure gasoline and a mixture of 50% bioethanol (BE50). The results show that the ignition timing that gives the maximum effect occurs at the top and bottom dead points of 9 degrees for gasoline and 12 degrees for BE50 fuel. Furthermore, the maximum power is obtained at 6,500 rpm, and at an ignition time of 12 degrees BTDC the maximum power generated is 4.63 hp, while for an ignition time of 9 degrees BTDC the power generated is 3.38 hp which occurs at 6500 rpm. These results indicate that there is an increase in power of 6.4%. Moreover, the results also show that for optimal gasoline conditions, the amount of energy consumed at an engine speed of 7000 rpm is around 15705.78 kcal/hour, and for BE-50 it is around 12582.03 kcal/hour, where there is a reduction of about 25.44 %. However, in general, it can be seen that during optimal ignition, there is a saving in fuel consumption in the gasoline-BE50 mixture, while at the same time producing a fairly large thermal efficiency. These results indicate that BE50 has the potential to be used as an alternative fuel in small gasoline engines.
