Authors:   , Wilson Olivia R. , Magenau Andrew J. D.
Published: November 2022

This PhD thesis explored the utility of air-stable, alkylborane-amine complex initiation as a synthetic toolkit for oxygen mediated and room temperature polymerization to assemble diverse, polymeric materials with macromolecular control. The first aim of this thesis demonstrates alkylborane initiated thiol-ene click chemistry as a method for rapid and in situ, chemically triggered initiation of highly loaded and thick nanocomposites. The second aim introduces alkylborane initiation of thiol-yne polymerization for synthesis of reprocessable networks toward covalent adaptable composites. The third aim illustrates a versatile adhesion platform for low-surface energy polymers through alkylborane initiated graft polymerization to substrate surfaces. The fourth aim elucidates mechanistic features of alkylborane initiated reversible addition-fragmentation chain transfer (AI-RAFT) polymerization. Through these aims, complementary radical chemistry mechanisms initiated through alkylborane-amine complexes are developed such that polymer synthesis is oxygen tolerant and conducted at room temperature.

Authors: Luengo Aguirre Maite
Published: November 2022

En los años noventa proliferan las creaciones artísticas en torno a los cuerpos por parte de las artistas. Considerando la capacidad historiográfica de las exposiciones, analizamos el modo en que estas autoras están siendo tratadas en el contexto vasco. Para ello, comenzamos presentando las novedades del caso pionero de Genealogías feministas en el arte español:1960-2010 del MUSAC de León (2012-2013), en el cual se mencionaba la tendencia en cuestión. Después, examinamos el tratamiento recibido en los catálogos de cuatro exposiciones realizadas en la CAV. Por una parte, estudiamos la principal exposición de los años noventa de artistas mujeres, El puñalito y un puñao (1996); por otra parte, tres muestras de la recién comenzada década de los veinte: Bigarren bidea. Zeru bat hamaika bide (2021-), Womanology. Colección José Ramón Prieto (2021) y Baginen Bagara. Artistas mujeres: Lógicas de la (in)visibilidad (2021-2022).

Jó nexusok és rossz társaságok : Foglalkozási miliők és kapcsolathálózati erőforrások reflektív megközelítése komparatív háttérrel
Authors: Tardos Róbert
Published: November 2022

Az International Social Survey Programme (ISSP) 2017-es kapcsolathálózati modulja nagyszabású komparatív keretek közt első alkalommal alkalmazott foglalkozási pozíciógenerátort, annak egy tíztételes rövid változatát. A szociológiai kutatásokba az elmúlt évtizedben bevezetett reflektív bipartit metodológia egy újszempontú adaptálása a relációs erőforrások finomabb megragadását tette lehetővé a különböző foglalkozási ismeretségek eltérő pozíciós értékének figyelembevételével. A tanulmány kiemelten foglalkozik az alkalmazott eljárás és az ennek során kialakított mutatók tartalmi érvényességével, magyarázóképességével és szerkezeti koherenciájával. Az új módszer révén inkluzívabb és inkább presztízsorientált kapcsolati minták eltérő válfajainak vizsgálatára kerülhetett sor, a „negatív erőforrásokra”, a „nem annyira hasznos” társas miliők körvonalazására külön súlyt helyezve. Az eredmények plauzibilitásának tesztelésére a felvétel 30 országra kiterjedő komparatív adatbázisa adott lehetőséget. Az exploratív jellegű elemzések a kialakított miliőváltozók jelentős, a személyes siker bizonyos összetevői esetében a hagyományos társadalmi-demográfiai tényezőkhöz mérhető befolyását jelezték. A presztízsorientált mozzanatok szerepe Kelet-Közép-Európában és ezen belül Magyarországon különösen hangsúlyosnak bizonyult. Az egyéni szintű elemzéseket kiegészítő országszintű vizsgálódások számottevő összefüggésekre utaltak a hierarchikus jellegű kapcsolódási minták és a makroszintű társadalmi integráció olyan tényezői között, mint az askriptív vonatkozások befolyása a kapcsolati erőforrások alakulásában, a viszonosságnormák kulturális hangsúlya, a strukturális és kulturális vonatkozások együttes szerepét jelezve a csoportközi kapcsolatok hasadásaiban.

Published: November 2022

Objectives: To analyze perceptions about multiple community-engaged oral health research partnerships with various local Hispanic-serving institutions and community-based organizations occurring in Indiana from 2010 through 2020, via interviews with actors involved in those partnerships.
Methods: We designed key informant interview questions based on a literature review to inform the approach at synthesizing perspectives from community partners and academic allies. Statements were categorized using thematic analysis and grounded theory.
Lessons Learned: Forty percent of respondents stated that community-engaged research projects connect communities with educational information about dental care and low-cost resources. In terms of capacity building, about half of respondents felt these projects had a positive impact.
Conclusions: Community partners defined positive impact as increasing access to dental care educational resources, helping to enhance communication networks through social media with community partners, and contributing to local Hispanic health education through TV, internet, and radio partnerships. The partnerships uniting Hispanic groups and academic allies appear to have helped set a foundation of trust to support current and future efforts in Indiana.

Authors: Banik Arijita , B.M Soumya , Bijjaragi Seema , Kulkarni Vardendra , H.R Chandrasekhar
Published: November 2022

: Gastrointestinal ganglioneuromatosis is a rare benign neural neoplasm, consists of hyperplasia of nerve fibers, ganglion cells, and schwann cells in the wall of stomach and intestine. The disease may affect any part of the gastrointestinal tract but involvement of stomach is extremely unusual. Mainly are of three types: polypoid ganglioneuromas, ganglioneuromatous polyposis, and diffuse ganglioneuromatosis. To our knowledge, only two cases were reported as diffuse ganglioneuromatosis located in the stomach.

: 27-years male patient, admitted with complaint of dysphagia for both solid and liquid and recurrent non-bilious vomiting since 1 week underwent Billroth - 1 procedure and antral segment of stomach was sent for histopathological examination. A histopathological diagnosis of Diffuse Gastric Ganglioneuromatosis with muscular mural hypertrophy was made. The presence of ganglion cells and positive staining for S-100 and NSE confirms the diagnosis.

Obstructive gastrointestinal symptoms with a possibility of diffuse ganglioneuromatosis is mainly a disease of young children and infant. But an adult patient, which is an unusual age group, presenting with obstructive gastrointestinal symptoms, the rare possibility of Diffuse ganglioneuromatosis and intestinal neuronal dysplasia should be considered and investigated in order to avoid unnecessary and extensive surgical intervention.

Authors: Panda Subhajit , Veer Ram
Published: November 2022

Information is now considered to be essential to daily life. Libraries act as a hub for always giving the correct information to the right individuals. User studies must be acknowledged as a crucial component of the information packages. Libraries and other information providers should be aware of how people find information to improve the services they offer. This paper describes a survey designed to determine the information-seeking behaviour of Teachers and Students at Jan Nayak Ch. Devi Lal Vidyapeeth, Sirsa. Almost 200 respondents (44.4%) are chosen for the study from the 450 targeted samples. Additionally, a systematic, closed-ended questionnaire was used to gather the data. This study calculates the weighted average of the supplied criteria in addition to percentage analysis in order to make the acquired data more visible and easier to interpret. According to the study's findings, the targeted samples are likely to conduct their own independent research and encounter certain challenges because there are few pertinent information sources available in libraries. The report also recommended expanding informal communication as a way to facilitate information flow.
A comparative study of outcome of radial head fracture treated with radial head replacement and radial head excision alone
Authors: James Boblee , Varma Narendra , Anand Gokul
Published: November 2022

: Radial head fractures are the most common fractures of the elbow with an estimated incidence of 2.5 to 2.9/10,000 people/ year. The incidence of radial head fractures is reported to be between 1.7 to 5.4 percent of all fractures.

: This study aims to assess the clinical outcome of excision arthroplasty and prosthesis replacement in treatment of comminuted radial head fractures.

: Patients with radial head fracture presenting to orthopaedics department and emergency room were included for the study. Excision arthroplasty was performed in 25 patients and replacement arthroplasty was performed in 25 patients. The functional outcome of both the procedure were compared using DASH, MEPS and Broberg and morrey scoring system.

: Based on the DASH score Replacement group showed good improvement at the end of the 6 month follow-up with the mean score of 15.9 (P=0.042). Based on the MEPS score the mean MEPS score showed replacement group had a good improvement at the end of 6 month follow-up with the mean score of 15.9 (P=0.042).

: From this study we concluded, radial head replacement is a reasonable option for unreconstructable radial head fractures. Radial head replacement can achieve effective radiocapitellar contact that will improve the stability in valgus, posterolateral, and axial loading of the forearm. This treatment option has satisfactory short- and mid-term results even with other combined elbow injuries.
Challenges in discharging elderly patients post hip fracture – Functional outcomes
Authors: Yadav Rashmi , Chawla Pushkar , Kumar Ritabh
Published: November 2022

The purpose of this study is to realize the challenges experienced by elderly patients with hip fracture and their caregivers after discharge. A total of 65 files of elderly hip fracture operated patients were assessed and out of them responses from 53 patients collected through telephonic conversation over a period of 3 weeks. The responses received from the patient and their attendants were evaluated using the EQ-5D quality of life tool and their challenges noted.

The most common fractures reported in the elderly are at the wrist, spine and hip. Hip fractures in elderly generally occur after a simple fall. If timely medical attention is not provided or appropriate care not taken the future of the patient after a hip fracture is certain – a dramatic reduction in the quality of life and possibly the beginning of the end of life. The purpose of this study is to evaluate the outcomes of elderly patients with hip fracture following surgery and the challenges they experienced after discharge from the hospital.

A total of 53 patients were selected for the study who underwent hip surgery at Indian Spinal Injuries Centre. This is a descriptive study carried over a period of 13 months from August 2019 to August 2020. EQ-5D is used to characterize current health status of the patients. It consists of five domains and a visual analogue score. Feedback was collected from the patients and their attendants over telephone with a minimum follow up of 3 months. VAS score was calculated for every patient individually. Collected data was entered in MS Excel sheet. Challenges faced by the patients and their caregivers were documented.

Out of 53 patients, 12 had died (22.6%), 07 patients responded themselves to the call and 34 calls were responded by the care givers. Most of the patients had intertrochanteric fractures 56.6% (30 patients) followed by neck femur fracture 24.5% (13 patients). On average every patient was suffering from a minimum of two comorbidities. The average length of hospitalization was 6.8 days.

: This study suggests that integrated care involving geriatricians in pre-operative optimization of the patient should come in immediate practice. The role of post-surgery rehabilitation is invaluable but often an underestimated modality. The concerns of the patients and their family members regarding home care after discharge are genuine and need to be addressed. Information sharing is the key to reducing anxiety. Consideration for a cost-effective step-down facility must be considered by private institutes and government authorities.
Biomechanical effects of the tibial slope angle change on total knee prosthesis: 3D finite elements analysis
Authors: Arı Bunyamin , Korkmaz Murat , Özer Alaettin
Published: November 2022

: In total knee arthroplasty, finding the correct tibial slope angle while placing the prosthesis affects the joint load. In our study; the load on the tibial insert and the notch of the insert as a result of flexion of the knee joint 0-30-60-90 degrees at each inclination in prostheses applied with posterior inclination angles of 0,3,5 and 7 degrees was examined in the three-dimensional right knee finite element structural model. In this way, it was aimed to reveal at which slope the resulting load is the lowest.

The finite element structural model was created using the 3D 2.5 number right knee solid model. Two types of analysis were performed to examine the effect of angle change of the PE Insert on tibia component; static structural analysis with static loads at certain fixed flexion angles, and transient analysis with time for varying loadings at dynamically changing flexion angles with rotation of the knee between 0-90 degrees.

In the 0 and 30 degree models, the least load on the tibial insert was found at 7 degree tibial slop angle (11.6 and 9.87 mpa, respectively), in 60 and 90 degree models at 5 degree tibial slop angle (9.07 and 11.4 mpa respectively). In the models of 0 and 30 degrees, no pressure occured on the tibial insert notch at 3,5,7 degrees of tibial slop angles, while in the 60 degree model, a pressure of 0,153 MPa occured at all 0,3,5,7 degrees at 0 degrees tibial insert slop angle and this pressure was centered at the junction with the tibial insert.

The higher the load on the tibial insert, the greater wear of the tibial insert in the knee prosthesis. For this reason, it is important with which slop angle the tibial insert should be placed during surgery.

A Three-Node Triangular Constant Strain Element for Evaluation of Stress Concentration Factor of a Rectangular Thin Plate Under Tension Load
Authors: Fethallah Amara , Deghboudj Samir
Published: November 2022

In many engineering fields such as aerospace, marine, automotive and mechanical, the design of planar structures consisting of rectangular plates commonly requires the use of holes as a technological solution in fastening assemblies. The major goal of this research is to examine the impact of stress concentration factors (SCF) in the specific case of planar structures, highlight their relevance as a potential source of structural failure, and compare the various techniques employed to gauge their magnitude. Particular emphasis will be placed on rectangular plates with holes since these plates' shape discontinuities alter the stress field, leading to a local increase in the stress field that, if not accurately predicted and analyzed at the design stage, could endanger the entire structure. For the studied case (rectangular plate with central hole subjected to uniform tensile field), a new finite element formulation based on 3-noded triangular element has been suggested to estimate the field variables (stress). MATLAB programming has been developed by considering this element. Analysis has been carried out for the same structure (rectangular plate) with analysis software Abaqus. Finding was compared to several analytical solutions published in the literature, based on Heywood, Howland, and Flynn formulations. Obtained results were in good agreement.

Published: November 2022

The results of numerical studies of the utilization of sunflower husk pellets obtained by simulating the air gasification process in downdraft gasifier and subsequent purification of the produced syngas from CO2 are presented. Numerical studies were conducted with varying the air-fuel ratio from 0.25 to 0.5 to define the optimum value of this coefficient to obtain gas of a given quality. It was determined that with increasing oxidizer consumption the calorific value of syngas decreases from 3179 to 1971 kJ/m3, due to the increasing concentration of nitrogen and carbon dioxide, and the gasification efficiency increases from 38 to 59 %. The optimal value of the oxidizer excess coefficient for the air gasification of sunflower husk pellets is 0.35.

Authors: Smith Rozanne , Marx Ben
Published: November 2022

South African corporate failures and audit failures, including those of VBS Bank, Tongaat, Steinhoff and KPMG, have exposed vulnerabilities in audit quality and the role of governance failures in auditing firms. In auditing firms, good corporate governance principles are not always followed. Additionally, South Africa does not have a corporate governance code that governs auditing firms, nor is there a sector supplement to the King IV Report on Corporate Governance that applies to other industries. To identify areas for improvement in South Africa, this study aimed to ascertain the current corporate governance practices in South African auditing firms and compare them to the United Kingdom (UK) Audit Firm Governance Code. A structured questionnaire based on the UK Audit Firm Governance Code was used to collect qualitative data. Nine large and medium-sized South African auditing firms with 20 or more auditing partners made up the population. The literature study emphasised the value of good corporate governance in auditing firms, as well as the difficulties these firms encounter with corporate governance. The review also emphasised the absence of codes and standards regulating corporate governance in auditing firms. The empirical results highlighted the resultant inconsistencies in corporate governance application in South African auditing firms. Areas requiring improvement were identified in the study.

Authors: Etemadi Milad , Mohammadi Shadi , Nikbakht Mohammad Hossein , Ghazavi Olia
Published: November 2022

Introduction: Nasal fracture is the most common fracture of the maxillofacial region, so surgeons’ and patients’ satisfaction after closed reduction from aesthetic and functional (including the effects of respiration and olfaction) perspective is important. The aim of this study was to evaluate the satisfaction of surgeons and patients with the appearance and function of the nose after closed reduction surgery during 6-12 months after surgery to improve the outcomes of this procedure.
Materials & Methods: This descriptive-analytical and cross-sectional study was performed on 90 patients in Alzahra and Kashani hospitals of Isfahan during the years 1397-1398 who underwent a closed reduction of nasal fracture within 6-12 months after surgery. All patients and surgeons answered questions about aesthetic and functional outcomes and the need for septorhinoplasty after closed reduction. Pearson correlation coefficient, t-test and paired-sample t-test were used to analyze the data. P value less than 0.05 was considered as a significant level.
Results: About 55% of patients were satisfied with the aesthetic outcome and 38.8% expressed they would consider further surgery to correct the residual nasal deformity. The mean score of surgeons’ satisfaction for nasal aesthetics and function was 3.74 and 3.50. Surgeons expressed that the patients’ requirement for septorhinoplasty is low to moderate.
Conclusion: Satisfaction of the patient and the surgeon with the nasal closed reduction was in high-medium range. Also, according to both patients’ and surgeons’ opinions, requirement for septorhinoplasty surgery has a significant and direct relationship with aesthetic issues and also obstruction of the airway following a nasal bone fracture.

Published: November 2022

Introduction: The relationship between dental caries in children and abnormalities in their body mass index is still controversial. The aim of this study was to evaluate the association between Body Mass Index (BMI) and Severe Early Childhood Caries (SECC).
Materials & Methods: In this case-control study, 150 children with SECC (case group) and 150 caries- free kids for the control group were recruited from a number of Isfahan city’s private clinics in the year 2019.Parameters including weight and height were measured, and BMI (kg/m2 ) was calculated. The subjects were categorized based on BMI adjusted for age and gender as: underweight (<5th percentile), healthy weight (5th to <85th percentile), overweight (85th to <95th percentile), and obesity (≥95th percentile). The data was analyzed by using Chi-squared, Fisher’s exact test, and Mann-Whitney by considering a significance level at 0.05.
Results: There was a significant difference in the frequency of weight groups between the two groups of children without caries and with severe caries (p value = 0.007). There was a significant difference in the frequency of weight groups between boys and girls in the two groups of children (p value < 0.001). Frequency of weight groups in the age groups of 2, 3, 4 and 5 years there was a significant difference between the two groups of children (p value < 0.001). The mean body mass index in children with severe dental caries was significantly lower than children without caries (p value < 0.001).
Conclusion: According to the findings, a majority of children with SECC were underweight compared to caries free children, suggesting SECC may adversely affect growth.

Published: November 2022

Objective: Musculoskeletal involvement in brucellosis is very important. This study aimed to evaluate the magnetic resonance imaging (MRI) findings and hematological parameters as a predictive value for the diagnosis of musculoskeletal brucellosis.
Methods: This prospective case-control study was conducted between June 2011 and November 2019 in a university hospital. Ninety-nine patients with the confirmed diagnosis of brucellosis without musculoskeletal involvement and forty-three brucellosis patients with musculoskeletal involvement were examined. The hematological, biochemical parameters, and radiological imaging findings of both groups were recorded. These parameters were statistically compared between the two groups.
Results: The mean age of the patients (non-involvement group) and musculoskeletal involvement groups was 44.04 ± 23.11 and 37.92 ± 24.80 years, respectively (P = 0.062). C-reactive protein (CRP) and alkaline phosphatase (ALP) levels were significantly higher in the musculoskeletal involvement group (P < 0.05). The lower lymphocyte level was statistically significant in this group. Based on the receiver operating characteristic (ROC) analysis, the sensitivity and specificity were 70% and 65% for ALP, 77% and 58% for CRP, 83% and 45% for lymphopenia, respectively. There was no statistically significant difference between the two groups in terms of the other hematological and biochemical parameters. Spondylodiscitis (34.8%) was the most common MRI finding in patients with musculoskeletal involvement.

Pseudomonas spp. são comumente relacionadas com a deterioração de produtos lácteos. Algumas espécies desse gênero, além de se multiplicarem em temperaturas de refrigeração, produzem enzimas hidrolíticas responsáveis pela deterioração do leite e seus derivados. A metaloprotease AprX é uma das proteases produzidas por Pseudomonas. Essa enzima, codificada pelo gene aprX, é resistente ao calor e capaz de manter sua atividade mesmo após tratamentos térmicos comumente utilizados na indústria de laticínios, como pasteurização e tratamento UHT (Ultra-high Temperature), resultando em perdas das características sensoriais e em problemas como a gelificação. Algumas cepas de Pseudomonas também podem produzir enzimas lipolíticas termorresistentes. Essas enzimas catalisam a hidrólise de triacilgliceróis, resultando na liberação de ácidos graxos associados à deterioração de muitos alimentos. Esses ácidos contribuem para o sabor forte, rançoso e de sabão de produtos lácteos. Em vista disso, o objetivo deste trabalho foi destacar, por meio de uma revisão de literatura, os desafios enfrentados pela indústria de lácteos frente às proteases e lipases produzidas pelo gênero Pseudomonas.

Objectives: Electrical appliances are source of radiofrequency radiation (RFR). The effects of RFR on the organism are not fully understood. Endoplasmic reticulum (ER) stress is appeared by the accumulation of misfolded proteins in ER lumen. The aim of this study was to investigate the effects of 900 and 2100 MHz RFR exposure on the ER stress pathway in rat thymus.
Methods: Rats were divided into six groups: 1 week (w) and 10 w Sham rats were kept in plexiglass tubes for 2 hours/day without RFR, experiment groups were created as 1-w (acute) and 10 w (chronic) rats which exposed to 900 and 2100 MHz RFR for 2 h/day. There were 20 male Wistar rats in each group. Immunohistochemistry stainings were performed GRP78, CHOP, Cleaved (Clv.) Caspase 3 and Caspase 12.
Results: Expressions of GRP78 and Clv. Caspase3 in RFR groups is significantly higher than sham groups (p < 0.001). In 900 MHZ-1 w rats, high levels of GRP78 expressions were at the cytoplasm of epithelial reticular cells. In other groups, GRP78 expressions were seen also at thymocytes. Expressions of CHOP in RFR rats were higher than sham rats (2100 MHz /Sham for 10 w; p < 0.001, 900 MHz /Sham for 10 w; p = 0.004, 900 MHz /Sham for 1 w; p = 0.003). Localization of CHOP expressions was at the nucleus membrane and cytoplasm. The expression of Caspase 12 in RFR rats was higher than sham rats (900 MHz /Sham for 1 w; p = 0.006, other groups; p < 0.001).
Conclusions: This study demonstrates RFR exposure could increase levels of ER stress pathway proteins and could cause apoptosis.

Fonksiyonel gastrointestinal bozukluklar, herhangi bir yapısal ya da biyokimyasal

patoloji olmaksızın, çeşitli kombinasyonlarda, kronik ve tekrarlayıcı gastrointestinal

semptomları içeren bir sendromdur. Bugüne kadar, bu grup hastalıkların tanımlanması ve

sınıflandırılmasında çeşitli kriterler geliştirilmiş ve bunlardan en sık kullanılanı Roma kriterleri olmuştur.

ROMA III kriterlerine göre yaptığımız çalışmada, sorgulamaya aldığımız populasyon genç yaştaki sağlık çalışanları idi.

Fonksiyonel gastroduodenal bozuklukların tümünün sıklığı populasyonumuzda % 26,2 idi ve bu oran erkek-kadın ya da doktor-yardımcı sağlık personeli arasında istatistiksel farklılık göstermiyordu. Fonksiyonel gastroduodenal bozuklukların büyük çoğunluğu fonksiyonel dispepsi, fonksiyonel dispepsinin de büyük çoğunluğu post-prandiyal distress(sıkıntı) sendromu idi. Epigastrik ağrı sendromu nadirdi. Bunu geğirme bozuklukları ile

bulantı ve kusma bozuklukları izlemekteydi. Fonksiyonel dispepsi sıklığı bizim çalışmamızda,% 15,4 idi. Wang ve arkadaşları da Roma III kriterleri ile yaptıkları çalışmalarında sadece dispepsi oranını % 15,2, İBS overlapingi ile birlikte % 20,2 bulmuşlardı. Fonksiyonel barsak bozukluklarının sıklığı % 45,1 bulundu. Bu kadın-erkek, doktoryardımcı sağlık personeli arasında istatistiksel farklılık göstermiyordu. Bunun % 20,6’ sı spesifik olmayan barsak bozukluklarıydı. Fonksiyonel barsak bozukluklarının neredeyse

yarısını oluşturan bu grubu daha iyi tanımlayıcı ya da ayırt edici kriterler düzenlenebilir.

Bizim çalışmamızda İBS oranı % 10,1 idi. Wang’ ın çalışmasında da sadece İBS oranı %

10,9, dispepsi overlapingi ile birlikte % 15,9 hesaplanmıştır. Bu çalışma ülkemizde Roma III kriterleri kullanılarak tüm fonksiyonel gastrointestinal bozuklukların tarandığı ilk çalışmadır.

A REFORMA TRABALHISTA NO BRASIL E NA FRANÇA: mercado de trabalho e desigualdades sociais
Authors: Sousa Antonio Paulino de , Anjos Elisa Maria dos , Nascimento Eloy Natan Silveira , Silva Paulo Cesar Garré
Published: November 2022

O presente artigo objetiva debater sobre o mercado de trabalho na contemporaneidade a partir das reformas trabalhistas realizadas no Brasil e na França, buscando compreender seus efeitos no mercado de trabalho, na garantia dos direitos dos trabalhadores e na produção do Direito do Trabalho. A reforma trabalhista indica que a sociedade está vivendo transformações profundas que destroem as instituições sociais. O que está em jogo é a institucionalização do trabalho sem o Direito do Trabalho e o aumento das desigualdades sociais.  Para tanto, mostra as contradições entre tais reformas e os princípios desenvolvidos em organismos internacionais que orientaram a construção de regulamentações baseados na ótica da dignidade humana. Além disso, analisa os efeitos da reforma trabalhista brasileira na categoria profissional dos bancários.
ОРГАНИЧЕСКОЕ ВЕЩЕСТВО И ГЕОХИМИЯ УГЛЕЙ СРЕДНЕЮРСКОГО ВОЗРАСТА МЕЖЕГЕЙСКОГО МЕСТОРОЖДЕНИЯ (УЛУГ-ХЕМСКИЙ БАССЕЙН, ТЫВА)

Актуальность. Каменные угли Межегейского месторождения используются преимущественно в качестве спекающей основы для производства кокса. Однако неоднородность и многокомпонентность их вещественного состава позволяет рассматривать угли как сырье для глубокой химической переработки и как носитель ценных металлов в различных концентрациях, а угольный пласт – как угольно-газовую залежь. Подобный комплексный подход в освоении горючего ископаемого нуждается в исследованиях с различных позиций особенностей органического и неорганического вещества углей, которые зависят от исходных условий накопления и источников вещества.Цель: изучить состав органического вещества углей пласта Улуг среднеюрского возраста Межегейского месторождения Улуг-Хемского угольного бассейна впервые в комплексе углепетрографических и органогеохимических методов исследования. Методы: углепетрографическое изучение мацерального состава под микроскопом в шлифах в проходящем свете; определение аналитической влажности и зольности стандартизированными методами. В составе геохимических исследований выполнено выделение хлорформенного битумоида из углей, фракционирование полученного экстракта, газово-хроматографический и хромато-масс-спектрометрический анализ алифатической и ароматической фракций битумоида. На основе полученных данных вычислены индексы, характеризующие обстановки накопления органического вещества, его возможные источники и степень термической преобразованности. Результаты проведенных углепетрографических и геохимических исследований углей среднеюрского возраста Межегейского месторождения Улуг-Хемского бассейна показывают, что по микрокомпонентному составу угли практически мономацеральные с преобладанием бесструктурного витринита. Формирование углей происходило на периферии крупного, возможно, периодически связывавшегося с морем озера в условиях, близких к маршевым. Изучен состав и распределение алканов, стеранов и гопанов в алифатической фракции битумоида. Характер распределения н-алканов и изопреноидов свидетельствует об образовании углей преимущественно из остатков водной растительности при некотором участии гумусового вещества. Существенный вклад высшей наземной растительности подтверждается также и распределением стеранов С27, С28, С29. Значения коэффициента нечетности алканов, известные соотношения изомеров стеранов, гопанов и ароматических углеводородов свидетельствуют о высокой зрелости угольного вещества.
