Authors: De Aguiar Mariane Rodrigues Volz , Kocourek Sheila , Oliveira Jairo da Luz , Rodrigues Adriano Correia
Published: September 2020

A ideia de desenvolvimento ganha força ao longo do século XX, a recorrente distinção entre crescimento e desenvolvimento econômico no plano histórico toma sentido a partir do entrelaçamento entre o aumento da produção e renda per capita e, ao mesmo tempo, mudanças profundas na sociedade. O tema de desenvolvimento, com enfoque para além do crescimento econômico, relacionando aspectos de qualidade de vida, sustentabilidade ambiental e equidade social e cultural, vem ganhando destaque nas discussões da área das ciências sociais. A busca por sociedades democraticamente qualificadas, atuando de forma indissociada aos interesses exclusivos da coletividade, sinaliza a necessidade de desenvolver redes de cooperação, baseadas na confiança e colaboração mútuas. Destaca-se a existência de conselhos regionais no sentido de exercer o controle social, mas também a articulação representativa e de desenvolvimento regional. Também as universidades, sobretudo as públicas, têm um compromisso social com o desenvolvimento regional; a propósito, as universidades são vetores indutores de desenvolvimento regional, conectando-se com o mundo ao mesmo tempo que se enraízam regionalmente, com efeitos na produção e no consumo da economia, que repercutem de forma multiplicadora nas estruturas espaciais, sobretudo nas cidades em que estão localizadas. Neste sentido, o estudo em tela teve como objetivo realizar um levantamento de publicações acerca da participação de universidades no processo de desenvolvimento regional, de 2008 a 2016, para analisar em quais óticas a contribuição universitária para o desenvolvimento regional vem sendo estudada. Para isso, utilizou-se a análise bibliométrica, realizada a partir da coleta de dados nas plataformas Scopus e Redalyc. Os resultados mostram que, apesar de o tema ter ganhado certa evidência no último quinquênio, ainda há carência de pesquisas que discutam com profundidade a relação das universidades como desenvolvimento regional.

Published: September 2020

O Programa Bolsa Família (PBF) apresenta diversos efeitos na população com riscos e vulnerabilidades sociais, principalmente em relação à alimentação, educação e saúde. O objetivo foi identificar padrões alimentares de famílias beneficiárias ou não do PBF em município paulista, analisando sua associação com níveis de insegurança alimentar (IA). O estudo incluiu 150 famílias. Aspectos socioeconômicos, demográficos, antropométricos e de consumo alimentar foram avaliados por meio de questionários validados. A IA foi avaliada pela Escala Brasileira de Insegurança Alimentar (EBIA). Os padrões alimentares foram calculados utilizando a análise de Cluster. A associação entre a IA e o PBF com padrões alimentares foi testada utilizando o modelo de regressão de Poisson. Foram identificados três padrões alimentares: restrito, saudável e tradicional. O padrão restrito foi associado com menor escolaridade, histórico de anemia, IA moderada (IAM) ou IA grave (IAG) e maior idade média. Na análise não ajustada e ajustada para idade, as famílias com IAM ou IAG foram, respectivamente, 55% e 57% mais propensas a aderir um padrão restrito e 41% menos propensas a seguir um padrão saudável. Ter um padrão saudável ou tradicional foi relacionado à origem dessa população, revelando um elemento importante dentro do conceito de SAN: a soberania alimentar.
Tackling the Problem of Crops Supply Chain in Indonesia using Internet of Things Based on Law of the Farmers
Authors: Soeparna Intan
Published: September 2020

One of the agricultural problems in Indonesia is the crops supply chain that hampers the ability of the farmers to achieve better income from their farming activities. Although the government has issued the Law of the Farmer No 19 the year 2013 to protect and empower the farmer, the problem is still prevalent. It leads to a question of how to implement the law to tackle the problem of the crops supply chain. The study explains that the government has issued an Economy Digital Policy to create electronic commerce in agribusiness (E-Agribusiness) for farmers and to solve their agribusiness problem. However, the use of electronic agribusiness is not yet ample to solve the problem of the crops supply chain. The solution is a suggestion to apply Internet of Things which is using RFID technology to solve the problem of crops supply chain and distribution in E- Agribusiness. The methodology of the study is the normative approach and literature review.
Penal Mediation in the Criminal Law as a Shift in Social Contract Theory
Authors: Sukandia I Nyoman , Budiartha I Nyoman Putu , Wirawan Ketut Adi
Published: September 2020

Social contract theory is the theory that illustrates the origin of a state formation. The theory of social contracts is composed of several instruments, including natural human rights, morals and mutual agreement (common will). Humans (individuals) surrender their rights to the ruler (state). The rights that are handed over to the state include rights in the field of public law (public interest). One of the rights in the field of public law is the right to establish norms in criminal law (ius poenale) and the right to convict (ius puniendi). Through the existence of penal mediation in Indonesia, the state's right to convict offenders is reduced. It also means that the rights handed over by individuals to the authorities (state) in social contracts are reduced. Its theoretical implication is that the right of the state to impose criminal sanctions on offenders who are based on the surrender of individual rights to social contracts, begins to be purified again with the settlement between individuals through penal mediation on violations of public (criminal) law that take place.

Fracture patterns and mechanical properties of GFRP bars as internal reinforcement in concrete structures
Authors: Canbaz Mehmet , Albayrak Uğur
Published: September 2020

Glass Fiber Reinforced Plastic (GFRP) composites as rolled bars can be used as steel rebar to prevent oxidation or rust which is one of the main reasons concrete structures deteriorate when exposed to chlorides and other harmful chemicals. GFRP is successful alternative for reinforcement with high tensile strength- low strain, corrosion resistance and congenital electromagnetic neutrality in terms of longer service life. The main goal of the study is to investigate the mechanical and bonding properties of GFRP bars and equivalent steel reinforcing bars then compare them. GFRP and steel rebar are embedded in concrete block with three different levels. Mechanical properties of GFRP and steel bars in terms of strength and strains are determined. On the other hand; modulus of elasticity of GFRP and steel bars, modulus of toughness and modulus of resilience were calculated using stress-strain curves, as a result of the experiments. Pull-out tests are conducted on each GFRP and rebar samples which are embedded in concrete for each embedment level and ultimate adherence strengths are determined in terms of bar diameter–development length ratio. Yield strength, strain and modulus of elasticities of GFRP samples are compared to steel rebar. According to the test results reported in this study, GFRP bars are used safely instead of steel bars in terms of mechanical properties.
Design analysis of a steel industrial building with wide openings exposed to fire
Authors: Cirpici Burak Kaan
Published: September 2020

In order to design a fire-resistant steel structure, the change in the physical and mechanical properties of the steel at high temperatures must be known. As the temperature of steel structural elements increases during fire, their strength decreases considerably. After a certain temperature, these strength drops reach critical levels. Therefore, collapses and various deformations (buckling, arching, etc.) occur. To prevent these collapses during the fire, various fire protection materials must be applied to the structural members such as column and beam. Columns are the most critical structural elements in a steel bearing system. While the possible collapse of the columns may cause the collapse of the whole structure, the beams alone may not cause the collapse of the structure, and the column-beam junctions directly affect the spread of fire. Since there will be many openings and gaps in industrial buildings, the spread and growth of a possible fire becomes very serious. Special fire protection measures are therefore required. In this study, the behavior of a steel industrial structure designed and designed under the influence of Standard Fire (ISO 834) was investigated, the distribution of the temperatures in the structural elements was determined, the required fire protection material was selected, and both protected and unprotected steel temperatures were determined. This design against fire is designed to provide fire resistance for 1 hour (60 min) for this structure. During this period, the type and optimum thickness of the protection material to be applied before reaching the critical temperature values for which the strength of the steel material would lose and would be damaged and compared with the temperatures that would occur in the structural elements without applying fire protection. According to the findings of the study, it was concluded that 25 mm drywall box protection material should be applied on the inner columns and 20 mm on the edge columns and 15 mm on the corner columns. In addition to this, it was concluded that spray beams (intumescent coating) of different thicknesses between 15-20 mm were applied to the beams depending on the location and the load to be affected and the type of joint. After these applied passive fire protection materials, the temperatures obtained in the structural elements reached to 500-550 as a result of 1-hour fire design. These temperatures are acceptable temperature values given the strength drop in critical temperature ranges for steel under the 1-hour fire condition.

Authors: Karalar Memduh , Çavuşli Murat
Published: September 2020

Investigation of carrying capacity performance of reinforced concrete (RC) structures is very important for structural engineering. In this study, it is aimed to examine the nonlinear carrying capacity performance of an RC laboratory structure by using three dimensional (3D) modelling approach. For this purpose, Zonguldak Bulent Ecevit University Laboratory Structure is selected and it is modeled as three dimensional by utilizing IDECAD static software. After modelling all beams, columns and floors according to 2018 Turkish earthquake code, concrete classes are determined for all bearing elements and specified concrete classes are defined for all elements of 3D model. Then, structure is analyzed for empty situation (Case 1) and structural performance of building is analyzed to this situation. In the past, a flat of this RC structure has been exposed to strong machine loads. For this reason, a machine which is fixed on the floor is placed in the 3D model and RC structure is analyzed considering nonstructural machine element loads (Case 2). According to analysis results, Case 1 is compared with Case 2 and it is clearly seen that nonstructural machine loads effect nonlinear carrying capacity performance of RC buildings.

Published: September 2020

Critical deflection and stress values of perforated circular plates under loads has an important role on the design criteria. For the perforated circular plates, the basic problem is determining how they have a perforation schema for the most suitable design. For this purpose, 10 different perforated circular plate models were presented and their static analysis was studied. All of the models have the same open area percentage but different number of holes. In this way, it was more convenient to compare the results. The circular plates were analyzed under their self-weight and uniformly distributed load with different nine thickness to diameter ratios obtained based on Classical Plate Theory. In addition, two set of analyses have been performed on the circular plates for fixed supported and simply supported boundary conditions. As an example, for the 6th model critical displacement and stress values under self-weight and under uniformly distributed load are investigated in detail. Designers of perforated circular plates can use the graphics presented in this study. The present study also purposes the shape optimization of thin circular perforated plates with round and staggered holes.

Silver Nanoparticles and their Role in Gene Expression of Motility Gene motB and Repression of AI-2-Controlled Gene
Authors: Mahmood Bassam Shaker
Published: September 2020

Antibiotic resistance is the capability of the strains to resist or protect themselves from the effects of an antibiotic. Such a resistance towards the current antimicrobials leads to the search of novel antimicrobials. Nanotechnology has been promising in different field of science and among it is the use of nanoparticles as antibacterial agents. The gastrointestinal tract seems to be the primary reservoir of uropathogenic E.coli (UPEC) in humans. UPEC strains harbour the urinary tract and cause urinary tract infection. They cause serious ailments in terms of humans. They develop resistance and increase their virulence by forming biofilms. They also show a remarkable locomotory movement with the aid of autoinducer controlled genes (AI-2).

The present study is designed to investigate the expression levels of the AI-2 controlled genes and the motility genes in the presence of nanomaterials. RT PCR amplification together with the antibacterial and motility studies were done to compare the significant effect of silver nanoparticles on the pathogen. S-adenosylmethionine assay was also done to confirm the role of the treatment on the repression of the AI-2 genes.  

The results showed silver nanoparticles have significant effect on the motility studies. The relative expression and repression of motB gene was under the control of AI-2 kinase protein. This confirms the possible role of the nanoparticles towards the pathogen UPEC. There was also an inhibition on the biofilm formation under the effect of the nanoparticle treatment. The study concludes that the silver nanoparticles could be used as a novel antibacterial agent against the UPEC strains and thereby inhibits the antibacterial resistance.

Authors: Aljubouri Ali Abadi , Mohammed Safa hasan , Mohammed Mudhafar ali
Published: September 2020

Sn effect on the phase transformation behavior, microstructure, and micro hardness of equiatomic Ni-Ti shape memory alloy was studied. NiTi and NiTiSn alloys were produced using vacuum induction melting process with alloys composition (50% at. Ni, 50% at.Ti) and (Ni 48% at., Ti 50% at., Sn 2% at.). The characteristics of both alloys were investigated by utilizing Differential Scanning Calorimetry, X- ray Diffraction Analysis, Scanning Electron Microscope, optical microscope and vicker's micro hardness test. The results showed that adding Sn element leads to decrease the phase transformation temperatures evidently. Both alloy samples contain NiTi matrix phase and Ti2Ni secondary phase, but the Ti2Ni phase content decreases with Sn addition and this is one of the reasons that leads to decrease the micro hardness of alloy with adding Sn element in a noticeable manner. The micro hardness decreases from 238.74 for NiTi equiatomic alloy to 202 for NiTiSn alloy after heat treatment.

Published: September 2020

Multiple linear regressions are concerned with studying and analyzing the relationship between the dependent variable and a set of explanatory variables. From this relationship the values of variables are predicted. In this paper the multiple linear regression model and three covariates were studied in the presence of the problem of auto-correlation of errors when the random error distributed the distribution of exponential. Three methods were compared (general least squares, M robust, and Laplace robust method). We have employed the simulation studies and calculated the statistical standard mean squares error with sample sizes (15, 30, 60, 100). Further we applied the best method on the real experiment data representing the varieties of cigarettes according to the US Federal Trade Commission.
Modified BFGS Update (H-Version) Based on the Determinant Property of Inverse of Hessian Matrix for Unconstrained Optimization
Authors: Mahmood Saad Shakir
Published: September 2020

The study presents the modification of the Broyden-Flecher-Goldfarb-Shanno (BFGS) update (H-Version) based on the determinant property of inverse of Hessian matrix (second derivative of the objective function), via updating of the vector s ( the difference between the next solution and the current solution), such that the determinant of the next inverse of Hessian matrix is equal to the determinant of the current inverse of Hessian matrix at every iteration. Moreover, the sequence of inverse of Hessian matrix generated by the method would never  approach a near-singular matrix, such that the program would never break before the minimum value of the objective function is obtained. Moreover, the new modification of BFGS update (H-version) preserves the symmetric property and the positive definite property without any condition.
CTJ: Input-Output Based Relation Combinatorial Testing Strategy Using Jaya Algorithm
Authors: Younis Mohammed Issam , Alsewari Abdul Rahman A. , Khang Ng Yeong , Zamli Kamal Z.
Published: September 2020

Software testing is a vital part of the software development life cycle. In many cases, the system under test has more than one input making the testing efforts for every exhaustive combination impossible (i.e. the time of execution of the test case can be outrageously long). Combinatorial testing offers an alternative to exhaustive testing via considering the interaction of input values for every t-way combination between parameters. Combinatorial testing can be divided into three types which are uniform strength interaction, variable strength interaction and input-output based relation (IOR). IOR combinatorial testing only tests for the important combinations selected by the tester. Most of the researches in combinatorial testing applied the uniform and the variable interaction strength, however, there is still a lack of work addressing IOR. In this paper, a Jaya algorithm is proposed as an optimization algorithm engine to construct a test list based on IOR in the proposed combinatorial test list generator strategy into a tool called CTJ. The result of applying the Jaya algorithm in input-output based combinatorial testing is acceptable since it produces a nearly optimum number of test cases in a satisfactory time range.

Oryza sativa japonica (ofada rice) is largely grown in Aramoko, Abakaliki and Ofada are communities and consumed by both the poor and rich in Nigeria. A total of twenty ofada rice farmlands were identified in each study area and rice samples were randomly collected, thoroughly mixed to make a representative sample from each farmland. Soil samples were collected in each farm to a depth of 5-15cm from at least eight different points and thoroughly mixed together to form a representative sample. The samples were thereafter taken to the laboratory for preparation and spectroscopic analysis. A well-calibrated NaI(Tl) gamma-ray detector was used in spectrometric analysis of the samples and descriptive statistics was used to analyze the results.

The respective mean 40K, 238U and 232Th activity concentrations in the rice were 261.8±52.5Bq/kg, 9.6±1.2Bq/kg and 8.7±1.0Bq/kg (Ofada); 257.3±39.0Bq/kg, 9.3±1.1Bq/kg and 7.8±1.8Bq/kg (Abakaliki); and 248.2±54.8Bq/kg, 9.3±0.9Bq/kg and 7.6±1.5Bq/kg (Aramoko). The respective mean 40K, 238U and 232Th activity concentrations in the soils were 333.9±62.8Bq/kg, 11.1±1.1Bq/kg and 11.0±1.4Bq/kg (Ofada); 306.8±36.0Bq/kg, 10.7±0.8Bq/kg and 9.4±1.8 Bq/kg (Abakaliki) and 321.8±42.4Bq/kg, 10.9±0.5Bq/kg and 9.5±0.6Bq/kg (Aramoko). The highest mean ingestion dose of 106.0±8.0µSv/y and outdoor effective dose of 32.4±3.40µSv/y were recorded in Ofada community. The highest mean ingestion cancer risk of (0.33±0.004) x10-3was recorded in Aramoko. The results indicated significantly lower radionuclide ingestion dose than the world limit value of 290µSv/y and lower cancer risks than the UNSCEAR recommended limit of 0.29x10-3, therefore consumption of ofada rice from the areas may not pose any serious health impact.

Background: Cytotoxic chemotherapy can cure advanced germ cell tumors. Nevertheless, cancer treatment may induce cellular senescence and accelerate molecular aging. The aging process implies an increase of cells expressing p16INK4a and changes in lymphocyte subpopulations. Our aim was to study the potential induction of premature immunosenescence in testicular cancer survivors (TCS) exposed to chemotherapy. Methods: Case-control exploratory study of TCS treated with chemotherapy (³3 BEP cycles, disease-free ³3 months) compared with age matched healthy controls. Peripheral blood mononuclear cells were isolated, and lymphocyte subpopulations were analyzed by flow cytometry. CDKN2A/p16INK4a expression in T cells was measured using qPCR. The percentage of lymphocyte subpopulations and the CDKN2A/p16INK4a expression in TCS were compared with the control group using the Wilcoxon signed-rank test. Results: We included 16 cases and 16 controls. The median age was 27 years (minimum 24, maximum 54) and the median time on surveillance was 26.5 months (minimum 3, maximum192). TCS had a lower percentage of total T cells and CD4+ T cells in total lymphocytes. Among the CD4+ T lymphocytes, TCS had less naïve CD4+ and increased memory CD4+ cells. Within the CD8+ T lymphocytes, TCS exhibited a decrease in the percentage of naïve cells and an increase in CD8+CD45RA+CD57+ cells. TCS also exhibited decreased memory CD19+ B cells compared to the controls. The relative expression of CDKN2A/p16INK4a in T cells was increased in TCS (mean 1.54; 95% CI of the mean: 1.074-2.005; p=0.048).Conclusion: In this exploratory study, TCS showed increased expression of CDKN2A/p16INK4a and a lymphocyte phenotype that has been associated with immunosenescence. Further studies are warranted to define the clinical implications of these alterations in TCS.

Background: Pancreatic and periampullary carcinoma are aggressive tumours where preoperative assessment is challenging. Disseminated tumour cells (DTC) in the bone marrow (BM) are associated with impaired prognosis in a variety of epithelial cancers. In a cohort of patients with presumed resectable pancreatic and periampullary carcinoma, we evaluated the frequency and the potential prognostic impact of the preoperative presence of DTC, defined as cytokeratin-positive cells detected by immunocytochemistry (ICC).Methods: Preoperative BMsamples from 242 patients selected for surgical resection of presumed resectable pancreatic and periampullary carcinoma from 09/2009 to 12/2014, were analysed for presence of CK-positive cells by ICC. The median observation time was 21.5 months. Overall survival (OS) and disease-free survival (DFS) were calculated by Kaplan-Meier and Cox regression analysis.Results: Successful resections of malignant tumours were performed in 179 of the cases, 30 patients resected had benign pancreatic disease based on postoperative histology, and 33 were deemed inoperable intraoperatively due to advanced disease. Overall survival for patients with resected carcinoma was 21.1 months (95% CI: 18.0-24.1), for those with benign disease OS was 101 months (95% CI: 69.4-132) and for those with advanced disease OS was 8.8 months (95% CI: 4.3-13.3). The frequency of CK-positive cells was 6/168 (3.6%) in resected malignant cases, 2/31 (6.5%) in advanced disease and 4/29 (13.8%) in benign disease. The presence of CK-positive cells was not correlated to OS or DFS, neither in the entire cohort nor in the subgroup negative for circulating tumour cells (CTC). Conclusions: The results indicate that CK-positive cells may be present in both patients with malignant and benign diseases of the pancreas. Detection of CK-positive cells was not associated with differences in prognosis for the entire cohort or any of the subgroups analysed.Trial registration: clinicaltrials.gov (NCT01919151)

Published: September 2020

Background: Neonatal thrombocytopenia (NT) (platelet count <150 x 109/L) is a common finding in the neonatal intensive care unit (NICU). The main aim of this study was to assess the prevalence, rick factors, and outcomes of severe NT in full term (FT) infants.Methods: During the study period, all FT infants who met the inclusion criteria for NT on two occasions were included. Maternal data, such as maternal age, weight, gestational age, mode of delivery, and history of systemic diseases, including diabetes mellitus, pre-eclampsia, systemic lupus erythematosus, and immune thrombocytopenic purpura, were recorded. Furthermore, neonatal data, such as gender, neonatal weight, causes/duration of admission, types of respiratory support used, complete blood count measurements, and outcomes for neonates admitted to the NICU, were recorded.Results: In total, 55 FT infants with NT met the inclusion criteria, and 29 (52.73%) cases had severe NT. The most common cause of NT was neonatal sepsis (20 cases, 36.35%), followed by a postoperative state (5 cases, 9.09%). Moreover, in cases of positive blood cultures, the most commonly isolated organism was Escherichia coli (6 cases, 10.90%), followed by Klebsiella (5 cases, 9.09%). Cases of severe NT needed more platelet transfusions (P=0.001) and had higher rates of mortality (P=0.001) when compared to cases of mild/moderate NT associated with signs of bleeding and pulmonary/intraventricular hemorrhage (IVH) (P=0.001).Conclusion: Severe NT occurred in 52.73% of cases. The most common cause of NT was neonatal sepsis, followed by a postoperative state. Furthermore, severe NT, when compared to mild/moderate NT associated with signs of bleeding and pulmonary/IVH, needed more platelet transfusions and had increased mortality.

Background: Percutaneous endoscopic decompression (PED) is considered a minimally invasive and safe procedure in lumbar degenerative disease. Few authors report the success of PED for thoracic spinal stenosis (TSS) with thoracic myelopathy. The objective of this study was to compare the outcome of PED versus posterior decompressive laminectomy (PDL) for TSS.Methods: We retrospectively reviewed 30 consecutive patients who underwent surgery for single-level TOLF from January 1, 2015 to May 1, 2019.These patients were divided into PED (n=16) and PDL(n=14) group. Preoperative demographic characteristics and perioperative outcomes were reviewed. Pre- and postoperative neurological status was evaluated using the modified Japanese Orthopaedic Association (mJOA) score and the recovery rate (RR).Results: The patients’ mean age was 57.3 years (27-76) in PED group and 58.8 years (34-77) in PDL group. No statistical difference was found between two groups with regards to neurological status at pre-operative and final follow-up. The RR in PED group achieved the same improvement as PDL group (87.5% vs 85.7%, P>0.05), while the PED brought advantages in operative time(m) (86.4 vs 132.1, p<0.05), blood loss (mL) (18.21 vs 228.57, p<0.05),drainage volume(mL) (15.5 vs 601.4, p<0.05), hospital stay (d) (3.6 vs 5.6, p<0.05).Conclusions: Both PED and PDL showed favorable outcome in the treatment of TSS. Besides, PED had advantages in reducing traumatization. In terms of perioperative quality of life, PED could be an efficient supplement to traditional posterior decompressive laminectomy in patients with TSS.
