Published: August 2020

Seiring dengan peningkatan pengguna internet, kebutuhan pengalamatan Internet Protocol versi 4(IPv4) semakin meningkat sehingga dikhawatirkan ketersediaannya akan semakin berkurang dan habis. Kehadiran Internet Protocol versi 6 (IPv6) yang merupakan protokol pengalamatan internet generasi terbaru, ditujukan untuk menggantikan penggunaan IPv4 saat ini. Namun, dalam implementasinya masih terdapat beberapa kendala yang salah satunya adalah kondisi infrastruktur yang saat ini yang belum banyak mendukung implementasi IPv6 sehingga proses migrasi IPv4 ke IPv6 menjadi sangat sulit. Pada akhirnya diterapkanlah metode transisi IPv6 untuk melakukan koneksi terhadap infrastruktur IPv4. Teknik 6to4 dan L2TP/IPSec merupakan metode tunneling yang mampu melakukan transisi dari IPv4 ke IPv6. Dalam penelitian ini, dilakukan komparasi terhadap kedua metode tersebut dengan melakukan pengukuran throughput, delay dan packet loss dengan berbagai skenario koneksi jaringan. Berdasarkan hasil dari percobaan yang dilakukan, diketahui bahwa peneraepan teknik L2TP/IPSec menghasilkan kualitas koneksi yang lebih baik daripada kualitas koneksi penerapan teknik 6to4.

Published: August 2020

O texto oferece um preâmbulo sobre os processos de ensino das disciplinas de criação publicitária. Deste modo, será feita uma análise do livro Criatividade em Propaganda, de Roberto Menna Barreto (2004[1978]), autor amplamente utilizado pelos cursos da área. A partir de alguns “entraves naturais”, por vezes, frustrantes ao resultado final das disciplinas, sublinha-se caminhos alternativos ao uso desta bibliografia nos cursos da área. Dessa maneira, a partir de relatos profissionais, aliadas as práticas de ensino desta disciplina, serão apontados desafios no presente, ou mesmo, para o futuro. O objetivo é lançar luz tanto aos docentes, quanto aos alunes[1] que se interessam pela área, chamando atenção as oportunidades, as tensões sociais atuais e as possíveis formas de trabalho fora do ambiente "tradicional” da Criação.

Authors: Zakaria Rosnah , Ali Ab Malik Marwan
Published: August 2020

Solid polymer-based electrolyte materials are a great interest due to their many interesting characteristics such as flexibility and it is easily prepared into films with a large surface area. Two sets of k-carrageenan-methyl cellulose samples were prepared using the solution casting method. Set 1, the wt% of k-Carrageenan was fixed at 0.1 wt%, while methyl cellulose and NH4I was varied. Set 2, the wt% of methyl-cellulose was fixed to 0.1 wt% and the carrageenan and NH4I was varied. The functional group of samples were studied using FTIR spectroscopy and the ionic conductivity were studied using impedance spectroscopy, EIS at room temperature. FTIR spectra from set 1 show a small hump at between the 1500 cm-1 to 1000 cm-1 spectra’s which O=S=O symmetrical vibration from methyl cellulose component. This hump was shifted to higher wavenumber due to the increasing of NH4I wt% in the samples. The second region of set 2’s spectra shows the wavenumber between of 2000 cm-1 to 1500 cm-1 is the deformation of H-O-H band interactions and its wavenumber decreasing as the addition of salts increasing. The third region of spectra between 1500 cm-1 to 1000 cm-1 represents the band of O=S=O symmetrical vibration. This bands shifted to the lower wavenumber due to addition of salts and it became less intense towards salt addition. On the other hand, the best conductivity is 6.00 x 10-8 S cm-1 which belongs to B2 of set 2 with a composition of 0.3 wt% k-carrageenan with 0.1 wt% methylcellulose and 0.6 wt% NH4I salt and the lowest conductivity is 3.19 x 10-9 S cm-1 which its composition is 0.1 wt% k-carrageenan with 0.4 wt% methylcellulose and 0.5 wt% NH4I salt in sample D1 of set 1. As a conclusion, the optimum component by weight percentage of k-carrageenan: methyl cellulose: NH4I is 0.3:0.1:0.6.

Published: August 2020

Non-degradable properties of polyethylene (PE) films due to long-chain structure cause increment of solid waste plastic. Many researchers, with different purposes, have studied the incorporation of functional materials to PE. Studying the impact of incorporation of aloe vera (AV) into PE films in terms of its characteristic and mechanical properties is the main objective of this paper. The films were prepared using melt-blending and hot press technique. The characterization assessed for the PE and PE-AV films were spectroscopy, crystalline phase, thermal analysis and performance of mechanical properties of the sample.  The functional group detected in spectroscopy studied did not show any changes for PE film or PE with the presence of AV. Lower thermal degradation temperature (Td) obtained for PE-AV3 while others film found no significant changes of Td value and only one peak of thermal degradation occurred for all film. The same goes to the analysis obtained from differential scanning calorimetry (DSC) data. However, the crystalline structure displayed momentous peak changes for PE with AV. The highest tensile strength (TS) obtained by PE-AV3, at once developing highest value of Young’s modulus (YM), modulus of resilience (UE) and modulus of toughness (UT). A certain amount of AV has substantial effect on changing the polymeric structure especially improving the mechanical properties of PE film. Therefore, AV has potential to become an additive for developing a new partially degradable PE film.

Published: August 2020

Kenya is one of the many countries in Sub Saharan Africa affected by climate variability and its related hazards due to changes in temperature and variations in rainfall in most parts of the country. The present study has been undertaken to assess the adaptation strategies applied by the small scale farmers in response to climate variability in Nyandarua County. The study has been conducted in central region of Kenya which is relatively humid and good for agricultural production. A total sample size of 300 respondents from five sub counties was used to collect the primary data through the random sampling technique. Descriptive Likert analysis and Inferential binary logit regression was used to assess the factors affecting the willingness to adopt crop insurance to mitigate the risks of variability of climate on crop farming. The results of the study indicate that adoption of crop insurance scored very low in relation to other adaptation strategies. The logit regression model on the other hand revealed that age and marital status was positively significant with willingness to adopt crop insurance while the marginal effects of levels of income and monthly income implied that the likelihood of willingness to adapt crop insurance increased by 1.32 times and 13.3 percent respectively. Based on the study findings, if small scale farmers are well supported to adopt crop insurance, then this adaptation strategy can be among the most effective strategies in Kenya. However, due to low adaptive capacity, more awareness needs to be created on the importance and procedures of obtaining the specific agricultural insurance covers. The study concludes that modern adaptation approaches are important in presence of formal crop insurance policies especially in the rural areas of Kenya.

Published: August 2020

In this work, the electroplating of copper on an aluminum substrate without electrochemical surface treatment was investigated. Electroplating of copper on aluminum substrate was prepared from copper sulfate electrolyte bath with various current densities 1 mA/cm², 3 mA/cm², 10 mA/cm², and 40 mA/cm². The effects of current density on the samples properties were characterized using a different technique. The surface morphology, crystallographic orientation, and corrosion resistance of the Copper film were analyzed using a scanning electron microscope, energy dispersive spectroscopy (SEM-EDS), X-ray diffractometer (XRD), and potentiostat. The samples' surface morphology is changed with different current densities because nucleation is driven by transferring the copper ion rate onto the aluminum substrate. The Cu-10 sample exhibits (111) peak higher and the best corrosion resistance than other samples. Moreover, Cu-1 samples have shifted to positive corrosion voltage (Ecorr) than the other samples.

The objective of the study was to analyze the prevalence of self-medication among users of Basic Health Units in the city of Monte Alegre – Rio Grande do Norte State, Brazil. A descriptive exploratory study was carried out, through the application of structured questionnaires, with 125 people. It was observed that 83% of the interviewees practiced self-medication, of these, 34%, they did it monthly. The main justifications for this practice were: difficulty accessing health services (50%), financial reasons (28%) and lack of time (22%). The most used drugs were: analgesic (63%), anti-inflammatory (13%) and sedative / hypnotic (7.0%). Most (55%) claimed to have no or little knowledge about the meaning of self-medication. This demonstrates the need for health education actions in order to educate the population about the risks of this practice, since it can lead to masking of symptoms of diseases, drug interactions and intoxications that compromise the health of the user.

Authors: Sulym Heorhiy , Mikulich Olena , Shvabyuk Vasyl’
Published: August 2020

The influence of impulse load applied for different duration on the distribution of normalised dynamic radial stresses in positive and negative Poisson’s ratio medium was investigated in this study. For solving the non-stationary problem in the case of plane deformation for structurally inhomogeneous materials, the model of Cosserat continuum was applied. This model enables accounting for the influence of shear-rotation deformation of micro-particles of the medium. In the framework of Cosserat elasticity, on applying the Fourier transforms for time variable and developing the boundary integral equation method, solving of the non-stationary problem reduces to the system of singular integral equations, where the components that determine the influence of shear-rotation deformations are selected. The numerical calculations were performed for the foam medium with positive and negative Poisson’s ratio for different values of time duration of impulse. Developed approach can be used to predict the mechanical behaviour of foam auxetic materials obtained at different values of a volumetric compression ratio under the action of time variable load based on analysis of the distribution of radial stresses in foam medium.

The aim of the study is to analyse the main clinical and paraclinical characteristics of elderly patients with left colon cancer. 171 patients with left colon cancer were included in a retrospective study, analysing the differences between the patients under and those over 70 years from the point of view of the symptomatology, laboratory investigations, treatment of anemia, postoperative complications. Secondary anemia is seen in a quarter of the patients, and the indication of intraoperative transfusion was most frequent in the elderly (p=0.007). The incidence of intestinal occlusion increases with age, so that one third of the patients over 80 years are admitted with intestinal occlusion. The management of the elderly patient with left colon cancer should benefit from a pluridisciplinary approach, in the context of the numerous associated disorders and the particularities of the geriatric patient.

Published: August 2020

Nursing theories have been developed to provide guidance in clinical practice, so their knowledge by nurses is mandatory in order to provide advanced nursing care. This paper presents the relationships between the concepts and major assumptions of Henderson’s model and Orem’s theory and then their comparative analysis. Both, Henderson’s model and Orem’s theory of self-care deficit have a major impact, internationally, in education and research, but also in nursing practice, as a result of which their knowledge can open a new perspective on care, especially in countries where they are not well enough known.

In the present study, we aimed at evaluating the relationship between the cognitive coping strategies of people with thyroid diseases and the level of stress experienced by them. During the present study we evaluated the coping strategies with Cognitive Emotion Regulation Questionnaire, and the level of stress experienced by them with Holmes and Rahe stress scale. All patients attended an endocrinology outpatient clinic between may-august 2019. 42 thyroid patients (31 with hypothyroidism and 11 with hyperthyroidism), aged 33-69 were selected for this study. The coping strategies used predominantly by thyroid patients are: rumination, positive reappraisal, catastrophizing. The rumination and the level of stress experienced correlated positively. 295 *, p = .044, statistically significant (p<0.05). 58.13% of patients presented stressful events in the year prior onset of thyroid pathology. This finding is important because restructuring less proactive coping strategies through psychotherapies can be an effective alternative or adjuvant way of treating thyroid diseases.

Aortic valve replacement is a safe therapy that can reverse cardiac remodeling and increase cardiac contractility, improve symptoms and quality of life. We presented a case of a 35-year-old male patient admitted to the Emergency Institute for Cardiovascular Disease and Transplantation of Târgu Mureș, Romania, due to severe aortic stenosis with severely depressed ejection fraction, left atrial myxome and a history of deep vein thrombosis and pulmonary thromboembolism. He underwent excision of the aortic valve and replacement with a mechanical prosthesis, excision of left atrial myxoma and tricuspid annuloplasty. The postoperative evolution was favourable with a significant recovery of the left ventricular systolic function and regression of cardiac symptomatology. This case was particular due to the rapid progression of the aortic pathology with the reduction of cardiac (systolic) function in a relatively short time as well as the occurrence of the thromboembolic event unrelated to the left atrial myxoma and rather associated with the background of cardiac failure with low cardiac output.

Pelvic masses are commonly diagnosed following clinical examination. These may be located in the genital organs or may interest other pelvic and abdominal organs. The pathology of the pelvic masses varies with age. The postmenopausal period is most commonly associated with malignant pathology while reproductive age is associated with benign pathology. The purpose of this paper is to present the experience of the Obstetrics and Gynaecology Clinic of the Sibiu County Clinical Emergency Hospital in laparoscopic myomectomy. We evaluated the patients admitted to the Obstetrics and Gynaecology Clinic of the Emergency County Clinical Hospital in Sibiu who underwent a laparoscopic myomectomy between 1.01.2015 - 06.06.2019. During this time, 14 laparoscopic myomectomies were performed in our clinic. Patients ranged in age from 29 to 57 years.

Published: August 2020

Calcium hydroxide is a slow-acting antiseptic substance used in several forms for the last century in various fields of dentistry. Its applications in endodontics are by far the most meaningful including the treatment of root resorptions and perforations, inducing the apexification process, and most importantly as intracanal medicaments representing a crucial step in the nonsurgical management of large periapical lesions. The aim of this article is to conduct a review of the properties, antimicrobial effect, combination with adjuvant substances, biocompatibility, cytotoxicity, and adverse effects of calcium hydroxide-based dressings as an additional manoeuvre in the conservative treatment of chronic apical periodontitis and to draw attention on the importance of this extra step.

Two short-term (24 h and 48 h) microcosm experiments using natural waters from three eutrophic lakes (Masurian Lake District, Poland) were performed to assess the impact of eukaryotic inhibitors (a combination of cycloheximide and colchicine) on the abundance of nanoflagellates and small ciliates in the <15 µm fraction. The results showed that eukaryotic inhibitors were not completely effective against either group of protists; however, they reduced their numbers considerably. At 24 h of the experiment, 41, 15, and 7% of nanoflagellate and 48, 23, and 3% of ciliate abundances were not lysed, depending on the lake from which water was taken. However, after 48 h of incubation, only below 7% of nanoflagellates and 33, 40, and 17% of ciliates were present in the treatments with inhibitors. Our results suggest that inhibitors may indirectly change bacterial growth and activity, but they do not definitively inhibit these processes. It was concluded that eukaryotic inhibitors are more effective against small nanoflagellates than larger nanoflagellates and ciliates. Concentrations of inhibitors higher than 200 and 100 mg l−1 for cycloheximide and colchicine, respectively, and an incubation time longer than 24 h also seemed to be more appropriate to achieve the complete inhibition of protists.
Effective Pre-Treatments for Enhancement of Biodegradation of Agricultural Lignocellulosic Wastes in Anaerobic Digestion – A Review
Authors: Rahimi-Ajdadi Fatemeh , Esmaili Masoomeh
Published: August 2020

Agricultural crop residues like stems, straws and leaves are valuable resources for biofuel production, especially methane, due to anaerobic digestion. Biogas from agricultural lignocellulosic wastes is capable of attaining sustainable energy yields without environmental pollution. Farmers in many developing countries burn these wastes throughout their fields, imposing environmental hazard due to emission of greenhouse gases. The main problem in this field is the recalcitrance of the agricultural lignocellulose waste that limits its enzymatic degradation and hydrolysis efficiency and consequently decreases biogas production. Therefore, efficient pre-treatments prior to anaerobic digestion are essential. Various pre-treatment methods are used for increasing the anaerobic digestibility of lignocellulose biomass, such as physical (mechanical, thermal, etc.), chemical, biological and combined pre-treatments. This paper reviews different pre-treatments used in anaerobic digestion for the agricultural lignocellulosic wastes and explains the advantages and disadvantages of each. The most frequently used pre-treatments for main agricultural wastes in process of biogas production are also introduced.

Chronic lymphocytic leukemia (CLL) is a neoplasm characterized by excessive accumulation of B lymphocytes in the peripheral blood, bone marrow and lymph nodes. We assessed the expressions of 22 genes in the p53 pathway in 30 CLL patients and 15 healthy subjects by a RT2 Profiler PCR (polymerase chain reaction) Array technique and their relation to cytogenetic aberrations detected by fluorescent in situ hybridization (FISH). Our Student’s t-test results indicated that ATM, ATR, BAX, CASP9, CDK4, CDKN2A, CHEK1, CHEK2, E2F3, MCL1, MDM2, MDM4, PCNA, RB1, P53 and BCL2 genes were statistically significant (p <0.001). For six genes (APAF1, CDKN1A, E2F1, GADD45A, PTEN and PTX3) were not statistically significant. The ATM, ATR, BAX, CASP9, CDK4, CDKN1A, CDKN2A, CHEK1, CHEK2, MDM2, MDM4, PCNA, RB1, P53, E2F1, GADD45A and BCL2 genes were found to be upregulated by the 2-ᐃᐃCt (relative fold change in gene expression) method. The highest up-regulation was detected in CDKN2A and BCL2 genes, 10.22- and 8.51-fold, respectively. On the other hand, the PTX3 gene with a fold regulation of 1.84 was found to the highest downregulation. Overall, the CDNK2A BCL2 and PTX3 genes are related to the mechanism of the disease in the p53 pathway and may be an important predictor of the prognosis of the disease. The BCL2 gene may be associated with increased risk of developing CLL. We suggest that the PTX3 gene may be considered as a marker associated with CLL disease. The CDKN2A gene expression seems to play a protective role in CLL.

Kabuki syndrome (KS) is characterized by typical facial features and patients are also affected by multiple congenital anomalies, of which congenital heart anomalies (CHAs) are present in 28.0 to 80.0%. In approximately 75.0% of patients, the genetic causes of KS are caused by mutation in the KMT2D gene. Although KS is a well-characterized syndrome, reaching the diagnosis in neonates is still challenging. Namely, newborns usually display mild facial features; therefore the diagnosis is mainly based on congenital malformations. In our case, a newborn was referred for next generation sequencing (NGS) testing due to the prenatally observed CHA. After birth, a ventricular septal defect (VSD), vesicoureteral reflux, muscular hypotonia, cleft palate, mild microcephaly, and some dysmorphic features, were noted. The NGS analysis was performed on the proband’s genomic DNA using the TruSight One Sequencing Panel, which enriches exons of 4813 genes with clinical relevance to the disease. After variant calling, NGS data analysis was predominantly focused on rare variants in genes involved in VSD, microcephaly, and muscular hypotonia; features observed predominantly in our proband. With the aforementioned protocol, we were able to determine the previously unreported de novo frameshift deletion in the KMT2D gene resulting in translation termination. Although our proband is a typical representative of KS, his diagnosis was reached only after NGS analysis. Our proband thus represents the importance of genotypephenotype driven NGS analysis in diagnosis of patients with congenital anomalies.
