Authors: Oktadinata Herry , Putra Adi Ganda
Published: April 2020

Dissimilar metal welds between austenitic stainless steel and carbon steel are commonly used in oil and gas industries for certain reasons. The objective of this research is to asses the effect of filler metal and shielding gas on the microstructure and hardness of dissimilar lap joint of type 304 austenitic stainless steel to JIS SS400 low carbon steel. For the purpose of this investigation, the weldments were produced using flux-cored arc welding (FCAW). Three types of filler metals (E316L, E309L and E308L) and two different gas compositions (100%CO2 and 90%Ar+10%CO2) were selected to be used. Each of the weldments were analyzed on the microstructure characteristic and hardness profile of base metal (BM), heat affected zone (HAZ) and weld metal (WM) using optical microscope and microhardness Vickers. The metallographic examination revealed HAZ-SS400 contains martensites. Both HAZ-304 and WM show austenitic microstructure, with columnar and cellular sub-structures present at WM. The hardness profile of HAZ-304 is higher than BM-304, it may be attributed to the presence of the fine grains in HAZ-304 due to high temperature during welding. The hardness profile of WM-E309L exhibited the hardness from HAZ to WM tend to decrease linearly, while WM-E316L and WM-E308L showed the hardness from HAZ to WM also decreased but drastically dropped at fusion line (FL). The welds using E309L offer the best result in the point of view homogeneity of the hardness profile.

Authors: Nguyen Nam Phuong , Bui Nam Huu , Do Duong Quang
Published: April 2020

In the pharmaceutical market, all products have a life cycle Out of date products should be replaced by new ones, which have better quality. For this reason, modelling and optimizing formulation are the regular demands. Traditional methods of design and optimization - such as statistics, simplex – can only be used for simple and linear data. In case of complicated or non-linear data, alternative methods that are able to deal with such data are needed. This paper presents a solution for optimizing controlled release product formulation using a combination of AI techniques (Soft-Computing): neural networks, fuzzy logic and genetic algorithms. This achievement will help to significantly reduce time and labour in R&D process thank to its good accuracy and high processing speed. The results obtained from this research indicate that the alternative approach can be considered as an effective and efficient method for modelling and optimising controlled release formulations.

Authors: Nguyen Nam Thanh , Vo Cuong Van , Le Dien Khanh , Le Sy Van
Published: April 2020

The question of compensating for the error of dimension due to springback phenomenon when forming metal sheet by SPIF method is being one of the challenges that the researchers of SPIF in the world trying to solve. This paper is only a recommendation that is based on the macro analysis of a sheet metal forming model when machining by SPIF method for calculating a reasonable recompensated feeding that almost all researchers have not been interested in yet: - Considering the metal sheet workpiece is elasto-plastic and the sphere tool tip is elastic, the authors attempt to calculate for compensating the error of dimension due to elastic deforming of the tool tip. - The metal sheet is clamped by a cantilever joint that has an evident sinking at the machiningarea that is also calculated to add to the compensating feeding value. The paper also studies the limited force for ensuring the elastic deforming at these working area of the sheet to eliminate all theunexpected plastic deforming of the sheet. With two small but novel contributions, this study can help to take theoretical model for elastic forming of metal sheet closer to real situation.

Authors: Lê Hân Khả , Nguyễn Nghĩa Hiếu , Nguyễn Oanh Cao Kiều , Nguyễn Nhân Trí
Published: April 2020

Introduction: Fibroblast growth factor-2 (FGF-2) is a multifunctional protein that plays an important role in the regulation of proliferation, differentiation and migration of a variety of cells. The recombinant human FGF-2 (rhFGF-2) is currently used in stem cell culture, medicine and cosmetic products. In this study, we aim to produce secreted rhFGF-2 protein from a Pichia pastoris strain containing multiple copies of the fgf-2 gene to eliminate the disadvantages of intracellular expression systems.

Methods: The recombinant Pichia pastoris carrying the fgf-2 gene was cloned by using homologous cloning method. The recombinant strains were screened by PCR reactions using specific primers for the target gene and the AOX1 promoter sequence. Moreover, the copy number of the fgf-2 gene inserted into the P. pastoris genome was identified by semi-quantitative PCR method. The secreted rhFGF-2 protein was collected in the induced BMMY medium at a final methanol concentration of 0.5%, and purified by one-step heparin affinity chromatography. The quantity and biological activity of the purified protein were determined by competitive ELISA method and MTT assay on NIH-3T3 cell line, respectively.

Results: Various recombinant P. pastoris clones carrying different copy numbers of the fgf-2 gene were obtained and categorized into 3 groups: the low copy strains (4-5 copies), medium copy strains (8-11 copies), and high copy strains (more than 20 copies). Among those strains, the 4-copy one produced the rhFGF-2 protein at the highest expression level. After purification, the purity of rhFGF-2 protein reached 98.8%, and the recovery yield was 179.2 µg of protein from 200 mL of flask culture (equivalent to 850 µg/L). The purified rhFGF-2 protein showed similar biological activity on NIH-3T3 cell line with the commercial FGF-2 protein.

Conclusion: The recombinant FGF-2 protein was successfully secretory expressed from Pichia pastoris, and successfully purified by only one-step chromatography.

Introdução: O Papilomavírus Humano (HPV) e um agente epiteliotrópico que apresenta mais de 100 genótipos. Destes, alguns são considerados de alto risco devido ao potencial para induzir o surgimento de lesões malignas, como o carcinoma cervical, cujo percentual de associação com o referido vírus e de aproximadamente 90%. Nas células infectadas, duas proteínas virais desempenham papel fundamental na tumorigênese. Objetivo: Realizar uma revisão dos trabalhos existentes na literatura cientifica internacional com enfoque no papel das proteínas virais do HPV na carcinogênese. Método: Os artigos utilizados para a realização da presente revisão foram selecionados e obtidos na integra nos portais eletrônicos PubMed e Periódicos Capes. Os descritores utilizados na busca incluíram: Human Papillomavirus, HPV, viral proteins, E5, E6 e E7. Resultados: As proteínas virais E6 e E7 são amplamente conhecidas por promoverem a degradação das proteínas celulares p53 e pRb, respectivamente, efeito que responde por grande parte do potencial ontogênico dos genótipos de alto risco de HPV, sendo funcionalmente equivalentes a mutações dos referidos genes celulares, que são comumente observadas em diversos tumores. Contudo, novos estudos tem demonstrado que essas proteínas virais também estão envolvidas em diversas outras vias tumorais, denotando novamente a relevância das mesmas nesse processo. Ademais, alguns trabalhos apontam a proteína E5 como coadjuvante na carcinogênese. Conclusão: Os diversos efeitos constatados das proteínas precoces virais culminam no favorecimento da proliferação celular descontrolada, imortalização, regulação da diferenciação celular, suscetibilidade a metástase e escape da vigilância imunológica.

Tujuan: Penelitian ini bertujuan untuk mengetahui pengaruh pemberian kanamisin pada pasien tuberkulosis multi drug resistance (TB MDR) terhadap munculnya ototoksik dengan pemeriksaan audiometri. Metode: Penelitian observasional longitudinal dengan pendekatan cohort ini mengevaluasi fungsi pendengaran sebelum dan setelah pemberian kanamisin pada pasien TB MDR. Pemeriksaan fungsi pendengaran menggunakan audiometri nada murni. Kanamisin adalah aminoglikosida pilihan pada pasien dengan TB MDR yang akan diberikan secara injeksi intramuskular. Hasil: Uji Friedman’s menunjukkan ditemukan perubahan yang bermakna pada hasil pengukuran audiometri pada frekuensi tinggi antara pasca injeksi kanamisin bulan pertama, kedua, hingga kelima dengan hasil pengukuran sebelum terapi (p>0,05). Diagnosis ototoksisitas menggunakan kriteria American-Speech-Language-Hearing-Association (ASHA) dapat dideteksi sejak bulan pertama pemberian kanamisin (25%). Kesimpulan: Ada hubungan antara kejadian ototoksik dengan pemberian kanamisin pada penderita TB MDR. Telah terjadi ototoksisitas sejak injeksi kanamisin bulan pertama yang dideteksi dengan menggunakan pemeriksaan audiometri, dan bermakna secara statistik. Introduction: Ototoxicity is one of common side effects of kanamycin which is hard to avoid. Ototoxicity can be detected by a progressive and irreversible high frequency sensorineural hearing loss that can further affect low frequency if the therapy is continued. Kanamycin is the drug-of-choice  for TB MDR through intramuscular (IM)  injection. Purpose: This study aims to determine whether kanamycin can cause ototoxicity in patient with MDR TB  by using audiometry examination. Method: An observational longitudinal study with cohort design, evaluating patient’s hearing threshold before and after kanamycin IM injection once per month using pure tone audiometry. Result: A significant alteration in high pitch before and after injection of kanamycin was revealed with Friedman’s test (p<0.05) for hearing threshold using pure tone audiometry. Furthermore, using American Speech-Language-Hearing Association (ASHA) the diagnosis of ototoxicity can be established since the first month of kanamycin injection in 25% of the subjects, and also 25% in the second month of injection. Conclusion: There is a significant connection between ototoxicity with kanamycin injection in MDR TB patients, statistically proven.  The ototoxicity can happen since the first month of injection, which can be detected using pure tone audiometry.

Authors: González Ramírez Juan Manuel , Onieva Giménez Luis
Published: April 2020

El fenómeno de la globalización ha modificado los códigos de conducta de muchos de los actores que operan en la escena mundial. Entre estos, los responsables de los gobiernos locales han visto cómo han tenido que reforzar sus estrategias de desarrollo económico, tecnológico o social para conseguir posicionar su área de influencia en una buena situación en el ranking competitivo global. Se compite a escala mundial pero las estructuras de gobierno, la generación de conocimiento, el poder de influencia sobre las decisiones ciudadanas ocurren a nivel local. Sin embargo, en este nuevo escenario, los responsables de gobiernos locales se han visto, de forma generalizada, incapaces de dar la respuesta adecuada que el nuevo marco exige, carentes de las competencias suficientes para llevar este reto a buen término. Por ello, es oportuno dotar a los gobiernos locales de herramientas capaces de ayudar en el proceso de diseño de políticas de innovación, de manera que los agentes encargados de vertebrar el liderazgo del territorio en el panorama mundial puedan hacerlo con las mayores garantías de éxito. En el presente artículo se propone una aplicación de la metodología de análisis del valor y del análisis funcional como fórmula eficaz para alcanzar el objetivo reseñado.
Reflexiones sobre la investigación contable en Colombia.
Authors: Castaño Ríos Carlos Eduardo
Published: April 2020

La investigación contable colombiana ha sido un tema de interés desde sus inicios en la década de los años 70 y hoy la gran inquietud que surge es sobre el impacto que ha tenido el desarrollo en una comunidad de investigación y en el contexto internacional. Un barrido por las distintas publicaciones nacionales que aglutinan una buena parte de la producción de investigadores colombianos en contabilidad, deja en evidencia que aún existen limitaciones que no han permitido que se consolide como la ausencia de debate entre colegas, la falta de apoyo institucional, la poca cercanía con la realidad empresarial, entre otras. Bajo ese panorama, se proponen algunas ideas de acercamiento para trabajo en red y fortalecimiento de capacidades en investigación, que de llevarse a cabo, podrían potenciar de manera importante al país, en un escenario de visibilidad internacional.

Abstract

The determination of protein in urine is important in clinical examination along with other parameters in urine. The presence of protein in urine can be interpreted that there is a disorder in kidney. Acid and heat coagulations method is still widely used in many areas to determine protein in urine. In this method, the characteristic of protein that will precipitate in the presence of acid or if exposed to heat is deployed to gain information about the amount of protein. The greater amount of protein, the more prominence is the coagulation. Urine pH also varies according to the condition, classic acidosis will give an acidic urine and the presence of ammonium producing bacteria can cause basic urine. In this research acetic acid method with 6% of CH3COOH and pH value of 2,9 and buffer acetic with pH 4,5 are used to determine the certain amount of protein (+3 value, corresponds with 2-4 mg/dL protein in urine) in varied pH values of urine samples. To compare the results, first in control urine with pH 6,8 the results of both methods is compared and shows no significant different, then the Kruskall-Wallis test is used to compare the results in other pH values to control and the test is shown also there are no significant difference. This shows that either acetic acid at pH 2,9 or acetic buffer at pH 4,5 can be used to determine protein amount in urine.

The studies analysing the use of natural ingredients as an alternative treatment in the field of pharmacology are developing very rapidly. One of researches that is quite promising in the pharmaceutical industry is the application of marine materials. Marine materials that are frequently used consist of shellfish, algae, sponges and seagrass. Several studies on toxicity tests have shown that the methanol extract of seagrass (from species Enhalus acoroides) is more toxic than the other seagrass family. This study aims to test the toxicity level of Seagrass (E. acoroides) extract from Soropia coastal waters. The research method in this study was an experimental laboratory using E. acoroides Seagrass as a sample that was obtained from Soropia Coast, Konawe Regency, Southeast Sulawesi Province. The sample was extracted using methanol as a solvent by macerating it and was tested for its toxicity using the Brine Shrimp Lethality Test (BSLT) method. Toxicity test results showed that the samples with a concentration of 10 ppm, 100 ppm and 1000 ppm in leaves extracts produced an LC50 value of 404.88 ppm, while the stem and root extracts has a value of LC50 >1000 ppm. The test was continued with higher concentration of leaves extracts consisted of 250 ppm, 500 ppm, and 1000 ppm. The toxicity test showed an LC50 value of 0.7309; which means that it was very toxic. The methanol extract of Seagrass (E. Acoroides) is potential to be used for further analysis and anticancer formulations.

Pregnant women with high blood lead posed high risk to their fetus as placental transfer can occurs to the fetus. The objective of this study was to identify the relationship between blood lead and the neuropsychological score of women who were in their 3rd trimester of pregnancy. These respondents were undergoing a routine antenatal checkup at a teaching hospital located in Klang Valley areas.  Blood lead concentrations were analyzed using graphite furnace Atomic Absorption Spectrophotometer (AAS). The neuropsychological scores were measured with WHO Neurobehavioral Core Test battery (NCTB). The test consists of 7 items, which made up of the Digit Symbol, Trail Making, Digit Span, Benton Visual Retention Test, Pursuit Aiming, Santa Ana Manual Dexterity, Reaction Time and Movement Time tests. The mean blood lead was 7.78±4.77 µg/dL. The mean score for the total NCTB test was 50.00±5.24. Statistical analysis showed blood lead concentrations were inversely correlated with the total NCTB score (r= –0.462, p≤0.01). The correlation was about 21.3%. The General Linear Model (GLM) showed that age (β= –0.15, p=0.017), weight (β=2.67, p=0.05) and height (β=–1.97, p=0.05) also influence the total neuropsychological scores. In conclusion, blood lead reduces the total neuropsychological scores. The scores for each of the 7 items were inversely and significantly correlated with blood lead concentrations except for the Trail Making and Santa Ana Manual Dexterity tests.

Published: April 2020

Introduction

There is a broad evidence base to support advanced life support (ALS) education for healthcare professionals being structured, realistic and inclusive of a range of human factors. This paper outlines a curriculum for ALS resuscitation education for providers working in the pre-hospital or resource-limited settings. The focus on pre-hospital ALS education is important because actions taken by pre-hospital healthcare professionals have a critical impact on the likelihood of patient survival.

Methods

The pre-hospital ALS curriculum developed in this research was derived from a survey and interviews with pre-hospital healthcare professionals and first responders, and input from resuscitation, medical and education experts. Following completion of the interviews an expert panel of resuscitation experts was consulted.

Results

Information collected indicated that a pre-hospital ALS course should follow current recommendations of the Australian Resuscitation Council and that the course should be delivered in a mixed mode comprising of online pre-reading and a quiz followed by one day of face-to-face teaching. Equipment should reflect that used in the pre-hospital environment and a pre-hospital ALS course should include scenarios relevant to the pre-hospital setting involving varying numbers of interprofessional healthcare teams as well as first responders and lay persons. Candidates should be assessed on a continual basis and certificates of participation be valid for 2 to 3 years.

Conclusion

To improve pre-hospital resuscitation education and maximise the likelihood of patient survival, ALS education for pre-hospital providers should follow Australian Resuscitation Council guidelines, include pre-course reading, case studies and practical simulation in situations that are likely to be encountered by pre-hospital professionals.

Kesehatan merupakan bagian terpenting bagi kita dimana pengaruh atau datangnya penyakit melalui pola makan, terlebih bagi kita yang memiliki kesibukan yang luar biasa padatnya tentu saja tidak ada waktu untuk sarapan dan lebih memilih makanan cepat saji yang tersedia banyak di kantin atau kafe. Hal ini bukan berarti makanan cepat saji tidak sehat, hal ini akan menjadi masalah jika terlalu berlebih dan tidak memperhatikan takaran saji atau kandungan nutrisi yang ada pada makanan tersebut. Beberapa cara bisa dilakukan dengan menjaga sikap  pola makan misalkan dengan diet atau menggunakan aplikasi perhitungan nutrisi yang ada di pasaran dan gratis untuk diunduh. Jenis aplikasi ini masih kurang efektif dimana aplikasi tersebut masih merupakan perkiraan saja dan tidak bisa digunakan secara realtime.

Penelitian sebelumnya bisa menggunakan teknik computer vision dengan menggunakan image sebagai alat pembaca dari makanan yang akan kita santap. Aplikasi tersebut mampu membaca kandungan nutrisi sekaligus  harga makanan, teknik pengolah image yang digunakan menggunakan metode Deep Learning Neural Network, algoritma ini terbukti memiliki akurasi dan pembacaan data yang tinggi dibandingkan algoritma yang lain. Aplikasi dengan Neural Network yang berbasis image bisa diimplementasikan pada mesin kasir di kantin atau cafe dan bisa dibuat dalam bentuk perangkat mobile sehingga lebih mudah digunakan.

Teknik komputerisasi dengan Deep Learning Neural Network terbukti bisa diterapkan di kantin dan caf

Organizations currently need to conduct an analysis of their business processes in order to improve business performance and productivity. In addition, this analysis can be a way to compete with competitors. However, the analysis of this business process if done manually requires considerable time. Process mining is a technique that helps solve this problem. Information systems that are owned by a company certainly store their every business activity. This data can be processed to find business processes that occur. This data is usually called an event log. Event logs help organizations to find gaps between business processes that occur with those expected. Based on this gap business processes can later be evaluated for later improvement.
