Sidik, Waleed S.,Canakci, Hanifi,Kilic, Ibrahim H.,Celik, Fatih Techno-Press 2014 Geomechanics & engineering Vol.7 No.6

In past few years, the use of bacterial calcium carbonate precipitation (biocementation) has become popular as a ground improvement technique for sandy soil. However, this technique was not applied to organic soil. This study focused on bacterial calcium carbonate precipitation and its effect on permeability in organic soil. A special injection system was prepared for inducing bacterial solution to the samples. The bacterial solution supplied to the samples by gravity for 4 days in specific molds designed for this work. Calcite precipitation was observed by monitoring pH value and measuring amount of calcium carbonate. Change in the permeability was measured before and after biocementation. The test results showed that the pH values indicates that the treatment medium is appropriate for calcite precipitation, and amount of precipitated calcium carbonate in organic soil increased about 20% from untreated one. It was also found that the biocementation can be considered as an effective method for reducing permeability of organic soil. The results were supported by Scanning electron microscopy (SEM) analysis and energy-dispersive x-ray (EDX) analysis.

Sidik, Umar,Lee, Hee Young,Lee, Jai-Yeoul American Scientific Publishers 2015 Journal of nanoscience and nanotechnology Vol.15 No.7

<P>2 at% Mg doped thin films of delafossite CuCrO2 and Cr-deficient CuCr0.97O2 were prepared by pulsed laser deposition. The films were grown on c-sapphire single crystal substrates at a range of substrate temperatures, and the effects of the processing parameters on thin film properties were examined. The crystallinity improved with increasing substrate temperature and Mg-doping. The substitution of Mg in the CuCrO2 and Cr-deficient CuCr0.97O2 thin films increased the electrical conductivity significantly with a slight decrease in optical transmittance. By introducing Mg-doping to Cr-deficient CuCr0.97O2 thin films, a CuCr0.95Mg0.02O2 thin film with an electrical conductivity of 29.63 S/cm and a mean optical transmittance of 60% was fabricated.</P>

Usefulness of intraoperative real-time three-dimensional transesophageal echocardiography in preprocedural evaluation of cortriatriatum -a case report-

Hanafi Bin Sidik,박정민,Yea-Ji Lee,김주덕,Woon-Seok Kang,김성협,윤태균,김태엽,Jae-Gyun Shin 대한마취통증의학회 2013 Korean Journal of Anesthesiology Vol.65 No.6

Cortriatriatum is a rare congenital cardiac disorder with fibromuscular band (diaphragm) dividing the left atrium (LA) into the proximal and distal parts. Surgical correction of cortriatriatum requires full preoperative evaluation of the structural anomalies including the LA diaphragm and their pathophysiology. In the present case, a 44 year-old lady diagnosed as cortriatriatum underwent surgical correction. Intraoperative three-dimensional transesophageal echocardiography provided detailed information regarding the shape and extent of the LA diaphragm, which had been partially evaluated by preoperative two-dimensional transthoracic and transesophageal echocardiography, and facilitated the intraoperative patient management and surgical decision making.

An important aspect of indigenous medicine is the ability of traditional societis to manipulate the environment for their own benefit, for example for their health care. In Indonesia, this indigenous medicine is called jamu.<br/> Jamu mostly consists of a mixture of herbals of the genus Curcuma, Zingiberaceae. There are 19 species of curcuma grown in Indonesia. Eleven of them are popular in the jamu preparations. Ethnopharmacological surveys have shown that 50% of these species are used for post partum protection, dismenorrhea, 30% are used for the treatment of stomache and as cosmetics, 20% for the treatment of various diseases such as fever, worms, asthma, etc. Chemical studies show that they contain curcuminoids, volatile oils, flavonoids, starch, and resinous substance.<br/> Pharmacological studies of extracts and isolated bioactive compounds have shown that they have a broad pharmacological activity such as antibacterial, antifungal, anti-inflammatory, choleretic, antihepatotoxic, antitumor, antioxidant, and antihyperlipidemic activity.

CYP1A1 MspI Polymorphism and Cervical Carcinoma Risk in the Multi-Ethnic Population of Malaysia: a Case-Control Study

Tan, Yee Hock,Sidik, Shiran Mohd,Husain, Sharifah Noor Akmal Syed,Lye, Munn Sann,Chong, Pei Pei Asian Pacific Journal of Cancer Prevention 2016 Asian Pacific journal of cancer prevention Vol.17 No.1

Background: Tobacco smoking is considered a risk factor for cervical cancer development due to the presence of tobacco based carcinogenic metabolites in cervical cells of female smokers. In this study, we investigated the role of the T3801C (MspI) polymorphism of CYP1A1, a gene encoding an enzyme necessary for the initiation of tobacco based carcinogen metabolism, on cervical cancer risk. The T to C substitution may alter CYP1A1 activities, potentially elevating cervical cancer risk. Since results of gene-disease association studies vary according to the study population, the multi-ethnic population of Malaysia provides an excellent representative cohort for identifying and comparing the cervical cancer risk among the 3 major ethnics in Southeast Asia in relation to CYP1A1 MspI polymorphism. Materials and Methods: A total of 195 Thin Prep Pap smear samples from HPV negative and cancer free females were randomly selected as controls while 106 formalin fixed paraffin embedded samples from females with invasive cervical cancer were randomly selected for the cases group. The polymorphisms were identified using restriction fragment length polymorphism (RFLP) PCR. Results: We found no significant associations between CYP1A1 MspI polymorphism and cervical cancer in the general Malaysian female population. However, upon ethnic stratification, the variant C/C genotype was significantly associated with a 4.66-fold increase in cervical cancer risk in Malay females (95% CI= 1.21-17.9; p=0.03). No significant association was observed in the Chinese and Indian females. Additionally, there were no significant associations in the dominant model and allele frequency model analysis in both the general and ethnically stratified female population of Malaysia. Conclusions: Our findings suggest that the C/C genotype of CYP1A1 MspI polymorphism is associated with the development of cervical carcinoma in the Malay females of Malaysia.

Rahayu Indriasari,Ulfah Nadjamuddin,Dian Sidik Arsyad,Dwi Nastiti Iswarawanti 한국영양학회 2021 Nutrition Research and Practice Vol.15 No.5

BACKGROUND/OBJECTIVES: Many adolescents in developing countries skip breakfast. Innovative nutrition education (NE) strategies are needed to enhance knowledge and skills related to the breakfasts of adolescents in a low socioeconomic setting. The objective was to evaluate short- and long-term effects of a multi-strategy, school-based NE intervention on adolescents" breakfast-related personal influences and behaviors. SUBJECTS/METHODS: An intervention study with a cluster randomized controlled trial design was conducted in 4 senior high schools in Makassar, Indonesia. The multi-strategy NE intervention was delivered for 3 months. Data were collected using a self-administered questionnaire and a 3-day breakfast recall (face-to-face interview). Wilcoxon, McNemar, and Mann-Whitney tests were used to determine intra- and intergroup differences. RESULTS: Unlike knowledge, improvement was observed in attitude and self-efficacy scores in the intervention groups (IGs) (P < 0.01); however, no significant changes were observed in the control group (CG). More students showed improved motivation in the IG than in the CG (P > 0.05). Changes in breakfast frequency and macronutrient intake from breakfast were greater in the IG than in the CG (P < 0.05). CONCLUSIONS: A multi-strategy NE intervention is effective in producing positive changes in breakfast-related attitude, self-efficacy, and motivation of adolescents from a low-middle socioeconomic setting. The intervention improved breakfast frequency and nutrient intake. This intervention has promise for sustaining the observed changes over the long-term.

This paper proposes an integrated lighting enabler system (ILES) based on standard machine-to-machine (M2M) platforms. This system provides common services of end-to-and M2M communication for smart lighting system. It is divided into two sub-systems, namely end-device system and server system. On the server side, the M2M platform OpenMTC is used to receive data from the sensors and send response for activating actuators. At the end-device system, a programmable smart lighting device is connected to the actuators and sensors for communicating their data to the server. Some experiments have been done to prove the system concept. The experiment results show that the proposed integrated lighting enabler system is effective to reduce the power consumption by 25.22% (in average). The proving of significance effect in reducing power consumption is measured by the Wilcoxon method.
