Storage Space Optimisation for Green Data Center

The characteristic that determines a green data center is low amount of carbon footprint produced by its physical data storages. Increasing demand of data volumes in many data intensive applications call for additional physical data storages that are not only impractically large to maintain, but also contribute to the amount of carbon footprint produced. It is argued in this paper that, if storage space can be optimised to gain free spaces, the storage space requirement can be reduced. In this paper, a model to optimize database storage space by mining functional dependencies that are present among data sets is proposed. Sample data sets from the microbial domain have been used where data of large data volume raises storage space concern. The initial results of the implementation of the model that is necessary in designing a complete space optimization algorithm are presented

Handling Failures in Data Quality Measures

Successful data quality (DQ) measure is importantfor many data consumers (or data guardians) to decide on theacceptability of data of concerned. Nevertheless, little is knownabout how “failures” of DQ measures can be handled by dataguardians in the presence of factor(s) that contributes to thefailures. This paper presents a review of failure handling mechanismsfor DQ measures. The failure factors faced by existing DQmeasures will be presented, together with the research gaps inrespect to failure handling mechanisms in DQ frameworks. Inparticular, by comparing existing DQ frameworks in terms of: theinputs used to measure DQ, the way DQ scores are computed andthey way DQ scores are stored, we identified failure factorsinherent within the frameworks. Understanding of how failurescan be handled will lead to the design of a systematic failurehandling mechanism for robust DQ measures

Impact of Electron Radiation Dose to the Performance of Half-Wave Rectifier and Converter Circuits with Silicon Carbide Schottky Diode

Half-wave rectifier; buck; and boost converter with electron-irradiated, high-voltage silicon carbide Schottky power diodes from CREE, Inc., performance were studied and presented in this paper subjected to electron radiation. The diodes were irradiated by high-energy (3 MeV) electrons with doses ranging from 1 to 5 MGy. The performance of the circuits in term of the output voltage were measured before and after the diodes being irradiated. It was observed, at 4 MGy, the half-wave rectifier output voltage degrades by 6.2 times as compared to before irradiation. Meanwhile, the output voltage of the buck converter degrades by 1.7 times; and for boost converter, the degradation of the output voltage is approximately 4.6 times for 4MGy radiation. These degradations are believed to be due to the increase in the series resistance of the Schottky diodes which is caused by the defects introduced inside the semiconductor during the irradiation and also the increase of turn-on voltage of the diodes after being irradiated

Faktor Risiko Kematian Neonatal Dini di Rumah Sakit Bersalin

Infant mortality rate in Indonesia is still high. Fifty percent of the neonatal mortality occurred among low birth weight infants (LBWI) and neonatal mortality within 7 days of life accounted for 50% of total infant mortalities. This study was aimed to examine the extent of early neonatal mortality risk by antenatal care (ANC), Tetanus Toxoid (TT) immunization status of pregnant women, anemia during pregnancy, birth weight of neonatal, parity status, and hypothermia status.This study was a case control study with direct interview to respondents, conducted in the Maternity Hospital of Makassar with 40 cases and 120 controls. Samples were selected by purposive sam- pling. Study results indicated that risk factor of early neonatal mortality were ANC (p value = 0,000; odds ratio, OR = 7,33; CI 95% = 2,966 - 18,129), TT immunization status (p value = 0,000; OR = 19,205; CI 95% = 7,902 - 46,678), pregnancy anemia (p value = 0,000; OR = 32,818; CI 95% = 7,549 - 142,674), birth weight (p value = 0,000; OR = 122,212; CI 95% = 32,324 - 462,068), parity status (p value = 0,000; OR = 5,537; CI 95% = 2,029 - 15,111), asphyxia status (p value = 0,000; OR = 8,197; CI 95% = 0,452 - 2,745), whereas hypothermia status (p value = 0,815; OR = 1,114; 0,452 - 2,745) was not a risk factor. Results of logistic regression multivariate analysis indicated that infant\u27s birth weight was the most risk factor of early neonatal mortality (p value = 0,000). Specific surveillance program for high risk neonatal needed to be arranged in all health centers

The Effect of Artificial Feeding Treatments on Predatory and Pollinating Ants in Cayenne Pepper Plants

Pests have the potential to reduce the quality and quantity of cayenne pepper production. Pest control is done by utilizing natural enemies, such as ants by being stimulated with artificial food. This study aims to observe the population of dominant species and the effect of various artificial feeding treatments on ants that act as predators or pollinators in chili plants. The study was arranged in a Randomized Group Design (RGD) with 5 treatments, namely P0: Control (no pellet or sugar solution treatment); P1: 10 g artificial feed pellets; P2: 10% sugar solution; P3: 10% sugar solution and 10 g artificial feed pellets; and P4: 10 g artificial feed pellets (put into artificial nest) which was repeated 4 times.  Observations were made five times at three-day intervals. Data were analyzed by calculating the species diversity index (H'), species dominance index (C), and ant population. Based on the results, the ant diversity index in this experiment was classified as moderate at 1.17 (H' 1.0-3.0) and the ant dominance index was 0.35 (low: C<0.5). Ant identification revealed four species from three sub-families: Myrmicinae, Dolichodorinae, and Formicinae, namely Pheidole sp., Monomorium sp., Tapinoma sp., and Paratrechina sp. While species that have the potential as predators or pollinators on chili plants are Tapinoma sp.. Artificial feeding with treatment P3 (10 g artificial feed and 10% sugar solution) can have an effect and increase the population of Tapinoma sp. ants with an average of 81.95 heads on chili plants

Assessment of llness perception of diabetic patients with periodontitis

Illness perception is the organized cognitive representations or beliefs that patients have about their illness. These perceptions are important determinants of behavior and are associated with important illness outcomes. This study aimed to assess the illness perception of diabetic patients with periodontitis toward Diabetes Mellitus and periodontitis and its association with the severity of periodontitis. A cross sectional prospective study was conducted among total of 22 diabetic patients with periodontitis attending the periodontics Kulliyyah of Dentistry (KOD) Polyclinic, International Islamic University Malaysia (IIUM). Periodontal clinical examination was done to the patients and the severity of periodontitis was determined by the clinical attachment loss (CAL).The Brief Illness Perception Questionnaire (B-IPQ) was used to assess illness perception towards Diabetes and periodontitis. The mean score of illness perception in diabetes mellitus is higher than periodontitis in terms of timeline, personal control, concern, and understanding. The patients that perceive the illness in a serious way in terms of consequences, treatment control, concern, and emotional domain have lower mean CAL. There is significant relationship between gender and illness perception towards Diabetes Mellitus and periodontitis for identity domain where male patients showed p value of 0.04 and 0.032 respectively. This study showed that patients consider Diabetes Mellitus to be more serious than periodontitis despite the severity of their periodontitis. This highlights the intense need of proper education about the oral complications of Diabetes Mellitus and oral health in general

Synthesis of poly(acrylonitrile-co-divinylbenzene-co-vinylbenzyl chloride)-derived hypercrosslinked polymer microspheres and a preliminary evaluation of their potential for the solid-phase capture of pharmaceuticals

Poly[acrylonitrile (AN)‐co‐divinylbenzene (DVB)‐co‐vinylbenzyl chloride (VBC)] terpolymers were synthesized by precipitation polymerization in the form of porous polymer microspheres. The poly(AN‐co‐DVB‐co‐VBC) polymers were then hypercrosslinked, via a Friedel‐Crafts reaction with FeCl3 in nitrobenzene, to provide a significant uplift in the specific surface areas of the polymers. FTIR spectra of the hypercrosslinked poly(AN‐co‐DVB‐co‐VBC)s showed that the chloromethyl groups derived from VBC were consumed by the Friedel‐Crafts reactions, which was consistent with successful hypercrosslinking. Hypercrosslinking installed a number of new, small pores into the polymers, as evidenced by a dramatic increase in the specific surface areas upon hypercrosslinking (from ∼530 to 1080 m2 g−1). The hypercrosslinked polymers are very interesting for a range of applications, not least of all for solid‐phase extraction (SPE) work, where the convenient physical form of the polymers (beaded format), their low mean particle diameters, and narrow particle size distributions, as well as their high specific surface areas and polar character (arising from the AN residues), make them attractive candidates as SPE sorbents. In this regard, in a preliminary study one of the hypercrosslinked polymers was utilized as an SPE sorbent for the capture of the polar pharmaceutical diclofenac from a polar environment
