Power generation from waste of IC engines

Several methods for waste thermal energy recovery from internal combustion engine (ICE) have been studied by using supercharger or turbocharger and /or combined. This study presents an innovative approach on power generation from waste of IC engine based on coolant and exhaust. The waste energy harvesting system of coolant (weHSc) is used to supply hot air at temperatures in the range of 60–70 C directly into the engine cylinder, which would be useful to vaporize the fuel into the cylinder. The waste energy harvesting system of exhaust system (weHSex) has been developed with integrating fuzzy intelligent controlled Micro-Faucet emission gas recirculation (MiF-EGR) and thermoelectric generator (TEG). In this study the MiF-EGR (micro-facet exhaust gas recirculation) will be used to maintain the intake temperature 70 C by keeping flow of the exhaust to the engine cylinder chamber and to increase the engine volumetric efficiency. The TEG produces electrical power from heat flow across a temperature gradient of exhaust and delivers DC electrical power to the vehicle electrical system which could reduce the load of the alternator by as much as 10%. The performance of weHS equipped engine has been investigated by using GT suite software for optimum engine speed of 4000 rpm. The result shows that specific fuel consumption of engine has improved by 3% due to reduction of HC formation into the engine combustion chamber causes significantly improved the emission. While, the brake power has been increased by 7% due to the fuel atomization and vaporization at engine intake temperature 70 C

APLIKASI SINC (SPIRITUAL ISLAMIC NURSING CARE) DALAM PEMENUHAN KEBUTUHAN SPIRITUAL PASIEN DI RUMAH SAKIT

Spiritual merupakan salah satu kebutuhan dasar yang dibutuhkan oleh setiap manusia. Seseorang yang dirawat diruang Intensif Care Unit (ICU) dengan kondisi kritis maupun terminal pada umunnya takut akan sakit fisik, ketidaktahuan, dan kematian. Bagi pasien terminal maupun kritis, sumber penyembuhan yang utama ialah spiritualitas mereka. Sarana dan Prasarana sangat berpengaruh dalam memberikan pelayanan spiritual kepada pasien. Tujuan studi ini adalah Diketahuinya implementasi kebutuhan spiritual pasien dengan Menggunakan Aplikasi SINC (Spiritual Islamic Nursing Care)”. Sehingga dapat memberikan rekomendasi guna memaksimalkan pemenuhan kebutuhan spiritual pasien di Ruangan ICU Rumah Sakit Labuang Baji Makassar. Metode yang digunakan adalah Studi Kasus Kualitatif dengan melakukan Pengkajian, Analisis Swot, Identifikasi Masalah serta POA (Planning Of Action). Teknik pengumpulan data dilakukan dengan cara wawancara, observasi dan data sekunder dari studi dokumentasi data Rumah Sakit. Responden dipilih dengan cara Teknik Accidental Sampling. Hasil analisis didapatkan bahwa pelayanan spiritual belum dilakukan secara optimal, hal ini dikarenakan kurangnya peran perawat dalam memenuhi kebutuhan spiritual pasien, kurangnya fasilitas penunjang pemenuhan kebutuhan Spiritual, tidak terdapat SOP pemenuhan kebutuhan spiritual, tidak terdapat pendokumentasian keperawatan mengenai pengkajian kebutuhan spiritual pasien dan tidak terdapat anggaran khusus yang disediakan ruangan untuk pemenuhan atau pembelian alat-alat spiritual, maupun untuk mengundang pemuka agama. Dalam mengatasi masalah pelayanan spiritual, makasi dilakukan sosialisasi aplikasi SINC (Spiritual Islamic Nursing Care) kepada Petugas dan kepada pasien/keluarga pasien. Kesimpulan dari analisis fungsi manajemen keperawatan  ialah pasien/keluarga pasien merasa puas terhadap pemenuhan kebutuhan spiritual dengan Aplikasi SINC (Spiritual Islamic Nursing Care) juga sebagai fasilitas dalam memberikan pelayanan spiritual kepada pasien.

Sustainable solid waste management knowledge and practices among rural community in Malaysia

This study aimed to explore the current knowledge and practices of sustainable solid waste management among the rural community in Malaysia. It is becoming a significant concern to promote sustainable practices to the rural community, given that the facilities of solid waste disposal are noticeably lacking in the rural area. Data was gathered through a survey questionnaire in two phases. The first phase of the survey examines the community’s current solid waste practices and their knowledge about solid waste management. The second phase gathered the community’s level of knowledge about sustainable solid waste management after a briefing and demonstration about composting. A total of 55 respondents from a rural community in northern Malaysia were selected via a convenience sampling method for the purpose of this study. Empirical results show that while the existing knowledge and practices of sustainable solid waste are low among the rural community, their knowledge about sustainable practices improves significantly after the briefing and practical activity. The study conveys some practical implications to the need for environmental awareness and education to promote sustainable practices in managing waste in the rural areas

Lipid Metabolism Links Nutrient-Exercise Timing to Insulin Sensitivity in Men Classified as Overweight or Obese

Context Pre-exercise nutrient availability alters acute metabolic responses to exercise, which could modulate training responsiveness. Objective To assess acute and chronic effects of exercise performed before versus after nutrient ingestion on whole-body and intramuscular lipid utilization and postprandial glucose metabolism. Design (1) Acute, randomized, crossover design (Acute Study); (2) 6-week, randomized, controlled design (Training Study). Setting General community. Participants Men with overweight/obesity (mean ± standard deviation, body mass index: 30.2 ± 3.5 kg⋅m-2 for Acute Study, 30.9 ± 4.5 kg⋅m-2 for Training Study). Interventions Moderate-intensity cycling performed before versus after mixed-macronutrient breakfast (Acute Study) or carbohydrate (Training Study) ingestion. Results Acute Study—exercise before versus after breakfast consumption increased net intramuscular lipid utilization in type I (net change: –3.44 ± 2.63% versus 1.44 ± 4.18% area lipid staining, P 0.05). However, postprandial insulinemia was reduced with exercise training performed before but not after carbohydrate ingestion (P = 0.03). This resulted in increased oral glucose insulin sensitivity (25 ± 38 vs –21 ± 32 mL⋅min-1⋅m-2; P = 0.01), associated with increased lipid utilization during exercise (r = 0.50, P = 0.02). Regular exercise before nutrient provision also augmented remodeling of skeletal muscle phospholipids and protein content of the glucose transport protein GLUT4 (P < 0.05). Conclusions Experiments investigating exercise training and metabolic health should consider nutrient-exercise timing, and exercise performed before versus after nutrient intake (ie, in the fasted state) may exert beneficial effects on lipid utilization and reduce postprandial insulinemia

Breakfast habits and differences regarding abdominal obesity in a cross-sectional study in Spanish adults: The ANIBES study

Background: Previous studies have indicated that breakfast has a protective effect against obesity. The aim of this study was to describe the breakfast habits of the Spanish adult population and to assess the possible association between breakfast frequency and the presence of abdominal obesity, in a cross-sectional analysis of the ANIBES Study. Methods: A representative sample of 1655 Spanish adults (aged 39±12 y; (mean±sd)) from the ANIBES Study was investigated. The final field work was carried out from mid-September to November (three months) 2013. Collected data included a dietary data collected by a 3-days food record, and health, socioeconomic, physical activity and anthropometric (weight, height and waist circumference) data. Abdominal obesity was defined as having a waist-to-height ratio ≥0.5. The adults were also classified into three groups based on the number of days they ate breakfast (never (0/3 days), sometimes (1-2/3 days) and always (3/3 days)). Logistic regression analyses were used to evaluate the association between breakfast and abdominal obesity. Results: In total, 3.6% of adults skipped breakfast and 14.1% ate breakfast sometimes. Having always breakfast was negatively associated with abdominal obesity [OR = 0.738 (0.558–0.975) p = 0.033]. The odds of abdominal obesity after full adjustment (age, gender, and educational and activity level) were 1.5 times higher for those who skipped breakfast when compared to those who always have breakfast. By correcting the model considered for other variables, the odds among smokers decreased when they have breakfast sometimes [OR = 0.032 (0.003–0.387) p = 0.007] and always [OR = 0.023 (0.002–0.270) p = 0.003] comparing with smokers who skip breakfast. Conclusion: Breakfast frequency could be negatively associated with abdominal obesity, especially among smokers.ANIBES Study was financially supported by Coca Cola Iberia through an agreement with the Spanish Nutrition Foundation (FEN)
