Abstract

Researchers in this study will make it back first mover cross flow turbines with larger dimensions and construction of different power system compared with the first year of study. Sedative tub built with brick-concrete construction also functions as a pipe or penstok so rapidly or loses pressure loss is relatively smaller. Thus this generation systems dinamakam micro hydro Power Wagon Model (PTMMB) are used as flour grinding machine mover. PTMMB relatively cheaper investment and implementation in the field relatively quickly, all these advantages into solution in accelerating the spread and development of micro-hydro power plant to the next. By utilizing a head of 1.5 m and a discharge of 100 l / s, projected another plant can generate power of 1,272 kW. From the test results show that the data are encouraging real turbine efficiency is 86.5% greater than the efficiency of plan / assumption is 85%, and thus the quality of early mover Cross Flow turbines are built quite satisfactory and can be proud of. Generating system efficiency measured above 70% which is 76.1% and the productivity of grinding machine at 100% valve opening position is 50 kg / h, which is quite large productivity is very helpful in increasing the production of grinding

Abstract

Background: Misoprostol is now widely used as an agent for the induction of labor, although the effectiveness of its use in premature rupture of the membrane is questionable.Objectives: To compare the effectiveness of vaginal versus oral administration of misoprostol for induction of labor in term pregnancy with premature rupture of the membranes.Study Design: A retrospective cohortMaterials and Method: The study was conducted at Dr. Sardjito General Hospital Yogyakarta from January 1999 to November 2001. Data were taken from medical record. The inclusion criteria were gestational age of 37 weeks not yet in labor with premature rupture of membranes, singleton gestation, cephalic presentation, reactive fetal heart pattern, and Bishop score s 4. The pregnancy that is complicated by diseases were excluded. Vaginal administration of misoprostol was considered as the exposed group while oral administration was as control. Misoprostol 50 mg had been at six hours interval, for maximal dose of 200 pg. Variable outcomes were effectiveness, duration of induction, mode of delivery, side effects, and newborn asphyxia. Data were processed with SPSS for Window version 10.0, t-Test, chi-square test, relative risk, and binary logistic regression were used for statistical analysis.Result: During the period of three years, there had been 249 cases of premature rupture of membranes that met the inclusion and exclusion criteria consisting of 88 cases exposed group and 88 cases of control. The success rate of the vaginal misoprostol was 80.70% compared to 87.50% in the oral misoprostol with p > 0.05. The cesarean rate from vaginal misoprostol and oral misoprostol were 8.00% versus 3.40% respectively (RR 2.23 and 95% CI 0.62-8.73), the rate of asphyxia in the newborn was 29.50% versus 26.10% (RR 1.13 and 95% CI 0.70-1.82). The rate of side effect, hyperstimulation, was 5.70% versus 1.10% (RR 5.00 and 95% CI 0.60-41.93) in the vaginal group. The length of induction vaginal and oral misoprostol were 10.00 ± 4.86 and 9.76 ± 4.56 hours. There was one case of cesarean section followed with hysterectomy due to urine atony in the vaginal group.Conclusion: The success rate of vaginal misoprostol induction was slightly lower than oral, but it was not statistically significant, as well as the incidence of the first minute of asphyxia. The interval between the administration of drug to complete dilatation in the vaginal and oral group was not different. The rate of cesarean section and hyperstimulation was higher in the vaginal group.Key words: misoprostol - oral and vaginal - effectiveness - premature rupture of membranes - neonatal .asphyxia

Abstract

AbstrakAda anyak penelitian yang membuktikan transfer kolesterol dari ibu ke janin melalui lapisan trofoblas yang membawa partikel LDL (Low Density Lipoprotein) dan HDL (High Density Lipoprotein). Pengambilan dan pemanfaatan LDL oleh plasenta merupakan mekanisme alternatif oleh janin untuk memperoleh asam lemak dan asam amino esensial. Tujuan penelitian ini untuk mengetahui hubungan kadar LDL dan HDL serum ibu hamil aterm dengan berat lahir bayi. Penelitian ini merupakan studi observasional dengan rancangan cross sectional. Dilakukan pemeriksaan kadar LDL dan HDL serum terhadap 31 sampel ibu hamil aterm yang dipilih secara consecutive sampling, kemudiaan saat bayi dari sampel lahir dilakukan penimbangan berat lahir bayi dalam 1 jam setelah lahir dengan keadaan tanpa pakaian. Data dianalisis menggunakan uji korelasi Pearson dilanjutkan dengan uji regresi linier sederhana, nilai p<0.05 dianggap bermakna secara statistik. Rerata kadar LDL serum ibu hamil aterm 138,52±37,86 mg/dl dengan 7 sampel (22,60%) kadar LDL <101 mg/dl. Rerata kadar HDL serum ibu hamil aterm 53,32±17,39 mg/dl dengan 13 sampel (41,90%) kadar HDL <48 mg/dl. Rerata berat lahir bayi 3150,00±489,89 gram dengan 2 sampel (6,50%) memiliki bayi dengan berat<2500 gram. Terdapat hubungan positif antara kadar LDL serum ibu hamil aterm dengan berat lahir bayi, kekuatan hubungan lemah (r=0,258), secara statistik tidak bermakna (p=0,161). Terdapat hubungan positif antara kadar HDL serum ibu hamil aterm, kekuatan hubungan sangat lemah (r=0,035), secara statistik tidak bermakna (p=0,850). Kesimpulan penelitian tidak terdapat hubungan kadar LDL dan HDL serum ibu hamil dengan berat lahir bayi.Kata kunci: kadar LDL serum, kadar HDL serum, ibu hamil aterm, berat lahir bayiAbstractMany studies proved that the transferring of cholesterol from mother to fetus through the trophoblastic layer carried LDL (Low Density Lipoprotein) and HDL (High Density Lipoprotein) particles. Uptake and usage of LDL by placenta to the fetus is an alternative mechanism to obtain fatty acids and essential amino acids. The objective of this study was to determine whether there is a relationship between LDL and HDL serum level of pregnant women at term with infant birth weight. This study was an observational study with cross sectional design. Examination of LDL and HDL serum level to 31 term pregnancy sample choose by consecutive sampling, and then infant’s birth weight was counted within 1 hour after birth without clothes. The data analyzed with Pearson correlation statistical test followed by simple linier regression statistical test. The mean of LDL serum level term pregnancy was 138,52±37,86mg/dlwith7 samples(22.60%) in LDL levels<101 mg/dl. The mean of HDL serum level at term pregnancy was 53,32±17,39 mg/dlwith 13 samples (41,90%) in HDL levels<48 mg/dl. The mean of infant birth weight was 3150,00±489,89 grams with 2 samples (6,50%) had infants weighing < 2500 grams. There is a positive relationship between LDL serum levels term pregnancy with birth weight infants, the strength of the relationship is weak (r =0,258), were not significant statistically (p=0,161). There is a positive relationship between HDL serum levels at term pregnancy with birth weight infants, the strength ofthe relationshipis veryweak(r =0,035), were not significant statistically (p=0,850). In conclusion there was no correlation of serum levels of LDL and HDL at term pregnant with birth weight.

Abstract

The piping system is an important feature in the industrial world because it has an effective and efficient transportation function used for shipping such as liquid and gas fluids. Prevention of damage either leakage or blockage is very important because it can reduce the number of losses both economic, natural environment, and even loss of life. The use of sound signals to detect and find leaks in pipes with experimental studies. This method can be used because it is very sensitive to discontinuities in the pipe that can detect damage at a relatively lower cost. This method uses sound impulses emitted through the loudspeaker as excitation and the response of the sound signal will be recorded using a dual microphone sensor. Sound signals are given for leakage under conditions of using water and without water of different sizes, positions and polar sides. The sound signal data will be processed using the Fast Fourier Transform and Wavelet Transform methods. The test results showed that the amount of damage given is directly proportional to the amplitude generated and the wavelet coefficient of each microphone sensor will increase as it approaches the polar side of the damage.
