Pengaruh Variasi Putaran Mesin, Komposisi Campuran Bioetanol dan Tipe Vacuum Tube terhadap Komsumsi Bahan Bakar dan Komposisi Gas Buang pada Motor Bakar Bensin Empat Langkah Satu Silinder

Experimental study on the installation of a vacuum tube in intake manifold has been done by observation at the effect of variations engine rotation and composition of bioethanol mixture with regard to fuel consumption and exhaust gas composition. This study used fuel E20, E30 and E40, the type of vacuum tube 4Y2 and Posh. Tests carried out on variations of the engine rotation 3000, 3500, 4000, 4500 and 5000 rpm. As result fuel consumption tends to increase as increasing engine rotation, it is more efficient with increasing ethanol in the fuel mixture and use a vacuum tube, the most efficient happened on fuel E40 with the installation of a vacuum tube type Posh in engine rotation 3000 rpm with consumption 0,21 L/hour. CO exhaust gas tends to decrease with increasing engine rotation, the ethanol in the fuel mixture with the installation of a vacuum tube, the lowest occurred on fuel E40 with installation a vacuum tube type Posh in engine rotation 5000 rpm with emission 0,06 %. CO2 tends to increase with increasing engine rotation, the ethanol in the fuel mixture and the installation of a vacuum tube, the highest on fuel E40 with a vacuum tube type Posh in engine rotation 5000 rpm with emission 13,60 %. HC tends to decrease with increasing engine rotation, the ethanol in the fuel mixture and the installation of a vacuum tube, the lowest occurred on fuel E40 with a vacuum tube type Posh in engine rotation 5000 rpm with emission 90 ppm

Hasil penelitian menunjukkan bahwa pada kedalaman 3 m jumlah individu ikan karangyang berhasil diidentifikasi berjumlah 1.588 individu yang terdiri dari 58 jenis dari 17 famili, sedangkan pada kedalaman10 m jumlah individu ikan karang yang ditemukan berjumlah 1.846 individu yang terdiri dari 69 jenis dari 16 famili.Nilai indeks keanekaragaman tergolong sedang, sedangkan indeks kesamaan, dan dominansi jenis tergolong rendah

Real economic activity and earnings management from a cross-country perspective

This paper provides empirical evidence on differences in the extent of earnings management across countries. I use an earnings management detection model developed by Leuz et al. (2003) to determine this extent in Germany, Japan, and the USA. Based on previous research, I hypothesize due to differences in prevailing institutional factors in those countries that earnings management is most pervasive in Germany and least pervasive in the USA with Japan exhibiting values in between. The results mostly confirm the hypothesis. Moreover, I investigate a possible link between real economic performance of a country and the extent of earnings management. I expect a negative correlation between them, whereas the intensity of this relation decreases with increasing pervasiveness of accounts manipulation in a country. Empirical results confirm these hypotheses partly

Cardiovascular Health in Pregnant Women and Their Children - The Generation R Study

__Abstract__ Cardiovascular disease is a major public health problem in the general adult population. 1 Cardiovascular disease leads to over 17.3 million deaths per year and is the leading cause of death and disability worldwide.1 In the Netherlands, cardiovascular disease accounts for approximately 30% of current mortality rates among men and women.2 Because of the clinical impact that cardiovascular and metabolic diseases have at older ages, research into related risk factors has mostly been focused on adults. However, in the last decades, an accumulating body of evidence suggested that cardiovascular health in younger age groups also has major long-term public health implications

¿Un 'discours aux architectes'?

El artículo retorna sobre el profundo impacto que produjeron los temas reaccionarios en la modernidad francesa tras la Primera Guerra Mundial. Para ello, considera el regionalismo en las permutaciones de la Segunda Guerra Mundial y explica sus diferentes significados en Italia y Alemania como base interpretativa para el caso de España. Aplica la distinción entre el regionalismo, el parroquialismo y el provincialismo, considera su susceptibilidad a las condiciones de neo-, pseudo-, y faux-, y diferencia los conceptos de hibricidad y eclecticismo Beaux-Arts. Estas condiciones llevan a su fin la distancia de la obra de Le corbusier con el regionalismo en los años 30. Después de la Segunda Guerra Mundial lo vernacular reemplazó al regionalismo y Gran Bretaña emergió por su posición insular respecto a la vanguardia histórica europea, que por su antagonismo entre el romanticismo, nuevo humanismo, nuevo empirismo, nueva pintoresca y el abandono atropellado vernacular del nuevo brutalismo, consigue crear una ruptura con los años de entreguerras

Maternal obesity during pregnancy and cardiovascular development and disease in the offspring

Maternal obesity during pregnancy is an important public health problem in Western countries. Currently, obesity prevalence rates in pregnant women are estimated to be as high as 30 %. In addition, approximately 40 % of women gain an excessive amount of weight during pregnancy in Western countries. An accumulating body of evidence suggests a long-term impact of maternal obesity and excessive weight gain during pregnancy on adiposity, cardiovascular and metabolic related health outcomes in the offspring in fetal life, childhood and adulthood. In this review, we discuss results from recent studies, potential underlying mechanisms and challenges for future epidemiological studies

Improving Cervical Cancer Prevention by HPV Self-sampling, Colposcopy and Biomarkers

__Abstract__ The worldwide incidence rate of cervical cancer is around 500 000 per year with a mortality rate of around 270 000 women per year. With these figures, it represents the third most common cancer among women worldwide, after breast and colorectal cancer. However, the incidence varies widely among countries; with an average incidence of 452 000 new cases per year in developing countries versus 76 000 new cases per year in developed countries (Figure 1). This lower incidence of cervical cancer in developed countries is at least partially the result of organized cervical cancer screening programs, which lead to earlier detection of cervical cancer and treatable premalignant stages. Since the introduction of the national orga
