    El presente desarrollo de investigación fue de tipo descriptivo-aplicativo con el fin de resolver un problema social, cuyo objetivo principal fue dotar de agua y alcantarillado a 301 familias de las localidades de Huañipo y San Antonio; con la visión de evitar enfermedades que afecten a la salud de todos los pobladores de la localidad de Huañipo. Se ejecutó el levantamiento topográfico, el estudio de suelos y cálculos hidrológicos. El presente proyecto se origina por la necesidad urgente de la población de contar con abastecimiento de agua potable continuo, debido a la ineficiencia del servicio de agua potable y a la inexistencia del servicio de alcantarillado en las localidades de Huañipo y San Antonio. Como consecuencia de ello existe la presencia de enfermedades infectocontagiosas, se hace necesario darle solución al problema identificado a fin de satisfacer las necesidades básicas de la población de dichas zonas. La población de referencia fue considerada la población del distrito de Tingo de Ponasa que fue un total de 3957 habitantes aproximadamente, y la población objetivo fue el 26% de la población que vive en la Localidades de Huañipo y San Antonio, que fue de 1037 habitantes, aproximadamente, provenientes de familias en su mayoría dedicadas a la actividad agropecuaria y forestal, comercio y servicios

    STUDI KUALITAS PUPUK FOSFOR (P) DAN KALIUM (K) YANG DIJUAL DI KIOS PENYALUR RESMI PUPUK DI KABUPATEN BOGOR, CIANJUR, DAN SUKABUMI, JAWA BARAT

    Peredaran pupuk anorganik fosfor (P) dan kalium (K) semakin merajalela dan memprihatinkan. Penjualan pupuk yang tidak berkualitas ini, jelas sangat merugikan petani dan pemerintah karena dapat menggagalkan panen petani dan sekaligus juga dapat menggagalkan program Pemerintah seperti Program Peningkatan Produksi Beras Nasional (P2BN) dan Program Ketahanan serta Keamanan Pangan. Pemerintah telah membentuk Komisi Pengawasan Pupuk dan Pestisida (KP3) di setiap kabupaten dan kota, yang bertugas melakukan pengawasan peredaran dan kualitas pupuk dan pestisida, akan tetapi badan ini tidak dapat menjalankan fungsinya dengan baik. Studi ini dilakukan dengan tujuan untuk mengetahui kualitas pupuk P dan K yang dijual ke masyarakat di kios resmi penyalur pupuk di tiga kabupaten yaitu Bogor, Cianjur dan Sukabumi. Kios resmi penjual pupuk dipilih berdasarkan kecamatan penyaluran pupuk subsidi untuk tanaman pangan dan hortikultura. Dalam studi ini telah diambil 29 contoh pupuk yang terdiri atas: 10 contoh pupuk SP-36, 10 contoh pupuk P selain SP-36, dan 9 contoh pupuk K. Hasil analisis contoh pupuk menunjukkan bahwa pupuk SP-36 yang dijual di kios resmi memiliki kualitas yang baik dengan kadar P2O5 sekitar 35-36% P2O5. Namun pupuk P selain SP-36 yang terdiri dari berbagai merek yang dipasarkan di kios resmi, seluruhnya (9 contoh pupuk) berkualitas sangat rendah, dengan kandungan P2O5 berkisar dari 0.21 sampai 1.04% P2O5. Hanya empat (44%) dari sembilan contoh pupuk K yang berkualitas baik dengan kandungan kalium lebih dari 60% K2O, sedangkan yang lima contoh pupuk kalium lainnya (56%) berkualitas sangat buruk dengan kandungan kalium antara 0.02 sampai 0.08% K2O

    Robust Inference of Monocot Deep Phylogeny Using an Expanded Multigene Plastid Data Set

    Get PDF
    We use multiple photosynthetic, chlororespiratory, and plastid translation apparatus loci and their associated noncoding regions (ca. 16 kb per taxon, prior to alignment) to make strongly supported inferences of the deep internal branches of monocot phylogeny. Most monocot relationships are robust (an average of ca. 91 % bootstrap support per branch examined), including those poorly supported or unresolved in other studies. Our data strongly support a sister-group relationship between Asparagales and the commelinid monocots, the inclusion of the orchids in Asparagales, and the status of Petrosaviaceae as the sister group of all monocots except Acorus and Alismatales. The latter finding supports recognition of the order Petrosaviales. Also strongly supported is a placement of Petermannia disjunct from Colchicaceae (Liliales) and a sister-group relationship between Commelinales and Zingiberales. We highlight the remaining weak areas of monocot phylogeny, including the positions of Dioscoreales, Liliales, and Pandanales. Despite substantial variation in the overall rate of molecular evolution among lineages, inferred amounts of change among codon-position data partitions are correlated with each other across the monocot tree, consistent with low incongruence between these partitions. Ceratophyllum and Chloranthaceae appear to have a destabilizing effect on the position of the monocots among other angiosperms; the issue of monocot placement in broader angiosperm phylogeny remains problematic

    The Standard Model Prediction for epsilon'/epsilon

    Get PDF
    We present a detailed analysis of epsilon'/epsilon within the Standard Model, taking into account the strong enhancement through final-state interactions identified in refs. [1] and [2]. The relevant hadronic matrix elements are fixed at leading order in the 1/N_C expansion, through a matching procedure between the effective short-distance Lagrangian and its corresponding low-energy description in Chiral Perturbation Theory. All large logarithms are summed up, both at short and long distances. Two different numerical analyses are performed, using either the experimental or the theoretical value for epsilon, with compatible results. We obtain Re(epsilon'/epsilon) = (1.7 +- 0.9)*10^{-3}. The error is dominated by the uncertainty in the value of the strange quark mass and the estimated corrections from unknown 1/N_C-suppressed local contributions. A better estimate of the strange quark mass would reduce the uncertainty to about 30%. The Standard Model prediction agrees with the present experimental world average Re(epsilon'/epsilon) =(1.93 +- 0.24)*10^{-3}.Comment: Latex, 35 page

    Effect of 6-months of physical exercise on the nitrate/nitrite levels in hypertensive postmenopausal women

    Get PDF
    <p>Abstract</p> <p>Background</p> <p>Evidences have showed that the incidence of arterial hypertension is greater in postmenopausal women as compared to premenopausal. Physical inactivity has been implicated as a major contributor to weight gain and abdominal obesity in postmenopausal women and the incidence of cardiovascular disease increases dramatically after menopause. Additionally, more women than men die each year of coronary heart disease and are twice as likely as men to die within the first year after a heart attack. A healthy lifestyle has been strongly associated with the regular physical activity and evidences have shown that physically active subjects have more longevity with reduction of morbidity and mortality. Nitric oxide (NO) produced by endothelial cells has been implicated in this beneficial effect with improvement of vascular relaxing and reduction in blood pressure in both laboratory animals and human. Although the effect of exercise training in the human cardiovascular system has been largely studied, the majority of these studies were predominantly conducted in men or young volunteers. Therefore, the aim of this work was to investigate the effects of 6 months of dynamic exercise training (ET) on blood pressure and plasma nitrate/nitrite concentration (NOx<sup>-</sup>) in hypertensive postmenopausal women.</p> <p>Methods</p> <p>Eleven volunteers were submitted to the ET consisting in 3 days a week, each session of 60 minutes during 6 months at moderate intensity (50% of heart rate reserve). Anthropometric parameters, blood pressure, NOx<sup>- </sup>concentration were measured at initial time and after ET.</p> <p>Results</p> <p>A significant reduction in both systolic and diastolic blood pressure values was seen after ET which was accompanied by markedly increase of NOx<sup>- </sup>levels (basal: 10 ± 0.9; ET: 16 ± 2 μM). Total cholesterol was significantly reduced (basal: 220 ± 38 and ET: 178 ± 22 mg/dl), whereas triglycerides levels were not modified after ET (basal: 141 ± 89 and ET: 147 ± 8 mg/dl).</p> <p>Conclusion</p> <p>Our study shows that changing in lifestyle promotes reduction of arterial pressure which was accompanied by increase in nitrite/nitrate concentration. Therefore, 6-months of exercise training are an important approach in management arterial hypertension and play a protective effect in postmenopausal women.</p
