Pengembangan Bioteknologi Pupuk Hijau Plus Berbasis Vegetasi Sekunder untuk Meningkatkan Produksi Kacang Tanah Lokal pada Lahan Kering Marginal

The objective of this study was to increase growth and yield of three local peanut genotypes by application of green manure. The pot experiment was carried out at Watuputih, Muna, Southeast Sulawesi. Completely Randomized Design was used in a factorial pattern, replicated three times. The first factor was genotype of local peanut, consisted of 3 genotypes, namely : (1) Wadaga, (2) Lasehao and (3) Parigi, and the second factor was green manure, consisted of 4 application rates, namely : (1) 0 ton ha-1, (2) 5 ton ha-1, (3) 10 ton ha-1 and (4) 15 ton ha-1.The experiment results showed that application of green manure had significant effects on increased N and P nutrient uptake, nitrat reductase enzymes, yield components and yields. Parigi genotype response to application of green manure was better than Wadaga and Lasehao

Dynamic models for Large Eddy Simulation of compressible flows with a high order DG method

The impact of dynamic models for applications to LES of compressible flows is assessed in the framework of a numerical model based on high order discontinuous finite elements. The projections onto lower dimensional subspaces associated with lower degree basis functions are used as LES filter, along the lines proposed in Variational Multiscale templates. Comparisons with DNS results available in the literature for plane and constricted channel flows at Mach numbers 0.2, 0.7 and 1.5 show clearly that the dynamic models are able to improve the prediction of most key features of the flow with respect to the Smagorinsky models employed so far in a VMS-DG context

Respons Pertumbuhan Dan Produksi Kedelai Hasil Seleksi Terhadap Pemberian Asam Askorbat Dan Inokulasi Fungi Mikoriza Arbuskular Di Tanah Salin

Using of saline land to grow up soybean has constraints such yield decreasing. By using ofsaline tolerant soybean, using ascorbate acid, and inoculation of mychorrizha vesicular arbuscular(MVA) aimed to increasing growth and yield of soybean in saline land.This research was conductedat Kecamatan Percut Sei Tuan Kabupaten Deli Serdang in Februari – Mei 2013, using split split plotdesign with three factors, i.e. variety of saline tolerant soybean (Grobogan no selection andGrobogan F4 selection), giving of ascorbate acid (0 dan 500 ppm) and MVA isolate (MVA type 1,type 2, type 3, type 4 and type 5). Parameter observed were plant height, number of leaves, numberof productive branches, production per plant.The result of the research showed that using of salinetolerant soybean significantly increase all parameters observed. Giving of ascorbate acidsignificantly increase number of productive branches. Inoculation of MVA significantly effect allparameters observed. Interaction between variety of saline tolerant soybean and giving ascorbateacid were not significantly effect all parameters observed. Interaction between variety of salinetolerant soybean and giving of MVA significantly effected number of leaves 5 week after planting(WAP) and production per plant. Interaction between giving of ascorbate acid and MVA were notsignificantly effect all parameters observed. Interaction of three factors were not significantly effectall parameters observed

Penelitian ini bertujuan untuk mengetahui pengaruh pemberian vermikompos dan pupuk P terhadap pertumbuhan tanaman kedelai. Penelitian ini dilaksanakan di lahan percobaan Fakultas Pertanian USU (± 25 m dpl) pada Maret – Juni 2015 menggunakan Rancangan Acak Kelompok faktorial 2 faktor yaitu pemberian vermikompos (0, 0,25, 0,5 dan 0,75 kg/polibag) dan pemberian pupuk P (0, 0,625, 1,25 dan 1,825 g/polibag). Parameter yang diamati antara lain tinggi tanaman (cm), diameter batang (mm), umur berbunga (hari), bobot basah akar (g), bobot kering akar (g), bobot basah tajuk (g), bobot kering tajuk (g), volume akar (ml), jumlah cabang produktif, jumlah polong per tanaman, jumlah polong berisi, bobot 100 biji kering (g) dan umur panen (hari). Hasil penelitian menunjukkan bahwa pemberian vermikompos dan pupuk P berpengaruh nyata terhadap semua parameter kecuali umur panen (hari) dan bobot 100 biji kering. Interaksi antara vermikompos dan pupuk P berpengaruh nyata terhadap umur berbunga tanaman kedelai. Hasil yang terbaik diperoleh pada dosis vermikompos 0,75 kg/polibag dan pupuk P 0,625 g/polibag

Concurrent validity and reliability of the Community Balance and Mobility scale in young-older adults

Background: With the growing number of young-older adults (baby-boomers), there is an increasing demand for assessment tools specific for this population, which are able to detect subtle balance and mobility deficits. Various balance and mobility tests already exist, but suffer from ceiling effects in higher functioning older adults. A reliable and valid challenging balance and mobility test is critical to determine a young-older adult’s balance and mobility performance and to timely initiate preventive interventions. The aim was to evaluate the concurrent validity, inter- and intrarater reliability, internal consistency, and ceiling effects of a challenging balance and mobility scale, the Community Balance and Mobility Scale (CBM), in young-older adults aged 60 to 70 years. Methods: Fifty-one participants aged 66.4 ± 2.7 years (range, 60–70 years) were assessed with the CBM. The Fullerton Advanced Balance scale (FAB), 3-Meter Tandem Walk (3MTW), 8-level balance scale, Timed-Up-and-Go (TUG), and 7-m habitual gait speed were used to estimate concurrent validity, examined by Spearman correlation coefficient (ρ). Inter- and intrarater reliability were calculated as Intra-class-correlations (ICC), and internal consistency by Cronbach alpha and item-total correlations (ρ). Ceiling effects were determined by obtaining the percentage of participants reaching the highest possible score. Results: The CBM significantly correlated with the FAB (ρ = 0.75; p < .001), 3MTW errors (ρ = − 0.61; p < .001), 3MTW time (ρ = − 0.35; p = .05), the 8-level balance scale (ρ = 0.35; p < .05), the TUG (ρ = − 0.42; p < .01), and 7-m habitual gait speed (ρ = 0.46, p < .001). Inter- (ICC2,k = 0.97), intrarater reliability (ICC3,k = 1.00) were excellent, and internal consistency (α = 0.88; ρ = 0.28–0.81) was good to satisfactory. The CBM did not show ceiling effects in contrast to other scales. Conclusions: Concurrent validity of the CBM was good when compared to the FAB and moderate to good when compared to other measures of balance and mobility. Based on this study, the CBM can be recommended to measure balance and mobility performance in the specific population of young-older adults. Trial registration Trial number: ISRCTN37750605 .

Cancer Treatment and Bone Health

Considerable advances in oncology over recent decades have led to improved survival, while raising concerns about long-term consequences of anticancer treatments. In patients with breast or prostate malignancies, bone health is a major issue due to the high risk of bone metastases and the frequent prolonged use of hormone therapies that alter physiological bone turnover, leading to increased fracture risk. Thus, the onset of cancer treatment-induced bone loss (CTIBL) should be considered by clinicians and recent guidelines should be routinely applied to these patients. In particular, baseline and periodic follow-up evaluations of bone health parameters enable the identification of patients at high risk of osteoporosis and fractures, which can be prevented by the use of bone-targeting agents (BTAs), calcium and vitamin D supplementation and modifications of lifestyle. This review will focus upon the pathophysiology of breast and prostate cancer treatment-induced bone loss and the most recent evidence about effective preventive and therapeutic strategies
