Adjustment of the basin-scale circulation at 26 degrees N to variations in Gulf Stream, deep western boundary current and Ekman transports as observed by the Rapid array

The Rapid instrument array across the Atlantic Ocean along 26 degrees N provides unprecedented monitoring of the basin-scale circulation. A unique feature of the Rapid array is the combination of full-depth moorings with instruments measuring temperature, salinity, pressure time series at many depths with co-located bottom pressure measurements so that dynamic pressure can be measured from surface to bottom. Bottom pressure measurements show a zonally uniform rise (and fall) of bottom pressure of 0.015 dbar on a 5 to 10 day time scale, suggesting that the Atlantic basin is filling and draining on a short time scale. After removing the zonally uniform bottom pressure fluctuations, bottom pressure variations at 4000 m depth against the western boundary compensate instantaneously for baroclinic fluctuations in the strength and structure of the deep western boundary current so there is no basin-scale mass imbalance resulting from variations in the deep western boundary current. After removing the mass compensating bottom pressure, residual bottom pressure fluctuations at the western boundary just east of the Bahamas balance variations in Gulf Stream transport. Again the compensation appears to be especially confined close to the western boundary. Thus, fluctuations in either Gulf Stream or deep western boundary current transports are compensated in a depth independent (barotropic) manner very close to the continental slope off the Bahamas. In contrast, compensation for variations in wind-driven surface Ekman transport appears to involve fluctuations in both western basin and eastern basin bottom pressures, though the bottom pressure difference fluctuations appear to be a factor of 3 too large, perhaps due to an inability to resolve small bottom pressure fluctuations after removal of larger zonal average, baroclinic, and Gulf Stream pressure components. For 4 tall moorings where time series dynamic height (geostrophic pressure) profiles can be estimated from sea surface to ocean bottom and bottom pressure can be added, there is no general correlation between surface dynamic height and bottom pressure. Dynamic height on each mooring is strongly correlated with sea surface height from satellite observations and the variability in both dynamic height and satellite sea surface height decrease sharply as the western boundary is approached

Peran Dewan Pengawas Syariah dalam Melakukan Pengawasan terhadap Pelaksanaan Akad pada Lembaga Pembiayaan Syariah (Studi terhadap Fif Syariah Cabang Pontianak)

Federal International Finance Sharia (FIF Sharia) is a one of non-Islamic financial institutions which form of Limited Liability Company and in accordance with applicable regulations FIF Sharia is also have the Sharia Supervisory Board as well as the completeness of its operations to ensure the performance of Islamic finance company is run in accordance with Islamic principles . To view and to determine the extent the performance of the Sharia Supervisory Board in overseeing the implementation of the agreement in FIF Syaraiah, it is necessary to research on "SHARIA SUPERVISORY BOARD ROLE IN TAKING CONTROL OF IMPLEMENTATION OF ISLAMIC FINANCING INSTITUTIONS Akad (FIF Against Sharia Studies Branch Pontianak)".Two issues raised is how the role and what barriers Sharia Supervisory Board in monitoring the implementation of the agreement on financial institutions FIF Syariah.This study is specifically aimed to reveal and analyze the role and function of the Sharia Supervisory Board as well as to identify factors inhibiting the Sharia Supervisory Board in overseeing the implementation of the agreement on financial institutions FIF Sharia.The research method uses yuridical emperical, ie the method used to solve legal problems through secondary data first, then proceed to conduct primary research on the data by field research.The results of research on the role of the Sharia Supervisory Board in monitoring the implementation of the agreement on financial institutions FIF Sharia Branch Pontianak, that the Sharia Supervisory Board has been instrumental in monitoring the implementation of the agreement on the financing institutions FIF Sharia but supervision carried Sharia Supervisory Board is still less than optimal because only indirect supervision by studying the reports alone. Sharia Supervisory Board never went to the field as a result of the Sharia Supervisory Board can not monitor the actual implementation of the agreement on the ground.The obstacles faced by the Board in monitoring the implementation of the agreement on financial institutions FIF Sharia is, more due to the Sharia Supervisory Board personnel who have concurrent positions in several Islamic financial institutions, a very limited number of personnel and is in the central office, as well as the quality of the source human Sharia Supervisory Board and other devices are less understanding of Islamic economics because it is not derived from the sharia economic academia.2Increasing the role of the Sharia Supervisory Board should continue to be done and not merely perform monitoring tasks but also able to become an advisor in developing existing products FIF Sharia branch in Pontianak and regulations related parties of course is expected to facilitate the Sharia Supervisory Board in minimizing obstacles to supervise the implementation of the agreement in FIF Shari

Oil Palm Empty Bunches Bioconversion Using Trichoderma sp. and Black Soldier Fly Larvae As Poultry Feed Composition

Empty Fruit Bunches (EFB) is palm oil industry waste which has very large volume compared with another commodity of agro-industry waste in Indonesia. Trichoderma sp. and Larva Black Soldier Fly (BSF) with bioconversion method can be used as probelem resolve of EFB. The EFB material was obtained from Palm Oil Factory in Banten. EFB was researched in Indonesian Ornamental Fish Culture Research Institute in Depok and the result test was taken at the Laboratory of Animal Science and Technology of Bogor Agricultural University. The percentage of Trichoderma sp. fermentation (5%, 10% and 20% ) affected EFB palatability of BSF larvae and the fermented EFB with 10 % of Trichoderma sp. has a feasibility to be used as medium of BSF larvae with yield of 73.28 gram on day 4 th from the initial weight of mini larvae BSF 5 grams. At the bioconversion stage using BSF larvae with a dose of 10% Trichoderma sp. (5 gram, 15 gram and 25 gram) was obtained significant result on the initial weight of mini larvae 5 gram to 230.34 gram from fermented EFB weight of 550 gram on day 8th  , so that the average yield of average larvae was obtained By 39%. Result of proximate test of larvae on dry condition 100% obtained crude protein content (PK) 35.40 - 42.31% and crude fats (LK) 3.33 – 36.41%. Therefore, by using this test result, it will be possible to be used as poultry feed ingredient candidate in the future

Socioeconomic position, John Henryism, and incidence of acute myocardial infarction in Finnish men

Previous cross-sectional studies examining whether John Henryism (JH), or high-effort coping with socioeconomic adversity, potentiates the inverse association between socioeconomic position (SEP) and cardiovascular health have focused mainly on hypertension in African Americans. We conducted the first longitudinal test of this hypothesis on incident acute myocardial infarction (AMI) using data from the Kuopio Ischemic Heart Disease Risk Factor Study in Finland (N = 1405 men, 42-60 years). We hypothesized that the expected inverse gradient between SEP and AMI risk would be stronger for men scoring high on JH than for those scoring low. John Henryism was measured by a Finnish version of the JH Scale for Active Coping. Four different measures of SEP were used: childhood SEP, education, income, and occupation. AMI hazard ratios (HR) by SEP and JH were estimated using COX proportional hazard models, before and after adjustment for study covariates. 205 cases of AMI occurred over a median of 14.9 years. Men employed in lower rank (farmer, blue-collar) occupations who scored high on JH had significantly higher age-adjusted risks of AMI than men in higher rank (white-collar) occupations (HR = 3.14, 95% CI: 1.65-5.98 for blue collar; HR = 2.33, 95% Cl: 1.04-5.22 for farmers) who also scored high on JH. No socioeconomic differences in AMI were observed for men who scored low on JH (HR = 136, 95% CI: 0.74 2.47 for blue collar; HR = 0.93, 95% CI: 0.59-1.48 for farmers; p = 0.002 for the SEP x JH interaction). These findings persisted after adjustment for sociodemographic, behavioral, and biological factors. Results for other SEP measures were in the same direction, but did not reach statistical significance. Repetitive high-effort coping with adversity (John Henryism) was independently associated with increased risk for AMI in Finnish men, underscoring the potential relevance of the John Henryism hypothesis to CVD outcomes other than hypertension and to populations other than African Americans.
