Kolesterol berkaitan erat dengan kejadian penyakit jantung koroner atau PJK. Kolesterol yang terlalu banyak di dalam pembuluh darah akan menyebabkan akumulasi plak kolesterol atau sering disebut aterosklerosis. Pemeriksaan kolesterol lengkap yang meliputi low density lipoprotein (LDL), high density lipoprotein (HDL), trigliserida, dan kolesterol total dapat memberikan gambaran atau prediktor resiko PJK dengan menggunakan rumus indeks Castelli dan Indeks aterogenik plasma (IAP). Pemeriksaan kolesterol lengkap dilaksanakan bekerja sama dengan Kader Posyandu, Bidan Desa, dan Perangkat Desa dengan jumlah responden sebanyak 48 orang yang terdiri dari 40 perempuan dan laki-laki sebanyak 8 orang. Hasil pemeriksaan menunjukkan bahwa resiko PJK dengan menggunakan indeks Castelli sebagian besar warga memiliki resiko rendah sebanyak 69% dibanding resiko sedang 27% dan resiko tinggi sebanyak 4 %. Sedangkan dengan menggunakan IAP, menunjukkan bahwa sebagian besar mengalami resiko tinggi PJK sebanyak 38%, resiko sedang 52%, dan resiko rendah hanya mencapai 10%. Kegiatan ini diharapkan menjadi bahan evaluasi bagi warga agar lebih memperhatikan pola makan yang dapat meningkatkan resiko terjadinya PJK, dengan mengurangi makanan-makanan yang mengandung kolesterol yang tinggi

This article explores the political and fiscal circumstances surrounding the demise of the distributor Leo-Film AG of Munich between 1933 and 1935. It shows how Leo-Film, a company closely associated with the Catholic Church, and which had borrowed heavily to sustain its activities during the period of the transition to sound, was brought down due to a Nazi ‘show trial’ that did great damage to the reputation and standing of the Catholic Church in Germany. The historical actors involved in the demise of Leo-Film include several important individuals who later became significant in the Nazi regime as well in the opposition to it.

Lithiated polysilane was synthesized by the mechanochemical reaction of layered polysilane with metallic lithium. The resulting dark green powder formed a Si-Li bond on the surface and demonstrated electroconductivity.

ABSTRACTDye type solar cells, especially those incorporating low cost dyes suffer from a very narrow photo-response wavelength range. Motivated by natural photosynthesis research, energy relay dyes (ERDs) appear to offer a possibility to broaden the dye-cell spectral response. In-turn photovoltaic cells can be an extremely sensitive tool for investigation of dye ERD photochemistry. Sensitive Chlorophyll based dye-type solar cells were prepared from purified natural Chlorophyll A. The importance of Chlorophyll purity is discussed as well as the use of purified Chlorophyll A in combination with ERD’s. . Results shed light on many interesting phenomenon including the nature of purified Chlorophyll A excitation and absorption. Importantly, it was found by this work that the ERD architecture when combined with a photosensitizer do not appear to having greater absorption in the infrared region of the spectrum than the ERD alone indicating a lack of cooperative absorption.

Hydraulic conductivity is of central importance in modelling both saturated and unsaturated flow in porous media. This is because it is central to Darcy's Law governing flow velocity and Richards' equation that is often used as the governing partial differential equation (PDE) for unsaturated flow. When doing numerical modelling of groundwater flow, two dominant challenges regarding hydraulic conductivity are heterogeneous media and unsaturated flow.

Low seed germination percentages have been reported for red huckleberry ( Vaccinium parvifolium Smith). Attempts to improve germination percentages and the speed of germination for red huckleberry are described. Red huckleberry seeds from two collection sites were given gibberellic acid potassium salt (GA-K) treatments (0, 500, 1000, and 1500 mg·L −1 ) and were germinated under three temperature regimens [constant 22 °C, 22 °C day/5 °C night (22/5 °C), and 20 °C day/13 °C night (20/13 °C) with a 12-h photoperiod]. A logistic regression model was used to assess the effects of temperature regimens and GA-K treatments on the maximum cumulative germination percentages, rates of increase, and germination lag times. For seeds untreated with GA-K, the 20/13 °C temperature regime resulted in germination percentages ranging from 30% to 61% and lag times (i.e., time to reach one-half of the maximum cumulative germination percentage) of 29 to 35 d for the two accessions. In comparison, the 22/5 °C temperature regime produced germination percentages of 12% and 38% and lag times of 38 to 64 d. The 22 °C constant temperature produced germination percentages ≤1%. Maximum germination percentages of up to 75% were obtained with 1500 mg/L GA-K. Rates of germination were generally unaffected by GA-K treatments, and germination lag times were reduced by an average of 10 d when compared with without GA-K. Improved germination percentages and reduced lag times for red huckleberry seeds were obtained by using a 20/13 °C temperature regime and 1000 to 1500 mg·L −1 GA-K.

lack currants (Ribes nigrum L.) and red and white currants (R. rubrum L., synonym = R. vulgare Jancz., R. sativum Syme.) are little known crops in the United States but are economically significant in Russia, Poland, Germany, Scandinavia, Great Britain, New Zealand, and many eastern European countries (Fig. The nutritious fruit of these plants are rich sources of antioxidants (such as vitamin C), phenolics, and flavenoids. Some of these fruit are eaten fresh, while others are processed into juices, jams, jellies, bakery, and dairy products. Currants have great potential for expansion into American juice and fruit markets.

Five atmospheric transport models were evaluated for use in Phase I1 ofthe Historical Public Exposures Studies at the Rocky Flats Plant. Models included a simple straight‐line Gaussian plume model (ISCST2), several integrated puff models (RATCHET, TRIAD, and INPUFF2), and a complex terrain mode (TRAC). Evaluations were based on how well model predictions compared with sulfur hexafluoride tracer measurements taken in the vicinity of Rocky Flats in February 1991. Twelve separate tracer experiments were conducted, eac lasting 9 hr and measured at 140 samplers in arcs 8 and 16 km from the release point at Rocky Flats. Four modeling objectives were defined based on the endpoints of the overall study: (1) the unpaired maximum hourly average concentration, (2) paired time‐averaged concentration, (3) unpaired time‐averaged concentration, and (4) arc‐integrated concentration. Performance measures were used to evaluate models and focused on the geometric mean and standard deviation of the predicted‐to‐observed ratio and the correlation coefficient between predicted and observed concentrations. No one model consistently outperformed the others in all modeling objectives and performance measures. About 75% of the maximum hourly concentration predictions were within a factor of 5 of the observations. About 64% of the paired and 80% of the unpaired time‐averaged model predictions were within a factor of 5 of theobservations. The overall performance of the RATCHET model was somewhat better than the other models. All models appeared to experience difficulty defining plume trajectories, which was attributed to the influence of multilayered flow initiated by terrain complexities and the diurnal flow patterns characteristic of the Colorado Front Range.
