A Wilkinson Power Divider with Harmonic Suppression and Size Reduction using High-low Impedance Resonator Cells

A miniaturized Wilkinson power divider using high-low impedance resonator cells are designed and fabricated. The proposed power divider occupies 23.7% of the conventional structure circuit area at the operating frequency of 0.9 GHz and it is also able to suppress harmonics. According to the measured results at 0.9 GHz, the insertion-losses of output ports are 3.087 dB, the return-losses at all ports are more than 30 dB, and the isolation between output ports is better than 35 dB. Also, 2nd to 10th spurious frequencies are suppressed. According to the measured S11, when it is less than -15 dB (from 0.65 GHz to 1.1 GHz) the fractional bandwidth of the proposed structure is 50%. Good agreement between simulation and measured results is achieved

Peran Pemerintah dan Ulama dalam Pengelolaan Zakat dalam Rangka USAha Penanggulangan Kemiskinan dan Peningkatan Pendidikan di Indonesia

Abstak: Poverty is the worst conditions experienced by people that the appearance of it was not expected; even almost everyone wanted to avoid it. Adoption is not charity into the state system, causing the Islamic world lost the power to run welfare programs, to solve socioeconomic problems, such as poverty. In the teachings of Islam, Zakat in economics appears to be an alternative instrument for effective poverty reduction, which has many advantages over conventional fiscal instruments that now exist, if the current impact on economic activity is still relatively small, and then this is caused by several things. Spending a minimum expenditure of zakat is to create a more equitable distribution of income that not yet optimum (Necessary but not sufficient condition). Therefore, others expenses necessary to complete the expenditure of zakat such as sadaqah, waqaf and so on. so the impact on income distribution becomes more optimum. Besides the management of zakat which has not been well managed and professionally, as well as low public awareness to tithe correctly. For the role of government and clerics in the management of zakat in order to attempt to reduce poverty and improve education in Indonesia is required

Engineering Study on Oriflame Cosmetic

In this modern era are so many beauty products on the market ranging from legal and illegal, many also now servicing beauty clinics and doctors growing beauty with sophisticated tools. Oriflame became one of the beauty products that exist in Indonesia trying to offer products that are natural and provide business opportunities with cosmetic. Oriflamme cosmetic is one beauty product that is widely used in Indonesia because of this cosmetic can be used for all skin types especially for tropical areas such as material natural Indonesia.kosmetika from Sweden. Some ingredients of cosmetics Oriflame among blueberry, horse chestnut, yarrow, iris, palm, birch, cloudberry, apples and so forth. Oriflamme itself not only produce cosmetic to be marketed but Oriflame also provides land for business in Oriflame, so as a member of Oriflame not only able to use the product also can take advantage of the opportunity to become a career

Computation of Neutron Star Structure Using Modern Equation of State

Using the modern equations of state derived from microscopic calculations, we have calculated the neutron star structure. For the neutron star, we have obtained a minimum mass about $0.1 {\rm M_{\odot}}$ which is nearly independent of the equation of state, and a maximum mass between $1.47 {\rm M_{\odot}}$ and $1.98 {\rm M_{\odot}}$ which is strongly dependent on the equation of state. It is shown that among the equations of state of neutron star matter which we have used, the stiffest one leads to higher maximum mass and radius and lower central density. It is seen that the given maximum mass for the Reid-93 equation of state shows a good consistency with the accurate observations of radio pulsars. We have indicated that the thickness of neutron star crust is very small compared to the predicted neutron star radius.Comment: 16 pages, 6 figure

Integration of Pasturing Systems for Cattle Finishing Programs

A 3-year study, using 84 fall-born and 28 spring-born calves of similar genotypes, was conducted to integrate pasturing systems with drylot feeding systems. Calves were started on test following weaning in May and October. Seven treatments were imposed: 1) fall-born calves directly into feedlot; 2 and 3) fall-born calves put on pasture with or without ionophore and moved to the feedlot at the end of July; 4 and 5) fall-born calves put on pasture with or without ionophore and moved to the feedlot at the end of October; 6 and 7) spring-born calves put on pasture with or without ionophore and moved to the feedlot at the end of October. A bromegrass pasture consisting of 16 paddocks, each 1.7 acre in size, was available. Each treatment group had access to 1 paddock at a time and was rotated at approximately 3-day intervals. In the feedlot, steers were provided an 82% concentrate diet containing whole-shelled corn, ground alfalfa hay, and a protein, vitamin and mineral supplement containing ionophore and molasses. As pens of cattle reached about 1150 lb. average live weight, they were processed and carcass traits were evaluated. Pasture daily gains were highest for cattle on pasture for the longest duration (P \u3c .03), and overall daily gains were highest for drylot cattle (P \u3c .01) and decreased with increased time spent on pasture. Although differences among treatments existed in numerical scores for yield and quality grades (P \u3c .05 and P \u3c .03, respectively), all treatments provided average yield grade scores of 2 and quality grades of low Choice or higher. Use of four production costs and pricing scenarios revealed that fall-born calves placed on pasture for varying lengths of time were the most profitable (P \u3c .04) among the treatments. Furthermore, employing a 5% price sensitivity analysis, indicated that fed-cattle selling price had great impact on profit potential and was followed in importance by feeder purchase price and corn grain price. Overall, these findings should provide significant production alternatives for some segments of the cattle feeding industry and also lend substantial credence to the concept of sustainable agriculture
