Significantly increasing consumption and demand in conventional fossil energy sources require to be more efficient sustainable. In this study, it is aimed increase the efficiency of systems by using thermodynamic cycles from waste heat sources. The designed system at adding sub-cycles a gas turbine. results analyzed with engineering equation solver program, when all are combined, 75% total exer...

A two-year follow-up study of progestogen-only contraception with chlormadinone acetate indicates no increase of the level of factors VII and X, as found after three cycles with all oestrogen-progestogen oral contraceptives. Clotting factors which were raised with combined preparations became normal after the sixth monthly cycle of progestogen and remained normal during the two-year period of s...

Influence of formation of surface nano/ultrafine structure using deep rolling on plasma nitriding and tribological properties of the AISI 316L stainless steel was investigated. Initially, the deep rolling process was carried out on the bar-shaped specimens at 15 cycles with 0.2 mm/s longitudinal rate and 22.4 rpm bar rotation. Then, plasma nitriding treatment was applied on the as-received...

Snowshoe hare populations in the boreal forests of North America go through 10-year cycles. Supplemental food and mammalian predator abundance were manipulated in a factorial design on 1-square-kilometer areas for 8 years in the Yukon. Two blocks of forest were fertilized to test for nutrient effects. Predator exclosure doubled and food addition tripled hare density during the cyclic peak and d...

We propose new forecast combination schemes for predicting turning points of business cycles. The combination schemes deal with the forecasting performance of a given set of models and possibly providing better turning point predictions. We consider turning point predictions generated by autoregressive (AR) and Markov-Switching AR models, which are commonly used for business cycle analysis. In ...

Mantle cell lymphoma (MCL) is a rare malignant lymphoma of the gastrointestinal (GI) tract that may present as multiple lymphomatous polyposis (MLP); however, MLP with intussusception is rarely reported in MCL. In the present study, a 54-year-old male patient was diagnosed with MCL, presenting with numerous polypoid lesions of the complete GI tract combined with ileocecal intussusception. Right...

Facular emission is one of the major contributors to long-term solar irradiance variations. Reconstructions of past facular variations, however, are strongly hampered by the lack of reliable proxies, particularly on time-scales longer than a solar cycle. We consider the five potential facular proxies with records covering more than 40 years. By suitably weighting and combining them we create a ...
