The need for electrical energy in Nehibe village is currently increasing along with the increase population and new households. demand electricity this reaches 18 kW, an average power per household of 450 VA. problem that Hachakwa Micro Hydro Power Plant (PLTMH), which very close to village, has a capacity only 10 kW. Based on problem, study aims design peltor turbine two nozzles 26 kW PLTMH. T...

Dendritic spines of rat neostriatal neurons were examined by light microscopy and high voltage stereo electron microscopy (HVEM) following selective staining by intracellular microinjection of horseradish peroxidase. Conventionally prepared material also was used for quantitative analysis of dendritic spines from serial thin sections of neostriatum. Stereo electron microscopy of semithin sectio...

The morphology of the canine cardiac myosin molecule has been investigated in the electron microscope with Hall's mica-replica technique. The molecule is an elongated rod (shaft) of nonuniform diameter with a globular expansion (head) on one end. Statistical analysis of the lengths of 1908 molecules showed that the mean length was 1610 +/- 250 A; the mean length of the head was 210 +/- 20 A; an...

The diameter of a connected graph $G$, denoted by $diam(G)$, is the maximum distance between any pair of vertices of $G$. Let $L(G)$ be the line graph of $G$. We establish necessary and sufficient conditions under which for a given integer $k geq 2$, $diam(L(G)) leq k$.

BACKGROUND Many studies have emphasized on fetal pinna measurements and morphologic features to use this structure as an additional marker for fetal chromosomal anomaly. OBJECTIVES To assess relationship between fetal pinna length and gestation age and develop a nomogram. To assess relationship between fetal pinna length and head circumference and biparietal diameter. METHODS Fetal pinna me...

BACKGROUND Even if the benefits of collars are unclear, they remain widely used, in several femoral stem designs. This study aimed to determine whether collar size should be proportional to hip dimensions and morphology. The hypothesis was that the collar should be larger for greater stem sizes and for varus femoral necks. METHODS Computed Tomography scans of 204 healthy hips were digitally a...

Abstract This paper presents an experimental study of abrasive waterjet turning extrusion aluminum alloy (AlMg0,7Si). The aim the is to determine differences two methods from point view machined surface quality and depth penetration, i.e., diameter parts after process. During experiments, traverse speed cutting head rotation turned were changed, other parameters, like pressure water, mass flow ...

Lipomatous tumors originate from adipocytes, and represent the largest group of mesenchymal tumors. Lipomas are most likely under reported due to their insidious growth. About 13% of lipomas occur in the head and neck region. When they occur in the maxillofacial region, it is likely for the patients to be referred to the hospital for aesthetical reasons. In this multicenter study, data such as ...

PURPOSE This study investigated the shape of bone grafts and associations with upper limb function over the long term after free vascularized fibular head graft (FVFHG) for reconstruction of the proximal humerus after wide resection for bone sarcoma. METHODS Patients comprised 3 women who had undergone FVFHG at least 5 years previously. Age at surgery was 12 years in 2 cases and 76 years in o...
