Morphogenesis, the development of shape or form in cells or organisms, is a fundamental but poorly understood process throughout biology. In the bacterial domain, cells have a wide range of characteristic shapes, including rods, cocci, and spirals. The cell wall, composed of a simple meshwork of long glycan strands crosslinked by short peptides (peptidoglycan, PG) and anionic cell wall polymers...

The objective of this experiment was to investigate the effects of different levels of alfalfa hay (AH) and sodium propionate (Pro) added to starter diets of Holstein calves on growth performance, rumen fermentation characteristics, and rumen development. Forty-two male Holstein calves (40±2kg of birth weight) were used in a complete randomized design with a 3×2 factorial arrangement of treatme...

Abstract To explore the optimization seismic design of frame-multi-ribbed composite wall structure, firstly finite element model a six story structure is established based on software SAP2000. Secondly critical parameters multi under action are analysised using analysis software. Finally response different rib combinations and optimal arrangement rule studied. The results reveals that lateral s...

From the perspective of technical suitability, this paper comparatively analyzed economical thickness and suitable exterior wall thermal insulation material with highest energy saving rate building envelop, attained relationship, curves, model material. The purpose is to provide useful evidences for residential buildings optimization design wall, so that architectural designers could be inspire...

background and objective: mediastinal masses in children are a heterogenous group of asymptomatic potentially life-threatening congenital, infectious, or neoplastic lesions that present complex diagnostic and therapeutic dilemmas. materials and methods: the clinical and laboratory features of 65 patients who had open biopsies in ali-asghar hospital over 11 years were reviewed. results: seventy-...

osteosarcoma (osteogenic sarcoma: os) is the most common primary malignant bone tumor of long bones, whereas primary osteosarcoma of chest wall, especially in sternum, is extremely rare. we report a 57-year-old man with an immobile slow growing mass located in the middle of the sternum. the patient had no significant pain or tenderness and the past medical history was not remarkable. ct-scan sh...

BACKGROUND The presence of the G-spot (an assumed erotic sensitive area in the anterior wall of the vagina) remains controversial. We explored the histomorphological basis of the G-spot. METHODS Biopsies were drawn from a 12 o'clock direction in the distal- and proximal-third areas of the anterior vagina of 32 Chinese subjects. The total number of protein gene product 9.5-immunoreactive nerve...

A systematic way to derive the conserved quantities for the axisymmetric liquid jet, free jet and wall jet using conservation laws is presented. The flow in axisymmetric jets is governed by Prandtl’s momentum boundary layer equation and the continuity equation. The multiplier approach is used to construct a basis of conserved vectors for the system of two partial differential equations for the ...
