Biocompatible calcium phosphate ceramic grafts are able of supporting new bone formation in appropriate environment. The major limitation of these materials usage for medical implants is the absence of accessible methods for their patient-specific fabrication. 3D printing methodology is an excellent approach to overcome the limitation supporting effective and fast fabrication of individual comp...

This research examined the impact of One-Child Policy (OCP) on Chinese human capital per capita. To best this author’s knowledge, is first to explore effect OCP by using propensity score matching (PSM). also relationship between gender difference in capita with implementation OCP. It was found that has a positive not only improving capital, but decreasing capital. These results confirm existenc...

Melasma is a common acquired hypermelanosis of the skin that has been associated with several etiologic factors including ultraviolet light exposure, pregnancy, and oral contraceptives (OCPs) (1). Forty-one percent of women surveyed in one study had onset of melasma after pregnancy, and 25% after starting an OCP (2). Women who develop melasma during pregnancy may be more susceptible to developi...

In this article, we discuss fractional order optimal control problems (FOCPs) and their solutions by means of rational approximation. The methodology developed here allows us to solve a very large class of FOCPs (linear/nonlinear, time-invariant/time-variant, SISO/MIMO, state/input constrained, free terminal conditions etc.) by converting them into a general, rational form of optimal control pr...

A well–known problem in indirect optimal control is to find a suitable initial guess for the adjoint states which is sufficiently close to the optimal solution. This paper presents a new homotopy approach to overcome this problem by deriving an auxiliary optimal control problem (OCP) for which the adjoint states are simply zero. A continuation method is employed to smoothly reach the original O...

BACKGROUND Cerebral venous sinus thrombosis is a rare and potentially life-threatening neurologic manifestation of antiphospholipid syndrome. Oral contraceptive pills (OCP) may increase the risk of vascular events, even in people without family history of venous thrombosis. CASE PRESENTATION A 31-year-old woman with four weeks of constant headache and history of taking OCP for one year has be...

Calcium phosphate (Ca-P) coatings on zirconia bone implants have a great potential to improve the osseointegration of already existing ceramic implants, owing to their bone-bonding ability and high osteoconductive characteristics. In our study, we have prepared three different kinds of Ca-P coatings, namely the octacalcium phosphate (OCP), hydroxyapatite (HAp) and β-tricalcium phosphate (β-TCP)...

As part of the WHO Onchocerciasis Control Programme in West Africa (OCP), the attack phase of operations in the Niger basin in Guinea began in 1989 with the simultaneous use of ivermectin and vector control. Larvicide applications coupled with annual large-scale ivermectin distribution have greatly reduced blackfly infectivity (by 78.8% for the number of infective larvae per 1000 parous flies)....

Mental variables are central to symbolic accounts of cognition. Conversely, according to the pattern associator hypothesis, variables are obsolete. We examine the representation of variables by investigating the Obligatory Contour Principle (OCP, McCarthy, 1986) in Hebrew. The OCP constrains gemination in Hebrew roots. Gemination is well formed at the root's end (e.g., SMM), but not in its begi...
