The calculated results agree well withpractice, showing that this principle is a reliable basis for determination of the struc-tural units for some binary metallic melts.展开更多

Planning schemes of New Pingdi and Xiangyunzhuang Village were analyzed from six perspectives: selection of new village site, planning structure, planned road, architectural layout, public facilities and landscape design. It was then proposed that "village relocation and annexation" could not only save investment in public infrastructure, but also improve land use efficiency, thus it was an important approach of optimizing distribution of land resources.展开更多

The calculated results agree with practice and obey the mass action law, showing that the models formulated can reflect the structural characteristics of both melts. Meanwhile, it confirms that annexation principle is applicable to the Ag-Bi-In metallic melts. The melts involving eulectic which give rise to phase separation, and in which activities exhibit positive deviation from Raoult's law is the basic cause of melts transforming from homogeneous to heterogeneous ones.展开更多

The methodology of the work started with the collection of steel samples from various active building project sites in four different towns viz: Bamenda, Douala, Maroua and Yaoundé and testing their tensile strength and elongation using a Universal Testing Machine and also carrying out the bending test. Results show that bars without marked manufacturer’s name fell all the tests. Other results show that 52% of all the steel had yield stresses below 400 Mpa and the highest deviation in the yield strengths was 22.50%. The study recommends that properly marked grade 500 steel bars should be adopted in the Cameroon national annex to Eurocode 2.展开更多

This structure is not used in Modem Standard Arabic. It was introduced into the Arabic dialects later on as a competing structure to the Construct State （CS）. First, we discuss the characteristics of this structure in comparison to its counterpart： the CS. we show that semantically FS can express only three semantic relations out of the five semantic relations CS can convey. Furthermore, the paper shows that the FS genitive exponent in HA ＂hagg＂ agrees with the head noun of the matrix DP in phi-features. The discussion then shifts to the origin of the genitive exponent hagg. The paper argues that it is originally a noun that has acquired a new meaning： an anaphor that means something like ＂one of＂. Hence, we gloss hagg as ANAPH. Contrary to previous analyses for the FS genitive exponent, the paper proposes that hagg, the noun, heads its own CS and it is linked to the preceding DP by a binding relationship, which involves feature agreement in gender and number. Consequently, we propose that hagg-headed CS has the same structure of the nominal CS. Finally, we investigate the occurrence of both FS and CS structures in HA and show when one structure is preferred to the other.展开更多

In addition, extended operation of the diesel generator at partial load develops the condensation of combustion residues on the engine cylinder walls, which, after a certain time, increases friction, reduces the efficiency of the equipment and increases its fuel consumption. On the other hand, recent regulatory changes have led to ever more stringent and evolving emission standards. Among these, the International Maritime Organization (IMO) and the Environmental Protection Agency (EPA) have implemented emission standards in order to reduce exhaust gas emitted by marine diesel engines. To phase lower emission engines as soon as possible, a Tier system was adopted. This paper presents a literature review of existing technologies available to optimize the energy performance of diesel engines and diesel generators in order to reduce the cost of electricity, to increase the diesel engine efficiency and to decrease their fuel consumption and greenhouse gases (GHG) emissions. The proposed optimization methodologies are based on the application of Pre-treatment, Internal treatment and Post-treatment technologies for diesel engines and on the application of mechanical and electrical technologies for diesel power generators (DPGs). The list of references given at the end of the paper should offer aids for students and researchers working in this field.展开更多

Rabbits and rats were given Annexin32 by intravenous administration. Then Kaolin partial thromboplastin time (KPTT), thrombosis in vitro and in vivo were assayed. The results showed that KPTT of rabbits was prolonged (p < 0.01), and the length and weight of thrombus in vitro were reduced (p < 0.01) after administration of Annexin32 at 1 mg/kg. It also inhibited thrombosis in vivo and reduced the weight of venous thrombus significantly in rats (p < 0.01). All these results suggested that Annexin32 possesses the characteristic of antithrombotic effect and fewer side effects on coagulation time.展开更多
