Karyology and agar analysis of the agarophyteGelidiella acerosa (Forsskål) Feldmannet Hamel from the Philippines

Abstract: Microspectrophotometry with the DNA-localizing fluorochrome DAPI demonstrated ploidy level differences in tetrasporophytic and presumptive gametophytic phases ofGelidiella acerosa from the Philippines. Comparison of mean nuclear DNA (If) values to chicken erythrocytes (RBC) resulted in an estimate of 0.32 pg/2 C genome. Karyological studies with aceto-orcein revealed a chromosome complement of six bivalents during diakinesis of tetrasporocytes. The agar yield ranges from 13–24% dry weight, depending on the method of extraction. Agar extraction in 1 N NaOH resulted in an increased gel strength of 189 g cm−2 at 1.5% concentration. Infrared spectroscopy indicated a relatively high sulfate content in native agar. The low (61 °) melting temperature is indicative of high sulfation and small molecular size.

Electrocatalytic oxygen evolution reaction of hierarchical micro/nanostructured mixed transition cobalt oxide in alkaline medium

Abstract: In this work, different cobalt-based mixed transition metal oxides (MTMOs) were fabricated by hydrothermal process followed by calcination. Doping Co3O4 with other transition metals, such as Ni, Cu, and Mn, resulted in a fascinating morphological transformation from quasi-spherical nanoparticles to hierarchical micro/nanostructures. Hollow urchin-like NiCo2O4 exhibited a high specific surface area which led to excellent electrochemical performance towards oxygen evolution reaction (OER). It achieved a low overpotential of about 309 mV at 10 mA/cm2 current density, which is comparable to other reported electrocatalysts. Cyclic voltammetry (CV) technique revealed the redox processes that occur on the surface of NiCo2O4 and supported that Co4+ could be the active center during electrocatalysis. In general, the excellent electrocatalytic activity, stability, and reversibility of NiCo2O4 in alkaline condition suggest its applicability as an OER electrocatalyst.

Factors Influencing the Choice of Location: Local and Foreign Firms in the Philippines

Abstract: HERRIN A. N. and PERNIA E. M. (1987) Factors influencing the choice of location: local and foreign firms in the Philippines, Reg. Studies 21, 531–541. The paper addresses the following questions. Is the locational behaviour of foreign firms systematically different from that of local enterprises? What are the more important determinants of industrial location, in general, and by specific types of firms? How effective are direct government influences in the choice of location? This analysis is based on data from a survey of 100 firms drawn from the top 1,000 corporations in the Philippines. The overall finding is that out of thirty-four factors that are commonly thought to influence location decision, only seven are considered as crucial. These determinants can be distilled into four, namely, access and transport, power, information and communication, and physical plant requirements. On the whole, they apply more or less equally to local and foreign firms, implying that there is little difference in their ...

The new DTPw-HBV-Hib combination vaccine can be used at the who schedule with a monovalent dose of hepatitis B vaccine at birth.

Abstract: An open, randomized, clinical trial was conducted in order to assess the reactogenicity and immunogenicity of DTPw-HBV and Haemophilus influenzae type b (Hib) vaccines when given either as a mixed administration or as separate concomitant injections using the WHO schedule at 6, 10 and 14 weeks of age, following a dose of HBV at birth. There were no clinically relevant differences in the immune response to any component between the mixed and separate administrations. In fact the anti-tetanus GMTs were significantly higher (p=0.002) in mixed administration (3.9 IU/ml) compared with the separate administration (1.9 IU/ml). However although all subjects achieved anti-PRP titers > or = 0.15 microg/ml, higher anti-PRP GMTs were seen in the group receiving the separate administration. Importantly, the addition of Hib did not adversely alter the reactogenicity profile of DTPw-HBV. This report which demonstrates that this novel combination can be used in WHO recommended schedule.
