Comparative study of the proximate composition of pyxicephalus adspersus and oreochromis niloticus from nigerian wetland A study was conducted to evaluate the carbohydrate, lipid, ash, protein, moisture and fiber contents of samples of African bullfrog (Pyxicephalus adspersus) and tilapia (Oreochromis niloticus) collected from ARAC, Aluu, Port Harcourt, Nigeria from Novenber 2013 – February Lead (Pb) concentration was assessed of the arable soils in the vicinity of mining and dumping sites in Nigeria. Its contents in the arable soils assayed by means of atomic absorption spectrophotometry, (AAS) ranged from 6.8 – 47.8 mg/kg. The enrichment factor

Nigeria

The Nigerian health care system is continuously faced with a shortage of doctors known as 'brain drain', because of emigration by skilled Nigerian doctors to North America and Europe. In 1995, it was estimated that 21,000 Nigerian doctors were practising in the United States alone, which is about the same as the number of doctors working in the Nigerian public service.

Lukin and his team cooled rubidium atoms in a vacuum chamber slightly above absolute zero temperature at which particles do not move. They fired at the cloud and found it did pass through it and exit individually, but only to emerge as single molecule to the other side.

Lithium in younger granites of Northern Nigeria

The Nigerian Younger Granites often contain unusually high concentrations of such elements as rubidium (BuTi^EBefa, 1962), gallium (BOWDEN, 1964), zirconium, niobium and yttrium (BUTLEB and SMITH, 1962) that normally accumulate in pegma- tites

Egenskaper Rubidium er et mykt slvhvitt alkalimetall som lett oksiderer (og kan selvantenne) i luft, og som har et lavt smeltepunkt p 39,3 C.Det reagerer voldsomt med vann, og i likhet med kalium og cesium er reaksjonenen kraftig nok til kunne antenne frigjort hydrogen.

Association Round Table 1169 structure of the crust. As the data are geographically oriented and in digital format, standard image-processing and analysis techniques can be applied. For instance, we have used a spatial filtering tech nique to interpolate between

The percentage elemental composition of soil around the mining vicinity unveiled the presence of Radionuclides K-40, Rubidium and Thorium in the soil. This is of great concern. The XRD mineralogical investigation of Columbite shows the presence of associated braunite, cassiterite, ilmenite, quartz, and zircon while the phase pattern for Tin ore confirmed the availability of cassiterite

Rubidium is a very soft, silvery-white metal in the alkali metal group. Rubidium metal shares similarities to potassium metal and caesium metal in physical appearance, softness and conductivity. Rubidium cannot be stored under atmospheric oxygen, as a highly exothermic reaction will ensue, sometimes even resulting in the metal catching fire.

Study of coir reinforced laterite blocks for buildings

Rubidium, Rb or Cesium, Cs. At ordinary temperatures and pressure below 100 mm mercury, Potassium peroxide combines with oxygen to give the sesquioxides, K 2 O 3. Study of laterite shows that laterite contains hydrated aluminum and iron oxides and

Rubidium-Potassium In any co-magmatic series, R b correlates well with K. This is seen for the gabbro-syenite-monzonite rocks found in the Nigerian complexes. Tangential to this trend are the peralkaline and peraluminous granitoids in which R b shows wide variation for little o r n o change in K 2 0 (Figure 7 ) .
