Abstract The objective of the study is multi elemental analysis of four indigenous Ethiopian tuber crops using instrumental neutron activation analysis (INAA) technique in order to get scientific evidences about the status of essential, trace and non-essential elemental compositions. The samples were collected from Southern and South-western parts of Ethiopia. The irradiation and measurement were performed by using irradiation and counting facilities of the Nigeria Nuclear Reactor-1 (NIRR-1) and a HPGe detector setup at the Centre for Energy Research and Training (CERT), Ahmadu Bello University (ABU), Zaria, Nigeria. A total of 17 elements were determined at various concentration levels. The highest concentrations of K, Mg, Mn and Zn were found in Colocasia esculenta (L.) Schott, whereas; the concentrations of essential and trace elements; Ca, K, Mg, Na, Cl, Mn, and Zn were found to be high in the native Coccinia abyssinica (Lam.) Cogn tuber. The estimated daily intake values of the constituent elements from the consumption of these crops are below upper tolerable limits set by international organizations such as WHO and FAO.

This study was undertaken to estimate the contribution of meat and meat products consumption to the daily intakes of trace elements (Fe, Zn, Cu, Se), heme iron, and selected B vitamins (thiamine, riboflavin, niacin) in Italy. Meat and meat products were selected on the basis of their consumption frequency reported by the most recent nationwide dietary individual survey carried out in Italy (INN-CA study). The daily intakes of total iron and heme iron were 1.65 and 1.13 mg/person/day. Zinc intake was 3.65 mg/person/day. Beef made the main contribution to iron, heme iron, and zinc daily intakes. Copper daily intake was 107.3 mug/person/day, with meat products provided the highest contribution (40 mug/person/day). Daily intake of selenium (7.14 mug/person/day) was provided mainly by poultry consumption. Thiamine intake was 228 mug/person/day, and meat products were the main source (110 mug/person/day). Riboflavin intake was 136 mug/person/day, with both beef and meat products as the main contributors (40 mug/person/day). Niacin intake was 7.53 mg/person/day, and poultry was the main source (2.28 mg/person/day). Meat and meat products were a valuable source of micronutrients, supplying 47, 48, and 24% of zinc, niacin, and thiamin daily requirements, respectively, and over 10% of iron, copper, selenium, and riboflavin daily average requirement values of the italian RDAs calculated for the population involved in the survey (INN-CA study).

Minerals And Trace Elements

Background: Contamination of soil and agricultural products by heavy metals resulting from rapid industrial development has caused major concern. Dietary exposure to heavy metals has been associated with toxic and adverse health effects. The main threats to human health from heavy metals are associated with exposure to Pb, Cd and Hg. The aim of this study was to monitor the presence of heavy metals, minerals and trace elements in cereals consumed by Dhaka city residents. Methods: One hundred and sixty cereal samples were collected for eight (08) composited samples and analyzed for the determination of sixteen elements. Heavy metals were analyzed by Inductively Coupled Plasma Mass Spectrometry (ICP-MS), and other elements were determined by Atomic Absorption Spectrometry (AAS). Results: The average concentrations of elements in cereals fall within the safe limit except for Pb, Cr, Na and Mg, which exceeded the safe limits. The daily intake of Cd (23.0 μg), Hg (63.0 μg) and As (13.6 μg) through cereals was below the risk level except for Pb (634.0 μg) and Cr (263.1 μg). The dietary intake of Na (1860.0 mg), Mg (347.0 mg) and Mn (4600.0 μg) exceeded the toxic level while K (829 mg) was below the RDA. Conclusion: As the main meal of average Bangladeshi people is boiled rice served with some vegetables, our findings indicate that the residents of Dhaka city are at risk from Pb and Cr contamination and their dietary need for some important minerals and trace elements is not fulfilled by cereals.

This chapter focuses on the clergy of the Church of England. It first explains the process of selection and training for deacons and priests, along with their ordination, functions, and duties. It then considers the status and responsibilities of incumbents, patronage, and presentation of a cleric to a benefice, and suspension of presentation. It also examines the institution, collation, and induction of a presentee as well as unbeneficed clergy such as assistant curates and priests-in-charge of parishes, the authority of priests to officiate under the Extra-Parochial Ministry Measure, the right of priests to hold office under Common Tenure, and the role of visitations in maintaining the discipline of the Church. The chapter concludes with a discussion of clergy retirement and removal, employment status of clergy, vacation of benefices, group and team ministries, and other church appointments including rural or area deans, archdeacons, diocesan bishops, suffragan bishops, and archbishops.

Food is a major source of minerals for humans. The main objective of this study was to determine the intake level of 10 essential macro- (Na, K, Ca, and Mg) and trace elements (Cu, Zn, Mn, Fe, Cr, and Se) with major food groups among young adults. Dietary intake of elements was evaluated using the 24-h dietary recall technique in combination with F-AAS and ICP-OES methods. A very high intake of sodium and a very low intake of calcium, combined with inappropriate sodium/potassium ratio, may be harmful to the health of the population. Dietary intake of trace elements was within the range of reference values in the subjects, with cereals being the major source of a majority of those elements, while meat (38% for Na), vegetables (25% for K), and milk products (75% for Ca) were the main contributors to the daily dietary intake of macroelements. PCA revealed several visible trends in the datasetAmong men, the intake of Zn, Cr Na and K was significantly correlated with the consumption of meat and vegetables, whereas Mg, Se, Fe and Cu with cereals and water and beverages. Among women, the intake of Mg was significantly correlated with the consumption of meat and vegetables.

Breast-fed infants in Bangladeshi villages were weighed at 1, 2, 6, 9 and 12 months. The concentrations of zinc and copper in the breast milk were measured and the daily intake of these elements calculated. Breast milk Zn concentration decreased over the year but was comparable with that found in developed countries. The calculated daily intake decreased from 17·7 to 8·0 μmol (10–30% of recommended dietary allowances (RDA); National Academy of Sciences, 1980). Breast milk Cu concentration also fell over the year and was lower than that reported from developed countries. Calculated daily Cu intake was 1·95–2·63 μmol (RDA 7·81–15·63 μmol). Deficiencies of trace elements may therefore be a problem in poorly nourished communities where breast feeding is continued for several years with only small amounts of additional food. Breast milk may not be adequate as the only source of infant nutrition after the first few months of life in Bangladesh.

PIXE technique was applied to measurement of trace elements in total diet samples collected in Japan for estimation of their daily dietary intake. Results of PIXE analysis were compared with INAA Concentration of Cl, K, Mn and Zn by PIXE analysis well agreed with the results from NAA, while Ca, Fe and Cu showed different results between these two techniques. Preliminary data of elemental concentrations in Mate-cha, a kind of tea popular in South America, determined by ICP-AES indicated a little higher concentration of Cu than that by PIXE and much lower value than that by INAA For Zn. concentrations by PIXE and ICP well agreed to each other, while INAA gave much lower value. Japanese internal radiation doses by 137 Cs and 90 Sr were estimated to be 2.30µSv/year and 1.27µSv/year respectively as the effective dose equivalents using the daily intake data obtained for K and Ca.

Abstract NERO is a series of teleoperated wall climbing vehicles. Each vehicle carries a specific tool for assisting inspection of a nuclear reactor pressure vessel in the U.K. They adopted a simple sliding frame walking mechanism to cope with 250mm head room and 25mm obstacles on the surface. Vacuum suckers are used by the vehicle for climbing vertical surface. The NERO vehicle is driven remotely by an operator via a control console. The status of the vehicle and the control console is displayed on the console’s computer monitor. These vehicles completed their tasks successfully by September 1992.

The Status

The Association of Southeast Asian Nations (ASEAN) has, on various occasions, concluded treaties on behalf of its Member States. This raises some interesting questions: is ASEAN entitled to enter into treaties on behalf of its Member States; and if so, what should be the status of ASEAN and its Member States vis-à-vis the other party to the treaty? The issue is not one of whether the ASEAN Member States have consented to such a practice—it must be assumed that they have. Instead, the real issue is whether such treaty-making practice can and should be valid under international law, even if the Member States have consented for ASEAN to conclude these treaties on their behalf. This paper will argue that, under international law, ASEAN is entitled to conclude treaties on behalf of its Member States.
