Abstract From the Summit of South American–Arab Countries (ASPA) created in 2005, UAE–South American relations have continued to develop based on a combination of pragmatism, threat perception, political support and expanding economic interests. We argue that the strength of UAE engagement in this region is consistent with its attempts to build, deploy and benefit from soft power globally through economic statecraft in a mutually reinforcing series of bilateral and multilateral relationships. These include forums such as the Southern Common Market (MERCOSUR) and the expanding BRICS grouping (Brazil, Russia, India, China and South Africa). The article draws on primary and secondary data in English, Portuguese and Spanish, focusing mainly on UAE relations with Brazil and Venezuela. We find that through a myriad of growing investment relations and first‐mover advantage on arms and industrial cooperation, the UAE is well positioned vis‐à‐vis other Gulf Cooperation Council (GCC) states to benefit from the economic, diplomatic and security ties that could boost its relational autonomy in a competitive and uncertain regional and international environment.

Salinity alterations will likely change the plant and environmental characteristics in coastal marshes thereby influencing soil carbon accumulation rates. Coastal Louisiana marshes have been historically classified as fresh, intermediate, brackish, or saline based on resident plant community and position along a salinity gradient. Short-term total carbon accumulation rates were assessed by collecting 10-cm deep soil cores at 24 sites located in marshes spanning the salinity gradient. Bulk density, total carbon content, and the short-term accretion rates obtained with feldspar horizon markers were measured to determine total carbon accumulation rates. Despite some significant differences in soil properties among marsh types, the mean total carbon accumulation rates among marsh types were not significantly different (mean ± std. err. of 190 ± 27 g TC m−2 year−1). However, regression analysis indicated that mean annual surface salinity had a significant negative relationship with total carbon accumulation rates. Based on both analyses, the coastal Louisiana total marsh area (1,433,700 ha) accumulates about 2.7 to 3.3 Tg C year−1. Changing salinities due to increasing relative sea level or resulting from restoration activities may alter carbon accumulation rates in the short term and significantly influence the global carbon cycle.

NSPE/PEPP recommends continuation of Consulting Engineering: A Guide for the Engagement of Engineering Services, (Manual 45) as it has become a standard of the industry. A detailed review suggests the consistent use of the title project representative in lieu of inspector and, in general, suggests more coordination with the recommendations of the Engineer's Joint Contract Docr uments Committee. Recommendations are made for inclusion of information on the American Bar Association's model procurement code; use of the federal 254 and 255 forms; listing of additional special services; a discussion on the determination of “fee” in a cost‐plus‐a‐fixed‐fee contract; defining a “limitation‐of‐cost” type contract; and comments on the use of percentage cost of construction curves.

The purposes of this paper are two-fold. First, to establish the conditions under which piecemeal welfare policy is still useful. Second, to demonstate a method which can be used to remove the outstanding problem that arises in attempts to apply the General Theory of the Second Best. In both cases, policy-makers can turn to the real-world data on prices, quantities, and incomes.

Studies on the Carcinogenicity of Pentachloroethane in Rats and Mice. Mennear, J.H., Haseman, J.K., Sullivan, D.J., Bernal, E. and Hildebrandt, P.K. (1982). Fundam. Appl. Toxicol. 2:82–87. The carcinogenicity of chronically administered (41 to 103 weeks) technical-grade pentachloroethane (PCE) was assessed in groups of 50 male and female Fischer 344 rats and B6C3F1 mice. The major contaminant in the PCE sample used for the chronic study was hexachloroethane (4.2%). Prechronic studies (two and 13 weeks repeated dose) employing gavage doses of from 5.0 to 1000 mg/kg/day of PCE failed to reveal specific target organ toxicity in these species. In the absence of treatment-related pathological changes during the prechronic tests, the doses for the chronic studies were set on the basis of survival and body weight gains during the 13-week repeated dose study. During the chronic studies dose levels of 75 and 150 mg/kg for rats and 250 and 500 mg/kg for mice were administered, by gavage, five days per week. The survival of high-dose rats (both sexes) was significantly reduced as compared to the survival of control animals and that of the low-dose males was slightly, but not significantly, reduced. Although the administration of PCE to rats did not increase the incidence of primary tumors, it did produce a significant dose-related increase in the incidence of chronic renal inflammation among males. The survival times of all treated groups of mice were significantly shortened by PCE administration. Despite this reduced survival time, the incidence of hepato-cellular carcinoma was significantly increased in all treated groups. With the exception of a dose-related increase in the incidence of hepatocellular adenoma among females, there were no other significant increases in primary tumor incidence in mice. Neither renal lesions in rats nor hepatocellular carcinoma in mice were considered to be adequate explanations for the decreased survivals. Complete histopathological examinations failed to reveal the cause of decreased survival. The results of the study show that technical-grade PCE, like numerous other chlorinated ethanes, is an hepato-carcinogen for B6C3F1 mice. This interpretation for PCE per se, however, must be tempered because the major contaminant, hexachloroethane, has been shown to produce hepatocellular carcinoma in mice. While the results obtained in rats suggest a species difference in susceptibility, the reduced survival in this species may have contributed to the absence of a carcinogenic effect.

Ion-selective eletrodes have been used to monitor urea and inorganic phosphate removal during dialysis. The dialysate outlow concentrations from a single pass beside controller were used to compute instantaneous serum concentrations. The urea data are in agreement with a single pool reservoir model; the inorganic phosphate removal was not log-linear, indicating rate limiting intracompartmental transfer. The procedure can be applied to the computation of urea generation rates and thus provide information on the protein catabolism rates of the patient; in addition, the monitor provides continuous checks on the dialyzer performance.

Glucose, lactic-acid, and oxygen metabolism of BHK and L929 cells on artificial capillary perfusion units have been studied using several different modes of perfusion. After 7 to 10 days, cells planted in the extracapillary compartment of culture units containing 80 to 150 fibers reached populations that used 0.073 +/- 0.025 mumol per min glucose and 0.76 +/- 0.26 microliter per min oxygen and excreted 0.078 +/- 0.038 mumol per min lactic acid. From these data it is estimated that these units contain approximately 2 x 10(7) cells. The metabolic rate of cultures perfused through the capillaries or through the extracapillary compartment was not affected significantly by change in flow rate except at perfusion flow rates less than or equal to 0.05 ml per min. The cell population, as measured by metabolic activity, did not increase significantly when the serum content of the medium was less than or equal to 1%. No major differences were found in glucose utilization rates of equal numbers of cells on artificial capillaries, on short-term suspension culture, or as monolayers in plastic flasks. Artificial capillary perfusion may provide a simple system for studying metabolism of mammalian cells in culture.
