The effects of future climatic changes on international water resources: the Colorado River,the United States,and Mexico

International water resources have been a source of contention in many parts of the world over the last few decades and such conflicts may grow in frequency and severity as future climatic changes alter the quantity or quality of limited water resources. Indeed, some future climatic changes appear inevitable due to growing atmospheric concentrations of carbon dioxide and other trace gases. Unless mechanisms for incorporating climatic changes into water agreements can be worked out, these changes may provoke further frictions and conflicts. One region with a history of political conflict over shared water resources is the Colorado River Basin in the United States and Mexico. While past disagreements over water have mostly been resolved, future climatic changes that adversely affect the existing hydrologic regime of the basin cannot be discounted. This paper examines the possibility that future long-term climatic changes may exacerbate shortages in the Colorado River. Political conflicts and tensions that arise from reductions in water supply in both the United States and Mexico are evaluated and discussed, together with recommendations for incorporating the issue of climatic change into existing international treaties and agreements.     

Further evaluation of immunocytochemical staining in the diagnosis of early myocardial ischaemic/hypoxic damage

The pattern of immunocytochemical staining with antibodies to caeruloplasmin, myosin, myoglobin and C-reactive protein seen in myocardium taken from deaths with macroscopic evidence of myocardial infarction and/or significant coronary artery atherosclerosis and from deaths with neither of these lesions has been correlated with H&E, PTAH and HBFP staining of myocardium and circumstances of each death indicative of antemortem hypoxia and/or ischaemia. Loss of staining with these antibodies correlated well with fuchsinorrhagia and both techniques are more sensitive than H&E and PTAH staining in the detection of early ischaemic/hypoxic damage to myocardium. However, their sensitivity is such that they appear to detect agonal changes and, therefore, cannot be used for specific diagnosis of early myocardial infarction.     

Comparative study of the sensitivity and specificity of the zinc and acid phosphatase spot tests for the detection of seminal stains

The sensitivity and specificity of a zinc spot test for the detection of semen were compared with those of an acid phosphatase detection method. As screening techniques both tests were found to be very sensitive, but the zinc test was more specific and was more reliable in older and especially in deteriorated specimens. It is concluded that the zinc spot test deserves at least the same place as the acid phosphatase test in the primary investigation of suspected semen stains and might well be the test of choice in older and poorly preserved stains.     

The shielding capacity of the standard military flak jacket against ballistic injury to the kidney

An animal model was designed to evaluate the ability of the standard military flak jacket to protect the kidneys from direct ballistic trauma. Yorkshire swine were anesthetized and their flanks were protected by flak jackets. Ballistic insults ranging from a low-velocity handgun to a high-velocity rifle were evaluated. The results demonstrate that a flak jacket provides adequate protection against low- and mid-velocity projectiles since none of the animals from this group had evidence of internal trauma and because only minor superficial surgical attention would have been required. Survivability in each case was considered to be excellent. The flak jacket failed to provide any protection against several types of high-velocity bullets. These weapons caused severe internal injury to the genitourinary system as well as to other major organ systems. Survival would have been unlikely.
