Tactical Satellite Communications in the 1990\u27s

The rapid advancements in electronic technology over the past few years indicate both the need for vastly improved communications capability and the means to provide that capability. Use of the EHF frequency bands allocated for satellite communications and the development of signal processing capability for communications satellites will allow the next generation of military communications satellites to overcome the capacity and interference resistance limitations of todays systems. These improvements will also allow the use of small, highly mobile earth terminals, a capability that is highly significant to the combat forces

Early manifestations of dementing illness: Treatment with glycosaminoglycan polysulfate

In a multicenter, placebo-controlled, double-blind clinical trial in 156 elderly patients with psychopathologic symptoms, glycosaminoglycan polysulfate was found to be a therapeutically effective agent in the treatment of the earliest manifestations of a dementing process. 2. Treatment with glycosaminoglycan polysulfate in the daily dosage of 600 LRU, administered on the basis of a divided dosage schedule for 24 weeks, was significantly superior to an inactive placebo on several outcome measures including the SCAG Total and factor scores (i.e., Cognitive Dysfunction, Withdrawal, Agitation/Irritability and Depression), the NOWLIS Total and Fatiguability factor scores, the MMSE, the HAM-D Total and Vegetative Symptoms factor score and the CGI Severity of Illness and Global Improvement. 3. The drug was well tolerated; vital signs and laboratory measures did not show clinically significant changes within the experimental period

Scoring tail damage in pigs: an evaluation based on recordings at Swedish slaughterhouses

<p>Abstract</p> <p>Background</p> <p>There is increasing interest in recording tail damage in pigs at slaughter to identify problem farms for advisory purposes, but also for benchmarking within and between countries as part of systematic monitoring of animal welfare. However, it is difficult to draw conclusions when comparing prevalence’s between studies and countries partly due to differences in management (e.g. differences in tail docking and enrichment routines) and partly due to differences in the definition of tail damage.</p> <p>Methods</p> <p>Tail damage and tail length was recorded for 15,068 pigs slaughtered during three and four consecutive days at two slaughterhouses in Sweden. Tail damage was visually scored according to a 6-point scale and tail length was both visually scored according to a 5-point scale and recorded as tail length in centimetres for pigs with injured or shortened tails.</p> <p>Results</p> <p>The total prevalence of injury or shortening of the tail was 7.0% and 7.2% in slaughterhouse A and B, respectively. When only considering pigs with half or less of the tail left, these percentages were 1.5% and 1.9%, which is in line with the prevalence estimated from the routine recordings at slaughter in Sweden. A higher percentage of males had injured and/or shortened tails, and males had more severely bitten tails than females.</p> <p>Conclusions</p> <p>While the current method to record tail damage in Sweden was found to be reliable as a method to identify problem farms, it clearly underestimates the actual prevalence of tail damage. For monitoring and benchmarking purposes, both in Sweden and internationally, we propose that a three graded scale including both old and new tail damage would be more appropriate. The scale consists of one class for no tail damage, one for mild tail damage (injured or shortened tail with more than half of the tail remaining) and one for severe tail damage (half or less of the tail remaining).</p
