A North American Record for \u3ci\u3eValgus Hemipterus\u3c/i\u3e (Coleoptera: Scarabaeidae) and Information on its Life Cycle

A rotting American elm log containing adults of Valgus hemipterus (L.) was discovered on 6 May 1980, at the Rose Lake Wildlife Experiment Station, Shiawassee County, Michigan. This appears to be the first record of this European species in North America. Larvae were collected in the summer, and pupae and teneral adults in the early fall suggesting a univoltine life cycle with the adults overwintering

Gangguan Peredaran Darah Otak di Indonesia (Faktor-faktor Risiko dan Prevalensi pada Usia Lanjut)

Cerebrovascular accidents are mayor causes of death and disability in developed countries and are also increasing in developing countries like Indonesia. It is strongly related to hypertension, diabetes and ischemic heart disease which are prevalent in older age groups. A study of 2092 cases of cerebrovascular accidents in Indonesia in 1980 revealed that the most frequent risk factors were hypertension (68.5%), diabetes (20%), obesity (15%), hypercholesterolemia (13%), and hyperuricemia (7%). It was also found that 43% of the patients have heart disease like left ventricular hypertrophy, coronary heart disease, and valvular disease. Epidemiological studies on cerebrovaskular accidents have not been done in Indonesia, but hospital data show an increasing frequency of ate disease. Cipto Mangunkusumo Hospital admitted 320 patients in 1980, while 496 patients were admitted in 1984. Only one third of the cerebrovascular accident cases admitted to Cipto Mangunkusumo hospital were of the hemorrhagic type. The results of treatment of cerebrovascular accidents are still unsatisfactory. Mortality is high and those who survive become invalids. Prevention of risk factors, especially early treatment of hypertension can reduce the incidence of cerebrovascular accidents

Preliminary Test of Prescribed Burning for Control of Maple Leaf Cutter (Lepidoptera: Incurvariidae)

Leaf litter burning in the spring resulted in 87.5% mortality of maple leaf cutter pupae, Paraclemensia acerifoliella (Fitch). No apparent damage was observed on sugar maple or beech trees within the burn area

The Wool ComfortMeter and the Wool HandleMeter, new opportunities for wool

Two instruments have been developed by the Sheep CRC that provide the tools for a new standard in comfort and handle for the next generation of next-to-skin wool knitwear. The Wool ComfortMeter and Wool HandleMeter provide a rapid, accurate and objective measure of two important characteristics of wool knitwear that are currently determined by subjective assessment. The Wool HandleMeter allows the prediction of a set of handle attribute values that can quantify the hand feel of a lightweight jersey fabric. The instrument uses the principle of pushing a fabric sample through a ring. The force displacement curve associated with the fabric test is characterised and used to define each fabric. These values were then compared to the average handle values, as determined by a group of experts, of a large set of lightweight knitted fabrics. Algorithms were developed that enable the instrument to more accurately predict each of seven handle attributes than an individual expert. The Wool ComfortMeter provides a measure of the fibres that are protruding from the surface of the fabric that are responsible for the itchy sensation caused by some knitwear. The results from the instrument have been compared to the results from extensive wearer trials to provide an understanding of the relationship between the instrument value and the comfort perceptions of wearers. The results have shown a very clear relationship between the instrument and wearer trials

Hysteretic behavior of bladder afferent neurons in response to changes in bladder pressure

Abstract Background Mechanosensitive afferents innervating the bladder increase their firing rate as the bladder fills and pressure rises. However, the relationship between afferent firing rates and intravesical pressure is not a simple linear one. Firing rate responses to pressure can differ depending on prior activity, demonstrating hysteresis in the system. Though this hysteresis has been commented on in published literature, it has not been quantified. Results Sixty-six bladder afferents recorded from sacral dorsal root ganglia in five alpha-chloralose anesthetized felines were identified based on their characteristic responses to pressure (correlation coefficient ≥ 0.2) during saline infusion (2 ml/min). For saline infusion trials, we calculated a maximum hysteresis ratio between the firing rate difference at each pressure and the overall firing rate range (or Hmax) of 0.86 ± 0.09 (mean ± standard deviation) and mean hysteresis ratio (or Hmean) of 0.52 ± 0.13 (n = 46 afferents). For isovolumetric trials in two experiments (n = 33 afferents) Hmax was 0.72 ± 0.14 and Hmean was 0.40 ± 0.14. Conclusions A comprehensive state model that integrates these hysteresis parameters to determine the bladder state may improve upon existing neuroprostheses for bladder control.http://deepblue.lib.umich.edu/bitstream/2027.42/134628/1/12868_2016_Article_292.pd
