G93-1145 Management of the Army Cutworm and Pale Western Cutworm

This NebGuide describes the life cycle of the army cutworm and pale western cutworm, and provides recommendations for management.The army cutworm, Euxoa auxiliaris, and the pale western cutworm, Agrotis orthogonia, are sporadic pests that are distributed throughout the Great Plains. The army cutworm can be found throughout Nebraska, but is more common in the western half of the state. Because of the drier environment, the pale western cutworm is found only in the western third of Nebraska. Both cutworms can feed on a vast array of crops and weeds. Their major economic impact is limited to winter wheat and alfalfa, because these are the vulnerable crops growing in the early spring when larval feeding activity occurs. However, they can also cause substantial damage to early spring row crops (sugarbeets and corn), especially in areas where winter cereal cover crops are used.

Experimental Study on Friction between Saline Ice and Steel

Understanding the interaction of sea ice with offshore structures is of primary importance for the development of technology in cold climate regions. The rheological properties of sea ice (strength, creep, viscosity) as well as the roughness of the contact surface are the main factors influencing the type of interaction with a structure. A device was developed and designed and small scale laboratory experiments were carried out to study sea ice frictional interaction with steel material by means of a uniaxial compression rig. Sea-ice was artificially grown between a stainless steel piston (of circular cross section) and a hollow cylinder of the same material, coaxial to the former and of the same surface roughness. Three different values for the roughness were tested: 1.2, 10 and 30 μm Ry (maximum asperities height), chosen as representative values for typical surface conditions, from smooth to normally corroded steel. Creep tests (0.2, 0.3, 0.4 and 0.6 kN) were conducted at T = -10 ºC. By pushing the piston head towards the cylinder base, three different types of relative movement were observed: 1) the piston slid through the ice, 2) the piston slid through the ice and the ice slid on the surface of the outer cylinder, 3) the ice slid only on the cylinder surface. A cyclic stick-slip motion of the piston was detected with a representative frequency of 0.1 Hz. The ratio of the mean rate of axial displacement to the frequency of the stick-slip oscillations was found to be comparable to the roughness length (Sm). The roughness is the most influential parameter affecting the amplitude of the oscillations, while the load has a relevant influence on the their frequency. Guidelines for further investigations were recommended. Marco Nanetti - seloselo@virgilio.it

Oral mucosal findings related to tobacco use and alcohol consumption: a study on Swiss army recruits involving self-reported and clinical data

PURPOSE: The aim of the present study was to assess the oral mucosal health status of young male adults (aged 18 to 24 years) in Switzerland and to correlate their clinical findings with self-reported risk factors such as tobacco use and alcohol consumption. MATERIALS AND METHODS: Data on the oral health status of 615 Swiss Army recruits were collected using a standardised self-reported questionnaire, followed by an intraoral examination. Positive clinical findings were classified as (1) common conditions and anatomical variants, (2) reactive lesions, (3) benign tumour lesions and (4) premalignant lesions. The main locations of the oral mucosal findings were recorded on a topographical classification chart. Using correlational statistics, the findings were further associated with the known risk factors such as tobacco use and alcohol consumption. RESULTS: A total of 468 findings were diagnosed in 327 (53.17%) of the 615 subjects. In total, 445 findings (95.09%) were classified as common conditions, anatomical variants and reactive soft-tissue lesions. In the group of reactive soft-tissue lesions, there was a significantly higher percentage of smokers (P < 0.001) and subjects with a combination of smoking and alcohol consumption (P < 0.001). Eight lesions were clinically diagnosed as oral leukoplakias associated with smokeless tobacco. The prevalence of precursor lesions in the population examined was over 1%. CONCLUSIONS: Among young male adults in Switzerland, a significant number of oral mucosal lesions can be identified, which strongly correlate with tobacco use. To improve primary and secondary prevention, young adults should therefore be informed more extensively about the negative effects of tobacco use on oral health.

Landscapes of Poverty and Environment in Lao PDR

A key challenge for land change science is linking land cover information to human-environment interactions over larger spatial areas. Crucial information on land use types and people involved is still lacking. In Lao PDR, a country facing rapid and multilevel land change processes, this lack of information hinders evidence-based policy- and decision-making. We present a new approach for the description of landscape mosaics on national level and relate it to village level Population Census information. Results showed that swidden agricultural landscapes, involving 17% of the population, dominate 28% of the country, while permanent agricultural landscapes involve 74% of the population in 29% of the country.
