Evaluating Alberta’s Fall Index Netting Protocol for Assessing Northern Pike (Esox lucius) Populations
To assess the validity of Fall Index Netting (FIN) for monitoring Northern Pike (Esox lucius) populations, we tested five hypotheses relating FIN catches to independently measured abundance and sizes of Northern Pike, including testing the economic effectiveness of FIN monitoring. These tests used …

Using Pheromone Lures, Insecticide Netting, and a Novel Food-Grade Repellent to Develop BMSB IPM Strategies
… lure was placed on insecticide-incorporated mesh netting to be used in an attract-and-kill strategy to protect bell peppers. The pheromone and netting deployed within a pepper field resulted in more BMSB feeding on plants within 6.1 m to the attract-and-kill screen than in further peppers or …

Wire Netting Reduces African Elephant (<i>LOXODONTA AFRICANA</i>) Impact to Selected Large Trees in South Africa
… the effectiveness of wrapping protective wire netting around the trunk of the tree in preventing and reducing bark stripping by elephants. 2,668 trees, 1352 marula (Sclerocarya birrea), 857 knobthorn (Acacia Nigrescens), and 459 false marula (Lannea schweinfurti), were assessed for elephant …

Acoustic and Netting Surveys of Western Ozark Highlands Bats with Habitat Suitability Models for Three Threatened and Endangered Species
Bats in the United States and Canada are experiencing major population declines because of white-nose syndrome (WNS), a fungal disease that kills bats hibernating in caves. First discovered in New York in 2006, WNS has rapidly spread south and west across the United States. Camp Gruber Training …

The effect of removing tariffs and domestic taxes on insecticide treated nets (ITNs), netting materials and insecticides in Zimbabwe
The use of Insecticide Treated Nets (ITNs) has already proved to be a cost effective way of malaria vector control. The important emphasis now should therefore be on how to increase the accessibility and utilization of the mosquito nets through devising viable financing and promotional mechanisms …

Performance Quantification of Interlayer Systems in Flexible Pavements Using Finite Element Analysis, Instrument Response, and Non Destructive Testing
… of two interlayer systems (steel reinforcing netting and a newly-designed geocomposite membrane) in different pavement applications. Steel reinforcing netting and geocomposite membrane have been installed at the Virginia Smart Road in four different sections. Ground penetrating radar (GPR) …

Modeling reflective cracking development in hot-mix asphalt overlays and quantification of control techniques
… distinct interlayer systems, sand mix and steel netting with slurry seal, were examined for their effectiveness in controlling reflective cracking. The sand mix was modeled with the LVE model and bilinear CZM. The steel netting interlayer system was modeled with beam elements for steel wires and …

Non-Chemical Insecticidal Textiles
… a 100% polypropylene 200 holes per inch mosquito netting, a 100% cotton terry cloth, and a knit fabric of unknown fiber content with an unusual texture on one side similar to a shag carpet. Mortality in mosquitoes of 86.1% was seen 24 hours after the initial exposure of 15 minutes to the mosquito …

The management of foreign exchange risk by listed companies: an empirical study
… in combination with financial derivatives. Netting is the predominately used internal hedging technique by the survey respondents. There is a significant relationship between a firm's usage of netting as an internal hedging technique and the percentage of foreign currency denominated …

Empirical evaluation of the effectiveness of South Africa's marine protected area network in representing fish communities
… trawling, boat-based line-fishing and seine netting was compared across the EEZ of South Africa, including sites in designated MPAs. Multivariate statistics were used to assess the extent to which MPAs represent the full range of fish communities in South African waters. Results show there is …

PCB Integrated Matrix Transformer for a High-Power Single Phase CLLC Resonant Converter with the Novel Application of Circular Orthogonal Parallel Airgaps
… A gain range of 0.72 – 1.35 is calculated, netting a transformer configuration with a leakage inductance ratio, L_n, (L_n=L_m/L_r) range of 3-5. Further converter loss calculations condense the L_n range to 4 and 5. A PCB-based matrix transformer structure with built-in controllable leakage …

Food Habits, Growth, and Production of Young-of-the-Year Walleyes, Stizostedion vitreum vitreum (Mitchell), in a South Dakota Pond
… yielded 221.4 fish per hour, and trap netting yielded 2.1 fish per hour. Electrofishing had the highest yield per effort of all methods used, yielding 75.2 walleyes per man-hour. Seining yielded 45.0 walleyes per man-hour and trap netting yielded 10.1 fish per man-hour.</p>

Bioenergetics and growth of white steenbras, Lithognathus lithognathus, under culture conditions
… for mariculture. Fish were captured by seine netting, from nearby estuaries and transported to the laboratory where they were successfully kept for the duration of the experimental period. The fish were initially fed on white mussels and then weaned onto a diet of commercial trout pellets. The …

Evaluation of two reef materials and point or cove locations for construction of artificial reefs in Smith Mountain Lake, Virginia
… fishing surveys, SCUBA surveys, and trapping and netting surveys revealed several trends: 1. That sunfishes preferred tree reefs to tire reefs during the spring sampling period, and 2. that reefs effectively concentrated fishes as compared to control areas during the sampling period.

Ecology of Lake Ontario Brown Trout
… In conjunction with telemetry, vertical gill netting was used to evaluate brown trout location, depth and temperature distributions, and food preference during the summers of 1981 and 1982.

Shark nets in KwaZulu-Natal : an evaluation of catches and alternatives
… release rate. A published contention that shark netting has resulted in a proliferation of small sharks through reduced predation is re-examined and considered to be exaggerated. Reduced predation on dolphins, as a result of shark netting, is estimated. Considerably less fishing effort is applied …
