Protecting Juvenile Flounder from Becoming a Crab Pot By-Catch

This study was devised to research a possible solution to reduce the bycatch of juvenile flounder when using the conventional crab pot. An escape panel for the juvenile flounder was constructed and installed into 10 crab pots, known as treated pots. To ascertain the validity of the project, 10 untreated pots were fished alternating with the 10 treated pots. On three rotations, of exactly the same number of days being fished, data was collected to determine if the panels were working as an escape for the juvenile flounder and if the panels had a impact on the number of crabs caught

Eliminating the by catch in the conventional crab pot

This study was devised to research a possible solution to reduce the bycatch of fishes when using the conventional crab pots. A perp panel was constructed and installed into 30 crab pots, known as treated (T). An additional 30 pots without perp panels were also used in the study as a control, known as untreated (UT). These pots were placed randomly in the Nansemond River and in the James River and the study was conducted 3 times. The data included the area being fished, the depth of the water, the water temperature, type of bottom, type of bait used, the number of crabs caught (male and female), and the type of by-catch including species and length

Phase II Protecting Juvenile Flounder from Becoming a Crab Pot By-Catch

This study is an attempt to discover new methods to reduce the by-catch of juvenile flounder when using conventional crab pots. An escape panel for the juvenile flounder was constructed and inserted into 20 crab pots, known as treated pots. To ascertain the validity of the project, 20 untreated pots were fished alternating with the 20 treated pots. On three rotations of exactly the same number of days being fished, data was collected to determine if the panels were effective as an escape for the juvenile flounder and if the panels had an impact on the number of crabs caught

Clinical assessment of the MOD-MEM cancer test in controls with non-malignant diseases.

A control series of 105 patients in hospital with non-malignant diseases was used in a limited clinical assessment of the MOD-MEM test. Twenty-seven positive results could be explained on the basis of destruction of nervous parenchyma, tissue necrosis, tuberculosis, malignant disease, etc. The remaining 13 unexplained positives showed a sex and age distribution in agreement with that predicted from cancer registration statistics if the MOD-MEM test detects cancer about 16 years before the clinical appearance of the disease

An Analysis of Conjunctive Goal Planning

This thesis develops a formal theory of planning, using a simple paradigm of planning that has been previously explored in work such as GPS, HACKER, STRIPS and NOAH. This thesis analyzes the goal interactions that occur when the goal is stated as a conjunction of subgoals. In this analysis we assume that the problem has a finite state space, and that operators are reversible. Graph theory can be used to characterize these subgoal interactions. The entire state space is treated as a graph, and each subgoal or conjunction of subgoals defines a subgraph. Each subgraph is composed of one or more connected components. Solving each subgoal by choosing a connected component that contains a final goal state is a necessary and sufficient condition for solving any planning problem. In the worst case, analyzing goal interactions is shown to be no more effective than enumerating the state space and searching. This complexity proves that no complete algorithm can solve all planning problems in linear time. The technique of goal ordering is analyzed, along with several extensions to that technique. While a generalization of goal ordering is possible, in the worst case generating the goal order requires as much computation as solving the problem by a brute-force search. A technique called capability analysis, derived from the connect component results, uses first-order logic to find the constraints that must apply as subgoals are achieved. A partial implementation uses counterfactual logic to identify the components of a world state that prevent the remaining subgoals from being achieved
