The aim of this thesis was to develop and validate squash-specific fitness tests to identify physiological determinants of repeat-sprint ability and performance in sub-elite and elite-standard squash players. Study one examined the validity of a squash-specific test of endurance capability and VO[2max]. Trained squash players and runners completed squash-specific and treadmill incremental tests to exhaustion. Squash players achieved greater VO[2max] on the squash-specific than the treadmill test while runners did not differ. Squash players exercised longer than runners on the squash-specific test despite similar VO2max. The squash test discriminated endurance capability between squash and non-squash players of similar fitness and elicited higher VO[2max] in squash players. The results suggest that it is a valid test of aerobic fitness in squash players. Study two assessed the reproducibility of physiological and performance measures from the squash specific test in county-standard players. Test-retest variability was low for all measures (Typical error < 5%) though the magnitude varied depending on the metric used. Studies three and four examined the validity and reproducibility of squash-specific tests of change-of-direction speed and multiple-sprint ability. County-standard squash players and footballers completed squash-specific and equivalent non-specific tests on separate days. Performance time was recorded. Participants repeated the tests seven days later to assess reproducibility. Squash outperformed non-squash players on the squash-specific tests despite similar non-specific capabilities. Squash-specific tests discriminated squash player rank while non-specific tests did not. Test-retest variability was low (Typical Error < 3%) for both tests. Squash-specific tests predicted ability in squash players and discriminated between squash and non-squash players of equal nonspecific fitness. The findings suggest that the squash-specific tests are valid for the assessment of high-intensity exercise capabilities in squash players. Studies five and six explored correlates of multiple-sprint ability and performance in sub-elite and elite squash players. Squash-specific and general tests were performed by regional league players ranging from division three to premier standard and elite players on three tiers of a national performance program. In sub-elites, multiple-sprint ability and endurance capability discriminated performance and multiple-sprint ability was related to change-of-direction-speed, VO[2max] and endurance capability. In world-ranked men and women, the ability to perform and sustain rapid changes of direction correlated with multiple-sprint ability and together with multiple-sprint ability discriminated performance. Aerobic fitness was not related to performance or multiple-sprint ability in elite players. Senior elites performed better than players on the talented athlete scholarship scheme (TASS) on all tests except VO[2max] and counter-movement jump. Drop-jump power and reactive strength discriminated senior and transition level from TASS players and indices from the multiple-sprint test discriminated seniors from transition and TASS players. This thesis has validated squash-specific tests of endurance and high-intensity exercise capabilities. These tests have shown that high-intensity exercise capabilities determine performance in elites while sub-elite performance is determined by multiple-sprint ability and endurance capability. The findings can be used to improve assessment of training effects and to inform the design of effective training methods.

Although most vegetables are grown using conventional tillage (CT) practices, no-tillage (NT) is becoming more prominent in vegetable production due to growers gaining more understanding of the economic and ecological benefits associated with the NT production system. Nitrogen (N) fertility management in NT systems is important to maximize yield productivity, but there is little available information on N fertilizer recommendations for vegetable crops grown in this production system. Therefore, two field studies were conducted at a grower location in southern Illinois to determine the effect of N application rates in NT zucchini squash and cucumber production following the herbicide burn-down of a wheat cover crop in early spring. Results indicated that the maximum total squash fruit yield was achieved when 30 to 120 lb N/acre was sidedress applied [or a range of 125 to 210 lb total N (pre-plant, soil, and applied N)/acre]. Although squash plant growth was maximized when 180 lb N/acre was sidedressed (or a range of 264 to 273 lb total N/acre), the overall yield was less compared to the 30 to 120 lb N/acre rates. Cucumber results indicated that maximum total fruit yield was achieved again at 30 to 120 lb N/acre sidedress rates (or a total N rate range of 114 to 208 lb/acre). Cucumber plant growth was maximized at a sidedress application of 120 to 180 lb N/acre, although yield decreased at the 180 lb N/acre sidedress rate (or 260 to 270 lb total N/acre). It appears that if cucurbit vegetables have high amounts of N available in the soil through over application of N fertilizer, the excess N will be used for plant vegetative growth rather than for fruit production. These studies indicated that when too much N is applied in both NT cucumbers and zucchini squash, these high N rates will stimulate vegetative growth (as indicated by high plant vigor and leaf chlorophyll content) while reducing fruit yields.

Em programas de melhoramento, a defasagem de uns poucos dias pode provocar perdas significativas de alguns cruzamentos. Objetivou-se estudar formas de conservação de flores masculinas de aboboreira ‘Piramoita’ para posterior cruzamento e produção de sementes, pois a conservação de grãos de pólen é inviável para cucurbitáceas. O experimento foi conduzido em Campo Grande (MS), de agosto a dezembro de 2001. A partir do início do florescimento de 40% das plantas (novembro), aplicou-se os tratamentos (tempo de armazenamento e substânciasdiluições). Colheu-se flores masculinas recém-abertas, padronizou-se o comprimento dos pedúnculos (±10cm) e mergulhou-os (± 3cm basais) em béqueres contendo as substâncias-diluições (água, sulfato de alumínio 25mgL-1 e 50mgL-1, sacarose 25gL-1, 50gL-1 e 75gL-1). Utilizou-se duas testemunhas: flores recém-colhidas (sem nenhum tratamento) e polinização natural (por insetos), onde as flores ficaram disponíveis às visitas dos insetos nos mesmos dias em que foram realizadas as polinizações e todas as outras flores foram eliminadas. As flores foram armazenadas por um ou dois dias, em temperatura ambiente (±25ºC) ou em geladeira (±8ºC)... . / In the production of hybrid seed of summer squash, flowering may not coincide, even when programming the sowing of the parentals. In breeding programs the delay of a few days may result in significant losses of some crossings. It was aimed to study forms of storage of staminate flowers of summer squash cultivar Piramoita for subsequent crossing and seed production, because pollen storage in cucurbits is unviable. The experiment was carried out in Campo Grande (MS), from August to December, 2001. Treatments (time of storage and substance-dilutions) were applied when 40% of the plants initiated flowering (November). Recently-open staminate flowers were harvested, stalks were standardized lengthwise (± 10cm) and dipped (± 3cm basal) in beckers containing the substance-dilutions (water, aluminum sulfate 25mgL-1 and 50mgL-1, sucrose 25gL-1, 50gL-1 and 75gL-1). Two standards were used: recently-harvested flowers (without any treatment) and natural pollination (insects), where the flowers were available to the visit of the insects in the same days as the pollinations were accomplished and all other flowers were eliminated. Flowers were stored for one or two days, at room temperature (±25ºC) or in the refrigerator (±8ºC). The selected pistillate flowers were bagged in “pre-anthesis”, in the afternoon previous to the crossing and again after the pollination. In each plant, only one cross was made. In the natural pollination, also only one flower in each plant was left “available” to the insects... (Complete abstract, click electronic address below).

We evaluate SQUASH, a new MAC for RFID, in hardware and software. A smaller hardware design for SQUASH is proposed which also reduces latency. Area and latency in hardware are reduced further with a new variant we call permuted SQUASH. We explore SQUASH on embedded microprocessors and propose a method to choose the optimal partial product ordering to reduce latency.

Cucumber (Cucumis sativus L.), pumpkin (Cucurbita maxima Duch. ex Lam.), and summer squash (Cucurbita pepo L.) are economically important crops in Virginia. Only a few herbicides are registered for weed control in these crops. Halosulfuron is a sulfonylurea herbicide which controls several broadleaf weeds and yellow nutsedge (Cyperus esculentus L.). Cucurbit crops have some tolerance to this herbicide. The efficacy of halosulfuron for control of several weed species and tolerance of four vine crops to halosulfuron were investigated in field and greenhouse studies in 1999, 2000, and 2001. In the field, halosulfuron was applied to cucumber, pumpkin, zucchini squash, and yellow summer squash at 4, 9, 18, and 27 g ai/ha preemergence (PRE) and postemergence (POST) in combination with clomazone at 174 g ai/ha plus ethalfluralin applied PRE at 630 g/ha. Crop injury, weed control, and crop yield was collected from the field studies. Weed control by halosulfuron was dependent upon application method. Halosulfuron applied preemergence controlled only common ragweed (Ambrosia artemisiifolia L.) and smooth pigweed (Amaranthus hybridus L.). Postemergence halosulfuron controlled common ragweed, smooth pigweed, morningglory species (Ipomoea spp.), yellow nutsedge, and rice flatsedge (Cyperus iria L.). All four crops treated with halosulfuron produced yields equal to or higher than the crops receiving clomazone and ethalfluralin alone or the hand-weeded check. In the greenhouse, tolerance of cultivars of each crop to halosulfuron was investigated with the same rates applied in the field. Cultivars responded similar to postemergence halosulfuron applications with respect to fresh and dry weights in all four crops. The response of several populations of acetolactate synthase inhibiting (ALS) resistant smooth pigweed to postemergence halosulfuron was also investigated. Halosulfuron activity against ALS-inhibitor resistant smooth pigweed was population dependent. In the greenhouse, postemergence halosulfuron at the same rates used in the field studies controlled yellow nutsedge. / Master of Science
