Abstract:
This study focuses on the floristic composition of aquatic and semi-aquatic plants in the SASKWater canal system and their potential effect on irrigation systems. A checklist, evaluation, and synthesis of the species identified in this survey before and after the application of the herbicide Magnacide are provided, in addition to a brief discussion of the environmental effects of Magnacide. Thirty-three species in 26 genera within 20 plant families were identified. Two unidentified green algae were also collected. Common aquatics (i.e., green algae, Potamogeton spp., Alisma gramineum, A. plantago-aquatica, Ceratophyllum demersum, and Myriophyllum sibiricum) combined with debris from terrestrial plants were the primary contributors to blockage of irrigation drains. In general, the concentration of Magnacide used in this study had a minor effect on aquatic plant diversity, but effectively reduced plant density. However, the long-term effects of pesticides on the surrounding aquatic and terrestrial environments of the SASKWater irrigation system are unknown.

Abstract:
Catfish (Clarias gariepinus) was cultured with an aquatic plant, water hyacinth/eceng gondok (Eichornia crassipes), kangkung air (Ipomea aquatica) or kapu-kapu (Pistia stratiotes) in concrete ponds, for 3 months. Catfish cultured without aquatic plant was used as a control. The experiment was carried out to evaluate the survival rate as well as the growth of fish and aquatic plants.The survival rates of catfish cultured with I. aquatica, E. crassipes, and P. stratiotes were 76, 87, and 98%, respectively. In addition the survival rate of catfish cultured without any aquatic plant was 93%. The weight gain of catfish was 14,1-16,2 kg per pond. Whereas, the total weight gains of aquatic plant were 37,0, 27,7 and 7,7 kg per pond for E. crassipes, P. stratiotes, and I. aquatica,. Respectively. Dissolved oxygen, and the concentrations of NH3, NH4+ and PO43- in water with aquatic plants were higher than that of in water without aquatic plant. However, the concentration of CO2 was higher in water with aquatic plant.

Abstract:
The present article focused on aquatic vascular plants diversity and their conservation status in natural and manmade wetlands habitats of Sadullapur Gaibandha. The study was conducted in between May 2019 to June 2020. A total of 52 aquatic plant species was recorded from Sadullapur Gaibandha in the present study. These are assigned to 35 genera under 30 families. For each species scientific name, local name, family, division, habit, habitat, use and status are provided. Ecological habitats analysis of aquatics shows variations. Among them, 37% species prefers to grow near the edge of water, 13% submerged, 11% as emergent, 11% as free floating and 28% as rooted floating in the aquatic habitat. In case of submerged species, they produce flowers on surface of the water. After pollination fruits remain under water up to maturation. Among them, 49% species used as fodder, 22% as medicinal, 4% as aquarium purpose, 9% as vegetable, 6% as edible, 10% as fish food in the study area. The population number of different aquatic plant species in habitats is not uniform. Overall analysis showed that 46% aquatic plant species in the study area found to be rare, 44% species found common and 10% species found as abundant. This status of aquatic plant species is very preliminary. Based on field observations and discussion with local people we are able to identify a good number of rare aquatic plants and also pointed some conservation measures for them in future. The investigation recorded a number of rare aquatic plant species from the study area. These are Trapa bispinosa (Singara), Nelumbo nucifera (Paddo), Nymphaea pubescens (Sada shapla), Oenanthe javanica (Panidhone), Nymphaea rubra (Lal shapla), Ottelia alismoides (Panikola), Enhydra fluctuans (Titidata) and Centrostachys aquatica (Thuash). Populations of such species in the wild are very rare because of local demand for the use. These species need to be cared for conservation.

Abstract:
The purpose was to examine attitudes of aquatic instructors (female, n = 59; male, n = 23) toward teaching swimming to students with mild to severe disabilities in an inclusive setting. Aquatic instructors from 28 states representing 75 cities across the U.S. participated in this study. Data were collected by mail with a modified version of Rizzo’s (1984) “Attitudes of Physical Educators Toward Teaching Handicapped Pupils” (renamed “Physical Educators’ Attitudes Toward Teaching Individuals with Disabilities - Swim”). A correlated t test showed that aquatic instructors were significantly more favorable toward teaching aquatics to students with mild disabilities than students with severe disabilities. Stepwise multiple regression analysis indicated that conducting an inclusive aquatic program was the best predictor of favorable attitudes toward including students with mild disabilities, while having more certifications in aquatics was the best predictor of favorable attitudes toward including students with severe disabilities in regular aquatic programs.

Abstract:
Ex-situ culture studies of five selected aquatic macrophytes, namely Nymphaea nouchali Burm. f., Enhydra fluctuans Lour., Ipomoea aquatica Forsk., Hygroryza aristata (Retz.) Nees ex Wight & Arn. and Limnocharis flava (L.) Buch. were carried out. Comparing the biochemical composition of the above mentioned five aquatic macrophytes, on an average, Enhydra fluctuans was found to contain highest amounts of proteins (18.20%) and Ipomoea aquatica contains highest amounts of carbohydrate (58.60%). Lowest amounts of proteins (14.35%) were recorded in Hygroryza aristata and Limnocharis flava. On the other hand lowest amounts of carbohydrates were obtained in Nymphaea nouchali. Ipomoea aquatica contained highest amounts of energy (321.23 kcal) and lowest amount was observed in Limnocharis flava. The five aquatic plants were low in fiber, fat and also in ash. Among all the five aquatic macrophytes, highest values of calcium and phosphorus were found to be present in Limnocharis flava and iron was highest in Nymphaea nouchali. Lowest values of calcium and phosphorus were present in Ipomoea aquatica and lowest amount of iron was present in Limnochris flava. The present study demonstrated that, these five aquatic macrophytes are the important sources of carbohydrate, protein and minerals, which are suitable for incorporation in human diet and feed also.

Abstract:
The professional in therapeutic recreation has the potential to interact with a variety of other persons who are involved in the life of an individual with a disability. If that individual participates in an aquatic program, one of the persons with whom a therapeutic recreation staff member interacts is the professional in aquatics. To make that interaction as productive as possible, this article will explore several aspects of the interaction between professionals in therapeutic recreation and professionals in aquatics. There are two aspects to the role of the aquatic professional and that professional’s interaction with therapeutic recreation staff participating in the collaboration process when working with individuals with disabilities. The aquatic professionals’ first job is to obtain information that can possibly impact the aquatic participation of the individual with a disability. If the aquatic program is part of a broader therapeutic recreation program, the primary source for that information may be the therapeutic recreation staff. Second and more often overlooked, there is information that the aquatic professional can provide to other individuals, professionals in therapeutic recreation, and caregivers alike, who also interact with the person with a disability. Because of the unique nature of staffing and participation in aquatics, participation in the collaborative process may be difficult. This article explores the specific details of the interactions of the aquatic professional in the collaboration process. Barriers to collaboration are discussed and possible solutions are presented.

Abstract:
Among professionals a need exists to compile benchmark data in all areas for the field of aquatics. To address this need, the questionnaire “Benchmarking Study for Campus Aquatic Programs” was created and distributed to NIRSA members. The questionnaire focuses on gathering data related to aquatic staff, facilities, and programs. Results indicate that the job responsibilities and certifications for hourly staff positions are similar across institutions. Pay rates for each hourly position are not unanimous for each position, but rather have a range that was common. Programming questions address available pool time and how it is divided among various activities. This article presents the collected data to establish benchmark statistics for the aquatics community with the intent that it be used as guidelines or benchmarks by aquatic professionals and decision makers in the development of recreational aquatics programs.

Abstract:
Plants play a pivotal role in human medicine, offering a vast array of bioactive compounds with therapeutic properties. As the main producers in most water habitats, aquatic plants are crucial. Though the aquatic habitat is rich in plant species, little research has been done on their medicinal potential. Some studies studied aquatic flora's ethno-medicinal, economic, and edible functions. Aquatic plants contain unique biological properties that could be used in agriculture, ornamentation, nutraceuticals, horticulture, and medicine. Aquatic plants, such as Eichhornia crassipes, Ipomoea aquatica, and Hydrilla verticillata, possess valuable effects like antimicrobial, antitumor, and antioxidant effects. Despite their potential, aquatic plants have often been undervalued, and more work required to fully explore their medicinal properties in various regions. In this review aquatic plants from India which is calmed to cure various diseases in Indian system of medicine. Moreover, the present review highlights the therapeutic potential of above three aquatic plants, urging researchers to evaluate their medicinal effectiveness and consider their applicability in medical fields.

O objetivo deste trabalho foi estudar a distribuição das macrófitas aquáticas em rios da planície costeira da bacia do rio Itanhaém. A abordagem adotada foi uma combinação de estudos observacionais e experimentais. No primeiro capítulo, estudou-se a distribuição das macrófitas aquáticas em relação a variáveis ambientais da água e do sedimento em 97 km de rios em duas estações do ano (verão e inverno). A salinidade foi a principal variável ambiental responsável pela separação das macróf5tas aquáticas em duas comunidades distintas, a do estuário e a dos rios. As principais espécies que ocorreram no estuário foram Spartina alterniflora. Crinum procerum e Scirpus califhrnicus, sendo que a primeira ocorreu em trechos de maior salinidade, a segunda em trechos com salinidade intermediária e a última em trechos de menor salinidade. As espécies de água doce mais freqüentes foram Egeria densa, Eichhornia azurea, Eichhornia crassipes. Pistia stratiotes, e Salvínia molesta. Egeria densa tendeu a ocorrer em trechos com maior transparência. menor nitrogênio total e maior fração areia no sedimento. Eichhornia azurea tendeu a ocorrer em locais com alta transparência e baixas concentrações de nitrogénio total. Finja siratiotes tendeu a ocorrer em trechos de rios com maiores concentrações de nitrogênio total na água. A freqüência de ocorrência das principais espécies não diferiu entre o verão e o inverno, provavelmente devido a ausência de uma estação seca. No segundo capítulo, se estudou a ocorrência das macrófitas aquáticas em função da vegetação ciliar e da morfologia de canal em três trcchos distintos de rios. No estuário do rio ltanhaém. a ocorrência de macrófitas aquáticas emergentes foi correlacionada com o sombreamento das árvores de mangue e a declividadc da área litorânea... .
The aim of this research was to study the distribution of aquatic macrophytes in coastal piam rivers of ltanhaém basin. lhe research approach was based on observational and experimental studies. In the first chapter, the distribution of aquatic macrophyte was correlated to water and sediment environmental variables in 97 km of rivers and in two periods (summer and winter). Salinity was the most important environmental variable to separate the aquatie rnacrophytes in two distinct communities: estuarine and freshwater communities. The main species found in the estuary were Spartina alterniflora, Crinum procerum and Scirpus califohiicus. lhe first species was found in water with higher salinity, the second in water with intermediate salinity and the Iatter in less saline water. lhe most frequent &eshwater species were Egeria densa, Eichhornia azurea, Eichhornia crassipes, Pistia strarioles and Sal Wnia molesta. Egeria densa tended to be present in river sections with high water transparence. low total nitrogen, and high sand fraction in sediment. Eichhornia azurea tended to occur in sections with high water transparence and low total nitrogen. Pistia stratiotes tendecl to occur in river sections with high total nitrogen. lhe &equency of occurrence aquatic macrophyrtes did not significantly differed hetween sunimer and winter. due probably to the absence of a dry season. In the second chapter, we investigated the influence of riparian vegetation and stream channel morphology on aquatie rnacrophyte distribution in three streams with dstinguished landscape. In the estuary of ltanhaëm River, the occurrence of emergent rnacrophytes was correlated with mangrove shading and slope of littoral region. In Preto River...

Abstract:
Projektet är en stad som ligger mellan Umeå och Vasa (Finland), det är den smalaste delen av Bottniska viken med bara ca 60 km öppet hav. Jag ville undersöka vad det fanns för möjligheter med en stad som utnyttjar sitt läge. Så jag planerade en offshore hamnstad som bygger sig själv och sprider sig. Varför? 60-talets men även samtida megastrukturer planerades ofta för att ge en teknisk lösning på ett visst problem. De här problemen vare sig det är bostadsbrist eller klimatförändring är fortfarande aktuella och lösningarna likaså. Därför ville jag använda min struktur som ett redskap för att testa och reflektera kring dessa idéer för boende. En jurymedlem jämförde mig kritiskt vid en skata som plockat silvret från mina referenser, men det han inte förstod var att jag plockade silvret just för att i min fiktiva värld analysera det. Analysen gjorde jag genom att hitta på invånare som med sinne och själ fick reflektera kring livet i en modul och etc.
The project is a city located between Umeå and Vasa, it is the most narrow part of the Gulf of Bothnia with only 60 km of open waters. I wanted to investigate existing possibilities with a city that exploits its location. So I designed an offshore port city that builds itself and grows. Why? The megastructures of the 60’s but also contemporary ones were often planned to give a technical solution to a certain problem. These problems whether it’s housing shortage or climate change are still current and the solutions as well. This is why I wanted to use my structure as a tool to test and reflect about these concepts of living. A member of the jury critically compared me to a magpie that had picked the silver of my references, but what he didn’t understand was that I had picked the silver to analyze it in my fictional world. I made the analysis by imagining inhabitants that through their mind and soul reflected on life in a module and etc.

Abstract:
The aquatic plant Ipomoea aquatica is a popular vegetable in Southeast Asia, often cultivated in nutrient rich and polluted waters. The overall aim of this thesis was to estimate potential risks for human health and reduced plant growth due to accumulation and toxicity of total-Hg, methyl-Hg, Cd and Pb. In plants from cultivations in Thailand, the concentrations of Cd and Pb in the shoots were well beneath recommended maximum values for human consumption, but at some sites the Hg concentrations were high. It was demonstrated that I. aquatica has the capacity to accumulate much higher Cd and Pb concentrations in the shoots than found in field-cultivations, before exhibiting toxic symptoms. The Hg concentrations, however, occasionally reached levels that are toxic for the plant. Up to11% of total-Hg was methyl-Hg, the most toxic Hg species, though at one site it was 50-100%. To study if methyl-Hg is formed in I. aquatica, plants were exposed to inorganic Hg through the roots. Of the Hg that reached the young, metabolically active parts of the shoots, a part was transformed to methyl-Hg. A major proportion of absorbed metals was retained in the roots, which had a high tolerance for high internal metal concentrations. The nutrient level did influence accumulation and effects of Hg, Cd and Pb in I. aquatica. Low external nutrient levels resulted in increased metal accumulation in the shoots and in metal-induced toxic effects in the plant at low external metal levels. A generous supply of sulphur or nitrogen induced formation of thiol-rich peptides in I. aquatica, compounds that have a metal detoxifying effect in plants. To conclude, the levels of Cd and Pb in field cultivated I. aquatica do not pose any apparent threat to human health or risk for reduced plant growth. The levels of Hg however, were high at some sites and could be a health threat, for children and foetuses in particular, and especially considering the presence of methyl-Hg. The use of fertilizers is favourable as it reduces the risk for increased metal concentrations in I. aquatica and for reduced crop yields.

Abstract:
Low back pain (LBP) is a widespread problem affecting a number of people. Traditionally treated by nonoperative approaches the recent development of water currents and treadmills imbedded into pools has spurred physical therapists and athletic trainers to incorporate the use of aquatic therapy into their rehabilitation programs. OBJECTIVE: Determine if select trunk muscle activity levels are different in water-based exercises compared to land-based exercises. METHODS: 11 healthy male participants age 25.9 ± 5.53 years, whom did not have a history of and were not currently experiencing LBP or injury. Muscle activity was monitored via electromyography (EMG) at the rectus abdominis (RA), external oblique (EO), lower abdominals (LA), erector spinae (ES), and lumbar multifidis (MT). Each subject performed (1) maximum voluntary contractions (MVC’s), (2) land-based exercises, and (3) water-based exercises. A paired samples t test was used to compare abdominal bracing (ABbrace), abdominal hallowing (ABhol), Anterior/Posterior pelvic tilts (APTilts), and lateral pelvic tilts (LatTilts) between comparable land and water conditions; general linear model-repeated measures was run to compare the 11 different water exercises; ABbrace, ABhol, APTilts, LatTilts, physioball push down (PBPushDown), PB lateral flexion, PB transverse rotations, stationary marching, leg abduction, and wall sits with sagittal and transverse plane arm movements. Follow-up multiple comparisons (LSD) were performed between water exercises using a Holm’s corrected alpha level set at 0.05. RESULTS: Land-based exercises elicited greater EMG activity compared to water-based activities for all muscles (%MVC land vs. %MVC water): RA %MVC (8.3-19.3 vs. 2.1-9.7, P = .003-.029); LA %MVC (27-105 vs. 5.2-25, P = .001-.016); EO %MVC (13-59 vs. 4.8-24.5, P = .001-.303); ES %MVC (19.1-37.6 vs. 7.75-22.1, P = .001-.039) and MT %MVC (16-25.4 vs. 5.9-8.8, P = .00-.005). For water comparison ABbrace and PB exercises produced the most muscle activity while WallSitSag/Trans consistently produced the least muscle activity. CONCLUSION: Even with reduced muscle activity in the water, the calculated % mean MVCs were high enough (at or below 25% MVC) to provide muscle endurance and stability gains. With the information provided from the analysis of water exercise comparison, practitioners can effectively progress patients through a rehabilitation program.

O objetivo deste trabalho foi avaliar o ganho de biomassa de Eichhornia crassipes cultivada em microcosmo em diferentes épocas do ano. O experimento teve duração de 189 dias e ocorreu entre abril e outubro de 2006. Indivíduos de E. crassipes foram cultivados em um sistema de recirculação de água composto por 3 unidades experimentais. O fluxo de água foi contínuo (vazão de 0,25 L min-1) e nutrientes foram adicionados semanalmente. Valores de nitrito, nitrato, ortofosfato, oxigênio dissolvido, condutividade elétrica, turbidez, pH e temperatura da água foram obtidos semanalmente. Os valores médios semanais de temperatura mínima absoluta atmosférica foram calculados através dos dados obtidos pela Estação Meteorológica CEAPLA/UNESP, localizado a aproximadamente 500 metros do local do experimento. Semanalmente as plantas foram pesadas e posteriormente devolvidas as respectivas unidades experimentais. Variações de temperatura atmosférica foram verificadas. O período com os menores valores de temperatura mínima atmosférica (junho e julho) coincidem com o período de menores valores de ganho de biomassa do vegetal. Após este período, os valores de temperatura aumentaram favorecendo o crescimento do vegetal, ocorrendo os maiores valores de ganho de biomassa.

Abstract:
Abstract Aquatic Animal Monitoring Systemis initiated as part of PTTEP's Ocean for Life strategy as we thrive in enhancing Ocean Health & Biodiversity Monitoring to ensure that PTTEP's offshore operations are friendly and safe to the surrounding environment and aquatic animals. The basis of the Aquatic Animal Monitoring Systemproject focuses on conservation survey and tracking of rare aquatic animals as well as marinebiodiversity. As part of the process, an underwater camera was installed on a jacket leg of PTTEP's platform to allow the video recording of underwater lives. The video footage was then analyzed by Artificial Intelligence (AI)software using an object detection method for determining the animal's categorization, then using machine learning algorithm for more accuracy. This concept can visualize aquatic animals around the platform and the surrounding environment. Moreover, the AI software can shorten the video by cutting off any non-life appearing period. Therefore, this technique can support a processor during the video analysis from the platform, contributing to a better work efficiency as it can save time, manpower, and most importantly cost. For the detection algorithm, all targets generatea large amount of data in the form of images with labels in order to train a software to memorize the target objects. The AI software was able to detect and identify nine species of aquatic animals which are fish, turtle, whale, dolphin, shark, seal, sea lion, stingray, and seahorse. With AI software in place, the video raw file can be shortened up to 85% by removing non-life periods in the original video and tracking only animal life in the video frame. This is a significant milestone for PTTEP in creating sustainable values to the ocean, which is considered as PTTEP's second home. Adopting artificial intelligence and machine learning technology to this project, it helps categorizing aquatic animal types and shorten a videofile. Moreover, it can save manpower and time.

Abstract:
Global nutrition needs are increasing and aquatic foods have recently been identified as crucial in addressing many of the world’s urgent challenges, including hunger and malnutrition. This synthesis highlights the importance of aquatic foods as a source of protein, micronutrients and income, its potential to meet increasing food demands, as well as the challenges in aquatic food production and harvesting. Most importantly, it provides an overview of management initiatives and innovative solutions for secured sustainable access to aquatic foods in the future. Aquatic foods provide micronutrient-rich foods for 3.3 billion people and support the livelihoods of more than 800 million people. Small-scale fisheries, in particular, play a key role in supporting the diversity and nutritional benefits of aquatic foods. However, the capture and production of aquatic foods is not always sustainable, and access to these foods may be unequal. At the water-land nexus, new ways of producing aquatic foods hold the potential to reduce the climate footprint in the food system. The governance of, and investment in, aquatic food systems needs to aim to preserve, support and improve aquatic species diversity and to improve access to this highly nutritious food. These efforts need to include multiple stakeholders, such as fishers, community agencies, policy makers and researchers, and be firmly established in both the latest research and in a local/regional context - ecologically and socially. By incorporating different aspects of aquatic foods, this synthesis aims to inspire and inform the reader about the importance of these systems, and means for a sustainable way forward.
