    Walkinshaw, C. H.

    1971-01-01

    Discussion of the role that lunar horticulture may fulfill in helping establish the life support system of an earth-independent lunar colony. Such a system is expected to be a hybrid between systems which depend on lunar horticulture and those which depend upon the chemical reclamation of metabolic waste and its resynthesis into nutrients and water. The feasibility of this approach has been established at several laboratories. Plants grow well under reduced pressures and with oxygen concentrations of less than 1% of the total pressure. The carbon dioxide collected from the lunar base personnel should provide sufficient gas pressure (approx. 100 mm Hg) for growing the plants.

    2014-05-19

    Horticultural therapy is defined as the process of utilising fruits, vegetables, flowers and plants facilitated by a trained therapist or healthcare provider, to achieve specific treatment goals or to simply improve a person's well-being. It can be used for therapy or rehabilitation programs for cognitive, physical, social, emotional, and recreational benefits, thus improving the person's body, mind and spirit. Between 5% to 15% of people with schizophrenia continue to experience symptoms in spite of medication, and may also develop undesirable adverse effects, horticultural therapy may be of value for these people. To evaluate the effects of horticultural therapy for people with schizophrenia or schizophrenia-like illnesses compared with standard care or other additional psychosocial interventions. We searched the Cochrane Schizophrenia Group Trials Register (Janurary 2013) and supplemented this by contacting relevant study authors, and manually searching reference lists. We included one randomised controlled trial (RCT) comparing horticultural therapy plus standard care with standard care alone for people with schizophrenia. We reliably selected, quality assessed and extracted data. For continuous outcomes, we calculated a mean difference (MD) and for binary outcomes we calculated risk ratio (RR), both with 95% confidence intervals (CI). We assessed risk of bias and created a 'Summary of findings' table using the GRADE (Grades of Recommendation, Assessment, Development and Evaluation) approach. We included one single blind study (total n = 24). The overall risk of bias in the study was considered to be unclear although the randomisation was adequate. It compared a package of horticultural therapy which consisted of one hour per day of horticultural activity plus standard care with standard care alone over two weeks (10 consecutive days) with no long-term follow-up. Only two people were lost to follow-up in the study, both in the horticultural therapy group (1 RCT

    2009-10-15

    This paper provided details of a hybrid taxi pilot program conducted to compare the on-road performance of Toyota Camry hybrid vehicles against conventional vehicles over a 1-year period in order to determine the business case and air emission reductions associated with the use of hybrid taxi cabs. Over 750,000 km worth of fuel consumption was captured from 10 Toyota Camry hybrids, a Toyota Prius, and 5 non-hybrid Camry vehicles over an 18-month period. The average real world fuel consumption for the taxis demonstrated that the Toyota Prius has the lowest cost of ownership, while the non-hybrid Camry has the highest cost of ownership. Carbon dioxide (CO{sub 2}) reductions associated with the 10 Camry hybrid taxis were calculated at 236 tonnes over a 7-year taxi service life. Results suggested that the conversion of Toronto's 5680 taxis would yield annual CO{sub 2} emission reductions of over 19,000 tonnes. All hybrid purchasers identified themselves as highly likely to purchase a hybrid again. 5 tabs., 9 figs.

  15. Toronto green roof construction standard

    International Nuclear Information System (INIS)

    Aster, D.

    2007-01-01

    Toronto City Council adopted a green roof strategy in February 2006. This paper reviewed the by-law governing the strategy as well as the work in progress to develop minimum standards for the design and construction of green roofs in Toronto. The strategy included a series of recommendations regarding the installation of green roofs on city buildings; a pilot grant program; using the development process to encourage green roofs; and, public education and promotion. It was noted that compared to Europe, the development of standards for green roofs in North America is in its early stages. As an emerging sustainable technology, there currently are no standards incorporated into Ontario's Building Code against which Toronto can measure the design and construction of green roofs. Therefore this paper included an analysis detailing how the recommended design requirements were able to support the City's green roof policy objectives and integrate the performance criteria for green roofs previously established and supported by Toronto City Council. The key policy objectives of the City's green roof strategy were to reduce the urban heat island effect; to address stormwater management implications in terms of quality and quantity; to improve the energy budgets of individual buildings; and, to improve air quality

  19. Toronto Hydro annual report, 1992

    International Nuclear Information System (INIS)

    1993-01-01

    Toronto Hydro is the electric utility serving about 219,000 customers in Toronto, Ontario. In 1992, the utility purchased 9.6 billion kWh of electricity from Ontario Hydro, down 3.6% from 1990. Energy sales totalled 9.2 billion kWh, down 4.1% from 1990. Retail electricity rates increased an average of 6.7% in 1992, in spite of an increase in Ontario Hydro's wholesale rate by 8.2%, due to better than anticipated financial results and cost-control measures. The decline in electricity purchases and sales are attributed to economic factors, which also contributed to an increase in the utility's provision for bad debts. The third year of a 13.8-kV conversion project was completed in 1992; this project is converting the existing 4 kV distribution system to the higher voltage since maintenance and repair of the existing system is costly and the equipment is becoming less reliable. New construction, refurbishing, and modernization of equipment were performed at a number of substations. Other improvements in 1992 are reported in the areas of management and engineering systems, personnel policies, work safety, and energy management. Financial statements are included. 11 figs., 4 tabs

    2018-04-01

    This study developed evaluation scales for measuring the effects of horticultural therapy in practical settings. Qualitative and quantitative research, including three preliminary studies and a main study, were conducted. In the first study, a total of 779 horticultural therapists answered an open-end questionnaire based on 58 items about elements of occupational therapy and seven factors about singularity of horticultural therapy. In the second study, 20 horticultural therapists participated in in-depth interviews. In the third study, a Delphi method was conducted with 24 horticultural therapists to build a model of assessment indexes and ensure the validity. In the final study, the reserve scales were tested by 121 horticultural therapists in their practical settings for 1045 clients, to verify their reliability and validity. Preliminary questions in the effects area of horticultural therapy were developed in the first study, and validity for the components in the second study. In the third study, an expert Delphi survey was conducted as part of content validity verification of the preliminary tool of horticultural therapy for physical, cognitive, psychological-emotional, and social areas. In the final study, the evaluation tool, which verified the construct, convergence, discriminant, and predictive validity and reliability test, was used to finalise the evaluation tool. The effects of horticultural therapy were classified as four different aspects, namely, physical, cognitive, psycho-emotional, and social, based on previous studies on the effects of horticultural therapy. 98 questions in the four aspects were selected as reserve scales. The reliability of each scale was calculated as 0.982 in physical, 0.980 in cognitive, 0.965 in psycho-emotional, and 0.972 in social aspects based on the Cronbach's test of intra-item internal consistency and half reliability of Spearman-Brown. This study was the first to demonstrate validity and reliability by simultaneously

    Pengelly, D [McMaster Inst. of Environment and Health, Hamilton, ON (Canada); Campbell, M; Macfarlane, R; Li-Muller, A [Toronto Public Health, ON (Canada)

    2001-10-01

    Based on data acquired in the year 1995, Toronto Public Health published a report called Air Pollution Burden of Illness in Toronto. In that report, it was estimated that up to 1000 Toronto residents die prematurely each year while another 5500 are admitted to hospitals due to six smog-related air pollutants. In the present document, the authors examined the air quality classifications of the Ontario Air Quality Index (AQI) in an attempt to determine whether the values adequately reflect the state of air quality and the associated burden of illness in Toronto. After careful examination of the results, it became apparent that 92 per cent of the premature mortality and hospitalization took place at times when the Air Quality Index was in the very good or good range. At times when the Air Quality Index was in the moderate or poor-very poor range, an estimated 8 per cent of the burden of illness occurred. These results indicate that the concentration range of a pollutant used to classify the good and very good categories is not always in agreement with the pollutant levels responsible for the adverse health effects. As demonstrated by this study, the air quality associated with the very good or good range described by the AQI is responsible for negative health effects in Toronto, and are lower than the provincial criteria of Ontario. The air quality conditions that may have an impact on health are not always correctly identified by the current AQI system. The authors are recommending a review of the provincial criteria for several air pollutants, and the current AQI system needs to be modified. 16 refs., tabs., figs.

    This paper examines Pakistan's competitiveness in export of selected horticulture commodities by employing set of revealed comparative advantage (RCA) and revealed competitive advantage indices with respect to global trade. Results demonstrate that Pakistan has comparative and competitive advantage over the period under analysis and indicates a transition from comparative and competitive disadvantage to comparative and competitive advantage during the period under analysis. Tangerines, mandarins, clem have maintained relatively higher revealed comparative advantage as compared to other categories for the whole period under analysis. Onion export has revealed comparative advantage with some fluctuations over time. The research indicates that Pakistan's comparative and competitive advantages have been increasing in all the selected commodities during period under analysis which indicates the potential of horticulture exports for foreign exchange earnings. There is need to strengthen comparative and competitive advantage in horticulture sector by policy support and facilitating role by all stakeholders. (author)

About 20.2 million m 3 of horticultural peat was produced in 1997 in Western Europe and about 9.5 million m 3 in Northern America. The share of Eastern Europe was 2.9 million m 3 . Production of fuel peat and horticultural peat in Europe are nearly equal, but most of the countries produce only horticultural peat. Finland, Russia, Ireland, Belorussia and Sweden are countries where the share of fuel peat is high. The largest producers of horticultural peat are Germany, Canada and Estonia. The share of these countries is about 60% of the production in Europe and Northern America. Germany and Canada do not produce fuel peat at all, and in Estonia the main portion of peat production area is aimed at horticultural production. About 1.6 million m 3 of horticultural peat was produced in Finland in 1997, corresponding to about 8% of the horticultural peat production in Europe. The share of horticultural peat has been low also in Ireland and Sweden. The main portion of the horticultural peat production in Finland is produced side by side with the fuel peat production. Horticultural peat is exported mainly as processed and sacked peat. The horticultural peat production in Western Europe is about 20 million m 3 /s. The Netherlands is a were large consumer of horticultural peat, but it has no horticultural peat production of its own. Other possible countries for export are Spain and France in Europe, and Japan

  8. Smart meter status report from Toronto

    International Nuclear Information System (INIS)

    O'Brien, D.

    2006-01-01

    An update of Toronto Hydro's smart metering program was presented. Electricity demand is expected to keep increasing, and there is presently insufficient generation to match supply needs in Ontario. The smart metering program was introduced to aid in the Ontario government's energy conservation strategy, as well as to address peak supply problems that have led to power outages. It is expected that the smart metering program will reduce provincial peak supply by 5 per cent, as the meters support both time-of-use rates and critical peak pricing. Over 800,000 smart meters will be supplied to customers by 2007, and all 4.3 million homes in Toronto will have a smart meter by 2010. In order to meet targets for 2010, the utility will continue to install more 15,000 meters each month for the next 4 years. While the Ontario government has planned and coordinated the rollout and developed smart metering specifications and standards, Toronto Hydro is responsible for the purchase, installation, operation and maintenance of the meters. Advance testing of each meter is needed to ensure billing accuracy, and customer education on meter use is also. The complexity of the metering program has led the utility to establish a rigid project management process. Customer education pilot program are currently being conducted. Experience gained during the earlier phases of the program have enabled the utility to select appropriate metering systems based on density, topography and physical conditions. Project expenditures have been within budget due to improved project estimating and planning. The metering program has been conducted in tandem with the utility's peakSAVER program, a residential and small commercial load control program that has been successful in reducing summer peak demand by cycling air conditioners without causing discomfort. It was concluded that the utility will continue with its mass deployment of smart meters, and is currently preparing its call center to handled

    In the case of horticultural produce, the usefulness of irradiation is selective and irradiation may be most beneficial when used in conjunction with other preservative treatments such as mild refrigeration. Big benefits may be derived from energy saving in the degree of chilling required, in extended shelf-life and in quality retention with particular reference to mushrooms and strawberries. Research in the Irish context is urgently required

    Full Text Available

    Horticultural crops include a wide range of commodities, such as fruits and vegetables that are highly valuable for humanity. They are extensively grown worldwide, and their production can be described as an open and highly complex system affected by many factors, among which we can count weather, soil and cropping system, as well as the interaction between these factors. The aim of environmental physiology is to characterize the interaction between environmental stress and crop response, in order to maximize both yield quantity and quality. This review presents the most recent findings about the effects of the main abiotic environmental factors (light, temperature, and water on whole plant physiology of horticultural crops. Environmental stresses can cause morpho-anatomical, physiological and biochemical changes in crops, resulting in a strong profit reduction. A clear understanding of environmental factors and their interaction with physiological processes is extremely important for improving horticultural practices (irrigation, light management, mineral nutrition, greenhouse design, etc., optimizing photosynthetic carbon assimilation and increasing fruit productivity and crop quality. In addition, the information obtained by ecophysiological studies can be incorporated into breeding programs or agricultural zoning strategies.

    The radon testing survey in Metropolitan Toronto public schools was the most intensive project of its kind ever undertaken in Canadian schools. It also included an extensive public education program on radiation and radon-in-schools. The radon levels at 632 schools were measured using the CAIRS Radon Monitors. Ninety percent of the locations measured were found to have a radon level equal to or less than 2 mWL. Two locations in two different schools were found to have a radon level at or above the Action Level (20 mWL). The remaining results were between the two extremes. Follow-up testing in those schools where more than 10 mWL of radon was found is in progress. (author)

    Studies were made to understand some of the horticultural problems like causes of lag phase in Pusa seedless grapes and phenomenon of self-incompatibility in mango through radiotracer technique. An examination of the phosphorus content and movement of 32 P in Pusa seedless grapes revealed that phosphorus mobilization between leaves and berries is considerably affected by the developmental stages of barries. Data regarding self-incompatibility in mango pointed out that there was preferential movement of nutrients in cross pollinated fruitlets as compared to self-pollinated ones. (author)

It is also selling natural gas to 10,000 commercial customers. EPCOR now is interested in acquiring the customer base from Apollo Gas Marketing, a Toronto-based marketer recently forced out of the Alberta market by rising gas prices. EPCOR is eager to learn from the mistakes made by Apollo and other natural gas marketers and is putting together a contract package that would ensure a reasonable profit on operations even in the face of rising gas prices. Customers are offered the opportunity to sign fixed term contracts for one -, three-, or five years. The one year contract has a price tag of $6.75/gigajoule; the three-year term is priced at $5.99/gigajoule, and the five-year contract at $5.35/gigajoule. While the one-year price is a little high, compared to contracts available from other marketers, EPCOR's five-year term is worth customers' attention.

  11. The social dimensions of therapeutic horticulture.

    2017-07-01

    Harnessing nature to promote mental health is increasingly seen as a sustainable solution to healthcare across the industrialised world. The benefits of these approaches to well-being include reduced symptoms of anxiety, depression and improved social functioning. Many studies assume that contact with nature is the main therapeutic component of these interventions yet 'green care' programmes typically include activities not based on 'nature' that may contribute to positive outcomes. This study explored the views of service users participating in a Therapeutic Horticultural programme on what factors promoted their engagement in the project, to identify variables other than 'nature' that may be responsible for successful engagement in these programmes. A secondary aim was to assess the significance 'nature' plays including, for example whether a prior interest in horticultural-related activities, such as gardening, is significant. Two focus groups were held with mental health service users (n = 15) attending a gardening project in south-east England. Findings revealed that the social element of the project was the key facilitator to engagement; the flexible structure of the gardening project was also significant and allowed service users to feel empowered. 'Nature' evoked a sense of calm and provided participants with a non-threatening space that was engaging. © 2017 John Wiley & Sons Ltd.

    This project aimed the characterization of the physical workload of the organic horticulture by determining the frequency of exposure of operators to some activity categories. To do this, an adaptation of the PATH method (Posture, Activities, Tools and Handling) was done to be used in the context of agriculture work. The approach included an evaluation of physical effort demanded to perform the tasks in the work systems from an systematic sampling of work situations from a synchronized monitoring of the heart rate; a characterization of posture repertoire adopted by workers by adapting the OWAS method; an identification of pain body areas using the Corlett diagram; and a subjective evaluation of perceived effort using the RPE Borg scale. The results of the individual assessments were cross correlated and explained from an observation of the work activity. Postural demands were more significant than cardiovascular demands for the studied tasks, and correlated positively with the expressions of bodily discomfort. It is expected that, besides the knowledge obtained of the physical effort demanded by organic horticulture, this project will be useful for the development of new technologies directed to minimize the difficulties of the human work and to raise the work productivity.

    2011-12-01

    Full Text Available Horticulture in Argentina is an activity with great potential whose history has mainly been driven by Italian immigrants who arrived during the last two centuries. It is a valuable complement for traditional primary productions on which the country is focused with more than 30 millions of cultivated hectares and different agro-climatic conditions that characterize the different horticultural regions distributed throughout the country. The aim of this article is to give a panorama of the history, reality and perspectives in Argentina of an activity that is an opportunity for producers and entrepreneurs interested in it. Due to its characteristics, horticulture generates and dynamizes employment with great importance for regional economies. The proportion between vegetables and fruit produced and commercialized in Argentina is 63 and 34% respectively. Horticultural products for exportation largely are garlic, onion and beans. Concerning the most commercialized vegetables in Argentina, potato, tomato, onion, squash, lettuce, pepper, marrow and sweet potato stand out, whereas orange, tangerine, apple, banana, lemon, pear, grape and grapefruit may be highlighted among fruit. At present, the main challenge of the Argentinian horticultural sector is given not only by the possibilities of productive diversification and the expansion of the productive area but also of the technological level optimization, the application of quality norms and the agro-industry growth.

    2018-03-05

    The number of alien plants escaping from cultivation into native ecosystems is increasing steadily. We provide an overview of the historical, contemporary and potential future roles of ornamental horticulture in plant invasions. We show that currently at least 75% and 93% of the global naturalised alien flora is grown in domestic and botanical gardens, respectively. Species grown in gardens also have a larger naturalised range than those that are not. After the Middle Ages, particularly in the 18th and 19th centuries, a global trade network in plants emerged. Since then, cultivated alien species also started to appear in the wild more frequently than non-cultivated aliens globally, particularly during the 19th century. Horticulture still plays a prominent role in current plant introduction, and the monetary value of live-plant imports in different parts of the world is steadily increasing. Historically, botanical gardens - an important component of horticulture - played a major role in displaying, cultivating and distributing new plant discoveries. While the role of botanical gardens in the horticultural supply chain has declined, they are still a significant link, with one-third of institutions involved in retail-plant sales and horticultural research. However, botanical gardens have also become more dependent on commercial nurseries as plant sources, particularly in North America. Plants selected for ornamental purposes are not a random selection of the global flora, and some of the plant characteristics promoted through horticulture, such as fast growth, also promote invasion. Efforts to breed non-invasive plant cultivars are still rare. Socio-economical, technological, and environmental changes will lead to novel patterns of plant introductions and invasion opportunities for the species that are already cultivated. We describe the role that horticulture could play in mediating these changes. We identify current research challenges, and call for more

The three main categories of indoor horticulture were investigated: supplemented greenhouses, which use electric lighting to extend the hours of daylight, supplement low levels of sunlight on cloudy days, or disrupt periods of darkness to alter plant growth; non-stacked indoor farms, where plants are grown in a single layer on the floor under ceiling-mounted lighting; and vertical farms, where plants are stacked along vertical shelving to maximize grow space, and the lighting is typically mounted within the shelving units.

  8. Typical horticultural products between tradition and innovation

    Directory of Open Access Journals (Sweden)

    Innocenza Chessa

    Full Text Available Recent EU and National policies for agriculture and rural development are mainly focused to foster the production of high quality products as a result of the increasing demand of food safety, typical foods and traditional processing methods. Another word very often used to describe foods in these days is “typicality” which pools together the concepts of “food connected with a specific place”, “historical memory and tradition” and “culture”. The importance for the EU and the National administrations of the above mentioned kind of food is demonstrated, among other things, by the high number of the PDO, PGI and TSG certificated products in Italy. In this period of global markets and economical crisis farmers are realizing how “typical products” can be an opportunity to maintain their market share and to improve the economy of local areas. At the same time, new tools and strategy are needed to reach these goals. A lack of knowledge has being recognized also on how new technologies and results coming from recent research can help in exploiting traditional product and in maintaining the biodiversity. Taking into account the great variety and richness of typical products, landscapes and biodiversity, this report will describe and analyze the relationships among typicality, innovation and research in horticulture. At the beginning “typicality” and “innovation” will be defined also through some statistical features, which ranks Italy at the first place in terms of number of typical labelled products, then will be highlighted how typical products of high quality and connected with the tradition and culture of specific production areas are in a strict relationship with the value of agro-biodiversity. Several different examples will be used to explain different successful methods and/or strategies used to exploit and foster typical Italian vegetables, fruits and flowers. Finally, as a conclusion, since it is thought that

    This annual Smog Report Card for Toronto evaluates the progress made by the City toward reducing the environmental and health impacts of smog. The final grade for the City in 2005 was a C-, a decrease over the B+ issued in 2004. The report card evaluates City Council actions based on their clean air commitments. In particular, the performance on initiatives in the following six major areas were graded: energy; transit; walking and biking; fleets and fuels; intergovernmental action; and new air quality strategies. Although Toronto had a record number of smog days due to high-temperatures and high pollution levels, it had a better record on smog and climate change than either the provincial or federal levels. Greenhouse gas emissions in Toronto are actually going down, but they are up 12 and 24 per cent at the federal and provincial levels respectively. In 2005, the City of Toronto developed a new Air Quality Management Strategy to replace the Smog Plan. Future evaluations will depend on whether the strategy is effective. The report recommends that efforts should be made to reduce greenhouse gas emissions which cause global warming, as well measures to reduce the urban heat island effect by planting trees, improving energy efficiency and using lighter-coloured materials for roads, parking lots and roofs. The report card criticized that there has been no green power purchased for the City and that the transit ridership growth strategy is behind schedule. It also noted that the City is not pedestrian or bike friendly. refs., tabs., figs.

    This paper examined the health impacts of air pollution from traffic in Toronto. The paper provided a review of scientific studies on the health effects of vehicle pollution as well as a quantitative assessment of the economic costs and the burden of illness attributed to traffic pollution in Toronto. The report also assessed air pollution and traffic trends in the city, and outlined initiatives being conducted to reduce vehicle-related pollution. The study used the new air quality benefits tool (AQBAT) which determines the burden of illness and the economic impacts of traffic-related air pollution. Air modelling specialists were consulted in order to determine the contribution of traffic-related pollutants to overall pollution levels using data on traffic counts and vehicle emissions factors. The air model also considered dispersion, transport and and the transformation of compounds emitted from vehicles. Results of the study showed that traffic pollution caused approximately 440 premature deaths and 1700 hospitalizations per year. Children in the city experienced more than 1200 acute bronchitis episodes per year as a result of air pollution from traffic. Mortality-related costs associated with traffic pollution in Toronto were estimated at $2.2 billion. It was concluded that the city must pursue the implementation of sustainable transportation policies and programs which foster and enable the expansion and use of public transport. 47 refs., 8 tabs., 9 figs

    1997-01-01

    In October 1997, over 200 participants attended the First Mayan Women's Congress in Mexico and called for financial assistance, capacity building, and training to help Mayan women escape poverty. The Congress was initiated by the UN Development Fund for Women in collaboration with the Small Grants Program of the UN Development Program. Traditionally, Mayan women and men have played distinct roles in society, and efforts are underway to increase gender sensitivity and achieve a new balance of power. Mayan women attending the Congress reported that they face daily challenges in gaining their husbands' approval for participation in income-generating activities outside of the home. Eventually, however, some husbands also start working in these enterprises and are learning to assume their share of domestic responsibilities. Mayan women have been forced to reevaluation their role in society by a prevailing agricultural and environmental crisis as well as a high unemployment rate. Crafts that were once produced only for household consumption are now considered for export. Because the women need funds to initiate income-generating activities, the Conference linked women's groups with development practitioners, policy-makers, and donors. The women requested financial aid for more than 30 specific projects, and Congress participants agreed to pursue innovate strategies to support the enterprises with funds, training, and technical assistance. The Congress also encouraged environmental nongovernmental organizations to include Mayan women in mainstream development activities. This successful Congress will be duplicated in other Mexican states.

  10. Toronto smog report card 2003 : final grade C -

    International Nuclear Information System (INIS)

    2003-10-01

    An annual Smog Report Card for Toronto has been published annually by the Toronto Environmental Alliance since 1997, evaluating the progress made by the City toward reducing the environmental and health impacts of smog. The final grade for the City in 2003 was a C -, an improvement over last year's D +. The evaluation examined the performance on 33 initiatives in six major areas: leadership, transit, electricity, fleets and fuels, bikes and pedestrians, and public education. Issues that stood out were: a $30 million increase in funding to the Toronto Transit Commission (TTC), and the release of the TTC's Ridership Growth Strategy depicting how transit ridership can be increased through improved service and lower fares. The drive-through and pesticide by-laws were passed by Council, which should result in smog reduction from unnecessary activities. Leadership was found to be lacking at City Hall in the area of clean air, in view of its decision to proceed with the expansion of Island Airport. The decision to move forward on only 20 per cent of planned green power and energy efficiency measures was a low point in 2002. The City's budget process, which effectively screened out most environmental initiatives was in part responsible for the lack of progress. The following grades were awarded: transit and trip reduction (B), energy efficiency and green power received (D), fleets and fuels (C), bikes and pedestrians (C), public education (B). Recommendations for next year included: implementation of the TTC's Ridership Growth Strategy; creation of a Smog Plan Implementation Fund of $20 million per year to invest in energy efficiency, green fleets, green power and other related measures; and stop the expansion of Island Airport

  11. Consulting Whom? Lessons from the Toronto Urban Aboriginal Strategy

    Directory of Open Access Journals (Sweden)

    Mai T. Nguyen

    2014-04-01

    Full Text Available The research conducted here looks at the current Urban Aboriginal Strategy (UAS in Toronto. The purpose of this Strategy is to provide long-term investments to support Aboriginal communities in urban settings by focusing on three priority areas: improving life skills; promoting job training, skills, and entrepreneurship; and supporting Aboriginal women, children, and families. This article seeks to answer the following question: Does the UAS provide Aboriginal participants with the ability to effectively participant in the consultation process? It argues that the UAS process of consulting with the urban Aboriginal community does not allow for the effective participation of Aboriginal peoples because of problematics related to consulting in an urban setting and despite the language of partnership, the federal government still reserves the right to make final decisions. These problems diminish the ability to build renewed Aboriginal-State relations based on mutual respect and trust, which has been absent within the Aboriginal-State apparatus and resulted in the political exclusion of Aboriginals in Canada. Though consultation can be a vehicle for empowering participants with decision-making authority, this is not the case in Toronto. The lack of a common vision, political buy-in, and the aura of secrecy leads to a political relationship built on mistrust. Mistrust between members and government renders the consultation process ineffective. This article combines the literature on public consultations with official government documents to identify critical components that must be evident for consultations to be fruitful and participation effective. These criteria are the benchmarks upon which to measure effectiveness. Based on interviews with the Steering Committee, this article finds that the UAS process of consulting with the Toronto Aboriginal community does not enable Aboriginal participants to effectively participate in the democratic process.

    2011-01-01

    Charles Darwin's scientific paradigm was largely welcomed in Canadian academic biology and medicine, while reaction among other faculty and laypeople ranged from interest to outrage. In 1874, Ramsay Wright, a Darwinian-era biologist from Edinburgh, was appointed to the University of Toronto's Chair of Natural History. Over his 38-year career Wright integrated the evolutionary perspective into medical and biology teaching without accentuating its controversial source. He also applied the emerging German experimental research model and laboratory technology. This study identifies five categories of scientific and personal influences upon Wright through archival research on biographical sources and his writings.

    With the development of direct detection radiocarbon dating, which uses an accelerator as part of a highly selective mass spectrometer, it is now possible to determine the age of milligram samples of organic materials1-5. One application of accelerator dating is in evaluating scanty, sometimes controversial evidence for early horticulture throughout the world. We have now used the technique to date small samples of carbonized, cultivated plant remains from archaeological sites in Illinois. The results, reported here, establish (1) that squash was introduced by 7,000 yr ago, 2,500 yr before eastern North American records previously reported; (2) that horticulture involving indigenous plants had begun by 4,000 BP in eastern North America with domestication of Iva annua, a small-seeded annual; (3) that anomalous discoveries of Archaic period maize represent contaminants; and (4) that introduction of maize by initial Middle Woodland times (~2,000 BP) is questionable.

    Full Text Available Molecular cytogenetic techniques, such as in situ hybridization methods, are admirable tools to analyze the genomic structure and function, chromosome constituents, recombination patterns, alien gene introgression, genome evolution, aneuploidy, and polyploidy and also genome constitution visualization and chromosome discrimination from different genomes in allopolyploids of various horticultural crops. Using GISH advancement as multicolor detection is a significant approach to analyze the small and numerous chromosomes in fruit species, for example, Diospyros hybrids. This analytical technique has proved to be the most exact and effective way for hybrid status confirmation and helps remarkably to distinguish donor parental genomes in hybrids such as Clivia, Rhododendron, and Lycoris ornamental hybrids. The genome characterization facilitates in hybrid selection having potential desirable characteristics during the early hybridization breeding, as this technique expedites to detect introgressed sequence chromosomes. This review study epitomizes applications and advancements of genomic in situ hybridization (GISH techniques in horticultural plants.

    The third TEAM Workshop of the third round was held at Ontario Hydro in Toronto 25--26 October 1990, immediately following the Conference on Electromagnetic Field Computation. This was the first Joint Workshop with ACES (Applied Computational Electromagnetics Society), whose goals are similar to TEAM, but who tend to work at higher frequencies (Antennas, Propagation, and Scattering). A fusion problem, the eddy current heating of the case of the Euratom Large Coil Project Coil, was adapted as Problem 14 at the Oxford Workshop, and a solution to that problem was presented at Toronto by Oskar Biro of the Graz (Austria) University of Technology. Individual solutions were also presented for Problems 8 (Flaw in a Plate) and 9 (Moving Coil inside a Pipe). Five new solutions were presented to Problem 13 (DC Coil in a Ferromagnetic Yoke), and Koji Fujiwara of Okayama University summarized these solutions along with the similar number presented at Oxford. The solutions agreed well in the air but disagreed in the steel. Codes with a formulation in magnetic field strength or scalar potential underestimated the flux density in the steel, and codes based on flux density or vector potential overestimated it. Codes with edge elements appeared to do better than codes with nodal elements. These results stimulated considerable discussions; in my view that was the most valuable result of the workshop

    This annual report card evaluated the progress made by the City of Toronto toward reducing the environmental and health impacts of smog. The final grade for 2006 was a C-, the same as for 2005. The highest grade of B+ was issued in 2004. The report card evaluated City Council actions based on their clean air commitments. Although the summer of 2006 was one of the best on record, with only 11 smog days, the grade of C- was issued because the performance of the City's Air Quality Improvement record was poor. Toronto Environmental Alliance strongly recommended that important changes be made to improve air quality, transit and waste disposal. It recommended that the City should address the real causes of unclean air, which are motor vehicle exhaust and toxic pollution. This report card graded the performance on initiatives in the following six major areas: energy; transit; air quality plan; walking and biking; fleets and fuels; and, intergovernmental action. The report recommended that efforts should be made to reduce greenhouse gas emissions which cause global warming. refs., tabs., figs.

    Ultisol soil is a marginal soil commonly used for palm oil cultivation in Indonesia, its very potential for cultivation of horticulture crops. The utilization of ultisol soil can be done with adding compost with certain proportions. The research aimed to know best proportion of ultisol soil and compost, and proportion of water concentration, and its relationship with fresh and dry weight of horticulture crops . The research was divided 3 steps. The first, mixed ultisol soil and compost with certain proportion and flooding until steady. The second, watering with different concentration to soil mixture. The last, studied its relationship with fresh and dry weight of crops. The result show that physical properties and nutrient content of ultisol soil was increasing with adding compost. SC4 (70% soil and 30% compost) is the best composition to soil mixture. Watering with different concentration show that trend decreased from reference and the bulk density and porosity decreased not significantly at the significant level ∝ = 0.05. Watering affect mass of pakcoynot significantly at the significant level ∝ = 0.05. Hence, ultisol soil was a potential marginal soil to utilizing as a media for cultivating horticulture crops.

  1. Fortifying Horticultural Crops with Essential Amino Acids: A Review.

    2017-06-19

    To feed the world's growing population, increasing the yield of crops is not the only important factor, improving crop quality is also important, and it presents a significant challenge. Among the important crops, horticultural crops (particularly fruits and vegetables) provide numerous health compounds, such as vitamins, antioxidants, and amino acids. Essential amino acids are those that cannot be produced by the organism and, therefore, must be obtained from diet, particularly from meat, eggs, and milk, as well as a variety of plants. Extensive efforts have been devoted to increasing the levels of essential amino acids in plants. Yet, these efforts have been met with very little success due to the limited genetic resources for plant breeding and because high essential amino acid content is generally accompanied by limited plant growth. With a deep understanding of the biosynthetic pathways of essential amino acids and their interactions with the regulatory networks in plants, it should be possible to use genetic engineering to improve the essential amino acid content of horticultural plants, rendering these plants more nutritionally favorable crops. In the present report, we describe the recent advances in the enhancement of essential amino acids in horticultural plants and possible future directions towards their bio-fortification.

  2. Cold hardiness research on agricultural and horticultural crops in Finland

    2008-12-01

    Full Text Available This paper represents an overview of cold hardiness research conducted on agricultural and horticultural crops, as well as on amenity plants in Finland. Inadequate freezing tolerance and/or winter hardiness often prevents introduction of new species and cultivars to Finland. Field observations on winter hardiness and more recently the results from laboratory freezing tests, have assisted breeders to select hardy genotypes. Research approaches for agricultural crops have evolved from observations on winter and frost damage to studies on molecular mechanisms of cold acclimation and freezing injury. The results of experiments on survival of winter cereals, grasses and clovers and frost tolerance of potato and turnip rape are discussed. The studies conducted on horticultural crops, including apple, strawberry, raspberry, currants, blueberry, sea buckthorn, perennial herbs as well as on ornamental trees and shrubs have included field evaluations of cultivars, or selections for winter hardiness, and studies on the effects of cultural management practices on winter survival. During the last decade detailed studies including controlled freezing tests have provided tools to assist in explanation of the underlying mechanisms of cold hardiness also in horticultural plants. ;

    Aim To present a narrative review of the empirical literature on the use of horticultural therapy in dementia care. Method A comprehensive literature search, conducted in December 2014, resulted in the selection of 15 primary research articles for review. Of these, three used qualitative methods, five used quantitative methods and seven used mixed methodology. The articles were critically appraised, and the narrative synthesis used a thematic approach whereby prominent themes from the articles were grouped to form representative themes. Findings Three main themes emerged from the narrative synthesis: the emotional health of people living with dementia, their perceived self-identity and their levels of engagement. Conclusion Horticultural therapy can be beneficial. At a macro-level, it is an inexpensive therapy that does not require specialist training to deliver. At a micro-level, it enhances the wellbeing of people living with dementia. Recommendations are made to promote access to appropriate horticultural therapy for people living with dementia, and for further research in this area.

    Flint, Douglas H

    2003-01-01

    This study has two objectives. First, to predict the outcomes of a public sector downsizing; second to measure effects of downsizing at organizational and inter-organizational levels. Primary data to assess the organizational level effects was collected through interviews with senior executives at two of Metro-Toronto's hospitals. Secondary data, to assess the inter-organizational effects, was collected from government documents and media reports. Due to the exploratory nature of the study's objectives a case study method was employed. Most institutional downsizing practices aligned with successful outcomes. Procedures involved at the inter-organizational level aligned with unsuccessful outcomes and negated organizational initiatives. This resulted in an overall alignment with unsuccessful procedures. The implication, based on private sector downsizings, is that the post-downsized hospital system was more costly and less effective.

    Although access to information on health services is particularly important for recent immigrants, numerous studies have shown that their use of information and referral services is limited. This study explores the role played by 2-1-1 Toronto in supporting recent immigrants. The study objectives were to (1) understand whether 2-1-1 Toronto is reaching and supporting recent immigrants and (2) gain a better appreciation of the information needs of this population group. A phone survey was conducted in 2005-2006 to collect information on 2-1-1 users' characteristics and levels of satisfaction. Survey data were compared (in 2006) with census data to assess their representativeness. To achieve Objective 2, semistructured qualitative interviews were conducted and analyzed in 2006-2007, with a subset of Spanish-speaking callers. Recent immigrants were overrepresented among 2-1-1 callers. However, the survey population was substantially younger and had higher levels of formal education than the general population. Health-related queries represented almost one third of the total. The survey showed very high levels of satisfaction with the service. Many interviewees described their first experiences with the Canadian healthcare system negatively. Most of them had relied on disjointed, low-quality information sources. They trusted 2-1-1 but had discovered it late. Results are mixed in terms of 2-1-1's support to immigrants. A significant percentage of users do not take full advantage of the service. The service could become the information "entry point" for recent immigrants if it was able to reach them early in the resettlement process. Proactive, community-oriented work and a more creative use of technology could help. Copyright © 2012 American Journal of Preventive Medicine. All rights reserved.

    This study assessed the psychopathological effects of participation in a 10-session horticultural therapy program in patients with schizophrenia. The study design was pre and post test design of experimental and control groups. Twenty-eight Korean patients with schizophrenia, recruited from a mental health clinic and two mental health rehabilitation centers in Suwon, South Korea, were voluntarily assigned to either a control group (average age: 33.4±9.4years) or a horticultural therapy group (average age: 42.1±13.0years). The participants in the horticultural therapy group participated in a 10-session horticultural therapy program designed around various plant cultivating activities. The horticultural therapy program involved sessions once a week from April 2017 to June 2017. A psychiatrist evaluated the psychopathological symptoms of schizophrenic patients in both groups. To assess the clinical psychopathological effects, the Korean version of the Positive and Negative Syndrome Scale (PANSS) and Brief Psychiatric Rating Scale (BPRS) were used. The horticultural therapy group significantly improved in terms of positive, negative, and general symptoms on the PANSS after the 10-session horticultural therapy program. Moreover, the horticultural therapy group significantly improved in terms of clinical symptoms of schizophrenia in BPRS after the 10-session horticultural therapy program. However, there was no change in the PANSS and BPRS scores in the control group. This study showed the potential of horticultural therapy in improving psychopathological symptoms in psychiatric patients. Future studies should investigate the effects of long-term horticultural therapy program on the chronic symptoms of patients with schizophrenia. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2008-03-01

    Full Text Available This paper seeks to evaluate the present and future prospects of developing and developed countries in agricultural exports in general and in horticultural exports in particular. The study also evaluates the behaviour of international export prices for agricultural commodities, both for developing and developed nations. In general, this study provides an insight into the direction in which various developed and developing countries are heading for insofar as their agricultural and horticultural exports are concerned in the changed market conditions. The study has made a few major observations. First, the study shows decline in market share of developing countries’ in world agricultural exports in the face of marginal increase in their market share in world fruits and vegetable (F&V exports during the period between 1981 and 1997. Second, although the study shows lower market share of developing countries’ in world F&V exports during the period between 1981 and 1997, the growth in F&V exports as proportion of total agricultural exports is noticed to be much faster for developing countries’ as against the developed countries’ during the same period. Third, though agricultural exports of Least Developed Countries (LDC have grown only marginally between 1981 and 1997, the growth in their F&V exports is seen to have been tremendous, especially after the late eighties period. Similarly, Socialist Countries of Asia (SCA and developing countries of Oceania have also shown sharp increases in their F&V exports after the late eighties period. Fourth, while except America, other Africa and Oceania, all the developing countries have shown decline in their market share in total F&V exports of Developing Market Economies (DME, Asia shows rise in its market share not only in agriculture but also in F&V exports of DME. Another major observation of this study is in terms of instabilities in export prices. The instabilities in export prices of agricultural

    Horticultural therapy is an adjunct therapy--to be used in addition to occupational and physical therapies, and combining means used by both. It is meant to increase the motivation of the physically and/or mentally handicapped, while at the same time stimulating the five senses and furnishing a means of self-gratification and self esteem. Now that neurologically orientated psychologists are identifying schizophrenia as being biologically based and capable of being reversed with exercise, it is time to study the many benefits of gardening as a therapy method.

    Horticultural crops data are organized by the Ministry of Agriculture, Republic of Indonesia. The data are presented annually in a tabular form and result a large data set. This situation makes users difficult to obtain summaries of horticultural crops data. This study aims to develop a clustering module in the SOLAP system for the distribution of horticultural crops in Indonesia and to visualize the results of clustering in a map using SpagoBI. The algorithm used for clustering is K-Means. Horticultural crops data include vegetables, ornamental plants, medicinal plants, and fruits from 2000 to 2013. The clustering module displays clustering results of horticultural crops in the form of text and table on SpagoBI. This module can also visualize the distribution of horticultural crops in the form of map on the HTML page. The application is expected to be useful for users in order to easily obtain summaries of the horticultural crops distribution data and its clusters. The summaries and clusters can be beneficial for the stakeholders to determine potential areas in Indonesia for horticultural crops.

    2012-12-01

    The first World Congress of Paediatric Cardiology was held in London, United Kingdom, in 1980, organised by Dr. Jane Somerville and Prof. Fergus Macartney. The idea was that of Jane Somerville, who worked with enormous energy and enthusiasm to bring together paediatric cardiologists and surgeons from around the world. The 2nd World Congress of Paediatric Cardiology took place in New York in 1985, organised by Bill Rashkind, Mary Ellen Engle, and Eugene Doyle. The 3rd World Congress of Paediatric Cardiology was held in Bangkok, Thailand, in 1989, organised by Chompol Vongraprateep. Although cardiac surgeons were heavily involved in these early meetings, a separate World Congress of Paediatric Cardiac Surgery was held in Bergamo, Italy, in 1988, organised by Lucio Parenzan. Thereafter, it was recognised that surgeons and cardiologists working on the same problems and driven by a desire to help children should really rather meet together. A momentous decision was taken to initiate a Joint World Congress of Paediatric Cardiology and Cardiac Surgery. A steering committee was established with membership comprising the main organisers of the four separate previous Congresses, and additional members were recruited in an effort to achieve numerical equality of cardiologists and surgeons and a broad geographical representation. The historic 1st "World Congress of Paediatric Cardiology and Cardiac Surgery" took place in Paris in June, 1993, organised by Jean Kachaner. The next was to be held in Japan, but the catastrophic Kobe earthquake in 1995 forced relocation to Hawaii in 1997. Then followed Toronto, Canada (2001, organised by Bill Williams and Lee Benson), Buenos Aires, Argentina (2005, organised by Horatio Capelli and Guillermo Kreutzer), and most recently Cairns, Australia (2009, organised by Jim Wilkinson). Having visited Europe (1993), Asia-Pacific (1997), North America (2001), South America (2005), and Australia (2009), and reflecting the "African Renaissance", the

    A geoinformation database for assessing soil resource potential for horticulture in Krasnodar region and Adygea has been developed. The results of geoinformation analysis indicate that only 55-60% of soils in these regions are suitable for growing horticultural crops without limitations; about 35-40% of the total soil area is unsuitable for horticultural purposes. For plum trees, the area of unsuitable soils is somewhat lower than for other horticultural crops. Geographically, the areas of soils suitable and unsuitable for horticulture are close to one another. The thickness of the loose earthy soil material, the gravel content, the degree of salinization, the soil texture, and the degree of soil hydromorphism are the major soil properties imposing considerable limitations for the development of fruit-growing industry in the studied regions. The highest portions of soils suitable for horticulture are found in Eiskii, Kushchevskii, Krylovskii, Shcherbinovskii, and Novokubanskii districts of Krasnodar region. The development of horticulture in Tuapsinskii, Slavyanskii, and Primorsko-Akhtarskii districts is limited because of the unsuitability of soils for this purpose. About 8% of the existing orchards are found on soils recognized as unsuitable for horticulture, and only about 20% of the existing orchards are found on soils suitable for fruit growing without limitations. About 70% of the existing fruit orchards are located on degraded soils or on soils with certain limitations for horticulture. The profitability of fruit orchards on such soils is lower than that of the orchards planted on soils without limitations for horticulture. This information is necessary for the adequate economic evaluation of the degree of soil degradation.

    Clinically depressed persons suffer from impaired mood and distortion of cognition. This study assessed changes in depression severity and perceived attentional capacity of clinically depressed adults (N=18) during a 12-week therapeutic horticulture program. The Beck Depression Inventory (BDI) and Attentional Function Index (AFI) were administered at baseline, twice during (4 and 8 weeks), and immediately after the intervention (12 weeks), and at a 3-month follow-up. Experiences of being away and fascination related to the intervention were measured at 4, 8, and 12 weeks. The mean BDI score declined 9.7 points from pretest (27.3) to posttest (p or =6) for 72% of the cases. The mean AFI score increased 10.2 points from pretest (68.8) to posttest (p = .06). The greatest change in BDI and AFI scores occurred in the initial weeks of the intervention. The reduction in BDI scores remained significant and clinically relevant at the 3-month follow-up (N=16). The decline in depression severity during the intervention correlated strongly with the degree to which the participants found that it captured their attention. Therapeutic horticulture may decrease depression severity and improve perceived attentional capacity by engaging effortless attention and interrupting rumination.

Таким образом, можно говорить о существенном медико-социальном значении этого заболевания. Даже в том случае, когда радикального хирургического вмешательства удается избежать, длительное и крайне дорогостоящее лечение трофических нарушений мягких тканей стоп и голеней ведет к огромным затратам как материальных средств, так и времени медицинского персонала.

    Full Text Available We interviewed eight University of Toronto (U of T instructors who have offered MOOCs on Coursera or EdX between 2012 and 2014 to understand their motivation for MOOC instruction, their experience developing and teaching MOOCs, and their perceptions of the implications of MOOC instruction on their teaching and research practices. Through inductive analysis, we gleaned common motivations for MOOC development, including expanding public access to high quality learning resources, showcasing U of T teaching practices, and attempting to engage MOOC learners in application of concepts learned, even in the face of constraints that may inhibit active learning in MOOC contexts. MOOC design and delivery was a team effort with ample emphasis on planning and clarity. Instructors valued U of T instructional support in promoting systematic MOOC design and facilitating technical issues related to MOOC platforms. The evolution of MOOC support at U of T grew from a focus on addressing technical issues, to instructional design of MOOCs driven, first, by desired learning outcomes. Findings include changes in teaching practices of the MOOC instructors as they revised pedagogical practices in their credit courses by increasing opportunities for active learning and using MOOC resources to subsequently flip their classrooms. This study addresses the paucity of research on faculty experiences with developing MOOCs, which can subsequently inform the design of new forms of MOOC-like initiatives to increase public access to high quality learning resources, including those available through U of T.

    2017-06-01

    Full Text Available The Greater Toronto Area (GTA is one of the most multicultural communities in the world. Frequently, this description is based on ethnic, linguistic, and culinary diversity. Physical cultural diversity, such as different sports, martial arts, forms of dance, exercise systems, and other physical games and activities, remains ignored and understudied. Based on a living database of the GTA’s physical cultural diversity, this study identifies the trajectories of the lifecycle of activities that have been introduced into the GTA’s physical culture by immigrants. These pathways differ based on whether the activity is offered in a separate setting, where individuals may be participating with other immigrants of the same ethnocultural group, or mixed settings, where people are participating with people from outside of their ethnocultural group. We argue that the diversity and the lifecycle trajectories of physical cultural forms in the GTA serve as evidence of interculturalism and the contribution by immigrants to the social and cultural life of Canada.

    Often the goal of health and social development agencies is to assess communities and work with them to improve community capacity. Particularly for health promoters working in community settings and to ensure consistency in the definition of health promotion, the evaluation of health promotion programmes should be based on strengths and assets, yet existing information for planning and evaluation purposes usually focuses on problems and deficits. A model and definition of community capacity, grounded in community experience and focusing on strengths and assets, was developed following a 4-year, multi-site, qualitative, action research project in four Toronto neighbourhoods. There was significant community involvement in the four Community Advisory Committees, one for each study site. Semi-structured, open-ended interviews and focus groups were conducted with 161 residents and agency workers identified by the Community Advisory Committees. The data were analyzed with the assistance of NUDIST software. Thematic analysis was undertaken in two stages: (i) within each site and (ii) across sites, with the latter serving as the basis for the development of indicators of community capacity. This paper presents a summary of the research, the model and the proposed indicators. The model locates talents and skills of community members in a larger context of socioenvironmental conditions, both inside and outside the community, which can act to enable or constrain the expression of these talents and skills. The significance of the indicators of community capacity proposed in the study is that they focus on identifying and measuring the facilitating and constraining socioenvironmental conditions.

    In this paper, we address the emergence of horticultural practice, agents, spaces and institutions in the two urban settings of Lisbon and Porto, in Portugal, during the second half of the nineteenth century. We do so by following the networking activities of two players: the self-made horticulturist and entrepreneur José Marques Loureiro, who created, in Porto, a commercial horticultural establishment and founded the Journal of Practical Horticulture; and the agronomist Francisco Simões Margiochi, head of the gardens and green grounds department of the municipality, who created the first course on gardening and horticulture, and founded the Royal Horticultural Society, both in Lisbon. Their joint activities were aimed at establishing horticulture as an applied science and to cater simultaneously to an extended audience of citizens. They enable us to enrich the narratives on the emergence and development of horticulture in Europe by calling attention to the participation in circulatory extended networks of actors who are often absent from these accounts. Additionally, they allow a comparative assessment of the outcome of their actions at the national level, and to understand their results in terms consonant with recent historiographical trends on the co-construction of centres and peripheries.

    The authors have now used direct detection radiocarbon dating (which uses an accelerator as part of a highly selective mass spectrometer) to date small samples of carbonized, cultivated plant remains from archaeological sites in Illinois. The results, reported here, establish (1) that squash was introduced by 7,000 yr ago, 2,500 yr before eastern North American records previously reported; (2) that horticulture involving indigenous plants had begun by 4,000 BP in eastern North American with domestication of Iva annua, a small-seeded annual; (3) that anomalous discoveries of Archaic period maize represent contaminants; and (4) that introduction of maize by initial Middle Woodland times (approx. 2,000 BP) is questionable.

    Two studies with single-group design (Study 1 N = 18, Study 2 N = 28) addressed whether horticultural activities ameliorate depression severity and existential issues. Measures were obtained before and after a 12-week therapeutic horticulture program and at 3-month follow-up. In both studies, depression severity declined significantly during the intervention and remained low at the follow-up. In both studies the existential outcomes did not change significantly; however, the change that did occur during the intervention correlated (rho > .43) with change in depression severity. Participants' open-ended accounts described the therapeutic horticulture experience as meaningful and influential for their view of life.

  5. Evaluating and optimizing horticultural regimes in space plant growth facilities

    Berkovich, Y.; Chetirkin, R.; Wheeler, R.; Sager, J.

    In designing innovative Space Plant Growth Facilities (SPGF) for long duration space f ightl various limitations must be addressed including onboard resources: volume, energy consumption, heat transfer and crew labor expenditure. The required accuracy in evaluating onboard resources by using the equivalent mass methodology and applying it to the design of such facilities is not precise. This is due to the uncertainty of the structure and not completely understanding of the properties of all associated hardware, including the technology in these systems. We present a simple criteria of optimization for horticultural regimes in SPGF: Qmax = max [M · (EBI) 2 / (V · E · T) ], where M is the crop harvest in terms of total dry biomass in the plant growth system; EBI is the edible biomass index (harvest index), V is a volume occupied by the crop; E is the crop light energy supply during growth; T is the crop growth duration. The criterion reflects directly on the consumption of onboard resources for crop production. We analyzed the efficiency of plant crops and the environmental parameters by examining the criteria for 15 salad and 12 wheat crops from the data in the ALS database at Kennedy Space Center. Some following conclusion have been established: 1. The technology involved in growing salad crops on a cylindrical type surface provides a more meaningful Q-criterion; 2. Wheat crops were less efficient than leafy greens (salad crops) when examining resource utilization; 3. By increasing light intensity of the crop the efficiency of the resource utilization could decrease. Using the existing databases and Q-criteria we have found that the criteria can be used in optimizing design and horticultural regimes in the SPGF.

    Ornamental horticulture has been identified as an important threat to plant biodiversity and is a major pathway for plant invasions worldwide. In this context, the family Cactaceae is particularly challenging because it is considered the fifth most threatened large taxonomic group in the world; several species are among the most widespread and damaging invasive species; and Cactaceae is one of the most popular horticultural plant groups. Based on the Convention on International Trade in Endangered Species of Wild Flora and Fauna and the 11 largest online auction sites selling cacti, we documented the international cactus trade. To provide an in-depth look at the dynamics of the industry, we surveyed the businesses involved in the cactus trade in South Africa (a hotspot of cactus trade and invasions). We purchased seeds of every available species and used DNA barcoding to identify species to the genus level. Although <20% of this trade involved threatened species and <3% involved known invasive species, many species were identified by a common name. However, only 0.02% of the globally traded cacti were collected from wild populations. Despite a large commercial network, all South African imports (of which 15% and 1.5% were of species listed as threatened and invasive, respectively) came from the same source. With DNA barcoding, we identified 24% of the species to genus level. Based on our results, we believe that if trade restrictions are placed on the small proportion of cacti that are invasive and there is no major increase in harvesting of native populations, then the commercial trade in cactus poses a negligible environmental threat. However, there are currently no effective methods for easily identifying which cacti are traded, and both the illicit harvesting of cacti from the wild and the informal trade in invasive taxa pose on-going conservation challenges. © 2017 Society for Conservation Biology.

    Objective: To determine whether people who have died from suicide in a large epidemiologic sample form clusters based on demographic, clinical, and psychosocial factors. Method: We conducted a coroner’s chart review for 2886 people who died in Toronto, Ontario, from 1998 to 2010, and whose death was ruled as suicide by the Office of the Chief Coroner of Ontario. A cluster analysis using known suicide risk factors was performed to determine whether suicide deaths separate into distinct groups. Clusters were compared according to person- and suicide-specific factors. Results: Five clusters emerged. Cluster 1 had the highest proportion of females and nonviolent methods, and all had depression and a past suicide attempt. Cluster 2 had the highest proportion of people with a recent stressor and violent suicide methods, and all were married. Cluster 3 had mostly males between the ages of 20 and 64, and all had either experienced recent stressors, suffered from mental illness, or had a history of substance abuse. Cluster 4 had the youngest people and the highest proportion of deaths by jumping from height, few were married, and nearly one-half had bipolar disorder or schizophrenia. Cluster 5 had all unmarried people with no prior suicide attempts, and were the least likely to have an identified mental illness and most likely to leave a suicide note. Conclusions: People who die from suicide assort into different patterns of demographic, clinical, and death-specific characteristics. Identifying and studying subgroups of suicides may advance our understanding of the heterogeneous nature of suicide and help to inform development of more targeted suicide prevention strategies.

    As support times for left ventricular assist devices (LVADs) become longer, several complications requiring device exchange may occur. To our knowledge, this is the first Canadian report regarding implantable LVAD exchange. We retrospectively reviewed the cases of consecutive, unique patients implanted with an LVAD between June 2006 and October 2015 at Toronto General Hospital. In total, 122 patients were impanted with an LVAD during the study period. Eight patients required LVAD exchange, and 1 patient had 2 replacements (9 of 122, 7.3%). There were 7 HeartMate II (HMII), 1 HVAD and 1 DuraHeart pumps exchanged. Two of these exchanges occurred early at the time of initial implant, whereas 7 occurred late (range 8-623 d). Six exchanges were made owing to pump thrombosis. Of the 3 exchanges made for other causes, 1 HMII exchange was owing to a driveline fracture, 1 DuraHeart patient had early inflow obstruction requiring exchange to HMII at the initial implant, and the third had a suspected inflow obstruction with no evidence of thrombosis at the time of the procedure. The mean support time before exchange was 225 days, and time from exchange to transplant, death or ongoing support was 245 days. Three patients were successfully bridged to transplant, and at the time of data collection 2 were supported awaiting transplant. Three patients died after a mean duration of 394.3 days (range 78-673 d) of support postreplacement. Four cases were successfully performed using a subcostal approach. Pump thrombosis is the most common cause for LVAD exchange, which can be performed with acceptable morbidity and mortality. The subcostal approach may be the preferred procedure for an HMII exchange when indicated.

  9. Mismatched racial identities, colourism, and health in Toronto and Vancouver.

    Using original telephone survey data collected from adult residents of Toronto (n = 685) and Vancouver (n = 814) in 2009, I investigate associations between mental and physical health and variously conceived racial identities. An 'expressed racial identity' is a self-identification with a racial grouping that a person will readily express to others when asked to fit into official racial classifications presented by Census forms, survey researchers, insurance forms, and the like. Distinguishing between Asian, Black, South Asian, and White expressed racial identities, I find that survey respondents expressing Black identity are the most likely to report high blood pressure or hypertension, a risk that is slightly attenuated by socioeconomic status, and that respondents expressing Asian identity are the most likely to report poorer self-rated mental health and self-rated overall health, risks that are not explained by socioeconomic status. I also find that darker-skinned Black respondents are more likely than lighter-skinned Black respondents to report poor health outcomes, indicating that colourism, processes of discrimination which privilege lighter-skinned people of colour over their darker-skinned counterparts, exists and has implications for well-being in Canada as it does in the United States. Finally, 'reflected racial identity' refers to the racial identity that a person believes that others tend to perceive him or her to be. I find that expressed and reflected racial identities differ from one another for large proportions of self-expressed Black and South Asian respondents and relatively few self-expressed White and Asian respondents. I also find that mismatched racial identities correspond with relatively high risks of various poor health outcomes, especially for respondents who consider themselves White but believe that others tend to think they are something else. I conclude by presenting a framework for conceptualizing multifaceted suites of racial

    Monitoring of small magnitude ('micro') earthquakes in a dense local network is one of the techniques used to delineate currently active faults and seismic sources. The conventional wisdom is that smaller, but more frequent, seismic events normally occur on active fault planes and a log linear empirical relation between frequency and magnitude can be used to estimate the magnitude and recurrence (frequency) of the larger events. A program of site-specific seismic monitoring has been supported by the AECB since 1991, to investigate the feasibility of microearthquake detection in suburban areas of east Toronto in order to assess the rate activity of local events in the vicinity of the nuclear power plants at Pickering and Darlington. For deployment of the seismic stations at the most favorable locations an extensive background noise survey was carried out. This survey involved measuring and comparing the amplitude response of the ambient vibration caused by natural phenomena (e.g. wind blow, water flow, wave action) or human activities such as farming, mining and industrial work at 25 test sites. Subsequently, a five-station seismic network, with a 30 km aperture, was selected between the Pickering and Darlington nuclear power plants on Lake Ontario, to the south, and Lake Scugog to the north. The detection threshold obtained for two of the stations allows recording of local events M L =0-2, a magnitude range which is usually not detected by regional seismic networks. An analysis of several thousand triggered signals resulted in the identification of about 120 local events, which can not be assigned to any source other than the natural release of crustal stresses. The recurrence frequency of these microearthquakes shows a linear relationship which matches that of larger events in the last two centuries in this region. The preliminary results indicate that the stress is currently accumulating and is being released within clusters of small earthquakes

    For two weeks in August, 1975 more than 140 mathematicians and other scientists gathered at the Universite de Sherbrooke. The occasion was the 15th Biennial Seminar of the Canadian Mathematical Congress, entitled Mathematics and the Life Sciences. Participants in this inter­ disciplinary gathering included researchers and graduate students in mathematics, seven different areas of biological science, physics, chemistry and medical science. Geographically, those present came from the United States and the United Kingdom as well as from academic departments and government agencies scattered across Canada. In choosing this particular interdisciplinary topic the programme committee had two chief objectives. These were to promote Canadian research in mathematical problems of the life sciences, and to encourage co-operation and exchanges between mathematical scientists" biologists and medical re­ searchers. To accomplish these objective the committee assembled a stim­ ulating programme of lectures and talks. Six ...

    The University of Toronto Atmospheric Observatory and Environment Canada's Centre for Atmospheric Research Experiments each has over a decade of ground-based Fourier transform infrared (FTIR) spectroscopy measurements in southern Ontario. We present the Toronto area FTIR time series from 2002 to 2013 of two tropospheric trace gases—ozone and carbon monoxide—along with surface in situ measurements taken by government monitoring programs. We interpret their variability with the GEOS-Chem chemical transport model and determine the atmospheric conditions that cause pollution events in the time series. Our analysis includes a regionally tagged O3 model of the 2004-2007 time period, which quantifies the geographical contributions to Toronto area O3. The important emission types for 15 pollution events are then determined with a high-resolution adjoint model. Toronto O3, during pollution events, is most sensitive to southern Ontario and U.S. fossil fuel NOx emissions and natural isoprene emissions. The sources of Toronto pollution events are found to be highly variable, and this is demonstrated in four case studies representing local, short-, middle-, and long-range transport scenarios. This suggests that continental-scale emission reductions could improve air quality in the Toronto region. We also find that abnormally high temperatures and high-pressure systems are common to all pollution events studied, suggesting that climate change may impact Toronto O3. Finally, we quantitatively compare the sensitivity of the surface and column measurements to anthropogenic NOx emissions and show that they are remarkably similar. This work thus demonstrates the usefulness of FTIR measurements in an urban area to assess air quality.

    Global reduction of chemical deposition into the environment is necessary. In protected horticulture, different strategies with biodegradable products are used to control pathogens. This review presents the available tools, especially for the management of protected horticultural species, including vegetables and ornamental plants. An analysis of the potential for degradable products that control pathogens and also encourage other productive factors, such as oxygen in the root system, is presented. Biosecurity in fertigation management of protected horticulture is conducted by using peroxyacetic acid mixtures that serve three basic principles: first, the manufacture of these products does not involve polluting processes; second, they have the same function as other chemicals, and third, after use and management there is no toxic residue left in the environment. The sustainability of protected horticulture depends on the development and introduction of technologies for implementation in the field.

    Xiong, Jin-Song; Ding, Jing; Li, Yi

    2015-01-01

    Plant breeding, one of the oldest agricultural activities, parallels human civilization. Many crops have been domesticated to satisfy human's food and aesthetical needs, including numerous specialty horticultural crops such as fruits, vegetables, ornamental flowers, shrubs, and trees. Crop varieties originated through selection during early human civilization. Other technologies, such as various forms of hybridization, mutation, and transgenics, have also been invented and applied to crop breeding over the past centuries. The progress made in these breeding technologies, especially the modern biotechnology-based breeding technologies, has had a great impact on crop breeding as well as on our lives. Here, we first review the developmental process and applications of these technologies in horticultural crop breeding. Then, we mainly describe the principles of the latest genome-editing technologies and discuss their potential applications in the genetic improvement of horticultural crops. The advantages and challenges of genome-editing technologies in horticultural crop breeding are also discussed. PMID:26504570

    Scientists interested in understanding how Congress develops science policy would find it useful to read a recent report by the Carnegie Commission on Science, Technology, and Government. “Science, Technology and Congress: Analysis and Advice from the Congressional Support Agencies” contains revealing insights about the often hard-pressed system that Congress uses to analyze science and technology issues.“Congress is on the front line of many battles over the directions of science and technology,” says the 70-page report. “The quality of congressional decisions on these issues often depends on the quality and usefulness of information and analysis made available to Congress.” The report describes the overwhelming amount of information received by members of Congress, few of whom have “substantial training or experience” in science and technology. Making this information understandable and useful is the role of the Office of Technology Assessment, the Congressional Research Service, the General Accounting Office, and the Congressional Budget Office.

  9. The False Panacea of City Charters? A Political Perspective on the Case of Toronto

    Directory of Open Access Journals (Sweden)

    Andrew Sancton

    2016-01-01

    Full Text Available Toronto is unlike any other city, as its local boosters will not hesitate to point out. That was the basis, after all, of the “charter movement” that demanded special rights for a mega-city that the movement’s backers insisted was so vital that it even warranted a status similar to that of an entire province. Their efforts culminated in the province’s passage in 2006 of the City of Toronto Act, which appeared on its face to grant the metropolis the power it believed it required and merited. In reality, the Ontario government may have actually set Toronto back, leaving it more at the mercy of provincial power than other smaller municipalities. The few additional taxation powers that were granted by the ostensible Toronto “charter” — the City of Toronto Act — are, in reality, still overseen by the province, which retains the right to limit those revenue tools if it considers it “desirable in the provincial interest to do so.” But while Toronto may have been given just a small number of revenue tools, which it has used only sparingly, and the use of those tools is ultimately decided by Queen’s Park, their very existence has given the province licence to sidestep the city’s calls for more funding. The provincial Liberals have, in the past, insisted that Toronto make use of its own taxes before it demands more provincial funds. Meanwhile, the City of Toronto Act did nothing to curtail the power of the Ontario Municipal Board (OMB. Because municipal zoning decisions made in Toronto can be appealed to the OMB, which can substitute its own idea of “good planning” for elected local government, the City of Toronto is ultimately left with limited control over its planning decisions. In sum, virtually none of the desires that Toronto expected would be served by a city charter have been fulfilled. Quite the opposite, it would appear that the dreams once imagined by charter-city proponents have been snuffed out, and there is no

    The founding of Britain's first horticultural college in 1889 advanced a scientific and coeducational response to three troubling national concerns: a major agricultural depression; the economic distress of single, unemployed women; and imperatives to develop the colonies. Buoyed by the technical instruction and women's movements, the Horticultural College and Produce Company, Limited, at Swanley, Kent, crystallized a transformation in the horticultural profession in which new science-based, formalized study threatened an earlier emphasis on practical apprenticeship training, with the effect of opening male-dominated trades to women practitioners. By 1903, the college closed its doors to male students, and new pathways were forged for women students interested in pursuing further scientific study. Resistance to the Horticultural College's model of science-based women's horticultural education positioned science and women as contested subjects throughout this period of horticulture's expansion in the academy.

    Increasing concern with the potential earthquake hazard in southern Ontario has focused attention on neotectonic structures affecting bedrock. Within the boundaries of the metropolitan Toronto area (632 km 2 ), about 2500 fracture orientations have been measured in more than 70 bedrock outcrops. An east-northeast systematic fracture set constitute the most commonly-oriented fundamental fracture system in the study area. The east-northeast systematic fracture set may be the product of the current compressive stress field combined with regional uplift, but this should be confirmed by further field investigation. Anomalous fracture patterns were identified at the periphery of Metropolitan Toronto, specifically along the West Humber and Rouge rivers. Four post-glacial pop-ups were identified within Metro Toronto. Careful mapping and description of these pop-ups show a possible relationship with the contemporary principal stresses in the area and the local fracture pattern. (author). 41 refs., 8 figs

    This article decribes the nutrient composition of four strawberry genotypes cultivated at the Sher-e-Bangla Agriculture University horticulture farm in Dhaka (Bangladesh). AOAC and standard validated methods were employed to analyse the nutrient composition. Protein, fat and ash contents were found to be vary significantly (LSD<0.05), while the variation in moisture (LSD<1.33), dietary fibre (LSD<0.15) and total sugar (LSD<0.09) were found to be insignificant among the genotypes. Vitamin C content ranged from 26.46 mg to 37.77 mg per 100g edible strawberries (LSD<0.060). Amount of carotenoids were found to be very low being in a range of 0.99-3.30 μg per 100g edible fruit. Analysis of mineral revealed that strawberry genotypes contained a wide array of minerals including Ca, Mg, Na, K, P, Mn, Zn, Cu and Fe; most of which varied significantly (LSD<0.05) among the genotypes. Strawberries could be a potential dietary supplement for vitamin C along with minerals, particularly for the children who do not like local fruits, but love to eat the colourful strawberries.

    2009-01-01

    This paper presents the design of a new wireless sensor node (GAIA Soil-Mote) for precision horticulture applications which permits the use of precision agricultural instruments based on the SDI-12 standard. Wireless communication is achieved with a transceiver compliant with the IEEE 802.15.4 standard. The GAIA Soil-Mote software implementation is based on TinyOS. A two-phase methodology was devised to validate the design of this sensor node. The first phase consisted of laboratory validation of the proposed hardware and software solution, including a study on power consumption and autonomy. The second phase consisted of implementing a monitoring application in a real broccoli (Brassica oleracea L. var Marathon) crop in Campo de Cartagena in south-east Spain. In this way the sensor node was validated in real operating conditions. This type of application was chosen because there is a large potential market for it in the farming sector, especially for the development of precision agriculture applications.

  15. Occupational health and safety of workers in agriculture and horticulture.

    2000-01-01

    Working in agriculture and horticulture gives considerable job satisfaction. The tasks are often interesting; you can see the result of your own work, watch your crop grow and mature; you have an affinity with nature and can follow the changes in the seasons. However, today it is a dangerous work environment fraught with occupational injuries and diseases due to hazardous situations and to physiological, physical, biological, chemical, psychological, and sociological factors. The ongoing rapid development may, on the other hand, bring about many changes during the next decades with more farmers and growers switching to organic production. Moreover, increased awareness of animal welfare also may lead to improved working conditions. Large-scale operations with fewer family-operated agricultural businesses might mean fewer injuries among children and older farmers. A consequence of large-scale operations may also be better regulation of working conditions. The greater use of automation technology eliminates many harmful working postures and movements when milking cows and carrying out other tasks. Information technology offers people the opportunity to gain more knowledge about their work. Labeling food produced in a worker-friendly work environment may give the consumers a chance to be involved in the process.

    Availability of postharvest technology is becoming abundant, but only a few technologies are applicable and useful to a wider community purposes. Based on this problem it requires a significant readiness level of transfer technology approach. This system is reliable to access readiness a technology with level, from 1-9 and to minimize time of transfer technology in every level, time required technology from the selection process can be minimum. Problem was solved by using Relief method to determine ranking by weighting feasible criteria on postharvest technology in each level and PERT (Program Evaluation Review Technique) to schedule. The results from ranking process of post-harvest technology in the field of horticulture is able to pass level 7. That, technology can be developed to increase into pilot scale and minimize time required for technological readiness on PERT with optimistic time of 7,9 years. Readiness level 9 shows that technology has been tested on the actual conditions also tied with estimated production price compared to competitors. This system can be used to determine readiness of technology innovation that is derived from agricultural raw materials and passes certain stages.

  17. The Multifunctional Role of Chitosan in Horticultural Crops; A Review

    Directory of Open Access Journals (Sweden)

    2018-04-01

    Full Text Available Chitosan is a naturally occurring compound and is commercially produced from seafood shells. It has been utilized in the induction of the defense system in both pre and post-harvest fruits and vegetables against fungi, bacteria, viruses, and other abiotic stresses. In addition to that, chitosan effectively improves the physiological properties of plants and also enhances the shelf life of post-harvest produces. Moreover, chitosan treatment regulates several genes in plants, particularly the activation of plant defense signaling pathways. That includes the elicitation of phytoalexins and pathogenesis-related (PR protein. Besides that, chitosan has been employed in soil as a plant nutrient and has shown great efficacy in combination with other industrial fertilizers without affecting the soil’s beneficial microbes. Furthermore, it is helpful in reducing the fertilizer losses due to its coating ability, which is important in keeping the environmental pollution under check. Based on exhibiting such excellent properties, there is a striking interest in using chitosan biopolymers in agriculture systems. Therefore, our current review has been centered upon the multiple roles of chitosan in horticultural crops that could be useful in future crop improvement programs.

  19. Conflict and compliance: Christianity and the occult in horticultural exporting.

    Science.gov (United States)

    Dolan, C S

    1999-03-01

    The introduction of export horticulture in Meru District, Kenya, brought about disadvantageous effects on female farmers. Their workload increased while their earnings did not. Women reacted by turning to Christianity for support, and resorted to traditional witchcraft to regain control. In this article, Christianity and witchcraft are presented as ways of expressing discontent with the prevailing social norms, and as means to reclaim autonomy and security within their households. Since Kenyan women are entailed to meet the standards of being a good Christian wife, in which women are submissive to their husbands, the church became a means of escaping the confinements of their marriage. In Meru, Christian conversion offers a means of coping with life and an opportunity to interact with other women who share the same experience. Another strategy adopted by women is witchcraft, a traditional relic wherein women give "potions" to their husbands to induce psychosis and eventually death, which would then leave control of the household to the woman. In conclusion, the case presented here demonstrates how failure to recognize cultural dynamics leads to gender inequity and worsens women's well being, as well as men's security.

    2014-10-01

    To provide a review on the benefits associated with the use of sensory gardens and horticultural activities in dementia care. Maintaining quality of life is important in dementia care. Sensory gardens and horticultural activities are increasingly used in dementia care, yet their benefits are uncertain. A modified scoping review with descriptive analysis of selected empirical studies. Systematic searches in Amed, CINAHL, MEDLINE, ISI Web of Science, Embase and Scopus were used. Search terms were the free-text concepts 'healing garden', 'horticultural therapy', 'restorative garden' and 'wander garden' which were combined with dementia and Alzheimer. Sixteen studies were included with included participants ranging from eight to 129 participants. Research designs were case studies (n = 2), survey (n = 1), intervention studies with pretest/post-test design (n = 11) and randomised controlled studies (n = 2). Of these 16 studies, eight examined the benefits of sensory gardens, seven examined horticultural therapy or therapeutic horticulture and one examined the use of plants indoors. This study offers a review of the research addressing benefits of sensory gardens, therapeutic horticulture, horticultural therapy and other purposeful use of plants in dementia care. The reported findings are mainly on issues related to behaviour, affect and well-being. The findings are in general mutually supportive, however, with some contradictory findings. In addition, sleep pattern, well-being and functional level seem to improve. These types of nonpharmacological interventions may improve well-being and affect and reduce the occurrence of disruptive behaviour. Additionally, the use of psychotropic drugs, incidents of serious falls, sleep and sleep pattern also seem to improve. To further improve the use of the existing or planned gardens, an educational programme for staff that also includes skill training is recommended. © 2013 John Wiley & Sons Ltd.

    2017-12-01

    The 1st World Congress of Paediatric Cardiology was held in London, United Kingdom, in 1980, organised by Dr Jane Somerville and Prof. Fergus Macartney. The idea was that of Jane Somerville, who worked with enormous energy and enthusiasm to bring together paediatric cardiologists and surgeons from around the world. The 2nd World Congress of Paediatric Cardiology took place in New York in 1985, organised by Bill Rashkind, Mary Ellen Engle, and Eugene Doyle. The 3rd World Congress of Paediatric Cardiology was held in Bangkok, Thailand, in 1989, organised by Chompol Vongraprateep. Although cardiac surgeons were heavily involved in these early meetings, a separate World Congress of Paediatric Cardiac Surgery was held in Bergamo, Italy, in 1988, organised by Lucio Parenzan. Thereafter, it was recognised that surgeons and cardiologists working on the same problems and driven by a desire to help children would really rather meet together. A momentous decision was taken to initiate a Joint World Congress of Paediatric Cardiology and Cardiac Surgery. A steering committee was established with membership comprising the main organisers of the four separate previous Congresses and additional members were recruited in an effort to achieve numerical equality of cardiologists and surgeons and a broad geographical representation. The historic 1st "World Congress of Paediatric Cardiology and Cardiac Surgery" took place in Paris in June, 1993, organised by Jean Kachaner. The next was to be held in Japan, but the catastrophic Kobe earthquake in 1995 forced relocation to Hawaii in 1997. Then followed Toronto, Canada, 2001, organised by Bill Williams and Lee Benson; Buenos Aires, Argentina, 2005, organised by Horatio Capelli and Guillermo Kreutzer; Cairns, Australia, 2009, organised by Jim Wilkinson; Cape Town, South Africa, 2013, organised by Christopher Hugo-Hamman; and Barcelona, Spain, 2017, organised by Sertac Cicek.

  11. Integral Management of Irrigation Water in Intensive Horticultural Systems of Almería

    Directory of Open Access Journals (Sweden)

    Pedro Garcia-Caparros

    2017-12-01

    Full Text Available The development of intensive horticulture in Almería, with a huge increase in greenhouse surface area, is related to three essential factors: climatic characteristics, groundwater use and mulching sandy soil. The purpose of the present paper is to draw a picture of the integral management of water irrigation in the intensive horticultural systems in the region, by identifying the most significant water resource contributions and alternative water resources. Results indicate that the use of groundwater for the irrigation of horticultural crops in the greenhouses presents a high degree of overexploitation of the aquifers, but due to the continuous search for alternative water resources, such as desalinated and reclaimed water, as well as in-depth knowledge of the integral management of water irrigation through automated fertigation and localized irrigation systems, the current status of the water resources could be sustainable. Moreover, being conscious of the pollution generated by agricultural leachates, the horticultural system of Almería is implementing complementary sustainable systems such as recirculation, cascade cropping systems and phytodepuration for the reuse of the leachate. Considering all these factors, it can be concluded that the intensive horticultural system is on the right path towards respecting the environment and being sustainable in terms of water use.

  12. Grafting: a technique to modify ion accumulation in horticultural crops

    Directory of Open Access Journals (Sweden)

    Muhammad Azher Nawaz

    2016-10-01

    Full Text Available Grafting is a centuries-old technique used in plants to obtain economic benefits. Grafting increases nutrient uptake and utilization efficiency in a number of plant species, including fruits, vegetables, and ornamentals. Selected rootstocks of the same species or close relatives are utilized in grafting. Rootstocks absorb more water and ions than self-rooted plants and transport these water and ions to the aboveground scion. Ion uptake is regulated by a complex communication mechanism between the scion and rootstock. Sugars, hormones, and miRNAs function as long-distance signaling molecules and regulate ion uptake and ion homeostasis by affecting the activity of ion transporters. This review summarizes available information on the effect of rootstock on nutrient uptake and utilization and the mechanisms involved. Information on specific nutrient-efficient rootstocks for different crops of commercial importance is also provided. Several other important approaches, such as interstocking (during double grafting, inarching, use of plant-growth-promoting rhizobacteria, use of arbuscular mycorrhizal fungi, use of plant growth substances (e.g., auxin and melatonin, and use of genetically engineered rootstocks and scions (transgrafting, are highlighted; these approaches can be combined with grafting to enhance nutrient uptake and utilization in commercially important plant species. Whether the rootstock and scion affect each other’s soil microbiota and their effect on the nutrient absorption of rootstocks remain largely unknown. Similarly, the physiological and molecular bases of grafting, crease formation, and incompatibility are not fully identified and require investigation. Grafting in horticultural crops can help reveal the basic biology of grafting, the reasons for incompatibility, sensing, and signaling of nutrients, ion uptake and transport, and the mechanism of heavy metal accumulation and restriction in rootstocks.

    2012-02-01

    The aim of Canadian medical school curricula is to provide educational experiences that satisfy the specific objectives set out by the Medical Council of Canada. However, for specialties such as otolaryngology, there is considerable variability in student exposure to didactic and clinical teaching across Canadian medical schools, making it unclear whether students receive sufficient teaching of core otolaryngology content and clinical skills. The goal of this review was to assess the exposure to otolaryngology instruction in the undergraduate medical curriculum at the University of Toronto. Otolaryngology objectives were derived from objectives created by the Medical Council of Canada and the University of Toronto. The University of Toronto's recently developed Curriculum Mapping System (CMap) was used to perform a keyword search of otolaryngology objectives to establish when and to what extent essential topics were being taught. All (10 of 10) major topics and skills identified were covered in the undergraduate medical curriculum. Although no major gaps were identified, an uneven distribution of teaching time exists. The majority (> 90%) of otolaryngology education occurs during year 1 of clerkship. The amount of preclerkship education was extremely limited. Essential otolaryngology topics and skills are taught within the University of Toronto curriculum. The CMap was an effective tool to assess the otolaryngology curriculum and was able to identify gaps in otolaryngology education during the preclerkship years of medical school. As a result, modifications to the undergraduate curriculum have been implemented to provide additional teaching during the preclerkship years.

  1. Technical efficiency under alternative environmental regulatory regimes: The case of Dutch horticulture

    International Nuclear Information System (INIS)

    Van der Vlist, Arno J.; Withagen, Cees; Folmer, Henk

    2007-01-01

    We consider the performance of small and medium sized enterprises in Dutch horticulture under different environmental policy regimes across time. We address the question whether technical performance differs under these alternative regulatory regimes to test Porter's hypothesis that stricter environmental regulation reduces technical inefficiency. For this purpose, we use a stochastic production frontier framework allowing for inclusion of policy variables to measure the effect of alternative environmental policy regimes on firms' performance. The main result is that stricter environmental policy regimes have indeed reduced technical inefficiencies in Dutch horticulture. The estimation results indicate amongst others that the 1997 agreement on energy, nutrient and pesticides use enhances technical efficiency. Firms under the strict environmental policy regime are found to be more technically efficient than those under a lax regime, thereby supporting the claims by Porter and Van der Linde (Porter, M., Van der Linde, C., 1995. Green and Competitive: Ending the stalemate. Harvard Business Review 73, pp. 120-137) concerning Dutch horticulture. (author)

    Commercialization of horticulture farming, expansion of farms, and the practice of monoculture favor the proliferation of pests, which in turn increases the need for pesticides. Increased exposure to pesticides is associated with inadequate knowledge on the hazardous nature of pesticides, poor hygiene practices, lack of availability of washing facilities, and insufficient adherence to precautionary instructions on pesticide labels. Mitigating the risks posed by pesticides is considered a less compelling interest than alleviating poverty. Women working in horticulture in Tanzania usually have low levels of education and income and lack decision-making power even on matters relating to their own health. This contributes to pesticide exposure and other health challenges. Because of multiple factors, some of which act as study confounders, few studies on exposure to pesticides and health effects have been conducted among women. This review identified factors that contribute to the increased health effects among women working in the horticultural industry and how these effects relate to pesticide exposure.

    Therapists can use horticultural therapy as an adjuvant therapy in a non threatening context, with the intent of bringing about positive effects in physical health, mental health, and social interaction. Very few experimental studies exist that test its clinical effectiveness. To determine whether the addition of horticultural therapy to a pain-management program improved physical function, mental health, and ability to cope with pain. The research team designed a prospective, nonrandomized, controlled cohort study, enrolling all patients consecutively referred to the Zurzach Interdisciplinary Pain Program (ZISP) who met the studys criteria. The team divided them into two cohorts based on when medical professionals referred them: before (control group) or after (intervention group) introduction of a horticultural therapy program. The setting was the rehabilitation clinic (RehaClinic) in Bad Zurzach, Switzerland. Seventy-nine patients with chronic musculoskeletal pain (fibromyalgia or chronic, nonspecific back pain) participated in the study. The research team compared a 4-week, inpatient, interdisciplinary pain-management program with horticultural therapy (intervention, n = 37) with a pain-management program without horticultural therapy (control, n = 42). The horticultural therapy program consisted of seven sessions of group therapy, each of 1-hour duration. The research team assessed the outcome using the Medical Outcome Study Short Form-36 (SF-36), the West Haven-Yale Multidimensional Pain Inventory (MPI), the Hospital Anxiety and Depression Scale (HADS), the Coping Strategies Questionnaire (CSQ ), and two functional performance tests. The team tested participants on entry to and discharge from the 4-week pain-management program. Between-group differences in sociodemographic and outcome variables were not significant on participants entry to the pain-management program. On discharge, the research team measured small to moderate outcome effects (effect size [ES

    Full Text Available Iodine is an essential microelement for humans and iodine deficiency disorder (IDD is one of the most widespread nutrient-deficiency diseases in the world. Iodine biofortification of plants provides an attractive opportunity to increase iodine intake in humans and to prevent and control IDD. This study was conducted to investigate the iodine uptake and accumulation in edible portion of two fruit trees: plum and nectarine, and two horticultural crops: tomato and potato. Two type of iodine treatments (soil and foliar spray application, and, for fresh market tomato, two production systems (open field and greenhouse hydroponic culture were tested. The distribution of iodine in potato stem and leaves, and in plum tree fruits, leaves, and branches was investigated. Iodine content of potato tubers after postharvest storage and processing (cooking, and iodine content of nectarine fruits after postharvest storage and processing (peeling were also determined. Differences in iodine accumulation were observed among the four crops, between applications, and between production systems. In open field, the maximum iodine content ranged from 9.5 and 14.3 μg 100 g−1 for plum and nectarine fruit, to 89.4 and 144.0 μg 100 g−1 for potato tuber and tomato fruit, respectively. These results showed that nectarine and plum tree accumulated significantly lower amounts of iodine in their edible tissues, in comparison with potato and tomato. The experiments also indicated hydroponic culture as the most efficient system for iodine uptake in tomato, since its fresh fruits accumulated up to 2423 μg 100 g−1 of iodine. Iodine was stored mainly in the leaves, in all species investigated. Only a small portion of iodine was moved to plum tree branches and fruits, and to potato stems and tubers. No differences in iodine content after fruit peeling was observed. A significant increase in iodine content of potato was observed after baking, whereas a significant decrease was

    Söderback, Ingrid; Söderström, Marianne; Schälander, Elisabeth

    2004-01-01

    Objectives were to review the literature on horticultural therapy and describe the Danderyd Hospital Horticultural Therapy Garden and its associated horticultural therapy programme. The literature review is based on the search words 'gardening', 'healing garden' and 'horticultural therapy'. The description is based on the second author's personal knowledge and popular-scientific articles initiated by her. The material has been integrated with acknowledged occupational therapy literature. The setting was the Danderyd Hospital Rehabilitation Clinic, Sweden, Horticultural Therapy Garden. Forty-six patients with brain damage participated in group horticultural therapy. Horticulture therapy included the following forms: imagining nature, viewing nature, visiting a hospital healing garden and, most important, actual gardening. It was expected to influence healing, alleviate stress, increase well-being and promote participation in social life and re-employment for people with mental or physical illness. The Horticultural Therapy Garden was described regarding the design of the outdoor environment, adaptations of garden tools, cultivation methods and plant material. This therapy programme for mediating mental healing, recreation, social interaction, sensory stimulation, cognitive re-organization and training of sensory motor function is outlined and pre-vocational skills and the teaching of ergonomical body positions are assessed. This study gives a broad historic survey and a systematic description of horticultural therapy with emphasis on its use in rehabilitation following brain damage. Horticulture therapy mediates emotional, cognitive and/or sensory motor functional improvement, increased social participation, health, well-being and life satisfaction. However, the effectiveness, especially of the interacting and acting forms, needs investigation.

    2010-01-01

    Full Text Available The congress industry, as a part of business tourism sector, is globally recognized for its valuable economic contribution to tourism destinations. Regardless economic benefits, there are as well as numerous social, cultural and environmental benefits that congress industry brings to destinations. This is the reason why the congress industry is becoming one of the fastest growing sectors of tourism industry. At the same time, the congress destinations worldwide are competing in bidding international congresses. According to the Strategy of Tourism Development of the Republic of Serbia (2005, congress tourism is recognized as a quick win product that could contribute in a short period of 3 to 5 years to tourism development and image of Serbia. The cities of Belgrade, Novi Sad and Niš are identified as the congress destinations capable for hosting international congresses. Novi Sad, as administrative, economic, cultural, scientific and educational centre of the region of Vojvodina (northern part of Serbia and known as 'town of fairs'(it has long tradition in organizing fairs - since 1923 has strong potential for smaller international congresses. In order to improve quality of 'congress' tourist product, provide stability of congress destination and congress centers, it is necessary to understand meeting planners' and congress attendees' levels of satisfaction and reaction to their experience in destination. In Serbia there is no research regarding mentioned items. The aim of this paper is to examine and analyze the perspective of the congress attendees, as they are final consumers of congress tourist product and their experience and behavioural intentions regarding Novi Sad is thus essential to destination marketing and management organizations, congress centre, hotel managers and meeting planners. .

    Participation in horticulture and arts may improve wellbeing in those with mental and physical illness. To conduct an in-depth exploration of the views and experience of participants of a primary-care-based horticultural and participatory arts rehabilitation project (Sydenham Garden). Qualitative interview study of a primary-care-based horticultural and participatory arts rehabilitation project in South London. Semi-structured interviews were conducted with 16 participants (referred to as 'coworkers') of Sydenham Garden. Seven were female. Participants were aged between 38 and 91 years and had a range of severe mental and physical health problems; most had depression. The interviews were analysed using constant comparison and thematic analysis. Data were overwhelmingly positive concerning participation. Coworkers considered participation in the project to promote wellbeing by providing purposeful and enjoyable activity and interest, improving mood and self-perceptions, and providing an escape from life's pressures. Being outdoors was considered therapeutic. The most-valued aspect of participation was the social contact derived as a result of it. Many of the coworkers who were interviewed developed transferable skills, including nationally recognised qualifications, which they valued highly. Delivery of horticultural therapy and participatory arts is a feasible model for improving wellbeing in patients in primary care who have serious illness. Longer-term studies are needed to address what happens to people after leaving such projects.

    In Sub-Saharan Africa, horticulture provides livelihood opportunities for millions of people, especially in urban and peri-urban areas. Although the vegetable agroecosystems are often characterized by intensive pesticide use, risks resulting therefrom are largely unknown under tropical horticultural conditions. The objective of this study therefore was to study the fate of pesticides in two representative horticultural soils (Acrisol and Arenosol) and plants (Solanum macrocarpon L.) after field application and thus to gain first insight on environmental persistence and dispersion of typical insecticides used in vegetable horticulture in Benin, West Africa. On plant surfaces, dissipation was rapid with half lives ranging from 2 to 87 h (alpha-endosulfan < beta-endosulfan < deltamethrin). Soil dissipation was considerably slower than dissipation from plant surfaces with half-lives ranging from 3 (diazinon) to 74 d (total endosulfan), but persistence of pesticides in soil was still reduced compared to temperate climates. Nevertheless, for deltamethrin and endosulfan, a tendency for mid-term accumulation in soil upon repeated applications was observed. The soil and plant surface concentrations of the metabolite endosulfan sulfate increased during the entire trial period, indicating that this compound is a potential long-term pollutant even in tropical environments.

    Horticultural crops are an important part of agriculture for food as well as nutritional security. However, several pests and diseases along with adverse abiotic environmental factors pose a severe threat to these crops by affecting their quality and productivity. This warrants the effective and accelerated breeding programs by utilizing innovative biotechnological tools that can tackle aforementioned issues. The recent technique of genome editing by Clustered Regularly Interspaced Short Palindromic Repeats/CRISPR associated 9 (CRISPR/Cas9) has greatly advanced the breeding for crop improvement due to its simplicity and high efficiency over other nucleases such as Zinc Finger Nucleases and Transcription Activator Like Effector Nucleases. CRISPR/Cas9 tool contains a non-specific Cas9 nuclease and a single guide RNA that directs Cas9 to the specific genomic location creating double-strand breaks and subsequent repair process creates insertion or deletion mutations. This is currently the widely adopted tool for reverse genetics, and crop improvement in large number of agricultural crops. The use of CRISPR/Cas9 in horticultural crops is limited to few crops due to lack of availability of regeneration protocols and sufficient sequence information in many horticultural crops. In this review, the present status of applicability of CRISPR/Cas9 in horticultural crops was discussed along with the challenges and future potential for possible improvement of these crops for their yield, quality, and resistance to biotic and abiotic stress.

    Scarce information is available about the energy use pattern of horticultural commodities in general and more specifically for peri-urban horticulture. Peri-urban horticulture in the outskirts of Bogota is an important source of vegetables for Colombia's capital city. Based on detailed follow-ups and periodic field measurements an output-input energy balance was performed with the main objective to study the energy use efficiency of those systems. An uncertainty analysis on the input factors and on the energy equivalents was then applied. Over a measurement period of 18-month, the energy use for coriander, lettuce, radish and spinach was investigated, respectively 12.1, 18.8, 6.6 and 10.7 GJ ha{sup -1} were consumed in these cropping systems. Negative balances were observed for all species exception made for spinach where an output:input ratio of 1.16 was found. The two-way uncertainty analysis showed the highest uncertainty for N-based fertilization while no significant effect was observed for seeds in direct sowing crops. Sustainability of peri-urban horticulture around Bogota is compromised not only because of the city expansion but also due to its inefficient energy use. Technical improvements are required to ensure the environmental subsistence of this important sector for the metropolitan area of the city. (author)

  15. Jodï horticultural belief, knowledge and practice: incipient or integral cultivation?

    Directory of Open Access Journals (Sweden)

    Stanford Zent

    Full Text Available This paper describes the Jodï horticultural system, including belief, knowledge and practice aspects. The horticultural practices of the Jodï were previously characterized as 'incipient cultivation' but such practices were poorly described and documented. The antiquity of cultivation among this group is suggested by the prominence and significance of horticultural products and techniques in myth and ritual. Our field observations uncovered a fairly sophisticated system of plant management in swiddens, house gardens, trail gardens and natural forest gaps. An inventory of 67 cultivated plant species was documented, of which 36 are utilized for food, 20 for magical or medicinal purposes, and 11 for technology. The Jodï prolong the productive phase of their gardens for five years or more through successive planting-harvesting-replanting operations. Jodï swiddens display an elaborate polycultivated appearance and they possess at least five principal crops: plantain/banana, maize, yams, sweet potato, and sweet manioc. Another distinctive feature is the extensive use of natural gaps in the forest canopy as cultivation zones. The results of this study suggest that while Jodï horticultural practice is well integrated with a nomadic, foraging-dependent lifestyle, nevertheless this system does not deserve to be labeled as 'incipient' and instead is more integral than was recognized previously.

    2012-01-01

    The current status of trade in horticultural products irradiated for phytosanitary purposes is examined, including trends, strengths and weaknesses. A strategy is proposed to take advantage of the best future opportunities for increasing trade in irradiated horticultural products by identifying best possibilities for expanding both the number and volume of commodities for irradiation and then applying appropriate business criteria in a general analysis of the commodities, commercial scenarios, and geographic regions where the greatest potential exists for expansion. The results show that fresh fruits such as mango, papaya, citrus, grapes, and vegetables such as tomatoes, onions, asparagus, garlic, and peppers from Asia and the Americas show the greatest potential. Substantial opportunities for additional growth exist, especially as regulatory conditions become more favorable. - Highlights: ► This research examined the trade in horticultural products irradiated for Phytosanitary purposes. ► Paper describes strategies for enhancing trade in irradiated horticultural products. ► Results identify commodities and regions with the greatest potential. ► Additional growth potential exists, especially as regulatory conditions become more favorable.

    Full Text Available Recently, the Korean government has been carrying out projects to construct several large scale horticulture facilities. However, it is difficult for an energy supply to operate stably and economically with only a conventional fossil fuel boiler system. For this reason, several unused energy sources have become attractive and it was found that power plant waste heat has the greatest potential for application in this scenario. In this study, we performed a feasibility assessment of power plant waste heat as an energy source for horticulture facilities. As a result, it was confirmed that there was a sufficient amount of energy potential for the use of waste heat to supply energy to the assumed area. In Dangjin, an horticultural area of 500 ha could be constructed by utilizing 20% of the energy reserves. In Hadong, a horticulture facility can be set up to be 260 ha with 7.4% of the energy reserves. In Youngdong, an assumed area of 65 ha could be built utilizing about 19% of the energy reserves. Furthermore, the payback period was calculated in order to evaluate the economic feasibility compared with a conventional system. The initial investment costs can be recovered by the approximately 83% reduction in the annual operating costs.

    Background Participation in horticulture and arts may improve wellbeing in those with mental and physical illness. Aim To conduct an in-depth exploration of the views and experience of participants of a primary-care-based horticultural and participatory arts rehabilitation project (Sydenham Garden). Design and setting Qualitative interview study of a primary-care-based horticultural and participatory arts rehabilitation project in South London. Method Semi-structured interviews were conducted with 16 participants (referred to as ‘coworkers’) of Sydenham Garden. Seven were female. Participants were aged between 38 and 91 years and had a range of severe mental and physical health problems; most had depression. The interviews were analysed using constant comparison and thematic analysis. Results Data were overwhelmingly positive concerning participation. Coworkers considered participation in the project to promote wellbeing by providing purposeful and enjoyable activity and interest, improving mood and self-perceptions, and providing an escape from life’s pressures. Being outdoors was considered therapeutic. The most-valued aspect of participation was the social contact derived as a result of it. Many of the coworkers who were interviewed developed transferable skills, including nationally recognised qualifications, which they valued highly. Conclusion Delivery of horticultural therapy and participatory arts is a feasible model for improving wellbeing in patients in primary care who have serious illness. Longer-term studies are needed to address what happens to people after leaving such projects. PMID:22520790

    2015-09-01

    This preliminary study examined the effect of horticultural therapy on psychosocial health in older nursing home residents. A combined quantitative and qualitative design was adopted. Convenience sampling was used to recruit 10 older residents from a nursing home in Taichung, Taiwan. Participants joined a 10-week indoor horticultural program once a week, with each session lasting for about 1.5 hours. A single-group design with multiple measurements was adopted for the quantitative component of this study. Interviews held 1-2 days before the intervention (T0) were used to collect baseline data. The two outcome variables of this study, depression and loneliness, were reassessed during the 5th (T1) and 10th (T2) weeks of the intervention. Generalized estimating equations were used to test the mean differences among T0, T1, and T2 measures. After the 10-week program, qualitative data were collected by asking participants to share their program participation experiences. The results of generalized estimating equation showed significant improvements in depression and loneliness. Four categories emerged from the qualitative data content analysis: social connection, anticipation and hope, sense of achievement, and companionship. Given the beneficial effects of the horticulture therapy, the inclusion of horticultural activities in nursing home activity programs is recommended.

    By Congress in 1977 as an independent entity within the Department of Energy, the Energy Information Administration (EIA) is the principal and authoritative source of comprehensive energy data for the Congress, the Federal Government, the States, and the public. During 1992, EIA provided information and analysis in response to many energy-related issues and events, including Hurricane Andrew. In addition, EIA made substantial strides in a number of critical special projects, most notably development of the National Energy Modeling System, preparation of National Petroleum Council studies on petroleum refining and natural gas, and establishment of oxygenate data program mandated by the Clean Air Act Amendments of 1990. EIA also took advantage of new opportunities for international consultations and energy information exchanges. This report to Congress contains energy-related information on the following: petroleum; natural gas; integrated analysis and forecasting; electricity; coal; energy markets and end use, nuclear, statistical standards, and information services. The appendices include: data collection surveys of the Energy Information Administration; Analytic models of the Energy Information Administration; EIA publication -- EIA products available on diskette; and Major laws affecting EIA, 1974-1992.

  10. Workforce challenges and opportunities in the solar photovoltaic industry in Toronto

    Saneinejad, Sheyda

    2011-01-01

    In December 2009, the city of Toronto adopted principles and targets for the city's sustainable energy future. The city plans to install 2 MW of solar photovoltaic panels in its facilities. The aim of this study is to assess the impact of such a project, as well as further expansion of solar photovoltaic energy generation, from the economic development perspective. A literature review, online surveys and interviews with solar industries were carried out and a job estimation model was developed. Results showed that the 2 MW installation would create 53 person years of employment locally while expansion of the technology throughout the city could generate 100,000 local jobs. However this research also pointed out a lack of suitably qualified and experienced personnel Canada-wide. This study demonstrated that the solar photovoltaic industry has the potential to provide significant economic benefits in Toronto but that certification programs must be put in place to address the lack of qualified personnel.

  11. Energy solutions, neo-liberalism, and social diversity in Toronto, Canada.

    Teelucksingh, Cheryl; Poland, Blake

    2011-01-01

    In response to the dominance of green capitalist discourses in Canada's environmental movement, in this paper, we argue that strategies to improve energy policy must also provide mechanisms to address social conflicts and social disparities. Environmental justice is proposed as an alternative to mainstream environmentalism, one that seeks to address systemic social and spatial exclusion encountered by many racialized immigrants in Toronto as a result of neo-liberal and green capitalist municipal policy and that seeks to position marginalized communities as valued contributors to energy solutions. We examine Toronto-based municipal state initiatives aimed at reducing energy use while concurrently stimulating growth (specifically, green economy/green jobs and 'smart growth'). By treating these as instruments of green capitalism, we illustrate the utility of environmental justice applied to energy-related problems and as a means to analyze stakeholders' positions in the context of neo-liberalism and green capitalism, and as opening possibilities for resistance.

    Full Text Available Toronto has the largest absolute number of food insecure households for any metropolitan census area in Canada: of its 2.1 million households, roughly 252 000 households (or 12% experience some level of food insecurity. Community organizations (including social agencies, school programs, and child care centres serve millions of meals per year to the city’s most vulnerable citizens, but often face challenges accessing fresh produce at affordable prices. Therefore in 2015, Toronto Public Health, in collaboration with public- and private-sector partners, launched the FoodReach program to improve the efficiency of food procurement among community organizations by consolidating their purchasing power. Since being launched, FoodReach has been used by more than 50 community organizations to provide many of Toronto’s most marginalised groups with regular access to healthy produce.

    2011-01-01

    Despite extensive literature on the nature and impact of gentrification, there has been little consideration of the effects of gentrification on ethnic neighbourhoods. This study evaluates the negative and positive effects of gentrification on the Portuguese in west central Toronto. Details concerning the settlement patterns of the Portuguese, the characteristics of Portuguese residents and patterns of gentrification in inner-city Toronto were obtained from census data. Evaluations of neighbourhood change and attitudes of the residents towards gentrification were obtained from key informant and focus group interviews. The results suggest considerable ambivalence among the respondents, but most agreed that the long-term viability of Little Portugal as an immigrant reception area with a good supply of low-cost housing is in doubt.

    Androgens are crucial for normal testicular descent. Studies show that some pesticides have estrogenic or antiandrogenic effects, and that female workers exposed to pesticides have increased risk of having a boy with cryptorchidism. The main objective of the present study was to investigate whether pregnant women exposed to pesticides due to their work in horticulture experience excess risk of having sons with cryptorchidism. We conducted a cohort study of pregnant women working in horticulture using four cohorts including one cohort established with data from the departments of occupational medicine in Jutland and Funen and three existing mother-child cohorts (n=1,468). A reference group was established from the entire Danish population of boys born in the period of 1986-2007 (n=783,817). Nationwide Danish health registers provided information on birth outcome, cryptorchidism diagnosis and orchiopexy. The level of occupational exposure to pesticides was assessed by expert judgment blinded towards outcome status. Risk of cryptorchidism among exposed horticulture workers compared to the background population and to unexposed horticulture workers was assessed by Cox regression models. Pesticide exposed women employed in horticulture had a hazard ratio (HR) of having cryptorchid sons of 1.39 (95% CI 0.84; 2.31) and a HR of orchiopexy of 1.34 (0.72; 2.49) compared to the background population. Analysis divided into separate cohorts revealed a significantly increased risk of cryptorchidism in cohort 2: HR 2.58 (1.07;6.20) and increased risk of orchiopexy in cohort 4: HR 2.76 (1.03;7.35), but no significant associations in the other cohorts. Compared to unexposed women working in horticulture, pesticide exposed women had a risk of having sons with cryptorchidism of 1.34 (0.30; 5.96) and of orchiopexy of 1.93 (0.24;15.4). The data are compatible with a slightly increased risk of cryptorchidism in sons of women exposed to pesticides by working in horticulture.

  19. Replacing the nation in the age of migration: negotiating South Asian identities in Toronto

    Directory of Open Access Journals (Sweden)

    Ishan Ashutosh

    2015-08-01

    Full Text Available This essay examines the role of the national in shaping the geo-political divides and connections of the South Asian diaspora in Toronto. South Asian diaspora identities are explored through two contrasting political projects that reveal the ambivalent role of the nation in producing diasporic subjectivities and their shifting borders. First, by discussing the perceptions of South Asians in Toronto, it is contended that national and religious divides are reproduced in the diaspora as a means of national belonging to the society of settlement. Diasporic geo-political divides are not merely transposed from societies of origin to settlement, but rather lie at the intersection of transnational and multicultural politics that encompass societies of origin and settlement. The reproduction of national divides in the South Asian diaspora is situated in the neighbourhoods of immigrant settlement that are positioned as the objects of multicultural efficacy. The second political project reconstitutes the national through cross-national solidarities. Through a discussion of South Asian organizations and political initiatives in Toronto and other cities in North America, this section illuminates diasporic politics predicated on new understandings of history and connection that rejuvenate and politicize multicultural politics. The argument presented finds that national boundaries are re-inscribed in the diaspora at the intersection of the multiple claims of membership. Simultaneously, experiences and interactions in the diaspora provide the grounds for transforming and questioning the limits of national belonging.

  20. Inventorying Toronto's single detached housing stocks to examine the availability of clay brick for urban mining.

    Ergun, Deniz; Gorgolewski, Mark

    2015-11-01

    This study examines the stocks of clay brick in Toronto's single detached housing, to provide parameters for city scale material reuse and recycling. Based on consensus from the literature and statistics on Toronto's single detached housing stocks, city scale reusable and recyclable stocks were estimated to provide an understanding of what volume could be saved from landfill and reintroduced into the urban fabric. On average 2523-4542 m(3) of brick was determined to be available annually for reuse, which would account for 20-36% of the volume of virgin brick consumed in new house construction in 2012. A higher volume, 6187 m(3) of brick, was determined to be available annually for recycling because more of the prevalence of cement-based mortar, which creates challenges for brick reuse in Toronto. The results demonstrated that older housing containing reusable brick were being mostly landfilled and replaced with housing that contained only recyclable brick. Copyright © 2015 Elsevier Ltd.

  1. Potential for occupational and environmental exposure to ten carcinogens in Toronto

    Energy Technology Data Exchange (ETDEWEB)

    Muller, P. [ToxProbe Inc., Toronto, ON (Canada)

    2002-03-01

    A study was conducted in which several contaminants were assessed for their toxicological properties, potencies and occupational and environmental exposures in the city of Toronto. The contaminants included 1,3-butadiene, asbestos, benzene, cadmium, chromium, dioxins, formaldehyde, polycyclic aromatic hydrocarbons (PAHs), tetrachloroethylene, and trichloroethylene. The International Agency for Research on Cancer, the United States Environmental Protection Agency, and Health Canada have classified 9 of the 10 substances as human carcinogens. Tetrachloroethylene was classified as a probable human carcinogen. It was noted that there is no level of exposure for these chemicals that is without some risk. The information on the levels of selected contaminants in the workplace were obtained from existing literature. The sectors with the highest number of potentially exposed workers to these contaminants include the textiles industry, footwear manufacturing, wood products manufacturing, rubber products manufacturing, non-metallic mineral products manufacturing, fabricated metal products manufacturing, construction, land transport, and household services. The report discussed sources of emissions, routes and pathways of exposures and environmental levels, including outdoor air levels water concentrations, soil concentrations, and food concentrations. The report does not estimate the actual risk to Toronto residents due to environmental exposure to these carcinogens because data are insufficient to conduct such an assessment. However, some previous studies have indicated that exposure from ambient and indoor air has the greatest impact on human health. It is recommended that the city of Toronto remain up to date on the regulatory status of these chemicals. refs., tabs., figs., appendices.

    This study aimed to determine the effects of a plant cultivation-based horticultural therapy program for elderly people with mental health problems. Pre- and post-test design with experimental and control groups. Twenty-eight elderly Korean people with mental health problems participated from April to June 2017 at a farm located in Suwon, South Korea. The participants were randomly assigned to either the control (n = 14) or horticultural therapy group (n = 14); the latter participated in once-weekly sessions of a previously designed 10-session horticultural therapy program. The pre-test occurred 1 week before starting the horticultural therapy program. The post-test was completed within 1 week after finishing the final program session. Cortisol levels were measured in saliva samples collected from both groups. The Senior Fitness Test was used to assess physical functional ability in both groups. In the horticultural therapy group, the cortisol levels decreased significantly from before to after the horticultural therapy program, and the post-test scores for six subtests of the Senior Fitness Test improved significantly. No significant improvements were seen in either measure in the control group. This study demonstrates the potential ability of horticultural therapy to improve the stress levels and physical functional abilities of elderly people with mental health problems. In future studies, it would be interesting to verify the long-term effects of this horticultural therapy program and to compare its effects with regard to sex, age, and various mental symptoms.

  17. Application of gas-fired infra-red radiator to thermal disinfection of horticultural substrate

    International Nuclear Information System (INIS)

    Wawer, M.; Osiński, A.

    1998-01-01

    The studies were carried out on heating horticultural substrate (moor peat - bark, 1:1 by volume) with a gas-fired infra-red radiator to destroy the pests and pathogens. Minimum distance between radiator and substrate surface was determined considering assumed time of heating. Dynamics of substrate heating was determined depending on its layer thickness and kind of surface under substrate layer; black rubber, ground steel sheet and aluminium foil were used as the surface. Considerable decreasing of infra-red radiation penetrability through the substrate layer above 7 mm thick was found as well as an significant effect of the radiation reflected from the surface under substrate layer on the intensity of its heating. It was also stated that heating horticultural substrates with the gas-fired infra-red radiator enables to rise the temperature of thin substrate layer up to 70 degree of C within relatively short time [pl

    2008-01-01

    The need for a closed and sustainable water system in greenhouse areas is stimulated by the implementation in the Netherlands of the European Framework Directive. The Dutch national project Kasza: Design of a Closed Water System for the Greenhouse Horticulture will provide information how the water system in a greenhouse horticulture area can be closed. In this paper the conceptual design of two systems to close the water cycle in a greenhouse area is described. The first system with reverse osmosis system can be used in areas where desalination is required in order to be able to use the recycle water for irrigation of all crops. The second system with advanced oxidation using UV and peroxide can be applied in areas with more salt tolerant crops and good (low sodium) water sources for irrigation. Both systems are financially feasible in new greenhouse areas with substantial available recycle water. (c) IWA Publishing 2008.

    2014-01-01

    In Togo, more than six hundred species of horticultural plants were identified belonging to approximately 59% of Dicotyledons (49 families, 145 genera and 315 species) and 37.37% were monocotyledons. Pteridophytes and gymnosperms accounted for less than 6%. The spectrum of morphological types indicated that herbs accounted for 55%, while trees and shrubs were 15%. More than 50% of the species of this flora were exotic. The species distributions were made according to their decorative parts and their place of use. Across the country, 55 plantings were recorded and unevenly distributed in cities. Apart from their ornamental use, these plants were used for feeding, traditional and industrial cosmetics in psychotherapy, horticultural therapy and in traditional and conventional medicine preparation. In this study, 79 species from 39 families are reported as medicinal plants. The Apocynaceae and Fabaceae (6 species), the Euphorbiaceae and Liliaceae (5 species), the Arecaceae and Verbenaceae (4 species) were the best represented families. (author)

    on occupation and cryptorchidism. METHODS: The cohort consisted of >600 000 boys born in Denmark from 1980-2007 with a parent in employment during pregnancy. These boys were followed for cryptorchidism from 1980-2009 comparing risks among sons of horticultural workers and farmers with sons of parents in other...... occupations. Hazard ratios (HR) and 95% confidence intervals (95% CI) were estimated using Cox regression adjusting for parental age, birth years, parity, and geographical region. RESULTS: Sons of maternal farmers were at increased risk of cryptorchidism (157 cases; HR 1.31, 95% CI 1.12-1.53) compared to boys...... of mothers in other occupations (15 511 cases). Paternal occupation as farmer was unrelated to the risk among sons. Maternal occupation as a horticultural worker was associated with a non-significantly increased risk (72 cases; HR 1.20, 95% CI 0.95-1.52). A similar association was found for paternal...

    2010-12-01

    Engaging persons with dementia in meaningful activities supports well-being; however, care staff are challenged to implement age- and ability-appropriate activities in a group setting. We compared a randomly assigned treatment group, who received horticultural therapy-based (HT-based) programming to a comparison group, who engaged in traditional activities (TA) programming, on engagement and affect. Horticultural therapy-based programming was implemented twice weekly at 4 treatment sites for 6 weeks, while regular TA were observed at comparison sites. Results revealed no differences between groups on affective domains. Levels of adaptive behavior differed between the groups, with the treatment group demonstrating higher levels of active, passive, and other engagement and the comparison group demonstrating higher levels of self-engagement. Our results highlight the value of HT-based programs and the importance of simultaneously capturing participants' affective and behavioral responses. Theoretical and practical considerations about the facilitation of and context in which the programming occurs are discussed.

  5. Electricity demand and energy consumption in horticulture and conclusions bearing on energy economy. AEL-Bericht

    Energy Technology Data Exchange (ETDEWEB)

    1980-01-01

    The studies demonstrate that horticultural entreprises, esp. those with a higher electricity consumption, have often not settled for a more favourable electricity tariff. Nor do they use cheaper electricity at slack periods (night current) to the extent possible. Substantial improvement could be obtained above all by fully utilizing the installed capacity through purposeful utilization of machinery and interlocking of major consumers. Measures appropriate to this end are listed allowing a possible economic utilization of electric energy.

  6. Undergraduate Writing Promotes Student’s Understanding of International Sustainable Development in Horticulture

    2011-12-01

    Full Text Available Promotion of undergraduate student thinking and learning in the realm of sustainable production is a new focus for horticulture curricula. In a writing intensive course, Greenhouse Management (Hort 3002W; University of Minnesota, students focus their learning of sustainability by writing peer-reviewed, 3-phase ‘Worldwide Sustainable Horticultural Crop Production Papers’ on past, present, and future prospects for sustainability. The USA is used as an in-class example throughout the semester while each student focuses their writing on a specific country of their choosing. Their papers focus on eight goals for each country across the three Phases: I—their choice of a country, definition of sustainability, identification of historical production practices, current production statistics; II—current production practices and integration of historical/current practices (ranked strategies; III—finalized sustainable development strategy, design of a future sustainable, controlled-environment production facility. The last two goals (Phase III provide plant breeders with potential breeding objectives for country-specific cultivar development within a sustainable production framework. Completed papers are web-published for global availability to enable each country’s researchers and policy makers to access sustainable ideas for future development. In 2009–2010, ‘Worldwide Sustainable Horticultural Crop Production Papers’ were published for 41 countries which were downloaded 3900 times in 19 months through April 2011. This large readership indicates such an assignment can generate interest in either undergraduate writing about developing sustainable horticulture and/or the topic area itself, although the exact purpose of the downloads or the location of the users could not be determined.

  9. Assessing Greenhouse Gas emissions in the Greater Toronto Area using atmospheric observations (Invited)

    Science.gov (United States)

    Vogel, F. R.; Chan, E.; Huang, L.; Levin, I.; Worthy, D.

    2013-12-01

    Urban areas are said to be responsible for approximately 75% of anthropogenic Greenhouse Gases (GHGs) emissions while comprising only two percent of the land area [1]. This limited spatial expansion should facilitate a monitoring of anthropogenic GHGs from atmospheric observations. As major sources of emissions, cities also have a huge potential to drive emissions reductions. To effectively manage emissions, cities must however, first measure and report these publicly [2]. Modelling studies and measurements of CO2 from fossil fuel burning (FFCO2) in densely populated areas does, however, pose several challenges: Besides continuous in-situ observations, i.e. finding an adequate atmospheric transport model, a sufficiently fine-grained FFCO2 emission model and the proper background reference observations to distinguish the large-scale from the local/urban contributions to the observed FFCO2 concentration offsets ( ΔFFCO2) are required. Pilot studies which include the data from two 'sister sites*' in the vicinity of Toronto, Canada helped to derive flux estimates for Non-CO2 GHGs [3] and improve our understanding of urban FFCO2 emissions. Our 13CO2 observations reveal that the contribution of natural gas burning (mostly due to domestic heating) account for 80%×7% of FFCO2 emissions in the Greater Toronto Area (GTA) during winter. Our 14CO2 observations in the GTA, furthermore, show that the local offset of CO2 (ΔCO2) between our two sister sites can be largely attributed to urban FFCO2 emissions. The seasonal cycle of the observed ΔFFCO2 in Toronto, combined with high-resolution atmospheric modeling, helps to independently assess the contribution from different emission sectors (transportation, primary energy and industry, domestic heating) as predicted by a dedicated city-scale emission inventory, which deviates from a UNFCCC-based inventory.

    Exposure models are needed to evaluate the chronic health effects of ambient ultrafine particles (bus routes as well as variables for the number of on-street trees, parks, open space, and the length of bus routes within a 100 m buffer. There was no systematic difference between measured and predicted values when the model was evaluated in an external dataset, although the R(2) value decreased (R(2) = 50%). This model will be used to evaluate the chronic health effects of UFPs using population-based cohorts in the Toronto area. Crown Copyright © 2015. Published by Elsevier Ltd. All rights reserved.

  11. Technological innovations in the horticultural sector in northwestern Mexico: adoption speed and diffusion networks analysis

    Directory of Open Access Journals (Sweden)

    Belem Dolores Avendaño-Ruiz

    2017-09-01

    Full Text Available The article focuses on the identification of innovation adoption and diffusion processes in the export horticultural sector in northwestern Mexico, and the differences identified taking into account the type of producer depending on the production size. The results of the adoption speed index suggests that large producers are distinguished as being early adopters and leaders in innovation adoption in this activity; but as long as there is a technological gap between small and large producers, that is increased even more by economical limita-tions, these will be identified as late adopters for this activity, supported by public programs for its adoption. The study was conducted in four entities of northwestern Mexico, Baja California, Baja California Sur, Sonora and Sinaloa, that in average contribute with 17 % of the national horticultural production. The international market is a strong promotor in innovation adoption, particularly in those related to food safety standards that are adopted by 84 % of the producers. The network analysis highlights the role of union organizations as technological innovation diffusors, e.g. the Confederation of Agricultural Associations of the Sinaloa State, and the Local Agricultural Association of horticulture, Fruits and Legumes of Hermosillo in Sonora.

  12. Export horticulture – empowering female small-scale farmers in Kenya?

    Directory of Open Access Journals (Sweden)

    Velte, Maria

    2014-09-01

    Full Text Available Export horticulture is one of Kenya’s most dynamic sectors, with the Mount Kenya Region playing a crucial role as a result of its professional large- and small-scale production and marketing structures. The sector is consequently referred to as a “success story of African regional development” (Dolan and Sutherland 2002: 1. A qualitative case study was carried out to understand the impacts on gender inequality of the integration of horticultural smallholdings into the fresh fruit and vegetable (FFV supply chain to the European market. It will be outlined how export horticulture affects female small-scale farmers with reference to local distribution channels, the organisation of the farm as a group or an individual player, and the specific organisation of labour on the farm. The focus here is on the traditional division of labour, ownership and mobility patterns, as well as knowledge and income. The study shows that the influence of the integration in the FFV chain on gender inequality is conditioned by both the type of relations to the buyers and the internal and institutional organisation of the smallholding. Surprisingly, in some areas of the primarily male-dominated rural society, an integration in the form of outgrower schemes that resembles Gereffi et al.’s model of a captive value chain, with women farmers exclusively responsible for export production, can enhance gender equality, as women gradually gain more decision-making power and greater independence.

    Herbicides are regularly applied in horticultural production systems and may migrate off-site, potentially posing an ecological risk to surface waterways. However, few studies have investigated the levels and potential ecotoxicological impact of herbicides in horticultural catchments in southern Australia. This study investigated the presence of 10 herbicides at 18 sites during a 5-month period in horticulturally important areas of the Yarra Valley in southeastern Australia. Seven of the 10 herbicides were detected in the streams, in 39 % of spot water samples, in 25 % of surface sediment samples, and in >70 % of the passive sampler systems deployed. Few samples contained residues of ≥2 herbicides. Simazine was the herbicide most frequently detected in water, sediment, and passive sampler samples and had the highest concentrations in water (0.67 μg/L) and sediment (260 μg/kg dry weight). Generally the concentrations of the herbicides detected were several orders of magnitude lower than reported ecotoxicological effect values, including those for aquatic plants and algae, suggesting that concentrations of individual chemicals in the catchment were unlikely to pose an ecological risk. However, little is known about the combined effects of simultaneous, low-level exposure of multiple herbicides of the same mode of action on Australian aquatic organisms nor their contribution when found in mixtures with other pesticides. Further research is required to adequately assess the risk of pesticides in Victorian aquatic environments.

  14. Peat in horticulture and conservation: the UK response to a changing world

    Directory of Open Access Journals (Sweden)

    P.D. Alexander

    2008-11-01

    Full Text Available Peat bogs are increasingly recognised as valuable habitats for wildlife and important stores of carbon. Yet the UK horticultural industry relies heavily on peat sourced from bogs in the UK and Republic of Ireland. Environmentalists, government and horticultural businesses in the UK now recognise the environmental consequences of using peat in horticulture, and the industry is turning increasingly to sustainable raw materials. In this paper, the strengths and weaknesses of campaigning since 1990 to implement this change are analysed, with the intention of providing useful information for other countries facing similar challenges. The campaign encountered deeply-ingrained practices so that the shift in behaviour has been slow and, although now widespread, still meets resistance in some quarters. The UK Government introduced targets for peat replacement which have helped stimulate the industry to develop suitable alternatives. The major gardening retailers have included peat replacement targets in their environmental codes of practice, and these are being met through incremental peat dilution with alternative materials such as green compost and processed timber by-products. Legislative requirements for European biodiversity conservation have led the UK government to terminate peat extraction on significant areas of former commercial extraction. The importance of peatlands for carbon sequestration and the major issue of climate change are increasingly focusing attention on peatland conservation, pointing towards the need for a more consistent approach to the use of peat across the European Community.

  15. Pesticide Exposure and Health Problems Among Female Horticulture Workers in Tanzania

    Directory of Open Access Journals (Sweden)

    Ezra Jonathan Mrema

    2017-06-01

    Full Text Available Commercialization of horticulture farming, expansion of farms, and the practice of monoculture favor the proliferation of pests, which in turn increases the need for pesticides. Increased exposure to pesticides is associated with inadequate knowledge on the hazardous nature of pesticides, poor hygiene practices, lack of availability of washing facilities, and insufficient adherence to precautionary instructions on pesticide labels. Mitigating the risks posed by pesticides is considered a less compelling interest than alleviating poverty. Women working in horticulture in Tanzania usually have low levels of education and income and lack decision-making power even on matters relating to their own health. This contributes to pesticide exposure and other health challenges. Because of multiple factors, some of which act as study confounders, few studies on exposure to pesticides and health effects have been conducted among women. This review identified factors that contribute to the increased health effects among women working in the horticultural industry and how these effects relate to pesticide exposure.

    2016-09-01

    Full Text Available Identification of potential areas in an agricultural sector is needed in order to meet the national food needs, among others, by carrying out mapping the potential areas through clustering the Kabupaten-Kota in Indonesia, especially on imported agricultural commodities of food crops and horticultures. The use of cluster analysis with top-down clustering method (K-means produces the best cluster. Of 268 regencies-cities, there are 7 clusters, namely Cluster 1 consisting of 154 regencies, Cluster 2 consisting of 2 regencies, Cluster 3 consisting of only1 regency, Cluster 4 consisting of 8 regencies, Cluster 5 consisting of 24 regencies, Cluster 6 consisting of 75 regencies, and Cluster 7 consisting of 4 regencies. Each cluster has its own dominant commodity characteristics.  The results of typology klassen on constructed clusters show that food crop and horticulture commodities have grown well and fast. Out of 13 commodities, there are 7 major commodities: Cluster 1: rice and corns; Clusters 2, 3 and 7: cassava; Cluster 4: corns, cassavas and chilly; Cluster 5: apples; Cluster 6: corns, shallots, and garlic. Six other commodities do not grow well, namely sorghum, potatoes, soybeans, peanuts, oranges, and grapes. The potential lack of an area is due to the plants’ low productivity, which is mainly because of plant pests, highly operational cost, climates and natural disasters. Keywords: imports, food crops, horticulture, cluster, and leading sector.

  17. Biochar for Horticultural Rooting Media Improvement: Evaluation of Biochar from Gasification and Slow Pyrolysis

    Directory of Open Access Journals (Sweden)

    Chris Blok

    2017-01-01

    Full Text Available Peat is used as rooting medium in greenhouse horticulture. Biochar is a sustainable alternative for the use of peat, which will reduce peat derived carbon dioxide emissions. Biochar in potting soil mixtures allegedly increases water storage, nutrient supply, microbial life and disease suppression but this depends on feedstock and the production process. The aim of this paper is to find combinations of feedstock and production circumstances which will deliver biochars with value for the horticultural end user. Low-temperature (600 °C–750 °C gasification was used for combined energy and biochar generation. Biochars produced were screened in laboratory tests and selected biochars were used in plant experiments. Tests included dry bulk density, total pore space, specific surface area, phytotoxicity, pH, EC, moisture characteristics and microbial stability. We conclude that biochars from nutrient-rich feedstocks are too saline and too alkaline to be applied in horticultural rooting media. Biochars from less nutrient-rich feedstocks can be conveniently neutralized by mixing with acid peat. The influence of production parameters on specific surface area, pH, total pore space and toxicity is discussed. Biochar mildly improved the survival of beneficial micro-organisms in a mix with peat. Overall, wood biochar can replace at least 20% v/v of peat in potting soils without affecting plant growth.

    2012-06-01

    The Organising Committee recognised from the outset, the need to provide a forum not just for scientific presentation, but for open discussion and dialogue around the policy and political issues, as well as the science that drives the One Health agenda. The Committee was also cognizant of the need to embrace a definition of One Health that includes food security and food safety and included the social and economic pressures that shapes this area. The meeting was therefore organised under four themes with plenary sessions followed by breakout parallel sessions for each of these. The themes covered Disease Emergence, Environmental Drivers, Trade, Food Security and Food Safety, and Science Policy and Political Action. The plenary session commenced with one or two keynote presentations by world leaders on the topic being covered, followed by panel discussions involving six to eight experts and involving all participants at the congress. Each of the panel members spoke briefly on the topic covered by the keynote speaker and were asked to be as provocative as possible. The discussions that followed allowed debate and discussion on the keynote presentations and the panel members comments. This was followed by six to eight parallel breakout sessions involving in depth papers on the session’s topic. Throughout the conference at various times, sponsored sessions dealt with particular areas of science or policy providing a further framework not only to learn current science but for debate and discussion. A full copy of all abstracts is available on the web at http://www.springerlink.com. In concluding the Congress recognised the interdependence of, and seeks to improve human, animal and environmental health; recognised that communication, collaboration and trust between human and animal health practitioners is at the heart of the One Health concept; agreed that a broad vision that includes other disciplines such as economics and social behaviour is essential to success.

    1993-01-01

    The contributions in this book were presented at the Fourth International Geostatistics Congress held in Tróia, Portugal, in September 1992. They provide a comprehensive account of the current state of the art of geostatistics, including recent theoretical developments and new applications. In particular, readers will find descriptions and applications of the more recent methods of stochastic simulation together with data integration techniques applied to the modelling of hydrocabon reservoirs. In other fields there are stationary and non-stationary geostatistical applications to geology, climatology, pollution control, soil science, hydrology and human sciences. The papers also provide an insight into new trends in geostatistics particularly the increasing interaction with many other scientific disciplines. This book is a significant reference work for practitioners of geostatistics both in academia and industry.

    A 5% cut in fusion research budgets will force some programs to be dropped in order to keep the large machinery running unless US and European scientists collaborate instead of competing. Legislators became uneasy about the escalating costs of the new devices. The 1984 budget of $470 million for magnetic fusion research is only half the projected cost of the Tokomak Fusion Core Experiment (TFCX) planned to ignite, for the first time, a self-sustaining burn. Planning for the TCFX continued despite the message from Congress. Work at the large institutions at Princeton, MIT, etc. may survive at the expense of other programs, some of which will lose academic programs as well. Scientists point to the loss of new ideas and approaches when projects are cancelled. Enthusiasm is growing for international collaboration

    The conference proceedings consist of approximately 120 technical papers presented at the Seventh International Geostatistics Congress held in Banff, Alberta, Canada in 2004. All the papers were reviewed by an international panel of leading geostatisticians. The five major sections are: theory, mining, petroleum, environmental and other applications. The first section showcases new and innovative ideas in the theoretical development of geostatistics as a whole; these ideas will have large impact on (1) the directions of future geostatistical research, and (2) the conventional approaches to heterogeneity modelling in a wide range of natural resource industries. The next four sections are focused on applications and innovations relating to the use of geostatistics in specific industries. Historically, mining, petroleum and environmental industries have embraced the use of geostatistics for uncertainty characterization, so these three industries are identified as major application areas. The last section is open...

  4. Organizing Capacities and Union Priorities in the Hotelsector in Oslo, Dublin, and Toronto

    Full Text Available In this article, we draw international comparisons between industrial relations regimes in the hotel sector and compare relevant trade union experiences in the selected metropolitan areas of Oslo, Dublin, and Toronto. We ask how union strategies differ in these different hotel markets, and how strategic choices at a local level relate to industrial relations models, regulatory change, and corporate restructuring in the hotel market. The study is based on interviews with union representatives and key informants in Norway, Ireland, and Canada. The main argument we make is that the reorientation of union priorities and the willingness to engage in innovative strategies that has characterized hotel unionism in Toronto and Dublin is not detectable in the case of Oslo. This might be a result of the relatively strong position Norwegian trade unions have in national industrial relations, but can at the same time leave local hotel unions vulnerable as they are facing low unionization levels and corporate restructuring which they are unable to tackle effectively.

  5. Feasibility analysis for a SolarShare co-operative in the City of Toronto

    2007-01-01

    This report provided details of a feasibility study conducted to assess a business model for a solar electric co-operative within the City of Toronto. The study focused on the development of a rooftop array of solar photovoltaic (PV) panels. A portfolio of potential partners and projects representing approximately 4 MW was identified. Economic and financial models were used to determine the viability of the SolarShare rooftop design. Various tariffs and subsidies currently available for the development of renewable energy projects were reviewed. Despite growing environmental awareness and enthusiasm for solar energy projects amongst Toronto inhabitants, the analysis demonstrated that rooftop PV projects in Ontario are not profitable without a reduction in the costs of $3,500 to $5000 kW, subsidies, or an increase in tariff payments under the province's standard offer contract program. Revenues derived from energy sales under the SolarShare program were approximately half of what was required to undertake a profitable investment in solar PV. Recommendations for building profitable PV systems using a staged approach were included. 27 refs., 16 tabs., 1 fig

    While tuberculosis (TB) in Canadian cities is increasingly affecting foreign-born persons, homeless persons remain at high risk. To assess trends in TB, we studied all homeless persons in Toronto who had a diagnosis of active TB during 1998-2007. We compared Canada-born and foreign-born homeless persons and assessed changes over time. We identified 91 homeless persons with active TB; they typically had highly contagious, advanced disease, and 19% died within 12 months of diagnosis. The proportion of homeless persons who were foreign-born increased from 24% in 1998-2002 to 39% in 2003-2007. Among foreign-born homeless persons with TB, 56% of infections were caused by strains not known to circulate among homeless persons in Toronto. Only 2% of infections were resistant to first-line TB medications. The rise in foreign-born homeless persons with TB strains likely acquired overseas suggests that the risk for drug-resistant strains entering the homeless shelter system may be escalating.

  7. Energy Solutions, Neo-Liberalism, and Social Diversity in Toronto, Canada

    2011-01-01

    In response to the dominance of green capitalist discourses in Canada’s environmental movement, in this paper, we argue that strategies to improve energy policy must also provide mechanisms to address social conflicts and social disparities. Environmental justice is proposed as an alternative to mainstream environmentalism, one that seeks to address systemic social and spatial exclusion encountered by many racialized immigrants in Toronto as a result of neo-liberal and green capitalist municipal policy and that seeks to position marginalized communities as valued contributors to energy solutions. We examine Toronto-based municipal state initiatives aimed at reducing energy use while concurrently stimulating growth (specifically, green economy/green jobs and ‘smart growth’). By treating these as instruments of green capitalism, we illustrate the utility of environmental justice applied to energy-related problems and as a means to analyze stakeholders’ positions in the context of neo-liberalism and green capitalism, and as opening possibilities for resistance.

    The agriculture sector is rapidly warming to the idea of algae culture. Arable farmers, livestock farmers and greenhouse growers are all interested. This report contains an elaborated plan for a pilot-scale practical test and three appendices. The two-year pilot is going to cost about EUR 1 million and will yield practical knowledge about using algae to purify drainwater from greenhouse horticulture. A partnership between numerous small algae growers in a sales cooperative should lead to a better market position. Appendix 1 gives a description of various algae systems and the different types of algae that can currently be cultivated. Chlorella and Arthrospira are the most suitable types for cultivation on greenhouse drainwater. The most economically viable choice appears to be a hybrid nursery with a photobioreactor for starter material and covered raceways for mass production. Appendix 2 gives specific options for combining greenhouse horticulture and algae culture, including the surface allocated to, respectively, algae culture and greenhouse horticulture. Appendix 3 gives the detailed findings of research conducted by Imares into algae on drainwater specifically for the oyster growing sector [Dutch] De belangstelling van het agrarisch bedrijfsleven voor de algenteelt groeit snel.

    2010-10-14

    To determine the prevalence and risks of early childhood caries (ECC) among children less than 71 months of age in Toronto, Canada, and to evaluate the association between parental/caregiver depression and ECC. A secondary analysis of data previously collected by the Toronto Public Health as part of the 2003 Toronto Perinatal and Child Health Survey was performed. The 90-item survey was conducted over the telephone to 1,000 families with children from zero years (birth) to six years of age. Parents/caregivers were asked about factors related to the development and health of their children. For this study, only children younger than six years of age (less than 71 months) were included (n=833). The primary outcome of interest was self-reported and measured by the response to the question of whether a physician/dentist had ever told the parent/caregiver his/her child had ECC. The prevalence of ECC was 4.7 percent (37 of 791 children). The child's age, his/her history of dental visits, teeth brushing, the use of fluoridated toothpaste, the parent's/caregiver's depressive tendencies, the language spoken at home, and the household annual income were all significant in the bivariate analysis. Multiple logistic regression identified four factors associated with ECC: the child's age (being three years of age or older), having at least one parent/caregiver with depression, not speaking English at home, and having an annual household income less than $40,000 in Canadian dollars (CAD). While a child's age, home language, and household income are known risks for ECC, the finding that parental/caregiver depression may be related to ECC is new. Multiple risk factors are involved in the development of early childhood caries. Of particular importance are demographic (e.g., child's age), social (e.g., annual household income), and psychosocial factors (e.g., parental/caregiver depression) that are indirectly linked to ECC. More attention needs to be placed on understanding the role

    This paper is a report of a study conducted to assess change in depression severity, perceived attentional capacity and rumination (brooding) in individuals with clinical depression during a therapeutic horticulture programme and to investigate if the changes were mediated by experiences of being away and fascination. Individuals with clinical depression suffer from distortion of attention and rumination. Interventions can help to disrupt maladaptive rumination and promote restoration of depleted attentional capacity. A single-group study was conducted with a convenience sample of 28 people with clinical depression in 2009. Data were collected before, twice during, and immediately after a 12-week therapeutic horticulture programme, and at 3-month follow-up. Assessment instruments were the Beck Depression Inventory, Attentional Function Index, Brooding Scale, and Being Away and Fascination subscales from the Perceived Restorativeness Scale. Mean Beck Depression Inventory scores declined by 4.5 points during the intervention (F = 5.49, P = 0.002). The decline was clinically relevant for 50% of participants. Attentional Function Index scores increased (F = 4.14, P = 0.009), while Brooding scores decreased (F = 4.51, P = 0.015). The changes in Beck Depression Inventory and Attentional Function Index scores were mediated by increases in Being Away and Fascination, and decline in Beck Depression Inventory scores was also mediated by decline in Brooding. Participants maintained their improvements in Beck Depression Inventory scores at 3-month follow-up. Being away and fascination appear to work as active components in a therapeutic horticulture intervention for clinical depression.

    Vegetable production systems are characterized by intense pesticide use, yet the effects on the surrounding environment are largely unknown and need to be studied. Given this knowledge gap, the objective of this work is to determine the impact of horticulture on a representative watercourse by conducting an integrated study of the occurrence and concentration of pesticides in bottom sediments and their relation to lethal and sublethal effects on benthic fauna. Two sampling campaigns were conducted during seasons of low and high pesticide application in five sites along the Carnaval creek, located in the peri-urban area of La Plata City (Buenos Aires, Argentina). The samples were tested for 36 pesticide compounds by GC-MS and LC-MS, and whole-sediment laboratory toxicity tests were performed using the native amphipod Hyalella curvispina. The results showed a general but variable distribution in the concentrations detected along the stream. For each sampling campaign (first/second), the total pesticide loads, measured as the sum of herbicides, insecticides and fungicides, were 1080/2329, 3715/88, and 367/5ngg -1 dw, respectively. Lethal and sublethal effects were observed in both sampling campaigns. In order to correlate both sets of results, data were assessed by multivariate analysis, including principal component analysis. The observed toxicity was considered to be mainly due to insecticides; thus, horticultural practices have an impact on nearby watercourses and can potentially endanger the benthic fauna. This is the first study in Argentina to assess the impact of pesticides on aquatic environments close to horticultural production areas. Copyright © 2017 Elsevier B.V. All rights reserved.

  20. Perception and understanding of invasive alien species issues by nature conservation and horticulture professionals in Belgium.

    We conducted a survey to determine how two professional sectors in Belgium, horticulture professionals and nature reserve managers (those directly involved in conservation), view the issues associated with invasive plant species. We developed and utilized a questionnaire that addressed the themes of awareness, concept and use of language, availability of information, impacts and, finally, control and available solutions. Using co-inertia analyses, we tested to what extent the perception of invasive alien species (IAS) was dependent upon the perception of Nature in general. Only forty-two percent of respondent horticulture professionals and eighty-two percent of nature reserve managers had a general knowledge of IAS. Many individuals in both target groups nonetheless had an accurate understanding of the scientific issues. Our results therefore suggest that the manner in which individuals within the two groups view, or perceive, the IAS issue was more the result of lack of information than simply biased perceptions of target groups. Though IAS perceptions by the two groups diverged, they were on par with how they viewed Nature in general. The descriptions of IAS by participants converged with the ideas and concepts frequently found in the scientific literature. Both managers and horticulture professionals expressed a strong willingness to participate in programs designed to prevent the spread of, and damage caused by, IAS. Despite this, the continued commercial availability of many invasive species highlighted the necessity to use both mandatory and voluntary approaches to reduce their re-introduction and spread. The results of this study provide stakeholders and conservation managers with practical information on which communication and management strategies can be based.

    Hemlock woolly adelgid, Adelges tsugae Annand (Hemiptera: Adelgidae), is an exotic pest of eastern hemlock, Tsuga canadensis (L.) Carrière (Pinales: Pinaceae), in the eastern United States. Two commonly used insecticides to manage adelgid are imidacloprid, a systemic neonicotinoid insecticide, and horticultural oil, a refined petroleum oil foliar spray. We have investigated the influence of imidacloprid and horticultural oil on spider abundance at different canopy strata in eastern hemlock. In total, 2,084 spiders representing 11 families were collected from the canopies of eastern hemlock. In beat-sheet and direct observation samples, the families Theridiidae, Araneidae, Salticidae, and Anyphaenidae were the most abundant. Significantly higher numbers of spiders were recorded on untreated control trees compared with trees treated with imidacloprid using soil drench and soil injection applications. Spider abundance in trees injected with imidacloprid and horticultural oil applications did not significantly differ from control trees. Spider abundance was significantly greater in the top and middle strata of the canopy than in the bottom stratum, where imidacloprid concentrations were the highest. Regression analysis showed that spider abundance was inversely associated with imidacloprid concentration. This research demonstrates that imidacloprid, when applied with selected methods, has the potential to result in reductions of spider densities at different strata. However, slight reductions in spider abundance may be an acceptable short-term ecological impact compared with the loss of an untreated hemlock and all the associated ecological benefits that it provides. Future studies should include investigations of long-term impact of imidacloprid on spiders associated with eastern hemlock.

    2001-06-01

    The City of Toronto Environmental Plan was adapted in principle by City Council in April 2000. The Plan contains 66 recommendations on land, air, water, governance, sustainability, energy, transportation, green economic development and monitoring. As part of the actions on air, the Plan recommended that the City develop a comprehensive strategy to make Toronto's air clean and free of harmful levels of pollutants. This document reports on progress in the development of this comprehensive air quality standard. Work on the standards was undertaken by an Air Quality Strategy Interdepartmental Working Group (AQSI Working Group) consisting of city departmental representatives, which is one of several working groups reporting to the Toronto Interdepartmental Environmental Team (TIE). While the AQSI Working Group has not yet concluded its work, it is able to report a number of preliminary conclusions. Among them are: implementation of several successful city-wide programs. In this context preliminary indications are that program effectiveness will be limited by the availability of staff and appropriate funding. Policy and legal studies that will provide essential information relating to the legal/jurisdictional context are well underway. Modelling and monitoring of Toronto's air quality are in progress, and will be relied upon for information to guide policy development. Final strategy will have to be formulated in a regional context, in concert with the provincial and federal governments, and will have to take into account trans-boundary (inter-regional, inter-provincial and international) issues

    Howard, Frazer; McKneally, Martin F; Levin, Alex V

    2010-06-01

    Bioethics training is a vital component of postgraduate medical education and required by accreditation organizations in Canada and the United States. Residency program ethics curricula should ensure trainees develop core knowledge, skills, and competencies, and should encourage lifelong learning and teaching of bioethics. Many physician-teachers, however, feel unprepared to teach bioethics and face challenges in developing and implementing specialty-specific bioethics curricula. The authors present, as one model, the innovative strategies employed by the University of Toronto Joint Centre for Bioethics. They postulate that centralized support is a key component to ensure the success of specialty-specific bioethics teaching, to reinforce the importance of ethics in medical training, and to ensure it is not overshadowed by other educational concerns.

    Hewer, Micah J.; Gough, William A.

    2016-11-01

    Based on a case study of the Toronto Zoo (Canada), multivariate regression analysis, involving both climatic and social variables, was employed to assess the relationship between daily weather and visitation. Zoo visitation was most sensitive to weather variability during the shoulder season, followed by the off-season and, then, the peak season. Temperature was the most influential weather variable in relation to zoo visitation, followed by precipitation and, then, wind speed. The intensity and direction of the social and climatic variables varied between seasons. Temperatures exceeding 26 °C during the shoulder season and 28 °C during the peak season suggested a behavioural threshold associated with zoo visitation, with conditions becoming too warm for certain segments of the zoo visitor market, causing visitor numbers to decline. Even light amounts of precipitation caused average visitor numbers to decline by nearly 50 %. Increasing wind speeds also demonstrated a negative influence on zoo visitation.

    Full Text Available Alexithymia can be defined as inability to identify and describe emotions in the self. Has shown to be related to several psychological and pathological processes that can result in unsatisfactory interpersonal relationships and decreased social adjustment. Advances in research of alexithymia require the development and validation of assessment instruments, and its application to different population. With this aim, we studied the psychometric properties of the Twenty-Item Toronto Alexithymia Scale (TAS-20 in Chilean population using various modeling procedures (e.g., CFA, ESEM in different structures (i.e., Correlated, Unidimensional, Hierarchical or Wording factors. Among the 10 models tested, the four-dimensional structure offered the best fit but with item-loading problems in the last factor (Pragmatic Thinking. We suggest that the studied version of the scale needs improvement (theoretical and empirical to ensure optimal indices of validation for Chilean population.

    2015-03-01

    Within the areas of literature on both population aging and health and homelessness, little attention has been given to the opportunities and barriers to healthy aging among older persons with a history of homelessness. Set in the context of inner-city Toronto, Canada, this article reports on the findings from qualitative interviews with 29 formerly homeless older persons. The findings illustrate participants' experiences of positive health change since moving into a stable housing environment and the aspects of housing they perceive to have improved their health and wellbeing. The qualitative findings also draw attention to the ongoing barriers to healthy aging that can be experienced among older persons with a history of homelessness. Overall, this study draws on the lived experiences of formerly homeless older persons to offer a better understanding of the long-term effects of homelessness on health, wellbeing, and aging.

    Although youth probation (in some countries described as youth justice or youth offending work) has been widely discussed in older and more recent criminological literature, less attention has been paid to youth probation officers' accounts of their attitudes and strategies. In this study, the author uses in-depth interviews with 20 youth probation officers in Toronto, examining officers' attitudes toward the youth they work with and how these attitudes are reflected in the strategies that the officers use to achieve their professional goals. Findings reveal that the officers balance their authoritative and supportive roles not only to hold youth accountable, to encourage them to assert control over their lives, and to maintain optimism about the possibility of a nondeviant life, but also to assist the youth in attaining the means and resources necessary to make positive changes. These findings are interpreted within the framework of Canadian youth justice legislation as well as the broader desistance literature.

    The Toronto Structured Interview for Alexithymia (TSIA) was developed to provide a structured interview method for assessing alexithymia. One drawback of this instrument is the amount of time it takes to administer and score. The current study used item response theory (IRT) methods to analyze data from a large heterogeneous multi-language sample (N = 842) to investigate whether a subset of items could be selected to create a short version of the instrument. Samejima's (1969) graded response model was used to fit the item responses. Items providing maximum information were retained in the short model, resulting in the elimination of 12-items from the original 24-items. Despite the 50% reduction in the number of items, 65.22% of the information was retained. Further studies are needed to validate the short version. A short version of the TSIA is potentially of practical value to clinicians and researchers with time constraints. Copyright © 2018. Published by Elsevier B.V.

    The paper presents the results of an empirical study of the change in perception of air quality in Toronto, Canada from 1968-1978. The data show a shift in public concern with and awareness of air quality. Despite the fact that the 1978 population regarded air quality as degraded, air pollution declined as a public concern, requiring a less serious response by government than other societal problems. The results of the study were reviewed in the context of existing perception studies. In explaining change, the study found: (1) perception of ambient air quality was not related to air pollution levels; (2) air pollution declines as a public concern as other socioeconomic problems surface; and (3) the mass media has an important role in affecting public attitudes and behavior over environmental quality issues.

    Previously the DEXA system used in this research has been deployed commercially in meat processing plants with the objective of accurately determining the fat content of bulk and packaged meat, through a JV with ANZCO Foods and a partnership with Smiths Detection. This present research is aimed at demonstrating an ability to measure the dry matter distribution and in turn the net dry matter for individual horticultural products using DEXA. The DEXA images are obtained while scanning the products on a conveyor belt running at speeds representative of production grading situations. The products reported on here are primarily potatoes (because of a direct commercial interest), but also a butternut pumpkin and two rock melons. The grading and dry matter measurement capability is based on detecting change in the effective atomic number (EAN) with change in the elemental proportions within the product and there being effectively a binary mixture (e.g dry matter and water) present. Grading of fruit and vegetables on this basis is expected to be challenging. The commercial meat/fat grading already commercialised as a DEXA system is associated with 1.8 EAN units difference between fat (carbon rich Z eff =5.8) and fully-lean meat (oxygen rich Z eff =7.6) but this range is large compared to what is expected for horticultural products. The dry matter in horticultural products is primarily starch (plus minerals) and the EAN difference between starch (and minerals) and water is unknown here but calculations give the difference as little as 0.2 EAN units, dependant on the mineral content in the product. In this work we show that the dry matter sensitivities of the DEXA technology for horticultural products is discernable allowing measurement of dry matter distributions, and net dry matter values. The EAN range is indeed much smaller than for fat/meat mixtures, and consistent differences are yet to be demonstrated for an assembly of product, except for potatoes where consistency

    The process of selecting different peat types for horticultural purposes involves many physical and chemical determinations. Infrared spectroscopy could be used together with the usual methods for the evaluation of peat quality. Due to the fact that different peats contain different amounts of infrared absorbing functional groups, each peat produces a characteristic spectrum. From the spectrum, one may determine the botanical composition, degree of humification, ash content, cation exchange capacity, nitrogen content and carbon content, of the natural peat. The spectrum also shows whether the peat has been fertilized and limed and in some cases the presence of mineral soil or wetting agent mixed in the peat may be detected

    2012-09-01

    Full Text Available Plants subjected to abiotic stresses synthesize secondary metabolites with potential application in the functional foods, dietary supplements, pharmaceutical, cosmetics and agrochemical markets. This approach can be extended to horticultural crops. This review describes previous reports regarding the effect of different postharvest abiotic stresses on the accumulation of phenolic compounds. Likewise, the physiological basis for the biosynthesis of phenolic compounds as an abiotic stress response is described. The information presented herein would be useful for growers and the fresh produce market which are interested in finding alternative uses for their crops, especially for those not meeting quality standards and thus are considered as waste.

    Concentrations of organobromine (BFRs), organochlorine (CFRs) and organophosphate esters flame retardants and plasticizers (PFRs) in air were monitored for over one year at an urban site in Toronto, Canada during 2010-2011. The mean value for polybrominated diphenyl ethers (BDEs) (gas + particle phase) was 38 pg/m3 with BDE-47 and BDE-99 as the dominant congeners. The mean concentrations in air for ∑non-BDE (BFRs and CFRs), was 9.6 pg/m3 - about four times lower than the BDEs. The brominated FRs: TBP-AE, BTBPE, EH-TBB, BEH-TEBP and the chlorinated syn- and anti-DP were detected frequently, ranging from 87% to 96%. Highest concentrations in air among all flame retardant classes were observed for the Σ-PFRs. The yearly mean concentration in air for ΣPFRs was 2643 pg/m3 with detection frequency higher than 80%. Except for TBP-AE and b- DBE-DBCH, non-BDEs (BFRs, CFRs and PFRs) were mainly associated with the particle phase. BDE concentrations in air were positively correlated with temperature indicating that volatilization from local sources was an important factor controlling levels in air. This correlation did not hold for most BFRs, CFRs and PFRs which were mainly on particles. For these compounds, air concentrations in Toronto are likely related to emissions from point sources and advective inputs. This study highlights the importance of urban air monitoring for FRs. Urban air can be considered a sentinel for detecting changes in the use and application of FRs in commercial products.

    This study investigated associations between long-term exposure to ambient volatile organic compounds (VOCs) and mortality. 58,760 Toronto residents (≥35 years of age) were selected from tax filings and followed from 1982 to 2004. Death information was extracted using record linkage to national mortality data. Land-use regression surfaces for benzene, n-hexane, and total hydrocarbons were generated from sampling campaigns in 2002 and 2004 and assigned to residential addresses in 1982. Cox regression was used to estimate relationships between each VOC and non-accidental, cardiovascular, and cancer mortality. Positive associations were observed for each VOC. In multi-pollutant models the benzene and total hydrocarbon signals were strongest for cancer. The hazard ratio for cancer that corresponded to an increase in the interquartile range of benzene (0.13 μg/m 3 ) was 1.06 (95% CI = 1.02–1.11). Our findings suggest ambient concentrations of VOCs were associated with cancer mortality, and that these exposures did not confound our previously reported associations between NO 2 and cardiovascular mortality. -- Highlights: ► We studied associations between long-term exposure to volatile organic compounds and mortality. ► The study was a population-based cohort of Toronto adults followed for up to 22 years. ► We used land-use regression estimates of benzene, total hydrocarbons and n-hexane. ► Benzene and total hydrocarbons were positively associated with cancer mortality. ► VOCs did not confound associations between NO 2 and cardiovascular mortality. -- Long-term exposure to ambient benzene was associated with non-accidental and cancer causes of death, and did not attenuate associations between NO 2 and cardiovascular mortality

    The purpose of this research was to assess key stakeholder attitudes regarding menu labelling in Toronto, the largest municipality in Canada. Menu labelling is a population health intervention where food-labelling principles are applied to the eating-out environment through disclosure of nutrient content of food items on restaurant menus at the point of sale. Menu-labelling legislation has been implemented in the United States, but has yet to be adopted in Canada. As provincial voluntary programs and federal analyses progress, municipal jurisdictions will need to assess the feasibility of moving forward with parallel interventions. Data were collected and analyzed in late 2011 to early 2012, including: a consumer eating-out module incorporated into a public health surveillance telephone survey (n=1,699); an online survey of independent restaurant operators (n=256); in-depth key informant interviews with executives and decision makers at chain restaurants (n=9); and a policy consultation with local restaurant associations. Toronto residents, particularly men, younger adults, and those with higher income or education, frequently eat out. A majority indicated that nutrition information is important to them; 69% note that they currently use it and 78% reported they would use it if it were readily available. Resistance to menu-labelling requirements at the municipal level was articulated by franchise/chain restaurant executives and industry associations. Despite overall low interest among independent restaurant operators, 57% reported feeling some responsibility to provide nutrition information and 50% believed it could be good for business. This research supports earlier literature that indicates strong public support for menu labelling alongside perceived barriers among the restaurant and foodservices sector. Leverage points for effective operator engagement for menu-labelling adoption were identified, nonetheless, highlighting the need for public health support.

    Environmental horticulture firms provide a variety of commercial/residential landscape products and services encompassing ornamental plant production, design, installation, and maintenance. The companies generate tons of waste including plastic containers, trays, and greenhouse/field covers, creating the need to reduce and utilize plastic waste. Based on survey data collected in Georgia in 2013, this paper investigates determinants of the environmental horticulture firms' recycling decision (plastic containers, flats, and greenhouse poly). Our findings indicate that the decision to discard vs. recycle plastic containers, flats, and greenhouse poly is significantly influenced by firm scope, size, location, and partnership with recycling providers, as well as whether recycling providers offer additional waste pickup services. Insights from this study are of use to local governments and environmental organizations interested in increasing horticultural firm participation in recycling programs and lowering the volume of plastic destined for landfills.

    Understanding the fundamental nature of a molecular process or a biological pathway is often a catalyst for the development of new technologies in biology. Indeed, studies from late 1990s to early 2000s have uncovered multiple overlapping but functionally distinct RNA silencing pathways in plants, including the posttranscriptional microRNA and small interfering RNA pathways and the transcriptional RNA-directed DNA methylation pathway. These findings have in turn been exploited for developing artificial RNA silencing technologies such as hairpin RNA, artificial microRNA, intrinsic direct repeat, 3' UTR inverted repeat, artificial trans-acting siRNA, and virus-induced gene silencing technologies. Some of these RNA silencing technologies, such as the hairpin RNA technology, have already been widely used for genetic improvement of crop plants in agriculture. For horticultural plants, RNA silencing technologies have been used to increase disease and pest resistance, alter plant architecture and flowering time, improve commercial traits of fruits and flowers, enhance nutritional values, remove toxic compounds and allergens, and develop high-value industrial products. In this article we aim to provide an overview of the RNA silencing pathways in plants, summarize the existing RNA silencing technologies, and review the current progress in applying these technologies for the improvement of agricultural crops particularly horticultural crops.

    This study aimed to assess changes in psychological distress and social participation in adults diagnosed with clinical depression during and after participating in a therapeutic horticulture programme, and to investigate if the changes covaried with levels of group cohesiveness during the intervention. An intervention with a single-group design was repeated with different samples in successive years (pooled n = 46). In each year, five groups of 3-7 participants went through the intervention. Data were collected before, twice during, and immediately after a 12-week therapeutic horticulture programme, as well as at 3-months' follow up. Mental health assessments included the Beck Depression Inventory, the State Subscale of Spielberger State-Trait Anxiety Inventory, the Positive Affect Scale from the Positive and Negative Affect Scale, the Perceived Stress Scale, and the Therapeutic Factors Inventory-Cohesiveness Scale. The analysis of the pooled data confirmed significant beneficial change in all mental health variables during the intervention. Change from baseline in depression severity persisted at 3-months' follow up. Increased social activity after the intervention was reported for 38% of the participants. The groups quickly established strong cohesiveness, and this continued to increase during the intervention. The average level of group cohesiveness correlated positively, but not significantly, with change in all mental health outcome variables. © 2011 The Authors.

    Sickness absenteeism is the major occupational health problem in developing countries where the majority of working population are engaged in hazardous sectors, such as agriculture. However, there is a dearth of studies clarifying the situation in most of Subsaharan African countries, like Ethiopia. The present study determined the magnitude of sickness absenteeism and associated factors among horticulture employees in Lume District, southeast Ethiopia. An institutional-based cross-sectional study was conducted among horticulture employees in Lume District, southeast Ethiopia from March to May 2014. Stratified sampling followed by simple random sampling techniques was used to select the study participants. A pre-tested and structured questionnaire was used to collect data. Multivariable analyses were employed to see the effect of explanatory variables on dependent variable. The magnitude of sickness absenteeism was 58.8 % [95 % CI: (54.9, 62.5)] in the past three months. Absence of periodic medical checkup, working for more than 48 h per week, working overtime, job dissatisfaction, and job stress were factors significantly associated with sickness absenteeism. In this study a relatively higher rate of sickness absenteeism was reported compared to other studies. Interventions to reduce sickness absenteeism should focus on areas, such as periodic medical checkup, monitoring work schedules, improving employees' job satisfaction, and managing job stress.

    Cucumis melo L. that belongs to Cucurbitaceae family ranks among one of the highest valued horticulture crops being cultivated across the globe. Besides its economical and medicinal importance, Cucumis melo L. is a valuable resource and model system for the evolutionary studies of cucurbit family. However, very limited numbers of molecular markers were reported for Cucumis melo L. so far that limits the pace of functional genomic research in melon and other similar horticulture crops. We developed the first whole genome based microsatellite DNA marker database of Cucumis melo L. and comprehensive web resource that aids in variety identification and physical mapping of Cucurbitaceae family. The Cucumis melo L. microsatellite database (CmMDb: http://65.181.125.102/cmmdb2/index.html) encompasses 39,072 SSR markers along with its motif repeat, motif length, motif sequence, marker ID, motif type and chromosomal locations. The database is featured with novel automated primer designing facility to meet the needs of wet lab researchers. CmMDb is a freely available web resource that facilitates the researchers to select the most appropriate markers for marker-assisted selection in melons and to improve breeding strategies.

    Vegetables and fruits are an important part of a healthy food diet, however, the eco-sustainability of the production of these can still be significantly improved. European farmers and consumers spend an estimated €15.5 billion per year on inorganic fertilizers and the production of N-fertilizers results in a high carbon footprint. We investigated if fertilizer type and medium constituents determine microbial nitrogen conversions in organic growing media and can be used as a next step towards a more sustainable horticulture. We demonstrated that growing media constituents showed differences in urea hydrolysis, ammonia and nitrite oxidation and in carbon dioxide respiration rate. Interestingly, mixing of the growing media constituents resulted in a stimulation of the function of the microorganisms. The use of organic fertilizer resulted in an increase in amoA gene copy number by factor 100 compared to inorganic fertilizers. Our results support our hypothesis that the activity of the functional microbial community with respect to nitrogen turnover in an organic growing medium can be improved by selecting and mixing the appropriate growing media components with each other. These findings contribute to the understanding of the functional microbial community in growing media and its potential role towards a more responsible horticulture. © 2016 The Authors.

    Protection against thrips, a common pest in bell pepper horticulture is effectively possible without pesticides by using the commercially available predatory mite Amblyzeius cucumeris (Ac). The prevalence of sensitization to Ac among exposed greenhouse employees and its clinical relevance was studied. Four hundred and seventytwo employees were asked to fill in a questionnaire and were tested on location. Next to RAST, skin prick tests (SPTs) were performed with common inhalant allergens, the storage mite Tyrophagus putrescentiae (Tp) which serves as a temporary food source during the cultivation process and Ac. Furthermore, nasal challenge tests with Ac were carried out in 23 sensitized employees. SPTs positive to Ac were found in 109 employees (23%). Work-related symptoms were reported by 76.1%. Sensitization to Tp was found in 62 employees of whom 48 were also sensitized to Ac. Immunoglobulin (Ig)E-mediated allergy to inhalant allergens appeared to be an important risk factor for sensitization to Ac. Employees with rhinitis symptoms showed a significantly higher response to all Ac doses during the nasal challenge test compared with employees without rhinitis symptoms. The predatory mite Ac is a new occupational allergen in horticulture which can cause an IgE-mediated allergy in exposed employees. It is biologically active on the mucous membranes of the nose and therefore clinically relevant for the development of work-related symptoms.

    The STP Uithoorn will be upgraded to accommodate the treatment of wastewater from a growing population and to meet more stringent nutrient discharge limits in 2006. In 2003 a system choice and preliminary design was made for the upgrading. A special feature is the nutrient rich wastewater flow from the rapidly developing horticulture in the area. Since the future loads from horticulture are highly uncertain, flexibility of the STP after upgrading is an important issue. A three stage system was selected: improved physical-chemical primary treatment, secondary treatment by activated sludge, and tertiary treatment by denitrifying filters. In this way an important part of the existing infrastructure can be reused, and flexibility is assured by constructing the tertiary treatment in modules and by providing a wide range of operational control possibilities. In this paper the process of system choice and selection of type of tertiary treatment are described, as well as the optimisation of the existing treatment. In order to determine the feasibility of allowing a high loading rate on the existing secondary clarifiers, a two-dimensional hydraulic model of the clarification process was used.

    A monitoring program of nitrate, nitrite, potassium, sodium, and pesticides was carried out in water samples from an intensive horticulture area in a vulnerable zone from north of Portugal. Eight collecting points were selected and water-analyzed in five sampling campaigns, during 1 year. Chemometric techniques, such as cluster analysis, principal component analysis (PCA), and discriminant analysis, were used in order to understand the impact of intensive horticulture practices on dug and drilled wells groundwater and to study variations in the hydrochemistry of groundwater. PCA performed on pesticide data matrix yielded seven significant PCs explaining 77.67% of the data variance. Although PCA rendered considerable data reduction, it could not clearly group and distinguish the sample types. However, a visible differentiation between the water samples was obtained. Cluster and discriminant analysis grouped the eight collecting points into three clusters of similar characteristics pertaining to water contamination, indicating that it is necessary to improve the use of water, fertilizers, and pesticides. Inorganic fertilizers such as potassium nitrate were suspected to be the most important factors for nitrate contamination since highly significant Pearson correlation (r = 0.691, P < 0.01) was obtained between groundwater nitrate and potassium contents. Water from dug wells is especially prone to contamination from the grower and their closer neighbor's practices. Water from drilled wells is also contaminated from distant practices.

    Climate in Finland offers challenging conditions for commercial horticulture. The short and insufficient growing season together with risky overwintering strongly limits species suitable for cultivation. The aim of this study was to examine the climatic conditions around Finland in the aspect of horticulture, focusing on processes relevant to woody plants and species with photoperiod controlled growth cessation, and how these conditions may be expected to change due to the projected global warming. For this, a set of temperature-related indices and threshold events were used. These indices represent the severity of coldness during winter, wintertime thaws, and frost events close to the onset and ending of the growing season. The combined results of 19 GCMs (General Circulation Model) from the CMIP3 (Coupled Model Intercomparison Project 3) multi-model data set under SRES-B1 and SRES-A2 (Special Report on Emission Scenarios) emission scenarios were used to produce the future projections. By mid-century our results suggest wintertime conditions with reduced cold stress, caused by less frequent and shorter periods of severe frost together with a rise in the extreme minimum temperature. Conversely, an increase in the number and intensity of wintertime thaw events leads to a higher risk in overwintering. Also the risk of spring frost damage is projected to decrease slightly, and the conditions for cold hardening process to improve, as the first autumnal frosts occur later. (orig.)

  18. Reduction of energy usage in postharvest horticulture through management of ethylene.

    Wills, Ron B H; Golding, John B

    2015-05-01

    Cool chain management is the preferred technology to extend the postharvest life of horticultural produce, but with rising energy costs and community pressure to reduce greenhouse gas emissions, there is a need to use less energy-intensive technologies. Minimising the level of ethylene around horticultural produce inhibits ripening and senescence and therefore has the potential to reduce the use of refrigeration. The long-distance transport of bananas within Australia and from Central America to Europe is used as a case study to show that the need for refrigeration could be reduced if the appropriate concentrations of ethylene were maintained around fruit during transit. Data are also presented to show a similar benefit of ethylene control with green beans, as well as another study showing that apples treated with the ethylene action inhibitor 1-methylcyclopropene could be stored at a higher temperature without loss of quality to the consumer. The range of technologies available to manage ethylene levels is discussed. © 2014 Society of Chemical Industry.

  19. Jodï horticultural belief, knowledge and practice: incipient or integral cultivation?

    Directory of Open Access Journals (Sweden)

    2012-08-01

    Full Text Available This paper describes the Jodï horticultural system, including belief, knowledge and practice aspects. The horticulturalpractices of the Jodï were previously characterized as ‘incipient cultivation’ but such practices were poorly described anddocumented. The antiquity of cultivation among this group is suggested by the prominence and significance of horticulturalproducts and techniques in myth and ritual. Our field observations uncovered a fairly sophisticated system of plantmanagement in swiddens, house gardens, trail gardens and natural forest gaps. An inventory of 67 cultivated plant specieswas documented, of which 36 are utilized for food, 20 for magical or medicinal purposes, and 11 for technology. The Jodïprolong the productive phase of their gardens for five years or more through successive planting-harvesting-replantingoperations. Jodï swiddens display an elaborate polycultivated appearance and they possess at least five principal crops:plantain/banana, maize, yams, sweet potato, and sweet manioc. Another distinctive feature is the extensive use of naturalgaps in the forest canopy as cultivation zones. The results of this study suggest that while Jodï horticultural practice iswell integrated with a nomadic, foraging-dependent lifestyle, nevertheless this system does not deserve to be labeled as‘incipient’ and instead is more integral than was recognized previously.

    Due to a rapidly ageing population in the world, it is increasingly pertinent to promote successful ageing strategies which are cost-effective, easily accessible, and more likely to be acceptable to the elderly. Past research associates exposure to natural environments and horticultural therapy (HT) with positive psychological, social and physical health benefits. This Randomized Controlled Trial (RCT) is designed to evaluate the efficacy of HT in promoting Asian elderly' mental health, cognitive functioning and physical health. 70 elderly participants aged 60 to 85 years old will be randomized to participate in either the active horticultural therapy group or be in the waitlist control. Sessions will be weekly for 12 weeks, and monthly for 3 months. Mental health will be assessed through self-reports of depressive and anxiety symptomatology, life satisfaction, social connectedness and psychological well-being, collaborated with immunological markers. Outcome measures of cognitive functioning and physical health include neuropsychological tests of cognitive function and basic health screening. Outcomes will be assessed at baseline, 3 months and 6 months post-intervention. This RCT comprehensively investigates the efficacy of a non-invasive intervention, HT, in enhancing mental health, cognitive functioning and physical health. The results have tremendous potential for supporting future successful ageing programs and applicability to larger populations. ClinicalTrials.gov NCT02495194 .

  20. Library of Congress Model, Anaglyph

    Science.gov (United States)

    2004-01-01

    The Shuttle Radar Topography Mission (SRTM) has produced the first high-resolution, near-global elevation dataset of Earth. In recognition of this achievement, and as an illustration of the data, the United States Library of Congress now displays a 'solid terrain model' of Los Angeles and adjacent mountainous terrain. The model was created by carving a high-density foam block using computer-guided drills that referenced the SRTM dataset. The block was then covered with a Landsat satellite image using computer-guided paint guns that referenced both the Landsat image and the SRTM dataset. The view shown here mimics the actual model on display at the Library of Congress and was generated from the same satellite image and elevation data sets. Anaglyph glasses are required to see this view in three-dimensions. Anaglyph glasses cover the left eye with a red filter and cover the right eye with a blue filter. The model shows the Pacific Ocean and Santa Monica Mountains along the Malibu Coast (lower left), San Fernando Valley (left center), downtown Los Angeles (bottom center), San Gabriel and Pomona Valleys (lower right), San Gabriel Mountains (right center to far right), and part of the Mojave Desert (upper right). Colors are enhanced true color with added topographic shading, and elevation differences are exaggerated 1.5 times. The view is toward the north-northwest. The Los Angeles region was chosen for the Library of Congress model because it illustrates so many ways that topography affects the daily lives of people. The region consists of a coastal plain, inland valleys, mountains up to 3068 meters (10,064 feet), and a desert interior. Topography blocks the landward influence of marine airmasses here such that summer temperatures often differ by 40 degrees Fahrenheit (22 C) across this region at a given moment even at similar elevations. Temperatures also typically cool with rising elevation, and winter storms drop most of their moisture in the mountains, leaving

    2018-02-12

    Horticulture was shown to represent a well-being source for older adults, encompassing the physical, mental and social domains. Aim of this pilot study was to contribute to extant literature through the investigation of the quality of experience associated with horticultural versus occupational activities. A group of 11 older residents of a nursing home were involved in a crossover study with a baseline measure. Participants attended weekly horticultural and occupational sessions for two six-week cycles. Experience Sampling Method was administered before the program and after each session, to assess participants' levels of happiness, concentration, sociability, involvement, challenges and stakes, and self-satisfaction. Altogether, 332 self-report questionnaires were collected. Findings showed that participants' levels of the cognitive and motivational variables increased during both activities, but horticulture was also perceived as providing higher challenges and stakes, and improving self-satisfaction. Results can have practical implications for well-being promotion among older adults through meaningful activity engagement. Copyright © 2018 Elsevier Inc. All rights reserved.

    2012-11-01

    Full Text Available The urban and peri-urban families represent 75% of the Mexican population. The poverty and form of feed seem to be associated with obesity, degenerative diseases and malnutrition. Therefore, the aim of this study was to evaluate the eating habits and dietary diversity of Cardel city, Veracruz, Mexico peri-urban families and know the aptitude of families to practice horticulture at home. Dietary diversity was determined using the scoring method of staple foods. Eating habits and aptitude to practice horticulture were obtained by a survey type Likert scale. The 35% of the families presented good eating habits, 19% regular and 46% of households showed poor dietary habits. Dietary diversity was 29.4 ± 8.7 in primary foods. The Likert general index was 2.9 and represented an average availability to practice peri-urban horticulture. Food diversity of families peri-urban is a function of family economic capacity, in contrast, food habits and socioeconomic status are not associated and finally there were identified multiple factors that positively influence the willingness of the mother of family to practice horticulture.

    Full Text Available Abstract Introduction Iranians comprise an immigrant group that has a very different cultural background from that of the mainstream Canadian population and speaks a language other than English or French; in this case mainly Farsi (Persian. Although Iranian immigrants in Toronto receive a high proportion of care from Farsi-speaking family physicians and health care providers than physicians who cannot speak Farsi, they are still not satisfied with the provided services. The purpose of this study was to identify the obstacles and issues Iranian immigrants faced in accessing health care services as seen through the eyes of Iranian health care professionals/providers and social workers working in Greater Toronto Area, Canada. Methods Narrative inquiry was used to capture and understand the obstacles this immigrant population faces when accessing health care services, through the lens of fifty Iranian health care professionals/providers and social workers. Thirty three health care professionals and five social workers were interviewed. To capture the essence of issues, individual interviews were followed by three focus groups consisting of three health care professionals and one social worker in each group. Results Three major themes emerged from the study: language barrier and the lack of knowledge of Canadian health care services/systems; lack of trust in Canadian health care services due to financial limitations and fear of disclosure; and somatization and needs for psychological supports. Conclusion Iranians may not be satisfied with the Canadian health care services due to a lack of knowledge of the system, as well as cultural differences when seeking care, such as fear of disclosure, discrimination, and mistrust of primary care. To attain equitable, adequate, and effective access to health care services, immigrants need to be educated and informed about the Canadian health care system and services it provides. It would be of great benefit to

  16. Risk factors for SARS transmission from patients requiring intubation: a multicentre investigation in Toronto, Canada.

    Directory of Open Access Journals (Sweden)

    Janet Raboud

    Full Text Available BACKGROUND: In the 2003 Toronto SARS outbreak, SARS-CoV was transmitted in hospitals despite adherence to infection control procedures. Considerable controversy resulted regarding which procedures and behaviours were associated with the greatest risk of SARS-CoV transmission. METHODS: A retrospective cohort study was conducted to identify risk factors for transmission of SARS-CoV during intubation from laboratory confirmed SARS patients to HCWs involved in their care. All SARS patients requiring intubation during the Toronto outbreak were identified. All HCWs who provided care to intubated SARS patients during treatment or transportation and who entered a patient room or had direct patient contact from 24 hours before to 4 hours after intubation were eligible for this study. Data was collected on patients by chart review and on HCWs by interviewer-administered questionnaire. Generalized estimating equation (GEE logistic regression models and classification and regression trees (CART were used to identify risk factors for SARS transmission. RESULTS: 45 laboratory-confirmed intubated SARS patients were identified. Of the 697 HCWs involved in their care, 624 (90% participated in the study. SARS-CoV was transmitted to 26 HCWs from 7 patients; 21 HCWs were infected by 3 patients. In multivariate GEE logistic regression models, presence in the room during fiberoptic intubation (OR = 2.79, p = .004 or ECG (OR = 3.52, p = .002, unprotected eye contact with secretions (OR = 7.34, p = .001, patient APACHE II score > or = 20 (OR = 17.05, p = .009 and patient Pa0(2/Fi0(2 ratio < or = 59 (OR = 8.65, p = .001 were associated with increased risk of transmission of SARS-CoV. In CART analyses, the four covariates which explained the greatest amount of variation in SARS-CoV transmission were covariates representing individual patients. CONCLUSION: Close contact with the airway of severely ill patients and failure of infection control practices to prevent exposure

    Adolescence is marked with many changes in the development of higher order thinking skills. As students enter high school they are expected to utilize these skills to solve problems, become abstract thinkers, and contribute to society. The goal of this study was to assess horticultural science knowledge achievement and attitude toward horticulture, science, and school in high school agriculture students. There were approximately 240 high school students in the sample including both experimental and control groups from California and Washington. Students in the experimental group participated in an educational program called "Hands-On Hortscience" which emphasized problem solving in investigation and experimentation activities with greenhouse plants, soilless media, and fertilizers. Students in the control group were taught by the subject matter method. The activities included in the Hands-On Hortscience curriculum were created to reinforce teaching the scientific method through the context of horticulture. The objectives included evaluating whether the students participating in the Hands-On Hortscience experimental group benefited in the areas of science literacy, data acquisition and analysis, and attitude toward horticulture, science, and school. Pre-tests were administered in both the experimental and control groups prior to the research activities and post-tests were administered after completion. The survey questionnaire included a biographical section and attitude survey. Significant increases in hortscience achievement were found from pre-test to post-test in both control and experimental study groups. The experimental treatment group had statistically higher achievement scores than the control group in the two areas tested: scientific method (p=0.0016) and horticulture plant nutrition (p=0.0004). In addition, the students participating in the Hands-On Hortscience activities had more positive attitudes toward horticulture, science, and school (p=0

    DNA barcoding relies on short and standardized gene regions to identify species. The agricultural and horticultural applications of barcoding such as for marketplace regulation and copyright protection remain poorly explored. This study examines the effectiveness of the standard plant barcode markers (matK and rbcL) for the identification of plant species in private and public nurseries in northern Egypt. These two markers were sequenced from 225 specimens of 161 species and 62 plant families of horticultural importance. The sequence recovery was similar for rbcL (96.4%) and matK (84%), but the number of specimens assigned correctly to the respective genera and species was lower for rbcL (75% and 29%) than matK (85% and 40%). The combination of rbcL and matK brought the number of correct generic and species assignments to 83.4% and 40%, respectively. Individually, the efficiency of both markers varied among different plant families; for example, all palm specimens (Arecaceae) were correctly assigned to species while only one individual of Asteraceae was correctly assigned to species. Further, barcodes reliably assigned ornamental horticultural and medicinal plants correctly to genus while they showed a lower or no success in assigning these plants to species and cultivars. For future, we recommend the combination of a complementary barcode (e.g. ITS or trnH-psbA) with rbcL + matK to increase the performance of taxa identification. By aiding species identification of horticultural crops and ornamental palms, the analysis of the barcode regions will have large impact on horticultural industry.

    This report is an analysis of the current state of electric transportation and its potential integration in the transportation system of the city of Toronto. In this document, electric vehicles include every mode of transport involving the use of energy drawn from the electricity grid, such as plug-in hybrid electric vehicles (PHEV), extended range electric vehicles (EREV), battery electric vehicles (BEV), grid connected transit vehicles and electrified locomotives. An overview of the movement of people and goods, including the consideration of patterns of commuting and modes of transportation, is provided in the first section of this document. It has been demonstrated that most of the trips taking place in the city correspond to the predicted operating range of many EVs. Section one also provides a description of the local electricity grid system serving Toronto neighbourhoods and of the sources and movements of air contaminants. It gives a evaluation of the state of EV technologies and analyzes the economic and social factors that have an impact on the public perceptions regarding these technologies. Current policies and programs designed to promote market adoption of EVs around the world are outlined in the conclusion of this section. A simulation work was performed through a collaborative work with Toronto Hydro Electric System Limited in order to analyze the consequences of different EV charging scenarios on the electricity grid system. The results of this simulation are described in section two of the report. The document also presents the outcomes of the workshop on the implementation of an electric mobility master plan held in Toronto in April, 2010. 176 refs.

    This is a study about emotion management among a category of healthcare professional - hospital chaplains - who have hardly been the subject of sociological research about emotions. The aim of the study was to understand how chaplains manage their work-related emotions in order to protect their mental health, whilst also providing spiritual care. Using in-depth, semi structured interviews, the author spoke with 21 chaplains from five faith traditions (Christianity, Islam, Judaism, Buddhism and modern paganism) in different Toronto (Canada) Hospitals to see how they manage their emotion, and what resources they rely on in order to protect their mental health. Data analysis was perfumed according to Sandelowski's method of qualitative description. The average age and work experience of the subjects interviewed in this study are 52 and 9.6 respectively. 11 chaplains worked part-time and 10 chaplains worked full-time. 18 respondents were women and the sample incudes 3 male chaplains only. The findings are discussed, among others, according to the following themes: work-life balance, self-reflexivity, methods of self-care, and chaplains' emotional make-up. Emotion management per se is not a problem. However, if chaplains fail to maintain a proper work-life balance, job pressure can be harmful. As a strategy, many chaplains work part-time. As a supportive means, an overwhelming number of chaplains regularly benefit from psychotherapy and/or spiritual guidance. None.

    A unique hybrid of remediation technologies was designed to deal with the problem of removing the gasoline and fuel-oil found in soils and groundwater as a result of spills or leakage at petroleum storage and dispensing facilities. Liquid petroleum hydrocarbons were found discharging into a creek in a residential and commercial neighborhood of Metropolitan Toronto. Numerous in-place soil and ground water remediation approaches were evaluated in the course of searching for a solution. A full-scale, transportable, in-situ bioslurping remediation unit was recommended. The unit was connected to 13 specially designed vertical bioslurping wells, and to a buried horizontal header network comprised of four separate zones that could be used to simultaneously extract and/or inject air and water flows. Cycling of various modes of operation was based on detailed monitoring and analysis, which allowed for optimal recovery and biological degradation of contaminants. After only four months of operation, over 4000 kg of petroleum hydrocarbon contaminants had been removed and treated, and all of the mobile liquid hydrocarbons at the water table had been removed. Treatment cost was estimated at $100 to $120 per tonne of contaminated soil, but assuming that the unit could be used at more than one site, the net treatment cost would decrease to $20 to $30 per tonne. 1 ill

    The Clean Air Partnership (CAP) was interested in scanning and prioritizing energy efficiency opportunities to reduce energy use and the associated greenhouse gas emissions in the greater Toronto area (GTA). A study was conducted to scope out the most promising program directions for the GTA should government funding become available to launch the initiative, based on the relative technical potential of energy efficiency (and some fuel substitution) measures in the targeted sectors. A report to the Ontario Power Authority (OPA) focused on the residential and institutional sectors. These included new and existing residential buildings, condominiums and single-family homes, with special detail provided on appliances and central air conditioning; as well as municipal, university, school, and hospital buildings, with special attention towards measures to make street and traffic signal lighting more energy efficient. This letter provided a summary of findings. Next steps were also presented. It was recommended that three market transformation initiatives be designed and implemented to realize the technical potential for reductions in peak electricity and carbon dioxide emissions reductions. These three programs were discussed with reference to the energy efficient lighting collaborative; a green loan program for new homes and condominiums; and a community residential CDM program. A market transformation framework was also presented. It addressed the five key steps in the movement of a product from the manufacturer to the end user, namely availability; awareness; accessibility; affordability; and acceptance. 1 tab., 3 figs.

    The Joint Health and Disease Management Program in the Toronto Central Local Health Integration Network (TC LHIN) is envisioned as a comprehensive model of care for patients with hip and knee arthritis. It includes access to assessment services, education, self-management programs and other treatment programs, including specialist care as needed. As the first phase of this program, the hospitals in TC LHIN implemented a Hip and Knee Replacement Program to focus on improving access and quality of care, coordinating services and measuring wait times for patients waiting for hip or knee replacement surgery. The program involves healthcare providers, consumers and constituent hospitals within TC LHIN. The approach used for this program involved a definition of governance structure, broad stakeholder engagement to design program elements and plans for implementation and communication to ensure sustainability. The program and approach were designed to provide a model that is transferrable in its elements or its entirety to other patient populations and programs. Success has been achieved in creating a single wait list, developing technology to support referral management and wait time reporting, contributing to significant reductions in waits for timely assessment and treatment, building human resource capacity and improving patient and referring physician satisfaction with coordination of care.

    2016-01-01

    Deep brain stimulation (DBS) is an established and effective treatment for Parkinson's disease (PD). After surgery, a number of extensive programming sessions are performed to define the most optimal stimulation parameters. Programming sessions mainly rely only on neurologist's experience. As a result, patients often undergo inconsistent and inefficient stimulation changes, as well as unnecessary visits. We reviewed the literature on initial and follow-up DBS programming procedures and integrated our current practice at Toronto Western Hospital (TWH) to develop standardized DBS programming protocols. We propose four algorithms including the initial programming and specific algorithms tailored to symptoms experienced by patients following DBS: speech disturbances, stimulation-induced dyskinesia and gait impairment. We conducted a literature search of PubMed from inception to July 2014 with the keywords "deep brain stimulation", "festination", "freezing", "initial programming", "Parkinson's disease", "postural instability", "speech disturbances", and "stimulation induced dyskinesia". Seventy papers were considered for this review. Based on the literature review and our experience at TWH, we refined four algorithms for: (1) the initial programming stage, and management of symptoms following DBS, particularly addressing (2) speech disturbances, (3) stimulation-induced dyskinesia, and (4) gait impairment. We propose four algorithms tailored to an individualized approach to managing symptoms associated with DBS and disease progression in patients with PD. We encourage established as well as new DBS centers to test the clinical usefulness of these algorithms in supplementing the current standards of care. Copyright © 2016 Elsevier Inc.

    The objective of the Low-level Tritium Research Facility for the University of Toronto Institute for Aerospace Studies (UTIAS) is to investigate tritium-material interactions and how they differ with respect to protium and deuterium. The tritium laboratory will also be employed to study tritium retention, tritium imaging, and the effect of tritium on diagnostic devices. This report is a preliminary design document of the UTIAS Low-Level Tritium Research Facility including the fundamentals of tritium, a description of the facility, tritium laboratory requirements and the safety analysis of the laboratory. The facility is designed to handle a total elemental tritium inventory of 10 Ci, though it will initially commence operation with 1 Ci and later increased to the maximum value. In the event of an instantaneous emission of the total tritium inventory within the laboratory, the working personnel would be exposed to an airborne tritium concentration less than the maximum permissible. Moreover, with all the safety features included in this design the likelihood of such an accident is very remote. Thus, the tritium laboratory design is intrinsically safe

    Full Text Available UNMIX, a sensor modeling routine from the U.S. Environmental Protection Agency (EPA, was used to model volatile organic compound (VOC receptors in four urban sites in Toronto, Ontario. VOC ambient concentration data acquired in 2000–2009 for 175 VOC species in four air quality monitoring stations were analyzed. UNMIX, by performing multiple modeling attempts upon varying VOC menus—while rejecting the results that were not reliable—allowed for discriminating sources by their most consistent chemical characteristics. The method assessed occurrences of VOCs in sources typical of the urban environment (traffic, evaporative emissions of fuels, banks of fugitive inert gases, industrial point sources (plastic-, polymer-, and metalworking manufactures, and in secondary sources (releases from water, sediments, and contaminated urban soil. The remote sensing and robust modeling used here produces chemical profiles of putative VOC sources that, if combined with known environmental fates of VOCs, can be used to assign physical sources’ shares of VOCs emissions into the atmosphere. This in turn provides a means of assessing the impact of environmental policies on one hand, and industrial activities on the other hand, on VOC air pollution.

    2006-01-01

    Details of a new cogeneration plant for Pearson International Airport were presented. The plant was installed to ensure that the airport will be self-sufficient with its own uninterrupted power supply, and will also provide steam for the airport's heating and cooling. The plant generated its first power onto the grid in August 2005. The 18,000 sq. foot cogeneration facility cost an estimated $140 million to build and is capable of supplying the airport with 117 MW of power. Power for the plant comes from 2 natural gas turbines, with an additional 33 MW generated by exhaust from the gas turbines passing through once-through steam generators producing steam for a third steam-driven generator. The remaining excess heat from the plant is used to heat and cool the airport buildings through a central utilities distribution system. Natural gas fueled cogeneration plants are considered to be clean energy, and it is anticipated that the plant will lessen the environmental impacts of the airport. Currently, the airport's peak electrical demand is approximately 38 MW of electricity, which is expected to peak at 65 to 70 MW in 2015. The surplus electricity produced at the cogeneration plant will be sold back into Ontario's power grid via the Clean Energy Supply contract. It was concluded that in addition to its environmental benefits, the plant will help to enhance electricity supply in the Greater Toronto Area (GTA)

    This acoustic assessment report was conducted to determine the potential noise impacts of a biogas cogeneration plant that will be located on a street in a primarily industrial area of Toronto, Ontario. The facility will be comprised of seven 1.416 MW biogas-fired reciprocating engine generators and a single flare. The report presented results obtained from noise level calculations and noise modelling studies of the on-site equipment at the planned facility. The cogeneration plant will utilize biogas produced in existing digesters to generate electricity and hot water. The biogas will be produced by anaerobic digestion from municipal sewage waste at an adjacent facility. It is expected that the facility will generate 9.912 MW of electricity from the generators. Heat resulting from the biogas combustion process is recovered from engine and exhaust flue gases by heat exchangers. The facility will operate continuously. Significant noise sources at the facility include generator exhaust gas stacks; air intake points; building ventilation fans; and roof-top heat dump radiators. Sound power levels determined for each of the noise sources were based upon worst-case operating scenarios. Results of the assessment indicated that the facility is in compliance with all Ministry of the Environment (MOE) requirements. 5 refs., 10 tabs., 4 figs.

    This paper describes the special considerations required to build a flood control dam in a metropolitan area that holds major city infrastructures such as power transmission towers, pipelines, sanitary sewers and graveyards. The paper refers to the G. Ross Lord Dam, a 20 m high earth fill flood control dam which was constructed in 1973 on the West Branch of the Don River in Toronto. It was built following recommendations after Hurricane Hazel caused widespread flooding and the death of 81 people in 1954. The dam includes a concrete chute spillway and stilling basin. The geotechnical design of the dam was described along with the dam structures and the methods used to flood proof the infrastructure. The dam has a sloping impervious core and an upstream blanket to reduce seepage. Seepage control is provided by a drainage blanket and a chimney drain. A main overflow spillway was constructed on the south abutment, and a low level outlet was constructed at the base of the dam to accommodate normal river flows through the dam. Most of the water level control during a flood event is provided by the main overflow spillway. Spillway slab anchor keys prevent down slope creep of the slabs. The dam, the spillway and the reservoir structure have performed well since construction. 6 refs., 10 figs.

    Full Text Available This article explores how the politics and economics of austerity has influenced collective bargaining between the CUPE Locals 79/416 and the city of Toronto. I explore the relationship between neoliberalism and workplace precarity, drawing attention to the importance of the municipal public sector to trade unionism and the political potential of urbanized Left-labour radicalism. Following this, I provide an overview of the repeated attempts by City Council to extract concessions from unionized workers with a focus on the concession-filled 2012 round of bargaining and its relationship to earlier rounds. In what follows I discuss the implications of austerity bargaining for Locals 79 and 416 members, drawing attention to the repercussions this may have for other public sector workers. To conclude, I propose an alternative political strategy for municipal public sector unions, stressing the importance of a radicalized labour approach. It is my contention that this requires the development of both alternative policies and an alternative politics rooted in demands for workplace democracy and social justice.

    Full Text Available This research presents a Geographic Information Systems (GIS and spatial analysis approach based on the global spatial autocorrelation of road traffic injuries for identifying spatial patterns. A locational spatial autocorrelation was also used for identifying traffic injury at spatial level. Data for this research study were acquired from Canadian Institute for Health Information (CIHI based on 2004 and 2011. Moran’s I statistics were used to examine spatial patterns of road traffic injuries in the Greater Toronto Area (GTA. An assessment of Getis-Ord Gi* statistic was followed as to identify hot spots and cold spots within the study area. The results revealed that Peel and Durham have the highest collision rate for other motor vehicle with motor vehicle. Geographic weighted regression (GWR technique was conducted to test the relationships between the dependent variable, number of road traffic injury incidents and independent variables such as number of seniors, low education, unemployed, vulnerable groups, people smoking and drinking, urban density and average median income. The result of this model suggested that number of seniors and low education have a very strong correlation with the number of road traffic injury incidents.

    The municipalities of the Greater Toronto Area (GTA) will be implementing initiatives in solid waste management, in view of the fact that current landfill capacity is nearly exhausted. A consolidation of information is provided on the solid waste management plans, programs, and facilities within the GTA. In response to environmental concerns coupled with difficulties encountered in developing new solid waste disposal facilities, waste reduction, reuse, and recycling efforts are developing rapidly. Some of the measures currently implemented and under investigation include: curbside recycling programs for newspapers, glass, metal, and plastic containers; expanding recycling efforts to apartment buildings; expanding the kinds of materials collected through the curbside programs; improving recycling services in rural areas; public education and promotional programs; promotion of home composting; household hazardous waste programs; recovery of cardboard from commercial and industrial sources, coupled with bans on cardboard at landfills; recovery of selected waste building materials such as wood and drywall, coupled with bans on these materials at landfills; recovery of paper from office buildings; and programs to assist industries in waste reduction, reuse, and recycling. The solid wastes generated in the GTA are managed in a number of facilities including recycling centers, transfer stations, and landfill sites. A 410 tonne/day energy-from-waste facility has recently been approved for Peel Region and is planned to be constructed in the coming year. 21 refs., 1 fig., 14 tabs.

    Toronto Hydro-Electric System Limited (THESL) has long been devoted to the enhancement of its asset management program. In 2006, Kinectrics Incorporated (Kinectrics) performed a full asset condition assessment (ACA) for important distribution assets. Subsequently, THESL made efforts to follow the recommendations given by the 2006 ACA and to enhance the quality of its asset condition data. THESL also created an application that measures the health indices of assets based on current and best available inspection data. In 2009, THESL performed a new ACA with this health index calculator. Kinectrics was requested to evaluate the improvement achieved by THESL between 2006 and 2009, and to compare the results obtained from the two ACA performed. An examination of the changes and ACA results between 2009 and 2010 has been conducted by Kinectrics. The Kinectrics findings were reported into the 2010 asset condition assessment audit report. The Health Index (HI) formulation and the results obtained between 2009 and 2010 were examined for twenty-one asset categories. The health index formulation including condition parameters, condition parameter weights and condition criteria, the granularity within the asset category, the percentage of the population presenting sufficient condition data and the health index classification distribution were compared for each one of the asset categories between 2009 and 2010. This report provides recommendations to facilitate future improvements.

    This study investigated associations between long-term exposure to ambient volatile organic compounds (VOCs) and mortality. 58,760 Toronto residents (≥35 years of age) were selected from tax filings and followed from 1982 to 2004. Death information was extracted using record linkage to national mortality data. Land-use regression surfaces for benzene, n-hexane, and total hydrocarbons were generated from sampling campaigns in 2002 and 2004 and assigned to residential addresses in 1982. Cox regression was used to estimate relationships between each VOC and non-accidental, cardiovascular, and cancer mortality. Positive associations were observed for each VOC. In multi-pollutant models the benzene and total hydrocarbon signals were strongest for cancer. The hazard ratio for cancer that corresponded to an increase in the interquartile range of benzene (0.13 μg/m(3)) was 1.06 (95% CI = 1.02-1.11). Our findings suggest ambient concentrations of VOCs were associated with cancer mortality, and that these exposures did not confound our previously reported associations between NO2 and cardiovascular mortality.

    Homelessness has been identified as an important risk factor for suicide death, but there is limited research characterising homeless people who die by suicide. The goal of this study is to identify personal, clinical, and suicide method-related factors that distinguish homeless and precariously housed people who die from suicide from those who are not homeless at the time of suicide. Coroner records were reviewed for all suicide deaths in Toronto from 1998 to 2012. Data abstracted included housing status as well as other demographics, clinical variables such as the presence of mental illness, and suicide method. Of 3319 suicide deaths, 60 (1.8%) were homeless and 230 (6.9%) were precariously housed. Homeless and precariously housed people were each younger than nonhomeless people ( P suicide note. Homeless people and precariously housed were more likely to have died by fall/jump than nonhomeless people (62%, 57%, and 29%, respectively). Homeless and precariously housed people are overrepresented among suicide deaths in a large urban center and differ demographically, clinically, and in their suicide method from nonhomeless people who die by suicide. Targeted suicide prevention strategies should aim to address factors specific to homeless people.

    This work aimed to demonstrate the feasibility of nitrification applied to the treatment of leachates formed during composting of cattle and pig manure in order to promote their further use as liquid fertilizer in horticulture. Nitrification trials were successfully conducted in summer and winter seasons under Mediterranean climate conditions. Subsequently, effect of using the nitrified effluents as nutritive solution in the fertigation of lettuce (Lactuca sativa L.) was assessed in terms of productivity and nutrient uptake. Similar productivities were obtained when using the nitrified effluents and a standard nutritive solution. However, results also evidenced high nutrient uptake, which indicates that dosage should be adjusted to culture requirements. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Geothermal energy is too expensive to serve as energy supply for most horticultural entrepreneurs. Therefore, research has been carried out into options to use heat from more shallow layers (shallow geothermal energy). Unlike shallow geothermal energy deep geothermal energy can be applied on a smaller scale, possibly also for individual growers. It can be applied in combination with an existing heating system, but with a more sustainable outcome. Because drilling is done in shallow layers, drilling costs and financial risks are lower [Dutch] Geothermie is voor de meeste tuinbouwondernemers teduur om als energievoorziening te dienen. Daarom is onderzoek gedaan naar mogelijkheden om warmte te gebruiken uit ondiepere lagen (ondiepe geothermie). In tegenstelling tot diepe geothermie is ondiepe geothermie op kleinere schaal toepasbaar, mogelijk ook voor individuele kwekers. Het kan in combinatie met de bestaande verwarmingsinstallatie worden ingezet maar met een duurzamer resultaat. Omdat ondieper wordt geboord zijn de boorkosten en de financiele risico's lager.

    Ozone flux-response relationships were derived for lettuce, employing a multiplicative approach to model the manner in which stomatal conductance is influenced by key environmental variables, using a dataset collected during field experimentation in Crete and yield-response relationships derived from parallel open-top chamber experiments. Regional agronomic practices were adopted throughout. Computed versus measured data revealed that the derived model explained 51% (P -2 s -1 . Regressions employing very low or zero flux thresholds resulted in the strongest yield-flux relationships (explaining ∼80% (P < 0.05) of the variation in the dataset). - Establishment of ozone flux-yield relationships for a commercially-important horticultural crop grown widely in the Mediterranean

    Full Text Available This paper reviews the plant viruses and virus vectors that have been detected in agricultural and horticultural crop plants and some weeds in Finland. The historical and current importance of virus diseases and the methods used for controlling them in cereals, potato, berry plants, fruit trees, ornamental plants and vegetables are discussed. Plant viruses have been intensely studied in Finland over 40 years. Up to date, 44 plant virus species have been detected, and many tentatively identified virus-es are also reported. Control of many virus diseases has been significantly improved. This has been achieved mainly through changes in cropping systems, production of healthy seed potatoes and healthy stocks of berry plants, fruit trees and ornamental plants in the institutes set up for such production, and improved hygiene. At the present, barley yellow dwarf luteovirus, potato Y potyvirus and potato mop-top furovirus are considred to be economically the most harmful plant viruses in Finland.

    Data collected mainly from an inventory of waste heat projects in the EEC prepared by Potentiel Energie of Paris covers 46 projects approximately half of which are fish farms and half horticultural projects mainly in the form of greenhouses. About a half of the projects are run on a commercial basis while the other half are Research and Development (R and D) or demonstrations. At least 18 species of fish and 18 species of plant are produced at the various projects but eels and potted plants are grown at more of the commercially orientated projects than any other produce. There has been a significant increase in the number of commercially run projects during the past 10-15 years and this trend is likely to continue in view of the considerable savings that can be made on fuel. The size and number of commercial projects in the UK compares favourably with those in other EEC countries. (author)

    Non-coding RNAs (ncRNAs), that is, RNAs not translated into proteins, are crucial regulators of a variety of biological processes in plants. While protein-encoding genes have been relatively well-annotated in sequenced genomes, accounting for a small portion of the genome space in plants, the universe of plant ncRNAs is rapidly expanding. Recent advances in experimental and computational technologies have generated a great momentum for discovery and functional characterization of ncRNAs. Here we summarize the classification and known biological functions of plant ncRNAs, review the application of next-generation sequencing (NGS) technology and ribosome profiling technology to ncRNA discovery in horticultural plants and discuss the application of new technologies, especially the new genome-editing tool clustered regularly interspaced short palindromic repeat (CRISPR)/CRISPR-associated protein 9 (Cas9) systems, to functional characterization of plant ncRNAs.

    2014-04-01

    Full Text Available The active modified atmosphere packaging (active MAP system , which provides interactive postharvest control , using ethanol vapour controlled release, is one of the current interests in the development of active packaging for horticultural products. A number of published research work have discussed the relationship between the effectiveness of ethanol vapour and its concentration in the package headspace, including its effect on postharvest decay and physiological controls. This is of importance because a controlled release system should release and maintain ethanol vapour at effective concentrations during the desired storage period. A balance among the mass transfer processes of ethanol vapour in the package results in ethanol vapour accumulation in the package headspace. Key factors affecting these processes include ethanol loading, packaging material, packaged product and storage environment (temperature and relative h umidity. This article reviews their influences and discusses future work required to better understand their influences on ethanol vapour release and accumulations in active MAP.

    This report discusses the use of accelerated stress testing (AST) to provide insights into the long-term behavior of commercial products utilizing different types of mid-power LEDs (MP-LEDs) integrated into the same LED module. Test results are presented from two commercial lamps intended for use in horticulture applications and one tunable-white LED module intended for use in educational and office lighting applications. Each of these products is designed to provide a custom spectrum for their targeted applications and each achieves this goal in different ways. Consequently, a comparison of the long-term stability of these devices will provide insights regarding approaches that could be used to possibly lengthen the lifetime of SSL products.

    Frail nursing home residents face multiple health challenges as a result of their frail status. The aim of this study was to examine the effects of HT on the psychosocial well-being of frail and prefrail nursing home residents. Randomized controlled trial. Nursing homes. One hundred eleven participants were randomly allocated into the intervention [horticultural therapy (HT)] and control (social activities) conditions. HT group participants attended a weekly 60-minute session for 8 consecutive weeks. Control group activities were social in nature, without any horticulture components. The outcome measures include happiness, depressive symptoms, self-efficacy, well-being, social network, and social engagement. The time points of measurement were at baseline (T 0 ), immediately postintervention (T 1 ), and 12 weeks postintervention (T 2 ). A modified intention-to-treat approach was adopted. A multivariate general estimating equation was used to analyze the data. Forty-six and 50 participants received at least 1 session of the intervention and control condition protocol, respectively. A significant interaction effect between group and time was observed only on the happiness scale (β = 1.457, P = .036), but not on other outcome variables. In a follow-up cluster analysis of those who received HT, a greater effect on subjective happiness (mean difference = 6.23, P < .001) was observed for participants who were happier at baseline. HT was found to be effective in promoting subjective happiness for frail and prefrail nursing home residents. Its favorable effect suggests that HT should be used to promote the psychosocial well-being of those who are frail. Copyright © 2018 AMDA – The Society for Post-Acute and Long-Term Care Medicine.

    Natural control by predators and parasitoids provides an important and often unnoticed ecosystem service to agricultural landscapes by reducing pest populations in crops. The current model of horticultural intensification in south-eastern Spain produces high yields but has also resulted in a landscape almost completely covered by plastic. Promoting natural areas among greenhouses could enhance biodiversity, by being beneficial insects, and reduce pest pressure outdoors. The first step is to ascertain how pests and their natural enemies (NEs) use Mediterranean vegetation for selecting the best plants for pest suppression outdoors. The abundance of the two major horticultural pests, the tobacco whitefly, Bemisia tabaci, and the western flower thrips, Frankliniella occidentalis, together with their NEs, were assayed in 22 flowering perennial plants, which were newly planted in an experimental field surrounded by greenhouses. Eight plant species were identified as the most critical species for sustaining pest populations outdoors. A set of five plant species supported a medium level of pests, and another set of ten plant species supported the lowest level of both pests. Tobacco whitefly occurred in a few plants species, whereas western flower thrips occurred on almost all the plant species studied, and was favoured by the presence of flowers in perennial plants. The results suggest that plant diversity may provide relatively few acceptable host plants for tobacco whitefly than for western flower thrips. NEs were generally collected in plants that also supported abundance of pests, indicating that host/prey availability, more than food resources from flowers, was a stronger predictor of NE abundance in perennial plants. Field trials using the plants with the lowest host acceptance by pests are needed in order to ascertain whether pest abundance outdoors is reduced.

    Modern humans may have gracile skeletons due to low physical activity levels and mechanical loading. Tests using pre-historic skeletons are limited by the inability to assess behavior directly, while modern industrialized societies possess few socio-ecological features typical of human evolutionary history. Among Tsimane forager-horticulturalists, we test whether greater activity levels and, thus, increased loading earlier in life are associated with greater later-life bone status and diminished age-related bone loss. We used quantitative ultrasonography to assess radial and tibial status among adults aged 20+ years (mean ± SD age = 49 ± 15; 52% female). We conducted systematic behavioral observations to assess earlier-life activity patterns (mean time lag between behavioural observation and ultrasound = 12 years). For a subset of participants, physical activity was again measured later in life, via accelerometry, to determine whether earlier-life time use is associated with later-life activity levels. Anthropometric and demographic data were collected during medical exams. Structural decline with age is reduced for the tibia (female: -0.25 SDs/decade; male: 0.05 SDs/decade) versus radius (female: -0.56 SDs/decade; male: -0.20 SDs/decade), which is expected if greater loading mitigates bone loss. Time allocation to horticulture, but not hunting, positively predicts later-life radial status (β Horticulture  = 0.48, p = 0.01), whereas tibial status is not significantly predicted by subsistence or sedentary leisure participation. Patterns of activity- and age-related change in bone status indicate localized osteogenic responses to loading, and are generally consistent with the logic of bone functional adaptation. Nonmechanical factors related to subsistence lifestyle moderate the association between activity patterns and bone structure. © 2017 Wiley Periodicals, Inc.

  5. Horticultural markets promote alien species invasions: an Estonian case study of herbaceous perennials

    Full Text Available Gardening is a popular pastime, but commercial horticulture is responsible for the introduction of alien species and contributes to invasions in a variety of ways. Although an extensive international literature is available on plant invasions, it is still important at the national level to examine the influence of local factors. Accordingly, 17 nurseries in Estonia that cultivated and sold perennial alien species were selected, and a list of species and prices was compiled. The relationships between species status, and factors such as their abundance in the wild were examined statistically. A qualitative list of the nationally problematic species among herbaceous perennials was also completed. A total of 880 taxa were recorded, of which 10.3% were native and 89.7% alien. In all, 87.3% of the alien species were still confined to cultivated areas. The ecological and socio-economic characteristics of the taxa were described, and lists of the families of casual, naturalised and invasive aliens were provided. Both native and increasing wild alien species have a very similar profile on the market. Alien species that are less expensive, widely available and have more cultivars per species on the market are also more likely to escape. The invasive status and abundance of escaped aliens in an area increases with residence time. In general, socio-economic factors create new and reflect previous propagule pressures from commercial horticulture, which continuously increase the likelihood of alien species surviving and invading new areas. Our findings suggest that these national socio-economic market-related factors explain much of the invasiveness of various perennial ornamental species, and therefore regional and national authorities urgently need to regulate and control the ornamental plant trade to diminish the risk of new invasions.

  6. Towards Regenerated and Productive Vacant Areas through Urban Horticulture: Lessons from Bologna, Italy

    Full Text Available In recent years, urban agriculture has been asserting its relevance as part of a vibrant and diverse food system due to its small scale, its focus on nutrition, its contribution to food security, its employment opportunities, and its role in community building and social mobility. Urban agriculture may also be a tool to re-appropriate a range of abandoned or unused irregular spaces within the city, including flowerbeds, roundabouts, terraces, balconies and rooftops. Consistently, all spaces that present a lack of identity may be converted to urban agriculture areas and, more specifically, to urban horticulture as a way to strengthen resilience and sustainability. The goal of this paper is to analyse current practices in the requalification of vacant areas as urban gardens with the aim of building communities and improving landscapes and life quality. To do so, the city of Bologna (Italy was used as a case study. Four types of vacant areas were identified as places for implementing urban gardens: flowerbeds along streets and squares, balconies and rooftops, abandoned buildings and abandoned neighbourhoods. Six case studies representing this variety of vacant areas were identified and evaluated by collecting primary data (i.e., field work, participant observations and interviews and performing a SWOT analysis. For most cases, urban horticulture improved the image and quality of the areas as well as bringing numerous social benefits in terms of life quality, food access and social interaction among participants. Strong differences in some aspects were found between top-down and bottom-up initiatives, being the later preferable for the engagement of citizens. Policy-making might focus on participatory and transparent planning, long-term actions, food safety and economic development.

    2001-01-01

    In 2000, the Toronto Atmospheric Fund (TAF) embarked on an initiative to quantify the potential benefits of Heat Island Reduction (HIR) strategies (shade trees, reflective roofs and pavements) in reducing cooling energy use in buildings, lowering the ambient air temperature and improve air quality. This report summarizes the efforts of Lawrence Berkeley National Laboratory (LBNL) to assess the impacts of HIR measures on building cooling- and heating-energy use. We discuss our efforts to calculate annual energy savings and peak-power avoidance of HIR strategies in the building sector of the Greater Toronto Area. The analysis is focused on three major building types that offer most saving potentials: residence, office and retail store. Using an hourly building energy simulation model, we quantify the energy saving potentials of (1) using cool roofs on individual buildings[direct effect], (2) planting deciduous shade trees near south and west walls of building[direct effect], (3) planting coniferous wind-shielding vegetation near building[direct effect], (4) ambient cooling by a large-scale program of urban reforestation with reflective building roofs and pavements[indirect effect], (5) and the combined direct and indirect effects. Results show potential annual energy savings of over$11M (with uniform residential and commercial electricity and gas prices of$0.084/kWh and$5.54/GJ) could be realized by ratepayers from the combined direct and indirect effects of HIR strategies. Of that total, about 88 percent was from the direct impact roughly divided equally among reflective roofs, shade trees and wind-shielding, and the remainder (12 percent) from the indirect impact of the cooler ambient air temperature. The residential sector accounts for over half (59 percent) of the total, offices 13 percent and retail stores 28 percent. Savings from cool roofs were about 20 percent, shade trees 30 percent, wind shielding of tree 37 percent, and indirect effect 12 percent. These

    Ambient air pollution is a major health risk globally. To reduce adverse health effects on days when air pollution is high, government agencies worldwide have implemented air quality alert programmes. Despite their widespread use, little is known about whether these programmes produce any observable public-health benefits. We assessed the effectiveness of such programmes using a quasi-experimental approach. We assembled a population-based cohort comprising all individuals who resided in the city of Toronto (Ontario, Canada) from 2003 to 2012 (about 2·6 million people). We ascertained seven health outcomes known to be affected by short-term elevation of air pollution, using provincial health administrative databases. These health outcomes were cardiovascular-related mortality, respiratory-related mortality, and hospital admissions or emergency-department visits for acute myocardial infarction, heart failure, stroke, asthma, and chronic obstructive pulmonary disease (COPD). We applied a regression discontinuity design to assess the effectiveness of an intervention (ie, the air quality alert programme). To quantify the effect of the air quality alert programme, we estimated for each outcome both the absolute rate difference and the rate ratio attributable to programme eligibility (by intention-to-treat analysis) and the alerts themselves (by two-stage regression approach), respectively. Between Jan 1, 2003, and Dec 31, 2012, on average between three and 27 daily cardiovascular or respiratory events were reported in Toronto (depending on the outcome). Alert announcements reduced asthma-related emergency-department visits by 4·73 cases per 1 000 000 people per day (95% CI 0·55-9·38), or in relative terms by 25% (95% CI 1-47). Programme eligibility also led to 2·05 (95% CI 0·07-4·00) fewer daily emergency-department visits for asthma. We did not detect a significant reduction in any other health outcome as a result of alert announcements or programme

    (electricity and natural gas), and the demand for energy. Climate factors considered include changes in the mean, but more importantly variability in temperatures and changes in extreme weather events. This part of the discussion draws upon extensive research in the Toronto-Niagara Region, which has been supported through the Federal Interdepartmental Panel on Energy Research and Development (PERD). Emphasis is placed on identifying what aspects of current climate have had the greatest impact on the energy sector, and the adaptation options that will be necessary to reduce future vulnerability in face of inevitable climate variability and change. In section three, the emphasis shifts towards actions to reduce GHG plus related emissions, within the context of environmental and health benefits. The co-benefits of reducing GHG plus related emissions includes the implications for ecosystems and biodiversity, environmental health (managed (forestry) and unmanaged (agriculture) systems), social welfare and human health. This discussion is based on research conducted on co-benefits as part of the multi-stakeholder process to develop a national strategy on climate change. The paper concludes by providing a preliminary assessment of the various mitigation options currently being proposed to help reach emission targets set out in the Kyoto Protocol, as they apply to the Toronto-Niagara Region. The assessment, which will be undertaken in greater depth as part of Phases III through V of the PERD supported project, considers the vulnerability of an altered energy system to climate change impacts, and the potential co-benefits for environment and health This includes changes brought about by fossil fuel switching, the inter-provincial transmission of electricity, alternative technologies, and energy efficiency, amongst other mitigation actions.

    To describe the Toronto Obsessive-Compulsive Scale (TOCS), a novel 21-item parent- or self-report questionnaire that covers wide variation in obsessive-compulsive (OC) traits, and to evaluate its psychometric properties in a community-based pediatric sample. The TOCS was completed for 16,718 children and adolescents between the ages of 6 and 17 years in a community setting. Internal consistency, convergent validity with the Obsessive-Compulsive Scale of the Child Behaviour Checklist (CBCL-OCS), divergent validity with the Strengths and Weaknesses of ADHD (Attention-Deficit/Hyperactivity Disorder) Symptoms and Normal Behaviour Rating Scale (SWAN), interrater reliability, as well as sensitivity and specificity of the TOCS were assessed. The internal consistency of the 21 TOCS items was excellent (Cronbach's α = 0.94). TOCS was moderately correlated with the CBCL-OCS (Spearman correlation = 0.51) and poorly correlated with the SWAN (Pearson correlation = 0.02). Sensitivity and specificity analyses indicated that a TOCS total score of greater than 0 successfully discriminated community-reported obsessive-compulsive disorder (OCD) cases from noncases. OC traits were continuously distributed both at the total score and dimensional level in our pediatric community sample. TOCS is a multidimensional measure of OC traits in children and adolescents with sound psychometric properties. TOCS reveals that OC traits are common and continuously distributed in a community sample. TOCS may be a useful measure for studies of the characteristics and etiology of OC traits. Copyright © 2016.

    Deep brain stimulation (DBS) is an effective treatment for essential tremor (ET) and dystonia. After surgery, a number of extensive programming sessions are performed, mainly relying on neurologist's personal experience as no programming guidelines have been provided so far, with the exception of recommendations provided by groups of experts. Finally, fewer information is available for the management of DBS in ET and dystonia compared with Parkinson's disease. Our aim is to review the literature on initial and follow-up DBS programming procedures for ET and dystonia and integrate the results with our current practice at Toronto Western Hospital (TWH) to develop standardized DBS programming protocols. We conducted a literature search of PubMed from inception to July 2014 with the keywords "balance", "bradykinesia", "deep brain stimulation", "dysarthria", "dystonia", "gait disturbances", "initial programming", "loss of benefit", "micrographia", "speech", "speech difficulties" and "tremor". Seventy-six papers were considered for this review. Based on the literature review and our experience at TWH, we refined three algorithms for management of ET, including: (1) initial programming, (2) management of balance and speech issues and (3) loss of stimulation benefit. We also depicted algorithms for the management of dystonia, including: (1) initial programming and (2) management of stimulation-induced hypokinesia (shuffling gait, micrographia and speech impairment). We propose five algorithms tailored to an individualized approach to managing ET and dystonia patients with DBS. We encourage the application of these algorithms to supplement current standards of care in established as well as new DBS centers to test the clinical usefulness of these algorithms in supplementing the current standards of care.

    Atmospheric gaseous elemental mercury [GEM] at 1.8, 4, and 59 m above ground, in parking lots, and in indoor and outdoor air was measured in Toronto City, Canada from May 2008-July 2009. The average GEM value at 1.8 m was 1.89 ± 0.62 ng m -3 . The GEM values increased with elevation. The average GEM in underground parking lots ranged from 1.37 to 7.86 ng m -3 and was higher than those observed from the surface parking lots. The GEM in the indoor air ranged from 1.21 to 28.50 ng m -3 , was higher in the laboratories than in the offices, and was much higher than that in the outdoor air. All these indicate that buildings serve as sources of mercury to the urban atmosphere. More studies are needed to estimate the contribution of urban areas to the atmospheric mercury budget and the impact of indoor air on outdoor air quality and human health. - Highlights: → Buildings served as mercury sources to urban atmosphere. → Atmospheric mercury level increased with increasing height in the street canyon. → Emission from vehicles and ground surfaces was not the major sources of Hg to urban air. → Mercury levels were higher in indoor than outdoor air and in laboratories than in offices. → Mercury levels were higher in the outdoor air near building walls. - Buildings serve as sources of gaseous elemental mercury and research is needed to quantify the emission and to assess the impact of indoor air on outdoor air quality and human health.

    We sought to document pathways between under/unemployment and health among racialized immigrant women in Toronto while exploring the ways in which gender, class, migration and racialization, as interlocking systems of social relations, structure these relationships. We conducted 30 interviews with racialized immigrant women who were struggling to get stable employment that matched their education and/or experience. Participants were recruited through flyers, partner agencies and peer researcher networks. Most interviews (21) were conducted in a language other than English. Interviews were transcribed, translated as appropriate and analyzed using NVivo software. The project followed a community-based participatory action research model. Under/unemployment negatively impacted the physical and mental health of participants and their families. It did so directly, for example through social isolation, as well as indirectly through representation in poor quality jobs. Under/unemployment additionally led to the intensification of job search strategies and of the household/caregiving workload which also negatively impacted health. Health problems, in turn, contributed to pushing participants into long-term substandard employment trajectories. Participants' experiences were heavily structured by their social location as low income racialized immigrant women. Our study provides needed qualitative evidence on the gendered and racialized dimensions of under/unemployment, and adverse health impacts resulting from this. Drawing on intersectional analysis, we unpack the role that social location plays in creating highly uneven patterns of under/unemployment and negative health pathways for racialized immigrant women. We discuss equity informed strategies to help racialized immigrant women overcome barriers to stable work that match their education and/or experience.

    Assessing recreational water quality requires a fundamental understanding of metal-microbial interactions and the key biogeochemical processes occurring in urban public beaches. Metals play an important role in the distribution and virulence (e.g. resistance) of microorganisms in water systems. In turn, microorganisms have a significant influence on metal cycling, thus affecting metal mobility, bioavailability and toxicity in the aquatic environment. Bacteria adhere to floc, small suspended mineral-bacterial aggregates, in aquatic systems resulting in high-density floc-associated bacterial biofilm communities. These nanoparticulate bacterial microhabitats are important environmental sinks for metals and potential reservoirs for antibiotic resistant and pathogenic bacteria. The objectives of this study are to identify and quantify (1) metal distributions among suspended floc, bed sediment and water-column aqueous compartments (2) important biogeochemical processes influencing metal cycling and (3) linkages between floc metals and the occurrence of floc associated antibiotic resistant bacteria and pathogens across a series of variably contaminated aquatic systems. Results of this project will provide new diagnostic indicators of pathogens in recreational water systems and aid in the development of public health policies to improve water quality and reduce water borne infectious disease. Here, results will be presented assessing the metal and microbial community dynamics in samples collected from Toronto's Sunnyside Beach (May 13 and August 20), an urban public beach on Lake Ontario. Water column, floc and bed sediments near and offshore were analyzed for physico-chemical characteristics and metal concentrations. Floc were imaged using DAPI and FISH to assess microbial community structure. Results to date, characterizing the linkages amongst bacteria, metal contaminant concentrations and sediment partitioning and system physico-chemical conditions will be discussed.

    2016-10-01

    The study contributes to literature on bicycle safety by building on the traditional count regression models to investigate factors affecting bicycle crashes at the Traffic Analysis Zone (TAZ) level. TAZ is a traffic related geographic entity which is most frequently used as spatial unit for macroscopic crash risk analysis. In conventional count models, the impact of exogenous factors is restricted to be the same across the entire region. However, it is possible that the influence of exogenous factors might vary across different TAZs. To accommodate for the potential variation in the impact of exogenous factors we formulate latent segmentation based count models. Specifically, we formulate and estimate latent segmentation based Poisson (LP) and latent segmentation based Negative Binomial (LNB) models to study bicycle crash counts. In our latent segmentation approach, we allow for more than two segments and also consider a large set of variables in segmentation and segment specific models. The formulated models are estimated using bicycle-motor vehicle crash data from the Island of Montreal and City of Toronto for the years 2006 through 2010. The TAZ level variables considered in our analysis include accessibility measures, exposure measures, sociodemographic characteristics, socioeconomic characteristics, road network characteristics and built environment. A policy analysis is also conducted to illustrate the applicability of the proposed model for planning purposes. This macro-level research would assist decision makers, transportation officials and community planners to make informed decisions to proactively improve bicycle safety - a prerequisite to promoting a culture of active transportation.

    2000-06-23

    New federal and provincial initiatives to improve air quality were announced at the recent first-ever Toronto Smog Summit. An initial one million dollars have been pledged by the federal Minister of the Environment to support a framework for extending daily air quality forecasting across Canada, to begin within the next year. The funding will be used to increase the information base of existing air quality advisory programs in Ontario, and to create a daily air quality index immediately in other areas of the country most affected by smog. Existing air quality assessment programs will be expanded to include air quality models incorporating measurement and reporting of particulate matter levels. A second federal initiative also announced at the is meeting will be a corporate smog action plan, led by the Ontario regional offices of the federal departments of the Environment, Health Canada, and Public Works and Government Services. This program will include rapid response by federal government departments during Smog Alerts Days and measures to reduce the federal government's contribution to causing smog through encouragement of low or no emission options for employees, educational programs on best practices at home and at the office, reduction of employee travel through flextime and telecommuting, conversion of government vehicles to natural gas and other alternatives, and retrofitting government buildings for greater energy and water efficiency. A federal commitment of at least $200,000 was also announced by the Minister of Transport to support six sustainable transportation projects. The provincial Minister of the Environment announced the membership of the province's Anti-Smog Action Plan, which involves some 50 partners from industry associations, companies, government agencies and non-government organizations to help Ontario to meet its commitment to reduces nitrogen oxides and volatile organic compounds emissions by 45 per cent by 2015.

  20. Using nudges to reduce waste? The case of Toronto's plastic bag levy.

    Rivers, Nicholas; Shenstone-Harris, Sarah; Young, Nathan

    2017-03-01

    The overuse of disposable plastic bags is a major environmental problem across the globe. In recent years, numerous jurisdictions have sought to curb disposable bag use by implementing a levy or fee at the point of purchase. These levies are typically small and symbolic (around $0.05 per bag), but serve as a highly-visible and continuous reminder to consumers. As such, they are consistent with nudging policies that seek to encourage broad changes in behaviour through small, non-coercive measures that influence people's thinking about an issue. While existing empirical evidence suggests that nudges are highly effective in reducing disposable bag use, we argue that many of these studies are flawed because they lack adequate temporal and geographic controls. We use longitudinal data from four waves of a major Canadian survey to analyze the effect of a disposable bag levy in the City of Toronto. Controlling for demographics and changes in social norms over time, we find that the levy increased the use of reusable shopping bags by 3.4 percentage points. Moreover, we find that the impact of the policy was highly variable across behavioural and demographic groups. The levy was highly effective in encouraging people who already used reusable bags to use them more frequently, while having no effect on infrequent users. We also find that the effects are limited to households with high socio-economic status (as measured by income, educational attainment, and housing situation). This suggests important limitations for nudging policy more generally, as people with lower socio-economic status appear to have been unaffected by this behavioural prompt.

    Bullying has been identified as a potential contributing factor in youth suicide. This issue has been highlighted in recent widely publicized media reports, worldwide, in which deceased youth were bullied. We report on an observational study conducted to determine the frequency of bullying as a contributing factor to youth suicide. Coroner records were reviewed for all suicide deaths in youth aged between 10 and 19 in the city of Toronto from 1998 to 2011. Data abstracted were recent stressors (including bullying), clinical variables, such as the presence of mental illness, demographics, and methods of suicide. Ninety-four youth suicides were included in the study. The mean age was 16.8 years, and 70.2% were male. Bullying was present in 6 deaths (6.4%), and there were no deaths where online or cyberbullying was detected. Bullying was the only identified contributing factor in fewer than 5 deaths. The most common stressors identified were conflict with parents (21.3%), romantic partner problems (17.0%), academic problems (10.6%), and criminal and (or) legal problems (10.6%). Any stressor or mental and (or) physical illness was detected in 78.7% of cases. Depression was detected in 40.4% of cases. Our study highlights the need to view suicide in youth as arising from a complex interplay of various biological, psychological, and social factors of which bullying is only one. It challenges simple cause-and-effect models that may suggest that suicide arises from anyone factor, such as bullying.

  2. Sources, emissions, and fate of polybrominated diphenyl ethers and polychlorinated biphenyls indoors in Toronto, Canada.

    2011-04-15

    Indoor air concentrations of polybrominated diphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) measured in 20 locations in Toronto ranged 0.008-16 ng·m(-3) (median 0.071 ng·m(-3)) and 0.8-130.5 ng·m(-3) (median 8.5 ng·m(-3)), respectively. PBDE and PCB air concentrations in homes tended to be lower than that in offices. Principal component analysis of congener profiles suggested that electrical equipment was the main source of PBDEs in locations with higher concentrations, whereas PUF furniture and carpets were likely sources to locations with lower concentrations. PCB profiles in indoor air were similar to Aroclors 1248, 1232, and 1242 and some exterior building sealant profiles. Individual PBDE and PCB congener concentrations in air were positively correlated with colocated dust concentrations, but total PBDE and total PCB concentrations in these two media were not correlated. Equilibrium partitioning between air and dust was further examined using log-transformed dust/air concentration ratios for which lower brominated PBDEs and all PCBs were correlated with K(OA). This was not the case for higher brominated BDEs for which the measured ratios fell below those based on K(OA) suggesting the air-dust partitioning process could be kinetically limited. Total emissions of PBDEs and PCBs to one intensively studied office were estimated at 87-550 ng·h(-1) and 280-5870 ng·h(-1), respectively, using the Multimedia Indoor Model of Zhang et al. Depending on the air exchange rate, up to 90% of total losses from the office could be to outdoors by means of ventilation. These results support the hypotheses that dominant sources of PBDEs differ according to location and that indoor concentrations and hence emissions contribute to outdoor concentrations due to higher indoor than outdoor concentrations along with estimates of losses via ventilation.

    In the context of building applications, phase change materials (PCM), can be defined as any heat storage material that can absorb a large amount of thermal energy while undergoing a change in phase, such as from a solid to a liquid phase. The incorporation of PCM into the building envelope can enhance occupant comfort through the reduction of indoor temperature fluctuations. It has also been shown to cause a decrease in the overall energy consumption associated with the heating and cooling of buildings. This paper extended the analysis of the impact of using PCM, which has traditionally focused on homes of ordinary construction, to incorporate low to zero energy homes using a model of the Toronto net zero energy house developed in TRNSYS. The paper provided a description of the TRNSYS model/methodology, with reference to the wall layer used in the net zero energy house, and model of the layout of the net zero energy house in TRYNSYS. The TRYNSYS/type 204 PCM component was also presented along with the simulation results in terms of the temperature profile of the third floor of the net zero energy house on a typical winter day with varying PCM concentrations; the temperature profile of the third floor of the net zero energy house on a typical summer day with varying PCM concentrations; yearly heating/cooling load requirements of the net zero energy house for a variety of thermal mass used; temperature profile of the third floor of the net zero energy house on a typical summer day when PCM and concrete slab was used; yearly temperature profile of the third floor of the net zero energy house, illustrating the impact of using PCM; and the yearly heating/cooling load of the net zero energy house as the concentration of PCM was varied. It was concluded that the use of building integrated PCM can reduce temperature fluctuations considerably in the summer but only slightly in the winter. 16 refs., 1 tab., 8 figs.

    The reproductive safety of selective reuptake inhibitor (SRI) antidepressants needs to be established to provide optimal control of maternal depression while protecting the fetus. To define a child's neurodevelopment following prenatal exposure to SRIs and to account for genetic and environmental confounders in a sibling design using the Toronto Motherisk prospective database. Intelligence and behavior of siblings prenatally exposed and unexposed to SRIs were assessed by using the Wechsler Preschool and Primary Scale of Intelligence-Third Edition, Child Behavior Checklist, and Conners Parent Rating Scale-Revised and subsequently compared. Mothers, diagnosed with depression using DSM-IV, were assessed for intelligence quotient (IQ) and for severity of depressive symptoms with the Center for Epidemiologic Studies Depression scale. Prenatal drug doses and durations of exposure, child's age, child's sex, birth order, severity of maternal depression symptoms, and Full Scale IQ, the primary outcome measure, of both the mother and the child were considered in the analyses. Forty-five sibling pairs (ages 3 years to 6 years 11 months, prenatally exposed and unexposed to SRIs) did not differ in their mean ± SD Full Scale IQs (103 ± 13 vs 106 ± 12; P = .30; 95% CI, -7.06 to 2.21) or rates of problematic behaviors. Significant predictor of children's intelligence was maternal IQ (P = .043, β = 0.306). Severity of maternal depression was a significant predictor of Child Behavior Checklist Internalizing (P = .019, β = 0.366), Externalizing (P = .003, β = 0.457), and Total scores (P = .001, β = 0.494). Drug doses and durations of exposure during pregnancy did not predict any outcomes of interest in the exposed siblings. SRI antidepressants were not found to be neurotoxic. Maternal depression may risk the child's future psychopathology. The sibling design in behavioral teratology aids in separating the effects of maternal depression from those of SRIs, providing stronger

    Enhanced meteorological observations were made during the 2015 Pan and Parapan American Games in Toronto in order to measure the vertical and horizontal structure of lake-breeze events. Two scanning Doppler lidars (one fixed and one mobile), a C-band radar, and a network including 53 surface meteorological stations (mesonet) provided pressure, temperature, humidity, and wind speed and direction measurements over Lake Ontario and urban areas. These observations captured the full evolution (prior, during, and after) of 27 lake-breeze events (73% of observation days) in order to characterize the convective and dynamic processes driving lake breezes at the local scale and mesoscale. The dominant signal of a passing lake-breeze front (LBF) was an increase in dew-point temperature of 2.3 ± 0.3°C, coinciding with a 180° shift in wind direction and a decrease in air temperature of 2.1 ± 0.2°C. Doppler lidar observations over the lake detected lake breezes 1 hour (on average) before detection by radar and mesonet. On days with the synoptic flow in the offshore direction, the lidars observed wedge-shaped LBFs with shallow depths, which inhibited the radar's ability to detect the lake breeze. The LBF's ground speed and inland penetration distance were found to be well-correlated (r = 0.78), with larger inland penetration distances occurring on days with non-opposing (non-offshore) synoptic flow. The observed enhanced vertical motion ({>} 1 m s^{-1}) at the LBF, observed by the lidar on 54% of lake-breeze days, was greater (at times {>} 2.5 m s^{-1}) than that observed in previous studies and longer-lasting over the lake than over land. The weaker and less pronounced lake-breeze structure over land is illustrated in two case studies highlighting the lifetime of the lake-breeze circulation and the impact of propagation distance on lake-breeze intensity.

    Medical congresses often held in highlands. We reviewed several medical issues associated with altitude stress especially while physicians have participated medical congress held in high altitude. Altitude stress, also known as an acute mountain sickness (AMS), is caused by acute exposure to low oxygen level at high altitude which is defined as elevations at or above 1,200 m and AMS commonly occurs above 2,500 m. Altitude stress with various symptoms including insomnia can also be experienced in airplane. AMS and drunken state share many common features in symptoms, neurologic manifestations and even show multiple microbleeds in corpus callosum and white matter on MRI. Children are more susceptible to altitude stress than adults. Gradual ascent is the best method for the prevention of altitude stress. Adequate nutrition (mainly carbohydrates) and hydration are recommended. Consumption of alcohol can exacerbate the altitude-induced impairments in judgment and the visual senses and promote psychomotor dysfunction. For prevention or treatment of altitude stress, acetazolamide, phosphodiesterase inhibitors, dexamethasone and erythropoietin are helpful. Altitude stress can be experienced relatively often during participation of medical congress. It is necessary to remind the harmful effect of AMS because it can cause serious permanent organ damage even though the symptoms are negligible in most cases. PMID:27621942

    Full Text Available As the use of fossil fuel has increased, not only in construction, but also in agriculture due to the drastic industrial development in recent times, the problems of heating costs and global warming are getting worse. Therefore, introduction of more reliable and environmentally-friendly alternative energy sources has become urgent and the same trend is found in large-scale horticulture facilities. In this study, among many alternative energy sources, we investigated the reserves and the potential of various different unused energy sources which have infinite potential, but are nowadays wasted due to limitations in their utilization. In addition, we utilized available unused energy as a heat source for a heat pump in a large-scale horticulture facility and analyzed its feasibility through EnergyPlus simulation modeling. Accordingly, the discharge flow rate from the Fan Coil Unit (FCU in the horticulture facility, the discharge air temperature, and the return temperature were analyzed. The performance and heat consumption of each heat source were compared with those of conventional boilers. The result showed that the power load of the heat pump was decreased and thus the heat efficiency was increased as the temperature of the heat source was increased. Among the analyzed heat sources, power plant waste heat which had the highest heat source temperature consumed the least electric energy and showed the highest efficiency.

  20. Understanding the Impact of Intensive Horticulture Land-Use Practices on Surface Water Quality in Central Kenya

    Full Text Available Rapid expansion of commercial horticulture production and related activities contribute to declining surface water quality. The study sought to understand the impacts on select rivers in Laikipia and Meru, production hotspots. The specific aims were (1 to identify prevailing surface water quality by examining variations of 14 physico-chemical parameters, and (2 to categorize measured surface water quality parameters into land use types highlighting potential pollutant source processes. Water samples were collected in July and August 2013 along 14 rivers in the study area. The data were analyzed using principal component analysis (PCA and discriminant analysis (DA. Principal components (PCs explained 70% of the observed total variability of water quality, indicating a prevalence of heavy metal traces (cadmium, phosphate, and zinc. These were linked to the rigorous use of phosphate fertilizers and copper-based agrochemicals in intensive farming. DA provided four significant (p < 0.05 discriminant functions, with 89.5% correct assignment enabling the association of land use with observed water quality. Concentrations of dissolved solids, electro-conductivity, and salinity spiked at locations with intensive small-scale and large-scale horticulture. Understanding the impacts of intensive commercial horticulture and land use practices on water quality is critical to formulating ecologically sound watershed management and pollution abatement plans.
