Objectives Food puzzles may provide enrichment to domestic cats. The purpose of our survey was to determine: (1) how respondents fed their cat (type[s] of food, amount and mode of delivery); (2) how many people used food puzzles to provide food for their cats; and (3) owner attitudes about food puzzles. Methods We conducted an online survey from January to April of 2018 to ask cat owners (n = 3192) questions related to their cat feeding practices and use of food puzzles. Results Most cat owners fed their cats dry food, with half of those owners offering it ad libitum. Thirty percent of participants offered food puzzles to their cats; another 18% had tried food puzzles but were no longer using them. The remaining participants had never used a food puzzle with their cat. Reasons for not using food puzzles included perceptions about the cat (eg, being too lazy), multiple pets in the home, pets fed different diets, health issues and feeding an exclusively wet food diet. Many participants did not know how to choose or introduce a food puzzle to their cat, and many non-users saw no need or benefit to their cat. Conclusions and relevance This survey provided information about the feeding habits of cat owners and why they do and do not use food puzzles with their cats. Because of the scarcity of empirical evidence about the effects of food puzzles on pet cat welfare, more research is needed to determine the role of food puzzles as part of an overall enrichment plan.

Full textAbstract:
Carvacrol is an active ingredient of essential oils from different plants, mainly from oregano and thyme species. It poseses biocidal activity agains many artropodes of the importance for veterinary and human medicine. Carvacrol acts as repelent, larvicide, insecticide and acaricide. It acts against pest artropodes such as those that serve as mechanical or biological vectors for many causal agents of viral, bacterial and parasitic diseases for animals and humans. Therefore, it may be used not only in pest arthropodes control but in vector borne diseases control, too. In the paper carvacrol bioactivity against mosquitoes, house flies, cockroaches, ticks and mites are described. Potencial modes of carvacrol action on artropodes are given, too. Carvacrol reachs its biotoxicity against arthropodes alone or in combination with other active ingredients from the same plant of its origin, such as tymol, cymen or others. The paper explains reasons for frequently investigations on essential oils and other natural products of plant origin to their biotoxicity against food stored pest or pest of medicinal importance, as well as, needs for their use in agriculture, veterinary and human medicine.

Full textAbstract:
Non-chemical methods for weed management are becoming important as fewer herbicides are labelled for use and as the market demands pesticide-free produce. We have studied the use of interplanted cover crops in strawberry plantings as an alternative/supplement to chemical weed management. Several different cover crops (tall fescue, marigold and sudangrass) were seeded between rows of newly planted strawberries in late June as runnering was commencing. An additional seeding of sudangrass was made in late July. For comparison, untreated plots and diphenamid treated plots were included in the experimental design. Measurements were taken throughout the season of soil moisture, light levels, crop nutrient concentrations, nematode numbers in soil and crop roots, runner biomass, and weed composition and biomass. Cover crops were incorporated in late fall and the planting was mulched. The following spring, crop nutrient concentrations, nematode numbers in soil and crop roots, weed composition and biomass, yield, individual fruit size, and aboveground strawberry biomass was assessed. The marigolds were too competitive for moisture to be an effective companion cover crop. The early planting of sudangrass was too tall, and fescue was too competitive for nutrients. The untreated plots contained many more weeds than other treatments, nematode levels were higher in the strawberry roots in these plots, and harvesting fruit was very difficult. The late seeding of sudangrass, however, provided significant weed control while not reducing yield relative to herbicide-treated plots.

As an entry point, this paper uses the media coverage of Dana Keistimewaan in TribunJogja daily newspaper, a non-partisan press institution that established at post New Order era. UsingRobert Entman’s framing analysis, this research argues that consolidation of democracy has not yet fullyembedded at regional level. Local presspays too many att ention on technocratic administrative aspects, rather than democratic ones that may involve contribution of the people.

Abstract This book is extensively illustrated, and addresses both fundamental traditional techniques and new methodologies. The chapters aim to provide an introduction to basic techniques for laboratory and field work with plant-parasitic and free-living soil-dwelling nematodes. The coverage highlights areas that have expanded and/or become more widespread over recent years, such as techniques used in diagnostic laboratories, including computerized methods to count and identify nematodes, and the use of entomopathogenic nematodes as environmentally acceptable control systems for some insect pests. The use of molecular techniques is relevant to many areas of work on nematodes and basic information on current molecular methodologies and their various applications is included.

Full textAbstract:
Pests, parasites and pathogenic agents have exerted a notable influence on the process of economic development of pre-industrial Europe, in view of their influence on the health, longevity and reproduction of human beings, plants and animals. On each occasion man has reacted to biological uncertainty with responses that were public or private, formal or informal and differed in both efficacy and cost. Success has always been partial, and dependent on experience, knowledge and the investment of economic resources. These reciprocal influences have never been allocated an appropriate or convincing place in the institutional model or those of Smith, Malthus, Ricardo or Marx, typically exploited to describe and explain the flux and reflux of the economic development of pre-industrial Europe. In these proceedings of Study Week promoted by the Fondazione Datini, the leading experts in the sector have undertaken to analyse, exemplify and discuss the precise nature of the complex interactions between economic and biological processes and agents. Adopying a stimulating, innovative and interdisciplinary approach, they appraise the degree to which such processes acted in reciprocal independence, whether there was a significant co-evolution and what prospects there are for developing explanatory models that better grasp the essentially bilateral nature of such interactions.

Full textAbstract:
Abstract Since the discovery of RNA interference in 1998 as a potent molecular tool for the selective downregulation of gene expression in almost all eukaryotes, increasing research is being performed in order to discover applications that are useful for the pharmaceutical and chemical industry. The ease of use of double-stranded RNA for targeted in vivo gene silencing in animal cells and tissues gave birth to a massive interest from industry in order to discover biotechnological applications for human health and plant protection. For insects, RNAi became the 'Holy Grail' of pesticide manufacturing, because this technology is a promising species-specific environmentally friendly approach to killing natural enemies of cultured plants and farmed animals. The general idea to use RNAi as a pest-control agent originated with the realization that dsRNAs that target developmentally or physiologically important insect genes can cause lethal phenotypes as a result of the specific gene downregulation. Most importantly to achieve this, dsRNA is not required to be constitutively expressed via a transgene in the targeted insect but it can be administrated orally after direct spraying on the infested plants. Similarly, dsRNAs can be administered to pests after constitutive expression as a hairpin in plants or bacteria via stable transgenesis. Ideally, this technology could have already been applied in integrated pest management (IPM) if improvements were not essential in order to achieve higher insecticidal effects. There are many limitations that decrease RNAi efficiency in insects, which arise from the biochemical nature of the insect gut as well as from deficiencies in the RNAi core machinery, a common phenomenon mostly observed in lepidopteran species. To overcome these obstacles, new technologies should be assessed to ascertain that the dsRNA will be transferred intact, stable and in high amounts to the targeted insect cells. In this chapter we will review a wide range of recent discoveries that address the delivery issues of dsRNAs in insect cells, with a focus on the most prominent and efficient technologies. We will also review the upcoming and novel use of viral molecular components for the successful and efficient delivery of dsRNA to the insect cell.

Full textAbstract:
AbstractClimate change is a global issue threatening food security, environmental safety, and human health in tropical and developing countries where people depend mainly on agriculture for their livelihood. Nigeria ranks among the top in the global yam production. It has the largest population in Africa and has been able to secure food for its growing population through food crops especially yam. Unfortunately, the recent increase in termites’ colonies due to climate change threatens yam yield. Besides harming man and environment, pesticides are expensive and not easily accessible to control the pests. This prompted a study which aimed at applying a biotrado-cultural approach in controlling the termites, as well as improving soil chemical properties and yam production. The study hypothesized that Chromolaena odorata and Elaeis guineensis sludge improved soil nutrient and yam yield and consequently decreased termites’ outbreak. In a randomized design experiment of five blocks and five replicates, five different treatments including unmanaged (UM), Vernonia amygdalina (VA), Chromolaena odorata (CO), Elaeis guineensis (EG) liquid sludge, and fipronil (FP) were applied in termites-infested agricultural soil. Data were collected and measured on the responses of soil chemical properties, termites, and yam yield to treatments using one-way ANOVA, regression, and multivariate analyses. The result showed that Chromolaena odorata (CO) and EG treatments were the best treatments for controlling termites and increase yam production. Termites were successfully controlled in VA and FP treatments, but the control was not commensurate with yam production. The experiment needs to be extended to other locations in the study region. It also requires an intensive and long-term investigation in order to thoroughly understand (i) the influence of climate change on the termites’ outbreak, (ii) the extent of termite damage to the crops, (iii) the impacts of climate change and variability on yam yields, (iii) the agricultural and economic benefits of the applied treatments, and (iv) the ecological and human health safety of the treatments.

Full textAbstract:
In crops management, it is important to estimate the damage effected by pests since the degree of damage will determine the level of pest activity. Pest activity usually involves their life stage and its presence in the field. In addition, pest management in crops is a crucial problem and may yield losses if it is not handled properly. Consequently a forecasting tool is needed to predict the level of pest activity. This is important so that an early treatment or action can be applied before more damage to the plant occurs. Accordingly, the fuzzy expert system may facilitate the user through a consultation session in order to forecast the pest activity in the rice field. A set of questions will be asked to help users diagnose their given symptom in order to infer such a conclusion. Figure 1 shows the main components of an expert system including inference engine, expert, knowledge base, working memory, and user interface. The consultation performed by the expert system also involves fuzzy logic to deal with the natural and uncertainty data. Besides, all the information and knowledge about the pests, treatment control measures and prevention steps are managed in the specific knowledge base created in the system. This system is able to educate and inform the farmers and smallholders about pests and their activities in the rice field.

Full textAbstract:
‘Applied ecology’ looks at the application of ecological theories in modelling renewable resources and population dynamics, particularly in relation to species we wish to control or preserve. The collapse of cod fisheries shows the consequences when the bottom of the food chain (changes in phytoplankton) impacts the top. Changes in climate and fire regimes in America’s forests suggests current models may no longer be sustainable in future. How do species mixes help alleviate pressure from pests or pathogens? Successes in the lab have failed in the field, or not taken into account alternative problems that arise from manipulating the ecosystem. Biological and pest control strategies require a holistic approach.

Full textAbstract:
Abstract Delamination of mold compound from top-of-die surfaces in plastic encapsulated microcircuits (PEMs) can alter overall package stresses and cause wire bond or other types of mechanical failure. Liquid water may collect in these delaminated regions and cause metal corrosion. Exceedingly small quantities, even fractions of a monolayer, of adsorbed contamination on die may hinder intimate adhesion of the mold compound to the die surface and cause plastic to delaminate. This paper discusses the consequences of top-of-die delamination (TODD), surface contamination derived from wafer tape mounting that can cause it, and cleaning chemistry to remove surface contaminants in order to minimize it.

Today’s customers see the product not only based on its functionality and its value, but also based on its aesthetic view. And from day to day, the level of consumers’ aesthetic satisfaction is advanced. Companies have to struggle in recognizing and feeding the customers with higher and higher level of aesthetics design, in order to win the competition. Kansei Engineering is a powerful tool during product designs that analyze the design in relation with consumers’ feeling toward the product. In this saturated market, moreover, the application of Kansei Engineering might be a way out to provide a product emotionally attached to the customers’ feeling. PET bottles, particularly bottles distributed in Japan, is an example of “everyday-beverage-container” which has many variations in the shape. Among the many product attributes, product form/shape is one of the product attribute that can attract emotional attachment to the customer. In this paper, physical attributes of PET bottle which evoke consumers to have certain emotional attachment were evaluated using Kansei Engineering. In order to do this, 18 models of PET bottle generated using Taguchi Methods, and 9 emotional evaluation words were applied in a questionnaire. By using Taguchi Methods, important shape parameters that evoke customer to certain emotional feeling were identified. Validation to the Taguchi Methods’ finding was validated using Artificial Neural Network (ANN). The validation was performed by mapping the Kansei/emotional space to shape parameter space. Evaluation towards the result from Taguchi Methods and ANN was performed. Comparison between Taguchi Methods’ and ANN’s result showed that both result were correlated.

It has been shown in thermodynamic simulations of gasification that recycling up to 25% of carbon dioxide (CO2) into a reformer allows for a highly hydrogen (H2) concentrated syngas. While understanding thermodynamic limits is imperative, a kinetic analysis is desired to confirm applicability. Studies on thermal decomposition kinetics of polyethylene terephthalate (PET) in CO2 gasification atmosphere have been assessed. Using thermal gravimetric analysis, we can show that gasification may be modeled as a series of single step reactions and determine the activation energies, pre-exponential factors and reaction models of those reactions. The use of CO2/air atmosphere instead of air atmosphere results in better char conversion.

Full textAbstract:
It is difficult to separate technology from education because technology is embedded in teaching. The best technology for teaching is the one that does not interfere with the communication between the teacher and the students. In other words, it should be barely “noticeable” in how it is used, and easy enough to use that it does not require special training, such as window in a room to see the flowers outside, without interfering in any way. The technology used during an in-person classes is so basic, transparent, and simple, since it consists of a classroom, chairs, blackboard and pieces of chalk. However, a piece of chalk could break. In this case, the flow of information is interrupted; which is why the plastic whiteboards and markers are preferable and cleaner. An electronic board may seem to be better with its many improvements with computers; however, its higher technology could get in the way if it is not used properly. During the pandemic, different technologies, like computers and cell phones, connected to internet were massively used. Yet, computers and cell phones with the appropriate software and apps had an additional cost; with no guarantee of antivirus applications against viruses or worms, leaving aside protection for documents, software and hardware. On top of that, a Zoom, Google or any similar online platform was necessary. Using these platforms, other technologies had to be relied on, including Ethernet or a USB adapter. On the other hand, in developing countries before the pandemic, low-tech was used by most students to store and pass information to their peers and teachers. They would use mainly pens and notebooks to write notes, or CD-Rs or USB to pass information. However, during the pandemic, with the advances in internet speed, many students have now moved on to using e-mail and cloud drives where they can transport their files. All the electronics listed to make online education or tech-based education needed electricity to work. In other words: no electricity, no class; no electric supply or stored electricity in batteries, no class. In this paper we analyze the role of technology in education, and how this technology could enhance or obstruct the communication between the teacher and the students.

In ASME 2015 International Design Engineering Technical Conferences and Computers and Information in Engineering Conference. American Society of Mechanical Engineers, 2015. http://dx.doi.org/10.1115/detc2015-46686.
Full textAbstract:
The origami-based folded core has a broad prospect in applications. However, the fabrication difficulties limit its developments due to the complicate structures with multiple zigzags and fluctuations. In this study, several feasible methods to fabricate polymer origami-based folded core were proposed. Based on the analysis of folded structural features, the vacuum forming process of polymer V-type folded core was deeply investigated. Wall thickness distributions of the folded structure on polyvinyl chloride (PVC) and polyethylene terephthalate (PET) sheets were measured. The results showed that the wall thickness along the straight crease line presents a single peak distribution, while that along the zigzag one shows a dual peak distribution, and the wall thickness of the top zigzag crease line is more uniform and large than that of the bottom one. The mold temperature, polymer sheet temperature and material properties of polymer have great influence on product thickness. Vacuum forming is a feasible way to fabricate polymer origami-based folded core, and the high-quality fabrication of folded structure may be accomplished by designing more reasonable forming mold and selecting optical process parameters.

Full textAbstract:
Co-combustion of coal with biomass or firing biomass alone is used more and more in a first step in meeting the Finnish commitments under the Kyoto protocol. A frequently used technique for firing mixtures of fuels is fluidized bed combustion (FBC). Firing coal, co-combustion with biomass or firing biomass alone may, however, lead to unwanted ash-related problems. Prediction of ash formation behavior can help to avoid these problems before taking new fuels into use. Standard fuel analyses have shown to provide insufficient information for proper prediction especially when considering fuel mixtures. In an attempt to minimize the number of lab scale and pilot scale combustion experiments an extensive database is under development. This database contains data used as input for prediction models such as standard fuel analyses, results from stepwise leaching experiments, SEM/EDS analyses of original and partly burned-out fuels and thermodynamic estimations of the melting behavior of the fuels. Today the database contains 51 fuels, i.e. 8 bark fuels, 10 wood fuels, 3 annual biomasses, 8 peats, 6 coals and 16 miscellaneous fuels, such as RDF, sludge, hulls and husks, bagasse and other residues. Standardized fuel analysis is available for all fuels; melting calculations have been carried out for some 33 fuels. SEM/EDS analysis has been carried out for 20 fuels. The extended utilization of these data with computational fluid dynamic modeling (CFD) has proven to be a useful tool in prediction of deposits in FBC boilers. An example of the prediction tool shows the ability of deposit formation prediction.

The alternative energy facilities, to be built on St. Croix and St. Thomas, have a projected cost of $440 million and will convert an estimated 146,000 tons per year of municipal solid waste into refuse-derived fuel (RDF) using WastAway Services® technology, which will be combined with petroleum coke as fuel in fluidized bed combustion facilities to generate steam and electric power. These sustainable projects will provide 33 MW of electric power to St. Thomas and St. John and 16 MW of electric power to St. Croix, and will help to provide long-term cost stability for electric power and solid waste management in the Territory. Construction is expected to start in spring 2010 with an anticipated completion date during the fourth quarter of 2012. This procurement is a significant achievement for the U.S. Virgin Islands. When the projects are fully implemented, they will allow the Territory to reduce its dependence on oil, recover the energy value and certain recyclable materials from its municipal solid waste, and divert this waste from landfill. Since VIWMA has the responsibility to collect and/or dispose of solid waste year-round, having a system incorporating multiple solid waste processing lines and an adequate supply of spare parts on hand at all times is crucial to meeting the daily demands of waste receiving and processing, and RDF production. Also, with the location of the US Virgin Islands in a hurricane zone, and with only one or two combustion units available in each Project, the ability to both stockpile waste pre-RDF processing and store the produced RDF is very important. Gershman, Brickner & Bratton, Inc. (GBB)’s work has included a due diligence review of the Projects and providing professional support in VIWMA’s negotiations with AEG. GBB’s initial primary assignment centered on reviewing the design and operations of the RDF processing systems that will be built and operated under the respective Service Contracts. VIWMA needed to undertake a detailed technical review of the proposed RDF processing system, since this was the integration point of the waste collection system and waste processing/disposal services. GBB, in association with Maguire, was requested to provide this review and present the findings and opinions to VIWMA. In the completion of this effort, which included both a technical review and participation in negotiations to advance the Service Contracts for the Projects, GBB made direct contact with the key equipment suppliers for the Projects proposed by AEG. This included Bouldin Corporation, the primary RDF processing system supplier, with its patented WastAway technology, and Energy Products of Idaho, the main thermal processing equipment supplier, with its fluidized bed combustion technology and air pollution control equipment. Additionally, since the combustion systems for both Projects will generate an ash product that will require marketing for use and/or disposal over the term of the Service Contracts, GBB made contact with LA Ash, one of the potential subcontractors identified by AEG for these ash management services. Due to the nature of the contract guarantees of VIWMA to provide 73,000 tons per year of Acceptable Waste to each Project for processing, VIWMA authorized GBB to perform a current waste stream characterization study. Part of this effort included waste sorts for one week each in February 2009 on St. Croix and March 2009 on St. Thomas, with the results shared with VIWMA and AEG, as compiled. The 2009 GBB waste stream characterization study incorporated historical monthly waste weigh data from both the Bovoni and Anguilla Landfills that were received from VIWMA staff. The study has formed a basis for continuing to augment the waste quantity information from the two landfills with the additional current monthly results compiled by VIWMA staff going forward following the waste sorts. The final GBB report was published in December 2009 and includes actual USVI landfill receipt data through August 31, 2009. The information contained in this document provides the underpinnings to allow for better tracking and analysis of daily, weekly and monthly waste quantities received for recycling, processing and disposal, which are important to the overall waste processing system operations, guarantees and cost projections. GBB’s annual projections are that the total waste on St. Croix is currently over 104,000 tons per year and over 76,000 tons per year on St. Thomas. The thermal processing technology selected for both Projects is a fluidized bed process, employing a heated bed of sand material “fluidized” in a column of air to burn the fuel — RDF and/or Pet Coke. As such, the solid waste to be used in these combustion units must be size-reduced from the myriad of sizes of waste set out at the curb or discharged into the large roll-off boxes or bins at the many drop-off sites in the US Virgin Islands. While traditional RDF would typically have several days of storage life, the characteristics of the pelletized RDF should allow several weeks of storage. This will be important to having a sound and realistic operating plan, given the unique circumstances associated with the climate, waste moisture content, island location, lack of back-up disposal options and downtime associated with the Power Generation Facility. During the negotiations between AEG and VIWMA, in which GBB staff participated, in addition to RDF and pelletized RDF as the waste fuel sources, other potential fuels have been discussed for use in the Projects and are included as “Opportunity Fuels” in the Service Contracts. These Opportunity Fuels include ground woody waste, dried sludges, and shredded tires, for example. Therefore, the flexibility of the EPI fluidized bed combustion boilers to handle multi-fuels is viewed as an asset over the long term, especially for an island location where disposal options are limited and shipping materials onto and off of each island is expensive. This presentation will provide a unique behind-the-scenes review of the process that led to this historic agreement, from the due diligence of the proposed technologies, to implementation planning, to the negotiations with the contractor. Also discussed will be the waste characterization and quantity analysis performed in 2009 and the fast-track procurement planning and procurement of construction and operating services for a new transfer station to be sited on St. Croix.

Full textAbstract:
Black and turkey vultures cause problems in several ways. The most common problems associated with vultures are structural damage, loss of aesthetic value and property use related to offensive odors and appearance, depredation to livestock and pets, and air traffic safety. Management of these diverse problems often can be addressed by targeting the source of the birds causing the problem, namely the roost where the birds spend the night. Often the roost itself is the problem, such as when birds roost on a communication tower and foul the equipment with their feces or when they roost in a residential area. Several methods are available for roost dispersal. Vultures are protected by the Migratory Bird Treaty Act, and are managed by the federal government. Vultures may be harassed without federal permits, but can be killed only after obtaining a Migratory Bird Depredation Permit from the U.S. Fish and Wildlife Service. State wildlife agencies may require state permits prior to killing migratory birds.

Managers are challenged with the impact of problematic plants, including exotic, invasive, and pest plant species. Information on the cover, distribution, and location of these plants is essential for developing risk-based approaches to managing these species. Based on surveys conducted in 2006, 2011, 2015, and 2019, Heartland Network staff and contractors identified a cumulative total of 28 potentially problematic plant taxa in Arkansas Post National Memorial. Of the 23 species found in 2019, we characterized 9 as very low frequency, 7 as low frequency, 5 as medium frequency, and 2 as high frequency. Cover of all species was low with a single species slightly exceeding a 1-acre threshold based on a midpoint estimate. Efforts to control the woody invasive black locust, Chinese privet, and hardy orange appear to have successfully reduced the cover of these plants across the Memorial Unit. Japanese stiltgrass may have been increasing as recently as 2015, but a combination of recent flooding and control efforts may have stemmed the spread of this invasive grass. Efforts to control localized patches of Chinaberry tree also appear to have reduced the cover of this species. Outside of the problematic species currently subject

Based on surveys conducted in 2008, 2011, 2015, and 2019, Heartland Network staff and contractors identified a cumulative total of 51 potentially problematic plant species in Hopewell Culture National Historical Park. Of the 37 species found in 2019, we characterized 7 as very low frequency, 9 as low frequency, 17 as medium frequency, and 4 as high frequency. Of these, midpoint cover estimates of 2 medium frequency and 2 high frequency species exceeded the 10-acre threshold. Because of the number, extent, and cover of problematic plants in the park and the small park size, control efforts should focus on treating high priority species across the entire park. High priority species may include plant species capable of rapid spread, species at low population levels, and species which can effectively be controlled.

Full textAbstract:
This study was conducted in selected provinces of Bicol Region from April 2015 to May 2015 to describe the knowledge, attitudes and practices (KAP) of dog owners regarding rabies and dog bites. A purposive sampling was used in selecting the respondents of the study. Frequencies were tabulated for all variables. Of the 1,200 respondents, 2,193 dogs were recorded making a 2:1 ratio of dogs to householders in this particular study. Among these dogs 58% were vaccinated against rabies. The majority of the ones taking care of the dogs were female (57.3%) but the primary owner (62.9%) was the head of the family. Only 34.7% of the respondents knew that it is their duty to get their pets vaccinated against rabies. Around one-fourth (20.7%) admitted that someone in their household had been bitten by a dog but most respondents (62.5%) did nothing to the dog. The majority (57.7%) of the bite victims were youths (1-14 years old) and almost all (82.7%) of the wound bites were washed with soap and water. Television (44.9%) was the primary source of knowledge about rabies. The majority of participants (67.3%) said that humans are the main end-hosts that can be infected with rabies. Salivation or drooling (42.7%) and craziness (34.2%) were the main signs cited as behaviour of rabid dogs while craziness (40.2%) and hydrophobia or fear of water (25.4%) were cited for rabid humans. Most (33.9%) do not know the source of rabies but the majority (61.8%) believe that vaccination is the main preventive measure against rabies. The majority of participants (63%) reported that the local ordinances regarding rabies in their locality is about the Local Anti-Rabies Act and almost all (93.2%) admitted that vaccination is the most common anti-rabies program of the government.

Full textAbstract:
A great deal of energy can be sourced both directly and indirectly from waste. For example, municipal waste with an energy content of around 60 petajoules is incinerated in Switzerland every year. The energy recovered directly from this waste covers around 4 % of the Swiss energy demand. However, the greatest potential offered by waste management lies in the recovery of secondary raw materials during the recycling process, thus indirectly avoiding the energy-intensive production of primary raw materials. In order to optimise the contribution to the energy turnaround made by waste management, as a first step, improvements need to be made with respect to the transparent documentation of material and cash flows, in particular. On the basis of this, prioritisation according to the energy efficiency of various recycling and disposal channels is required. Paper and cardboard as well as plastic have been identified as the waste fractions with the greatest potential for improvement. In the case of paper and cardboard, the large quantities involved result in considerable impact. With the exception of PET drinks bottles, plastic waste is often not separately collected and therefore offers substantial improvement potential. Significant optimisation potential has also been identified with regard to the energy efficiency of incineration plants. To allow municipal solid waste incineration (MSWI) plants to use the heat they generate more effectively, however, consumers of the recovered steam and heat need to be located close by. A decisive success factor when transitioning towards an energy-efficient waste management system will be the cooperation between the many stakeholders of the federally organised sector. On the one hand, the sector needs to be increasingly organised along the value chains. On the other hand, however, there is also a need to utilise the freedom that comes with federal diversity in order to test different solutions.

Brandt, Leslie A., Cait Rottler, Wendy S. Gordon, et al. Vulnerability of Austin’s urban forest and natural areas: A report from the Urban Forestry Climate Change Response Framework. U.S. Department of Agriculture, Northern Forests Climate Hub, 2020. http://dx.doi.org/10.32747/2020.7204069.ch.
Full textAbstract:
The trees, developed green spaces, and natural areas within the City of Austin’s 400,882 acres will face direct and indirect impacts from a changing climate over the 21st century. This assessment evaluates the vulnerability of urban trees and natural and developed landscapes within the City Austin to a range of future climates. We synthesized and summarized information on the contemporary landscape, provided information on past climate trends, and illustrated a range of projected future climates. We used this information to inform models of habitat suitability for trees native to the area. Projected shifts in plant hardiness and heat zones were used to understand how less common native species, nonnative species, and cultivars may tolerate future conditions. We also assessed the adaptability of planted and naturally occurring trees to stressors that may not be accounted for in habitat suitability models such as drought, flooding, wind damage, and air pollution. The summary of the contemporary landscape identifies major stressors currently threatening trees and forests in Austin. Major current threats to the region’s urban forest include invasive species, pests and disease, and development. Austin has been warming at a rate of about 0.4°F per decade since measurements began in 1938 and temperature is expected to increase by 5 to 10°F by the end of this century compared to the most recent 30-year average. Both increases in heavy rain events and severe droughts are projected for the future, and the overall balance of precipitation and temperature may shift Austin’s climate to be more similar to the arid Southwest. Species distribution modeling of native trees suggests that suitable habitat may decrease for 14 primarily northern species, and increase for four more southern species. An analysis of tree species vulnerability that combines model projections, shifts in hardiness and heat zones, and adaptive capacity showed that only 3% of the trees estimated to be present in Austin based on the most recent Urban FIA estimate were considered to have low vulnerability in developed areas. Using a panel of local experts, we also assessed the vulnerability of developed and natural areas. All areas were rated as having moderate to moderate-high vulnerability, but the underlying factors driving that vulnerability differed by natural community and between East and West Austin. These projected changes in climate and their associated impacts and vulnerabilities will have important implications for urban forest management, including the planting and maintenance of street and park trees, management of natural areas, and long-term planning.
