The California’s cap-and-trade program (California’s carbon market hereafter) allows forestland owners from any part of the contiguous United States to supply carbon credits to compliance entities. In this study, we estimate South Carolina (SC) private forestland owners’willingness to accept compensations to participate in the California’s carbon market using a contingent valuation method. Results: We estimate forestland owners’mean willingness to accept as$67 per acre per year. Our results reveal higher probability of participation of forestland owners with interests in preserving forest ecosystems than those who do not. Additionally, forestland owners who trust in information about climate change from scientists or government are willing to participate more than those who do not. Conclusions: Various factors hinder landowners’ability to participate in carbon markets. Forestland owners in SC consider legislative uncertainty and long-time commitment as the main barriers to participation in California’s carbon market. From this research, average forestland tenure in SC is 27 years, which is far less than the 100-year time commitment of the California’s carbon market. Of those who agreed to participate, choosing between adopting and not adopting any of the three main forest management practices in the California’s carbon market:28% are likely to adopt improved forest management (IFM) practices, 24% are likely to adopt reforestation due to understocked forestlands, and 14% are likely to adopt avoided conversion. In another development, the concept of aggregation has dominated discussions in the California’s carbon market of late. It is an advocacy to include small-scale forestlands in the California’s carbon market. To aggregate, different forestland owners will combine their forestlands to participate. We find that 79% of SC forestland owners are willing to aggregate to participate. However, this research is unable to determine how much total forestland is available in SC for carbon market. We recommend future research in the State on forestland owners’participation in carbon market should consider evaluating forestland availability.展开更多

It involves the management of competing vegetation necessary to obtain the high yields expected in modern forest plantations via control of interfering plants that influence regeneration outcome, impact timber stand development, and limit native plant and wildlife diversity. It includes cultural control, fire control, mechanical control, biological control, and chemical control. The public perception of forest vegetation management, especially chemical control, is sometimes negative due to health and environmental concerns. It is an important tool in the forest management alternatives available to consulting foresters managing family forest lands (the vast majority of private forest land in the United States). We report on a study that addresses the motivations of family forest owners that implement forest vegetation management practices and the motivation of those who chose not to implement after forester recommendations to do so. For those who do implement forest vegetation management, improvement of wildlife habitat and increased timber growth was the main motivation. For those who did not, cost was the main concern. Size of forest holding plays a major role in determining who will practice intensive forestry.展开更多

Infection with the parasite in human causes toxoplasmosis that may pose a high risk in immunocompromised individuals under certain clinical conditions. Cats are the ultimate hosts of <i>T. gondii</i> where oocysts are formed through mating of male and female gametes. Infected cats can expel <i>T. gondii</i> oocysts in their feces, and thereby capable of pass on a disease to humans and other animals through consumption of foods, vegetables and water that are polluted with cat feces. The study was conducted to detect the presence of anti-<i>T. gondii</i> IgM and IgG antibodies in the blood of individuals with or without cat contact to determine if there is any relationship between cat contacts and <i>T. gondii</i> infection in humans. To address this, we enrolled subjects who contacted with the cat as target group and individuals with no cat contact as control group. Following register of different demographic data (including age, sex, education, foods habit, income status, etc.), whole blood from each enrolled subject of both the target group and control group was collected for serum preparation. <i>T. gondii</i> infected subjects were detected by Toxo Rapid test kit through identifying anti-<i>T. gondii</i> IgM and IgG antibodies in their serum. We found that only three out of twenty subjects who were in contact with cat showed positive IgG response while IgM antibody response was absent for all subjects. When compared with the data from control group, we did not find any significant association (p = 0.33) of cat contact with the transmission <i>of T. gondii</i> into human. However, with this small number of study subjects, we cannot conclusively say that there is no impact of cat contact on the transmission of <i>T. gondii</i> into human. Whether any association exists or not can be ascertained with a large number of subjects from different areas of Bangladesh in a future study in the population.展开更多

Mature seeds ofA. procera were collected from healthy trees in home garden plan- tations from five different districts in Bangladesh and treated with four pre-sowing treatments, i.e., control, immersion in cold water (4~C for 24 h) and immersion in hot water (80~C for 10 min and 100~C for 1 min). The average length, width and thickness of seeds were calculated as 0.502 + 0.485, 0.420 ~ 0.060 and 0.191 ~ 0.118 cm, respectively. Germination was conducted in poly-bags with a mixture of topsoil and cow dung in a ratio of 3:1. The results revealed that pre-sowing treatments affected the rate of germination of seeds, which significantly increased the germination percentages of seeds in hot water treatments compared with those in control (60.60%) and the cold water treatment (4℃ for 24 h, 63.53%). The highest germination success was 82.07% in the treatment of im- mersion in hot water (80℃) for 10 min, followed by 79.00% in immersion in hot water (100℃) for l rain. Germination started 4 to 6 days after seed sowing and completed in a period of 22 to 25 days in all treatments. ANOVAs showed statistically significant dif- ferences (p 〈 0.05) in seed germination starting dates, closing dates, germination percentages and rates of germination among treat- ments, but no significant differences in seed germination starting dates, closing dates, germination period, germination percentages and rates of germination among the seed sources. The study also revealed that the interaction between seed source variation and treat- ment effect significantly differed in seed germination starting dates, closing dates, germination percentages and rates of germination. The hot water (100℃ for 1min) treatment is recommended for seed germination ofA. procera in rural Bangladesh.展开更多

A cross sectional random digit dial survey was conducted with an aim to learn more about who is re-homing, where they are re-homing and why they are re-homing owned dogs and cats in the US. We found the prevalence of re-homing in five years at 6% making for an estimated 6.12 million household re-homing pets every five years. Pets were most likely to be re-homed by being given to a friend or family member (37%) closely followed by being taken to a shelter. Those who re-homed due to a reason related to the pet as opposed to reasons such as family issues were more likely to re-home to a shelter. For respondents who rented, housing reasons were the number one reason for re-homing, and for respondents of lower income, they were significantly more likely to re-home due to cost and housing issues as opposed to pet related issues. We conclude that some reasons for re-homing are not easily modified and humane re-homing is the best option, but that there are many areas in which intervention and prevention programs may increase retention.展开更多

All over the world, especially in developed countries. They handicap the professional activities of the workers. Purpose: To determine the epidemiological profile of dermatosis among automobile repair and maintenance garages in Parakou. Methods: It was a cross-sectional and descriptive study carried out from 20 April to 17 May 2020. The sampling method was non-probabilistic. Data collected from a questionnaire, clinical examination and worksite observation were analyzed with Epi Info 7.2.2.1 software. Results: The participation rate was 98.08%. The sex ratio (male/female) was 178. The mean age of the respondents was 25.80 ± 10.22 years. Respondents with less than 5 years of experience in the field were 61.22%. Mechanics were the most numerous. In the sample, 95.81% had frequent skin contact with fuels, 84.08% had contact with motor oils and 15.92% had contact with dilute battery electrolyte solutions. The frequency of dermatosis was 73.46%. Hands and wrists were the most affected seats (47.35%). Some (33.84%) wore them before the start of the activity in the garage but in 66.22% of them, the dermatosis had occurred because of their arrival in the garage. Among these skin diseases, keratoderma predominated at 80.01%. Conclusion: Dermatosis is very common among garage owners in Parakou.展开更多

Purpose: ...Background: Cimicoxib is a coxib recently licensed in Europe for pain and inflammation associated with osteoarthritis (OA), and the management of perioperative pain due to orthopaedic or soft tissue surgery. Purpose: This prospective study was to complete the product information for the end users by providing additional scientific data obtained after a thirty-day treatment course of cimicoxib in dogs with OA, and to collect owners’ feedback. Data were collected from nine European countries with 492 client owned dogs recruited to the trial. Dogs were treated once daily with 2 mg/kg cimicoxib orally. Immediately before, at Day (D) 15 and D30 after the start of treatment veterinarians and owners scored body condition, appetite, locomotion, lameness, pain on palpation and manipulation of the joint and joint effusion (veterinarians) and dog demeanor and well being (owners). In a subset of dogs, serum urea (n = 191), creatinine (n = 184), AST (n = 141) and ALT (n = 174) were measured at day (D) 0 and D30. Statistical tests were carried out to detect significant changes in the clinical parameters with time. Results and Discussion: Veterinary and owner assessments were analysed from 236 and 215 dogs respectively. Improvements in locomotion, mobility, pain scores and dog demeanor and body condition were identified;outcome measures assessed by veterinarians continued to improve after 15 days of treatment up to the 30-day time point. At D30 a significantly higher number of dogs had an urea concentration superior to the upper limit of the reference range. However, there was no significant difference for creatinine, ALT and AST. Conclusions: A 30-day treatment course with cimicoxib improved locomotion and decreased pain scores in dogs with OA, with minimal adverse effects. These data, support pre-clinical data in dogs receiving cimicoxib and are useful for veterinarians making decisions about which NSAID to administer to dogs that require pain management for OA.展开更多

文摘Background: Carbon sequestration through recommended forest management practices is an ecosystem service that helps mitigate climate change and its impacts while generating carbon credits for forestland owners to sell in cap-and-trade programs. The California’s cap-and-trade program (California’s carbon market hereafter) allows forestland owners from any part of the contiguous United States to supply carbon credits to compliance entities. In this study, we estimate South Carolina (SC) private forestland owners’willingness to accept compensations to participate in the California’s carbon market using a contingent valuation method.

Our results reveal higher probability of participation of forestland owners with interests in preserving forest ecosystems than those who do not. Additionally, forestland owners who trust in information about climate change from scientists or government are willing to participate more than those who do not.

文摘Forest vegetation management has evolved as a recognized component of intensive forest management practice. It involves the management of competing vegetation necessary to obtain the high yields expected in modern forest plantations via control of interfering plants that influence regeneration outcome, impact timber stand development, and limit native plant and wildlife diversity. It includes cultural control, fire control, mechanical control, biological control, and chemical control. The public perception of forest vegetation management, especially chemical control, is sometimes negative due to health and environmental concerns. It is an important tool in the forest management alternatives available to consulting foresters managing family forest lands (the vast majority of private forest land in the United States). We report on a study that addresses the motivations of family forest owners that implement forest vegetation management practices and the motivation of those who chose not to implement after forester recommendations to do so. For those who do implement forest vegetation management, improvement of wildlife habitat and increased timber growth was the main motivation. For those who did not, cost was the main concern. Size of forest holding plays a major role in determining who will practice intensive forestry.
文摘<i>Toxoplasma gondii</i> is a zoonotic protozoan that can infect any warm-blooded mammal. <i>T. gondii</i> infects about one-third of the human population on the planet. Infection with the parasite in human causes toxoplasmosis that may pose a high risk in immunocompromised individuals under certain clinical conditions. Cats are the ultimate hosts of <i>T. gondii</i> where oocysts are formed through mating of male and female gametes. Infected cats can expel <i>T. gondii</i> oocysts in their feces, and thereby capable of pass on a disease to humans and other animals through consumption of foods, vegetables and water that are polluted with cat feces.

文摘Searchable Encryption(SE)enables data owners to search remotely stored ciphertexts selectively.A practical model that is closest to real life should be able to handle search queries with multiple keywords and multiple data owners/users,and even return the top-k most relevant search results when requested.We refer to a model that satisfies all of the conditions a 3-multi ranked search model.However,SE schemes that have been proposed to date use fully trusted trapdoor generation centers,and several methods assume a secure connection between the data users and a trapdoor generation center.That is,they assume the trapdoor generation center is the only entity that can learn the information regarding queried keywords,but it will never attempt to use it in any other manner than that requested,which is impractical in real life.In this study,to enhance the security,we propose a new 3-multi ranked SE scheme that satisfies all conditions without these security assumptions.The proposed scheme uses randomized keywords to protect the interested keywords of users from both outside adversaries and the honest-but-curious trapdoor generation center,thereby preventing attackers from determining whether two different queries include the same keyword.Moreover,we develop a method for managing multiple encrypted keywords from every data owner,each encrypted with a different key.Our evaluation demonstrates that,despite the trade-off overhead that results from the weaker security assumption,the proposed scheme achieves reasonable performance compared to extant schemes,which implies that our scheme is practical and closest to real life.

文摘An experiment in seed morphology and seed germination techniques of Albizia procera was carried out in the nursery of the Forestry and Wood Technology Discipline, Khulna University, Bangladesh in order to discover the source variation in seeds and pre-sowing treatment effects on seed germination. Mature seeds ofA. procera were collected from healthy trees in home garden plan- tations from five different districts in Bangladesh and treated with four pre-sowing treatments, i.e., control, immersion in cold water (4~C for 24 h) and immersion in hot water (80~C for 10 min and 100~C for 1 min). The average length, width and thickness of seeds were calculated as 0.502 + 0.485, 0.420 ~ 0.060 and 0.191 ~ 0.118 cm, respectively. Germination was conducted in poly-bags with a mixture of topsoil and cow dung in a ratio of 3:1. The results revealed that pre-sowing treatments affected the rate of germination of seeds, which significantly increased the germination percentages of seeds in hot water treatments compared with those in control (60.60%) and the cold water treatment (4℃ for 24 h, 63.53%). The highest germination success was 82.07% in the treatment of im- mersion in hot water (80℃) for 10 min, followed by 79.00% in immersion in hot water (100℃) for l rain. Germination started 4 to 6 days after seed sowing and completed in a period of 22 to 25 days in all treatments. ANOVAs showed statistically significant dif- ferences (p 〈 0.05) in seed germination starting dates, closing dates, germination percentages and rates of germination among treat- ments, but no significant differences in seed germination starting dates, closing dates, germination period, germination percentages and rates of germination among the seed sources. The study also revealed that the interaction between seed source variation and treat- ment effect significantly differed in seed germination starting dates, closing dates, germination percentages and rates of germination. The hot water (100℃ for 1min) treatment is recommended for seed germination ofA. procera in rural Bangladesh.

文摘Background: Occupational dermatoses, also called occupational dermatitis or occupational dermatitis, are very common in the workplace and are still a topical subject. All over the world, especially in developed countries. They handicap the professional activities of the workers. Purpose: To determine the epidemiological profile of dermatosis among automobile repair and maintenance garages in Parakou. Methods: It was a cross-sectional and descriptive study carried out from 20 April to 17 May 2020. The sampling method was non-probabilistic. Data collected from a questionnaire, clinical examination and worksite observation were analyzed with Epi Info 7.2.2.1 software. Results: The participation rate was 98.08%. The sex ratio (male/female) was 178. The mean age of the respondents was 25.80 ± 10.22 years. Respondents with less than 5 years of experience in the field were 61.22%. Mechanics were the most numerous. In the sample, 95.81% had frequent skin contact with fuels, 84.08% had contact with motor oils and 15.92% had contact with dilute battery electrolyte solutions.

文摘The realty(real estate)management of ownership of buildings includes the owner(homeowner)entrust-management and the owner self-management,the former through the way of realty service contracts,the latter through the resolution of the owners’assembly and the owners’committee.The legal disputes of realty service contracts involve balancing interests among the realty service enterprise,individual owner,and all the owners.We should use dynamic balancing of the interests of the three parties to implement the interests of the win-win cooperation rather than the interests of the trade-off of“all or nothing.”The realty service contract is similar to the entrustment contract,both of which are based on the owners’entrustment.The duty to provide realty service is not simply equivalent to fiduciary duty.The realty service contract has the essence of both behavior debt and result debt.For the former,the general provisions of the entrustment contract can be referred to,and for the latter,the general provisions of the contract for work can be referred to.In view of the group characteristics of the realty service contract,owners have no right to terminate the realty service contract at any time but should obey the principle of due process and take the majority mechanism to make a dismissal resolution resolution.The resolutions and management stipulations worked out by the owners’assembly in a majority mechanism,both of which belong to resolution behavior and are legal tools of the owners’autonomy,shall be binding on all the owners.The relationship between the owner,the owner’s assembly,and the owner’s committee is similar to the fiduciary relationship.If the decision made by the owners’assembly or the owners’committee and the management stipulation infringes upon the legal rights and interests of the owners,the injured owner has the right to revocation litigation.At present,residential commodity owners have a relatively low degree of autonomy in China,and legal disputes over realty services are frequent.In the future,we need to perfect the legal incentive and constraint measures,and stimulate the vitality of owner autonomy to promote better implementation of the owner self-management and owner entrust-management.

文摘Background: Cimicoxib is a coxib recently licensed in Europe for pain and inflammation associated with osteoarthritis (OA), and the management of perioperative pain due to orthopaedic or soft tissue surgery. Purpose: This prospective study was to complete the product information for the end users by providing additional scientific data obtained after a thirty-day treatment course of cimicoxib in dogs with OA, and to collect owners’ feedback. Data were collected from nine European countries with 492 client owned dogs recruited to the trial. Dogs were treated once daily with 2 mg/kg cimicoxib orally. Immediately before, at Day (D) 15 and D30 after the start of treatment veterinarians and owners scored body condition, appetite, locomotion, lameness, pain on palpation and manipulation of the joint and joint effusion (veterinarians) and dog demeanor and well being (owners). In a subset of dogs, serum urea (n = 191), creatinine (n = 184), AST (n = 141) and ALT (n = 174) were measured at day (D) 0 and D30. Statistical tests were carried out to detect significant changes in the clinical parameters with time. Results and Discussion: Veterinary and owner assessments were analysed from 236 and 215 dogs respectively. Improvements in locomotion, mobility, pain scores and dog demeanor and body condition were identified;outcome measures assessed by veterinarians continued to improve after 15 days of treatment up to the 30-day time point. At D30 a significantly higher number of dogs had an urea concentration superior to the upper limit of the reference range. However, there was no significant difference for creatinine, ALT and AST. Conclusions: A 30-day treatment course with cimicoxib improved locomotion and decreased pain scores in dogs with OA, with minimal adverse effects. These data, support pre-clinical data in dogs receiving cimicoxib and are useful for veterinarians making decisions about which NSAID to administer to dogs that require pain management for OA.
