    Programs designed to address domestic violence often name empowerment of women as a major program goal. However, programs do not necessarily define what empowerment for survivors of domestic violence entails. This review examines the literature on empowerment, including characteristics of an empowerment process and critiques of empowerment. Diversity of goals for empowerment and differences in access to resources for women experiencing domestic violence are explored as two major factors that should inform program development. Recommendations are offered for developing programs to address domestic violence that support women engaged in an empowerment process.

    The implementation of an Integrity Management Program (IMP) in a crude oil pipeline system is focused on the accomplishment of two primary corporative objectives: to increase safety operation margins and to optimize available resources. A proactive work philosophy ensures the safe and reliable operation of the pipeline in accordance with current legislation. The Integrity Management Program is accomplished by means of an interdisciplinary team that defines the strategic objectives that complement and are compatible with the corporative strategic business plan. The implementation of the program is based on the analysis of the risks due to external corrosion, third party damage, design and operations, and the definition of appropriate mitigation, inspection and monitoring actions, which will ensure long-term integrity of the assets. By means of a statistical propagation model of the external defects, reported by high-resolution magnetic inspection tool (MFL), together with the information provided by corrosion sensors, field repair interventions, close internal surveys and operation data, projected defect depth; remaining strength and failure probability distributions were obtained. From the analysis, feasible courses of action were established, including the inspection and repair plan, the internal inspection program and both corrosion monitoring and mitigation programs.

    Martin, Sandra L; Moracco, Kathryn E; Chang, Judy C; Council, Carol L; Dulli, Lisa S

    2008-09-01

    This article discusses the results of a survey of North Carolina domestic violence programs that found that substance abuse problems are common among program clients, yet only half of the programs had policies concerning substance-abusing clients, and one fourth had memoranda of agreement with substance abuse treatment providers. Most programs with shelters asked clients about substance use; however, one third of the shelters would not admit women if they were noticeably under the influence of substances while seeking shelter residence, instead referring them to substance abuse programs. Approximately one tenth of the domestic violence programs did not have any staff or volunteers with training in substance abuse issues. Implications are discussed.

    Routine enquiry about domestic violence during pregnancy is accepted best practice. Training is essential to improve knowledge and practice. Few studies have undertaken a comprehensive evaluation of training impact over time. To evaluate the longitudinal impact of a domestic violence training and support program to promote midwives' routine antenatal enquiry for domestic violence using a mixed methods design. Data sources included (1) surveys of midwives at 6 months post-training, (2) interviews with key stakeholders at 12 months, (3) chart audit data of screening, risk, and disclosure rates (for 16 months). Measures included midwives' knowledge, preparation for routine enquiry, knowledge of domestic violence and perceptions of impact of the training and support for practice change. Forty (out of 83) participant surveys could be matched and responses compared to baseline and post-training scores. Wilcoxon signed-rank test identified that all 6-month follow-up scores were significantly higher than those at baseline. Level of preparedness increased from 42.3 to 51.05 (Z=4.88, p90%) reported improved confidence to undertake routine inquiry. A chart audit of screening rates revealed that of the 6671 women presenting for antenatal care, nearly 90% were screened. Disclosure of domestic violence was low (violence declining referral. Training, support processes, and referral pathways, contributed to midwives' sustained preparedness and knowledge to conduct routine enquiry and support women disclosing domestic violence.

    2014-01-01

    This paper is devoted to develop an approximation method for scheduling refinery crude oil operations by taking into consideration the demand uncertainty. In the stochastic model the demand uncertainty is modeled as random variables which follow a joint multivariate distribution with a specific correlation structure. Compared to deterministic models in existing works, the stochastic model can be more practical for optimizing crude oil operations. Using joint chance constraints, the demand uncertainty is treated by specifying proximity level on the satisfaction of product demands. However, the joint chance constraints usually hold strong nonlinearity and consequently, it is still hard to handle it directly. In this paper, an approximation method combines a relax-and-tight technique to approximately transform the joint chance constraints to a serial of parameterized linear constraints so that the complicated problem can be attacked iteratively. The basic idea behind this approach is to approximate, as much as possible, nonlinear constraints by a lot of easily handled linear constraints which will lead to a well balance between the problem complexity and tractability. Case studies are conducted to demonstrate the proposed methods. Results show that the operation cost can be reduced effectively compared with the case without considering the demand correlation.

    Full Text Available Background and Purpose: The World Health Organization declared violence against women a top priority for health and emphasized the importance of the world's attention to the prevention and control programs. This study was conducted aimed to identify the training needs of married women referring to health centers in Ahvaz with the objective of enabling the design of a program to prevent violence. Methodology: This sectional study consisted of two qualitative and quantitative studies. In qualitative study, the opinions of 30 married women residing in Ahvaz were collected and analyzed in four focus group discussions. using a validated and reliable questionnaire, the knowledge, attitude, self-efficacy and performance of 320 married women in area of domestic violence were identified Findings: 79% of the women surveyed had adequate awareness about violence against women. 34% of the target group in the field of domestic violence against women has had the right attitude and more than 80% of them stated that violence by men is considered inevitable and natural. 89% of the target group expressed lack of efficacy for the prevention of domestic violence against women. The findings also suggest that there is significant relationship between education and early marriage with violent behavior. Conclusion: providing proper education and awareness to women and group discussion and clarification in order to change attitudes and increase efficacy in abused women against domestic violence are the necessary strategies which result in changing attitudes of women and increasing empowerment of women against domestic violence.

    Adolescents exposed to domestic violence are at high risk for dating abuse. This randomized controlled trial evaluated a dating abuse prevention program designed specifically for this risk group. Moms and Teens for Safe Dates consisted of six mailed booklets of dating abuse prevention information and interactive activities. Mothers who had been victims of domestic violence but no longer lived with the abuser delivered the program to their adolescents who had been exposed to the abuse. Mother and adolescent pairs (N = 409) were recruited through community advertising; the adolescents ranged from 12 to 16 years old and 64 % were female. Mothers and adolescents completed baseline and 6-month follow-up telephone interviews. Booklet completion in the treatment group ranged from 80 % for the first to 62 % for the last booklet. The analyses first tested whether program effects on dating abuse varied by four a priori identified moderators (mother's psychological health, the amount of adolescent exposure to domestic violence, and adolescent sex and race/ethnicity). Main effects of the program were examined when there were no differential program effects. Program effects on psychological and physical victimization and psychological and cyber perpetration were moderated by the amount of adolescent exposure to domestic violence; there were significant favorable program effects for adolescents with higher, but not lower levels of exposure to domestic violence. There were no moderated or main effects on sexual violence victimization and perpetration or cyber victimization. The findings suggest that a dating abuse prevention program designed for adolescents exposed to domestic violence can have important positive effects.

    It is unclear whether racial differences in treatment effect exist for individuals in substance abuse and domestic violence programs. This study examined racial differences in treatment effect among substance dependent Caucasian and African-American male intimate partner violence (IPV) offenders court mandated to an integrated substance abuse and domestic violence treatment. From baseline to completion of treatment (week 12), 75 participants (39 Caucasian; 36 African-American) were assessed on demographics, substance use, legal characteristics, and use of violence (physical, verbal, and psychological). African-American men served more months incarcerated in their life than Caucasian men. Both groups showed decreases in their use of physical violence and alcohol abuse over treatment. Caucasian men also showed a decrease in their use of verbal abuse. At treatment completion, both groups showed a reduction in physical abuse and alcohol abuse. Caucasian men showed a reduction in their use of verbal abuse, but African-American men did not. Substance dependent African-American male IPV offenders may benefit from interventions that thoroughly target communication skills in addition to issues of substance abuse and IPV to reduce use of verbal abuse and improve treatment outcomes among African American men.

    School officials across the country have recognized that many of their students live in homes where domestic violence occurs. As a result, several elementary schools have implemented education-based programs focused on this issue. The current study evaluates the efficacy of the "I Wish the Hitting Would Stop . . . " program that was presented to elementary school children in two school districts in the Midwest. This study examines the level of knowledge retention by students who participated in the "I Wish the Hitting Would Stop . . . " program during the 2010-2011 and 2011-2012 academic years. Fourth- and fifth-grade students responded to open-ended questions regarding their understanding of domestic violence and their retention of the concepts presented in the "I Wish the Hitting Would Stop . . . " curriculum. While the results suggest that students retain the information presented in the program, there also appears to be a gender difference in knowledge retention. © The Author(s) 2014.

  19. Bringing trauma-informed practice to domestic violence programs: A qualitative analysis of current approaches.

    Wilson, Joshua M; Fauci, Jenny E; Goodman, Lisa A

    2015-11-01

    Three out of 10 women and 1 out of 10 men in the United States experience violence at the hands of an intimate partner-often with devastating costs. In response, hundreds of residential and community-based organizations have sprung up to support survivors. Over the last decade, many of these organizations have joined other human service systems in adopting trauma-informed care (TIC), an approach to working with survivors that responds directly to the effects of trauma. Although there have been various efforts to describe TIC in domestic violence (DV) programs, there is a need to further synthesize this discourse on trauma-informed approaches to better understand specific applications and practices for DV programs. This study aimed to address this gap. The authors of this study systematically identified key documents that describe trauma-informed approaches in DV services and then conducted a qualitative content analysis to identify core themes. Results yielded 6 principles (Establishing emotional safety, Restoring choice and control, Facilitating connection, Supporting coping, Responding to identity and context, and Building strengths), each of which comprised a set of concrete practices. Despite the common themes articulated across descriptions of DV-specific trauma-informed practices (TIP), we also found critical differences, with some publications focusing narrowly on individual healing and others emphasizing the broader community and social contexts of violence and oppression. Implications for future research and evaluation are discussed. (PsycINFO Database Record (c) 2015 APA, all rights reserved).

    This qualitative study is part of a mixed methods research project that examined the effectiveness of the primary rehabilitation program for domestic violence offenders in the Israeli Prison Services-the "House of Hope." The quantitative part of the study showed that the "House of Hope" program was effective in reducing recidivism among participating inmates. The purpose of this qualitative study was to describe the rehabilitation program according to the perspectives of the program staff. For this purpose, semistructured interviews were conducted with the department staff during the study as well as with past directors. The qualitative findings suggested that the success of the program probably stemmed from a synergistic combination of several components, for example, identifying the characteristics of domestic violence offenders and adjusting treatment programs to their needs, along with exposure to psychological treatment in varied therapies (cognitive behavioral therapy, psychoeducational, and psychodynamic) and formats (group therapy and individual therapy) during a 1-year stay in a hierarchical therapeutic community. Other components mentioned are staff professionalism, stability, and the program's location in a therapeutic-oriented prison that is architecturally designed and built to create a less stressful environment for the inmates and the staff.

    Significant off-campus domestic study away experiences have been shown to be a transformative active learning environment for students and achieve similar learning outcomes as study abroad programs. This manuscript describes the conception, development, and pedagogical approach of a faculty-led domestic study away experience in New York City for pre-licensure and post-licensure nursing students as an active learning strategy for developing cultural competence. Students participated in service-learning activities that illuminated the realities and challenges persons from other cultures face as they interact with health care in a culture that is not their own. In partnership with New York Cares©, students were immersed in well-established ongoing sustainable community-based projects. These experiences fostered reflective conversations between community members, student participants, and faculty regarding social factors, cultural issues and needs, and global issues and trends. Through the New York study away program, students were able to broaden their perspectives about social factors and culture beyond geographic or ethnic boundaries and apply these service experiences to their nursing practice. Study away programs are an excellent strategy for nursing educators to prepare students for care of multicultural populations and for proficiency in cultural competency within the globalization of the United States. © 2016 Wiley Periodicals, Inc.

    to determine the effect of birth cohort on dental fluorosis in Mexican schoolchildren during the implementation of the national program to fluoridate domestic salt. in a cross-sectional study we examined 1,644 schoolchildren 6-13 years old born between 1985-1992 in Campeche, México; a community where there is negligible naturally available fluoride in water supplies. Dental fluorosis was assessed with the Dean’s index in the permanent dentition. Questionnaires were used to identify diverse socio-demographic and socio-economic variables. In the statistical analysis logistic regression was used. the prevalence of fluorosis was 15.5%. In the multivariate model,we observed fluorosis was associated with larger family sizes (OR: 0.91; 95% CI: 0.84-0.99) and female sex (OR: 0.74; 95%CI: 0.57-0.98). Furthermore, using the cohort of 1985 as a comparison group, no significant dental fluorosis differences were found with those born between 1986-1987; in contrast, in the cohorts born between 1989-1992 the risk of dental fluorosis increased by almost four times (p fluorosis was low compared to other studies in Mexico. In this community with negligible fluoride in water supplies the likelihood of dental fluorosis increased as the windows of susceptibility in birth cohorts were closer to the chronologic beginning of the national domestic salt fluoridation program in 1991. This trend was more apparent after 1991.

    Research has attempted to elucidate men and women's proximal motivations for perpetrating intimate partner violence (IPV). However, previous research has yet to clarify and resolve contention regarding whether motives for IPV are gender-neutral or gender specific. Thus, the purpose of this present study was to compare motives for physical IPV perpetration among a sample of men (n =90) and women (n =87) arrested for domestic violence and court-referred to batterer intervention programs. Results demonstrated that the most frequently endorsed motives for IPV by both men and women were self-defense, expression of negative emotions, and communication difficulties. With the exception of expression of negative emotions and retaliation, with women endorsing these motives more often than men, there were no significant differences between men and women's self-reported reasons for perpetrating physical aggression. The implications of these findings for future research and intervention programs are discussed.

    Indonesia depends heavily on revenues from the export of LNG and oil, the availability of which appears to be decreasing. It is therefore making a strong effort to accelerate development of a domestic natural gas industry. A high priority has been given to the conversion of power plants and city gas systems, including local industries and commercial facilities, from liquid fuels to natural gas. This will release more oil for export, help to meet the objectives of Repelita V, and provide substantial environmental benefits. The World Bank recently provided loans to the Indonesian Government for two projects that are aimed at substituting natural gas for oil and manufactured gas in domestic markets. One project involves expansion of the gas distribution systems of Indonesia's natural gas utility (PGN) in three cities: Jakarta and Bogor in Java, and Medan in Sumatra. The project also includes training programs for PGN staff and an energy pricing policy study to be carried out by Indonesia's Ministry of Mines and Energy. The second project involves expansion of the supply of natural gas for Surabaya and twelve other towns in its vicinity in East Java, and further expansion of Medan's supply system. Technical assistance will be provided to enhance the skills ofPGN and the Ministry of Mines and Energy, and a Gas Technology Unit similar to the Institute of Gas Technology will be established at Indonesia's Research and Development Center for Oil and Gas (LEMIGAS) in Jakarta. 14 refs., 3 figs., 11 tabs.

    World War II not only brought the United States rapidly into the nuclear age, but it also brought a new term, {open_quotes}safeguards.{close_quotes} By that time, physical security was an already established activity that dealt with the protection of possessions such as property, vehicles, and other valuables. A secret nuclear project under a stadium at the University of Chicago would add a new dimension to physical security. Similarly, a community known only by its post office box at a location 27 miles from Santa Fe, New Mexico (PO Box 1663) would initiate new programs to protect information and technology while their programs changed the science and warfare around the world. The Manhattan Project and what was to become the Los Alamos Scientific Laboratory (now Los Alamos National Laboratory) would extend the applications of physical security and, soon to be implemented, safeguards to produce important technical advances for the protection, accounting, control, and nonproliferation of fissile nuclear materials. Security for nuclear materials and weapons information began as a foremost consideration with the start of the nuclear programs in the early 1940s. In the 1960s, the Atoms for Peace Program promoted the peaceful use of nuclear energy and made the US a supplier of nuclear materials and peaceful-use nuclear technology to other states. This program also changed the focus on nuclear materials from that of worldwide control to inspection by an independent agency, the proposed International Atomic Energy Agency. At this same time the nuclear weapons states increased from three to five. Other nations worked to obtain a nuclear weapons capability, resulting in increasing concerns about nuclear proliferation.

    This study seeks to estimate the prevalence of psychological and physical violence practiced against children in the family environment among clients of the Family Medical Program in Niterói (RJ). It also discloses some potential opportunities for action in the prevention, early detection and monitoring of families experiencing violence. This population-based survey was conducted with face-to-face interviews with parents or legal sponsors of 278 children registered in 27 teams of the Family Health Program. The population studied was randomly selected among children up to ten years of age. The Brazilian version of Parent-Child Conflict Tactics Scales - CTSPC was employed to assess the occurrence of this type of violence. Psychological aggression occurred in 96.7% (CI 95%: 94.7-98.8) of the households, and corporal punishment occurred in 93.8% (CI 95%: 92.0-96.7). Minor physical violence was reported by 51.4% (CI 95%: 45.5-57.3) of the respondents, and severe physical maltreatment by 19.8% (CI 95%: 15.1-24.5) of them. Although the mother was the foremost perpetrator of all kinds of maltreatment, most of the children were abused by both parents. In view of these results, domestic violence against children should be seen as a main concern for the Family Health Program.

    This study was conducted to assess the effectiveness of empowerment program on increasing self-esteem, learned resourcefulness, and coping ways in women exposed to domestic violence. This experimental study was conducted between October 2012 and June 2014 in the obstetrics and gynaecology departments of the Giresun Maternity Hospital, and at the Family Counseling Center (FCC) in Turkey. Sixty women who agreed to participate in the study were randomly assigned into two groups. Data were collected by the Coopersmith Self-Esteem Inventory (SEI), The Rosenbaum's Learned Resourcefulness Scale (RLRS), and the Ways of Coping Inventory (WCI). The assessment of the women before and after the empowerment program showed that women in the intervention group showed significant improvements in the SEI, RLRS, and WCI scores compared with controls. These results suggest that the empowerment program is an effective practice for increasing the levels of self-esteem, learned resourcefulness, and coping ways of women exposed to domestic violence.

    Despite the extensive use of constructed wetland (CW) as an effective method for domestic wastewater treatment, there is lack of clarity in arriving at well-defined design guidelines. This is particularly due to the fact that the design of CW is dependent on many inter-connected parameters which interact in a complex manner. Consequently, different researchers in the past have tried to address different aspects of this complexity. In this study, an attempt is made to model the influence of relative humidity (RH) in the effectiveness of BOD5 removal. Since it is an accepted fact that plants respond to change in humidity, it is necessary to take this parameter into consideration particularly when the CW is to be designed involving changes in relative humidity over a shorter time horizon (say a couple of months). This study reveals that BOD5out depends on the ratio of BOD5in and relative humidity. An attempt is also made to model the outlet BOD5 using genetic programming with inlet BOD5 and relative humidity as input parameters.

    High sulfur crude oil is desulfurized by a low temperature (25-80 C.) chlorinolysis at ambient pressure in the absence of organic solvent or diluent but in the presence of water (water/oil=0.3) followed by a water and caustic wash to remove sulfur and chlorine containing reaction products. The process described can be practiced at a well site for the recovery of desulfurized oil used to generate steam for injection into the well for enhanced oil recovery.

    Full Text Available Domestic violence is a problem that affects the lives of many women both in urban and rural areas. Depression and post-traumatic stress disorder are the most prevalent mental health problems related with domestic violence. Children of battered women are also affected from the domestic violence. Children who grow up in families with intimate partner violence may suffer from a range of behavioral and emotional disturbances that can be associated with the perpetration or experiencing of violence later in life. The mental health care sector can have a significant impact on publicizing and addressing violence against women and children and on reducing the mental health problems related to abuse. This review focuses on domestic violence victims, most of whom are women and children victimized by their spouses or parents, along with the causes and cycle of domestic violence.

    The external security threat is known as the most important factor of nuclear weapons program, the domestic politics situation can also affect the nuclear proliferation decision of a country. For example, when a leader wants nuclear weapons as an ultimate weapon, the domestic politics situation can determine the effectiveness of the weapons program of a country. This study analyzes the current knowledge of the relationship between domestic politics and nuclear proliferation and suggests the main challenges of the quantitative models trying to calculate nuclear proliferation risk of countries. The domestic politics status is one of the most important indicators of nuclear program. However, some variables have never been used in quantitative analyses; for example, number of veto players and the public opinion on nuclear weapons; despite they are considered to be important in various qualitative studies. Future studies should focus on how should they be coded and how can they be linked with existing domestic politics variables.

    2012-07-01

    Over time, recommended best practices for crude unit materials selection have evolved to accommodate new operating requirements, feed qualities, and product qualities. The shift to heavier oil processing is one of the major changes in crude feed quality occurring over the last 20 years. The three major types of crude unit corrosion include sulfidation attack, naphthenic acid attack, and corrosion resulting from hydrolyzable chlorides. Heavy oils processing makes all three areas worse. Heavy oils have higher sulfur content; higher naphthenic acid content; and are more difficult to desalt, leading to higher chloride corrosion rates. Materials selection involves two major criteria, meeting required safety standards, and optimizing economics of the overall plant. Proper materials selection is only one component of a plant integrity approach. Materials selection cannot eliminate all corrosion. Proper materials selection requires appropriate support from other elements of an integrity protection program. The elements of integrity preservation include: materials selection (type and corrosion allowance); management limits on operating conditions allowed; feed quality control; chemical additives for corrosion reduction; and preventive maintenance and inspection (PMI). The following discussion must be taken in the context of the application of required supporting work in all the other areas. Within that context, specific materials recommendations are made to minimize corrosion due to the most common causes in the crude unit. (author)

    To conduct a benefit-cost analysis of the results of the domestic dog and coyote (DDC) oral rabies vaccine (ORV) program in Texas from 1995 through 2006 by use of fiscal records and relevant public health data. Retrospective benefit-cost analysis. Procedures-Pertinent economic data were collected in 20 counties of south Texas affected by a DDC-variant rabies epizootic. The costs and benefits afforded by a DDC ORV program were then calculated. Costs were the total expenditures of the ORV program. Benefits were the savings associated with the number of potentially prevented human postexposure prophylaxis (PEP) treatments and animal rabies tests for the DDC-variant rabies virus in the epizootic area and an area of potential disease expansion. Total estimated benefits of the program approximately ranged from $89 million to $346 million, with total program costs of $26,358,221 for the study period. The estimated savings (ie, damages avoided) from extrapolated numbers of PEP treatments and animal rabies tests yielded benefit-cost ratios that ranged from 3.38 to 13.12 for various frequen-cies of PEP and animal testing. In Texas, the use of ORV stopped the northward spread and led to the progressive elimination of the DDC variant of rabies in coyotes (Canis latrans). The decision to implement an ORV program was cost-efficient, although many unknowns were involved in the original decision, and key economic variables were identified for consideration in future planning of ORV programs.

    Court-mandated domestic violence (DV) treatment programs across the country have seen a marked increase in female clients. These programs use a variety of measurement tools to assess the needs of their clients. Increased numbers of women in treatment for DV reflect a need to address the measurement of intimate partner violence (IPV) for both males and females. Unfortunately, the reliability and validity of many of measures used to assess IPV and related constructs for women remains unknown. The current study focuses on a particular measure, the Propensity for Abusiveness Scale (PAS). The PAS is not a measure of abusive behavior per se; rather, it assesses risk factors for abuse, including affective lability, anger expression, trauma symptoms, and harsh parenting experienced by the respondent. Specifically, the current study compares the factor structure and the measurement properties of the PAS for males and females in a sample of 885 (647 female, 238 male) participants in a DV treatment program. Findings indicate that the PAS demonstrated configural, metric, and scalar invariance between the female and male samples. These results suggest that it is appropriate for researchers and clinicians to make comparisons between women and men based on PAS factor scores. © The Author(s) 2014.

    Effective prevention of domestic accidents in children includes regimental and/or legislative action, information for parents and education of the children. The latter two strategies have been applied in the deparment of the Doubs in a cooperative health promotion program. Preschool and kindergarten structures were chosen and the pedagogical project involved acquainting the children with the idea of danger by use of a kit prepared by the "Comité Français d'Education pour la Santé" (French Committee for health education). This study was set up in two stages: "experimental" in 2 schools (1983-1984) and "operational" in 40 schools (1984-1985). In order to evaluate it, the population was divided into a control group and an experimental group. A total of 5,720 tests were carried out among 520 children. 494 parents and 82 teachers answered the questionnaires sent to them. The teachers were generally very positive about the effectiveness of education about dangers and the teaching activities which could be employed: discovery of environment, awareness of body, a.s.o. The changes in attitude were real and enduring among children. The parents changed their behavior significantly concerning the storing of poisonous products (medicines and household cleaning products), which allows to feel that this program can be effective in terms of risk reduction.

    More than 600 oil wells were destroyed in Kuwait by Iraqi in 1991. During the war, over 300 oil lakes with depth of up to 2m at more than 500 different locations which has been over 49km2. Therefore, approximately 22 million m3was crude oil contaminated. As exposure of more than 20 years under atmospheric conditions of Kuwait, the crude oil has volatile hydrocarbons and covered heavy oily sludge under the crude oil lake. One of crude oil contaminated soil which located Burgan Oilfield area was collected by Kuwait Oil Company and got by H-plus Company. This contaminated soil has about 42% crude oil and could not biodegraded itself due to the extremely high toxicity. This contaminated soil was separated by 2mm sieve for removal oil sludge ball. Total petroleum hydrocarbons (TPH) was analysis by GC FID and initial TPH concentration was average 48,783 mg/kg. Ten grams of the contaminated soil replaced in two micro reactors with 20mL of bio surfactant produce microorganism. Reactor 1 was added 0.1g powder hemoglobin and other reactor was not added hemoglobin at time 0 day. Those reactors shake 120 rpm on the shaker for 7 days and CO2 produced about 150mg/L per day. After 7 days under the slurry systems, the rest days operated by hemoglobin as primary carbon source for enhanced biodegradation. The crude oil contaminated soil was degraded from 48,783mg/kg to 20,234mg/kg by slurry process and final TPH concentration degraded 11,324mg/kg for 21days. Therefore, highly contaminated soil by crude oil will be combined bio slurry process and biodegradation process with hemoglobin as bio catalytic source.

    This interim report is designed to show the present status of the Geological Survey's information and the parts of a comprehensive program necessary to improve our information about the raw material resources of uranium and thorium. Rarely in geologic work has it been necessary. to determine so completely a nation's resources of useful minerals in so brief a span of time. Ordinarily, information on mineral resources Is accumulated during a long period of years. However, uranium and thorium were suddenly thrust from a position of subsidiary economic interest into one of great strategic importance. Information concerning their occurrence must, therefore, be obtained as rapidly as reliable methods of investigation will permit. Accordingly the program must be at once comprehensive and carried out over an area more extensive than is usual in the search for and appraisal of most other mineral resources.

    This report is one of a series of publications assessing the feasibility of increasing domestic heavy oil (10{degrees} to 20{degrees} API gravity) production. This report provides a compendium of the United States refining industry and analyzes the industry by Petroleum Administration for Defense District (PADD) and by ten smaller refining areas. The refining capacity, oil source and oil quality are analyzed, and projections are made for the U.S. refining industry for the years 1990 to 2010. The study used publicly available data as background. A linear program model of the U.S. refining industry was constructed and validated using 1990 U.S. refinery performance. Projections of domestic oil production (decline) and import of crude oil (increases) were balanced to meet anticipated demand to establish a base case for years 1990 through 2010. The impact of additional domestic heavy oil production, (300 MB/D to 900 MB/D, originating in select areas of the U.S.) on the U.S. refining complex was evaluated. This heavy oil could reduce the import rate and the balance of payments by displacing some imported, principally Mid-east, medium crude. The construction cost for refining units to accommodate this additional domestic heavy oil production in both the low and high volume scenarios is about 7 billion dollars for bottoms conversion capacity (delayed coking) with about 50% of the cost attributed to compliance with the Clean Air Act Amendment of 1990.

    This qualitative case study aimed to analyze the challenges faced by the Family Health Program (FHP) teams in dealing with domestic violence against children and adolescents in Teresópolis, Rio de Janeiro State, Brazil. The sample consisted of 25 professionals from three family health teams. Data were collected through face-to-face semi-structured thematic interviews and submitted to content analysis. Findings included the health professionals' detection of cases of domestic violence among families enrolled in the program, often associated with drug use and drug dealing, alcoholism, family breakdown, and poverty. Collaboration with the community and difficulty in inter-sector actions were identified as challenges for detecting, reporting, and monitoring cases. Most professionals felt insecure in dealing with such cases, due to lack of appropriate knowledge and skills. The study concludes that it is essential to managers, staff and community discuss the problem and means to approach it in the context of the territories.

    Characterization of crude glycerol is very important to its value-added conversion. In this study, the physical and chemical properties of five biodiesel-derived crude glycerol samples were determined. Three methods, including iodometric-periodic acid method, high performance liquid chromatography (HPLC), and gas chromatography (GC), were shown to be suitable for the determination of glycerol content in crude glycerol. The compositional analysis of crude glycerol was successfully achieved by crude glycerol fractionation and characterization of the obtained fractions (aqueous and organic) using titrimetric, HPLC, and GC analyses. The aqueous fraction consisted mainly of glycerol, methanol, and water, while the organic fraction contained fatty acid methyl esters (FAMEs), free fatty acids (FFAs), and glycerides. Despite the wide variations in the proportion of their components, all raw crude glycerol samples were shown to contain glycerol, soap, methanol, FAMEs, water, glycerides, FFAs, and ash.

    To isolate and analyze the chemical composition in different crude extracts of from the leaves of locally grown of Thymus vulgaris L (T. vulgaris) by gas chromatography-mass spectrometry (GC-MS). The shade dried leaves powder was extracted with methanol by using Soxhlet extractor. Methanol crude extracts of T. vulgaris and the derived fractions of hexane, chloroform, ethyl acetate and butanol were obtained. Qualitative analyses of various organic crude extracts of T. vulgaris by using GC-MS showed that there were different types of high and low molecular weight compounds. Most of the isolated and identified compounds by GC-MS in the crude extracts are basically biologically important. Further, the T. vulgaris leaf possessed certain characteristics that can be ascribed to cultivation on a domestic plantation. The crude extracts were prepared from the powder leaves of T. vulgaris for respective compounds can be chosen on the basis of above GC-MS analysis. All the major compounds were identified and characterized by spectroscopic method in different organic crude extracts of T. vulgaris are biologically active molecules. Thus the identification of a good number of compounds in various crude extracts of T. vulgaris might have some ecological role.

    modified their behavior, as have the victims, although for a lesser extent. Perpetrators are increasingly subject to restraining orders, with an obligation to undergo treatment and to attend awareness sessions. Victims are also more likely to go to the police. Social workers, self-help groups and, since 2006, psychologists are now available for victim support in police stations. Management of perpetrators has improved. Finally, despite the continuing reluctance of many physicians, an encouraging trend is emerging among younger members of the profession. A recent survey of 1472 French medical students showed that, while 90 % of them said they had received no training in this area, 93 % considered that doctors should play a role and 95 % said they felt highly concerned. Specific university diplomas have been created and domestic violence is now included in the midwifery curriculum. The delicate question of prevention remains to be resolved; a program is currently being tested.

    Full Text Available This study examines the effects of crude oil price changes on economic activity in an oil dependent economy-Nigeria. A small open economy structural vector autoregressive (SVAR technique is employed to study the macroeconomic dynamics of domestic price level, economic output, money supply and oil price in Nigeria. The sample covers the data from 1985:q1 to 2010:q4. The Impulse Response Functions (IRFs and the Forecast Error Variance Decompositions (FEVDs results suggest that domestic policies, instead of oil-boom should be blamed for inflation. Also, oil price variations are driven mostly by oil shocks, however, domestic shocks are responsible for a reasonable portion of oil price variations.

    Venezuela has reserves of heavy and extra heavy crude oil in the eastern part of the country. There is a need for lower capital cost extraction technologies. At the moment, heavy oil is diluted with light or medium crude oil before it is sold on the market. In order to remove this requirement, PDVSA Research Institute has been working on developing a new technology to convert heavy crude oil into upgraded crude oil. This paper presents the technology, named Aquaconversion, and its applications. The technology consists of a catalytic steam conversion process which converts heavy oil into transportable upgraded crude oil with a higher density and lower viscosity than can be achieved using other technologies. This technology can be used onsite to obtain transportable upgraded crude or to replace visbreaking units in refineries. This paper presents a new technology that makes the extraction of heavy oil in Venezuela economically feasible.

    Coal is the most abundant domestic energy resource in the United States. The Fossil Energy Organization within the US Department of Energy (DOE) has been supporting a coal liquefaction program to develop improved technologies to convert coal to clean and cost-effective liquid fuels to complement the dwindling supply of domestic petroleum crude. The goal of this program is to produce coal liquids that are competitive with crude at $20 to $25 per barrel. Indirect and direct liquefaction routes are the two technologies being pursued under the DOE coal liquefaction program. This paper will give an overview of the DOE indirect liquefaction program. More detailed discussions will be given to the F-T diesel and DME fuels which have shown great promises as clean burning alternative diesel fuels. The authors also will briefly discuss the economics of indirect liquefaction and the hurdles and opportunities for the early commercial deployment of these technologies. Discussions will be preceded by two brief reviews on the liquid versus gas phase reactors and the natural gas versus coal based indirect liquefaction.

    2017-12-01

    In recent decades, significant effort and money have been spent to change social and legal responses to domestic violence and affect public perceptions. A small body of research has examined individuals' opinions about what behaviors are considered domestic violence. Using a sample of college students, the present study examined a modified version of a somewhat popular instrument used to measure beliefs about domestic violence, extending previous work done by Carlson and Worden. Results indicated beliefs about domestic violence are multidimensional, depending on the nature of the behavior and, in part, the gender of the perpetrator. Opinions about the lawfulness of these behaviors fit the same factor structure as beliefs about domestic violence. Demographic characteristics, current relationship status, secondhand experiences with domestic violence, and perceived prevalence of domestic violence in the community are generally not related to beliefs about domestic violence or the lawfulness of these behaviors. However, attributions of blame on the victim are negatively related to domestic violence beliefs and lawfulness. Moreover, lawfulness is a key covariate for domestic violence beliefs. In addition, results also indicate that the gender of the perpetrator is an important variable affecting student's beliefs about sexual assault behaviors. Results from this study support the prevailing ideas behind the Battered Women's Movement that enacting policies and educational programs deeming domestic violence socially, morally, and legally wrong could shift long-standing sociocultural beliefs about men's use of violence against women. Implications of this study for research and policy specific to college students are discussed.

    Full Text Available Kegiatan penambangan minyak bumi tidak hanya dilakukan oleh perusahaan-perusahaan besar, tetapi juga oleh masyarakat secara tradisional. Potensi pencemaran lingkungan yang ditimbulkan oleh kegiatan penambangan rakyat ini menjadi lebih tinggi karena pengelolaannya yang tradisional. Salah satu jenis pencemaran yang ditimbulkannya misalnya adalah tanah atau perairan yang tercemar oleh minyak bumi (crude oil pada saat berlangsungnya kegiatan penambangan. Salah satu upaya untuk dapat mengatasinya adalah dengan bioremediasi. Bioremediasi merupakan teknologi pengolahan pencemar dengan memanfaatkan aktivitas mikroba, terutama dari golongan bakteri. Bioremediasi tersebut harus melibatkan bakteri yang memiliki kapasitas metabolic untuk melakukan biodegradasi terhadap crude oil tersebut. Crude oil sendiri pada dasarnya merupakan senyawa hidrokarbon yang merupakan sumber karbon yang kaya bagi mikroba. Namun demikian, biodegradasi crude oil relative lebih sulit dilakukan karena karakteristiknya yang merupakan senyawa dengan berat molekul dan ukuran yang besar. Oleh karena itu penambahan kosubstrat yang lebih sederhana dapat dilakukan untuk membantu biodegradasi terutama pada tahap awal proses. Penelitian ini dilakukan untuk mengetahui pengaruh penambahan kosubstrat dalam hal ini glukosa terhadap biodegradasi crude oil. Penelitian dilakukan dalam media cair dengan bioaugmentasi melalui penambahan inoculum bakteri yang diisolasi dari tanah yang dikondisikan terhadap crude oil dalam beberapa variasi reactor. Indikasi terjadinya biodegradasi diperiksa melalui pengukuran terhadap parameter Total Petroleum Hydrocarbon (TPH dan Total Plate Count (TPC. Hasil penelitian menunjukkan bahwa penambahan kosubstrat glukosa memberikan pengaruh positif terhadap penurunan TPH. Penurunan TPH tertinggi setelah 28 hari adalah sebesar 25,3 % yang diberikan oleh reactor dengan penambahan kosubstrat serta konsentrasi crude oil awal sebesar 8.1 %. Sementara itu reactor tanpa

Less than 15% of marine sponge crude extracts displayed antibacterial activity, both against susceptible and antibiotic-resistant bacteria. Up to 40% of marine sponge crude extracts displayed antimycobacterial activity against M. tuberculosis H37Rv. Cytotoxicity was observed for 18% of marine sponge crude extracts. Finally, less than 3% of sponge extracts inhibited L-APRT. Less than 10% of ascidian crude extracts displayed antibacterial activity. More than 25% of ascidian crude extracts were active against M. tuberculosis and the three cancer cell lines. Only two crude extracts from the ascidian Polysyncraton sp. collected in different seasons (1995 and 1997 displayed activity against L-APRT. Less than 2% of bryozoan and octocoral crude extracts presented antibacterial activity, but a high percentage of crude extracts from bryozoan and octororal displayed cytotoxic (11% and 30%, respectively and antimycobacterial (60% activities. The extract of only one species of bryozoan, Bugula sp., presented inhibitory activity against L-APRT. Overall, the crude extracts of marine invertebrates herein investigated presented a high level of cytotoxic and antimycobacterial activities, a lower level of antibacterial activity and only a small number of crude extracts inhibited L-APRT. Taxonomic analysis of some of the more potently active crude extracts showed the occurrence of biological activity in taxa that have been previously chemically investigated. These include marine sponges belonging to genera Aaptos, Aplysina, Callyspongia, Haliclona

    Full Text Available This study proposes a multiple kernel learning (MKL-based regression model for crude oil spot price forecasting and trading. We used a well-known trend-following technical analysis indicator, the moving average convergence and divergence (MACD indicator, for extracting features from original spot prices. Additionally, we factored in the possibility that movements of target crude oil prices may be related to other important crude oil markets besides the target market for the prediction time horizon since traders may find price movement information within other relevant crude oil markets useful. We also considered multiple timeframes in this study since trends may differ across different timeframes and, in fact, traders may use their own timeframes. Therefore, for forecasting target crude oil prices, this study emphasizes on features pertaining to other important crude oil markets and different timeframes in addition to features of the target crude oil market and target timeframe. Moreover, the MKL framework has been used to fuse information extracted from different sources and timeframes of the same data source. Experimental results show that out-of-sample forecasting using the MKL method is superior to benchmark methods in terms of root mean square error (RMSE and average percentage profit (APP. They also show that the information from multiple timeframes is useful for prediction, but that from another crude oil market is not.

    The purpose of this work is to present a general summary of the operations which should be performed from the technical point of view, as well as the economic, for arriving at an optimum design for a pipeline and its utilization in the transportation of heavy crude oil. The characteristics are presented of the Boscan field crude which is one of the most difficult in the world to handle. Many of the different insulating coatings are named that have been used for covering piping or equipment which has to operate in a hot environment. Other parts of the study present some of the experiences which have occurred during the transport of heavy crude in cold water. The properties of the crude are listed as well as those of some of the interior coatings including polymers. Equations are given with which to calculate heat loss from heated lines and to determine pressure drop. Various insulation thicknesses are calculated with selection of the most economic value. In some pipelines of considerable length which transport heated heavy crude, it is necessary to provide reheating equipment at one or more locations prior to destination.

    Recently, it became urgent to develop an effective method for repressing the microbials in a crude drug and its preparation. In some countries in Asia and Western countries, radiosterilization for natural drugs has been approved and the dose was within a range. 10-30 kGy. This study aimed to investigate the efficacy and the safety of such radiosterilization for crude drugs. Concerning bacterial contamination in the original materials for crude drugs, the proportion rates of materials containing less than 10{sup 3}, 10{sup 3}-10{sup 4} and more than 10{sup 5} cells were 54, 27 and 19%, respectively. Since the previous study revealed that those microbials were almost diminished by exposure to 10 kGy, various crude drugs were exposed to 5 kGy and the amounts of remaining microbials were determined. The number of microbials remained after radiation at 5 kGy was 1 x 10{sup 3} for plantago seed, rhubarb and cyperus rhizome and less than 10{sup 2} for other samples tested. The effects of radiation on the respective active ingredients of each crude drug underwent using HPLC. (M.N.)

    Energy Technology Data Exchange (ETDEWEB)

    1968-10-01

    Venezuela's Corporacion Venezolana del Petroleo (CVP) is handling heavy crude production at its Boscan Field, using modern facilities. For generating steam, the station has 2 boilers: one is direct fired and the other takes advantage of the waste heat from the turbines. To prevent plugging of the pipeline, when it is necessary to suspend operations, the crude is displaced with water. Delays are not frequent but can occur if problems arise due to difficulties with the boilers. The treating separators, one vertical and the other horizontal, have 2 heaters: one is in the upstream circuit and the other is in the downstream circuit. The crude is separated from naphtha and water in an expansion tower. Three compressors furnish gas to the gas turbines. The suction pressure is 80 psi and the discharge pressure is 150 psi.

    This article investigates the efficacy of a volatility model for three crude oil markets - Brent, Dubai, and West Texas Intermediate (WTI) - with regard to its ability to forecast and identify volatility stylized facts, in particular volatility persistence or long memory. In this context, we assess persistence in the volatility of the three crude oil prices using conditional volatility models. The CGARCH and FIGARCH models are better equipped to capture persistence than are the GARCH and IGARCH models. The CGARCH and FIGARCH models also provide superior performance in out-of-sample volatility forecasts. We conclude that the CGARCH and FIGARCH models are useful for modeling and forecasting persistence in the volatility of crude oil prices. (author)

    Cooking oil in Indonesia is considered to be one of the staple food of Indonesian people. In the beginning of 2008, the price of cooking oil in Indonesia has increased significantly. One of the reasons is the increase of Crude Palm Oil (CPO) price in the international market. The objective of this research is to investigate the impacts of international price of CPO on the domestic price of CPO and cooking oil. Three specific objectives are included (1) To test whether international price of C...

    It has been hypothesized that reproductive isolation should facilitate evolution under domestication. However, a systematic comparison of reproductive barrier strength between crops and their progenitors has not been conducted to test this hypothesis. Here, we present a systematic survey of reproductive barriers between 32 economically important crop species and their progenitors to better understand the role of reproductive isolation during the domestication process. We took a conservative approach, avoiding those types of reproductive isolation that are poorly known for these taxa (e.g., differences in flowering time). We show that the majority of crops surveyed are isolated from their progenitors by one or more reproductive barriers, despite the fact that the most important reproductive barrier in natural systems, geographical isolation, was absent, at least in the initial stages of domestication for most species. Thus, barriers to reproduction between crops and wild relatives are closely associated with domestication and may facilitate it, thereby raising the question whether reproductive isolation could be viewed as a long-overlooked "domestication trait." Some of the reproductive barriers observed (e.g., polyploidy and uniparental reproduction), however, may have been favored for reasons other than, or in addition to, their effects on gene flow.

    We examined rates of animal abuse in pet-owning families experiencing intimate partner violence (IPV). We also examined whether higher levels of IPV (as measured by subscales from the Conflict Tactics Scales) predicted increased risk for partner-perpetrated animal abuse. Our sample included 291 mother-child dyads, where the mothers sought services from domestic violence agencies. Nearly half the sample is comprised of Mexican immigrants. Mothers reported that 11.7% of partners threatened to harm a pet and 26.1% actually harmed a pet, the latter of which represents a lower rate than in similar studies. When examining animal abuse by "Hispanic status," follow-up analyses revealed significant omnibus differences between groups, in that non-Hispanic U.S.-born partners (mostly White) displayed higher rates of harming pets (41%) than either U.S.-born or Mexican-born Hispanic groups (27% and 12.5%, respectively). Differences in rates for only threatening (but not harming) pets were not significant, possibly due to a small number of partners (n = 32) in this group. When examining whether partners' IPV predicted only threatening to harm pets, no IPV subscale variables (Physical Assault, Psychological Aggression, Injury, or Sexual Coercion) were significant after controlling for income, education, and Hispanic status. When examining actual harm to pets, more Psychological Aggression and less Physical Assault significantly predicted slightly higher risk of harm. However, Mexican-born partners had nearly 4 times lower risk of harming a pet. Overall, these results suggest that Hispanic men who are perpetrators of IPV are less likely to harm pets than non-Hispanic perpetrators of IPV, particularly if Mexican-born. Considering that the United States has a significant proportion of Mexican immigrants, it may be worthwhile to explore the topics of IPV and animal abuse within this group. © The Author(s) 2015.

    Under the hot reservoir conditions, waxy crudes behave like Newtonian fluids but once they experience very cold temperatures on the sea floor, the heavy paraffin's begin to precipitate from the solution impacting non- Newtonian flow behavior to the crude (Chang 2000, Lee 2009, Davidson 2004) and begin to deposit on the pipe wall leave blocked of pipeline. This gel cannot be broken with the original steady state flow operating pressure applied before gelation (Chang 1998). Restarting waxy crude oil flows in pipelines is a difficult issue because of the complex rheological behavior of the gelled oil. Indeed, below the WAT, the gelled oil exhibits viscoplastic, thixotropic, temperature-dependent, and compressible properties due to the interlocking gel-like structure formed by the crystallized paraffin compounds and the thermal shrinkage of the oil. The main objective of this work is to determine the minimal pressure to restart the flow, and the relationship between the fluid rheology , pipe geometry and the restart pressure of the flow. Experiments will be performed to investigate the displacement of carbopol aqueous solutions (viscoplastic fluid without thixotropic effects) by Newtonian oil flowing through a strait pipe to validate the experimental apparatus. Therefore, tests will be made with different fluids, like Laponite and waxy crude oils. (author)

  1. Crude oil prices--the direction

    Energy Technology Data Exchange (ETDEWEB)

    Roberts, M.L.

    1983-03-01

    Over the next 12 to 18 months, real crude prices should be flat to down, and thereafter increase at a rate equal to or less than inflation through 1985. This forecast is predicated on the assumption that free-world energy demand will be down by about 4% over the next five years to about 106 million BD crude oil equivalent. Assuming a compound annual growth rate in excess of 4% for non-oil supplies, to about 59 million BD crude oil equivalent, the free world's oil requirements are expected to total about 49 million BD in 1985, up about 7% from 1982's estimated level of about 46 million BD. If these assumptions are correct, they suggest that OPEC supplies will amount to about 76% of their productive capacity, or about 26 million BD, down 16% from 1979's peak level of 31 million BD. Thus, OPEC will have to exercise a self-discipline to prorate itself and thereby be able to maintain price controls over its supplies without seeing the crude price rupture to the mid-$20 per barrel level. During the 1973-1980 period, the demand for energy per $1,000 real GNP declined in excess of 14%, after the real price of energy advanced some 30% in 1973-1974, suggesting a negative price elasticity of 0.48 for the seven OCEP countries which consume about 68% of the world's energy supplies. The current uncertainties associated with conservation, substitution, efficiency and the general economic climate raise serious questions as to what the level of demand for petroleum products will be when the western world regains its economic momentum after the current recession. At that time, we may have a better handle on the price elasticity of energy and the ultimate market clearing price for crude.

    Traditionally, domestic violence in Japan referred to children's physical and emotional violence against their parents. However, in recent years, the general public's awareness of and actions toward other types of domestic violence, especially violence against women and children, has increased. Following a brief description of filial violence and elderly abuse, both spousal abuse and child abuse are discussed in terms of their prevalence and cultural and historical backgrounds. The article concludes with current and future challenges in the intervention of violence, particularly against women and children, in the Japanese family.

    Full Text Available Crude oil is an important energy commodity to mankind. Several causes have made crude oil prices to be volatile. The fluctuation of crude oil prices has affected many related sectors and stock market indices. Hence, forecasting the crude oil prices is essential to avoid the future prices of the non-renewable natural resources to rise. In this study, daily crude oil prices data was obtained from WTI dated 2 January to 29 May 2015. We used Markov Model (MM approach in forecasting the crude oil prices. In this study, the analyses were done using EViews and Maple software where the potential of this software in forecasting daily crude oil prices time series data was explored. Based on the study, we concluded that MM model is able to produce accurate forecast based on a description of history patterns in crude oil prices.

    Crude extract from sweet sorghum supplemented with vetch juice was utilized as the carbohydrate source for fermentative production of lactic acid. Fermentation of media containing 7% (w/v) total sugar was completed in 60-80 hours by Lactobacillus plantarum, product yield averaging 85%. Maximum acid production rates were dependent on pH, initial substrate distribution, and concentration, the rates varying from 2 to 5 g/liter per hour. Under limited medium supplementation the lactic acid yield was lowered to 67%. The fermented ammoniated product contained over eight times as much equivalent crude protein (N x 6.25) as the original medium. Unstructured kinetic models were developed for cell growth, lactic acid formation, and substrate consumption in batch fermentation. With the provision of experimentally determined kinetic parameters, the proposed models accurately described the fermentation process. 15 references.

  11. Volatile hydrocarbons inhibit methanogenic crude oil degradation

    2014-04-01

    Full Text Available Methanogenic degradation of crude oil in subsurface sediments occurs slowly, but without the need for exogenous electron acceptors, is sustained for long periods and has enormous economic and environmental consequences. Here we show that volatile hydrocarbons are inhibitory to methanogenic oil biodegradation by comparing degradation of an artificially weathered crude oil with volatile hydrocarbons removed, with the same oil that was not weathered. Volatile hydrocarbons (nC5-nC10, methylcyclohexane, benzene, toluene and xylenes were quantified in the headspace of microcosms. Aliphatic (n-alkanes nC12-nC34 and aromatic hydrocarbons (4-methylbiphenyl, 3-methylbiphenyl, 2-methylnaphthalene, 1-methylnaphthalene were quantified in the total hydrocarbon fraction extracted from the microcosms. 16S rRNA genes from key microorganisms known to play an important role in methanogenic alkane degradation (Smithella and Methanomicrobiales were quantified by quantitative PCR. Methane production from degradation of weathered oil in microcosms was rapid (1.1 ± 0.1 µmol CH4/g sediment/day with stoichiometric yields consistent with degradation of heavier n-alkanes (nC12-nC34. For non-weathered oil, degradation rates in microcosms were significantly lower (0.4 ± 0.3 µmol CH4/g sediment/day. This indicated that volatile hydrocarbons present in the non-weathered oil inhibit, but do not completely halt, methanogenic alkane biodegradation. These findings are significant with respect to rates of biodegradation of crude oils with abundant volatile hydrocarbons in anoxic, sulphate-depleted subsurface environments, such as contaminated marine sediments which have been entrained below the sulfate-reduction zone, as well as crude oil biodegradation in petroleum reservoirs and contaminated aquifers.

    The crude palm oil industry is an agro-industrial commodity. The global market of this industry has experienced rapid growth in recent years, such that it has a strategic value to be developed for Indonesian economy. Despite these economic benefits there are a number of environmental problems at the factories, such as high water consumption, the generation of a large amount of wastewater with a high organic content, and the generation of a large quantity of solid wastes and air pollution. In terms of waste transportation, we propose a multiobjective programming model for managing business environmental risk in a crude palm oil manufacture which gives the best possible configuration of waste management facilities and allocates wastes to these facilities. Then we develop an interactive approach for tackling logistics and environmental risk production planning problem for the crude palm oil industry.

    Full Text Available In a globalized era it is not enough to have a professional qualification to ensure economic and professional success. The academic background of professionals must be adequate to face challenges and solve problems of a globalized and dynamic world. Civil engineers face many complications when seeking an international career. There are many differences within the profession globally such as: resources, workforce, climate, language, culture, philosophies, regulations, etc. which raise the entry barriers to fully practice as a civil engineer. The International accreditations play a major role as the first evidence of the civil engineer technical proficiency. These assure the quality of the higher education curricula and add value to the human capital on an international context. Despite the fact that many Mexican Universities have academic programs which have international accreditations, civil engineer graduates cannot easily work across borders. This paper describes the impact that international accreditation has for civil engineers when seeking an international career.

    2010-07-01

    Crude oil is a complex mixture of hydrocarbons which consists of aromatics, paraffins, naphthenics, resins asphaltenes, etc. When the temperature of crude oil is reduced, the heavy components, like paraffin, will precipitate and deposit on the pipe internal wall in the form of a wax-oil gel. The gel deposit consists of wax crystals that trap some amount of oil. As the temperature gets cooler, more wax will precipitate and the thickness of the wax gel will increase, causing gradual solidification of the crude and eventually the oil stop moving inside the offshore pipeline. Crude oil may not be able to be re-mobilized during re-startup. The effective diameter will be reduced with wax deposition, resulting in several problems, for example, higher pressure drop which means additional pumping energy costs, poor oil quality, use of chemical components like precipitation inhibitors or flowing facilitators, equipment failure, risk of leakage, clogging of the ducts and process equipment. Wax deposition problems can become so sever that the whole pipeline can be completely blocked. It would cost millions of dollars to remediate an offshore pipeline that is blocked by wax. Wax solubility decreases drastically with decreasing temperature. At low temperatures, as encountered in deep water production, is easy to wax precipitate. The highest temperature below which the paraffins begins to precipitate as wax crystals is defined as wax appearance temperature (WAT). Deposition process is a complex free surface problem involving thermodynamics, fluid dynamics, mass and heat transfer. In this work, a numerical analysis of wax deposition by molecular diffusion and shear dispersion mechanisms in crude oil pipeline is studied. Diffusion flux of wax toward the wall is estimated by Fick's law of diffusion, in similar way the shear dispersion; wax concentration gradient at the solid-liquid interface is obtained by the volume fraction conservation equation; and since the wax deposition

    The horse was domesticated only 5.5 KYA, thousands of years after dogs, cattle, pigs, sheep, and goats. The horse nonetheless represents the domestic animal that most impacted human history; providing us with rapid transportation, which has considerably changed the speed and magnitude of the circulation of goods and people, as well as their cultures and diseases. By revolutionizing warfare and agriculture, horses also deeply influenced the politico-economic trajectory of human societies. Reciprocally, human activities have circled back on the recent evolution of the horse, by creating hundreds of domestic breeds through selective programs, while leading all wild populations to near extinction. Despite being tightly associated with humans, several aspects in the evolution of the domestic horse remain controversial. Here, we review recent advances in comparative genomics and paleogenomics that helped advance our understanding of the genetic foundation of domestic horses.

    The aim of the study was to evaluate overall dry matter, organic matter, crude protein, crude fat and gross energy digestibility of a feline commercial raw diet and a homemade raw diet compared with a canned, heat-processed diet. Six domestic shorthair kittens (20-28 weeks old) were fed three different diets in a Latin square crossover design. Diet A was a commercially available, canned, heat-processed diet. Diet B was a complete commercial, prefrozen, raw diet (commercial raw), and diet C was a raw diet supplement mixed with ground raw meat obtained locally (homemade raw). Both diets A and B were formulated to meet nutritional profile levels for cats at all life stages. Kittens were given specific diet amounts to maintain a 2-4% weight increase per week. Food was measured before and after feedings to determine the amount eaten, and all feces were collected, weighed and frozen prior to submission. Composite food samples and all feces were submitted to a national laboratory for proximate analysis of crude protein, crude fiber, ash, crude fat, moisture and caloric density. Significantly higher digestibility of dry matter (P raw diets compared with the heat-processed diets. This difference resulted in significantly less fecal matter (P raw diets compared with a heat-processed diet. Digestibility differences could have been due to variance in dietary protein, fat and carbohydrate concentrations between the diets, variance in dietary ingredients or quality, alterations in protein structure secondary to heat processing, as well as alterations in gastrointestinal flora. Future research examining digestibility in diets with the same macronutrient proportions and ingredients, and mechanisms for any differences, is warranted. © The Author(s) 2015.

    A new technology to convert extra heavy crude oil into transportable upgraded crude has been developed. A water/oil emulsion composed of steam and catalyst precursors is introduced in the feed which then generates unsupported dispersed catalyst in situ under thermal decomposition. The aim of this paper is to characterize the particles. The study was conducted in a laboratory and on a pilot scale on three different vacuum residues using high resolution transmission electron microscopy and a transmission electron microscope. Results showed that the particles were formed by oxides and inorganic sulphur based in transition metals and their sizes ranged between 5 and 120 nm; in addition, good dispersion was observed. This study demonstrated that the process involved in the generation of dispersed catalyst is extremely complex and showed that further work with heavy crude oils and its residua is required to understand the mechanisms involved.

    Rheological properties of Buchan crude oil-water interfaces have been determined using a biconical bob rheometer. The effects of temperature and the presence of surface-active demulsifiers on film characteristics have been evaluated. Free oscillation and creep modes have been used, depending on the relative viscoelastic behaviour of the films. Film ageing is particularly significant, whilst temperature and the nature and concentration of any demulsification chemicals also contribute significantly. Further detailed understanding of interfacial film rheology is considered to be desirable for a complete appreciation of the stability of water-in-crude oil emulsions

    The crude oil spot market declined after events in Iran precipitated stockpiling, while Iranian production cutbacks were smaller than anticipated. A growing spot market is affecting world oil prices with spot prices of $40 to $50 a barrel recorded during early November 1979. Larger stockpiles, however, will compensate for the projected supply cuts and a glut of residual fuels has helped to push prices back down. Some analysts feel that increased Saudi Arabian production is the key supply factor, while others question whether the Iranian cutback was directly ordered by the Ayatollah Khomeini.

    Reports that the most important feature of the partial combustion cracking (PCC) process is its ability to convert heavy petroleum fractions to light olefins with minimum residue. Presents diagram of the PCC process; graph of feedstock cost vs. return on investment (ROI); and tables with average ethylene yields, cracking yields, and PCC vs. LPG and naphtha cracking. Finds that the 10% difference in capital between the PCC and the naphtha feed case is due mainly to the cost of the acid gas and sulfur handling sections required for the PCC, but not for a naphtha cracker. The very favorable ROI and ethylene costs are due to the relative difference in feedstock pricing. Sensitivity of ROI to changes in feedstock was also studied for the PCC cases. The ratio of cost of high-sulfur fuel oil (HSFO) to average crude price is used to indicate the substantial effect of feedstock price on the attractiveness of the project. Concludes that with HSFO at 85 to 100% of crude value, the PCC represents an excellent investment for future ethylene needs.

    Domesticated animals play an important role in the life of humanity. All these domesticated animals undergo same process, first domesticated from wild animals, then after long time natural and artificial selection, formed various breeds that adapted to the local environment and human needs. In this process, domestication, natural and artificial selection will leave the selection signal in the genome. The research on these selection signals can find functional genes directly, is one of the most important strategies in screening functional genes. The current studies of selection signal have been performed in pigs, chickens, cattle, sheep, goats, dogs and other domestic animals, and found a great deal of functional genes. This paper provided an overview of the types and the detected methods of selection signal, and outlined researches of selection signal in domestic animals, and discussed the key issues in selection signal analysis and its prospects.

    The Phillips Petroleum International Corporation Asia (PPICA) Xijiang Field Development Project is a unique project resulting in the production of a waxy crude oil. The crude oil is produced on two platforms feeding a final production unit located on an FPSO (Floating Production, Storage and Off-loading) vessel located between the platforms. The crude from these two fields contains a high concentration of wax and has a relatively high pour point temperature. The crude composition and oil properties are listed in two tables. Special consideration was needed with respect to operating temperatures, start-up and shutdown procedures.

    Full Text Available This paper analyzes a consumption scheduling mechanism for domestic appliances within a home area network. The aim of the proposed scheduling is to minimize the total energy price paid by the consumer and to reduce power peaks in order to achieve a balanced daily load schedule. An exact and computationally efficient mixed-integer linear programming (MILP formulation of the problem is presented. This model is verified by several problem instances. Realistic scenarios based on the real price tariffs commercially available in the Czech Republic are calculated. The results obtained by solving the optimization problem are compared with a simulation of the ripple control service currently used by many domestic consumers in the Czech Republic.

    The work describes applications of polymers classified by petroleum end uses. Approximately 1200 literature references have been reviewed, 60% of which deal with applications in lubricants. Polymers are being used as additives for many phases of crude production, transportation, and processing. This includes improved drilling, flow behavior, recovery, desalting, and dehydration. For engine lubricants, the major use of polymers is still as viscosity modifiers. New types of viscosity index polymers are described. Most of the past 4 yr research effort in the lubricants area has dealt with the rheology of multigrade oils, particularly the temporary loss of viscosity under high shear rates and its effects on engine performance. In industrial lubricants, polymers increase load-carrying capacity; control wear, rust and foam; improve cold properties; reduce energy requirements and mist emissions; and modify surface active properties. Polymers are used in fuel products mainly to improve handling and stability debits. 253 references.

    The National Transportation Fuels Model was used to simulate a hypothetical increase in North Slope of Alaska crude oil production. The results show that the magnitude of production utilized depends in part on the ability of crude oil and refined products infrastructure in the contiguous United States to absorb and adjust to the additional supply. Decisions about expanding North Slope production can use the National Transportation Fuels Model take into account the effects on crude oil flows in the contiguous United States.

    Full Text Available The physicochemical properties of the Pechora Sea shelf oil and its chemical composition have been studied using the methods of refractometry, titrimetry, viscometry, rheometry and standard methods for the analysis of oil and petroleum products. The fractionation of oil is held at atmospheric pressure, some fractions boiling at the temperature below and above 211 °C have been received. Chemical structural-group composition of oil and its components has been investigated using a Fourier infrared (IR spectroscopy method. The density of oil has been obtained, it is equal to 24.2 API. The chemical composition analysis shows that water content in the investigated oil sample is about 0.03 % (by weight. The oil sample contains hydrocarbons (including alkanes, naphthenes, arenes and asphaltenes with resins; their content is equal to 89 and 10 % (by weight respectively. Alkane content is about 66 %, including alkanes of normal structure – about 37 %. The solidification temperature of oil sample is equal to –43 °C. This low temperature testifies obliquely low content of solid alkanes (paraffin. Bearing in mind the content of asphaltenes with resins we can refer the investigated oil sample to resinous oils. On the other hand spectral coefficient values (aromaticity quotient and aliphaticity quotient show that oil sample belongs to naphthenic oils. According to the data of Fourier IR spectroscopy contents of naphthenes and arenes are 5.9 and 17.8 % respectively. Thus, the obtained data of chemical structural-group composition of crude oil and its fractions indicate that this oil belongs to the heavy resinous naphthenic oils. The rheological parameters obtained at the shear deformation conditions characterize the crude oil as a visco-plastic medium.

    Violence against women is an urgent health priority in Iran. Designing effective programs for preventing and controlling the problem necessitates a thorough understanding of Iranian women and their perspectives regarding domestic violence. This study was aimed at exploring the domestic violence-related views of married women who were referred to health care facilities in Ahvaz, Iran. In this qualitative research, data were collected through four focus group discussions with 30 married women. All the discussions were recorded and transcribed, after which the data were classified separately. The main themes and subthemes were then manually derived from the data and analyzed. The five main themes identified were domestic violence against women in Ahvaz, behavioral influencing factors, nonbehavioral influencing factors, the necessity to empower women to prevent domestic violence, and recommendations for developing special training programs for Ahvazi women. Most of the participants were aware that domestic violence against women is a common occurrence in Iran. They were well aware of the definition of violence and expressed a belief that behavioral factors exert an important effect on the occurrence of the problem. They recommended the development of appropriate training programs that empower women to prevent the problem, the use of mass media to educate citizens about domestic violence, and the involvement of opinion leaders in eliminating the taboo against considering such violence a crime against Iranian women. Considering the views and ideas of women as consumers of educational services is a principle used to develop effective programs for preventing and controlling domestic violence. As indicated by the findings, the participants believe that empowering women must be treated as a priority in the Iranian health care system. However, they recommended differing approaches and methods of empowerment on the basis of their individual views and concerns.

    Little nutritional information has been collected from domestic cats fed raw meat diets. The objective of the present study was to evaluate differences in N metabolism of domestic cats fed raw beef-based diet (66 % crude protein (CP) and 20 % fat), bison-based diet (49 % CP and 39 % fat), elk-based diet (79 % CP and 6 % fat) and horse-based diet (60 % CP and 26 % fat). A total of eight intact adult female cats were fed to maintain body weight in a cross-over design. Daily food intake, faecal and urinary outputs, and N metabolism were measured. Dietary N was highly digestible (96.8 (SEM 0.7)) for all treatments. Urinary N accounted for a majority of total N excretion, and differences in total N excretion reflect differences in urinary N. Differences in N intake and N absorption were due to differences in CP levels among diets. N retention was similar to values reported in the literature for domestic cats fed purified and traditional extruded diets. Despite differences in protein concentrations and N intake, all raw meats tested maintained N metabolism.

  4. Crude oil prices: Speculation versus fundamentals

    Science.gov (United States)

    Kolodziej, Marek Krzysztof

    Beginning in 2004, the price of crude oil fluctuates rapidly over a wide range. Large and rapid price increases have recessionary consequences and dampen long-term infrastructural investment. I investigate whether price changes are driven by market fundamentals or speculation. With regard to market fundamentals, I revisit econometric evidence for the importance of demand shocks, as proxied by dry maritime cargo rates, on oil prices. When I eliminate transportation costs from both sides of the equation, disaggregate OPEC and non-OPEC production, and allow for more than one cointegrating relation, I find that previous specifications are inconsistent with arguments that demand shocks play an important role. Instead, results confirm the importance of OPEC supply shocks. I investigate two channels by which speculation may affect oil prices; the direct effect of trader behavior and changes in oil from a commodity to a financial asset. With regard to trader behavior, I find evidence that trader positions are required to explain the spread between spot and futures prices of crude oil on the New York Mercantile Exchange. The inclusion of trader positions clarifies the process of equilibrium error correction, such that there is bidirectional causality between prices and trader positions. This creates the possibility of speculative bubbles. With regard to oil as a commodity and/or financial asset, I use a Kalman Filter model to estimate the time-varying partial correlation between returns to investments in equity and oil markets. This correlation changes from negative to positive at the onset of the 2008 financial crisis. The low interest rates used to rescue the economy depress convenience yields, which reduces the benefits of holding oil as a commodity. Instead, oil becomes a financial asset (on net) as the oil market changed from contango to backwardation. Contradicting simple political narratives, my research suggests that both market fundamentals and speculation drive

  7. Thermal biology of domestic animals.

    Science.gov (United States)

    Collier, Robert J; Gebremedhin, Kifle G

    2015-01-01

    The thermal environment is the most important ecological factor determining the growth, development, and productivity of domestic animals. Routes of energy exchange (sensible heat and latent heat) between animals and their environment are greatly influenced by body weight, fat deposition, hair-coat properties, functional activity, and number of sweat glands, as well as the presence or absence of anatomical respiratory countercurrent heat exchange capability. Differences in these anatomical features across species have led to specialization of heat exchange. Thermal plasticity and degree of acclimation are critical factors determining the ability of animals to respond to environmental change. Increases in productive capability of domestic animals can compromise thermal acclimation and plasticity, requiring greater investments in housing systems that reduce variability of the thermal environment. The combination of steadily increasing metabolic heat production as domestic animal productivity increases and a rising world temperature poses ongoing and future challenges to maintaining health and well-being of domestic animals.

  8. The Effects of Commodities and Financial Markets on Crude Oil

    2017-01-01

    Full Text Available Investigating crude oil price volatility is crucial, because crude oil price certainly affects the economy through many channels. This study applies a Vector Auto Regression (VAR model to examine the impact of crude oil market on basic commodities, financial markets and industrial production. We find that the production in the US economy has an important effect on the crude oil prices. In addition we noticed a higher increase in crude oil price volatility after a large negative shock, contrary to a large positive one. Also, it was found that, in the short-run, oil price volatility is not influenced by short-run interest rates or industrial production. An adverse linkage between crude oil prices and industrial production has been proved confirming the economic theorists claiming that there is a close linkage between oil price shocks and economic activity. Finally, our findings indicate that there is Granger causality between crude oil and the endogenous variables used in the Granger causality framework.

    Full Text Available Two studies were conducted to evaluate the effects of crude glycerin on feed intake, performance, carcass characteristics, and total digestibility of Nellore bulls. In experiment 1, cattle (n = 30 were fed a control diet without crude glycerin and diets containing 7.5, 15, 22.5, and 30% crude glycerin, for 103 d. Animals were harvested and data of carcass characteristics were collected. In experiment 2, a digestibility trial was performed using indigestible acid detergent fiber (iADF as internal marker, and five rumen-cannulated steers. Both experiments were conducted as a randomized complete block design and data were analyzed using mixed procedures. In experiment 1 no differences were observed among treatments on dry matter intake, and performance variables. Regarding carcass characteristics, no effect was observed, except for carcass fat estimates, which were greater in treatments with crude glycerin. In experiment 2, crude glycerin promoted a decrease in digestibility of fibrous fractions NDF and HEM, and increased digestibility of crude protein by 6%. Although it caused negative effect on digestibility of fibrous fraction of diets, crude glycerin can be a good energy source for Nellore bulls, since no losses are observed on performance and carcass characteristics when animals are fed up to 30% of this by-product.

  10. Support groups for older victims of domestic violence.

    Wolf, R S

    2001-01-01

    A 1997 nationwide (US and Canada) search to identify support groups for older victims of domestic violence located 16 sponsored by domestic violence programs and 14 sponsored by aging services. Interviews with group leaders indicated more similarities than differences between the two types of sponsorship in group purpose, leadership, numbers served, content of support group sessions, and success in accomplishing goals. Resistance of elders to participate in a group experience was cited by leaders as a major barrier. Recommendations for future groups include insuring accessibility of meeting site; using a leader and co-leader, at least one of whom is older or familiar with aging issues; allocating resources for recruitment; and seeking a steady source of funding. A policy of collaboration among the state's domestic violence coalition, state unit on aging, adult protective services, and victim assistance program may help in promoting support group development and utilization.

    2010-01-01

    Objective. This study investigates whether or not domestic violence agencies are located in areas of need. Recent research indicates that community economic disadvantage is a risk factor for intimate partner violence, but related questions regarding the geographic location of social service agencies have not been investigated.Methods. Using Connecticut as a case study, we analyze the relationship of agency location and police-reported domestic violence incidents and assaults using OLS regression and correcting for spatial autocorrelation.Results. The presence of an agency within a town has no relationship with the rates of domestic violence. However, regional patterns are evident.Conclusion. Findings indicate that programs are not geographically mismatched with need, but neither are programs located in towns with higher rates of incidents or assaults. Future research and planning efforts should consider the geographic location of agencies.

  14. Effect of solid paraffin's on crude oil rheology

    Directory of Open Access Journals (Sweden)

    Šećerov-Sokolović Radmila M.

    2006-01-01

    Full Text Available Effect of solid paraffin on crude oil rheology was investigated. The experiments were carried out on model-crude oil at constant temperature 30°C. Medical paraffin malting point of 61 °C different concentration was dissolved in kerosene fraction. Concentration range of paraffin was from 1 to 32% weight. Shear stress strongly depends on paraffin's content only over high shear rate. Shear stress increases exponentially with increasing paraffin concentration for high shear rate. This dependence does not existed for real crude oil investigated in this paper.

    Fox, M C; Watkins, K L; Craig, W M; Stewart, T B; Clawson, A J; Southern, L L

    1988-04-01

    Twenty-five nongravid crossbred gilts (avg initial wt, 126 kg) were placed on either a high (38%) or a low (13%) crude protein (CP) diet and fed either at the rate of 1.82 kg/d or had ad libitum access to feed. In addition, a fifth group was pair-fed the 13% CP diet to the average intake of the gilts fed high CP ad libitum. The experimental period lasted 30 d. Corn-soybean meal diets were used and CP levels were varied by altering the corn:soybean meal ratio. Gain and gain/feed were reduced (P less than .01) in gilts fed 1.82 kg/d compared with the gilts fed ad libitum or pair-fed gilts. Gain (P less than .03) and feed intake (P less than .01) of gilts with ad libitum access to the 13% CP diet were higher than those of gilts with ad libitum access to the 38% CP diet. Gain/feed was not different (P greater than .10) between the two groups, however. Rate of gain and feed efficiency of gilts pair-fed the 13% CP diet were similar (P greater than .10) to those of gilts with ad libitum access to the 38% CP diet. Plasma total free amino acids, NH3 and total protein were not (P greater than .10) affected by treatment. Plasma urea-N and urinary total N, urea-N and orotic acid were increased (P less than .01) in gilts fed the high CP diet regardless of feed intake level. However, urinary NH3 was higher (P less than .01) in gilts fed the low-protein diet. These results indicate that excess dietary CP for nongravid gilts decreases gain and feed intake and has no effect on efficiency of feed utilization, but it increases plasma urea-N and urinary total N, urea-N and orotic acid.

    Thirty non-castrated male lambs with 20±2.3 kg average body weight (BW) were randomly assigned to five treatments consisted of different dietary concentrations of crude glycerin (CG; 0, 3, 6, 9 and 12% on DM basis) to evaluate the effects on performance, carcass and meat quality traits. A quadratic effect was observed for performance (P=0.04), final BW (P0.05) on carcass pH neither on shear-force, cooking loss and ether extract content in longissimus. The inclusion of CG tended to reduce the Zn content in meat (P=0.09). The data suggests that CG (36.2% of glycerol and 46.5% of crude fat) may be used in diets of finishing lambs with concentrations up to 3% without negative effects on performance and main carcass traits. Moreover, inclusion of CG seems to not affect quality and safety of meat for human consumption. Copyright © 2013 Elsevier Ltd. All rights reserved.

  2. The Therapeutic Efficacy of Domestic Violence Victim Interventions.

    Hackett, Shannon; McWhirter, Paula T; Lesher, Susan

    2016-04-01

    A meta-analysis on domestic violence interventions was conducted to determine overall effectiveness of mental health programs involving women and children in joint treatment. These interventions were further analyzed to determine whether outcomes are differentially affected based on the outcome measure employed. To date, no meta-analyses have been published on domestic violence victim intervention efficacy. The 17 investigations that met study criteria yielded findings indicating that domestic violence interventions have a large effect size (d = .812), which decreases to a medium effect size when compared to control groups (d = .518). Effect sizes were assessed to determine whether treatment differed according to the focus of the outcome measure employed: (a) external stress (behavioral problems, aggression, or alcohol use); (b) psychological adjustment (depression, anxiety, or happiness); (c) self-concept (self-esteem, perceived competence, or internal locus of control); (d) social adjustment (popularity, loneliness, or cooperativeness); (e) family relations (mother-child relations, affection, or quality of interaction); and (f) maltreatment events (reoccurrence of violence, return to partner). Results reveal that domestic violence interventions across all outcome categories yield effects in the medium to large range for both internalized and externalized symptomatology. Implications for greater awareness and support for domestic violence treatment and programming are discussed. © The Author(s) 2015.

    2014-02-14

    Crude oil is known to disrupt cardiac function in fish embryos. Large oil spills, such as the Deepwater Horizon (DWH) disaster that occurred in 2010 in the Gulf of Mexico, could severely affect fish at impacted spawning sites. The physiological mechanisms underlying such potential cardiotoxic effects remain unclear. Here, we show that crude oil samples collected from the DWH spill prolonged the action potential of isolated cardiomyocytes from juvenile bluefin and yellowfin tunas, through the blocking of the delayed rectifier potassium current (I(Kr)). Crude oil exposure also decreased calcium current (I(Ca)) and calcium cycling, which disrupted excitation-contraction coupling in cardiomyocytes. Our findings demonstrate a cardiotoxic mechanism by which crude oil affects the regulation of cellular excitability, with implications for life-threatening arrhythmias in vertebrates.

    Full Text Available Asphaltene precipitation and deposition are drastic issues in the petroleum industry. Monitoring the asphaltene stability in crude oil is still a serious problem and has been subject of many studies. To investigate crude oil stability by saturate, aromatic, resin and asphaltene (SARA analysis seven types of crudes with different components were used. The applied methods for SARA quantification are IP-143 and ASTM D893-69 and the colloidal instability index (CII is computed from the SARA values as well. In comparison between CII results, the values of oil compositions demonstrated that the stability of asphaltenes in crude oils is a phenomenon that is related to all these components and it cannot be associated only with one of them, individually.

    The challenge of processing heavy crudes and bitumen in a reliable and economical way was discussed. Many refiners use a conservative approach regarding the rate at which they use discounted crudes or depend upon capital-intensive upgrades to equipment. New strategies based on data-driven decisions are needed in order to obtain the greatest benefit from heavy feedstock. The feasibility of successfully processing more challenging feed can be estimated more accurately by better understanding the interactions between a particular feed and a particular crude unit. This presentation reviewed newly developed techniques that refiners can use to determine the feeds corrosion potential and the probability for this potential to manifest itself in a given crude unit. tabs., figs.

    2013-01-01

    Animal abuse and domestic violence are linked issues, and pet ownership is reported to play a crucial role in the choice to leave an abusive situation. Although veterinarians witness the effects of abuse and violence over the course of their careers, they have limited training regarding these issues. One mechanism for educating veterinary students while providing a service for victims of domestic violence is the creation of partnerships between domestic violence shelters and veterinary schools. These extracurricular programs can provide both care for pets belonging to victims of domestic violence and an educational platform for student participants. The goals of this study were to determine the prevalence and characteristics of domestic violence shelter partnerships (DVSPs) at North American veterinary teaching hospitals and to determine whether the presence of a DVSP was associated with increased awareness among veterinary students regarding animal abuse and domestic violence. Nine of 33 veterinary schools surveyed described a DVSP program. Students at schools with DVSPs associated with their veterinary teaching hospitals were significantly more likely to indicate that their awareness of the link between animal abuse and domestic violence had increased during veterinary school. Most veterinary students reported that they felt poorly prepared to handle domestic violence and animal abuse issues in the workplace. This study indicates that extracurricular DVSPs are a viable means of educating veterinary students regarding domestic violence and animal abuse. A need for improved education on these topics in veterinary schools across North America is identified.

  3. Aging Filipino Domestic Workers and the (In)Adequacy of Retirement Provisions in Canada.

    2017-03-01

    Although domestic work scholarship in Canada has focused primarily on the immigration/migration and labour experiences of domestic workers under the Foreign Domestic Movement and the Live-in-Caregiver Program, research is scarce on how these workers retire and consequently age in Canadian society. This article focuses on the aging experiences of retired Filipino domestic workers who, upon entering retirement, find themselves working in the secondary and/or underground economy while providing and receiving care from spouses, grandchildren, and local/transnational family members. Data were drawn from six qualitative, in-depth interviews with older Filipina domestic workers who discussed experiences of immigration, caring labour, retirement, and aging. Findings underscore (1) the poverty that older Filipino domestic workers encounter as they approach their retirement; (2) the necessity but insufficiency of the state's retirement provisions; (3) the need to find work in the unreported labour market; and (4) how caring labour is provided intergenerationally as a survival strategy.

    Full Text Available Colletotrichum gloeosporioides (Penz. Sacc. is a fungus that causes anthracnose disease in tropical fruit plants, resulting in damages of the fruit plants and low yield and quality of fruits. The use of chemical fungicides is common for management of this disease, but it also results in the development of fungal resistance to the chemicals. Therefore, this study aims to in vitro evaluate the efficacy of 14 crude leaf extracts against C. gloeosporioides. The results showed that Piper sarmentosum leaf extracts, using 80% of ethanol, methanol, and chloroform as solvents, were found to have very high antifungal activities. Crude methanol extract of P. sarmentosum leaves could effectively inhibit the growth of fungal mycelium (100%, followed by crude chloroform extract (81.85% and 80% ethanol extract (45.50%. Maximum inhibition of C. gloeosporioides spore germination could be obtained after application with crude methanol extract of P. sarmentosum leaves and crude chloroform extract of Mentha cordifolia leaves at 1.25 and 2.5%, respectively. In conclusion, crude extracts of P. sarmentosum leaves were found to be highly effective for inhibiting both C. gloeosporioides mycelium growth and spore germination, and they have a potential as the new natural fungicides for management of anthracnose disease.

    A significant proportion of reports of domestic violence against women involve multiple perpetrators. Although the number of perpetrators has been consistently identified as a measure of abuse severity, only a minority of studies of domestic violence examine the role of multiple offenders. Data on multi-perpetrator domestic violence (MDV) is frequently removed from analysis in domestic violence studies, or multi-perpetrator incidents are treated as single-perpetrator incidents. However, the available research links MDV to negative mental and physical health outcomes, intimate partner homicide, homelessness among women, and severe mental illness and suicidality. This article reviews the available prevalence data on MDV and draws together research on the contexts in which MDV takes place. It highlights two groups that are particularly vulnerable to MDV: (1) girls and women partnered to members of gangs and organized crime groups and (2) girls and women in some ethnic minority communities. While discussions of honor in relation to domestic violence are often racialized in Western media, this article highlights the cross-cultural role of masculine honor in collective violence against women in the working class and impoverished communities of majority cultures as well as in migrant and ethnic minority communities. It is clear that such complex forms of violence present a range of challenges for intervention and treatment and the article emphasizes the need for specialized and coordinated modes of investigation, support, and care.

    In order to examine the effects of crude oil and dispersed crude oil (DCO) on the swimming ability of puffer fish, Takifugu rubripes, the critical swimming speeds (U crit) of fish exposed to different concentrations of water-soluble fraction (WSF) of crude oil and DCO solution were determined in a swimming flume. WSF and DCO significantly affected the U crit of puffer fish (p puffer fish exposed to 136 mg L(-1) WSF and 56.4 mg L(-1) DCO decreased 48.7 % and 43.4 %, respectively. DCO was more toxic to puffer fish than WSF. These results suggested that crude oil and chemically dispersed oil could weaken the swimming ability of puffer fish.

    Domestic animal production in the arctic region is often thought to be based exclusively on reindeer herding. There are, however, regions in Northern Europe and Siberia having a long tradition in rearing breeds of cattle and horse adapted to the northers conditions also. The development of these arctic animal breeds has been largely founded on old tradition rather than on the programs of breeding organizations. As a result of the selection carried out by nature and man, the domestic animals of arctic regions express characteristics that are metabolic, structural, associated with reproductive physiology and conducive to the adaptation to arctic conditions.

    One in four women presenting to Emergency Departments in Australia have experienced domestic violence in their lives but there are no specialist services for victims of domestic violence in the state of New South Wales, population of 7.25 million. Fundamental forensic medical and nursing skills developed for the comprehensive assessment of complainants of sexual assault were utilised in the examination of victims of domestic violence in a trial project at Nepean Hospital, Sydney. The project was then reviewed via a series of qualitative patient and police interviews along with an analysis of court outcomes. Assessment by specialists in forensic documentation and interpretation of injuries with the provision of balanced expert opinions for court purposes can result in a number of benefits for the victims and the criminal justice system, including an increase in the rate of successful prosecutions.

  13. Estimation of evaporative losses during storage of crude oil and petroleum products

    2013-01-01

    Full Text Available Storage of crude oil and petroleum products inevitably leads to evaporative losses. Those losses are important for the industrial plants mass balances, as well as for the environmental protection. In this paper, estimation of evaporative losses was performed using software program TANKS 409d which was developed by the Agency for Environmental Protection of the United States - US EPA. Emissions were estimated for the following types of storage tanks: fixed conical roof tank, fixed dome roof tank, external floating roof tank, internal floating roof tank and domed external floating roof tank. Obtained results show quantities of evaporated losses per tone of stored liquid. Crude oil fixed roof storage tank losses are cca 0.5 kg per tone of crude oil. For floating roof, crude oil losses are 0.001 kg/t. Fuel oil (diesel fuel and heating oil have the smallest evaporation losses, which are in order of magnitude 10-3 kg/tone. Liquids with higher Reid Vapour Pressure have very high evaporative losses for tanks with fixed roof, up to 2.07 kg/tone. In case of external floating roof tank, losses are 0.32 kg/tone. The smallest losses are for internal floating roof tank and domed external floating roof tank: 0.072 and 0.044, respectively. Finally, it can be concluded that the liquid with low volatility of low BTEX amount can be stored in tanks with fixed roof. In this case, the prevailing economic aspect, because the total amount of evaporative loss does not significantly affect the environment. On the other hand, storage of volatile derivatives with high levels of BTEX is not justified from the economic point of view or from the standpoint of the environment protection.

  14. On human self-domestication, psychiatry, and eugenics

    2007-10-01

    Full Text Available Abstract The hypothesis that anatomically modern homo sapiens could have undergone changes akin to those observed in domesticated animals has been contemplated in the biological sciences for at least 150 years. The idea had already plagued philosophers such as Rousseau, who considered the civilisation of man as going against human nature, and eventually "sparked over" to the medical sciences in the late 19th and early 20th century. At that time, human "self-domestication" appealed to psychiatry, because it served as a causal explanation for the alleged degeneration of the "erbgut" (genetic material of entire populations and the presumed increase of mental disorders. Consequently, Social Darwinists emphasised preventing procreation by people of "lower genetic value" and positively selecting favourable traits in others. Both tendencies culminated in euthanasia and breeding programs ("Lebensborn" during the Nazi regime in Germany. Whether or not domestication actually plays a role in some anatomical changes since the late Pleistocene period is, from a biological standpoint, contentious, and the currently resurrected debate depends, in part, on the definitional criteria applied. However, the example of human self-domestication may illustrate that scientific ideas, especially when dealing with human biology, are prone to misuse, particularly if "is" is confused with "ought", i.e., if moral principles are deduced from biological facts. Although such naturalistic fallacies appear to be banned, modern genetics may, at least in theory, pose similar ethical problems to medicine, including psychiatry. In times during which studies into the genetics of psychiatric disorders are scientifically more valued than studies into environmental causation of disorders (which is currently the case, the prospects of genetic therapy may be tempting to alter the human genome in patients, probably at costs that no-one can foresee. In the case of "self-domestication", it

  16. Analysis of crude oil vapor pressures at the U.S. Strategic Petroleum Reserve.

    Crude oil storage caverns at the U.S. Strategic Petroleum Reserve (SPR) are solution-mined from subsurface salt domes along the U.S. Gulf Coast. While these salt domes exhibit many attractive characteristics for large-volume, long-term storage of oil such as low cost for construction, low permeability for effective fluids containment, and secure location deep underground, they also present unique technical challenges for maintaining oil quality within delivery standards. The vapor pressures of the crude oils stored at SPR tend to increase with storage time due to the combined effects of geothermal heating and gas intrusion from the surrounding salt. This presents a problem for oil delivery offsite because high vapor-pressure oil may lead to excessive atmospheric emissions of hydrocarbon gases that present explosion hazards, health hazards, and handling problems at atmospheric pressure. Recognizing this potential hazard, the U.S. Department of Energy, owner and operator of the SPR, implemented a crude oil vapor pressure monitoring program that collects vapor pressure data for all the storage caverns. From these data, DOE evaluates the rate of change in vapor pressures of its oils in the SPR. Moreover, DOE implemented a vapor pressure mitigation program in which the oils are degassed periodically and will be cooled immediately prior to delivery in order to reduce the vapor pressure to safe handling levels. The work described in this report evaluates the entire database since its origin in 1993, and determines the current levels of vapor pressure around the SPR, as well as the rate of change for purposes of optimizing both the mitigation program and meeting safe delivery standards. Generally, the rate of vapor pressure increase appears to be lower in this analysis than reported in the past and, problematic gas intrusion seems to be limited to just a few caverns. This being said, much of the current SPR inventory exceeds vapor pressure delivery guidelines and must be

    Many victims of domestic violence do not seek recourse to the needed medical and legal services. The aim of this study was to determine the difficulties faced by and experiences of female survivors of domestic violence during their medical and legal proceedings. We designed our study using a qualitative approach to understand the experiences of survivors during the legal process as well as their feelings and attitudes towards domestic violence through in-depth interviews. The data obtained from the participants were analyzed and synthesized using a thematic analysis procedure. Most of our participants reported different types of domestic violence, citing feelings of fear and loneliness during these experiences. They reported feeling dissatisfied with their complaints being ignored by the police and the perpetrators remaining unpunished. They complained of the complex procedures and negligence of staff in health-care centers such as hospitals, and they reported being shifted to several different places. We believe that an assessment of such female survivors in terms of specific standards set by specialists will help make improvements to the legal process. Education programs should be organized for professionals dealing with survivors of domestic violence. Special health-care services with fast proceedings must be established in health-care centers.

    This article exposes the conditions among children who are forced by their poor families to assume domestic work in households in Kenya. It is an accepted practice for parents to place daughters in households to help with housework and baby-sitting. The Sinaga Women and Child Labor Resource Center in Nairobi finds this exploitative and part of a wider practice that institutionalizes violence against women. The Center was established in 1995 to challenge the practice of child domestic labor. The Center's research reveals that child domestic workers tend to come from large, poor, and rural families or from urban slums. Wages are low or exchanged for shoes, clothes, and food. The hours of work are long. Mistreatment may include sexual molestation by male household members, beatings, verbal abuse, and mistrust. There is little recourse. Complaints from child workers or others outside the household can result in further mistreatment. Action against mistreatment is complicated by the prevailing image of activists as frustrated women with vendettas against men. The Center focuses on rehabilitation, literacy training, marketable skill development, and awareness creation. Counseling includes parents, children, and employers. Public awareness campaigns have resulted in employer referrals of youth workers for training. Other groups are joining the effort to improve conditions for child domestic workers.

  3. An Improved CO2-Crude Oil Minimum Miscibility Pressure Correlation

    2015-01-01

    Full Text Available Minimum miscibility pressure (MMP, which plays an important role in miscible flooding, is a key parameter in determining whether crude oil and gas are completely miscible. On the basis of 210 groups of CO2-crude oil system minimum miscibility pressure data, an improved CO2-crude oil system minimum miscibility pressure correlation was built by modified conjugate gradient method and global optimizing method. The new correlation is a uniform empirical correlation to calculate the MMP for both thin oil and heavy oil and is expressed as a function of reservoir temperature, C7+ molecular weight of crude oil, and mole fractions of volatile components (CH4 and N2 and intermediate components (CO2, H2S, and C2~C6 of crude oil. Compared to the eleven most popular and relatively high-accuracy CO2-oil system MMP correlations in the previous literature by other nine groups of CO2-oil MMP experimental data, which have not been used to develop the new correlation, it is found that the new empirical correlation provides the best reproduction of the nine groups of CO2-oil MMP experimental data with a percentage average absolute relative error (%AARE of 8% and a percentage maximum absolute relative error (%MARE of 21%, respectively.

    Crude oil does not freeze, but a freezing point is often used to describe the fluidness of crude oil, which is the highest temperature at which oil will stop flowing under specific test conditions. The freezing point of numerous samples of crude oil from the Tarim and the Junggar basins in China was measured. The freezing point is positively related to wax content for the Tarim basin samples, but negatively related to the content of resin and asphaltene. However, there are no obvious relationships between freezing point and wax, resin and asphaltene content for the Junggar samples. The results suggest that the freezing point of crude oil is mainly controlled by wax content if the wax content is not too low. Flow improvers affect the growth, modify the structure, and prevent the interlocking of wax crystals, thus enhancing the flow properties of crude oil. But when wax content is low, other factors will influence fluidness, such as the quantity and types of aromatics and heterocyclic compounds.

  5. Molecular Mechanisms of Crude Oil Developmental Toxicity in Fish.

    2017-07-01

    With major oil spills in Korea, the United States, and China in the past decade, there has been a dramatic increase in the number of studies characterizing the developmental toxicity of crude oil and its associated polycyclic aromatic compounds (PACs). The use of model fish species with associated tools for genetic manipulation, combined with high throughput genomics techniques in nonmodel fish species, has led to significant advances in understanding the cellular and molecular bases of functional and morphological defects arising from embryonic exposure to crude oil. Following from the identification of the developing heart as the primary target of crude oil developmental toxicity, studies on individual PACs have revealed a diversity of cardiotoxic mechanisms. For some PACs that are strong agonists of the aryl hydrocarbon receptor (AHR), defects in heart development arise in an AHR-dependent manner, which has been shown for potent organochlorine agonists, such as dioxins. However, crude oil contains a much larger fraction of compounds that have been found to interfere directly with cardiomyocyte physiology in an AHR-independent manner. By comparing the cellular and molecular responses to AHR-independent and AHR-dependent toxicity, this review focuses on new insights into heart-specific pathways underlying both acute and secondary adverse outcomes to crude oil exposure during fish development.

    Full Text Available The aim of this study was to determine the values of apparent digestible energy (DE and metabolizable energy (ME for crude glycerin derived of biodiesel based on pork fat for finishing pigs. The diets consisted of a basal diet and four levels of crude glycerin (0, 5, 10 and 15%. Twelve pigs were housed individually in metabolic cages and after seven days of adaptation, total collections of urine and feces for four consecutive days were performed. Gross energy (GE of crude glycerin, diets, urine and fecal samples from each animal was determined. The crude glycerin used in this experiment presented 74.74% glycerin and 6,500 kcal kg-1 gross energy. The values of digestible energy (DE and metabolizable energy (ME were estimated by difference in the DE, and content of the basal diet was subtracted from the test diets containing the ingredient. The amount of GE, DE and ME for finishing pigs was 6,500, 5,839 and 5,509 kcal kg-1, respectively, with a coefficient of 91.0% of DE and 94.0% of ME. The energy of crude glycerin is based on the levels of fatty acids and GE depends on the concentration of fatty acids and glycerin, ME being a percentage of GE averaging is 84.75%.

    Adsorption and desorption of a North Sea crude oil to silica and calcium carbonate surfaces were studied by a quartz crystal microbalance, while the bare surfaces and adsorbed oil layers were characterized by atomic force microscopy and contact angle measurements. Water contact angles were measured...... on the bare surfaces, surfaces with an adsorbed oil layer, and surfaces after being exposed to aqueous salt solutions. This showed that the silica surface became more hydrophobic after oil adsorption, while the wettability of the calcium carbonate surface was not significantly changed by adsorption of an oil...... layer. A surface energy component analysis based on the acid base theory showed that oil adsorption on the surfaces depends upon apolar, acidic, and basic oil components of the crude oil and that the adsorbed oil components differ for adsorption to silica and calcium carbonate.

    Full Text Available This paper examines the performance of bivariate volatility models for the crude oil spot and future returns of the WTI type barrel prices. Besides the volatility of spot and future crude oil barrel returns time series, the hedge ratio strategy is examined through the hedge effectiveness. Thus this study shows hedge strategies built using methodologies applied in the variance modelling of returns of crude oil prices in the spot and future markets, and covariance between these two market returns, which correspond to the inputs of the hedge strategy shown in this work. From the studied models the bivariate GARCH in a Diagonal VECH and BEKK representations was chosen, using three different models for the mean: a bivariate autoregressive, a vector autoregressive and a vector error correction. The methodologies used here take into consideration the denial of assumptions of homoscedasticity and normality for the return distributions making them more realistic.

    Biodiesel is a valuable alternative to fossil fuels and many countries choose biodiesel as an unconventional energy source. A large number of investigations have been done on microalgae as a source of oil production. In recent years, wastewater pollutions have caused many ecological problems, and therefore, wastewater phycoremediation has attracted the international attention. This paper studied the cultivation of Chlorella vulgaris in a crude oil polluted environment for biodiesel production. Intended concentrations were 10 and 20gperliter (crude oil/water) at two times. The results showed that the growth of C. vulgaris was improved in wastewater and the maximum amount of dry mass and oil was produced at the highest concentration of crude oil (0.41g and 0.15g/l, respectively). In addition, dry mass and oil yield of the microalga were significantly enhanced by increasing the experiment duration. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Full Text Available An experimental study was undertaken to assess the efficiency of Pseudomonas aeruginosa, Bacillus subtilis, and Acinetobacter lwoffi isolated from petroleum contaminated water and soil samples to degrade crude oil, separately and in a mixed bacterial consortium. Capillary gas chromatography was used for testing the effect of those bacterial species on the biodegradation of crude oil. Individual bacterial cultures showed less growth and degradation than did the mixed bacterial consortium. At temperature 22°C, the mixed bacterial consortium degraded a maximum of 88.5% of Egyptian crude oil after 28 days of incubation. This was followed by 77.8% by Pseudomonas aeruginosa, 76.7% by Bacillus subtilis, and 74.3% by Acinetobacter lwoffi. The results demonstrated that the selected bacterial isolates could be effective in biodegradation of oil spills individually and showed better biodegradation abilities when they are used together in mixed consortium.

    Full Text Available Purification of crude biodiesel is mandatory for the fuel to meet the strict international standard specifications for biodiesel. Therefore, this paper carefully analyzed recently published literatures which deal with the purification of biodiesel. As such, dry washing technologies and the most recent membrane biodiesel purification process have been thoroughly examined. Although purification of biodiesel using dry washing process involving magnesol and ion exchange resins provides high-quality biodiesel fuel, considerable amount of spent absorbents is recorded, besides the skeletal knowledge on its operating process. Further, recent findings have shown that biodiesel purification using membrane technique could offer high-quality biodiesel fuel with less wastewater discharges. Thus, both researchers and industries are expected to benefit from the development of membrane technique in purifying crude biodiesel. As well biodiesel purification via membranes has been shown to be environmentally friendly. For these reasons, it is important to explore and exploit membrane technology to purify crude biodiesel.

    Crude tea polysaccharide (crude TPS) was prepared from instant green tea by ethanol precipitation followed by ultrafiltration membrane treatment and its effects on blood lipid, liver lipid, and fecal lipid levels were examined with Sprague-Dawley rats fed a high-fat diet. Although crude TPS showed no effects on the serum lipid levels, it suppressed the liver lipid accumulation and increased the fecal excretion of dietary fat. Then, the structural features of crude TPS were investigated. After separation of crude TPS by DEAE-cellulose and gel-filtration column chromatography, two kinds of neutral tea polysaccharides (NTPS-LP and NTPS-HH) and an acidic polysaccharide (ATPS-MH) were obtained. According to monosaccharide composition, methylation, and NMR analyses, NTPS-LP, NPTS-HH, and ATPS-MH were presumed to be starch, arabinogalactan with β-1,3-linked galactosyl backbone blanched at position 6 and with 1,5-linked arabinofuranosyl residues, and α-1,4-linked galacturonic acid backbone with arabinogalactan region, respectively.

  1. Measuring efficiency of international crude oil markets: A multifractality approach

    Science.gov (United States)

    Niere, H. M.

    2015-01-01

    The three major international crude oil markets are treated as complex systems and their multifractal properties are explored. The study covers daily prices of Brent crude, OPEC reference basket and West Texas Intermediate (WTI) crude from January 2, 2003 to January 2, 2014. A multifractal detrended fluctuation analysis (MFDFA) is employed to extract the generalized Hurst exponents in each of the time series. The generalized Hurst exponent is used to measure the degree of multifractality which in turn is used to quantify the efficiency of the three international crude oil markets. To identify whether the source of multifractality is long-range correlations or broad fat-tail distributions, shuffled data and surrogated data corresponding to each of the time series are generated. Shuffled data are obtained by randomizing the order of the price returns data. This will destroy any long-range correlation of the time series. Surrogated data is produced using the Fourier-Detrended Fluctuation Analysis (F-DFA). This is done by randomizing the phases of the price returns data in Fourier space. This will normalize the distribution of the time series. The study found that for the three crude oil markets, there is a strong dependence of the generalized Hurst exponents with respect to the order of fluctuations. This shows that the daily price time series of the markets under study have signs of multifractality. Using the degree of multifractality as a measure of efficiency, the results show that WTI is the most efficient while OPEC is the least efficient market. This implies that OPEC has the highest likelihood to be manipulated among the three markets. This reflects the fact that Brent and WTI is a very competitive market hence, it has a higher level of complexity compared against OPEC, which has a large monopoly power. Comparing with shuffled data and surrogated data, the findings suggest that for all the three crude oil markets, the multifractality is mainly due to long

  2. Liquid ultrasonic flow meters for crude oil measurement

    Energy Technology Data Exchange (ETDEWEB)

    Kalivoda, Raymond J.; Lunde, Per

    2005-07-01

    Liquid ultrasonic flow meters (LUFMs) are gaining popularity for the accurate measurement of petroleum products. In North America the first edition of the API standard ''Measurement of liquid hydrocarbons by ultrasonic flow meters using transit time technology'' was issued in February 2005. It addresses both refined petroleum products and crude oil applications. Its field of application is mainly custody transfer applications but it does provide general guidelines for the installation and operation of LUFM's other applications such as allocation, check meters and leak detection. As with all new technologies performance claims are at times exaggerated or misunderstood and application knowledge is limited. Since ultrasonic meters have no moving parts they appear to have fewer limitations than other liquid flow meters. Liquids ultrasonic flow meters, like turbine meters, are sensitive to fluid properties. It is increasingly more difficult to apply on high viscosity products then on lighter hydrocarbon products. Therefore application data or experience on the measurement of refined or light crude oil may not necessarily be transferred to measuring medium to heavy crude oils. Before better and more quantitative knowledge is available on how LUFMs react on different fluids, the arguments advocating reduced need for in-situ proving and increased dependency on laboratory flow calibration (e.g. using water instead of hydrocarbons) may be questionable. The present paper explores the accurate measurement of crude oil with liquid ultrasonic meters. It defines the unique characteristics of the different API grades of crude oils and how they can affect the accuracy of the liquid ultrasonic measurement. Flow testing results using a new LUFM design are discussed. The paper is intended to provide increased insight into the potentials and limitations of crude oil measurement using ultrasonic flow meters. (author) (tk)

  13. The influence of magnetic fields on crude oils viscosity

    The crystallization of paraffin causes serious problems in the process of transportation of petroleum. This phenomenon increases the crude oil viscosity and implies an organic resin accumulation on pipeline wall, resulting in a reduced flux area or totally blocked pipes. One of the most challenging tasks for pipeline maintenance is solving this problem at low cost. Therefore, a method that inhibits the crystallization of paraffin and reduces the viscosity of crude oil could have many useful applications within the petroleum industry. Recent studies showed that magnetic fields reduce the Wax Appearance Temperature (WAT) and the viscosity of paraffin-based crude oil. For better understanding of this discovery, a series of tests was performed. This paper will show the influence of a DC magnetic field on rheological proprieties of three crude oils with different paraffin concentrations: a crude oil sample with 11 % p/p of paraffin concentration (sample 1); a crude oil sample with 6 % p/p of paraffin concentration (sample 2); a mixture of paraffin plus light crude oil with a total of 11 % p/p of paraffin concentration. These samples were placed in an electromagnet that generates a magnetic field of 1.3 Tesla. The samples' temperatures were conditioned around their Wax Appearance Temperature (WAT), and they were exposed to the field. As the viscosity of crude oil is very sensitive to the changes in temperature, it was ensured that the temperature has remained constant throughout the process. The sample 1 revealed a considerable reduction of viscosity: its original viscosity was 66 cP before magnetic field exposure, after that its viscosity was reduced to 39 cP. The other samples showed the same viscosity, before and after the magnetic field exposure. Since the samples 1 and 3 have the same paraffin concentrations, the viscosity reduction is not due only to the presence of paraffin; there must be other factors responsible for the interaction of sample 1 with the

    2005-01-01

    Full Text Available The majority states in the world, as well as Serbia and Montenegro, took over the obligations from international law documents with regards to prevention, protection and prosecution of domestic violence. Over the last several years, in Serbia and Montenegro, there have been some positive steps regarding more decisive reaction on domestic violence, in the first place thanks to NGOs advocacy. However, the state involvement and contribution is still symbolic in comparison with obligations that international documents require from it. Having that in mind, authors try to explain the role and significance of international law for improving social responses on family violence. They also give systematic review of the most important demands that international law set up before the state. The main aim of the text is the analysis of the role that international law has in making state strategies in the field of domestic violence, as well as systematic review of existing international standards in this area which have to be taken into consideration in legislative, institutionalized and other reforms which are on going in Serbia and Montenegro.

  3. Artificial cloning of domestic animals.

    Science.gov (United States)

    Keefer, Carol L

    2015-07-21

    Domestic animals can be cloned using techniques such as embryo splitting and nuclear transfer to produce genetically identical individuals. Although embryo splitting is limited to the production of only a few identical individuals, nuclear transfer of donor nuclei into recipient oocytes, whose own nuclear DNA has been removed, can result in large numbers of identical individuals. Moreover, clones can be produced using donor cells from sterile animals, such as steers and geldings, and, unlike their genetic source, these clones are fertile. In reality, due to low efficiencies and the high costs of cloning domestic species, only a limited number of identical individuals are generally produced, and these clones are primarily used as breed stock. In addition to providing a means of rescuing and propagating valuable genetics, somatic cell nuclear transfer (SCNT) research has contributed knowledge that has led to the direct reprogramming of cells (e.g., to induce pluripotent stem cells) and a better understanding of epigenetic regulation during embryonic development. In this review, I provide a broad overview of the historical development of cloning in domestic animals, of its application to the propagation of livestock and transgenic animal production, and of its scientific promise for advancing basic research.

    1999-01-01

    Neuropsychological functioning was assessed in 39 males who had committed domestic violence (batterers) and compared to 63 nonviolent (both maritally discordant and satisfied) subjects recruited by advertisement. Subjects were subsequently divided into two groups (head injured, nonhead injured) and these groups were also contrasted as a function of batterer status. Tests were administered to assess for cognitive and behavioral functions, including executive dysfunction, hypothesized to be a factor contributing to propensity for violence. Questionnaires and structured clinical interviews were used to assess marital discord, emotional distress, and violent behaviors. Batterers differed from nonbatterers across several cognitive domains: executive, learning, memory, and verbal functioning. Batterers were reliably discriminated from nonbatterers based on three neuropsychological tasks: Digit Symbol, Recognition Memory Test-Words, Wisconsin Card Sorting Test. Neuropsychological performance was the strongest correlate of domestic violence of all clinical variables measured. However, the inclusion of two other variables, severity of emotional distress and history of head injury, together with the neuropsychological indices provided the strongest correlation with batterers status. Among batterers, neuropsychological performance did not vary as a function of head injury status, indicating that while prior head injury was correlated with batterer status, it was not the sole basis for their impairments. The findings suggest that current cognitive status, prior brain injury, childhood academic problems, as well as psychosocial influences, contribute along with coexisting emotional distress to a propensity for domestic violence.

    2015-07-01

    This study explored the suitability of the seahorse Hippocampus reidi (Ginsburg, 1933) for assessing biomarkers of genotoxic effects and its use as a sentinel organism to detect the effects of acute exposure to petroleum hydrocarbons. Fish were exposed to three concentrations of crude oil (10, 20 and 30 g/kg) for 96 h, and the activity of phase II biotransformation enzyme glutathione S-transferase (GST) was measured. In addition, we performed genotoxicity assays, such as comet assay, micronucleus (MN) test and nuclear abnormalities (NA) induction, on the erythrocytes of the fish species. Our results revealed that the inhibition of hepatic GST activity in H. reidi was dependent on increasing crude oil concentrations. In contrast, an increase in the damage index (DI) and MN frequency were observed with increased crude oil concentrations. These results indicate that the alkaline comet assay and micronucleus test were suitable and useful in the evaluation of the genotoxicity of crude oil, which could improve determinations of the impact of oil spills on fish populations. In addition, H. reidi is a promising "sentinel organism" to detect the genotoxic impact of petroleum hydrocarbons. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available The increase in global biodiesel production is originating a glycerol surplus, which has no defined destination. An alternative to overcome this problem is its use as energy source in animal feeding. In Brazil, Pacu (Piaractus mesopotamicus is one of the most farmed native fish species, whereas Silver catfish (Rhamdia quelen is suitable for production in subtropical region. Considering little knowledge about crude glycerol utilization in feeds for Neotropical fish species, it was evaluated the apparent digestibility coefficients (ADCs for energy of crude glycerol for P. mesopotamicus and R. quelen. The digestibility and digestible energy content of crude glycerol can be considered excellent even when compared to energy of common ingredients such as maize and wheat, presenting 0.97 and 0.89 of energy ADCs, and 15.2 and 13.95MJ kg-1 of digestible energy for Pacu and Silver catfish, respectively. In conclusion, crude glycerol is an energetic ingredient with good potential in Brazilian native fish diets.

    2014-11-01

    Carotenoid degradation products, known as norisoprenoids, are aroma-impact compounds in several plants. Pandan wangi is a common name of the shrub Pandanus amaryllifolius. The genus name 'Pandanus' is derived from the Indonesian name of the tree, pandan. In Indonesia, the leaves from the plant are used for several purposes, e.g., as natural colorants and flavor, and as traditional treatments. The aim of this study was to determine the cleavage of β-carotene and β-apo-8'-carotenal by carotenoid-cleavage enzymes isolated from pandan leaves, to investigate dependencies of the enzymatic activities on temperature and pH, to determine the enzymatic reaction products by using Headspace Solid Phase Microextraction Gas Chromatography/Mass Spectrophotometry (HS-SPME GC/MS), and to investigate the influence of heat treatment and addition of crude enzyme on formation of norisoprenoids. Crude enzymes from pandan leaves showed higher activity against β-carotene than β-apo-8'-carotenal. The optimum temperature of crude enzymes was 70°, while the optimum pH value was 6. We identified β-ionone as the major volatile reaction product from the incubations of two different carotenoid substrates, β-carotene and β-apo-8'-carotenal. Several treatments, e.g., heat treatment and addition of crude enzymes in pandan leaves contributed to the norisoprenoid content. Our findings revealed that the crude enzymes from pandan leaves with carotenoid-cleavage activity might provide a potential application, especially for biocatalysis, in natural-flavor industry.

    While neurobiological factors are known to play a role in human aggression, relatively few studies have examined neuropsychological contributions to propensity for violence. We previously demonstrated cognitive deficits among men who committed domestic violence (batterers) compared to non-violent controls. Batterers had deficits in verbal ability, learning and executive problem-solving ability. These findings led us to examine whether executive control problems involving impulsivity contribute to problems with behavioral control among batterers, and to further examine their deficits in verbal functioning. Batterers (n = 41) enrolled in a domestic violence program were compared to 20 non-violent men of similar age, education, and socioeconomic background on neuropsychological tests of executive functioning, including impulsivity. Questionnaires and structured clinical interviews were used to assess emotional distress, aggression and self-reported impulsivity. Batterers showed greater impulsivity compared to non-batterers on several neuropsychological measures. Yet, the severity of these deficits was relatively mild and not evident in all batterers. Consistent with our previous findings, significant verbal deficits were again observed among the batterers. These findings suggest that while impulsivity may be a factor associated with domestic violence, it probably is not the sole determinant of the strong relationship between cognitive functioning and batterer status that we previously observed. Both verbal expressive deficits and behavioral impulsivity appear to be relevant variables in predisposing men to domestic violence.

    People suffering from mental illness are increasingly referred to the domestic violence court. Yet the typical diversion programs available, including batterer's intervention programs, are inappropriate for those with serious mental illness. As a result, the Miami-Dade Domestic Violence Court has developed a new approach for dealing with this population that applies mental health court techniques in domestic violence court. This article will describe and discuss this pioneering model. It also will situate this model within the context of other problem-solving courts and discuss how the court uses principles and approaches of therapeutic jurisprudence. The paper presents some preliminary data that describe the social and legal characteristics of 20 defendants in the Domestic Violence Mental Health Court followed over a two year period between 2005 and 2007.

    Three experiments were conducted to determine the effects of dietary addition of crude glycerin on pellet production efficiency and to evaluate its effect on growth performance and digestibility in growing-finishing pigs. Three dietary treatments were created by addition of 0, 2.5, or 5% crude glycerin to barley-soybean meal-based diet, and 4 batches of each dietary treatment (2 each for grower and finisher diets) were prepared. In the manufacturing process, crude glycerin supplementation linearly increased the feeder speed and production rate (P glycerin in feed increased. A growth experiment was performed with 240 barrows (30 ± 1 kg initial BW) using a 2-phase feeding program over a 12-wk period with 4 pens per treatment and 20 pigs per pen. On the last day of the growth experiment, blood samples were collected to determine circulating glucose, fructosamine, and IGF-1 concentrations. Overall growth performance was not affected (P > 0.05) by dietary treatment, and there was no effect (P > 0.05) of dietary treatment on any plasma metabolite measured. A digestibility experiment involving 9 male pigs housed in metabolic cages was used to determine the coefficients of apparent fecal digestibility and N and mineral balances. Pigs were assigned to 1 of the 3 diets in each feeding period using a 3 × 3 Latin square arrangement of treatments (43 ± 3 and 74 ± 3 kg initial BW in the growing and finishing periods, respectively). In both feeding periods, fecal digestibility of OM and ether extract were affected by dietary treatment, increasing linearly (P glycerin levels. However, neither CP digestibility nor N retention was affected by the glycerin content in either the growing or finishing period. Digestibilities and balance of Ca and P showed opposite tendencies with the variations in crude glycerin content, which either decreased or increased depending on the feeding period. In conclusion, adding crude glycerin to the diet before pelleting improved feed mill production

  3. Crude-oil vs coal-oil processing comparison study. Final report

    Energy Technology Data Exchange (ETDEWEB)

    1979-11-01

    This study evaluates three refinery schemes that have been developed for the processing of H-Coal liquids. The refinery processing employed for the naphtha and lighter components of the H-Coal liquid is essentially the same for all three schemes. It is in the processing of the H-Coal distillate product that refinery variations occur, and these differences are outlined: hydrotreating of the middle coal distillate to produce a No. 2 fuel oil equivalent product; hydrocracking of the total coal distillate to produce more gasoline and higher quality distillate fuel; and hydrotreating of the light coal distillate to a No. 2 fuel oil equivalent, and hydrogenating the heavy coal distillate to upgrade feedstock to a fluid catalytic cracking (FCC) unit. To provide a perspective of the value of coal liquid relative to petroleum, a parallel set of petroleum refinery schemes, processing a 65/35 Light/Heavy Arabian crude oil blend, was developed: reduced crude desulfurization with FCC processing of the desulfurized VGO; reduced crude desulfurization with hydrocracking of the desulfurized VGO; solvent demetallization of the vacuum pitch with desulfurization and FCC processing of VGO and demetallized oil; and solvent demetallization of the vacuum pitch with hydrocracking of the VGO and demetallized oil. Various gasoline to distillate ratios were set as parameters in developing the best possible processing schemes. Linear programming techniques were used to select the optimal schemes at various product ratios. Applying the same product prices to all cases and subtracting operating costs and the capital change, a comparative feedstock value is calculated. This method places the various refinery schemes on a common basis and gives an appraisal of the relative value of the H-Coal liquid charge stock, based on new refinery facilities.

    Many studies have attributed the disproportionately high rate of domestic violence in Asian communities to Asian patriarchal "cultural norms" and the psychological and behavioral traits that these norms produce in individuals. This article seeks to expand the scope of domestic violence analysis beyond these individual and cultural frameworks, arguing that Asian domestic violence is also a product of larger scale, social systems of inequality. By examining the funding criteria of the Family Violence Prevention Services Administration (FVPSA) and the Quality-Adjusted Life Year (QALY) standard used by Robin Hood, my research shows how state and private organizations systematically devalue and underfund minority-targeted programs.

    Domestic violence homicides and suicides are significant causes of deaths among women in India. This study examined characteristics and motives of various types of domestic violence-related homicides and suicides (n = 100) in India using newspaper reports (2011-2012). The majority of victims were found to be young women, mostly killed by burning or strangulation methods. The most frequently reported motive was dowry demands followed by a history of domestic violence or harassment and family conflict. The findings highlight the need for stronger prevention/intervention programs in India to identify and intervene with women at high risk for being killed or committing suicide.

    Full Text Available BACKGROUND: Isodon rugosus is used traditionally in the management of hypertension, rheumatism, tooth-ache and pyrexia. Present study was arranged to investigate I. rugosus for phytoconstituents, phytotoxic and cytotoxic activities to explore its toxicological, pharmacological potentials and to rationalize its ethnomedicinal uses. Briefly, qualitative phytochemical analysis of the plant extracts were carried out for the existence of alkaloids, flavonoids, saponins, oils, glycosides, anthraquinones, terpenoids, sterols and tannins. Plant crude methanolic extract (Ir.Cr, its subsequent fractions; n-hexane (Ir.Hex, chloroform (Ir.Chf, ethyl acetate (Ir.EtAc, aqueous (Ir.Aq and saponins (Ir.Sp in different concentrations were tested for phytotoxic and cytotoxic activities using radish seeds and brine shrimps (Artemia salina respectively. The phytotoxic activity was determined by percent root length inhibition (RLI and percent seeds germination inhibition (SGI while the cytotoxicity was obtained with percent lethality of the brine shrimps. RESULTS: Ir.Cr was tested positive for the presence of alkaloids, glycosides, flavonoids, oils, terpenoids, saponins, tannins and anthraquinones. Among different fractions Ir.Sp, Ir.Chf, Ir.EtAc, and Ir.Cr were most effective causing 93.55, 89.32, 81.32 and 58.68% inhibition of seeds in phytotoxicity assay, with IC50 values of 0.1, 0.1, 0.1 and 52 μg/ml respectively. Similarly, among all the tested samples, Ir.Sp exhibited the highest phytotoxic effect causing 91.33% root length inhibition with IC50 of 0.1 μg/ml. Ir.Sp and Ir.Chf were most effective against brine shrimps showing 92.23 and 76.67% lethality with LC50 values of 10 and 12 μg/ml respectively. CONCLUSIONS: It may be inferred from the current investigations that I. rugosus contains different secondary metabolites and is a potential source for the isolation of natural anticancer and herbicidal drug molecules. Different fractions exhibited phytotoxic and

  7. Evolutionary genomics of dog domestication.

    2012-02-01

    We review the underlying principles and tools used in genomic studies of domestic dogs aimed at understanding the genetic changes that have occurred during domestication. We show that there are two principle modes of evolution within dogs. One primary mode that accounts for much of the remarkable diversity of dog breeds is the fixation of discrete mutations of large effect in individual lineages that are then crossed to various breed groupings. This transfer of mutations across the dog evolutionary tree leads to the appearance of high phenotypic diversity that in actuality reflects a small number of major genes. A second mechanism causing diversification involves the selective breeding of dogs within distinct phenotypic or functional groups, which enhances specific group attributes such as heading or tracking. Such progressive selection leads to a distinct genetic structure in evolutionary trees such that functional and phenotypic groups cluster genetically. We trace the origin of the nuclear genome in dogs based on haplotype-sharing analyses between dogs and gray wolves and show that contrary to previous mtDNA analyses, the nuclear genome of dogs derives primarily from Middle Eastern or European wolves, a result more consistent with the archeological record. Sequencing analysis of the IGF1 gene, which has been the target of size selection in small breeds, further supports this conclusion. Finally, we discuss how a black coat color mutation that evolved in dogs has transformed North American gray wolf populations, providing a first example of a mutation that appeared under domestication and selectively swept through a wild relative.

    Crude fish oil is one of essential fatty acid sources, which is found in Sardinella lemuru. This research aims to study the quality improvement of mudcrab(Scylla serrata) feed. Four feed formulations were designed by using completely randomized design, including P0 = trash fish + 1% tapioca starch; P1=trash fish + 2.0% crude fish oil + 1% tapioca starch;, P2= trash fish +4.0% crude fish oil + 1% tapioca starch; P3=trash fish + 6.0% crude fish oil + 1% tapioca starch; P4=trash fish +8.0% crude fish oil + 1% tapioca starch, respectively, which were carried out in quadruplicate. This study showed that feed formulation significantly affected crude protein, crude fiber, crude lipid, ash, organic matter and nitrogen free extract and energy of mudcrab. The P2 feed was the best formulation but had a slight different from P3 formulation.

    2011-03-01

    Dog domestication was probably started very early during the Upper paleolithic period (~35,000 BP), thus well before any other animal or plant domestication. This early process, probably unconscious, is called proto-domestication to distinguish it from the real domestication process that has been dated around 14,000 BC. Genomic DNA analyses have shown recently that domestication started in the Middle East and rapidly expanded into all human populations. Nowadays, the dog population is fragmented in several hundreds of breeds well characterized by their phenotypes that offer a unique spectrum of polymorphism. More recent studies detect genetic signatures that will be useful to highlight breed history as well as the impact of domestication at the DNA level. Copyright © 2011 Académie des sciences.

    Full Text Available In the contemporary world, despite the growing importance and scale of the use of renewable energy , conventional energy resources still play a huge role. The European Union countries are dependent on the oil imports and the their main supplier of crude oil and natural gas has been the Russian Federation. After the collapse of the Soviet Union , the Caspian Sea region has become an alternative to Russian energy resources. The Unit-ed States , European Union, China and many other countries have shown their interest about this region. Despite a relatively large oil and natural gas reserves, the export of the-se commodities to the West is still problematic. Based on the available data and infor-mation, the publication explores the issue of energy resources transport directions with a particular emphasis on the crude oil from the Caspian Sea region to Europe.

    A state-of-the-art review and assessment of storage effects on crude oil and product quality was undertaken through a literature search by computer accessing several data base sources. Pertinent citations from that literature search are tabulated for the years 1980 to the present. This 1990 revision supplements earlier reviews by Brinkman and others which covered stability publications through 1979 and an update in 1983 by Goetzinger and others that covered the period 1952--1982. For purposes of organization, citations are listed in the current revision chronologically starting with the earliest 1980 publications. The citations have also been divided according to primary subject matter. Consequently 11 sections appear including: alternate fuels, gasoline, distillate fuel, jet fuel, residual fuel, crude oil, biodegradation, analyses, reaction mechanisms, containment, and handling and storage. Each section contains a brief narrative followed by all the citations for that category.

    In order to detect presence and quantity of Roundup Ready (RR) soybean in crude oil extracted from soybean seed with a different percentage of GMO seed two extraction methods were used, CTAB and DNeasy Plant Mini Kit. The amplifications of lectin gene, used to check the presence of soybean DNA, were not achieved in all CTAB extracts of DNA, while commercial kit gave satisfactory results. Comparing actual and estimated GMO content between two extraction methods, root mean square deviation for kit is 0.208 and for CTAB is 2.127, clearly demonstrated superiority of kit over CTAB extraction. The results of quantification evidently showed that if the oil samples originate from soybean seed with varying percentage of RR, it is possible to monitor the GMO content at the first stage of processing crude oil.

    Ten crude oils from two recovery stages spanning 5-10-year interval of five productive wells in the Tarim Basin, northwest China were analyzed for their compositional modification during production process. Significant compositional changes in polar and nonpolar fractions between the previous oil samples and the latter ones were noted at both bulk and molecular level. The latter oil samples appear to contain more aromatic fraction and less asphaltenes and resin, and their gas chromatography (GC) data for whole oil show reduced alkanes with low molecular weight and enhanced high homologue relative to the previous oil samples. Compared with the oils collected from the previous recovery stage, the concentration of basic type of nitrogen-containing compounds and organic acids in oils from the latter recovery stage have a reducing trend, suggesting the occurrence of interaction between crude oil and reservoir rock.

    The oxidation-extraction desulfurization of Saudi Arabian crudes was conducted with hydrogen peroxide-acetic acid oxidation system. The selection of extractant, the optimization of oxidation-extraction conditions, and the exploration of desulfurization mechanism were studied. As DMF was used as the extractant, the optimal desulfurization rate of 35.11 % and oil recovery of 95 % were obtained at 70 °C with the molar ratio of peracetic acid to sulfur of 8:1, the molar ratio of acetic acid to hydrogen peroxide of 2:1 and the volume ratio of extractant to oil of 1:1. The desulfurization effect of different fractions in the treated Saudi Arabian crudes was found to obey the following order: gasoline-diesel fraction >VGO fraction >VR fraction, due to different types and structures of sulfur compounds. The oil quality was less affected and most sulfides were mainly extracted via DMF.

    This study presents the performance of wavelet multiple linear regression (WMLR) technique in daily crude oil forecasting. WMLR model was developed by integrating the discrete wavelet transform (DWT) and multiple linear regression (MLR) model. The original time series was decomposed to sub-time series with different scales by wavelet theory. Correlation analysis was conducted to assist in the selection of optimal decomposed components as inputs for the WMLR model. The daily WTI crude oil price series has been used in this study to test the prediction capability of the proposed model. The forecasting performance of WMLR model were also compared with regular multiple linear regression (MLR), Autoregressive Moving Average (ARIMA) and Generalized Autoregressive Conditional Heteroscedasticity (GARCH) using root mean square errors (RMSE) and mean absolute errors (MAE). Based on the experimental results, it appears that the WMLR model performs better than the other forecasting technique tested in this study.

    Full Text Available In this paper is investigated the process of crude oil and its individual fractions cracking in the molten metals medium to produce light petroleum products. Thermodynamic calculations demonstrate the possibility of using lead and tin including alloys thereof as the melt. The cracking of West Siberian crude oil is studied at temperatures 400-600 °C. It is detected that as the temperature increases there is increase of aromatic hydrocarbons and olefins content in gasoline while naphthenes, n- and i-paraffins content reduces. Optimal temperature for cracking in molten metals is ~500 °C. The use of a submerged nozzle increases the yield of light petroleum products by ~2%. The research octane number of gasoline produced is 82-87 points. It is determined that the yield of light petroleum products depending on the experimental conditions is increased from 46.9 to 55.1-61.3% wt.   

  7. Process Considerations in the Biodesulfurization of Crude Oil

    1998-10-20

    Biodesulfurization offers an attractive alternative to conventional hydrodesulfurization due to the mild operating conditions and reaction specificity afforded by the biocatalyst. The enzymatic pathway existing in Rhodococcus has been demonstrated to oxidatively desulfhrize the organic sulfbr occurring in dibenzothiophene while leaving the hydrocarbon intact. In order for biodesulfiization to realize commercial success, a variety of process considerations must be addressed including reaction rate, emulsion formation and breakage, biocatalyst recovery, and both gas and liquid mass transport. This study compares batch stirred to electro-spray bioreactors in the biodesulfurization of both model organics and actual crudes in terms of their operating costs, ability to make and break emulsions, ability to effect efficient reaction rates and enhance mass transport. Further, sulfim speciation in crude oil is assessed and compared to the sulfur specificity of currently available biocatalyst.

    Full Text Available Human trafficking is an occurrence that, even in our time, is present in alarming proportions, in its actuality and consequences. It is a phenomenon with a long history and has been qualified as a serious international problem and is the object of interest for a large number of international subjects. However, the key international document that defines this phenomenon is the Convention against Transnational Organized Crime from Palermo 2000; specifically its Protocol to Prevent, Suppress and Punish Trafficking in Persons, especially Women and Children. After its adoption, intensive actions were undertaken to regulate the phenomenon on the level of national legislature. It's done so in the local legislature too. According to the criminal law of the republic of Serbia, besides the concrete law against human trafficking, a number of other crimes are connected to human trafficking. This paper deals with the most important ones. The purpose of this paper is to review the legislature on the phenomenon in the domestic law, then the accordance of incrimination with international standards, as well as to indicate the need for further changes in domestic legislature.

    Objective The aim of the present study was to review and analyse academic literature and program evaluations to identify promising evidence for health system responses to domestic violence in Australia and internationally. Methods English-language literature published between January 2005 and March 2016 was retrieved from search results using the terms 'domestic violence' or 'intimate partner violence' in different combinations with other relevant terms, resulting in 1671 documents, of which 59 were systematic reviews. Electronic databases (Medline (Ovid), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Psycinfo, Social work Abstracts, Informit, Violence and Abuse Abstracts, Family Studies Abstracts, Cochrane Library of Systematic Reviews and EMBASE) were searched and narrative analysis undertaken. Results This review details the evidence base for the following interventions by health services responding to domestic violence: first-line responses, routine screening, risk assessment and safety planning, counselling with women, mother-child interventions, responses to perpetrators, child protection notifications, training and system-level responses. Conclusions There is growing evidence for the effectiveness of health service interventions to reduce the extent of harm caused by domestic violence. What is known about the topic? Domestic violence is a significant problem globally with enormous human, social and economic costs. Although women who have experienced abuse make extensive use of healthcare services, health services have lagged behind the policing, criminal justice and other human service domains in responding to domestic violence. What does this paper add? The present comprehensive review identifies best-practice health system responses to domestic violence. What are the implications for practitioners? Health systems can play a key role in identifying and responding to domestic violence for women who often do not access other services

    Full Text Available The objective of this study was to evaluate the effects of two levels of crude protein and five levels of electrolyte balance on the performance and egg-quality of laying Japanese quail. Six hundred 45-day-oldquails were distributed in a randomized-block design with a 5 × 2 factorial arrangement comprising ten treatments, five replicates, and 12 birds per experimental unit. The electrolyte balance levels were 50, 125, 200, 275, and 350 mEq kg–1of diet, and crude protein (CP levels were 210 and 240 g kg-1. The performance and egg-quality variables assessed were: feed intake, feed conversion, egg-laying percentage, egg weight and mass, and albumin, yolk and shell weight. There were no interactions among the studied factors. The electrolyte balance and crude protein levels did not significantly affect the performance variables. However, increased shell weight of eggs stored for seven days was observed at an electrolyte balance level of 200 mEq kg–1. With regard to the CP levels, increased egg weight was observed at 28 days at a level of 210 g kg-1, whereas increased albumin weight was observed at 35 days of storage at a level of 240 g kg-1. A tendency toward an increase in egg albumin weight during the storage period of 14 days was observed. Based on the findings of this study, it is recommended that the diet for Japanese quails in the laying phase be formulated with an electrolyte balance of 50 mEq kg–1and 240 g kg-1 of crude protein This diet did not have a negative effect on productive performance, and by increasing the weight of egg albumin, eggs can be stored for a longer duration, thus demonstrating an alternative method to increase the shelf life of eggs.

    Snake venoms are synthesized and stored in venom glands. Most venoms are complex mixtures of several proteins, peptides, enzymes, toxins and non-protein components. In the present study, we investigated the oxidative stress and apoptosis in rat liver cells provoked by Naja haje crude injection (LD50) after four hours. Wistar rats were randomly divided into two groups, the control group was intraperitoneally injected with saline solution while LD50-dose envenomed group was intraperitoneally injected with venom at a dose of 0.025 μg/kg of body weight. Animals were killed four hours after the injection. Lipid peroxidation, nitric oxide and glutathione levels were measured as oxidative markers in serum and liver homogenate. In addition, liver function parameters and activities of antioxidant enzymes were determined. N. haje crude venom (0.025 μg/kg of body weight) enhanced lipid peroxidation and nitric oxide production in both serum and liver with concomitant reduction in glutathione, catalase, glutathione reductase and glutathione-S-transferase activities. Superoxide dismutase and glutathione peroxidase activities were significantly increased in liver of envenomed rats. These findings were associated with apoptosis induction in the liver. In addition, N. haje crude venom caused hepatic injury as indicated by histopathological changes in the liver tissue with an elevation in total bilirubin, serum alanine aminotransferase, aspartate aminotransferase, γ-glutamyl transpeptidase, and alkaline phosphatase. Based on the present results, it can hypothesized that N. haje crude venom is a potent inducer of toxin-mediated hepatotoxicity associated with apoptosis in the liver.

  13. Exporting Alaskan North Slope crude oil: Benefits and costs

    Energy Technology Data Exchange (ETDEWEB)

    1994-06-01

    The Department of Energy study examines the effects of lifting the current prohibitions against the export of Alaskan North Slope (ANS) crude. The study concludes that permitting exports would benefit the US economy. First, lifting the ban would expand the markets in which ANS oil can be sold, thereby increasing its value. ANS oil producers, the States of California and Alaska, and some of their local governments all would benefit from increased revenues. Permitting exports also would generate new economic activity and employment in California and Alaska. The study concludes that these economic benefits would be achieved without increasing gasoline prices (either in California or in the nation as a whole). Lifting the export ban could have important implications for US maritime interests. The Merchant Marine Act of 1970 (known as the Jones Act) requires all inter-coastal shipments to be carried on vessels that are US-owned, US-crewed, and US-built. By limiting the shipment of ANS crude to US ports only, the export ban creates jobs for the seafarers and the builders of Jones Act vessels. Because the Jones Act does not apply to exports, however, lifting the ban without also changing US maritime law would jeopardize the jobs associated with the current fleet of Jones Act tankers. Therefore the report analyzes selected economic impacts of several maritime policy alternatives, including: Maintaining current law, which allows foreign tankers to carry oil where export is allowed; requiring exports of ANS crude to be carried on Jones Act vessels; and requiring exports of ANS crude to be carried on vessels that are US-owned and US-crewed, but not necessarily US-built. Under each of these options, lifting the export ban would generate economic benefits.

  15. Crude glycerol combustion: Particulate, acrolein, and other volatile organic emissions

    KAUST Repository

    Steinmetz, Scott

    2013-01-01

    Crude glycerol is an abundant by-product of biodiesel production. As volumes of this potential waste grow, there is increasing interest in developing new value added uses. One possible use, as a boiler fuel for process heating, offers added advantages of energy integration and fossil fuel substitution. However, challenges to the use of crude glycerol as a boiler fuel include its low energy density, high viscosity, and high autoignition temperature. We have previously shown that a refractory-lined, high swirl burner can overcome challenges related to flame ignition and stability. However, critical issues related to ash behavior and the possible formation of acrolein remained. The work presented here indicates that the presence of dissolved catalysts used during the esterification and transesterification processes results in extremely large amounts of inorganic species in the crude glycerol. For the fuels examined here, the result is a submicron fly ash comprised primarily of sodium carbonates, phosphates, and sulfates. These particles report to a well-developed accumulation mode (0.3-0.7 μm diameter), indicating extensive ash vaporization and particle formation via nucleation, condensation, and coagulation. Particle mass emissions were between 2 and 4 g/m3. These results indicate that glycerol containing soluble catalyst is not suitable as a boiler fuel. Fortunately, process improvements are currently addressing this issue. Additionally, acrolein is of concern due to its toxicity, and is known to be formed from the low temperature thermal decomposition of glycerol. Currently, there is no known reliable method for measuring acrolein in sources. Acrolein and emissions of other volatile organic compounds were characterized through the use of a SUMMA canister-based sampling method followed by GC-MS analysis designed for ambient measurements. Results indicate crude glycerol combustion produces relatively small amounts of acrolein (∼15 ppbv) and other volatile organic

  16. Superheroes and masterminds of plant domestication.

    Martínez-Ainsworth, Natalia E; Tenaillon, Maud I

    2016-01-01

    Domestication is one of the most fundamental changes in the evolution of human societies. The geographical origins of domesticated plants are inferred from archaeology, ecology and genetic data. Scenarios vary among species and include single, diffuse or multiple independent domestications. Cultivated plants present a panel of traits, the "domestication syndrome" that distinguish them from their wild relatives. It encompasses yield-, food usage-, and cultivation-related traits. Most genes underlying those traits are "masterminds" affecting the regulation of gene networks. Phenotypic convergence of domestication traits across species or within species between independently domesticated forms rarely coincides with convergence at the gene level. We review here current data/models that propose a protracted transition model for domestication and investigate the impact of mating system, life cycle and gene flow on the pace of domestication. Finally, we discuss the cost of domestication, pointing to the importance of characterizing adaptive functional variation in wild resources. Copyright © 2016 Académie des sciences.

  17. Germline modification of domestic animals.

    Tang, L; González, R; Dobrinski, I

    2015-01-01

    Genetically-modified domestic animal models are of increasing significance in biomedical research and agriculture. As authentic ES cells derived from domestic animals are not yet available, the prevailing approaches for engineering genetic modifications in those animals are pronuclear microinjection and somatic cell nuclear transfer (SCNT, also known as cloning). Both pronuclear microinjection and SCNT are inefficient, costly, and time-consuming. In animals produced by pronuclear microinjection, the exogenous transgene is usually inserted randomly into the genome, which results in highly variable expression patterns and levels in different founders. Therefore, significant efforts are required to generate and screen multiple founders to obtain animals with optimal transgene expression. For SCNT, specific genetic modifications (both gain-of-function and loss-of-function) can be engineered and carefully selected in the somatic cell nucleus before nuclear transfer. SCNT has been used to generate a variety of genetically modified animals such as goats, pigs, sheep and cattle; however, animals resulting from SCNT frequently suffer from developmental abnormalities associated with incomplete nuclear reprogramming. Other strategies to generate genetically-modified animals rely on the use of the spermatozoon as a natural vector to introduce genetic material into the female gamete. This sperm mediated DNA transfer (SMGT) combined with intracytoplasmatic sperm injection (ICSI) has relatively high efficiency and allows the insertion of large DNA fragments, which, in turn, enhance proper gene expression. An approach currently being developed to complement SCNT for producing genetically modified animals is germ cell transplantation using genetically modified male germline stem cells (GSCs). This approach relies on the ability of GSCs that are genetically modified in vitro to colonize the recipient testis and produce donor derived sperm upon transplantation. As the genetic change

    2014-11-01

    The role of organoclays in hydrocarbon removal during biodegradation was investigated in aqueous clay/oil microcosm experiments with a hydrocarbon degrading microorganism community. The clays used for this study were Na-montmorillonite and saponite. These two clays were treated with didecyldimethylammonium bromide to produce organoclays which were used in this study. The study indicated that clays with high cation exchange capacity (CEC) such as Na-montmorillonite produced an organomontmorillonite that was inhibitory to biodegradation of the crude oil hydrocarbons. Extensive hydrophobic interaction between the organic phase of the organoclay and the crude oil hydrocarbons is suggested to render the hydrocarbons unavailable for biodegradation. However, untreated Na-montmorillonite was stimulatory to biodegradation of the hydrocarbons and is believed to have done so because of its high surface area for the accumulation of microbes and nutrients making it easy for the microbes to access the nutrients. This study indicates that unlike unmodified montmorillonites, organomontmorillonite may not serve any useful purpose in the bioremediation of crude oil spill sites where hydrocarbon removal by biodegradation is desired within a rapid time period.

    Approximately 43 million people (about 14 percent of the U.S. population) rely on privately owned domestic wells as their source of drinking water. Unlike public water systems, which are regulated by the Safe Drinking Water Act, there is no comprehensive national program to ensure that the water from domestic wells is routinely tested and that is it safe to drink. A study published in 2009 from the National Water-Quality Assessment Program of the U.S. Geological Survey assessed water-quality conditions from 2,100 domestic wells within 48 states and reported that more than one in five (23 percent) of the sampled wells contained one or more contaminants at a concentration greater than a human-health benchmark. In addition, there are many activities such as resource extraction, climate change-induced drought, and changes in land use patterns that could potentially affect the quality of the ground water source for domestic wells. The Health Studies Branch (HSB) of the National Center for Environmental Health, Centers for Disease Control and Prevention, created a Clean Water for Health Program to help address domestic well concerns. The goals of this program are to identify emerging public health issues associated with using domestic wells for drinking water and develop plans to address these issues. As part of this effort, HSB in cooperation with the U.S. Geological Survey has created probability models to estimate the probability of arsenic occurring at various concentrations in domestic wells in the U.S. We will present preliminary results of the project, including estimates of the population supplied by domestic wells that is likely to have arsenic greater than 10 micrograms per liter. Nationwide, we estimate this to be just over 2 million people. Logistic regression model results showing probabilities of arsenic greater than the Maximum Contaminant Level for public supply wells of 10 micrograms per liter in domestic wells in the U.S., based on data for arsenic

    Nowadays, there is an increasing discussion among specialists about water use efficiency and the best measures to improve it. In Portugal, there have been a few attempts to expand the implementation of in situ water reuse projects. However, there is a lack of information about indoor water uses and how they are influenced by sociodemographic characteristics. There are several studies that investigate per capita global water usage, but the partitioning of this volume per domestic device and daily cycles is yet unknown. Identified as one of the key questions in sustainable building design, the water end-use is of primary importance to the design of hydraulic networks in buildings. In order to overcome this lack, a quantitative characterization of daily water uses for each domestic device was performed, based on a weekly monitoring program in fifty-two different dwellings in the northern region of Portugal (Vila Real, Valpaços and Oporto). For forty of them, each water usage of different domestic devices of each dwelling was recorded. At the same time, the remaining twelve dwellings were also monitored in order to register the volume of water consumed in each utilization of each domestic device. This paper presents the results of this complete monitoring program, using collected data to establish indoor water use patterns for each domestic device, aiming to support a more realistic approach to residential water use. The daily cycles in the different cities, where the monitoring program was performed, are also presented, in order to evaluate possible influences of sociodemographic characteristics. - Highlights: • This paper presents a method to find out the pattern of water use in dwellings. • The number of uses per person a day, by domestic device, is presented. • The volume spent per type of use by domestic device is presented. • The daily cycles per domestic device are presented. • Sociodemographic characteristics seem to affect the daily cycles.

    2010-07-01

    Heavy oils, extra-heavy oils and tar sands are major players for the future of energy. They represent a massive world resource, at least the size of conventional oils. They are found all over the world but Canada and Venezuela together account, by themselves, for more than half of world deposits. They share the same origin as the lighter conventional oils, but their geological fate drove them into thick, viscous tar-like crude oils. Most of them result from alteration processes mediated by microbial degradation. They are characterized by a low content of lighter cuts and a high content of impurities such as sulfur and nitrogen compounds and metals; so, their production is difficult and deployment of specific processes is required in order to enhance their transportability and to upgrade them into valuable products meeting market needs, and honouring environmental requirements. Although these resources are increasingly becoming commercially producible, less than 1% of total heavy crude oil deposits worldwide are under active development. The voluntarily wide scope of this volume encompasses geology, production, transportation, upgrading, economics and environmental issues of heavy oils. It does not pretend to be exhaustive, but to provide an authoritative view of this very important energy resource. Besides presenting the current status of knowledge and technology involved in exploiting heavy oils, the purpose is to provide an insight into technical, economic and environmental challenges that should be taken up in order to increase the efficiency of production and processing, and finally to give a prospective view of the emerging technologies which will contribute to releasing the immense potential reserves of heavy oil and tar deposits.

    Offender rehabilitation, pitting the rational ability of criminal justice against the seeming irrationality of criminal behavior, remains controversial. Psychology highlights the importance of emotions in mediating individual behavior. Borrowing from restorative justice as a more emotionally intelligent form of justice, this article examines the role of shame and guilt in a domestic violence offender treatment program. The emotions are differentiated and then activated, similar to the use of reintegrative shaming in restorative justice, to promote greater offender accountability and empathy. Using a two-group comparison of male domestic violence offenders, measurements were taken on three sets of scales in assessing the outcome of the shame transformation process. Statistically significant effects were found for self-esteem and empathetic concern. Findings and future research are discussed.

    This paper reviews the recent medical and legal literature in the field of spouse abuse. Domestic violence is a national phenomenon that directly affects victims of spouse abuse and indirectly conditions the children of the victims to accept violent behavior as normative. This paper characterizes the cycle of violence battered women encounter, describes their injury patterns, explores the dynamics of the abusive relationship, and discusses the factors that compel women to remain in such violent relationships. The second section describes many of the recent legislation designed to prevent spouse abuse. Next, this paper addresses the case law utilizing the "battered woman syndrome" as a defense for spousal homicide. The third section of the paper explores the often neglected topic of the battered husband.

  6. Daily Crude Oil Price Forecasting Using Hybridizing Wavelet and Artificial Neural Network Model

    Directory of Open Access Journals (Sweden)

    Ani Shabri

    2014-01-01

    Full Text Available A new method based on integrating discrete wavelet transform and artificial neural networks (WANN model for daily crude oil price forecasting is proposed. The discrete Mallat wavelet transform is used to decompose the crude price series into one approximation series and some details series (DS. The new series obtained by adding the effective one approximation series and DS component is then used as input into the ANN model to forecast crude oil price. The relative performance of WANN model was compared to regular ANN model for crude oil forecasting at lead times of 1 day for two main crude oil price series, West Texas Intermediate (WTI and Brent crude oil spot prices. In both cases, WANN model was found to provide more accurate crude oil prices forecasts than individual ANN model.

    2016-06-01

    Crude oil spills resulting from excavation, transportation and downstream processes can cause intensive damage to living organisms and result in changes in the microbial population of that environment. In this study, we used a pyrosequencing analysis to investigate changes in the microbial population of soils contaminated with crude oil. Crude oil contamination in soil resulted in the creation of a more homogenous population of microorganisms dominated by members of the Actinomycetales, Clostridiales and Bacillales (all belonging to Gram-positive bacteria) as well as Flavobacteriales, Pseudomonadales, Burkholderiales, Rhizobiales and Sphingomonadales (all belonging to Gram-negative bacteria). These changes in the biodiversity decreased the ratios of chemoheterotrophic bacteria at higher concentrations of crude oil contamination, with these being replaced by photoheterotrophic bacteria, mainly Rhodospirillales. Several of the dominant microbial orders in the crude oil contaminated soils are able to degrade crude oil hydrocarbons and therefore are potentially useful for remediation of crude oil in contaminated sites.

    2016-11-01

    In light of the importance of crude oil to the world's economy, it is not surprising that economists have devoted great efforts towards developing methods to forecast price and volatility levels. Crude oil is an important energy commodity to mankind. Several causes have made crude oil prices to be volatile such as economic, political and social. Hence, forecasting the crude oil prices is essential to avoid unforeseen circumstances towards economic activity. In this study, daily crude oil prices data was obtained from WTI dated 2nd January to 29th May 2015. We used Hidden Markov Model (HMM) and Forward-Backward Algorithm to forecasting the crude oil prices. In this study, the analyses were done using Maple software. Based on the study, we concluded that model (0 3 0) is able to produce accurate forecast based on a description of history patterns in crude oil prices.

  9. Getting domestication straight: ramosa1 in maize.

    Science.gov (United States)

    Dempewolf, Hannes

    2010-04-01

    Knowledge of the identities and characteristics of genes that govern the dramatic phenotypic differences between cultivated plants and their wild ancestors has greatly enhanced our understanding of the domestication process. In this issue of Molecular Ecology, Sigmon & Vollbrecht report the discovery of a new maize domestication gene, ramosa1, which encodes a putative transcription factor in the ramosa developmental pathway. Ramosa1 appears to be instrumental in determining the straightness of kernel rows on the maize cob. The key domestication alleles at ramosa1 are prevalent in landraces of maize. These results reinforce findings from previous studies of crop evolution by highlighting the importance of standing genetic variation and changes in transcriptional regulators in domestication. The evolutionary genetics of domestication also provides a framework for predicting the evolutionary response of organisms to strong human-induced selection pressures over limited time intervals.

    2017-01-01

    The world’s domestic cats carry patterns of sequence variation in their genome that reflect a history of domestication and breed development. A genetic assessment of 979 domestic cats and their wild progenitors—Felis silvestris silvestris (European wildcat), F. s. lybica (Near Eastern wildcat), F. s. ornata (central Asian wildcat), F. s. cafra (southern African wildcat), and F. s. bieti (Chinese desert cat)—indicated that each wild group represents a distinctive subspecies of Felis silvestris. Further analysis revealed that cats were domesticated in the Near East, probably coincident with agricultural village development in the Fertile Crescent. Domestic cats derive from at least five founders from across this region, whose descendants were transported across the world by human assistance. PMID:17600185

  12. Domestication and Genetics of Papaya: A Review

    Directory of Open Access Journals (Sweden)

    Mariana Chávez-Pesqueira

    2017-12-01

    Full Text Available A wealth of plant species used by humans for different purposes, but mainly as food, originated and domesticated in the Mesoamerican region. Papaya (Carica papaya is the third most cultivated tropical crop worldwide, and it has been hypothesized that Mesoamerica is the most likely center of its origin and domestication. In support of it, many wild populations of papaya occur throughout Mesoamerica and hence represent the gene pool of genetic variability for further evolution and future crop management. Despite its importance, a dearth of information exists regarding the status of wild populations of papaya, as compared to the extent of knowledge, and interest, on domesticated varieties. We review the evidence on the extant wild populations of papaya, as well as its origin and distribution. Also, we synthetize what is known on the domestication history of the species, including the domestication syndrome that distinguishes wild and domesticated papayas. Moreover, we make an account of the use of genetic markers to assess genetic diversity of wild and domesticated papaya, and discuss the importance of papaya as the first species with a transgenic cultivar to be released for human consumption, and one that has its complete genome sequenced. Evidence from different disciplines strongly suggest that papaya originated and was domesticated in Mesoamerica, and that wild populations in the region possess, still, high genetic diversity compared to the domesticated papaya. Finally, we outline papaya as an excellent model species for genomic studies that will help gain insight into the domestication process and improvement of papaya and other tropical crops.

  13. Domestic violence and child nutrition in Liberia.

    Sobkoviak, Rudina M; Yount, Kathryn M; Halim, Nafisa

    2012-01-01

    Domestic violence against women is endemic globally and is an important social problem in its own right. A compounding concern is the impact of domestic violence against mothers on the nutritional status of their children. Liberia is an apt setting to examine this understudied topic, given the poor nutritional status of young children, high rate of domestic violence against women, and prolonged period of conflict that included systematic sexual violence against women. We expected that maternal exposure to domestic violence would predict lower anthropometric z-scores and higher odds of stunting, wasting, and underweight in children less than five years. Using data from 2467 mother-child dyads in the 2007 Liberia Demographic and Health Survey (LDHS) undertaken between December 24, 2006 and April 19, 2007, we conducted descriptive and multivariate analyses to examine the total, unadjusted and adjusted associations of maternal exposure to domestic violence with these anthropometric measures in children. Maternal reports of sexual domestic violence in the prior year predicted lower adjusted z-scores for height-for-age and weight-for-height as well as higher odds of stunting and underweight. The findings underscore the needs to (1) enhance and enforce conventional and customary laws to prevent the occurrence of domestic violence; (2) treat maternal survivors of domestic violence and screen their children for nutritional deficits; (3) heighten awareness of the intergenerational implications especially of recent sexual domestic violence; and (4) clarify the biological and behavior pathways by which domestic violence may influence child growth, thereby mitigating early growth failure and its adverse implications into adulthood.

    2006-01-01

    Domestic violence affects women across all racial, national, social, and economic groups. In particular, immigrant and refugee families are at risk for domestic violence because of their migration history and differences in cultural values and norms. The Ahimsa for Safe Families Project is an innovative collaborative project that addresses domestic violence in immigrant and refugee communities in San Diego. The project is designed to increase awareness of domestic violence among Latino, Somali, and Vietnamese communities and to develop and implement culturally specific programs aimed at each community. Here the authors describe the Project's needs assessment and community dialogues that guided the development of specific interventions; present the lessons learned; and describe replicable, culturally specific prevention strategies utilized by the Project.

  16. Parallel domestication, convergent evolution and duplicated gene recruitment in allopolyploid cotton.

    Hovav, Ran; Chaudhary, Bhupendra; Udall, Joshua A; Flagel, Lex; Wendel, Jonathan F

    2008-07-01

    A putative advantage of allopolyploidy is the possibility of differential selection of duplicated (homeologous) genes originating from two different progenitor genomes. In this note we explore this hypothesis using a high throughput, SNP-specific microarray technology applied to seed trichomes (cotton) harvested from three developmental time points in wild and modern accessions of two independently domesticated cotton species, Gossypium hirsutum and G. barbadense. We show that homeolog expression ratios are dynamic both developmentally and over the several-thousand-year period encompassed by domestication and crop improvement, and that domestication increased the modulation of homeologous gene expression. In both species, D-genome expression was preferentially enhanced under human selection pressure, but for nonoverlapping sets of genes for the two independent domestication events. Our data suggest that human selection may have operated on different components of the fiber developmental genetic program in G. hirsutum and G. barbadense, leading to convergent rather than parallel genetic alterations and resulting morphology.

  17. Technical Proposal for Loading 3000 Gallon Crude Oil Samples from Field Terminal to Sandia Pressurized Tanker to Support US DOE/DOT Crude Oil Characterization Research Study

    Energy Technology Data Exchange (ETDEWEB)

    Lord, David; Allen, Raymond

    2016-10-01

    Sandia National Laboratories is seeking access to crude oil samples for a research project evaluating crude oil combustion properties in large-scale tests at Sandia National Laboratories in Albuquerque, NM. Samples must be collected from a source location and transported to Albuquerque in a tanker that complies with all applicable regulations for transportation of crude oil over public roadways. Moreover, the samples must not gain or lose any components, to include dissolved gases, from the point of loading through the time of combustion at the Sandia testing facility. In order to achieve this, Sandia designed and is currently procuring a custom tanker that utilizes water displacement in order to achieve these performance requirements. The water displacement procedure is modeled after the GPA 2174 standard “Obtaining Liquid Hydrocarbons Samples for Analysis by Gas Chromatography” (GPA 2014) that is used routinely by crude oil analytical laboratories for capturing and testing condensates and “live” crude oils, though it is practiced at the liter scale in most applications. The Sandia testing requires 3,000 gallons of crude. As such, the water displacement method will be upscaled and implemented in a custom tanker. This report describes the loading process for acquiring a ~3,000 gallon crude oil sample from commercial process piping containing single phase liquid crude oil at nominally 50-100 psig. This document contains a general description of the process (Section 2), detailed loading procedure (Section 3) and associated oil testing protocols (Section 4).

    Removal of vanadium from vanadyl (IV) meso-tetra-phenylporphyrin (VO-MTPP) and vanadyl (IV) octa-ethylporphyrin (VO-OEP) and metals removal from Ayacucho Venezuelan crude oil samples were performed using electrochemical techniques. According to cyclic voltammograms, a potential of - 2.3 V vs. Ag/AgNO{sub 3} (0.1 M), LiClO{sub 4} (0.1 M) in acetonitrile, was chosen for running electrolysis at platinum (Pt), graphite (G) and glassy carbon (GC) electrodes. Qualitative analysis was done by cyclic voltammetry (CV) and atomic absorption spectroscopy (AAS) while quantification was performed by AAS and inductively coupled plasma/atomic emission spectrometry (ICP/AES). Three stages (best results) of the study are reported: (a) when using commercial porphyrins; the best conditions for electrolysis were: tetrahydrofuran (THF)/20% methanol (MeOH)/1% perchloric acid (HClO{sub 4}) on GC, producing 84% hydro-demetalation (HDM) for VO-MTPP, and 78% HDM for VO-OEP; (b) when using extracts of crude oil; demetalation percentages, after 90 min of electrolysis, on graphite, and after 120 min of electrolysis on platinum, were 66.44% and 64.10% HDM respectively, no discrimination of metals under these conditions (c) from electrolysis in whole crude oil, quantitative analysis gave: vanadium (V) 31.2 mg/kg, iron (Fe) 65, 0 mg/kg and nickel (Ni) 6, 3 mg/kg, with charge efficiencies of V (7.5%), Fe (79.6%) and Ni (8.2%).

    The present study describes the analgesic effects of the crude extracts (hexane, methylene chloride and ethanol) obtained from the aerial parts of Miconia albicans (Melastomataceae) using the writhing test and the hot plate models for pain in mice. The extracts in hexane and methylene chloride, given orally, produced significant antinociception in the writhing test. On the other hand, none of the extracts had a significant effect on the hot plate test, a fact suggesting that the substances present in the extracts may rather have peripheral analgesic activity.

    Crude fiber was determined in a wide range of feed products by a method which specifies ceramic fiber as a filter medium instead of the more hazardous and difficult to obtain asbestos. Results correlated well with those obtained by using AOAC official final action method 7.061-7.065 (correlation coefficient, 0.9994). For 8 samples, the coefficients of variation ranged from 0.74 to 4.80%. Compared with the AOAC method the proposed method showed a slight negative bias of 0.1%. Compared with asbestos, ceramic fiber was easier to prepare for use, filtering was faster, and samples bumped less.

  4. Preventing oil adhesion to pipe walls in heavy crude transportation

    Energy Technology Data Exchange (ETDEWEB)

    Rivero, M.; Guevara, E.; Joseph, D. [and others

    1995-12-31

    During the transportation of heavy, extra heavy, and bitumen with water in carbon steel pipelines, the crude sticks to the internal pipe wall, reducing the flow area and as a consequence increasing the pressure drop in time. The situation may become worse if an unplanned shut down occurs, due to the phase separation by gravity. The problem. is resolved using a cement lined pipeline, with a cement composition that creates a permanent oleophobic and hydrophilic surface. These surfaces repel oil when they are hydrated in water, avoiding the occurrence of fouling at stationary and restart conditions.

    We construct a thermodynamic model for theoretical calculation of the boiling process of multicomponent mixtures of hydrocarbons (e.g., crude oil). The model governs kinetics of the mixture composition in the course of the distillation process along with the boiling temperature increase. The model heavily relies on the theory of dilute solutions of gases in liquids. Importantly, our results are applicable for modelling the process under elevated pressure (while the empiric models for oil cracking are not scalable to the case of extreme pressure), such as in an oil field heated by lava intrusions.

    This study evaluated selected bacteriologic and nutritional components of a commercially prepared ground raw horsemeat diet as part of a raw meat safety program. Six lots of meat were analyzed in triplicate. Frozen meat samples were thawed for 44 hr at 5°C. Meat samples were tested at three times during thawing (t = 0, 24, 44 hr) for selected bacteria. Samples were screened for Salmonella sp. using an enzyme-linked immunosorbent assay. Escherichia coli and total coliform bacteria were quantified using a ready-made culture medium system. Proximate, energy, macro and trace mineral composition was determined at a reference laboratory. Salmonella sp. antigen was detected in one sample of meat at t = 0 hr. Frozen meat samples had low average maximum expected numbers of E. coli and coliforms. The average maximum number of E. coli did not change significantly at t = 24 or 44 hr, but the average maximum number of coliforms increased significantly by t = 44 hr. These bacteriologic tests were easily incorporated into a raw meat safety program. Median concentrations of moisture, dry matter, crude protein, crude fat, ash, calcium, and phosphorus conformed to the guaranteed analysis but median crude fiber exceeded the guaranteed maximum. Median magnesium, potassium, and sodium concentrations conformed to the approximate nutrient content. Median concentrations of copper exceeded, whereas iron, zinc, and manganese fell below, the approximate nutrient content. Median copper and manganese concentrations exceeded the National Research Council's recommendation for adult domestic cats, whereas iron and zinc were below the National Research Council's recommendations for adult cats. © 2011 Wiley Periodicals, Inc.

    Full Text Available Actinidia arguta (Siebold et Zucc. Planch. ex. Miq. is one of the most recently domesticated fruit species with increasing commercial production worldwide. It is a well-known traditional Chinese medicine and is used to reduce blood glucose and treat atopic dermatitis. In addition, it possesses antioxidant, anticancer, and antiallergic properties. In this study, we investigated the physical antifatigue and exercise performance effects of A. arguta crude alkaloids (AACA extracted with 70% ethanol. Four groups of male Kunming mice (n = 16 were orally administered AACA at doses of 0 mg/kg/d (vehicle, 50 mg/kg/d (AACA-50, 100 mg/kg/d (AACA-100, or 200 mg/kg/d (AACA-200 for 28 days. The effect of AACA treatment on exercise performance was studied using the forelimb grip strength experiment and by the measurement of the weight-loaded swimming time. The antifatigue effect is evaluated based on fatigue-associated biochemical parameters, hepatic and muscular glycogen levels, and changes in the morphology of transverse and longitudinal sections of skeletal muscle. The results showed that AACA could elevate the endurance and grip strength in mice. The exhaustive swimming time of the AACA-50, AACA-100, and AACA-200 groups was significantly (p < 0.05 increased compared with the vehicle. The swimming time of the AACA-100 group was the longest among all groups studied. Mice in the AACA-treated groups had decreased levels of lactate, ammonia, and creatine kinase after a physical challenge compared with the vehicle group. The tissue glycogen, an important energy source during exercise, significantly increased with AACA. The morphology of transverse and longitudinal sections of skeletal muscle did not change in the vehicle group. Overall, these findings suggest that AACA possesses antifatigue effects and increases exercise performance in mice. Therefore, A. arguta may be developed as an antifatigue dietary supplement in the category of functional foods.

    Full Text Available Molecular analyses are providing new elements to decipher the origin, domestication and dispersal of native Amazonian crops in an expanding archaeological context. Solid molecular data are available for manioc (Manihot esculenta, cacao (Theobroma cacao, pineapple (Ananas comosus, peach palm (Bactris gasipaes and guaraná (Paullinia cupana, while hot peppers (Capsicum spp., inga (Inga edulis, Brazil nut (Bertholletia excelsa and cupuassu (Theobroma grandiflorum are being studied. Emergent patterns include the relationships among domestication, antiquity (terminal Pleistocene to early Holocene, origin in the periphery, ample pre-Columbian dispersal and clear phylogeographic population structure for manioc, pineapple, peach palm and, perhaps, Capsicum peppers. Cacao represents the special case of an Amazonian species possibly brought into domestication in Mesoamerica, but close scrutiny of molecular data suggests that it may also have some incipiently domesticated populations in Amazonia. Another pattern includes the relationships among species with incipiently domesticated populations or very recently domesticated populations, rapid pre- or post-conquest dispersal and lack of phylogeographic population structure, e.g., Brazil nut, cupuassu and guaraná. These patterns contrast the peripheral origin of most species with domesticated populations with the subsequent concentration of their genetic resources in the center of the basin, along the major white water rivers where high pre-conquest population densities developed. Additional molecular genetic analyses on these and other species will allow better examination of these processes and will enable us to relate them to other historical ecological patterns in Amazonia.

    Violence in the family constitutes a serious social and psychological problem with harmful consequences leading, among others, to changes in the psychological functioning of the victim and, secondarily, also the perpetrator. The aim of this study was to examine resilience in women experiencing domestic violence. The "Ego Resiliency Scale" (ERS) was used to study the group of women suffering domestic violence. The study group included 52 women aged 30-65 years (mean age: 40.15) using assistance of the Crisis Intervention Centre due to experienced domestic violence. They most often reported suffering psychological and physical violence, with the husband or intimate partner being the most common perpetrator. Study women experiencing domestic violence obtained significantly lower scores on the ERS. The lowest scores on the ERS were achieved by women suffering paternal violence, while the highest - by women experiencing violence on the part of the intimate partner. Resilience of study women suffering domestic violence was lower than resilience of the general population, i.e. individuals not experiencing domestic violence. Suffered violence inflicted by the father exerted the greatest adverse impact on resilience. It seems advisable to consider resilience in the process of providing women experiencing domestic violence with psychosocial help.

    Hydraulic fracturing operations are generating considerable discussion about their potential to contaminate aquifers tapped by domestic groundwater wells. Groundwater wells located closer to hydraulically fractured wells are more likely to be exposed to contaminants derived from on-site spills and well-bore failures, should they occur. Nevertheless, the proximity of hydraulic fracturing operations to domestic groundwater wells is unknown. Here, we analyze the distance between domestic groundwater wells (public and self-supply) constructed between 2000 and 2014 and hydraulically fractured wells stimulated in 2014 in 14 states. We show that 37% of all recorded hydraulically fractured wells stimulated during 2014 exist within 2 km of at least one recently constructed (2000-2014) domestic groundwater well. Furthermore, we identify 11 counties where most ([Formula: see text]50%) recorded domestic groundwater wells exist within 2 km of one or more hydraulically fractured wells stimulated during 2014. Our findings suggest that understanding how frequently hydraulic fracturing operations impact groundwater quality is of widespread importance to drinking water safety in many areas where hydraulic fracturing is common. We also identify 236 counties where most recorded domestic groundwater wells exist within 2 km of one or more recorded oil and gas wells producing during 2014. Our analysis identifies hotspots where both conventional and unconventional oil and gas wells frequently exist near recorded domestic groundwater wells that may be targeted for further water-quality monitoring.

    Full Text Available Floating wetlands on a container (25 L using Vetiveria zizanioides (L Nash was applied to remediate crude oil spill in water for four weeks. Three plants (height 10 cm were inserted in a pot containing rockwool, floated on crude oil spiked water. Treatment included 3 and 6 pot plants with 1% crude oil concentration. Six pot plants during 4 weeks of experiment could reduce the oil content of 91.39%, 84.60% COD, and 84.25% BOD. Meanwhile, 3 pot plants could decrease the oil content of 90.28%, 81.69% COD, and 81.10% BOD. DO at week 4 decreased. The BOD and COD did not show any significant reduction. Plants grew better in crude oil contaminated water. Those were indicated by 47.22% parent and 100% shoots could live until the study end in 1% crude oil spiked water. Meanwhile, in crude oil uncontaminated water, 30.56% parent and 40% shoots were able to live until the study end. Wet plant biomass (5.1070 g in the crude oil contaminated water was greater than the plant biomass (4.8362 g in crude oil uncontaminated water. RGR of V. zizanioides in crude oil contaminated water was 5.10 g/week and 4.83 g/week in uncontaminated water. Keywords: Phytoremediation, Crude oil, Floating wetland, Vetiveria zizanioides

    As one of the most vital energy resources in the world, crude oil plays a significant role in international economic market. The fluctuation of crude oil price has attracted academic and commercial attention. There exist many methods in forecasting the trend of crude oil price. However, traditional models failed in predicting accurately. Based on this, a hybrid method will be proposed in this paper, which combines variational mode decomposition (VMD), independent component analysis (ICA) and autoregressive integrated moving average (ARIMA), called VMD-ICA-ARIMA. The purpose of this study is to analyze the influence factors of crude oil price and predict the future crude oil price. Major steps can be concluded as follows: Firstly, applying the VMD model on the original signal (crude oil price), the modes function can be decomposed adaptively. Secondly, independent components are separated by the ICA, and how the independent components affect the crude oil price is analyzed. Finally, forecasting the price of crude oil price by the ARIMA model, the forecasting trend demonstrates that crude oil price declines periodically. Comparing with benchmark ARIMA and EEMD-ICA-ARIMA, VMD-ICA-ARIMA can forecast the crude oil price more accurately.

    Understanding the genetic structure of domestic species provides a window into the process of domestication and motivates the design of studies aimed at making links between genotype and phenotype. Rabbits exhibit exceptional phenotypic diversity, are of great commercial value, and serve as important animal models in biomedical research. Here, we provide the first comprehensive survey of nucleotide polymorphism and linkage disequilibrium (LD) within and among rabbit breeds. We resequenced 16 genomic regions in population samples of both wild and domestic rabbits and additional 35 fragments in 150 rabbits representing six commonly used breeds. Patterns of genetic variation suggest a single origin of domestication in wild populations from France, supporting historical records that place rabbit domestication in French monasteries. Levels of nucleotide diversity both within and among breeds were ∼0.2%, but only 60% of the diversity present in wild populations from France was captured by domestic rabbits. Despite the recent origin of most breeds, levels of population differentiation were high (FST = 17.9%), but the majority of polymorphisms were shared and thus transferable among breeds. Coalescent simulations suggest that domestication began with a small founding population of less than 1,200 individuals. Taking into account the complex demographic history of domestication with two successive bottlenecks, two loci showed deviations that were consistent with artificial selection, including GPC4, which is known to be associated with growth rates in humans. Levels of diversity were not significantly different between autosomal and X-linked loci, providing no evidence for differential contributions of males and females to the domesticated gene pool. The structure of LD differed substantially within and among breeds. Within breeds, LD extends over large genomic distances. Markers separated by 400 kb typically showed r2 higher than 0.2, and some LD extended up to 3,200 kb

    This paper describes pricing factors of crude oil for Asia and future problems. Price of the Middle East crude oil for Asia is determined by linking the spot price of Dubayy crude oil using as a marker. Factors affecting the pricing of marker crude oil include the information dispatching functions for prices of spot market and paper market of marker crude oil, the presence of competitive crude oil, and the correlation between market of oil products and price of crude oil. The paper market of Dubayy crude oil with a small scale of trading provides poor impact and transparency. In Asia, there is no strong competitive crude oil except the Middle East crude oil. There is only a weak price linking between crude oil and products. These are the background that the price of Middle East crude oil stays at the high level and the price adjusting functions are hard to work. The marker crude oil should be changed to another except Dubayy crude oil, and information should be dispatched from purchasers based on the stable standard crude oil. The real paper market should be created, and the force of speaking to oil producing countries should be enhanced by concentrating forces of major oil consuming countries in Asia. It is necessary to find out competitive crude oils. 5 figs., 6 tabs.

    Endogenous retroviruses (ERVs) are genomic elements that are present in a wide range of vertebrates. Although the study of ERVs has been carried out mainly in humans and model organisms, recently, domestic animals have become important, and some species have begun to be analyzed to gain further insight into ERVs. Due to the availability of complete genomes and the development of new computer tools, ERVs can now be analyzed from a genome-wide viewpoint. In addition, more experimental work is being carried out to analyze the distribution, expression and interplay of ERVs within a host genome. Cats, cattle, chicken, dogs, horses, pigs and sheep have been scrutinized in this manner, all of which are interesting species in health and economic terms. Furthermore, several studies have noted differences in the number of endogenous retroviruses and in the variability of these elements among different breeds, as well as their expression in different tissues and the effects of their locations, which, in some cases, are near genes. These findings suggest a complex, intriguing relationship between ERVs and host genomes. In this review, we summarize the most important in silico and experimental findings, discuss their implications and attempt to predict future directions for the study of these genomic elements.

    Full Text Available Domestic violence is a problem to which more attention is paid today. However, in its theoretical consideration, as well as in practical reaction, one must not lose sight of characteristics of domestic violence of one, rather numerous category of perpetrators who have psychopathic structure of personality. Domestic violence which offenders are psychopaths must be treated very carefully, because each mistake in intervention can cause much bigger damage to the victim than absence of reaction at all. Due to that, before any intervention, it would be necessary to make a diagnosis on whether the perpetrator has psychopathic structure of personality or not.

  2. How fast was wild wheat domesticated?

    2006-03-31

    Prehistoric cultivation of wild wheat in the Fertile Crescent led to the selection of mutants with indehiscent (nonshattering) ears, which evolved into modern domestic wheat. Previous estimates suggested that this transformation was rapid, but our analyses of archaeological plant remains demonstrate that indehiscent domesticates were slow to appear, emerging approximately 9500 years before the present, and that dehiscent (shattering) forms were still common in cultivated fields approximately 7500 years before the present. Slow domestication implies that after cultivation began, wild cereals may have remained unchanged for a long period, supporting claims that agriculture originated in the Near East approximately 10,500 years before the present.

    2018-02-01

    Full Text Available Crude oil transport is an essential task in oil and gas industries, where centrifugal pumps are extensively used. The design of a centrifugal pump involves a number of independent parameters which affect the pump performance. Altering some of the parameters within a realistic range improves pump performance and saves a significant amount of energy. The present research investigated the pump characteristics by modifying the number of blades and the exit blade-angles. Reynolds-Averaged Navier-Stokes equations with standard k-ε two-equation turbulence closure were used for steady and incompressible flow of crude oil through the pump. The experimental set-up was installed and the pump performance calculated numerically  was compared with the experiments.   The investigations showed that the number of blades and the exit blade-angles have a significant influence on the head, shaft power, and efficiency. The vortical flow structures, recirculation and reverse flow characteristics around the impeller were investigated to explain the flow dynamics of impeller and casing. A larger number of blades on the rotor showed dominant streamlined flow without any wake phenomena. The combined effect of the number of blades and exit blade angle has led to an increase in head and efficiency through the parametric optimization.

    Nyamplung (Calophylluminophyllum) has many benefits ranging from roots, stems, leaves, until seeds. In this seed, C. inophyllum contained significantly high amount of crude oil (70.4%). C. inophyllum oil is known as non edible. Therefore Indonesian people generally only know that seeds can produce oil that can be used for biodiesel. In this work, the fragmentation of fatty acid in triacylglycerols (TAG) was studied. The isolation process was started with separation of non polar lipid fraction (NPLF) from crude C. inophyllum oil via batchwise multistage liquid extraction. TAG was obtained in high purity (99%) and was analyzed by Thin Layer Chromatography (TLC) and Gas Chromatography - Mass Spectrometry (GCMS). It was found that fatty acids of TAG are palmitic acid (C16:0), stearic acid (C18:0), oleic acid (C18:1c), linoleic acid (C18:2c), and linolenic acid (C18:3c). Moreover, TAG isolated from C. inophyllum oil was promising as edible oil.

    Science.gov (United States)

    Determining the long-term effects of crude oil exposure is critical for ascertaining population-level ecological risks of spill events. A 19-week complete life-cycle experiment was conducted with the estuarine sheepshead minnow (Cyprinodon variegatus) exposed to reference (uncontaminated) sediment spiked with laboratory weathered South Louisiana crude (SLC) oil at five concentrations as well as one unspiked sediment control and one seawater (no sediment) control. Newly hatched larvae were exposed to the oiled sediments at measured concentrations of fish were assessed for growth, survival, and reproduction. Resulting F1 embryos were then collected, incubated, and hatched in clean water to determine if parental full life-cycle exposure to oiled sediment produced trans-generational effects. Larvae experienced significantly reduced standard length (5–13% reduction) and wet weight (13–35% reduction) at concentrations at and above 50 and 103 mg tPAH/kg sediment, respectively. At 92 and 132 days post hatch (dph), standard length was reduced (7–13% reduction) at 199 and 109 mg tPAH/kg dry sediment, respectively, and wet weight for both time periods was reduced

    This study investigates the joint phenomena of permanent and transitory components in conditional variance and jump intensity along with verification of structural breaks for crude oil prices. We adopt a Component-ARJI model with structural break analysis, utilizing daily data on West Texas Intermediate crude oil spot and futures contracts. The analytical results verify the existence of permanent and transitory components in conditional variance, with the permanent component of conditional variance increasing with the occurrence of a sudden major event (such as the Iraqi Invasion of Kuwait, Operation Desert Storm and the war between the US and Iraq), and a relatively greater increase in the transitory component over the same period. Notably, jump intensity fluctuates with an increase in the transitory component of conditional variance in response to abnormal events. It is the transitory component which serves as the primary influential factor for jumps in returns; therefore, speculators are willing to take large risks, particularly with respect to anticipating future price movements, or gambling, in the hopes of rapidly making substantial gains; thus, speculators prefer the temporary volatility component and engage in trade activities. However, investors prefer the permanent volatility component, because they may well be better off relocating their assets into more stable portfolios to outperform the market portfolio over the long run.

    This study was conducted to determine the susceptibility of plastic (i.e., PEX, HDPE and CPVC) and copper pipes to short-term contamination by crude oil. Pipes were exposed to highly and slightly contaminated drinking water for the typical duration of Do Not Use drinking water orders. PEX pipes sorbed and desorbed the greatest amount of monoaromatic hydrocarbons (MAHs), whereas copper pipes were less susceptible to contamination. For benzene, toluene, ethylbenzene, and xylenes (BTEX) quantified in water, only benzene exceeded its health based maximum contaminant level (MCL). The MCL was exceeded for copper pipe on day 3, for CPVC pipe through day 9, and PEX and HDPE pipes through day 15. The BTEX compound concentration in water after the pipes were returned to service depended on the initial crude oil concentration, material type, and exposure duration. Total organic carbon (TOC) measurement was not helpful in detecting oil contaminated water. Except BTEX, trimethylbenzene isomers and a couple of polycyclic aromatic hydrocarbons (PAHs) with and without MCLs were also detected desorbing from PEX-A pipe. Oil contaminated water must be thoroughly characterized and pipe type will influence the ability of drinking water levels to return to safe limits. Copyright © 2017 Elsevier B.V.

    2013-12-01

    Chronic administration of aged garlic extract has been shown to prevent memory impairment in mice. Acute and chronic (21 days) effects of marketed formulation of crude garlic extract (Lasuna) were evaluated on learning and memory in mice using step down latency (SDL) by passive avoidance response and transfer latency (TL) using elevated plus maze. Scopolamine (0.4 mg/kg, ip) was used to induce amnesia in mice and piracetam (200 mg/kg, ip) served as positive control. In the acute study, Lasuna (65 mg/kg, po) partially reversed the scopolamine-induced amnesia but failed to improve learning and memory in untreated animals. Chronic administration of Lasuna (40 mg/kg/day for 21 days) significantly improved learning both in control and scopolamine induced amnesic animals. Influence of Lasuna on central cholinergic activity and its antioxidant properties were also studied by estimating the cortical acetylcholinesterase (AchE) activity and reduced glutathione (GSH) levels respectively. Chronic administration of Lasuna inhibited AchE, while increasing GSH levels. Thus the results indicate that long-term administration of crude garlic extract may improve learning and memory in mice while the underlying mechanism of action may be attributed to the anti-AchE activity and anti-oxidant property of garlic.

    Studies that deal with child maltreatment have become relevant during these past years. One important aspect to consider is the impact of maltreatment on the cognitive functioning and more precisely on language. Our objective is to analyze the different components in the comprehension and production of language in children victims of domestic abuse in Childreńs Homes. The sample consists of 104 participants divided in two groups. A group of children who have just been institutionalized due to domestic abuse (VG) (Age: 8 years 2 months with a standard deviation of 1, 5 years) without previous treatment; a group of comparison (CG) made up by children who have not been victim of domestic violence (Age: 8 years 6 months with a standard deviation of 2 years and a month), with similar characteristics of gender, age and schooling. The Child Neuropsychological Assessment by Matute, Rosselli, Ardila and Ostrosky (2007) was applied. This test includes metalinguistic, oral and written comprehension and expression skills. The VG group showed low scores in all components of the analyzed language with exception to the discourse, syllable and non-word dictation compared to the CG children. The alterations of the language observed in these children semantic suggest a lack of consolidation of phonological coding and a low use of code. From our findings an early language evaluation in these children can be of especial interest to apply timely intervention programs with the aim of diminishing the impact caused by domestic violence on school failure which is a frequent trait in these children.

    Fifteen crude oil degrading bacteria were isolated from oil contaminated sites in the Persian Gulf at Khorramshahr provenance. These bacteria were screened with two important factors such as growth rate on crude oil and hydrocarbon biodegradation, and then three strains were selected from 15 isolated strains for further study. One strain (PG-Z) that show the best crude oil biodegradation was selected between all isolates. Nucleotides sequencing of the gene encoding for 16S rRNA show that strain PG-Z belong to Corynebacterium variabile genus. This strain was efficient in degrading of crude oil. This strain was capable to degraded 82% of crude-oil after one week incubation in ONR7a medium. The PG-Z strain had high emulsification activity and biosurfactant production between all isolates. GC-MS analysis shows that C. variabile strain PG-Z can degrade different alkanes in crude oil. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Lactobacillus delbrueckii cultured with peanut oil cake as the carbon source yielded 5.35 mg ml(-1) of biosurfactant production. Five sets of microcosm biodegradation experiments were carried out with crude oil as follows: set 1 - bacterial cells+crude oil, set 2 - bacterial cells+crude oil+fertilizer, set 3 - bacterial cells+crude oil+biosurfactant, set 4 - bacterial cells+crude oil+biosurfactant+fertilizer, set 5 - with no bacterial cells, fertilizer and biosurfactant (control). Maximum degradation of crude oil was observed in set 4 (75%). Interestingly, when biosurfactant and bacterial cells were used (set 3), significant oil biodegradation activity occurred and the difference between this treatment and that in set 4 was 7% higher degradation level in microcosm experiments. It is evident from the results that biosurfactants alone is capable of promoting biodegradation to a large extent without added fertilizers. Copyright © 2010 Elsevier Ltd. All rights reserved.

    We evaluate the potential for electric power saving in Mexico that would follow the substitution of old, low efficiency domestic refrigerators with modern, high efficiency ones. Our results indicate that a total substitution of domestic refrigerators would save 4.7 TWh/year, which represents 33% of the annual total consumption of 14.1 TWh. Assuming an average daily use of 14 h for domestic refrigeration, 900 MW of electricity would be saved. An annual substitution of 20% over 5 years would save approximately 1 TWh a year and almost 180 MW would be released. It is recommended that this program of replacement should be supported by the Federal and State governments, beginning with the States (which have more direct influence), and with the oldest, least efficient refrigerators along the lines followed in programs that introduced fluorescent compact lamps.
