It was found that diversified artificial and natural buffer/detention landscape structures distributing along the ephemeral stream channel in this watershed played an important role of pollutants removal on downstream water quality, especially they have control effect on the diffuse P-pollutants transport process. Surface flow velocity was reduced sharply after passing through these structures. During continuous runoff events, the removal rate of TSS, TP, TDP, DRP by the whole system were 66.7%, 60.7%, 48.4%, and 43.3%, respectively. During discontinuous runoff events, removal rate of pollutants by the whole system was higher due to there was no or little surface water and pollutants exported from the watershed, of which removal rate of pollutants all exceeded 99%. The statistical analysis results of runoff events(n=8) indicated that dry pond was the steadiest structure for controlling diffuse P-pollutants export.展开更多

In Australia, singular temporal patterns for design storms have governed the inputs of hydrograph generation and in turn the design process of OSD for the last three decades. This paper raises the concern that many existing OSD systems designed using the singular temporal pattern for design storms may not be achieving their stated objectives when they are assessed against a variety of alternative temporal patterns. The performance of twenty real OSD systems was investigated using two methods:(1) ensembles of design temporal patterns prescribed in the latest version of Australian Rainfall and Runoff, and (2) real recorded rainfall data taken from pluviograph stations modeled with continuous simulation. It is shown conclusively that the use of singular temporal patterns is ineffective in providing assurance that an OSD will mitigate the increase to peak discharge for all possible storm events. Ensemble analysis is shown to provide improved results. However, it also falls short of providing any guarantee in the face of naturally occurring rainfall.展开更多

A key pollutant that DBs serve to settle out is particulate phosphorus, which adsorbs onto sediment. This study examines the sediment phosphorus concentration and its relationship with the particle size of sediment microcosms from pre- and post-rain event samples obtained from six DBs located in Clark County, Nevada. DBs were allotted a land use classification to determine if there was a correlation between the sediment phosphorus concentration and surrounding land use. The curve number method was used to calculate the runoff and subsequent phosphorus carried into the DB by the runoff. Our data show sediment phosphorus concentrations to he highest in soils from undeveloped areas. Runoff amount also plays a substantial role in determining the amount of phosphorus brought into the DB by sediment. This research has implications for improvement of water quality in arid regions.展开更多

Increasing aberrant behaviors in children have been linked to mental disorders. Assessment of presence mental health disorders as the main cause of these behaviors would be important to restore mental health of children and assist the system to impose a fair trial. Objective: This study aimed to determine the presence of mental disorders and associated factors among children and adolescents within Dar es Salaam juvenile systems and explore factors that may affect their mental health while in juvenile home. Methods: The mixed research method was used to estimate prevalence of mental disorders by a cross-sectional study and a qualitative method was applied to evaluate mental disorders according to DSM IV TR criteria. Results: The overall prevalence of mental dysfunction by mental status evaluation was 3%: 95% (CI;25.3 - 43.2;n =37 out of 108). The younger age group (13 - 15) years presented with a prevalence of 30%: 95% (CI;14.7 - 44.5) while the older adolescents (16 - 17 years) had a prevalence of 55%: 95% (CI;43.3 - 67.1). Attention deficit disorder was found in some children, some had history of drug and alcohol abuse, with few sexual disorders, depression and brief psychotic reaction and was found to be common among adolescent with unstable family situations such as death of parents, divorce of parents, and single parented children. Conclusion: Findings are suggestive that there is a presence of underlying mental disorders in some of the adolescents in the juvenile detention. Thus mental health screening for children in juvenile homes should be made mandatory in order to identify causes of aberrant behavior as well as provide treatment, prevent complications and maintain mental health of these children. Mental health screening for such children would also assist in conducting a fair trial for these emancipated children.展开更多

It marks a further improvement of China’s mechanism to aid urban vagrants and beggars. The new regulation has been enacted to replace the two-decade-old Measures for the Internment and Deportation of Urban Vagrants and Beggars.

Furthermore, previous findings have described a practice in which forensic examiners use the DSM SCID axis II for APD to confirm an ICD 10 diagnosis of DPD. Clinical investigation supported by the use of SCID Axis II for quality assurance was performed on almost half the population of inmates (46.4%) in preventive detention at a high security prison. The inmates had all committed severe violent acts including murder. All the information obtained by applying the DSM IV-TR criteria was tested against the ICD-10 Research Criteria (ICD-10-RC) for Dissocial Personality Disorder (ICD-10, DPD). It was found that all inmates met the ICD-10-RC for (DPD) and the DSM-IV-TR definition for Adult Antisocial Behavior (AAB). On the other hand, none met the DSM-IV-TR criteria for (APD). The SCID Axis II failed to identify inmates with APD because the DSM-IV-TR C-criteria, referring to symptoms of childhood Conduct Disorder (CD), were not met. These findings raise important questions since the choice of diagnostic system may influence whether a person’s clinically described antisocial behaviour should be classified as a personality disorder or not. For the inmates, a diagnosis of APD or DPD may compromise their legal rights and affect decisions on prolongation of the preventive detention. Studies have shown that combining the DSM and the ICD diagnostic systems may have consequences for the reliability of the diagnosis.展开更多

As a legal facility for carrying out criminal detention, a pre-trial detention house should remain neutral and safeguard detainees’ substantive and procedural rights. It should be an important base for the country to respect and protect human rights. At the macro level, protecting detainees’ rights comprises two aspects: 1) procedural rights, regarding which the principle of presumption of innocence should be applied; and 2) detainee treatment, regarding which the principle of socialization should be applied. At the current stage of China’s rights protection situation, China should improve detainees’ rights, such as the right to have an individual bed, the rights to health care and religious freedom, rules regarding the use of legirons, and transparency and independent monitoring mechanisms.展开更多

There is, therefore, still little understanding of the main mechanisms driving the substantial transport of MP across different environmental compartments. Storm events can transport MP beyond boundaries, such as from the land to groundwater or the ocean, as has already been discovered for organic carbon transport. Urban stormwater detention ponds are suitable environments to study the impact of stormwater on the environmental fate and transport of MP. Herein, we investigate the longitudinal and vertical distribution of MP within two detention ponds with different physical characteristics. Soil samples were collected at various locations and from multiple depths (surface and subsurface layers) for measuring MP concentrations using fluorescence microscopy. Our findings show that MP are retained more near the inlet of the ponds, and MP of larger sizes were found more abundantly near inlets than outlets. We also found that MP mass and sizes decrease from surface soil to subsurface soil. In the pond, where vegetation (grass root network) was more considerable, MP were found more evenly distributed along the depth. In terms of shape, the fragments were the most abundant MP shape.展开更多

The objective was to study the epidemiological and psychosocial profile of delinquent children and adolescents under court order (DCAUCO) in Benin civil prisons in 2015. Methods of study: It was a descriptive and cross-sectional study which involved 117 children aged 11 to 18 years, recruited from 6<sup>th</sup> May to 10<sup>th</sup> September 2015 in nine Civil Prisons and a Child and Adolescent Care Center in Benin. Data were collected through face-to-face interview between the interviewer and the interviewee in addition to ASSIST-WHO, Family Assessment Device and ParentalAcceptance and Rejection Scale. Results: The average age was 16.1 ± 1.1 years, ranging from 11 to 18 years. Sex ratio M/F was 22.4. School dropout rate was 76.9%. Orphans represented 53.9%. The proportion of juvenile offenders coming from broken families was 30.8%. Theft (46.2%) and rape (19.7%) were the main offenses committed. 99.1% had no criminal records and the judge requested for all of them a detention warrant. Psychoactive substance consumption records (46.2%) were found, including: alcohol (46.2%), tobacco (23.9%), and cannabis (10.3%). They felt maternal and paternal absence respectively in 48.7% and 44.4% cases and pleaded guilty in 71.8%. Pleading guilty was a resilience factor on which the counseling would have to rely for their rehabilitation and social reintegration.展开更多

Sufficient experimental methods are adopted to compare the computer simulations, the validity of which is verified by the experiment results from a wave tank laboratory. In the experiment, the motion curves of heaving buoy are with small fluctuations, mainly caused by the PMTLG's detent force. For the reduction of these small fluctuations and a maximum operational efficiency of the direct-drive wave energy conversion system, the PMTLG's detent force minimization technique and the heaving buoy optimization will be discussed. It is discovered that the operational efficiency of the direct-drive wave energy conversion system increases dramatically after optimization. The experiment and optimization results will provide useful reference for the future research on ocean wave energy conversion system.展开更多

The detent force, which is divided into two components, i.e. resulting from the end effect and resulting from the slotting effect, can be analyzed respectively by the finite element method (FEM). To reduce the detent force arising from the end effect, several optimal design techniques are utilized, namely, adopting the suitable length and end shape of the primary armature. The detent force resulting from the slotting effect is reduced by means of skewing and adjusting the width of the magnets mounted on the secondary armature, and adopting the fractional slots of the primary armature. The validity of the analytical detent force predictions and the effectiveness of the detent force reduction techniques are verified by the experimental measurements.展开更多

Dealing with polluted storm- water discharge is a great challenge. Stormwater runoff from an urban catchment with a combined sewer system was sampled and analyzed over a three-year period. Results indicate that wet weather flows account for 66%, 31%, 17%, and 13 % of the total load of suspended solids (SS), chemical oxygen demand (COD), total nitrogen, and total phosphorus, respectively. The first flush of COD and SS was significant in all runoff events. More than 50% of the SS and COD loads were transported by the first 30% of runoff volume. Storage and treatment of the first 10 mm from each combined sewer overflow event could reduce more than 70% of the annual COD overflow load. An integrated solution is recommended, consisting of a tank connected to the WWTP and a detention pond, to store and treat the combined sewer overflow (CSO). These results may be helpful in mitigating CSO pollution for many other urban areas in China and other developing countries.展开更多

文摘A direct-drive wave energy conversion system based on a three-phase permanent magnet tubular linear generator (PMTLG) and a heaving buoy is proposed to convert wave energy into electrical energy. Sufficient experimental methods are adopted to compare the computer simulations, the validity of which is verified by the experiment results from a wave tank laboratory. In the experiment, the motion curves of heaving buoy are with small fluctuations, mainly caused by the PMTLG's detent force. For the reduction of these small fluctuations and a maximum operational efficiency of the direct-drive wave energy conversion system, the PMTLG's detent force minimization technique and the heaving buoy optimization will be discussed. It is discovered that the operational efficiency of the direct-drive wave energy conversion system increases dramatically after optimization. The experiment and optimization results will provide useful reference for the future research on ocean wave energy conversion system.

文摘The detent force of a permanent magnet linear synchronous motor (PMLSM) is analyzed and the corresponding optimization methods are presented to reduce it. The detent force, which is divided into two components, i.e. resulting from the end effect and resulting from the slotting effect, can be analyzed respectively by the finite element method (FEM). To reduce the detent force arising from the end effect, several optimal design techniques are utilized, namely, adopting the suitable length and end shape of the primary armature. The detent force resulting from the slotting effect is reduced by means of skewing and adjusting the width of the magnets mounted on the secondary armature, and adopting the fractional slots of the primary armature. The validity of the analytical detent force predictions and the effectiveness of the detent force reduction techniques are verified by the experimental measurements.
文摘Northeast Asia has all along been a place of great importance for major powers in the Far East. Because of its special geographical position, these powers have competed against each other for spheres of influence in the region since the very beginning of the 20th century. Therefore, the present detente on the Korean peninsula will inevitably affect some big powers’ interests and exert a far-reaching influence on Asia-Pacific and world security situation.
文摘An older urban district in Wuhan, China, is transitioning from discharging sewage and stormwater directly into lakes, to directing the sewage to wastewater treatment plants (WWTPs). Dealing with polluted storm- water discharge is a great challenge. Stormwater runoff from an urban catchment with a combined sewer system was sampled and analyzed over a three-year period. Results indicate that wet weather flows account for 66%, 31%, 17%, and 13 % of the total load of suspended solids (SS), chemical oxygen demand (COD), total nitrogen, and total phosphorus, respectively. The first flush of COD and SS was significant in all runoff events. More than 50% of the SS and COD loads were transported by the first 30% of runoff volume. Storage and treatment of the first 10 mm from each combined sewer overflow event could reduce more than 70% of the annual COD overflow load. An integrated solution is recommended, consisting of a tank connected to the WWTP and a detention pond, to store and treat the combined sewer overflow (CSO). These results may be helpful in mitigating CSO pollution for many other urban areas in China and other developing countries.
