Multiple stable isotope characterization as a forensic tool to distinguish acid scavenger samples

Acid scavengers are frequently used as stabilizer compounds in a variety of applications. When used to stabilize volatile compounds such as nerve agents, the lower volatility and higher stability of acid scavengers make them more persistent in a post-event forensic setting. Compound-specific isotope analysis of carbon, nitrogen, and hydrogen in three acid-scavenging compounds (N,N-diethylaniline, tributylamine, and triethylamine) were used as a tool for distinguishing between different samples. Combined analysis of multiple isotopes improved sample resolution, for instance differentiation between triethylamine samples improved from 80% based on carbon alone to 96% when combining with additional isotope data. The compound-specific methods developed here can be applied to instances where these compounds are not pure, such as when mixed with an agent or when found as a residue. Effective sample matching can be crucial for linking compounds at multiple event sites or linking a supply inventory to an event.     

Good Faith,Flawed Assets and the Emasculation of the UK Anti‐Deprivation Rule

The Supreme Court's unanimous decision in Belmont Park Investments Pty Ltd v BNY Corporate Trustee Services Ltd and Lehman Brothers Special Financing Inc is of major significance to lenders, especially those in the global structured finance market. This case confirms the validity of commonly used insolvency‐triggered secured‐priority flip clauses, and, more generally, suggests a dramatically reduced role for the common law anti‐deprivation principle. The decision may not fully resolve market uncertainty, however, given the particular analysis adopted in the case itself (analysed here) and its divergence from the US statutory approach to the same principle.     

故意伤害罪新论

由于我国刑法只规定一个伤害故意,因此,当行为人出于轻伤的故意导致他人重伤结果,应当怎样处罚,不仅在刑法理论中没有一个统一的基准,在司法实践中也是见仁见智。实施暴力行为,导致被害人重伤或死亡的,应当属于故意伤害罪的结果加重形态。在故意伤害的情况下,即便有被害者的承诺,由于作为伤害的社会意义并没有变更,因此,不能阻却构成要件的符合性。但是,基于被害者承诺的违法性的阻却,在某种情况下可以成立。阻却违法性的判断,应当根据被害者处分自己身体的安全这一法益,是否具有社会相当性而进行。针对同时伤害的情况,不应认定为共同伤害。     

Transformation: the Progression of Immigration Petitions for Transgender Spouses

U.S. citizens who marry foreign nationals may petition for their spouses so that the couple can reside permanently together in the United States. The guidelines set forth in the U.S. Citizenship and Immigration Services Adjudicator's Field Manual provide guidance to immigration officials for determining whether to grant or deny spousal petitions. Previously, the Adjudicator's Field Manual imposed a requirement that transgender individuals undergo costly and dangerous sex reassignment surgery in order to qualify as married for the purposes of a spousal petition. However, revisions to the Adjudicator's Field Manual issued in April 2012 provide transgender binational couples the opportunity to remain together in the United States without forcing one partner to undergo sex reassignment surgery. Given the history of discrimination against transgender individuals under U.S. immigration law, these revisions are a significant step in equality for transgender couples. Although these revisions provide many transgender binational couples with a means to remain together in the United States, this Note proposes that, to continue on the path toward equality for transgender couples, special guidelines should not be applied to marriages involving transgender partners if their marriage is deemed a valid heterosexual marriage in the state where solemnized. The goals of U.S. immigration law and compliance with the federal definition of marriage can be achieved without implementing individualized guidelines for transgender binational couples.

Key Points for the Family Court Community:
• Transgender spouses of a binational couple should not be subjected to additional guidelines when submitting spousal petitions that, if granted, would afford the couple the opportunity to reside together in the United States
• Transgender individuals should not be subjected to disparate treatment solely because the U.S. Citizenship and Immigration Services seeks to enforce discriminatory provisions of the Defense of Marriage Act
• A marriage should be recognized by immigration law if it is a valid marriage under the law of the state where the marriage was celebrated
• In order to achieve U.S. immigration law's mission of family unification, nontraditional couples should be afforded the same opportunity to remain together in the United States without additional scrutiny

     

Maternal Separations During the Reentry Years for 100 Infants Raised in a Prison Nursery

Prison nurseries prevent maternal separations related to incarceration for the small subset of children whose pregnant mothers are incarcerated in states with such programs. For a cohort of 100 children accepted by corrections into one prison nursery, subsequent separation patterns are analyzed. The largest numbers are caused by corrections' removal of infants from the nursery and infants reaching a one-year age limit. Criminal recidivism and substance abuse relapse threaten continued mothering during reentry. Focused and coordinated services are needed during prison stay and reentry years to sustain mothering for women and children accepted into prison nursery programs.     

The effect of electrical lighting power and irradiance on indoor-grown cannabis potency and yield

The floral development and potencies [Δ(9) -tetrahydrocannabinol (THC) contents] of cannabis plants were compared when grown indoors under high-pressure sodium lamps consuming electrical power at three densities (270, 400, and 600 W/m(2)). After a 3-week vegetative phase, plants were grown for 8 weeks, with lamps maintaining an artificial day length of 12 h. Foliar and floral yields were measured. Gas chromatography was used to measure the content of the psychoactive cannabinoid THC. Mean yields per unit of electrical power in each lighting regime ranged from 0.9 to 1.6 g/W, the highest being achieved in the lowest irradiance regime. The individual potencies of the separated leaf and flower materials were not affected by increasing irradiance. However, there was a corresponding increase in the overall potency of the aerial plant tissue. This was because of the plants in brighter conditions producing a higher proportion of floral material.     

Drug-facilitated sexual assault using tetrahydrozoline

Drug-facilitated sexual assault (DFSA) has been defined as the use of a chemical agent to facilitate a sexual assault. We report two cases of the use of tetrahydrozoline for DFSA. We believe this is the first report with urinary quantification of tetrahydrozoline levels postassault. Blood and urine were obtained c. 20 h postexposure in two cases of reported DFSA. Tetrahydrozoline was not detected in blood but was identified in urine in both victims. After initial identification in the urine using the 2010 update to the AAFS mass spectrometry database library, tetrahydrozoline was quantified at 114 and 150 ng/mL, respectively, using GC/MS. Two unique clinical features reported in these cases were intermittent periods of consciousness and postexposure vomiting. Use of GC/MS was successful in identifying tetrahydrozoline in the 100 ng/mL range up to 20 h postexposure. For victims with late presentation, urine may be a better sample for evaluation for tetrahydrozoline.     

Rapid in situ repeatable analysis of drugs in powder form using reflectance near-infrared spectroscopy and multivariate calibration

This study takes the first step toward in situ analysis of powder drugs which does not require any alteration of the samples. A fast, inexpensive analytical method based on reflectance near-infrared (NIR) spectrometry and multivariate calibration was applied. A diode-array fiber-optic portable spectrometer in the 900-1700 nm range was employed. Samples were laboratory-prepared ternary powders (diacetylmorphine, caffeine, and paracetamol). Partial least squares regression was applied. The choice of the standard samples for calibration and validation was performed through a D-optimal experimental design. The explained variance was higher than 90%, and the relative root mean square errors were <2%. The number of principal components (6) was very low when compared with the number of raw variables (356 absorbance values). Response plots showed slopes and intercepts were very close to optimal values. Correlation coefficients ranged between 0.909 and 0.989. The method here proposed proved to be competitive with Fourier transform NIR spectrometry.
