The importance of particle shape in terms of its effects on the behaviour of powders and other particulate systems has long been recognised, but particle shape information has been rather difficult to obtain and use until fairly recently, unlike its better-known counterpart, particle size. However, advances in computing power and 3D image acquisition and analysis techniques have resulted in major progress being made in the measurement, description and application of particle shape information in recent years. Because we are now in a digital era, it is fitting that many of these advanced techniques are based on digital technology. This review article aims to trace the development of these new techniques, highlight their contributions to both academic and practical applications, and present a perspective for future developments.

Hepatocellular carcinoma(HCC) is an aggressive tumor that often occurs in the setting of chronic liver *** patients do not initially manifest any symptoms of HCC and present late when cure with surgical resection or transplantation is no longer *** this reason,patients at high risk for developing HCC are subjected to frequent screening *** surgical management of HCC is complex and requires an inter-disciplinary *** resection is the treatment of choice for HCC in patients without cirrhosis and is indicated in some patients with early cirrhosis(Child-Pugh A).Liver transplantation has emerged in the past decade as the standard of care for patients with cirrhosis and HCC meeting Milan criteria and in select patients with HCC beyond Milan ***-regional therapy with transarterial chemoembolization,transarterial embolization,radiofrequency ablation and other similar local treatments can be used as neo-adjuvant therapy to downstage HCC to within Milan criteria or as a bridge to transplantation in patients on transplant wait list.

In the past, international Evidence law reformers have focused primarily on substantive evidentiary doctrines. However, for reforms to be effective, the courts and legislatures must state the revised doctrines in a form that promotes the overall objectives of the legal system. The basic choice facing reformers is among a creed identifying broad goals, a code stating flexible principles, and a catalogue prescribing detailed rules. In the past, especially in the United States, there was a consensus among Evidence scholars that the code format is preferable. However, if a key objective of a national legal system is to encourage pretrial disposition of cases, the courts and legislatures should give serious thought to utilizing a catalogue format. That format is especially attractive in the doctrinal areas such as privilege in which evidentiary rules are intended to affect primary behavior outside the courtroom.

Hunter-gatherer communities in the American Southeast reached an apogee of social and political complexity in the period between ca. 4200 and 3000 cal yr BP. In the lower Mississippi Valley(LMV) the Poverty Point culture defined this period of socio-political elaboration. However, following a significant period of climate change that led to exceptional flooding and a major reorganization of the course of the Mississippi River, this culture collapsed beginning ca. 3300–3200 cal yr BP and the LMV was abandoned for the subsequent 500 years. In this study, we use data from the jaketown site in the Yazoo Basin of west-central Mississippi to refine the chronology of the climate event that caused the collapse of the Poverty Point culture. A large flood buried Poverty Point-era occupation deposits at jaketown around 3310 cal yr BP. Lateral migration of the Mississippi River during flooding led to inundation of the Yazoo Basin and re-occupation of ancient river courses. A coarse sand stratum topped by a more than a meter-thick fining upward sediment package marks a crevasse deposit caused by a rupture of the natural levee at jaketown. This levee breach was part of a larger pattern of erratic flooding throughout the LMV and is associated with major landscape evolution and the abandonment of Poverty Point sites within the valley. Early Woodland peoples re-colonized the crevasse surface after ca. 2780 cal yr BP. Following this event, the jaketown site and the eastern Yazoo Basin witnessed a period of landscape stability that lasts to this day. These archaeological data demonstrate how climate change and natural disasters can lead to socio-political dissolution and reorganization even in relatively small-scale hunter-gatherer populations.

Environmental change attracts particular attention by biologists concerned with the performance of biological systems under stress. To investigate these, dose–response relationships should be clarified. It was previously assumed that the fundamental nature of biological dose–responses follows a linear model, either with no threshold or with a threshold below which no effects are expected to occur in biological endpoints. However, substantial literature, including widespread documentation in plants, has revealed that hormesis commonly occurs. Hormesis is highly generalized and can be utilized as a quantitative measure of biological plasticity. Conditioning induced by adaptive responses also occurs in the framework of hormesis and is of particular importance to environmental change biology with regards to evolutionary *** paper presents additional evidence for hormetic dose responses induced by temperature in plants. The current understanding on hormesis provides a perspective for next generation environmental change research. Hormesis should have a central role in environmental change biology of vegetation.

Unused medications have the possibility of being abused, causing serious harm to individuals who were not prescribed the drug. The Food and Drug Administration(FDA) recommends the proper disposal of unused prescribed medications to maintain safety and prevent environmental hazards. However, many of the current disposal techniques do not properly address safety. A drug disposal pouch containing granular activated carbon offers a unique disposal method to deactivate residual or expired medication in a convenient, effective, and safe manner. A robust and validated method for methylphenidate hydrochloride and loxapine succinate was developed using high-performance liquid chromatography(HPLC) and the deactivation efficiency of the disposal system was tested. Methylphenidate hydrochloride was analyzed on a C18 analytical column(250 mm ?4.60 mm, 100?) using acetonitrile-water(0.05%(v/v) trifluoroacetic acid) as the mobile phase at a flow rate of1.0 mL/min with a run time of 15 min and retention time of 7.8 min. Loxapine succinate was separated on a C8100?(250 mm ? 4.6 mm, 5 mm) column maintained at 25 °C using a flow rate of 1.0 mL/min. The run time was 10 min and the retention time of the drug was around 4.6 min. Mobile phase was composed of acetonitrile and water(0.3% triethylamine) at pH 3.0 as 40:60(v/v). Reference standard solutions(100 mg/mL) for both drugs were prepared by dissolving in mobile phases. These methods provide good linearity(R2? 0.999) over the range of 5–100 mg/mL for methylphenidate hydrochloride and 0.1–100 mg/mL for loxapine succinate. The assay methods were successfully applied to study the deactivation of these drugs.
