Curcumin, the main bioactive compound found in turmeric rhizomes, has a wide variety of applications in the clinical field that is why it attracts researchers from all over the world. While there are various studies on curcumin extraction and quantification, comparison of curcumin content according to the soil profile and cultivation period has not been performed yet in our knowledge. Curcumin to be a genuine natural product having impressive anti-oxidant and anti-inflammatory properties, treating a wide range of diseases. Curcumin is a special gift to humans given by mother-nature to help them curing many diseases. Turmeric, the plant containing a significant amount of this molecule, has been used for many centuries as a traditional medicine to cure skin problems, digestive issues, as painkiller, and much more. From the past two centuries, scientists found many applications of this molecule in the clinical field. There are still many properties of this wonder drug that need to be discovered. However, the obstacle in this track is difficulty in extracting the pure and high amounts of curcumin from turmeric rhizomes. For this reason, many researchers have searched about many techniques to extract curcumin from turmeric rhizomes, of which ultra-high-performance liquid chromatography-mass spectrometry has been found very efficient. The review will assist the researchers to discover and choose the plant to develop adequate medicine for establishing cost-effective treatments.

High Density Packaging

High density packaging of semiconductor devices is necessary for high performance in compact electronic systems. But the assembly technology must also remain cost attractive.Through the development efforts conducted during the past years in the world, the Tape Automated Bonding – TAB – has become the assembly technology allowing a very high density packaging. In combination with substrate technology it has grown into a complete, cost effective, micropackaging concept.The paper describes the main technical characteristics of this packaging concept. Specific equipments for TAB were designed and built by CII-Honeywell Bull for installation in the factory. These equipments are not only those, directly related to the TAB technology processing steps but include also other equipments like high precision thick film printer.The main features of the new micropackaging facility are also presented. Some examples of high density packages built with tape automated bonding are described and some of the main quality and reliability aspects are discussed.

Panicum Dichotomiflorum

Consumption of certain grasses belonging to the genus Panicum has been found to cause hepatogenous photosensitization and crystal-associated cholangiohepatopathy in small ruminants, and liver disease in horses, in many areas of the world. We describe herein the clinical findings, microscopic lesions, and steroidal saponin analysis of Panicum dichotomiflorum associated with fatal toxicosis in 3 juvenile goats in Nebraska. The disease presentation in our case was fulminant, with anorexia, marked icterus, and death for all affected animals in less than a week. Photosensitization was not observed. The microscopic lesions consisted of severe crystal-associated cholangiohepatopathy and nephropathy, with aggregates of clear or refractile and birefringent, acicular crystals present within bile ducts, macrophages, hepatocytes, and renal tubules. High-performance liquid chromatography–mass spectrometry of the grass samples demonstrated that dichotomin was the major steroidal saponin present (0.89 µg/mg); protodioscin was also present (0.059 µg/mg). The findings were consistent with ingestion of steroidal saponins, and P. dichotomiflorum was identified as the predominant forage available.

Introduction: The current generation of 3D printers are lighter, cheaper, and smaller, making them more accessible to the chairside digital dentist than ever before. 3D printers in general in the industrial and chairside setting can work with various types of materials including, metals, ceramics, and polymers. Evidence presented in many studies show that an ideal material used for dental restorations is characterised by several properties related to durability, cost-effectiveness, and high performance. This review is the second part in a 3D Printing series that looks at the literature on material science and applications for these materials in 3D printing as well as a discussion on the potential further development and future evolution in 3D printing materials. Conclusions: Current materials in 3D printing provide a wide range of possibilities for providing more predictable workflows as well as improving efficiency through less wasteful additive manufacturing in CAD/CAM procedures. Incorporating a 3D printer and a digital workflow into a dental practice is challenging but the wide range of manufacturing options and materials available mean that the dentist should be well prepared to treat patients with a more predictable and cost effective treatment pathway. As 3D printing continues to become a commonplace addition to chair side dental clinics, the evolution of these materials, in particular reinforced PMMA, resin incorporating zirconia and glass reinforced polymers offer increased speed and improved aesthetics that will likely replace subtractive manufacturing milling machines for most procedures.

Where are the girls who made history? What evidence have they left behind? Are there places and spaces that bear witness to their memory? Girl Museum was founded in 2009 to address these questions, among many others. Established by art historian Ashley E. Remer, whose work revealed that most, if not all, museums never explicitly discuss or center girls and girlhood, Girl Museum was envisioned as a virtual space dedicated to researching, analyzing, and interpreting girl culture across time and space. Over its first ten years, we produced a wide range of art in historical and cultural exhibitions that explored conceptions of girlhood and the direct experiences of girls in the past and present. Led by an Advisory Board of scholars and entirely reliant on volunteers and donations, we grew from a small website into a complex virtual museum of exhibitions, projects, and programs that welcomes an average 50,000 visitors per year from around the world.

The first International Agricultural Aviation Conference, held at the College of Aeronautics at Cranfield between the 15th and 18th of September 1959, was well timed to mark one stage in the development of the art of airborne farming—it was the stage when the art ceased to be mainly experimental and became essentially a commercial business.Intermittently for the past thirty years, in various parts of the world, attempts have been made with varying degrees of economic and practical success to do certain operations connected with farming, forestry or other allied activities. Two main factors within the past decade have served to intensify the interest and activity in the art. One important factor is the general improvement in aircraft, including helicopters, coupled with the very large number of relatively suitable ones which became redundant (and therefore cheap) at the end of the Second World War. The other factor, equal in importance, concerns the development of the science of agricultural chemistry which has given the farmer a new and wide range of fertilisers, selective weed killers and other chemical forms of pest control which are effective in reasonably small bulk.

AbstractLead (Pb(II)) pollution in water poses a serious threat to human health in many parts of the world. In the past decades, research has been aimed at developing efficient and cost-effective methods to address the problem. In this study, dimethyl sulfoxide (DMSO) and potassium acetate (K-Ac) intercalated kaolinite complexes were synthesized and subsequently utilized for Pb(II) removal from water. The intercalation of kaolinite with DMSO was found to be useful for expanding the interlayer space of the clay mineral from 0.72 to 1.12 nm. Kaolinite intercalation with K-Ac (KDK) increased the interlayer space from 1.12 to 1.43 nm. The surface area of KDK was found to be more than threefold higher as compared to natural kaolinite (NK). Batch experimental results revealed that the maximum Pb(II) uptake capacity of KDK was 46.45 mg g−1 which was higher than the capacity of NK (15.52 mg g−1). Reusability studies showed that KDK could be reused for 5 cycles without substantially losing its adsorption capacity. Furthermore, fixed-bed column tests confirmed the suitability of KDK in continuous mode for Pb(II) removal. Successful application of intercalated kaolinite for Pb(II) adsorption in batch and column modes suggests its application in water treatment (especially removal of divalent metals).

Potential Applications

High-performance anti-wear polyetheretherketone/polytetrafluoroethylene (PEEK/PTFE) blends have drawn much attention over the past few years, owing to their wide range of potential applications. However, a convenient and effective method to prepare such blends with superior mechanical and tribological properties is still lacking. In this work, we propose a promising approach that uses melt-processable PTFE (MP PTFE), instead of conventional PTFE, to prepare anti-wear blends. MP PTFE, with melt flow abilities under appropriate conditions, can disperse homogeneously in PEEK, enhancing both the mechanical and tribological properties of the PEEK/PTFE blend. To prove this postulation, in this work, both MP PTFE and commercial PTFE were blended with PEEK, separately, and the effects of PTFE type and content on the tensile and tribological properties of the blends were studied. The results showed that, although the addition of commercial PTFE to PEEK could increase the wear resistance, it decreased the tensile strength of PEEK significantly. Compared to the blends with commercial PTFE, the blends with MP PTFE exhibited better tribological performance and higher tensile strength for PTFE content below 10 wt%. It was confirmed that the better dispersion of MP PTFE in PEEK endowed the blends with higher tensile strength. The surface analysis indicated that the MP PTFE could readily migrate to and enrich the surfaces of the blends. The relatively high PTFE content on the surface favored the formation of tribo-films, enhancing the tribological properties of the blends.
