Determinant Factors in Purchasing Korean Skin Care Products

2020

The demand and business opportunities in the skin and facial beauty sector have increased in the last 10 yr. The beauty and personal care industry in Indonesia grows on average of 12 %, with a market value of 33 × 109. This research emphasizes the presence of the influence of attitude, subjective norm, and perceived behavioral control on the purchase intention of skincare products that are moderated by the country of origin. The data collection is conducted by distributing questionnaires to a total of 130 respondents. Data obtained through a questionnaire are then processed with Smart Partial Least Square (PLS). The results in this study prove that the attitude and perceived behavioral cont…

Vergleich der prognostischen Aussagefähigkeit der Catterall- und Herring-Klassifikation bei Patienten mit Morbus Perthes

2008

QUESTION Investigation of the predictive value of the Catterall- as compared to the Herring-classification in patients with Perthes disease. METHOD A radiological follow-up study including 53 patients with a total of 59 affected hips was carried out. In the initial diagnosis the Catterall-, Waldenstrom- and Herring-stages were assessed. The epiphyseal ratio, the head-neck ratio and the lateral subluxation were measured and compared at the time of diagnosis, fragmentation stage and in a follow-up examination, which was carried out 4, 9 years after diagnosis on the average. The results of the follow-up examination were assessed using the Mose-classification and compared as well. In addition t…

Intraductal aspiration: a promising new tissue-sampling technique for the diagnosis of suspected malignant biliary strictures

2012

Brushing is the most commonly used technique for biliary sampling at ERCP, despite its limited sensitivity. To evaluate intraductal aspiration (IDA) as a new combined endoscopic technique for cytodiagnosis, its cellular adequacy, diagnostic accuracy for cancer detection, feasibility, and safety. Prospective, observational study. Single tertiary referral center. IDA cellular adequacy, diagnostic accuracy for cancer detection, feasibility, and safety. From April 2009 to September 2010, 42 consecutive patients with suspected malignant biliary stricture underwent ERCP, with tissue sampling obtained with IDA. IDA included performance of standard brushing in all patients. After standard brushing,…

Molecular Search of New Active Drugs AgainstToxoplasma Gondii

1999

Molecular connectivity has been applied to the search of new compounds with activity against the protozoan Toxoplasma gondii, using a stepwise linear discriminant analysis (SLDA) which is able to classify a compound according its activity either as active or as inactive. Among the selected compounds, andrographolide and dibenzotiophene sulfone stand out, both with IC50 values lower than 1 microgram/ml, which are comparable to these of drugs such as sulfamethoxazole, pyrimethamine and trimethoprim, with IC50 values equal to 1.1, 0.04 and 2.31 micrograms/ml, respectively. These results confirm the usefulness of our topological approach for the selection and design of new-lead drugs active aga…

Critical current modulation induced by an electric field in superconducting tungsten-carbon nanowires

2021

The critical current of a superconducting nanostructure can be suppressed by applying an electric field in its vicinity. This phenomenon is investigated throughout the fabrication and electrical characterization of superconducting tungsten-carbon (W-C) nanostructures grown by Ga+ focused ion beam induced deposition (FIBID). In a 45 nm-wide, 2.7 μm-long W-C nanowire, an increasing side-gate voltage is found to progressively reduce the critical current of the device, down to a full suppression of the superconducting state below its critical temperature. This modulation is accounted for by the squeezing of the superconducting current by the electric field within a theoretical model based on th…

An analysis of feed’in tariffs for solar PV in six representative countries of the European Union

2014

Abstract In this paper, after a brief review on the main support policies for Photovoltaic (PV) systems in Europe, the specific situations of six representative countries (France, Germany, Greece, Italy, Spain and the U.K.) are examined, with the purpose of highlighting the main differences in the implementation of the feed’in tariff (FiT) support policies adopted for PV systems. In particular, a comparison based on the calculation of economic indexes, as the Discounted Cash Flows (DCF), the Pay-Back-Period (PBP), the Net Present Value (NPV) and the Internal Rate of Return (IRR), for different sized PV systems shows that a specific FiT can sometimes be inconvenient for the producer and that…

Comparative analysis of different supporting measures for the production of electrical energy by solar PV and Wind systems: Four representative Europ…

2009

Abstract In the 9th of March 2007, the European Council decided a fixing goal of 20% contribution of the renewable energy sources (RES) on the total European electric energy production in 2020. In order to reach such an ambitious goal, all the European countries are adopting different support policies for encouraging the installations of RES-based generation systems. In this paper, after a brief review on the main support policies for RES in Europe, the specific situations of four representative countries (France, Germany, Italy and Spain) are examined, with the purpose of putting into evidence the main differences in the support policies adopted for Photovoltaic (PV) and Wind systems. In p…

Determination of the object surface function by structured light: application to the study of spinal deformities.

1999

The projection of structured light is a technique frequently used to determine the surface shape of an object. In this paper, a new procedure is described that efficiently resolves the correspondence between the knots of the projected grid and those obtained on the object when the projection is made. The method is based on the use of three images of the projected grid. In two of them the grid is projected over a flat surface placed, respectively, before and behind the object; both images are used for calibration. In the third image the grid is projected over the object. It is not reliant on accurate determination of the camera and projector pair relative to the grid and object. Once the met…

Surface sulci in squeezed soft solids

2013

The squeezing of soft solids, the constrained growth of biological tissues, and the swelling of soft elastic solids such as gels can generate large compressive stresses at their surfaces. This causes the otherwise smooth surface of such a solid to become unstable when its stress exceeds a critical value. Previous analyses of the surface instability have assumed two-dimensional plane-strain conditions, but in experiments isotropic stresses often lead to complex three-dimensional sulcification patterns. Here we show how such diverse morphologies arise by numerically modeling the lateral compression of a rigidly clamped elastic layer. For incompressible solids, close to the instability thresho…
