AbstractOver the last dozen years, the topic of small and medium enterprise (SME) default prediction has developed into a relevant research domain that has grown for important reasons exponentially across multiple disciplines, including finance, management, accounting, and statistics. Motivated by the enormous toll on SMEs caused by the 2007–2009 global financial crisis as well as the recent COVID-19 crisis and the consequent need to develop new SME default predictors, this paper provides a systematic literature review, based on a statistical, bibliometric analysis, of over 100 peer-reviewed articles published on SME default prediction modelling over a 34-year period, 1986 to 2019. We identified, analysed and reviewed five streams of research and suggest a set of future research avenues to help scholars and practitioners address the new challenges and emerging issues in a changing economic environment. The research agenda proposes some new innovative approaches to capture and exploit new data sources using modern analytical techniques, like artificial intelligence, machine learning, and macro-data inputs, with the aim of providing enhanced predictive results.

The possibility that marine invertebrates might obtain part of their nutritional requirements by direct absorption of dissolved molecules through the epidermis has recently received considerable attention. This revival of interest in a field which had been virtually abandoned since the early part of the century was led by the findings of Stephens & Schinske (1957, 1958, 1961). Modern analytical techniques have revealed that the amount of dissolved nutrients in coastal waters is much greater than was formerly realized; total amino acids have been recorded in concentrations of up to 10-4 mole/litre in south-east Alaskan waters (Schell, 1974) and 7 x 10-5 mole/litre off Helgoland (Bohling, 1970). Direct absorption of amino acids has been conclusively established in several phyla (see reviews by Stephens, 1968,1972), and one of the major aims of current research is to show that dissolved organic molecules taken up from available concentrations could be of nutritional significance. Recent developments concerning the possible roles of uptake in marine ecosystems have been reviewed by West, de Burgh & Jeal (1977).

ABSTRACTAt Cornell University we are in the third year of teaching an interdisciplinary, undergraduate course on the physical properties and structures of works of Art, and the modern analytical methods used to investigate them: Art, Isotopes, and Analysis. The challenge is to explain concepts familiar to museum scientists and conservators to a group of 150 undergraduate students with a background that ranges from Art History to Computer Science. Painting techniques (Fresco, Tempera, Oil, etc.) are demonstrated to the class. The analytical techniques involve the interactions of electrons, photons, ions and neutrons with pigments and other materials. This instructional approach serves as an introduction to published analyses of works of art.

Linezolid is a potent synthetic oxazolidinone used for the treatment of bacterial infections with a new mechanism of action that involves early inhibition of bacterial protein synthesis. In humans, linezolid circulates mainly as parent drug and is excreted primarily as parent drug and a major inactive, morpholine ring-opened carboxylic acid metabolite. In vitro studies were conducted to identify the hepatic enzymes responsible for the oxidative metabolism of linezolid using human liver microsomes. However the specific enzyme responsible for the oxidation of linezolid was not identified. The present study is to check with and identify the probable metabolic pathways in various species like monkey, mouse, rat, dog and human livermicrosomes and put up the best model for the contingency studies using modern analytical techniques. The current investigation on the metabolites obtained after 60 minutes incubation revealed three additional metabolites, namely, M10, M11 and M12, adding on to the list of already reported metabolites.>

Abstract The tools of analytical chemistry, and the expertise and enthusiasm of many of its practitioners, have had a profound influence in the field of cultural heritage [1, 2]. Analytical techniques, especially those involving non-destructive methods of examination, have played a key role in the characterization, restoration, and preservation of an incredible range of works of art and cultural heritage, including ceramics, textiles, paintings, books, drawings, sculptures, jewelry, and a myriad of artifacts made of glass, wood, or metal. In addition, modern analytical instrumentation has been successfully applied to study the techniques used to produce heritage materials, to verify the authorship or estimate the date of pieces of art, and to detect reproductions and forgeries.

Epidemiological studies on the heavy and toxic metal content in the human blood and hair of some smokers from Saudi Arabia were carried out by modern analytical techniques. The levels of some selected heavy and toxic metals (e.g.; Hg, Pb, Cd, As, Se, Mn, Zn, Ni, and Cr) were determined using inductively coupled plasma-atomic emission spectrometer (ICP-AES). Prior to the analysis, the blood and hair samples of Saudi Arabia smokers were collected, treated, and digested by microwave digestion system. The number of cigarettes per day as well as the smoking period was taken in consideration in this study. The tested elements concentrations in the investigated smoker blood and hair samples were compared with those obtained from some nonsmoking control samples. The samples were collected from the psychiatric hospital in Taif city after issuing the ethical committee license in this regard. The results obtained from this study represent a very important guide for the antismoking organizations. The assessment of some side effects of the smoking in such studies presents vital challenge for the social antismoking authorities and the stakeholder governments to attain the sustainable investment for their people.
