We already know a lot about the world around us and, in general terms, understand how things work. Of course, some problems have not yet been solved: the behavior of black holes, the mysteries of quantum entanglement, the transparency of dark matter. It is not clear how life arose from dust. However, we hope to eventually understand everything that we do not yet understand, because we believe in the power of our minds. But the problem of the mind itself stands apart. There is nothing more complex in the world than consciousness. Here we have to comprehend ourselves and it is not entirely obvious that this is possible. Let's say the meat grinder is quite primitive, but she doesn't know it.

This paper covers the validation and measurement uncertainty evaluation of an ICP-AES method for bismuth mass fraction determination in bismuth sulfide thin films. Plasma view at radial mode and the wavelength were monitored for bismuth at 223.061 nm. Following AFNOR (Association Française de Normalisation) Norm NFT 90-210 (2009), a regression equation was calculated using single element bismuth standard solution prepared in the same matrix as samples. The linear range was between 0.2 and 2.0 mg L−1. Limits of detection (LOD) and quantification (LOQ) were calculated as 0.03 and 0.12 mg L−1, respectively. Recovery percentages were ranging between 91 and 109 %. Accuracy was found to be adequate. Estimated expanded uncertainty according to both GUM and EURACHEM guides was 3.1 %.

Ruthenium, Antimony and Vanadium doped and undoped tin oxide (SnO2) thin films were prepared by the R.F. Sputtering method. At the beginning of the thin film production studies, pellets were formed by pressing the filled and undoped tin oxide powders in the laboratory environment. The purpose of creating these pellets is to replace commercially purchased target material that acts as the coating material in the sputter coating device. The aim of the study is to use these pellets instead of this commercial target due to its disadvantages such as long lead time and expensiveness, and thus to produce easier, more diverse and high quality thin films. This study includes the synthesis of pure and doped thin films of tin oxide semiconductor material, which has a wide band gap and attracts attention with its wide spread use thanks to this feature, subjecting it to annealing process under different temperatures and times, and structural and morphological characterization studies: XRD, SEM, AFM, XPS, UV-Vis Spectrophotometer and Nano-hardness machine. The study showed that doped and undoped tin oxide films showed similar properties to similar studies seen in the literature, so that the pellets formed in the laboratory environment functioned. No major structural difference was observed in the films produced as a result of the use of pellets and target. As a result of the findings of the study, it has been seen that it is a preliminary study for the investigation of gas sensing properties.

Semen preservation technique includes chilling at 4-5 oC and cryopreservation at -196 oC. The role of extender enriched with protectant is essential for storing sperm. In order to evaluate the effects of different concentrations of soybean lecithin (SL) in Tris-based extender on quality parameters of chilled canine semen and subsequent potential. The Trisbased extenders with 0.5%, 1.0% or 2.0% SL (w/v) were used to store the sperm of French Bulldog; meanwhile, Tris-based extenders supplemented with 20.0% (v/v) egg yolk (EY) were used as the control group. Sperm samples in each group were stored at 4⁰C for 168 hours period.

A simple High-Performance Thin layer chromatography (HPTLC) method has been developed for determination of atenolol in human blood and viscera. The mobile phase was ethyl acetate, acetone, ethyl alcohol, ammonia solution in the ratio of 45:45:7:3. The densitometry scanning at 254 nm was found to be maximum absorption for standard atenolol. The standard and extracted atenolol from samples were detected by HPTLC and confirmed with authenticated spectra at 254 nm. The quantity of the atenolol determined to be 1.6 µg for viscera and 1.5 µg for blood sample.

Infrared (IR) photography has been shown to be a proficient technique for the examination of documents, blood traces and ageing of skin injuries. However, its application in relation to the visualisation of latent Gunshot Residue (GSR) deposits has, until now, been significantly under researched. This paper evaluates the effectiveness of IR photography as a rapid technique for GSR visualisation on different fabric types.

The objective of this work is to investigate the influence of sodium on the characteristics of Cu(In,Ga)Se2 (CIGS) thin films prepared by a three-stage deposition process with a MoNa back contact, in comparison to Mo/SLG. The XRD results show that all the CIGS thin films deposited onto Mo/SLG substrates have the (112) preferred orientation, rather than the (220/204) orientation of CIGS deposited onto Na-free substrates.

To determine the proportion of human milk (pooled and homogenized) fat loss via feeding tube in a simulated 24-hour feeding cycle. Anonymous samples of frozen human milk were obtained, thawed and pooled (pHM) in a 1000 mL glass beaker with a magnetic stir bar. Eight syringes (30 mL each) were prepared and attached to 60” extension tubing and a 5 FR polyurethane or silicone nasogastric (NG) tube. Samples to test for pool uniformity were collected at the beginning, middle and end of syringe preparation. Milk was delivered sequentially via gravity, 30-minute or 60-minute infusion. Pooled human milk was analyzed for macronutrient content at the end of each feeding “cycle”. All scenarios were repeated using homogenized donor human milk (hDHM).

This article presents a human terrain analysis of the Islamic radicalization occurring in Latin America and the infiltration of the Al-Qaeda terrorist network into the country of Brazil. The study used sociological investigative research methods conducted in Brazil, extensive ethnographic interviews collected in the major Brazilian cities of Sao Paulo and Rio de Janeiro, and intensive Brazilian Portuguese language immersion. The ethnographic research techniques examined the social, political, religious, and linguistic structures to gain an understanding of how Al-Qaeda operatives have established an operational base in Brazil. The study provides an early warning sociological intelligence assessment of the threat of radical Islam in Latin America.

France, Greece, Italy, and Spain the major sheep and goat milk producers in Europe, got the initiative through an interim of 30 years (1985 – 2015), to organize - through IDF - 7 symposiums aiming at the upgrade of the Dairy Sector. One major interest was the milk quality. Stepwise, the efforts followed cow milk structural development in organizing the testing laboratory, the definition of quality in composition (fat, protein, lactose, total solids), in Hygienic (Total Bacteria Count, Somatic Cell Count, antibiotics residues and Aflatoxin M1 contamination), adulteration with water and detection of milk species. EU, by Decision 2002/657/EC, defined the rules for the Directive 96/23/EC, enumerated the testing methods, the demands in sampling procedures, the minimum limits of performance, the quality control (ISO 17025) and the interpretation of results. The equivalency of results from different laboratories, through ISO 17025, demanded the application of ISO analytical standards.

The anodization of aluminum foils having micrometer thickness is a common process and results in hexagonally self-ordered alumina membranes. However, anodic aluminum oxide (AAO) membranes fabricated from nanometer-thin films present new challenges to the anodization process, since aluminum films adheres poorly on supporting substrates and the smoothness of the film is highly related to the kind of substrate.
