Two Parameters

This study compared two harvesting techniques (manual and mechanical) and three grape sorting methods (no sorting, manual, and densimetric) in attempts to obtain high-quality must. The trials were carried out in 2009 and 2010 in Tuscany, Italy. The effectiveness of the harvest-sorting chain was assessed on two parameters. Substandard berries (SSB) is the percentage of berries, which do not meet quality standards that enter the winemaking process, and material other than grape (MOG) is a measure of the cleanliness of the berries entering the process. In the two years the trial was run the grape maturation level was widely different; in 2009 the vintage was more far mature than in 2010. With respect to SSB content and harvesting methods, in 2009 (more mature grapes) hand-picking reduced SSB content, while in 2010 there were no differences between the two harvesting methods. In both years, densimetric sorting reduced SSB content, while there were no significant differences between no sorting and manual sorting. In terms of MOG content, both harvesting and sorting results were inconsistent. In 2009, MOG was lower in mechanically harvested grapes; while in 2010 it was lower in hand-picked grapes. As for sorting methods, in 2009 there were no differences in MOG, while in 2010 mechanical sorting produced better results. Our results question whether the post-harvest sorting techniques used by many estates are effective; particularly as the question has received little attention and no previous research has compared methods. Secondly, our study contributes to the debate on the effects of harvesting technique on wine quality.

Automatic Removal

The roller and sieve machines most commonly used in Russia for the post-harvest processing of root and tuber crops and onions have a number of disadvantages, the main one being a decrease in the quality of sorting due to the contamination of working bodies, which increases the quantity of losses during sorting and storage. To obtain high-quality competitive production, it is necessary to combine a number of technological operations during the sorting process, such as dividing the material into classes and fractions by quality and size, as well as identifying and removing damaged products. In order to improve the quality of sorting of root tubers and onions by size, it is necessary to ensure the development of an automatic control system for operating and technological parameters, the use of which will eliminate manual sorting on bulkhead tables in post-harvest processing. To fulfill these conditions, the developed automatic control system must have the ability to identify the material on the sorting surface, taking into account external damage and ensuring the automatic removal of impurities. In this study, the highest sorting accuracy of tubers (of more than 91%) was achieved with a forward speed of 1.2 m/s for the conveyor of the sorting table, with damage to 2.2% of the tubers, which meets the agrotechnical requirements for post-harvest processing. This feature distinguishes the developed device from similar ones.

The Cost

Background Vitamin and mineral premix is one of the most significant recurring input costs for large-scale food fortification programs. A number of barriers exist to procuring adequate quality premix, including accessing suppliers, volatile prices for premix, lack of quality assurance and monitoring of delivered products, and lack of funds to purchase premix. Objective To develop and test a model to procure premix through a transparent and efficient process in which an adequate level of quality is guaranteed and a financial mechanism is in place to support countries or specific target groups when there are insufficient resources to cover the cost of premix. Methods Efforts focused on premixes used to fortify flour, such as wheat or maize (iron, zinc, B vitamins, and vitamin A), edible oils (vitamins A and D), and other food vehicles, such as fortified complementary foods, complementary food supplements, and condiments. A premix procurement model was set up with three distinct components: a certification process that establishes industry-wide standards and guidelines for premix, a procurement facility that makes premix more accessible to countries and private industry engaged in fortification, and a credit facility mechanism that helps projects finance premix purchases. Results After three years of operation, 15 premix suppliers and 29 micronutrient manufacturers have been certified, and more than US$23 million worth of premix that met quality standards has been supplied in 34 countries in Africa, Central and Southern Asia, and Eastern Europe, reaching an estimated 242 million consumers. Conclusions The Premix Facility demonstrated its effectiveness in ensuring access to high-quality premixes, therefore enabling the success of various fortification programs.

This study considers the question whether the changes in Accounting Standards has led to companies making less use of earnings management. The paper is an attempt to investigate whether the application of high quality standards like International Financial Reporting Standards (IFRS) is related to high financial reporting quality. This study addresses this issue empirically. Furthermore, this research examines whether German companies that have applied IFRS have less earnings management compared to German companies that report according to the German Generally Accepted Accounting Principles (GGAAP). The sample, consisting of two equally large listed companies in Germany (Südzucker Group and Henkel Group) from 2003-2014. The study suggests that IFRS-adopters show different earnings management performance compared to companies reporting under German GAAP. This finding contributes to the discussion on whether high quality standards are appropriate and operational in countries with weak investor protection rights. The result shows that adopters of IFRS in Germany can be related with less use of earnings management as a result of changes in accounting standards. This result is contradictory with previous research that was done by Van Tendeloo and Vanstraelen, (2005), and consistent with the previous research conducted by Ball et al. (2003).

This paper aims to synthesise, characterise and find out the properties of a model dye for convenient union dyeing of wool, polyester and wool/polyester blend fabric compared with C.I. Disperse Yellow 23. The reactive disperse dye was prepared containing sulphatoethylsulphone (SES) as a reactive group. The dye was synthesised by diazotization and coupling reaction. Firstly, we synthesized azo dye intermediate I using 1-aminobenzene-4-sulphatoethylsulphone diazotized and then coupled it with aniline. The synthesized azo dye intermediate I was diazotized and coupled with phenol to give dye 2. Different factors affecting the dyeability and fastness properties of SES dye 2 were thoroughly investigated on wool, polyester and wool/polyester blend fabrics in comparison with C.I. Disperse Yellow 23 dye 1. Maximum exhaustion and total fixation yield using sulphatoethylsulphone (SES) dye 2 were achieved on wool fabric at neutral pH 7. The dye showed high dyeing performance due to its nonionic reactive VS derivative. The dyeing results indicate high quality dyeing properties

Nanoparticles have a great prospect for therapeutic applications. They can protect drugs under physiological conditions and act as a matrix for directed delivery of drugs, e.g., to a specific tissue or cell type. Polymer-based nanomaterials are considered as highly effective in this regard. Their properties can be tailored to meet specific demands for given therapeutic purposes. Considering the high-quality standards placed on medical products, the question arises: Which type of polymer material should be employed? One might select synthetic polymer compounds, which are highly diverse in terms of the molecular structures and supramolecular architectures that can be created, or biopolymers such as polysaccharides that are renowned for their native biocompatibility.
