Abstract:

Use of clean glassware ensures reliability of analyses that are carried out in laboratories. Glassware should be free of contaminants and residues from previous tests. It is therefore necessary to demonstrate the efficiency of glassware cleaning procedure through validation. This study aims to evaluate the cleaning efficiency of laboratory glassware by quantitation of betamethasone valerate residues in cleaned glassware. Betamethasone ointment was selected through a risk ranking process as the worst to clean product. Glassware used in analysis of this drug product was cleaned manually and residues evaluated using high performance liquid chromatography. The analysis method was validated at concentration levels of 1 - 8 µg/ml for specificity, accuracy, precision, linearity, limit of detection and limit of quantitation. The method demonstrated residue recovery of 97%. Repeatability and inter-mediate precision expressed as relative standard deviation were 1.2% and 1.4%, respectively. The calibration curve was linear over a concentration range from 2.04 to 6.13 µg/ml with a correlation coefficient of 0.9997. The detection limit and quantitation limit were 0.11 µg/ml and 0.34 µg/ml, respectively. No residue was detected in glassware that was sampled for the cleaning validation. The results indicate that the manual cleaning method is effective as the level of betamethasone residues in cleaned glassware was below detection limit and thus will not interfere with analysis of the subsequent analyte.

Abstract:

The author studies the collection of glassware of the 8th–10thcenturies, found in the medieval town of Shamkir, which is located in the western region of the Republic of Azerbaijan. On a functional basis, this collection is represented by tableware, perfumery and drugstore dishes. Drinking vessels prevail among tableware. Perfumery and pharmaceutical utensils are represented mainly by samples of bottles. In the manufacture of glassware, various manufacturing techniques were used, in particular, blowing into a mold and free blasting. The techniques of stretching, welding, polishing, grinding were also used. Glassware of Shamkir belongs to the chemical class Na–Ca–Si with a predominance of the type Na (K)–Ca(Mg)–Al–Si. Most of the glass vessels were decorated with relief geometric ornaments in the form of ovals, circles, and radiating figures, "vortical rosette", "honeycomb" ornaments. The rich raw material resources, professional traditions and innovations which existed here created favorable conditions for the development of glassware production. In the everyday life glassware for various purposes was widely used. Material evidences testify to a great shift in the glass production of Shamkir in the 8th–10th centuries and the production of glassware had a prominent role in the city's economy.

Abstract:

The intent of this study was to evaluate specific technical aspects ofin vitrooocyte maturation (IVM), which included container material and solvent delivery vector. Oocytes were matured in oil-free, open-well systems contained in either plastic or glass dishes and compared to control oocytes matured in media droplets on plastic dishes overlaid with mineral oil. Open-well experiments were repeated with ethanol in a quantity sufficient for delivery of nonmiscible compounds. Cleavage rates were significantly decreased in the glassware system when compared to controls. The plasticware open-well system did not differ from either the controls or the glassware groups. Cleavage in glassware with ethanol was significantly lower than controls or plasticware with ethanol. Blastocyst rates were only decreased in the glassware-ethanol treatment when compared to plasticware-ethanol treatment. Cell counts and percentage of TUNEL-positive cells did not differ significantly. Unexpectedly, sex ratio was significantly decreased (34% male) from the expected value of 50% male in the glassware group with added ethanol. The current study demonstrates the sensitivity of IVM to subtle technical changes, resulting in significant developmental consequences.

Abstract:

Defects in glassware are unacceptable in terms of product strength and aesthetics. The unsmooth cut rim of glassware can often be found in the laser trimming of excessive part after blow molding process. Such defect is basically not safe to use and has to be rejected from the production, thereby inevitably increasing the manufacturing cost and time. Hence, this research aims to reduce the defect in glassware rim induced by the laser cutting process. A wine glass was used as a workpiece sample in this study. Laser power, laser cutting time and workpiece rotational speed were tested and optimized to reduce the defects by using the response surface methodology. The optimum condition for the laser cutting of wine glass was found to be 225-W laser power, 2.4-s cutting duration and 335-rpm rotational speed.

Abstract:

The increased use of video capable cellular phones to document everyday life presents educators with an exciting opportunity to extend this capability into the introductory laboratory. The study assessed whether students enrolled in a southeastern U.S. university's first-year laboratory course retained technical information at a higher rate after creating a technique video. These videos were created on hand-held video capable devices that students owned prior to enrolling in the course, eliminating additional cost to students. Pre-/post-test analysis (N = 509) was performed to determine short- and long-term learning gains regarding reporting the volume of graduated glassware to the proper number of significant figures. Though both groups used various graduated glassware throughout the term, chi-square analysis showed that students who created a video detailing use of a Mohr pipet reported the volume of graduated glassware correctly on the final exam and laboratory practical at a significantly higher rate than those students who received only verbal instruction on the technique.

Abstract:

This article is devoted to the study of the technological features of the manufacturing and decoration of glass vessels from archaeological complex of late Roman time – early Great Migrations period at Viitenky in the East of Ukraine. The observations of the evolution of shapes, decor and individual morphological features of Roman glassware has reached almost a century in their development now. During this time, researchers have repeatedly emphasized their information potential in chronological constructions and searches for production centres of certain types. The technical and technological approach in the study of glass found its place in the investigation of Cherniakhiv antiquities. In our opinion, in combination with traditional archaeological methods, it remains one of the most promising ways to resolve the issue of the origin of Cherniakhiv glass vessels, even today. The purpose of our study is a comparative analysis of the technological features of glassware from Viitenky, vessels from the area of the Cherniakhiv culture in Ukraine and items from the Roman provinces. The analysis of the materials allows drawing some conclusions. The set of technological methods registered during the study of glassware from Viitenky finds parallels both among Cherniakhiv glass vessels and among provincial Roman vessels. However, some of them are asynchronous to those existing in the provinces in late Roman and late Antique times. Despite the fact that the same morphological and decorative elements occur both among barbarian cups and among vessels of the Provincial-Roman circle, the chronology of their existence in both categories of Cherniakhiv glassware is often different. Observations of the chronology of their existence among Cherniakhiv vessels on the territory of Ukraine suggest certain changes in the set of technological methods used for their manufacturing and decoration, which appear no earlier than in the middle of the 4th century.

Abstract:

The Silk Road served as a conduit for cultural exchange between ancient East and West, with glass being a valuable material evidence of early trade interactions. Archaeologists have classified ancient glassware primarily into two categories: high-potassium glass and lead-barium glass. This study focuses on the sub-classification of high-potassium glass. Firstly, the high-potassium glass is divided into two major categories, weathered and unweathered, based on their weathering properties. Subsequently, the R-Q clustering algorithm is employed to further subdivide the unweathered high-potassium glasswhile the same approach is applied to the weathered high-potassium glass. The results are validated through rational analysis and can be applied to other types of ancient glassware.

Abstract:

Background: Age-Related Hearing Loss (ARHL) is a gradual and irreversible age-dependent decline in auditory function. There is still no consensus on the long-term functional effects of noise exposure on ARHL. Objective: This study aimed to compare the prevalence of ARHL in an elderly population occupationally exposed to noise in a non-exposed population. Methods: The population was divided into two groups: a group of 482 subjects professionally exposed to noise for over 10 years and a group of 1129 non-exposed subjects. Among the exposed subjects, a subgroup of 298 who worked for over 10 years in the glassware industry was selected. All the participants underwent a thorough otorhinolaryngological examination. Results: The presence of ARHL was found in 81% of exposed subjects and in 4% of non-exposed subjects. In the sub-group of glassware workers, the prevalence was 88%. The statistical analysis showed a significant association between previous occupational exposure to noise and ARHL (OR = 1.09; 95% CI = 1.067-1.124; p = 0.0012) and between exposure to the glassware industry and ARHL (OR = 1.89; 95% CI = 1.78-1.96; p = 0.006). Conclusion: Consistent with recent studies, we found a significantly higher prevalence of ARHL among workers exposed to noise; however, further studies are needed to support these findings.

Abstract:

As a precious item in the foreign trade along the Silk Road, it is of great significance to analyze the composition and identify the type of glass relics. In this paper, through the training of random forest, the characteristic importance of each index is obtained, and the classification rule is obtained. It is determined that lead oxide (PbO) is the most important index in the classification of glass types. Then, the k value was determined by the elbow principle, and k=5 was selected as the cluster type. After that, k-means clustering was carried out on the high potassium and lead barium glass respectively to get the classification results, which were divided into 5 subclasses. Due to the small amount of data, in the random forest model, the robustness of the model is constantly enhanced through multiple hyperparameter tuning. In the trained random forest model, it is found that the results do not change, which proves the model is reasonable. At the same time, the correlation between the chemical components of the glass cultural relics samples of different categories was analyzed, and the difference of the correlation between the chemical components of different categories was compared.

Abstract:

The trace amounts of lead in extraction glassware products were determined by potentiometric stripping analysis with constant inverse current in the analytic step (PSA-iR), an electrochemical technique of high sensitivity and selectivity. This paper deals with an investigation which was directed to the effect of a great number of factors on the results of PSA-iR, of lead in glassware, such as the mercury time electrodeposition, the electrolysis potential, the solution stirring rate and the constant inverse current. Linearity of the lead analytical signal was achieved within the range of mass concentrations from 2.5 ?g/dm3 to 4.5 ?g/dm3.Adetection limit of 0.64 ?g/dm3 was obtained, with a reproducibility of 4.14 % expressed as the coefficient of variation. The analyses were carried out using a computerized stripping analyzer of domestic design and manufacture (Faculty of Technology, Novi Sad and "Elektrouniverzal", Leskovac). The accuracy of the method was confirmed by parallel analyses using flameless atomic absorption spectrophotometry as the reference method.

Abstract:

As you know, laboratory-diagnostic glassware used in medicine is mainly made of polyethylene and polypropylene, transparent polystyrene and other polymers with the properties necessary for use in laboratory conditions. The advantages of plastic laboratory glassware are obvious: products made of it are lightweight, durable, besides, they do not react with urine of any acidity level and have no impurities. The presence of the label allows you to write the necessary data about the patient, which is also provided for by the instructions for sending the material to the laboratory. It is important for manufacturers that after sterilization the physical and mechanical indicators remain at a high level, and also the change in the color of the product turns out to be of no small importance. In the work, injection molded polypropylene grades were studied, which can be used as a material for laboratory-diagnostic glassware: Balen 01270, manufactured by JSC Ufaorgsintez, (PP 01270); Balen 1030, manufactured by JSC Ufaorgsintez, (PP 1030); H 250 GP / 3, produced by LLC Tobolsk-Polymer, Sibur Holding, (PP H 250 GP / 3); H 250, LLP "Company Neftekhim LTD", (PP 250). It was found that the greatest increase in MFI is observed for polypropylene of the Balen 1030 grade, increasing by 27.5 times. The smallest increase in MFI is observed for grades H 250 GP/3 and H 250 by 1.5-1.7 times. With an increase in the absorbed dose, the viscosity naturally increases due to the destruction of PP. The color practically does not change with an increase in the radiation dose. For PP H250. Recommended for manufacturers of medical devices PP H 250 grade polypropylene.

Abstract:

Introduction. Heavy metals are included in one of the significant groups of ecotoxicants. Determining heavy metals at low levels is one of the main problems in analytical chemistry, which depends on various factors. Ignoring the contribution of these factors to the total uncertainty can increase the probability of distortion of the results due to an erroneous decision on the compliance of the obtained data with a particular standard. The most significant influences include the purity of reagents, dishes, and air in laboratory rooms. Purpose of the work. Search for ways of reducing the listed influences provided that the expense of time, material and labour resources are minimized. Materials and methods. In the course of the work, many experiments were carried out, including the analysis of nitric acid for the content of metals before and after cleaning by distillation, the analysis of washes from new fluoroplastic laboratory glassware and glassware that had been cleaned by steaming, an assessment of the effect of air pollution in the laboratory room based on a study of calibration curves, which were constructed at the analysis of standard iron solutions prepared in the Clean Workplace and in a conventional fume hood. All measurements were performed by inductively coupled plasma mass spectrometry on Agilent 7800 ICP-MS mass spectrometer. Results. The efficiency of the proposed methods for eliminating interfering influences on the analysis has been experimentally proved. Conclusion. The technical and analytical problem, which consists of finding optimal conditions for preparation of reagents, glassware cleaning and decreasing the influence of laboratory air pollution, allows to increase reliability of the obtained results and prevent distortion of information about the observed degree of environmental pollution.

Abstract:

The period of High Middle Ages witnessed the development of glassmaking in Central Asia. The paper presents glass articles from pre-Mongolian Penjikent and its suburbs. The Penjikent col- lection contains all major groups of glass articles recognized in the functional classification tradi- tionally used in the region: table glassware (fig. 1; 2; 3, 1–7; 4, 1, 2; 5, 8; 6, 15, 17), perfume and drug jars (fig. 2, 13; 5, 4–7, 9, 10), chemical glassware (fig. 4, 7), household items (fig. 3, 6; 4, 3–5; 5, 1–3; 6, 16), adornments (fig. 5, 11–13) and window-glass (fig. 6, 1–14). The material under study can be dated to the X–XII cc. These glass articles find analogies in the materials from Samarkand, Tash- kent oasis, Bukhara, Fergana valley, Northern Tokharistan, as well as some synchronous urban centers on the territory of modern Kazakhstan. There is also a tendency to a certain uniformity (fashion) in the main types of glass articles that were produced during that period in both Central Asia and the Near East.

Abstract:

Abstract Methods for determination of trace levels of phthalate esters In environmental samples require procedures that avoid the Introduction of laboratory contaminants. Because It Is difficult to avoid contamination of samples with phthalate esters from laboratory reagents, materials, and glassware, we have undertaken a study to determine the sources, extent of contamination, and conditions under which background contamination can be minimized. Solvents such as acetone, hexane, diethyl ether, isooctane, and methylene chloride, and reagent water samples from various commercial suppliers were analyzed for 11 phthalate esters. Florlsll, alumina, silica gel, anhydrous sodium sulfate, filter paper, paper thimbles, glass wool, and aluminum foil were washed with organic solvents and the solvent washings were analyzed for 11 phthalate esters. Finally, we addressed the likelihood of contamination of laboratory glassware subjected to common laboratory cleanup procedures and the likelihood of contamination of hexane and Isooctane stored In sample vials of different sizes. The present study was conducted in conjunction with the single-laboratory evaluation of U.S. Environmental Protection Agency (EPA) method 8060 for determination of phthalate esters in environmental samples.
