The 19Th Century

Hydrophobic oil droplets, particles and air bubbles can be dispersed in water as kinetically stabilized dispersions. It has been established since the 19th century that such objects harbor a negative electrostatic potential roughly twice larger than the thermal energy. The source of this charge continues to be one of the core observations in relation to hydrophobicity and its molecular explanation is still debated. What is clear though, is that the stabilizing interaction in these systems is understood in terms of electrostatic repulsion via DLVO theory. Recent work [Carpenter et al., PNAS 116 (2019) 9214] has added another element into the discussion, reporting the creation of bare near-zero charged droplets of oil in water that are stable for several days. Key to the creation of the droplets is a rigorous glassware cleaning procedure. Here, we investigate these conclusions and show that the cleaning procedure of glassware has no influence on the electrophoretic mobility of the droplets, that oil droplets with near-zero charge are unstable, and provide an alternative possible explanation for the observations involving glass surface chemistry.

The accumulation of knowledge about the structure and functions of the epidermis will make it possible to solve the most important practical tasks of forming the animals’ productivity and health. Two breeding groups have been researched: 1) purebred young boars, 2) young boars with the blood of Finnish Landrace. The studies were carried out when the animals reached live weight of 100 kg, and the control slaughter was made. The results of the Poltava Meaty Breed pigs’ skin epidermal barrier research made it possible to trace significant differences in the ratio of the main epidermis layers in animals of different genotypes. The genotype influence was 15.45 %. An-imals with the blood of the Finnish Landrace have lower biological possibilities for life in the given climatic and technological conditions, that is, they are less promising for further breeding work.

ABSTRACT Cupuaçu (Theobroma grandiflorum Schum.) is an exotic fruit with a promising economic potential, particularly due to its strong aroma and creamy texture. This study aimed to produce sweetened cupuaçu puree and evaluate the effects of packaging corrosion on its sensory properties and shelf-life in tinplated cans. After 240 days of storage, the commercially sterile product had average sensory analysis scores of 5.89 ± 0.21, 5.39 ± 0.30, 5.45 ± 0.21 and 5.49 ± 0.25, for appearance, aroma, flavor and overall appreciation, respectively. Sensory acceptance scores did not change during storage (p>0.05). Corrosion potential and low tin and iron levels in the product, which are parameters used to evaluate food-packaging interaction, demonstrated the product remained food-safe throughout its shelf-life. Tinplate is a promising packaging material for sweetened cupuaçu puree due to its mechanical and protective properties. Furthermore, tin plating is an economically viable food technology to extend the shelf-life of cupuaçu products and expand its domestic and international markets.

The saw stability in operation defines the ability of the saw blade to resist the forces acting on it in the plane of greatest rigidity. The saw can work reliably only in case of maintaining stable balance, which is achieved through the creation of normalized residual stresses in certain zones of the saw blade by different methods. The stresses balance the forces of external influences. Compressive stresses are created in the central part of the blade to make the circular saw operational. These stresses compensate the forces of centrifugal acceleration, temperature heating of individual zones of the saw blade, external longitudinal and transverse bending forces arising in material processing. In practice, the creation of normalized stresses in the saw disk is traditionally carried out only by local mechanical contact action (forging, rolling) of the saw blade tool on the steel saw blade. It is proposed to form the stressed state of the disk by thermophysical action instead of the traditional mechanical processing of the saw blade. The thermophysical action involves the creation of normalized residual stresses in the saw blade by the concentrated thermal exposure to local differently directed narrow-band zones of straight or deflected shape, mainly radial or along concentric traces, controlling the process in real time. A new approach to the formation of residual stress fields in the saw blade by thermoplastic action enables to radically change the settingup procedure of the circular saw, ensuring its stability in operation.

This chapter examines how London had to learn to be colonial. From the very first moments of sustained encounter in the late sixteenth century, places like Ossomocomuck and London were entangled through the creation of knowledge. Even before explorers stepped ashore in “Virginia,” they were propelled there by an unprecedented urban crisis that threatened the stability of London society. This urban context shaped how English explorers and colonists saw the territories and people they encountered and how they attempted—often unsuccessfully—to organize themselves and others in these unfamiliar places. Meanwhile, the experiences of Indigenous travelers to London, and in particular those originating in the homelands of the eastern Algonquian peoples suggest that parallel Indigenous processes of exploration were taking place.

Mycotoxins are widely studied by many research groups in all aspects, but the stability of these compounds needs further research for clarification. The objective of this study is to evaluate deoxynivalenol and zearalenone stability during all steps of the malting and brewing processes. The levels of these compounds decreased significantly during the production process (barley to beer). During the malting process, the DON levels decreased significantly in the steeping, germination, and malting steps (62%, 51.5%, and 68%, respectively). Considering ZEN, when the levels were compared between barley and the last step of the process, a significant decrease was observed. Most of the mycotoxins produced were transferred to the rootlets and spent grains, which is advantageous considering the final product. Furthermore, the mycotoxin dietary intake estimation was included in this study. The results proved that if the concentrations of target mycotoxins in raw material are under the limits established by the regulations, the levels decrease during the malting and brewing processes and make the beer secure for consumers. The quality of the five commodities involved in the beer process plays a decisive role in the creation of a safe final product.

OBJECT A range of surgical options exists for the treatment of degenerative lumbar spondylolisthesis (DLS). The chosen technique inherently depends on the stability of the DLS. Despite a substantial body of literature dedicated to the outcome analysis of numerous DLS procedures, no consensus has been reached on defining or classifying the disorder with respect to stability or the role that instability should play in a treatment algorithm. The purpose of this study was to define grades of stability and to develop a guide for deciding on the optimal approach in surgically managing patients with DLS. METHODS The authors conducted a qualitative systematic review of clinical or biomechanical analyses evaluating the stability of and surgical outcomes for DLS for the period from 1990 to 2013. Research focused on nondegenerative forms of spondylolisthesis or spinal stenosis without associated DLS was excluded. The primary extracted results were clinical and radiographic parameters indicative of DLS instability. RESULTS The following preoperative parameters are predictors of stability in DLS: restabilization signs (disc height loss, osteophyte formation, vertebral endplate sclerosis, and ligament ossification), no disc angle change or less than 3 mm of translation on dynamic radiographs, and the absence of low-back pain. The validity and magnitude of each parameter’s contribution can only be determined through appropriately powered prospective evaluation in the future. Identifying these parameters has allowed for the creation of a preliminary DLS instability classification (DSIC) scheme based on the preoperative assessment of DLS stability. CONCLUSIONS Spinal stability is an important factor to consider in the evaluation and treatment of patients with DLS. Qualitative assessment of the best available evidence revealed clinical and radiographic parameters for the creation of the DSIC, a decision aid to help surgeons develop a method of preoperative evaluation to better stratify DLS treatment options.

The article presents the analysis of breeding work with garden roses, carried out in the Nikitsky Botanical Gardens (NBG) from 1824 to the present time. There are three main historical stages, which have different breeding tasks, as well as methods of work: the first stage is connected with the work of N.A. Hartwiss, the second stage – N.D. Kostetsky and the third one – V.N. Klimenko, Z.K. Klimenko and K.I. Zykov. The most significant breeding achievements of the NBG’s rose breeders are indicated. Based on the analysis of the results of the introduction study of garden roses in the NBG, the main features of garden roses cultivation in the Southern Coast of the Crimea (SCC) are specified and the requirements for cultivars created for these conditions are determined. It is established that currently in the breeding work with roses in the NBG, there are four main directions. The first direction is the creation of cultivars with multiple long flowering, the total duration of which can exceed 200 days. A cultivar must endure difficult xerothermic conditions of the Southern Coast in July – August without losing of decorative value. The second task is the selection work with garden groups that are difficult to cultivate in the more northern areas. Among them, under conditions of the SCC, there are highly promising garden groups of miniature and climbing roses. The third direction of breeding is to increase resistance to major fungal diseases affecting roses under the conditions of the SCC. The basic breeding methods to achieve this objective are given. The fourth research line is the creation of cultivars with a strong aroma. These cultivars can be used in aerophytotherapeutic rosaries, arrangement of which in the SCC is relevant in connection with the development of the resort industry.
