The results of laboratory and production tests of the effectiveness of the disinfectant Palocid for the disinfection of objects of veterinary supervision are presented. As test microorganisms were used the museum cultures of E. coli (strain 1257), Staphylococcus aureus (strain 209-P), bacilli (strain B5), B. cereus (strain 96). Inactivated blood serum of the horse was used to simulate natural contamination of surfaces. The quality of the disinfection was controlled by examining the washings from the test and control test objects for the presence of a given test culture. The results of laboratory and industrial tests show that Palocid is an effective disinfectant and can be recommended for preventive and forced disinfection in livestock, poultry, fur farming, automobile and railway transport, while monitoring its quality in the isolation of bacteria of the E. coli and staphylococcus group, as well as forced disinfection at the objects of veterinary supervision for infectious diseases of bacterial (including tuberculosis) and viral etiology, especially dangerous infections (anthrax and other spore infections).

Authors:   Russian Research Institute of Radiology and Agroecology, Obninsk, Kaluga region, Russian Federation, Mirzoev E. B.
Published: July 2021

Based on the literature and experimental data, the most informative biomarkers of lead exposure in chronic intake with diet in the organism of the sheep. The choice of biomarkers of exposure was based on the mechanism of action of lead and the regularities of income distribution, accumulation and elimination from the orgsnism, as well as the specificity, sensitivity and informative value of laboratory parameters. Comparative analysis of biomarkers of effect of lead on the criteria of specificity, sensitivity, information content and complexity allows to highlight the following several laboratory parameters: the activity of δ-ALAD in peripheral blood > the contents of metallothioneins in peripheral blood lymphocytes > the content of SH groups in plasma of peripheral blood. Of the above biomarkers of effect are reversible, which reduces their information content. At the same time of biomarkers of exposure considered priority lead concentrations in the peripheral blood. Scientific justification for critical limits of lead exposure for mammals is focused on the estimation of the dependence of the biological effects from its concentration in the peripheral blood. Therefore, the most informative biomarkers of exposure are the activity of δ-ALAD and the concentration of the metal in the peripheral blood.
ИЗУЧЕНИЕ РЕАКЦИИ ИЗОМЕРИЗАЦИИ БУТЕНА-1 В БУТЕНЫ-2 НА БИНАРНЫХ МЕДЬ СОДЕРЖАЩИХ КАТАЛИЗАТОРАХ.
Authors: Салима Мамедова Салима Мамедова
Published: July 2021

С целью оценки кислотно-основных свойств поверхности бинарных медь содержащих катализаторов изучены их активности в реакции изомеризации бутена-1 в бутен-2. Реакцию изомеризации бутена-1 в цис и транс бутены-2 проводили на проточной установке с трубчатым реактором в интервале температур 100-400°С. Установлено, что скорость изомеризация бутена-1 на медь содержащих катализаторах зависит как от температуры реакции дегидрирования, так и от природы второго металла в составе бинарного катализатора. Так активность бинарных медь содержащих катализаторов в реакции изомеризации бутена-1 в бутены-2 располагается в следующий ряд: Cr-Cu-O > Zn-Cu-O > Ce-Cu-O. Показано, что при низких температурах увеличение содержания второго оксида в составе бинарного медь содержащего катализатора приводит к снижению скорости реакции изомеризации бутена1 в транс и цис бутены-2. Однако при высоких температурах для каталитической системы Zn-Cu-O с увеличением содержания цинка скорость изомеризации бутена-1 проходит через максимум, в то время как для каталитической системы Ce-Cu-O скорость изомеризации бутена-1 проходит через минимум. Установлено, что отношение транс-бутена-2 к цис-бутену-2 зависит от типа каталитической системы. Так отношение транс-бутена-2 к цис-бутену-2 для каталитической системы Cr-Cu-О изменяется в пределах 0,31-0,48, для каталитической системы Zn-Cu-O изменяется в пределах от 0,33 до 0,72 и для каталитической системы Cе-Cu-О изменяется в пределах от 0,16 до 0,59.

Published: July 2021

The article discusses the bactericidal effect of compositions of alkylimidazole and oxyethylated para-nonylphenol in various proportions obtained by the interaction of polyethylenepolyamine in a nitrogen medium with various concentrations against sulfate-reducing bacteria.
Alkylimidazole was obtained on a pilot plant with a capacity of 500 kg/day, built at the research and production enterprise "Tural 110" in Sumgait. Alkylimidazole (AIM) is derived from the interaction of natural petroleum acid (NPA) with polyethylene polyamine (PEPA).
The effect of ONP and AIM compositions prepared in mass ratios of 95:5; 90:10 and 50:50 on the incubation period of SRB for 15 days was studied as follows. Reagent-free and reagent media were used for comparison. 1 ml of the bacterial medium was diluted with sterile water and simultaneously transplanted into a Posgate B nutrient medium in 10 ml test tubes in a 1:9 ratio and kept in a thermostat at 30-35°C for 15 days to determine the number of bacteria growing in the medium. As a result, the number of bacteria in the non-inhibitory medium taken under microscopic control was n=108 the number of cells/ml and in the inhibitory medium at a concentration of 50 mg/l in all three samples (AIM:ONP = 5:95; 10:90 and 50:50 in mass ratios) the number was defined as n=101 cells/ml and at a concentration of 250 mg/l AIM:ONP = 10:90 and AIM:ONP = 50:50, the mass ratios fell from 108 to 0, which completely stopped the life of bacteria.

Published: July 2021

Ptilostemon echinocephalus (Willd.) Greuter (Lamyra echinocephala (Willd.) Tamamsch.) is the only species of the genus Ptilostemon from the Asteraceae family that grows on the Crimean Peninsula.
The relic area of Ptilostemon echinocephalus distributed by the Crimea, the Caucasus, Asia Minor. The species is included in the Red Book of the Republic of Crimea, Krasnodarskiy and Stavropolskiy Krays of the Russian Federation. The article is the result of a long-term study of morphological criteria of Ptilostemon echinocephalus age status. Thus, the ontogenesis of individuals of the species Ptilostemon echinocephalus includes 12 age states, the total during of ontogenesis lasts 15–18 years.
The main characters of the pregenerative period differentiation of development are the number of leaves and the differentiation degree of the leaves lamina. During the study, another important feature was identified to indicate different age stages, the ratio of vegetating and dried leaves.
Generative plants were subdivided into: immature generative (g1), adult (mature) generative (g2) and old generative (g3). For the generative stage of development, the ratio of generative and vegetative rosettes, the ratio of dried and vegetative shoots, and the number of baskets were indicative.
Differentiation of subsenile and senile age states is conducted according to the same criteria that are used for generative individuals, the main emphasis is on the ratio of dried and vegetative parts.The article also notes the specificity of the course of ontogenesis depending on the ecological-cоenotic conditions in the petrophytic steppes and phrygana communities of the Crimea.

The diagenetic history of siderite concretions in Mesozoic sedimentary rocks on the island
of Bornholm has been investigated using stable isotope-, AAS- and XRD-analysis and
determination of carbonate content. Siderite concretions and bands, found in non-marine
as well as marine environments, are investigated. The siderite concretions were precipitated
from fresh to brackish pore-water prior to compaction.
8'3CPDB values from -14.2 to +1.4 o/oo indicate ne ar-surface precipitation affected by
bacterial oxidation of organic matter. 8180 values between +22.1 and +28.7 o/oo 5180SMOW
indicate concretion precipitation in pore-water of fresh to brackish origin. Weathering
effects are seen, but temperature fractionation is not observed.
Distribution and intensity of glaciotectonic deformation in
Denmark
Authors: Jakobsen Peter Roll
Published: July 2021

Glaciotectonic deformation has a large impact on the stratigraphical and
lithological variability of Quaternary deposits and the shallow subsurface
pre-Quaternary sediments. Mapping of the distribution of glaciotectonic
deformation involving pre-Quaternary and interglacial deposits has been
carried out, and the density of glaciotectonic deformation analysed, on the
basis of data from the well database ZEUS, at the Geological Survey of
Denmark.
Glaciotectonic deformation is widespread in Denmark. It is recognised
in glacial terrains within morphological well-defined glaciotectonic complexes, and in areas with no obvious glaciotectonic related morphology as
well as in areas covered with postglacial deposits. The dislocated bedrock
is usually not transported for long distances, although rafts of pre-Quaternary bedrock may be transported up to 50 km or more.
On a large scale, regions have been located showing high intensity of
glaciotectonic deformation. Some of these regions are in good agreement
with records from exposures and the geomorphology, others cannot be recognised without well log information.
Seafloor evidence for glaciation, northernmost Baffin Bay
Authors: Blake, Jr. Weston , Jackson H. Ruth , Currie Claudia G.
Published: July 2021

Shaped seafloor features were recorded at three localities on C.S.S. Hudson Cruise
91-039, to northernmost Baffin Bay. They resemble glacially sculptured bedrock
hills, varying from 2.5 to 3.0 km in length, with relief of 70 to >90 m, and they
occur in water depths of 200 to 400 m. These well developed features occur to the
west-southwest, east and north of Carey Øer, an isolated group of islands which
bears strong evidence of having been overridden by glacial ice and on top of
which marine shells in till are >40 000 years old. The sculptured features at each
of the three sites are asymmetric, with well developed stoss and lee sides. Their
shapes and orientations are consistent with the hypothesis of a southward-flowing
Smith Sound Ice Stream expanding into northernmost Baffin Bay. The Smith Sound
Ice Stream is believed to have existed most recently at the Late Wisconsinan glacial maximum, but southward-flowing ice reaching as far as Carey Øer at this
time appears to be at variance with evidence assembled in the Dundas area, Greenland, which suggests a limited advance of ice during the Wolstenholme Fjord
Stade.

Global 21 cm Signal Extraction from Foreground and Instrumental Effects. IV. Accounting for Realistic Instrument Uncertainties and Their Overlap with Foreground and Signal Models

Published: July 2021

All 21 cm signal experiments rely on electronic receivers that affect the data via both multiplicative and additive biases through the receiver’s gain and noise temperature. While experiments attempt to remove these biases, the residuals of their imperfect calibration techniques can still confuse signal extraction algorithms. In this paper, the fourth and final installment of our pipeline series, we present a technique for fitting out receiver effects as efficiently as possible. The fact that the gain and global signal, which are multiplied in the observation equation, must both be modeled implies that the model of the data is nonlinear in its parameters, making numerical sampling the only way to explore the parameter distribution rigorously. However, multi-spectra fits, which are necessary to extract the signal confidently as demonstrated in the third paper of the series, often require large numbers of foreground parameters, increasing the dimension of the posterior distribution that must be explored and therefore causing numerical sampling inefficiencies. Building upon techniques in the second paper of the series, we outline a method to explore the full parameter distribution by numerically sampling a small subset of the parameters and analytically marginalizing over the others. We test this method in simulation using a type I Chebyshev bandpass filter gain model and a fast signal model based on a spline between local extrema. The method works efficiently, converging quickly to the posterior signal parameter distribution. The final signal uncertainties are of the same order as the noise in the data.
Low-frequency Waves Upstream of Quasi-parallel Shocks: Two-dimensional Hybrid Simulations
Authors: Hao Yufei , Lu Quanming , Wu Dejin , Lu San , Xiang Liang , Ke Yangguang
Published: July 2021

In this paper, we study low-frequency waves upstream of quasi-parallel shocks by using two-dimensional (2D) hybrid simulations. Simulation results show that reflected particles can backstream and form a superthermal particle component in plasmas in an area just before the shock front. The component interacts with the incident particles and can result in quasi-parallel and quasi-perpendicular fast magnetosonic waves with comparable wave amplitudes, and they have right-hand and linear polarization, respectively. Further upstream, after being scattered by these upstream waves, the backstreaming particles develop a shell-like velocity distribution so that similar waves can be driven by the free energy from this newly formed distribution, and in this area the quasi-perpendicular waves are dominant over the quasi-parallel ones. Linear theory confirms the generation of these two types of upstream waves.

As this species is restricted to the Chocó forests of the western Andean slope in northern Ecuador, our knowledge is based on a few specimens collected decades ago. Here we add the first data on some aspects of external anatomy (cheiridia examined in fresh, ears, rhinarium), genital anatomy (penis), soft anatomy (palate, stomach, caecum) and postcranial skeleton retrieved from a full adult male, recently trapped in Reserva Drácula, Carchi, Ecuador. Several features of this specimen, paradoxically the first to be added to Ecuadorian mammal collections, reinforce the view that Mindomys is an arboreal sigmodontine.

Comment construire une réflexion sociologique sur les usages des TIC par les lycéens de Terminale ? Certes, on dit d’eux qu’ils font partie de la « génération Google », laquelle suscite des craintes (incompétence documentaire, exposition aux risques d’Internet, etc.). Mais notre posture vise à comprendre leurs usages numériques, notamment ceux liés aux devoirs scolaires, en leur donnant une épaisseur sociale, c’est-à-dire en étudiant les contextes sociaux d’usages et les manières diverses et multiples dont les lycéens parviennent à articuler leur temps de travail scolaire (les devoirs à la maison) et leurs activités extrascolaires (loisirs encadrés à l’extérieur du domicile, loisirs informels et sorties entre copains, pratiques d’informatisation culturelle et de communication électronique).
Comment l’écriture avec le numérique renouvelle la question du sujet adolescent : vers une géographie de l’écriture
Authors: Schneider Elisabeth
Published: July 2021

Le numérique trame la vie des adolescents. De manière indéniable, leurs activités, leur rapport au monde, leurs pratiques culturelles, communicationnelles, et leurs pratiques d’information sont liés aux outils numériques, à des degrés divers. L’écriture reste essentielle dans ces pratiques et permet de poser la question du sujet adolescent parce qu’elle est un outil transversal aux supports, aux lieux, aux activités. L’outillage théorique de l’ethnographie, de la géographie et des Sciences de l’information et de la communication est interrogé en le confrontant aux données issues de l’enquête menée pendant deux ans auprès de lycéens sur Facebook, en classe, en situation de mobilité, à l’internat et à domicile.
La construction du rapport à autrui dans les forums de discussion d’adolescents et ses enjeux en situation d’apprentissage scolaire. Le point de vue de l’analyse des interactions

A travers l’analyse d’un corpus d’interactions en ligne (un échantillon d’échanges prélevés dans le forum de discussion Ados.fr), cet article présente les bénéfices et les limites d’une approche interactionniste pour comprendre le « sujet apprenant numérique ». Avec une telle approche, on parlera d’un « sujet interactant », qui construit sa relation aux autres par et dans les interactions en ligne. Ce point de vue permet de montrer finement la manière dont se construisent des relations complexes (et parfois paradoxales) : à la fois intimes et faiblement interpersonnelles, coopératives et inégalitaires, ludiques et agressives. Cet article propose aussi quelques pistes de réflexion pour analyser les effets des pratiques numériques extrascolaires sur les situations d’apprentissage en ligne.
Le sujet cognitif de l’apprentissage
Authors: Tricot André
Published: July 2021

Les humains qui utilisent des technologies de l’information et de la communication pour l’enseignement (TICE) et pour apprendre réalisent une activité complexe qu’il est difficile d’étudier. Les chercheurs du domaine rencontrent plusieurs problèmes, dont trois sont abordés ici : les apprentissages implicites et explicites, scolaires et non scolaires, avec les TIC peuvent-ils être décrits à l’intérieur d’un même cadre ? Les TICE mobilisent-elles différents processus d’apprentissage ? Qu’est-ce la motivation à utiliser les TIC et cette motivation a-t-elle un effet sur les apprentissages avec les TICE ? Pour répondre à ces problèmes, une approche renouvelée des apprentissages peut aider. Cette approche considère le sujet cognitif de l’apprentissage comme étant capable d’apprendre de manière très différente selon qu’il y a un enjeu adaptatif ou non. Elle considère aussi que le sujet humain mobilise des processus d’apprentissage très différents entre eux, impliquant que les tâches et les outils pouvant soutenir ces processus d’apprentissage sont nécessairement très différents. Enfin, elle considère que les connaissances que le sujet humain a sur lui-même et sur ses buts d’apprentissage ont un effet important.

Highly demand of aesthetic needed made dental composites become a major role as dental restorations. Minimal invasive of sound tissue and the ability to mimic the original teeth also have the recommendation to choose dental composites. The developments of dental composites mostly focus on filler systems to improve mainly in the mechanical and optical properties due to the esthetic aspect of dental care recently has become increasing importance. According to the component of dental composites, the fillers had a big role to determine the properties of dental composite. Many kinds of fillers have been utilized to improve the properties. Two kinds of dental composites had been known based on their fabrication procedure; i.e. experimental and commercial. The experimental dental composites had been produced by the researcher on their formula to obtain good properties while commercial dental composites were made by many manufacturers which have each brand that has each product of excellence, especially in mechanical and optical properties. The aim of this review focused on the mechanical and optical properties of experimental dental composites and commercial dental composites including describes many factors that affect those properties.

Landfill Leachates is one of the pollutants containing high organic matter and heavy metal which can cause toxic pollution to water due to less than optimal leachate processing. This study aims to introduce fine bubbles treatment to the leachate processing technology at the waste treatment facility at Sarimukti, West Java Indonesia. The toxicity test was conducted in the acute toxicity test and test for D. magna. The acute toxicity test was carried out using a static biological test according to APHA standards (1995). The LC50-48 hours ware calculates using the Finney Probit Analysis Software. The results showed that the effectiveness of Sarimukti TPA leachate treatment was 97.5% DO, 71% BOD, 86% TDS, and 74.8% turbidity. The XRF spectra on the leachate after fine bubble found a recovery of heavy metal elements such as Cr, Mn, Fe, Zn, Cu, Pb, As, and Sn. Based on the Minister of Environment and Forestry Regulation, the effectiveness of leachate processing has reached the safe standard limit for pH, mercury, cadmium parameters. The acute toxicity of leachate before and after treatment fine bubble was 14.516 ppm and 11.178 ppm. The acute toxicity of leachate is considered almost non-toxic.

Dissolved oxygen in water is one of the factors affecting plant growth in the hydroponic nutrient film technique system. The fine bubble generator technique allows the provision of high dissolved oxygen levels in water with fine bubble size and prolonged water existence. The experiment was conducted to observe the effect of fine bubbles on choy sum plant growth. Plant growth parameters including leaf length (Pd), leaf width (Ld), plant height (Tt), number of leaves (Jd), and root weight (Ba) were measured every two days while the total plant weight was measured at harvest. Nutritional water quality and microclimate were controlled using internet of things (IoT) based sensors every 5 minutes. The research data were processed using descriptive analysis. The results showed that the use of fine bubbles increased the electrical conductivity (EC), pH, and total dissolved solids (TDS). On the contrary, the nutrient solution’s temperature increased, thus reducing the total dissolved oxygen content. The yields showed that the choy sum plant growth using fine bubbles application weighed 1.71 kg (5 samples) better than the control 1.35 kg.
Suggested Qualification Test Procedure to Secure Splitting Resistance in Pretensioned Concrete Members
Authors: Savić Adrijana , Peterman Robert J. , Beck B. Terry
Published: July 2021

Prestressed concrete ties could develop end-splitting cracks along tendons due to lateral bursting stresses. The lateral bursting stresses can form due to Hoyer effect (change in diameter of the prestressing tendons due to Poisson’s ratio), the jacking force in the tendons, geometrical features and indent characteristics of the prestressing tendons. End-splitting cracks can occur immediately after de-tensioning procedure in some cases, but they also can be developed during the first weeks after de-tensioning procedure due to sustained lateral stresses exerted by the prestressing tendons. The ability of concrete to resist these bursting stresses without cracking is primarily the function of the thickness of concrete cover, the type of concrete mixture used and the maximum compressive strength of the concrete. Qualification test will be great tool for prestressed concrete tie manufacturers to identify tie designs that may be susceptible to end-splitting cracks. This test was formally adopted as section 4.2.4 in Chapter 30 of the 2021 AREMA Manual for Railway Engineering.

As key cells of the immune system, macrophages coordinate the activation and regulation of the immune response. Macrophages present a complex phenotype that can vary from homeostatic, proinflammatory, and profibrotic to anti-inflammatory phenotypes. The factors that drive the differentiation from monocyte to macrophage largely define the resultant phenotype, as has been shown by the differences found in M-CSF– and GM-CSF–derived macrophages. We explored alternative inflammatory mediators that could be used for in vitro differentiation of human monocytes into macrophages. IFN-γ is a potent inflammatory mediator produced by lymphocytes in disease and infections. We used IFN-γ to differentiate human monocytes into macrophages and characterized the cells at a functional and proteomic level. IFN-γ alone was sufficient to generate macrophages (IFN-γ Mϕ) that were phagocytic and responsive to polarization. We demonstrate that IFN-γ Mϕ are potent activators of T lymphocytes that produce IL-17 and IFN-γ. We identified potential markers (GBP-1, IP-10, IL-12p70, and IL-23) of IFN-γ Mϕ and demonstrate that these markers are enriched in the skin of patients with inflamed psoriasis. Collectively, we show that IFN-γ can drive human monocyte to macrophage differentiation, leading to bona fide macrophages with inflammatory characteristics.
