ABSTRACTCzochralski technique was employed in an attempt to grow a single crystal of the system ZnO-TeO2. A good quality grown crystal is expected to be transparent with a very light yellow color. The crystals exhibit a high resistivity of the order of 1013 Ω-cm. Different mole percentages have been tested for growth. Several attempts were performed to pull a single crystal. It was found that the best mole percentage of ZnO-TeO2 is 35.5:64.5. The pulled material grows uniformly, such that necking and conning are noticed. The pulled material contained multiple single crystals which were isolated and studied. Each one of them was transparent. Some properties will be presented. The pulled material of the 40:60 ZnO-TeO2 mole percentage returned four phases. Two of these phases are very uncommon.

The article presents the results of research on bactericidal properties of the new domestic disinfectant «GK-10», which is a transparent solution of light yellow color, without mechanical inclusions with a specific odor. It is well mixed with water. It is based on alkyl dimethylbenzyl ammonium chloride (QAC) and dodecylbispropylentriamine (1,3-prodadiene) (tertiary amines). Was found bactericidal dilution (BD), bactericidal concentration (BC), phenolic coefficient (FC) and protein index (PI). Thus, the most susceptible to the action of the disinfectant were were gram-negative bacteria E. coli, where cell death occurred at 10 and 30 minute exposures at concentrations of 0.19 and 0.14%, respectively. Due to the action of the disinfectant on the gram-positive bacteria S. aureus, cell death came at these exposures at concentrations 0.27 and 0.19%, respectively. The least susceptible to the action of the disinfectant were vegetative forms of B. subtilis, the death of these bacteria came at concentrations 0.37 and 0.27% at 10 and 30 minutes of exposure, respectively. Effects of disinfectant was over 5.38 and 2.74 times higher on microorganisms of E. coli and S. aureus, respectively, of the decontamination effect of phenol, and in the presence of protein, the activity of the disinfectant is reduced by 6.45 times. The efficiency of the disinfectant for the strains of microorganisms at the disinfestation of the test-object surfaces is determined. It has been established that for test cultures of E. coli and S. aureus 0.05–0.3% of disinfectant concentration is ineffective, and 0.5% its disinfectant concentration for disinfection of hard surfaces in preventive disinfection of premises for animals is insufficient for exposure in 120 minutes. For spore form B. subtilis 1.0% disinfectant concentration was ineffective. 1.0% concentration is effective for aseptic cleaning: slaughterhouses, processing shops, laboratory facilities, means of transporting products of animal origin, soaking clothes before washing, and also for treating surfaces of wood, metal and glazed tile at exposures of 60 minutes and more, and when spore forms of microorganisms, the working concentration of insoluble in disinfection of objects subject to veterinary control should be 3% and above. It has been proved that the disinfectant «GK-10» is effective at a concentration of 0.5% at exposure for 180 minutes and at a concentration of 1.0% at an exposure of 120 minutes for the sanation and preventive disinfection of premises for animals.

Instant Noodles

Instant noodles originated in eastern nations and have been accepted due to its practicality and low cost. However, its high sodium content can lead to health problems. The present study aimed to reduce sodium and increase calcium levels in noodles. A control (N1: K2CO3+ Na2CO3) and three treatments with the addition of calcium carbonate in combination with alkaline salts such as potassium and sodium carbonates (N2: K2CO3+ CaCO3; N3: Na2CO3+ CaCO3; and N4: CaCO3) were studied. Two hydration methods were investigated, and the technological characterization and the calcium bioaccessibility of the different noodle formulations were determined. N4 did not fit into the alkaline noodle category due to its neutral pH.  N2 and N4 showed a sodium reduction of around 28% and a significant increase in calcium content, with higher bioaccessible calcium. Significant changes were observed for the noodles made with the addition of different alkaline salts, with a light-yellow color and better texture than the control, which can be a positive aspect, once products with reduced nutrients usually present differentiated coloring. Therefore, the use of calcium carbonate may be a promising alternative to increase Ca intake and to reduce the sodium content of instant noodles.

Young people often experiment with alcohol during adolescence, which is a period of their life that is characterized by increasing responsibility. Knowing how adolescents perceive responsibilities with regard to their alcohol use could prevent their alcohol consumption and help them to take responsibility for this aspect of their lives. This study describes adolescents’ perceptions and experiences of their responsibilities for alcohol use. We used a qualitative descriptive method that focused on 87 adolescents aged 14–16 years, from two schools. They took part in semi-structured interviews in 19 groups in Finland in 2017. The data were analyzed using inductive content analysis. The adolescents described alcohol as harmful, but tempting, and said that they were developing a sense of responsibility for their alcohol use. They were responsible for their own wellbeing, behaving responsibly if they drank and intervening in peers’ alcohol use. They talked about how their parents had unquestionable responsibilities to care about whether adolescents drank alcohol. Their parents’ responsibilities related to the guidance they gave, how strict they were and how they responded to adolescents using alcohol. Anonymous and intense support from authorities encouraged adolescents to learn to take responsibility. Identifying and focusing on their responsibilities could help adolescents to develop into healthy individuals and increase their awareness of the need to avoid alcohol. Parents may also need support to meet their responsibilities.

<p>El Picudo, <em>Conotrachelus psidii </em>Marshall, desarrolla su estado larvario en el fruto de la guayaba alimentándose de la semilla; el insecto petrifica y madura prematuramente la fruta confiriéndole un aspecto desagradable que causa rechazo en el mercado. En la actualidad causa pérdidas significativas en la agroindustria de la Hoya de Río Suárez. Conocer la duración de los estadios biológicos y sus preferencias de oviposición, permitirá diseñar estrategias de manejo integrado. Los huevos y las larvas se obtuvieron semanalmente de frutos infestados artificialmente para conocer los cambios morfológicos de la cabeza de la larva y la duración del estadio. Cuando las larvas abandonaron el fruto se introdujeron en dispositivos plásticos tubulares saturados con tierra, los cuales se disectaron mensualmente para registrar los estadios de larva, pupa y adulto en el suelo. Se observó que las hembras ovipositaron frutos de 30 a 90 días de edad; los huevos son blanquecinos y con longitud promedio de 1 mm. La larva es ápoda y de color amarillo, con longitudes entre 1,2 y 1,5 mm y entre 10 y 12 mm en las semanas primera y sexta, respectivamente. La pupa es exarata, amarilla clara y de 7,5 mm de longitud. El adulto es café oscuro y tiene 6 mm de largo. El ciclo total duró 199 días distribuido así: huevo, 4 a 7 días; larva en el fruto, 42 a 56 días; larva en suelo, 90 días; pupa, 30 a 60 días. Los adultos emergieron entre 20 y 30 días en la época lluviosa y en laboratorio sobrevivieron hasta 435 días después de su emergencia.</p><p> </p><p><strong>Biology of the guaba weevil <em>Conotrachelus psidii </em>(Marshall) (Coleoptera: Curculionidae)</strong></p><p>The weevil <em>Conotrachelus psidii </em>(Marshall) develops its larval stages inside the guava fruit feeding on its seeds, and petrifying and prematurely ripening the fruit, developing an unpleasant appearance, rejected by the market.

In recent decades the interest to the study of Hedysarum has increased. Researchers touched upon the classical issues of morphology and variability of external features of Hedysarum grandiflorum and other species of Hedysarum (to clarify morphology, to more accurately separate existing species, to describe the morphology of new species, including rare ones) providing almost no detailed descriptions. The paper provides information about the morphology of external features of H. grandiflorum in the Southern Volga Upland. The study was conducted in 2007–2018. We have studied 23 H. grandiflorum cenopopulations in habitats with various environmental conditions, where more than 600 counting sites were laid, and concluded that the morphological features of H. grandiflorum are rather variable and the values of morphometric parameters are higher in the northeastern part of the study area. The well-being of the population is achieved due to some heterogeneity in the size of individual plants and by means of suppressing the growth and size of separate cenopopulations. The decrease in the parameters of signs is often associated with a higher anthropogenic load. Dimensional indicators of individuals from the cenopopulations of the species studied depend on the thickness of soil, which decreases from fescue-feather grass to petrophyte steppes. Cluster analysis has allowed us to divide the cenopopulations into southern, northern and northeastern ones, and those with anthropogenic impact. The least variable and most informative morphological features of H. grandiflorum (in the descending order of importance) are: the length of the standard, the diameter of the caudex, the plant height, the number of foliole pairs, the number of inflorescences, the number of leaves, the length of the unpaired foliole, the number of flowers on the inflorescence, the length of leaves and the width of the unpaired foliole. In the overwhelming majority of the plants encountered, all the petals of the corolla were of uniform light yellow color, turning into a white tint to the edges of the petals. In some cenopopulations, the corolla can be colored differently and unevenly, especially at the keel. Approximately 0.3% of individuals of the corolla petals and/or the lower part of the keel and/or veins are light blue or light pink, less than 0.07% has a light magenta or even light purple tint of the veins of the carina, edges of the petals or the whole corolla. Similar individuals are found in other regions. Many scientists noted this peculiarity a long time ago and had already described this phenomenon as a color variation (for example, H. grandiflorum var. violaceum) or less often, as a subspecies (for example, H. grandiflorum ssp. argenteum). Individuals with recessive coloring of the corolla from the area of study are called intraspecific color variations.

Carotenoids are important coloration molecules and indispensable component of the human diet. And these compounds confer most of the apricot fruit yellow or orange color. In China, fruit of some apricot cultivar present light-yellow color but strong flowery flavor, however, the chemical mechanism remains unknown. Here, carotenoids and aroma volatile apocarotenoids (AVAs) in three skin types of apricot cultivars (orange, yellow, and light-yellow skinned) were determined by HPLC and GC-MS, respectively. And the transcript levels of carotenogenic genes were analyzed by qRT-PCR. The orange-skinned cultivars “Hongyu” and “Danxing” fruit presented the most abundant total carotenoid, β-carotene and specific α-carotene contents, and β-carotene (52–77%) increased to become the dominant carotenoid during fruit ripening. The transcript levels of lycopene β-cyclase (LCYb) and β-carotene hydroxylase (CHYb) sharply increased during ripening. The yellow-skinned cultivars “Sulian No. 2” and “Akeyaleke” fruit contained lower levels of total carotenoids and β-carotene but were rich in phytoene. The light-yellow coloration of “Baixing” and “Luntaixiaobaixing” fruit was attributed to low amounts of total carotenoids, lutein, and neoxanthin and an absence of β-cryptoxanthin, but high level of aroma volatile apocarotenoids (AVAs) such as β-ionone were detected in these cultivars fruit, accompanied by low transcript levels of carotene hydroxylase (CYP) and zeaxanthin epoxidase (ZEP) but high levels of carotenoid cleavage dioxygenase 1 (CCD1) and CCD4. Correlation analysis showed that the expression level of CCD1 negatively correlated with carotenoid accumulation but positively with AVAs production. These collected results suggest that both carotenoid biosynthesis and degradation are important for apricot coloration and aroma formation. CYP, ZEP, CCD1, and CCD4 may be the key regulation points for carotenoid and AVAs accumulation in apricot fruit, which provide important targets for quality-oriented molecular breeding.
