This research aims to analyze the growth rate, and the role of the fisheries sector also to analyze the linkage between the fisheries sector and other sectors in the economic growth rate in the Batubara district. The results of research can be used by local communities and the government as material consideration in determining a policy of management of the economic sector, especially the fisheries sector. This research was carried out from April 2017 to April 2018. The methods utilized are regional superiority analysis, klassentypology analysis, and correlation analysis. The results showed that LQ. LI and SI values of the fisheries sector of Batubara District tend to increase in value from year to year and the fisheries sector itself is in a state of growth. Still, Typology Klassen analysis reveals that the fisheries sector of Batubara district is in the second quadrant. This means that it is advanced but depressed. Moreover, the role of the fisheries sector to other sectors is in the provision of production factors and capital base due to the economy factors built-in to the same space. Herein, the result of correlation analysis of the fisheries sector with other sectors is 0,9. This shows that there is a very strong linkage between the fisheries sector and other sector values in the Batubara District.

Continuing miniaturization of electronic devices necessarily requires assembly of several different objects or devices in a small space. Therefore, besides thin films growth, the possibility of fabricating wires and dots [1, 2] at the nanometre scale composed of metal silicides is of the top interest. This report is about the STM/STS investigation of cobalt silicides’ nanostructures created on Si(111)-(√19 Ã- √19) substrates via Co evaporation and post deposition annealing. This (√19 Ã- √19) reconstruction was induced by Ni doping. Less than 1ML of Co on surface was obtained. Surface reconstruction induced growth of agglomerates of clusters rather than an uniform layer. The post deposition annealing of a crystal sample (up to 670 K, 770 K, 870 K, 970 K, 1070 K and 1170 K) led to creation of silicides’ nanostructures. Measurements showed that coalescence of Co nanoislands begun around 970 K. Annealing above 1070 K led to alloying of a Co, Ni and Si. As a consequence the Si(111)-(7Ã-7) reconstruction occurred at the cost of Si(111)-(√19 Ã- √19).

Purpose. Although the contribution of anaerobic power in soccer performance is recognized, this component of physical fitness is not well-studied in adolescent players. The aim of this study is to investigate the development of anaerobic power across adolescence in a laboratory setting. Methods. Male adolescents (N = 217; aged 12.01-20.98 y), classified into nine one-year age-groups, and adult players (as the control group, N = 29; aged 21.01-31.59 y), who were all members of competitive soccer clubs, performed the 30-s Wingate anaerobic test (WAnT) against a braking force of 0.075 Kg · Kg-1 of body mass. Results. Compared with previous age-matched studies on the general population, the participants exhibited superior WAnT scores. The Pearson moment correlation coefficient between age and peak power (Ppeak) was r = 0.71 (p < 0.001) and between age and mean power (Pmean) r = 0.75 (p < 0.001). Even when body mass or fat free mass was taken into account, the effect of age on these parameters remained (0.51 < r < 0.55, p < 0.001). One-way analysis of variance revealed differences in anaerobic power between the age groups across adolescence (p < 0.001), with the adult and age groups in the higher spectrum of adolescence performing better than those in the lower spectrum, supporting the aforementioned findings. Conclusions. We confirmed the importance of short-term power in adolescent soccer players, as well as the strong association between this sport-related physical fitness parameter and body mass and fat free mass (0.89 < r < 0.94, p < 0.001). However, what is novel is that we demonstrated that age effect on Ppeak and Pmean remained even when body mass and fat free mass were factored out.

Many factors in the natural, man-made and social environments can influence the physical growth and maturation and behavioral development of children and adolescents. Improved environmental conditions over the past century or so have contributed to positive secular changes in growth and maturation. More recently, however, technological advances have increased opportunities for sedentary behaviors and contributed to reductions in physical activity, both of which have potentially negative implications for the health of youth. Pollutants associa-ted with some industries also have implications for health. Children with elevated lead levels are at increased risk for impaired growth and maturation and for impairments in fine motor coordination. The impact of elevated lead on gross motor coordination in several tests of physical fitness is mediated through the influence of lead on growth in body size. Similarly, emissions from coal-fired power plants and other industries are associated with asthma, which has implications for the physical activity and fitness of youth.

Wiele czynników środowiskowych naturalnych, wytworzonych przez człowieka oraz społecznych może wpływać na na rozwój fizyczny, dojrzewanie i rozwój behawioralny, tj. zachowania się dzieci i młodzieży. Polepszenie warunków środowiskowych w ostatnim stuleciu przyczyniło się do pozytywnych sekularnych zmian we wzroście i dojrzewaniu. Ostatnio jednak postęp technologiczny wzmógł łatwość zachowań sedentarnych i przyczynił się do zmniejszenia aktywności fizycznej, co potencjalnie niesie negatywne skutki dla zdrowia młodzieży. Zanieczyszczenia przemysłowe mają również wpływ na zdrowie. Dzieci z podwyższonym poziomem ołowiu w krwi mają podwyższone ryzyko zaburzenia wzrostu i dojrzewania, a także uszkodzenia koordynacji motorycznej. Wpływ podwyższonego poziomu ołowiu we krwi na powstawanie zaburzeń motorycznych jest badany za pomocą wielu testów sprawności fizycznej, jest wyrażony przez wpływ ołowiu na wzrost i wielkość ciała. Podobnie emisje zanieczyszczeń z elektrowni węglowych i innych zakładów przemysłowych są związane z astmą, co ma również wpływ na aktywność fizyczną i sprawność młodzieży.

Polycrystalline diamond films with preferred (111) and (222) facets were fabricated inside hot filament chemical vapour deposition reactor on silicon wafers using a mixture of 1% methane in hydrogen at various reactor pressures ranging from 10 to 50 mbar. Regarding characterization of diamond films, internal texture, surface morphology, quality of diamond and electrical conductivity were investigated using X-ray diffraction, scanning electron microscopy, the Raman spectroscopy and four-point-probe van der Pauw techniques, respectively. Results of these studies demonstrate that polycrystalline diamond structure is grown in random orientation with (111) facet being dominant showing sharp grain boundaries. Moreover, growth rate was found to increase with pressure up to 20 mbar and then decreased for further rise in pressure. That is why grain density is high with relatively smaller grains at higher pressures caused by higher nucleation rates. In contrast, electrical resistivity decreased ≈3 orders of magnitude showing a minimum at 2.9×10⁶ Ω cm as pressure was increased in the reactor. Reactor pressure during film growth resulted in poor surface morphology, absence of sp³ bonds and low resistivity. Hence, decrease of resistivity makes diamond films desirable for many electrical applications in semiconducting/electronic devices.

This research aims to investigate the effect of adding potassium diformate to commercial feed on the increase of absolute growth rate and the activity of protease enzyme. The research was conducted from July to October 2019 in the Aquaculture Laboratory Faculty of Fisheries and Marine Sciences, Padjadjaran University. The method applied in this research was an experimental method using a Completely Randomized Design (CRD), which consists of four treatments and four replications. The treatments were: (A) without addition of Potassium diformate (control), (B) addition of Potassium diformate by 0.3%, (C) addition of Potassium diformate by 0.5%, and (D) addition Potassium diformate by 0.8%. The test fish were 300 giant gouramis with 4-6 cm in length. The containers used in this research were 16 rearing aquaria with a size of 40  30  40 cm3. The density of studied giant gourami fingerlings was 10 fish per aquarium. The rearing period was 40 days. The feeding rate was 3% from biomass. Water quality parameters (temperature, pH, and dissolved oxygen), the absolute growth rate, feed conversation ratio and survival rate were observed every 10 days. The protease enzyme activities were observed at the end of the research. Data on the absolute growth rate, feeding conversion ratio, the characteristics of protease enzyme and survival rate were analyzed using the Analysis of Variance (ANNOVA) continued with Duncan’s Multiple Range Test at the level of 95%, while the water quality was analyzed descriptively. The results show that the addition of potassium diformate by 0.3% gave the best result with the absolute growth rate of 1.50%, feed conversion ratio of 2.70, protease enzyme activity by 634.2 μ/mL and survival rate of 100%.

Haematology is used in assessing the health status of man and livestock. A 10-week feeding experiment was conducted to evaluate the haematological profile of Clarias gariepinus juveniles fed Pueraria phaseoloides leaf meal (PLM) inclusion diets. Five isonitrogenous diets (D1-D5) were formulated to contain 40% crude protein with inclusion of PLM at 0%, 5%, 10%, 15% and 20% levels, respectively. D1 (0% PLM) served as the control diet. One hundred and fifty C. gariepinus juveniles of initial mean weight of 79.87 ± 5.85 g were randomly allocated to five dietary groups (G1-G5) and three replicates each and fed with the five PLM formulated diets, respectively, at 5% biomass daily. Fifteen concrete tanks of 1m3 volume each were used for the experiment. Each tank was stocked with 10 juveniles. Results showed improved blood profile of fish in all the treatment groups as the inclusion levels of PLM in the formulated diets increased up to the 20% level. The present findings showed that PLM inclusion diets enhanced the blood profile of the experimental fish, hence can be used to ameliorate anemic conditions in African catfish.

Introduction: As the most important period in the formation of the feet is considered to be preschool and early school age. The aim of the study was to evaluate the development of the feet in children of preschool age taking into account age and gender. An additional aim was to determine whether using simple testing methods available for physiotherapists can reliably determine the parameters of the foot in children. Material and methods: The study was conducted among 95 preschool children 49 girls (51.6%) and 46 boys (48.4%). The following data were analyzed: sex, age, anthropometric data. The research was conducted by foot print method. Following parameters were analyzed: length and width of the foot, ALPHA - hallux valgus angle, BETA - the little finger varus angle, GAMMA - heel angle, the Wejsflog index and Clarke index. Results: The study using the footprint method allowed an accurate assessment of the foot of the study group. Highly statistically significant relationship between the width and length of the right and left foot, and the age of the children was confirmed. In the case of Wejsflog index highly significant differences between the measurements in children 5-year-old children in comparing to children 3-year-old and 4-year-old were reported. There were no differences between the structure of children’s feet, taking into account their sex. Conclusion: 1. Structure of girls and boys foot during their progressive development did not significantly differed, suggesting the absence of a clearly marked sex dimorphism in the development of the foot arch. 2. Most of the children foot had proper structure, thus ordering corrective exercises for all children migth not be reasonable. 3.The study confirmed the high value of footprint method.

Planting mangroves on Pramuka Island is done in a monoculture way and usually fails. However, the planting managed by the Kepulauan Seribu National Park has become more successful. The specific objective of the research was to quantify the success rate of mangrove planting in Pramuka Island based on survival, growth and benthos levels in Pramuka Island mangroves. The mangrove planting area that was used as the research sample was an area wherein the planting are 14, 12 and 6 years old. The type of mangrove that planted is Rhizophora stylosa. The number of plots was determined based on the area. Data was collected in the form of primary data, namely, the number of living trees, tree heights, number of leaves and leaf dimensions. The success of mangrove planting reached 52%, 66.43% and 57.5% at stations 1, 2 and 3. The highest success rate was at station 2, while stations 1 and 3 are considered failures. This indicates that Pramuka Island has a low success rate of mangrove planting.

The main threats to human health from heavy metals are associated with exposure to lead, cadmium, mercury and arsenic. These metals have been extensively studied and their effects on human health regularly reviewed by international bodies such as the WHO. Heavy metals have been used by humans for thousands of years. Although several adverse health effects of heavy metals have been known for a long time, exposure to heavy metals continues, and is even increasing in some parts of the world, in particular, in less developed countries. However, over the last 100 years, emissions have declined in most developed countries. Cadmium compounds, the exception, are currently mainly used in re-chargeable nickel-cadmium batteries. Cadmium emissions have increased dramatically during the 20th century, one reason being that cadmium-containing products are rarely re-cycled, but often dumped together with household waste. Cigarette smoking is a major source of cadmium exposure. In non-smokers, food is the most important source of cadmium exposure. Recent data indicate that adverse health effects of cadmium exposure may occur at lower exposure levels than previously anticipated, primarily in the form of kidney damage, but possibly also in bone effects and fractures. Many individuals in Europe already exceed the recommended exposure levels and the margin is very narrow for large groups. Therefore, measures should be taken to reduce cadmium exposure in the general population in order to minimize the risk of adverse health effects. The general population is primarily exposed to mercury via food, fish being a major source of methyl mercury exposure, as is dental amalgam. The general population, however, does not face a significant health risk from methyl mercury, although certain groups with high fish consumption may attain blood levels associated with a low risk of neurological damage to adults. Since there is a risk to the fetus in particular, pregnant women should avoid a high intake of certain fish, such as shark, swordfish and tuna; fish (such as pike, walleye and bass) taken from polluted fresh waters should especially be avoided. There has been a debate on the safety of dental amalgams and claims have been made that mercury from amalgam may cause a variety of diseases. However, there are no studies so far that have been able to show any associations between amalgam fillings and ill health. The general population is exposed to lead from air and food in roughly equal proportions. During the last century, lead emissions to ambient air caused considerable pollution, mainly due to lead emissions from petrol. Children are particularly susceptible to lead exposure due to high gastrointestinal uptake and the permeable blood-brain barrier. Blood levels in children should be reduced below the levels so far considered acceptable as recent data indicates that lead may hold neurotoxic effects at lower levels of exposure than previously anticipated. Although lead in petrol has dramatically decreased over the last decades, thereby reducing environmental exposure, phasing out any remaining uses of lead additives in motor fuels should be encouraged. The use of lead-based paints should also be abandoned, and lead should not be used in food containers. In particular, the public should be aware of glazed food containers, which may leach lead into food. Exposure to arsenic is mainly via intake of food and drinking water, food being the most important source in most populations. Long-term exposure to arsenic in drinking water is mainly related to increased risks of skin cancer, but also enhanced risk of some other cancers, as well as other skin lesions such as hyperkeratosis and pigmentation changes. Occupational exposure to arsenic, primarily by inhalation, is causally associated with lung cancer. Clear exposure-response relationships and high risks have been observed.
