Borax is a chemical substance that is prohibited from being used as a food additive because of its toxic nature. However, the use of borax is still widely found, one of which is meatballs the most. This study aims to identify the borax content in meatballs. Samples were taken from Ciroyom Market, Bandung City, Indonesia using total sampling and obtained as many as 10 samples of meatballs. The samples were analyzed qualitatively by observing physical conditions and testing using BaCl2 solution. Meanwhile, quantitative analysis was carried out using a UV-Vis spectrophotometer at a wavelength of 428 nm. The results of the analysis showed that all samples were indicated to contain borax. Even the quantitative test using UV-Vis spectrophotometer showed that the highest borax content was found in sample 10, which was 3.672,9 µg/ml.

Aims: Perform a qualiquantitative analysis of adult arboreal individuals in urban roads in the municipality of Várzea, Paraíba, Brazil. Study Design: Census inventory. Place and Duration of Study: Várzea Municipality, Paraíba, Brazil from March to April 2018. Methodology: The qualitative and quantitative census inventory of adult shrubs-tree individuals was carried out in the urban roads of the municipality, the level of inclusion of the individuals was circumference at breast height (CBH) of (1.30 m) was ≥ 6 cm. Common name of the species was recorded, CBH measurements, height of the first bifurcation and total and physical conditions that were classified as good, regular, bad and dead. The data were tabulated, processed and presented in tables and graphs. Results: A total of 429 individuals were recorded on public roads distributed in 20 species. Azadirachta indica A. Juss and Ficus benjamina L. had the highest number of individuals. 85% of the species were exotic and 15% were native. 12 species offered direct nutritional benefit to man and local fauna as they were fruit trees. The physical conditions of the individuals were 55.94% good, 40.33% regular, 3.73% poor, however, 47.50% of individuals had some type of conflict. 41.72% of individuals were concentrated in the diametric class of 15-21 cm. 54.78% of individuals had height of the first bifurcation greater than 200 cm and 62% of the individuals medium size. Conclusion: The afforestation of the municipality was satisfactory in relation to plant health. Attention needs to be paid to the diversity of native species and the injuries caused to vegetation. The height of the first fork was adequate. The trees were medium sized. It is suggested that studies of perception of afforestation be carried out in the municipality.

Positive Effect

This chapter presents a quantitative test of the theory that extensive diplomatic embeddedness between pivotal states and third parties is likely to increase the likelihood of coalition contributions. The results of the quantitative analysis reveal that diplomatic embeddedness matters greatly. Diplomatic embeddedness is, however, not the only factor influencing troop deployments. When it comes to U.S.-led coalitions, some proxy variables for the preference convergence theory matter equally, although, arguably less consistently than diplomatic embeddedness. The same is true for multilateral coalitions. Here, being located in the region of operation has a strong and consistently positive effect on the probability of deploying forces. In addition, democracies are more likely to join such multilateral coalitions. Moreover, simultaneous deployments increase the likelihood of coalition participation. This indicates that a particular set of countries has a special penchant to deploy military forces abroad, even simultaneously in different theaters.

Quantitative Test

This study aims to test and prove the presence of borax and formalin contamination in shumai samples sold in Palu City. A qualitative method with curcumin paper test; and quantitatively using the UV-Vis spectrophotometer method on a 550 nm wavelength, so that the borax content can be determined in the sample. From the results of this study as many as 5 shumai samples examined, all samples from 5 samples tested qualitatively positive were found before the quantitative analysis was carried out before the samples were tested qualitatively. Qualitative tests showed that some samples did not contain formaldehyde but positively contained borax so the quantitative test was only conducted to determine borax levels in shumai. The results stated that the lowest level was 0.0213 mg/g and the highest level was 0.0314 mg/g.

Photodissociation Region

Aims. Messier 8 (M8) is one of the brightest HII regions in the sky. We collected an extensive dataset comprising multiple sub- millimeter spectral lines from neutral and ionized carbon and from CO. Based on this dataset, we aim to understand the morphology of M8 and that of its associated photodissociation region (PDR) and to carry out a quantitative analysis of the physical conditions of these regions such as kinetic temperatures and volume densities. Methods. We used the Stratospheric Observatory For Infrared Astronomy (SOFIA), the Atacama Pathfinder Experiment (APEX) 12 m, and the Institut de Radioastronomie Millimétrique (IRAM) 30 m telescopes to perform a comprehensive imaging survey of the emission from the fine structure lines of [C II] and [C I] and multiple rotational transitions of carbon monoxide (CO) isotopologs within 1.3 × 1.3 pc around the dominant Herschel 36 (Her 36) system, which is composed of at least three massive stars. To further explore the morphology of the region, we compared archival infrared, optical, and radio images of the nebula with our newly obtained fine structure line and CO data, and in particular with the velocity information these data provide. We performed a quantitative analysis, using both LTE and non-LTE methods to determine the abundances of some of the observed species, kinetic temperatures, and volume densities. Results. Bright CO, [C II] and [C I] emission have been found toward the HII region and the PDR in M8. Our analysis places the bulk of the molecular material in the background of the nebulosity illuminated by the bright stellar systems Her 36 and 9 Sagitarii. Since the emission from all observed atomic and molecular tracers peaks at or close to the position of Her 36, we conclude that the star is still physically close to its natal dense cloud core and heats it. A veil of warm gas moves away from Her 36 toward the Sun and its associated dust contributes to the foreground extinction in the region. One of the most prominent star forming regions in M8, the Hourglass Nebula, is particularly bright due to cracks in this veil close to Her 36. We obtain H2 densities ranging from ~104–106 cm–3 and kinetic temperatures of 100–150 K in the bright PDR caused by Her 36 using radiative transfer modeling of various transitions of CO isotopologs.

Following the well-known physical theory of recombination and forbidden-line emission, we have carried out calculations which may be useful for a quantitative analysis of the observations of planetary nebulae and other emission objects (diffuse nebulae, emission details in extragalactic nebulae, symbiotic and flare stars). As the result, we have a set of four types of graphs.

Dynamic Phenomena

It is well-known that solar activity is basically caused by the Interaction of magnetic fields with convection and solar rotation, resulting in a great variety of dynamic phenomena, like flares, surges, sunspots, prominences, etc. Many conferences have been devoted to solar activity, including the role of magnetic fields. Similar attention has not been paid to the role of magnetic fields for the overall dynamics and energy balance of the solar atmosphere, related to the general problem of chromospheric and coronal heating. To penetrate this problem we have to focus our attention more on the physical conditions in the ‘quiet’ regions than on the conspicuous phenomena in active regions.
