ANALYSIS OF EXPOSURE OF REPRODUCTIVE HEALTH INFORMATION TOWARDS ADOLESCENT SEXUAL BEHAVIOR

range of 10 to 19 years. Adolescents are the population in the age range of 10-18 years. Rapid physical changes and hormonal changes are triggers for sexual motivation. Stimulation from the environment such as TV and the internet about sexual behavior and nutritional factors causes sexual hormones to appear earlier so that adolescents tend to experience sexual development more quickly. The rise of adolescent sexual behavior at this time is increasingly concerning and tends to increase both in terms of the quantity and sharpness of cases that occur. Method: This type of research is an observational analytic with a cross-sectional study design, to analyze the exposure to reproductive health information on adolescent sexual behavior in Sleman Regency. Samples were taken from adolescents who were in class XI SMAN 2 Ngaglik with a purposive sampling technique of 198 students. Data collection using a questionnaire via google form. Data were analyzed using univariate, bivariate, and multivariate analyzes. Results: There is a relationship between reproductive health information from parents with adolescent sexual behavior (P value 0.00), there is a relationship between information from peers and adolescent sexual behavior (P value 0.00), there is a relationship between media access and adolescent sexual behavior ( P value 0.06) Adjusted RSquare value = 0.541. Conclusion: Of the three variables, information from parents and from peers has the same relationship with sexual behavior in adolescents, and media access is smaller than the other two variables

Die Soldering in Aluminium Die Casting

Two types of tests, dipping tests and dip-coating tests were carried out on small steel cylinders using pure aluminum and 380 alloy to investigate the mechanism of die soldering during aluminum die casting. Optical and scanning electron microscopy were used to study the morphology and composition of the phases formed during soldering. A soldering mechanism is postulated based on experimental observations. A soldering critical temperature is postulated at which iron begins to react with aluminum to form an aluminum-rich liquid phase and solid intermetallic compounds. When the temperature at the die surface is higher than this critical temperature, the aluminum-rich phase is liquid and joins the die with the casting during the subsequent solidification. The paper discusses the mechanism of soldering for the case of pure aluminum and 380 alloy casting in a steel mold, the factors that promote soldering, and the strength of the bond formed when soldering occurs. conditions, an aluminum-rich soldering layer may also form over the intermetallic layer. Although a significant amount of research has been conducted on the nature of these intermetallics, little is known about the conditions under which soldering occurs

Application of extraction replicas and analytical electron microscopy to precipitate phase studies

Extraction replicas provide a powerful extension of AEM techniques for analysis of fine precipitates. In many cases, replicas allow more accurate analyses to be performed and, in some cases, allow unique analyses which cannot be performed in-foil. However, there are limitations to the use of extraction replicas in AEM, of which the analyst must be aware. Many can be eliminated by careful preparation. Often, combined AEM studies of precipitates in-foil and on extraction replicas provide complementary and corroborative information for the fullest analysis of precipitate phases

Conquest and Form: Narrativity in Joshua 5-11 and Historical Discourse in Ancient Judah

One goal of this essay is to offer an exploratory, historiographical analysis of the conquest account in the book of Joshua, an analysis that focuses upon the sociocultural milieu of ancient Judah. I propose to show how this narrative of conquest might have contributed to discourse(s) among the literate Judean community that perpetuated the text, and I will offer a few thoughts on the potential relationship between the narrative and the supposed cultic reforms of the late seventh century b.c.e. A number of biblical scholars have argued that the late monarchic period gave rise to the conquest story as recounted in Joshua. In this essay, I would like to pay special attention to precisely how this narrative might have functioned within the milieu of the late monarchic period, thus refining our understanding of the narrative’s contribution to the discourses of this era and our knowledge of its relationship to other narratives that were probably extant at the same time. In other words, what particular features of the narrative might have had special import in this period? Specifically, I will argue that the narrative reveals certain discursive statements about Yahweh’s cultic supremacy and about important cultic sites in late monarchic Judah, and that this is evident in particular narratival features that are present in the text

Effects of proton irradiation on the microstructure and microchemistry of type 304L stainless steel

A research program has been undertaken to determine the origins of irradiation-assisted stress corrosion cracking (IASCC) in austenitic alloys in light water reactors, and the effect of impurities on IASCC susceptibility. Controlled purity alloys of 304L stainless steel were irradiated with protons at 400[deg]C to a dose of 1 dpa and analyzed via Auger electron spectroscopy (AES) and scanning transmission electron microscopy (STEM). The alloys investigated were an ultra-high purity (UHP) alloy and UHP alloys containing phosphorus (UHP + P), sulfur (UHP + S), or silicon (UHP + Si). Microstructural and microchemical changes were quantified and compared with literature results for other irradiating species. Following irradiation, the alloys showed dislocation loop formation and growth, "black dot" loops, and a change in the nature of the dislocation network. AES and STEM microchemical analysis of the alloys revealed Cr depletion of up to 6 at% and Ni enrichment of up to 6.6 at% at the grain boundaries of the alloys, with more segregation observed in the alloys containing impurities than in the UHP alloy. Significant grain boundary enrichment of P and Si in the UHP + P and UHP + Si alloys, respectively, was also observed. The results of the analyses of proton-irradiated samples are shown to compare favorably with previous studies on samples irradiated with neutrons at or near LWR conditions.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/30554/1/0000187.pd

Thermally-Induced Microstructural Changes in a Three-Way Automotive Catalyst

The use of advanced electron microscopy techniques to characterize both the bulk and near-atomic level microstructural evolution of catalyst materials during different dynamometer/vehicle aging cycles is an integral part of understanding catalyst deactivation. The study described here was undertaken to evaluate thermally-induced microstructural changes which caused the progressive loss of catalyst performance in a three-way automotive catalyst. Several different catalyst processing variables, for example changing the washcoat ceria content, were also evaluated as a function of aging cycle and thermal history. A number of thermally-induced microstructural changes were identified using high resolution electron microscopy techniques that contributed to the deactivation of the catalyst, including sintering of all washcoat constituents, {gamma}-alumina transforming to {alpha}-, {beta}-, and {delta}-alumina, precious metal redistribution, and constituent encapsulation. The data accumulated in this study have been used to correlate microstructural evolution with thermal history and catalyst performance during various aging cycles and to subsequently evaluate different washcoat formulations for increased thermal stability

Beam-broadening effects in STEM/EDS measurement of radiation-induced segregation in high-purity 304L stainless steel

Radiation-induced segregation (RIS) is the spatial redistribution of elements at defect sinks such as grain boundaries and free surfaces during irradiation. This phenomenon has been studied in a wide variety of alloys and has been linked to irradiation-assisted stress corrosion cracking (IASCC) of nuclear reactor core components. Therefore, accurate determination of the grain boundary composition is important in understanding its effects on environmental cracking. Radiation-induced segregation profiles are routinely measured by scanning-transmission electron microscopy using energy-dispersive X-ray spectroscopy (STEM-EDS) and Auger electron spectroscopy (AES). Because of the narrow width of the segregation profile (typically less than 10-nm full width at half-maximum), the accuracy of grain boundary concentration measurements using STEM/EDS depends on the characteristics of the analyzing instrument, specifically, the excited volume in which x-rays are generated. This excited volume is determined by both electron beam diameter and the primary electron beam energy. Increasing the primary beam energy in STEM/EDS produces greater measured grain boundary segregation, as the reduced electron beam broadening a smaller excited volume. In this work, the effect of beam broadening is assessed on segregation measurements in a 304L stainless steel sample irradiated with 3.2 MeV protons at 400 C to doses of 3.0 and 0.1 dpa. The STEM/EDS measurements are also compared to measurements made using AES

Quantitative analysis of radiation-induced grain-boundary segregation measurements

Radiation-induced and precipitation-induced grain-boundary segregation profiles are routinely measured by scanning-transmission electron microscopy using energy-dispersive X-ray spectroscopy (STEM-EDS). However, radiation-induced grain-boundary segregation (RIS) profiles achieved at low and moderate temperatures are exceedingly narrow, typically less than 10 nm full width at half maximum. Since the instrumental spatial resolution can be a significant fraction of this value, the determination of grain boundary compositions poses a formidable challenge. STEM-EDS and Auger electron spectroscopy (AES) measurements are reported, performed on controlled-purity alloys of type 304L stainless steel irradiated with 3.4 MeV protons to 1 displacement per atom at 400[deg]C. Because of statistical noise and the practical lower limit on the step size in STEM, deconvolution of the measured data does not yield physical results. An alternative analysis of STEM data is presented. Numerical calculations of RIS profiles are convoluted with the instrumental broadening function and modified iteratively to fit the data, yielding a "best estimate" profile. This "best estimate" is convoluted with the Auger intensity profile to yield a simulated AES measurement, which is compared with the actual AES measurement to provide an independent test of the validity of the "best estimate". For impurities with a narrow segregation profile and an Auger electron escape depth of one monolayer, a combination of STEM and AES data allows a determination of the width of the segregated layer. It is found that, in an ultrahigh-purity alloy doped with P, the latter is essentially contained in a single monolayer.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/31453/1/0000374.pd
