Pengembangan Material Serbuk Silika Untuk Identifikasi Sidik Jar!

Development of powder material for fingerprint identification has become Indonesian Department of Safety and Defense priority, especially it was written in the National Research Agenda 2006 -2009. Until now Indonesia still imported thepowder from United States and Japan. Powder fineness is one of the important factors, because finer the powder, more easily it stick to the latent fingerprint and better visualization result will be obtained. In this research, nanosilica was fabricated by used TEOS (tetraethoxysilane) as precursor. Nanosilica is an adhesive material in fingerprint powder while carbon is a coloring agent. In this research nanosilica and carbon black composition was optimized, and the powders were characterized and tried in order to get afingerprint powder which have a better quality to be used by National Police and therefore it can support Indonesian autonomy in safety and defense

Quantum test of the equivalence principle for atoms in superpositions of internal energy eigenstates

The Einstein Equivalence Principle (EEP) has a central role in the understanding of gravity and space-time. In its weak form, or Weak Equivalence Principle (WEP), it directly implies equivalence between inertial and gravitational mass. Verifying this principle in a regime where the relevant properties of the test body must be described by quantum theory has profound implications. Here we report on a novel WEP test for atoms. A Bragg atom interferometer in a gravity gradiometer configuration compares the free fall of rubidium atoms prepared in two hyperfine states and in their coherent superposition. The use of the superposition state allows testing genuine quantum aspects of EEP with no classical analogue, which have remained completely unexplored so far. In addition, we measure the Eotvos ratio of atoms in two hyperfine levels with relative uncertainty in the low $10^{-9}$, improving previous results by almost two orders of magnitude.Comment: Accepted for publication in Nature Communicatio

DYSPHORIA DIMENSIONAL MODEL FOR FEEDING AND EATING DISORDERS: A PRELIMINARY STUDY

Background: Anorexia Nervosa (AN), Bulimia Nervosa (BN) and Binge Eating Disorder (BED) are severe psychiatric illnesses which represent the main expression of Feeding and Eating Disorders (FED). Clinicians agree that emotional and behavioural dysregulation play a crucial role in FED. Dysphoria could help us to better understand these components. Indeed, we define dysphoria as a generic state of dissatisfaction and emotional instability, without any specific features. Among the multitude of symptoms, we find that irritability, discontent, interpersonal resentment and surrender prevail. These dimensions correspond to the four subscales of Neapean Dysphoria Scale - Italian version (NDS-I). Dysphoria role in FED has not yet been investigated. Using this test, we can characterize dysphoria both in quantitative and qualitative terms. Accordingly, domain evaluation could discriminate these disorders allowing us to assess possible differential phenomenological expressions. Aims: The aim of this paper is to understand in which way the dimensional spectrum that composes dysphoria differs between Anorexia Nervosa, Bulimia Nervosa and Binge Eating Disorders through an observational comparative study. Subjects and methods: The enrolled sample (30 patients) is represented by patients with a history of FED (AN, BN or BED). Patients were males and females between the ages of 13 and 45 with a good knowledge of Italian language. Patients with severe cognitive impairment (MMSE <19) and civil incapacitation were excluded. Patients were recruited from the Psychiatric Service of the Santa Maria della Misericordia Hospital in Perugia (PG), and other residential and semi residential structures specialized in FED treatment (FED specialized center at Palazzo Francisci in Todi (PG), Nido delle Rondini in Todi (PG), BED (Binge Eating Disorders) center in Città della Pieve (PG) and ambulatory services for FED in Umbertide (PG)). We administered them the Neapen Dysphoria Scale – Italian Version (NDS-I), a specific dimensional test for dysphoria. Starting from the dataset, with the aid of the statistical program SPSS 20, we have carried out a comparison between disorders groups selected and NDS-I total score and subscales (irritability, discontent, interpersonal resentment, surrender). For this we have used the Mann-Whitney U test, a nonparametric test with 2 independent samples, by setting a significance level p<0.05. Conclusions: This study allowed us to better understand and characterize the most common Eating Disorders. Beyond that, despite the small sample size, we found in our analysis statistically significant difference in the expression of various dysphoria dimension spectrum inside our 3 groups

An overview of temperature issues in microwave-assisted pyrolysis

Microwave-assisted pyrolysis is a promising thermochemical technique to convert waste polymers and biomass into raw chemicals and fuels. However, this process involves several issues related to the interactions between materials and microwaves. Consequently, the control of temperature during microwave-assisted pyrolysis is a hard task both for measurement and uniformity during the overall pyrolytic run. In this review, we introduce some of the main theoretical aspects of the microwaves&ndash;materials interactions alongside the issues related to microwave pyrolytic processability of materials
