Authenticity test of the processed meat products

Different and related approaches must be considered to address consumers' concerns regarding the identification of species involved, mainly those of manufactured and derived meat products such as cured and canned meat and canned sausage. Therefore, the development of molecular techniques has been achieved by a mixture containing different shares of meat DNA. This study provided an important indication regarding the validity of the multiplex Polymerase Chain Reaction (PCR) technique in such tests. Based on the fact that the aforementioned method is qualitative; yet, the different percentages of meat DNA contained in the mixtures cannot be determined. Our current study showed that tracing back the origin of the ingredients used in food production is achievable, even if the DNA is degraded as a result of the food transformation processes. A PCR test was conducted at 35 cycles for mixtures at 100%, 75%, 50%, and 25% levels. Our results indicated that the original species of the meat products used were accurately determined in all mixtures tested by PCR technique. Therefore, we concluded that the PCR technique can be useful as a fast, easy to perform, and reliable control for adulterated consumer meat products.

Modelling and simulations for signal loss evaluation during sampling phase for thermoluminescence authenticity tests

<p class="Abstract"><span lang="EN-GB">In authenticity tests using the thermoluminescence (TL) method, the sampling phase is fundamental to collecting an appropriate amount of powder for analysis. The powder is usually obtained by drilling in hidden and pertinently selected areas of an artefact. During the drilling, a local temperature increase can occur, and, because thermoluminescence emission is dependent on the heating rate, the authenticity test result could be invalidated due to underestimation of the signal intensity. In this work, the percentage of signal intensity loss is investigated through the combination of a dynamic electro-mechanical model and a typical TL glow curve simulation. After first modelling the drilling procedure to estimate the maximum temperature reached, the optimal parameters that should be used during the sampling phase are checked by simulations together with an evaluation of the correlated signal losses.</span></p>

A Study of Various Types of Natural Marble Towards Their Use in Cultural Applications

Marble has been used as decorative or building material since ancient times. Various archaeological marble materials of cultural heritage (e.g., statues) are frequently encountered in excavation sites amongst other finds. The scope of the present work is to investigate whether natural marble could be used for dosimetric purposes in cultural applications, such as dating or authenticity test of ancient marble objects, through an integrated experimental approach. For this purpose, the chemical composition, structure/morphology, and luminescence properties of 11 different types of natural marble of different origin (from various geographical regions) were examined by means of micro-x-ray fluorescence spectroscopy, stereoscopic microscopy, thermoluminescence (TL), and optically stimulated luminescence (OSL), respectively. Results indicate that though TL and OSL could be used for the identification of the marble type (origin), the use of natural marble for dosimetric purposes using these methods requires the a-priori knowledge of its type along with some of the main luminescence properties.

HERMENEUTIKA KHALED M. ABOU EL FADL TENTANG KONSEP OTORITARIANISME DALAM HUKUM ISLAM

Khaled M. Abou el-Fadl is one of the contemporary Islamic thinkers who offers a model of reading religious texts which he considers authoritative. The phenomenon of authoritarianism or self-determination in the name of religion and God in Islamic thought, according to Khaled M. Abou el-Fadl, happens a lot as evidenced in his research which focuses on the study of Islamic law that has been carried out by Wahabi puritans in the CRLO fatwa institutions that provide many fatwas which is considered to be very gender biased. Khaled M. Abou el-Fadl offers authoritative hermeneutics as a criticism as well as a methodological tool for dissecting and interpreting Islamic texts, specifically in the realm of Islamic law, namely by paying attention to three things, First, relating to competence (authenticity test); second, related to accuracy; third, with regard to representation in Islam

Implementasi Model Pembelajaran BCCT (Beyond Centers And Circle Times) dan Model Pembelajaran Konsiderasi di TK Khalifah Baciro Kota Yogyakarta

This study aims to provide an overview of the implementation of the BCCT learning model and the consideration learning model in TK Khalifah Baciro, Yogyakarta City. This research method uses qualitative research. The subjects of this research were 4 class teachers, 1 school principal and 36 students. Data collection uses observation, interviews, and documentation. The data analysis uses the Huberman Milles Model. The authenticity test uses triangulation of techniques and sources. The results showed that the BCCT learning model and consideration can be used as a reference for early childhood education institutions as an effort to develop aspects of creative and innovative child development. In addition, considerations of the learning model can shape the character of the child's mercy, such as manners, good character and good behavior.

A Decision-Aided Situation Awareness Mechanism Based on Multiscale Dynamic Trust

Attacks are always seeking ways of exploiting any existing weakness in wireless network. The purpose of security situation awareness is to recognize, analyze, forecast, and handle the misbehaviors, assisting network management. Nevertheless, the appearance of ubiquitous network and the network convergence technology has made a challenge to realize network security and adaptation. Aiming at these research problems, this paper proposes a decision-aided situation awareness mechanism based on multiscale dynamic trust from the perspective of time and space, which can recognize misbehaviors and regard social network as the research object. We build trust and satisfaction based on Ebbinghaus forgetting regular and spatial correlations. This mechanism carries out decision making assessment through trust authenticity test, logicality test, and feedback parameters. In addition, load balance is used to avoid resource congestion. Simulation analysis demonstrates that compared with other trust mechanisms, this mechanism proposed in this paper can recognize and handle entity attacks more effectively, which is relatively eclectic and realistic in aspect of trust mensuration.
