Time-gated Raman and laser-induced breakdown spectroscopy in mapping of eudialyte and catapleiite

2020

Raman analysis of rock samples containing rare earth elements (REEs) is challenging due to the strong fluorescence, which may mask the weaker Raman signal. In this research, time‐gated (TG) Raman has been applied to the construction of the mineral distribution map from REE‐bearing rock. With TG Raman, material is excited with a short subnanosecond laser pulse, and the Raman signal is collected within a picosecond‐scale time window prior to the formation of a strong fluorescent signal by means of single‐photon avalanche diode array. This allows signal readout with a significantly reduced fluorescence background. TG Raman maps are used to reveal the location of valuable minerals and are compa…

Compact Quantum Circuit Design of PUFFIN and PRINT Lightweight Ciphers for Quantum Key Recovery Attack

2023

Quantum computing plays a vital role in the next generation computing platforms as researchers have achieved quantum supremacy by proving that quantum computers can outperform classical computers. These high performance computers will pose a serious threat to the security of the conventional cryptographic algorithms. The secret key of the conventional cryptographic algorithms when implemented by quantum circuits can easily be recovered with the help of Grover key search algorithm. The Grover’s algorithm requires low cost quantum implementation of cryptographic algorithms in order to mount the quantum key recovery attack successfully. Hence the low cost quantum implementation of conventional…

A methodological look at the controversy about the influence of salt intake on cardiovascular risk

2012

Cardiovascular diseases are a major cause of premature death and disability. They represent an extraordinarily strong financial burden upon health-care systems in ‘‘developed’’ countries. Elevated blood pressure is a major cause of cardiovascular disease. There is much evidence that cardiovascular risk increases from normal blood pressure (i.e., from 115/75 mmHg upwards) [1]. Overwhelming evidence shows that reducing salt intake from 9–12 g/day to 5–6 g/day lowers blood pressure [2]. Blood pressure is a surrogate endpoint, but may be related to a reduction of morbidity and mortality due to cardiovascular causes. Thus, intensive support and encouragement to cut down on the intake of salt in …

Soil aggregates, organic matter turnover and carbon balance in a Mediterranean eroded vineyard

2014

The carbon cycle is being affected by the human impacts (Novara et al., 2011; Yan-Gui et al., 2013), and one of those is the intensification in the soil erosion in agriculture land (Cerdà et al., 2009; García Orenes et al., 2009). Vineyards also are affected by the human activities (Fernández Calviño, 2012). Vineyards in Sicily are cultivated on 110.000 ha, 10% of which on >10% slope. Deficiencies of soil organic matter are typical of the semi arid Mediterranean environment especially where traditional intensive cropping practices are adopted (Novara et al., 2012; 2013). These practices in vineyards could lead soil to intensive erosion processes (Novara et al., 2011). The fate of SOC under …

Hierarchies of knowledge, incommensurabilities and silences in South African ECD policy: Whose knowledge counts?

2017

AbstractPolicy for young children in South Africa is now receiving high-level government support through the ANC’s renewed commitment to redress poverty and inequity and creating ‘a better life for all’ as promised before the 1994 election. In this article, I explore the power relations, knowledge hierarchies and discourses of childhood, family and society in National Curriculum Framework (NCF) as it relates to children’s everyday contexts. I throw light on how the curriculum’s discourses relate to the diverse South African settings, child rearing practices and world-views, and how they interact with normative discourses of South African policy and global early childhood frameworks. The NCF…

Can the students' career performance be helpful in predicting an increase in universities income?

2013

The students’ academic failure and the delay in obtaining their final degree are a significant issue for the Italian universities and their shareholders. Based on indicators proposed by the Italian Ministry of University, the Italian universities are awarded a financial incentive if they reduce the students’ attrition and failure. In this paper we analyze the students’ careers performance using: 1) aggregate data; 2) individual data. The first compares the performances of the Italian universities using the measures and the indicators proposed by the Ministry. The second analyzes the students’ careers through an indicator based on credit earned by each student in seven academic years. The pr…

Aizsarglietu stāstījumu folklora Latgalē (pēc 2018. un 2019. gada lauka pētījumu materiāliem)

2019

Bakalaura darba tēma ir “Aizsarglietu stāstījumu folklora Latgalē (pēc 2018. un 2019. gada lauka pētījumu materiāliem)”. Bakalaura darba mērķis bija noskaidrot, kas ir raksturīgs aizsarglietu stāstījumu folklorai Latgalē, kāda ir tās specifika, vai un kā ir transformējušās ar aizsarglietām saistītās latviešu tautas tradīcijas, salīdzinot ar latviešu folkloras materiālu. Darbs sastāv no ievada, trim nodaļām un, secinājumiem. Pirmajā nodaļā tika analizēti aizsarglietu stāstījumi, kas vēsta par mājas aizsardzību (māju, īpašumu aizsargājošiem augiem, ornamentālajām zīmēm, baznīcā svētītajām aizsarglietām), un tika noskaidroti aizsarglietu izmantošanas dažādie nolūki. Otrajā nodaļā tika raksturo…

The surrogate family is a family form of surrogate custody, with the use of which the state as a substitute for biological families provides children with a caring and educational function. The placement of a child in a surrogate family: relative, non-professional or professional family belongs to the family court competence, while public administrations are obliged to provide social infrastructure in this regard, and in particular to create a family base suitable for the needs of the county. Family surrogate organizer with family surrogate coordinators cooperate with thesefamilies. A surrogate family can be a single person or a family, such a function can not lead a free relationship. As a…
