Multi-regression analysis between stable isotope composition and hydrochemical parameters in karst springs to provide insights into groundwater origin and subsurface processes: regional application to Lebanon
No full textJoint applications of isotope characterization using δ2H, δ18O and geochemical analyses have allowed for a better conceptualization of hydrological systems and helped in the evaluation and management of water resources. Processes of infiltration, and evapotranspiration (ETP), as well as mixing in the unsaturated zone, incur changes in the meteoric δ2H-δ18O signal that is transferred to groundwater during recharge. Previous studies on the isotopic composition of atmospheric precipitation highlight the importance of rainwater differentiation in terms of chemical composition and isotopic signature as a function of topographical and orographic variations as well as natural and anthropogenic impacts and identified altitude gradients for both δ2H and δ18O. In this work, a comparative correlative analysis of stable oxygen and deuterium isotopes was conducted on selected Lebanese springs. At the first stage, a hydrochemical analysis allowed the characterization of the springs and their clustering according to their predominant ionic content and aquifer units. Additionally, a multi-regression analysis reveals a relationship between hydrogen and oxygen isotopes and other easily measured parameters at the spring such as temperature, electrical conductivity, elevation, and easting and northing. The obtained relationship validated on a second campaign was attributed qualitatively to the extent and elevation of the spring catchment, the depth of flow, mixing, the snow effect, and residence time. Moreover, outliers characterized by a very large catchment area or allochthonous recharge could be outlined in the set of investigated springs. The results show that the stable isotopic signature indicative of recharge areas can be inferred based on easily measured spring parameters and can, therefore, help in the identification of protection zones and direct areas of spring recharge from a regional dataset. © 2021, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature
Integrated Numerical Modelling of Groundwater Flow in the Upper Litani Basin: Testing the Need of Managed Aquifer Recharge
No full textAlameddine, Ibrahim
Salah, MohamedGroundwater resources management has been a growing concern as the consequences of climate change and other anthropogenic forces have heavily impacted freshwater resources, especially in semi-arid regions. The adoptions of managed aquifer recharge (MAR) remains at its earliest stages of assessment in developing countries such as Lebanon. Regional conflicts and the current refugee status have amplified the need for accessible uncontaminated freshwater resources in the semi-arid Bekaa region. At a pilot scale, this thesis investigates the hydraulic properties of a well drilled in the Miocene alluvial consolidated deposits in the Litani Basin, Bekaa in Lebanon, which is
devised to store surface runoff during the winter, to be utilized for agricultural irrigation purposes in the summer (Aquifer Storage and Recovery scheme). The small scale subsurface characterization of aquifer properties was done using grain size analysis of borehole cuttings and several pumping tests to assess transmissivity in the recharged aquifer at the borehole scale. In the latter case, water availability poses a challenge on the sustainability of MAR. To answer this question, an integrated hydrological model was constructed and calibrated using MIKE SHE (DHI, 2017a) for the entire Upper Litani Basin (ULB) catchment to simulate flow in steady-state for the years 1970 and 2010 based on existing water level data to evaluate the water balance in the area including lateral and return flow and recharge to groundwater) in comparison to pumping and river exchange. Transient flow was simulated to assess the degree of groundwater depletion, the availability of water resources, and recharge during high
flow periods while accounting for the different hydrological components; namely climate, river, saturated and unsaturated zone. The model serves as an integrated decision support tool to predict the change in groundwater levels in the future under climate change scenarios and to ensure proper sustainable water management. Additionally, the testing of the sensitivity of model output to model parameters will help refine model uncertainty and identifies the need for specific additional measurements to be implemented on the ULB
What Does It Mean to Say That Procedure Is Political?
No full textProcedure is not the first field of law to face controversy along these lines. Law’s independence from politics, in both its descriptive and normative aspects, is a century long legal challenge.9 This Article aims to clarify what we mean when we characterize procedure as political, as well as to understand some of the harms generated by failing to confront and acknowledge the political. This is a preliminary step in approaching future formulations of procedural rules if they cannot be depoliticized

No full textPurpose:
This paper deals with the legal regulation of Estonia’s public order from the aspect of local governments. The purpose of the article is to analyse relevant Estonian legislation to help identify problems and make suggestions for improvement. Proposals are intended for the institutions involved in developing legislation in Estonia. Local governments in the country act according to the Constitution of the Republic of Estonia (1992), but still retain enough legal autonomy to decide on local affairs independently of the state government.
Methods:
The paper is based on an analysis of national legislation. In the legal research, the author pays attention to written sources of law, e.g. the Constitution of the Republic of Estonia (1992), and subsequent legal acts regulating public order.
Findings:
The main task of local government is to provide public services and improve the quality of the living environment. In Estonia, the principal provider of internal security is the Police and Border Guard Board. It is the responsibility of local government to assist the national structures in fulfilling their duties. On the other hand, the municipalities are required to ensure public order within their territories. The legal power given by parliament to local governments to carry out such activities is insufficient to ensure the law is enforced.
Practical Implications:
The findings in this paper highlight areas in which the legal regulation could be improved.
Originality/Value:
Although the legal basis for Estonian municipalities’ operations has been studied carefully, it is necessary to examine issues concerning the links between local governments and public order in detail. The continually changing legislation makes the situation complex to handle. It also provides an opportunity for international comparative analysis with other European Union member states.Namen prispevka:

Provedba crkvenog nauka o liturgijskoj inkulturaciji u Indoneziji. Slučaj reda mise na indonezijskom jeziku
No full textThough the term inculturation is a neologism, as a practice, it has been implemented by the Church since its birth. The issue of inculturation is indeed a global Church concern but has become more urgent for young Churches, including the Catholic Church in Indonesia. This article raises the problematics of liturgical inculturation in the Indonesian Catholic Church, hoping it can reflect similar issues on a broader scale. The author focuses on the implementation of the Catholic Church's teachings on liturgical inculturation, discussing the case of the formulation process of the Order of Mass in the Indonesian language. This article is based on library research examining the Church's teachings on liturgical inculturation and their implementation within the Indonesian Catholic Church through a case study of the formulation of the Order of Mass in the Indonesian language. The findings present the dynamics of liturgical inculturation movements in the Indonesian Catholic Church, ranging from strong enthusiasm – sometimes exceeding boundaries – to efforts to faithfully adhere to Church liturgical traditions in line with established norms. To a certain extent, the formulation process of the Order of Mass in the Indonesian language illustrates the practice of liturgical inculturation in Indonesia.Iako je pojam »inkulturacija« novotvorenica, kao praksu Crkva ju provodi od svog rođenja. Pitanje inkulturacije uistinu je crkveno pitanje u cijelom svijetu, ali postalo je hitnije za mlade Crkve, što uključuje i Katoličku Crkvu u Indoneziji. Ovaj članak želi pokrenuti problematiku liturgijske inkulturacije u Katoličkoj crkvi Indonezije u nadi da može poslužiti kao odraz sličnih problema u širim okvirima. Autor se usredotočuje na članak o provedbi nauka Katoličke Crkve o liturgijskoj inkulturaciji raspravljajući o slučaju procesa oblikovanja Reda mise na indonezijskom jeziku. Ovaj je članak bibliotečno istraživanje koje se temelji na nauku Crkve o liturgijskoj inkulturaciji i nastoji oko njegove provedbe u indonezijskoj Katoličkoj crkvi kroz studiju slučaja formulacije Reda mise na indonezijskom jeziku. Rezultat ovog istraživanja predstavit će postojeću dinamiku liturgijskih inkulturacijskih pokreta u indonezijskoj Katoličkoj Crkvi, koja se kreće od snažnog entuzijazma, koji može ići preko granica, do nastojanja da se poslušno slijedi tradicija crkvene liturgije u skladu s postojećim liturgijskim normama. U određenoj mjeri proces oblikovanja Reda mise na indonezijskom jeziku može prikazati praksu liturgijske inkulturacije u Indoneziji
Design-time and Run-time Reconfigurable Clustered ?-VEX VLIW Softcore Processor
No full textThe ?-VEX processor is a parameterized reconfigurable Very Large Instruction Word (VLIW) softcore processor. It can be reconfigured in the issue-width, number and type of functional units (FUs), width of memory buses and number of registers in the multi- ported register file. The current design of the ?-VEX processor supports single cluster processor organization. The design also provides run-time dynamic reconfigurability between different processor architectures. As the issue-width of the processor increases, the number of read and write ports from the FUs to the register file increases which enlarges its area utilization. This increase in the number of read and write ports is not scalable with the interconnect wires available in the current IC technology. From literature, we know that clustering the FUs of the processor and splitting up the register file into a smaller subsets significantly reduces the area overhead and power consumption. In this thesis, we have developed all the necessary hardware and software components to enable the design-time and run-time reconfigurable ?-VEX processors to support clustered organization. Those development are the design and implementation of inter- cluster communication FUs, inter-cluster path and local register file per cluster and the adaptation of the compiler toolchain. As an inter-cluster communication model (ICC), copy operation and dedicated issue slot ICC model are implemented. The cycle count and total operations of different benchmark applications are measured and analyzed on the clustered organization of ?-VEX processors. The cycle count for most of the benchmarks is higher in clustered organization except for applications with high instruction level parallelism such as matrix and adpcm. A speedup of 3.04× is achieved by matrix benchmark. On the other hand, an increase in code size of the benchmark applications is measured for the clustered processor by a maximum of 38%. The area utilization of the 4-issue and 8-issue design-time reconfigurable ?-VEX processors are significantly reduced by up to 74% by clustering them into two clusters. In addition, a speedup of 1.55× is obtained on the clock frequency of the processor. Similarly, the run-time reconfigurable clustered ?-VEX processor occupies 61.3% less area, consumes up to 41.6% less dynamic power than the single clustered processor and has a reduced energy delay product (EDP).Embedded SystemsMicroelectronics & Computer EngineeringElectrical Engineering, Mathematics and Computer Scienc

Abstract
Type 2 diabetes in more than 70% of cases is caused by overweight and obesity. In many cases, a proper diet and increased physical activity are effective in the prevention and treatment of insulin resistance and pre-diabetes, which usually prevents the development of the disease. However, the recommendations for physical activity in type 2 diabetics differ from those for healthy people. The paper presents an analysis of recommendations concerning physical activity in the prevention and treatment of type 2 diabetes.
Key words: diabetes, obesity, insulin resistance, physical activit
Backdoor Attack on gaze estimation
No full textBadnets are a type of backdoor attack that aims at manipulating the behavior of Convolutional Neural Networks. The training is modified such that when certain triggers appear in the inputs the CNN is going to behave accordingly. In this paper, we apply this type of backdoor attack to a regression task on gaze estimation. We examine different triggers to discover which of them lead to better performance and thus infer which trigger aspects one can take the most advantage from. It turns out that placing frames around and drawing multiple lines across the images are the most effective for the training of Badnets.CSE3000 Research ProjectComputer Science and Engineerin
Adolescents' use of media: links with parental control and behavioral-emotional difficulties.
No full textAdolescents tend to use the media to find a supportive community, but media use can also be associated with adolescent internal or external difficulties. Since most research is based on young adults ’use of media, it is unclear how well their findings apply to adolescents who have never known a world without media. No studies have been found to discuss the peculiarities of media use among adolescents aged 14–19, the analysis of the links with perceived parental control, and the behavioral-emotional difficulties of adolescents. The aim of the study was to identify the peculiari-ties of media use among adolescents aged 14–19 and to reveal their connections with perceived pa-rental control and behavioral-emotional difficulties. Peculiarities of media use among adolescents aged 14–19 and links with perceived parental control and behavioral-emotional difficulties in this work were investigated using a questionnaire on personal devices (media) and time spent using media (compiled by the author of this paper), Social Media Use Measure (Seo, Houston, Knight, Kennedy & Inglish, 2014a,b), Online Activities Measure (Livingstone ir Görzig, 2014), Parental Control Questionnaire of Internet Use in Ado-lescence (isp. Cuestionario de Control Parental del Uso de Internet durante la Adolescencia, Alva-rez-Garcia, Garcia, Cueli & Nunez, 2018a), SDQ (Goodman, Ford, Simmons et al., 2000; Gintilienė ir kt., 2004) and sociodemographic questions (compiled by the author of this paper). This study found that most teens have and use a smartphone, computer, and TV. Girls are more likely to use a TV, tablet and radio, while guys are more likely to use a game console. The ave-rage time of using media per day is 6.17 hours. The timing of media use does not differ between girls and boys. Girls are more likely to visit social media profiles, do schoolwork, read news and e-mails, and use a webcam, while guys are more likely to play games alone and against the computer and with other people. Adolescents perceive parental control as very insignificant. The greater the subjectively perceived parental control over the media use is, the less time adolescents spend on the media. Adolescent hyperactivity, emotional symptoms, behavioral difficulties, and difficulties with peers are normal. Adolescents with more behavioral-emotional difficulties spend more time online and are more likely to use media just to spend time, or to feel better
