The European peripherality index

Article 2 of the Maastricht Treaty states as the goals of the European Union the promotion of harmonious and balanced economic development, convergence of economic performance, improvement of the quality of life and economic and social coherence between the member states. A prominent role for the achievement of these goals play the envisaged Trans-European Transport Networks (TETN). They are to link landlocked and peripheral areas with the central areas of the Community. The identification of those peripheral regions, whose accessibility and transport infrastructure systems are to be improved, is becoming of great political importance. This is underlined by the European Commission's first Cohesion Report (1997) which emphasises that "regions should ensure that policy success is measurable, that results are regularly monitored, and that the public and political authorities are regularly informed of progress." This paper presents the results of a study on peripherality undertaken for the European Commission. The purpose was to undertake, for the fifteen EU states and twelve candidate countries, the calculation of an index of peripherality of the 'potential' type. The economic potential of a region is the total of destinations in all regions weighted by a function of distance from the origin region. It is assumed that the potential for economic activity at any location is a function both of its proximity or 'travel tim' to other economic centres and of its economic size or 'mass'. The influence of each economic centre on any other centre is assumed to be proportional to its volume of economic activity and inversely proportional to a function of the distance between them. The economic potential of a given location is found by summing the influence on it of all other centres. Based on theoretical considerations, an integrated European Peripherality Index software system was developed to facilitate peripherality indices calculatio scenarios comparison, data updating and results demonstration. It is designed in a way to evaluate the impacts of transport infrastructure projects as well as impacts of general transport policies with respect to peripherality and could be seen as a first attempt for a wider regional monitoring system. In this, it should contribute to answer the debated question whether infrastructure improvements rather lead to cohesion effects or whether they increase disparities between the regions. The paper starts with theoretical considerations on cohesion effects of transport infrastructure improvements and concepts of accessibility and peripherality. Then the methodology used and the software system developed will be addressed briefly. Eventually the results of the indicator calculations will be presented, before the paper concludes with political implications and findings.

Removal of lead from industrial wastewater using a low cost waste material

Several industries utilize heavy metals in their industrial processes, eventually discharging them in their wastewater. Water contamination by heavy metals is a major environmental problem due to their acute toxicity and their accumulation in food chains. Therefore, intensive research work has been carried out lately on the feasibility of various low cost materials for the removal of heavy metals from wastewater. The main objective of the current research was to examine the potential of a low cost material for the removal of Pb2+ from a synthetic lead solution. The research work was divided into three core phases. Phase I was a preliminary comparative study among various agricultural wastes; sugarcane bagasse, rice straw and rice husk, two industrial wastes, namely cement kiln dust (CKD) and marble powder, and a natural material; lime. In Phase II the research was taken to a deeper level as the feasibility of utilizing rice straw for biosorption of Pb2+ was profoundly investigated using batch equilibrium experiments. The effect of several operating parameters on the uptake of Pb2+ was tested, which are the pH of the solution, contact time, rice straw dose, particle size, initial Pb2+ concentration and pre-treatment of rice straw. The percent removal of Pb2+ increased with increasing the pH, contact time, and rice straw dose up to the point of equilibrium; however, it decreased with the increase in the particle size. The pre-treatment of rice straw did not yield a considerable increase in the percent uptake of Pb2+. Langmuir and Freundlich isotherm models were used for the evaluation of the equilibrium experimental data; the correlation coefficients were 0.989 and 0.959, respectively. The maximum adsorption capacity of raw rice straw was calculated using Langmuir isotherm; 42.55 mg/g, which is higher than several adsorption capacities of rice straw reported in the literature. Phase III was conducting fixed-bed column experiments using rice straw. The service time of the columns and the treated volume of wastewater to breakthrough (Ce= 1mg/l) and to exhaustion (Ce≈ 95% C0) increased with the increase in the bed depth of the packed rice straw; however, they decreased with the increase in the initial Pb2+ concentration and the flow rate of the solution. Physical and chemical characterization of rice straw was carried out in order to define the BET surface area, pore volume, average pore size, surface functional groups, shape of the cell wall and chemical composition. Biosorption of Pb2+ using rice straw was inferred to be due to a complex of physical and chemical mechanisms

The potential impact data of Tylosin and Enrofloxacin veterinary antibiotics on germination and accumulation in barley seed as a forage crop and good dietary sources using LC/MS-MS

In this study, the phytotoxic effects caused by the exposure to five different concentrations of two veterinary antibiotics (Tylosin, and Enrofloxacin) that are commonly used for the treatment of farm animals as antibacterial agents were considered. The impact of antibiotic residues was evaluated on the germination percentage, accumulation, and seedling elongation of the barley seeds using Petri dishes under controlled environmental conditions. The treatments were distributed randomly using Completely Randomized Design (CRD). The germination percentage was significantly inhibited with the increasing Enrofloxacin dose concentrations, while, it was to some extent on the contrary in the case of Tylosin, where seed germination was enhanced as a result of increasing Tylosin concentrations.Liquid chromatography-tandem mass spectrometry LC/MS-MS was used to detect and quantify the uptake dosage after drying and extracting the antibiotic compounds from the seedling

Praćenje akcesornih spolnih žlijezda i testisa u ovnova pasmine barki pomoću Dopplera i ultrazvuka u B modu tijekom rasplodne sezone

The aim of this study was to perform ultrasonographic imaging of the testes and accessory sex glands in adult Barki rams during the breeding season. The impact of testosterone on the Doppler indices of accessory sex glands was also investigated. Scrotal contents, pelvic urethra and accessory sex glands of twelve mature Barki rams were scanned with multiple imaging of B-mode and colour Doppler ultrasonography. Serum concentrations of testosterone, FSH and LH were determined. The results revealed that the breeding season changed the echogenicity of testicular parenchyma, spermatic cord, epididymal tail, glans penis and echotexture of accessory sex glands. Serum testosterone was 7.27±0.37 ng/mL, FSH was 6.46±0.2 and LH was 5.6±0.28 m IU/mL. The pulsatility index (PI) for the supra-testicular artery (STA), marginal artery (MA) of the testes and epididymal tail was 1.01±0.07, 0.58±0.04 and 0.5±0.04. The resistive index (RI) for the same structures was 0.6±0.04, 0.33±0.04 and 0.3±0.03, respectively. Importantly, testosterone downregulated PI and RI of the ampulla, vesicular gland, prostate gland and bulbourethral gland. In conclusion, the breeding season changed the echogenicity of reproductive organs and accessory genital glands of rams, and testosterone regulated the hemodynamic parameters of the accessory sex glands.Ovo je istraživanje provedeno radi uspostavljanja normalnog ultrazvučnog (UZV) snimanja testisa i akcesornih spolnih žlijezda u odraslih ovnova pasmine barki tijekom rasplodne sezone. Osim toga, istraživan je i utjecaj testosterona na akcesorne spolne žlijezde temeljem uporabe Dopplera. Višestrukim snimanjem u B-modu i ultrazvučnim kolor Dopplerom pretraživan je sadržaj skrotuma, zdječna uretra te akcesorne spolne žlijezde u 12 odraslih ovnova pasmine barki. Određivane su serumske koncentracije testosterona, FSH i LH. Dobiveni su rezultati pokazali da u rasplodnoj sezoni dolazi do promjena u ehogenosti parenhima testisa, sjemenskog užeta, repa epididimisa, glansa penisa i ehoteksture akcesornih spolnih žlijezda. Razina serumskog testosterona iznosila je 7,27±0,37 ng/mL, FSH 6,46±0,2, a LH 5,6±0,28 m IU/mL. Pulzirajući indeksi (PI) supra arterije testisa (SAT), periferne arterije (PA) testisa i repa epididimisa bili su 1,01±0,07, 0,58±0,04, odnosno 0,5±0,04. Istovremeno, indeksi rezistentnosti (RI) gornjih kriterija su bili 0,6±0,04, 0,33±0,04, odnosno 0,3±0,03. Važno je spomenuti da je testosteron snižavao PI i RI ampule (a), vezikularne žlijezde, prostate i bulbouretralne žlijezde. Zaključno, rasplodna je sezona utjecala na promjene ehogenosti reproduktivnih organa i akcesornih spolnih žlijezda u ovnova. Nadalje, testosteron je regulirao hemodinamične pokazatelje akcesornih spolnih žlijezda tijekom rasplodne sezone u ovnova

Factors Contributing To Therapeutic Compliance Of Epileptic Patients And The Suggestive Solutions

Epileptic seizures are only one manifestation of neurologic or metabolic diseases. Epileptic seizures have many causes, including a genetic predisposition for certain seizures, head trauma, stroke, brain tumors, alcohol or drug withdrawal, and other conditions. . Several factors affect patient's level of adherence. These factors include type of therapy, patient's own condition, health team, social and financial support patient's psychological condition . The aim; of  this work is to detect the factors  affecting  compliance to therapeutic regimen among adult patients with epilepsy and the suggestive solutions for the main factors of noncompliance. Methodology; two tools were used in the study; epilepsy self-adherence scale and interviewing questionnaire to identify factors affecting compliance. Setting; Epilepsy outpatient clinic, Ain Shams University hospital Sample: A convenience sample of (50) adult female and male patients with epilepsy were included Results: (32%) of the patients with epilepsy had unsatisfactory level of compliance to therapeutic regimen & followed instructions .Furthermore, the most common factors affecting patients` compliance negatively were therapy related factors, health care team, and financial burden (41.5%,39%&38.5%) respectively . Conclusion; more than two thirds of the patients with epilepsy had unsatisfactory compliance level.

The efficacy data of two household cleaning and disinfecting agents on Lens culinaris Medik and Vicia faba seed germination

A germination test of Vicia faba and Lens culinaris seeds under the effect of bleach and vinegar was conducted for seven days, and the observations were recorded daily. The completely randomized design (CRD) was used to examine the germination with three replicates at the lab conditions. Six germination parameters were measured, including germination percentage (GP), germination index (GI), mean germination time (MGT), mean germination rate (MGR), vigour index (VI), plus the fresh weight (FW) and dry weight (DW) of Vicia faba and Lens culinaris seeds. As a legume crop seeds model, the efficacy of four treatment levels from 0.005% to 0.5% of bleach and vinegar on the germination was tested. A chemical analysis was performed using the ion chromatography (IC) to evaluate the effect of chloride and acetate anions uptake on the seedling germination in addition to other essential nutrients. A significant inhibition in seedling growth was observed with increasing the treatment concentration. The maximum inhibition was recorded for both seeds at 0.5%, followed by 0.1% levels, while a positive effect was represented with the lower concentrations. The chemical analysis of the up taking active ingredients was corroborated the germination outputs

New methods of windowing for reducing the out of band emission with low complexity in the 5G waveform

Various 5G waveform candidates are used for wireless communication in multicarrier waveform design. This specifically includes Filtered-Orthogonal Frequency Division Multiplexing (F-OFDM) and Universal Filtered Multicarrier (UFMC) waveforms adopted in the high-speed 5G system and beyond. Previous literature studies showed that a high level for out of band emission (OOBE) and attaining accurate KPIs in real applications are the main obstacles in the 5G communication. Thus, the present study contributed in three new methods in the time domain, namely, Kaiser Hankel subband Window (KHW), hybrid window group subcarrier-windowing (HWG subcarrier windowing), and Convolution New Window type-windowing (CNW windowing) to suppress the value of OOBE in F-OFDM and UFMC and improve Power Spectral Density (PSD) without degradation of Bit Error Rate (BER) in the system. On the other hand, two methods were proposed in the frequency domain to decrease the OOBE while maintaining a low computational complexity, namely, Array window subcarrier windowing (AWsubcarrer-windowing) and the Half subcarrier edge windowing (HSE-windowing). The OOBE decrease for KHW, HWG, and CNW is 70%, 75%, and 80% for the ACLPRG for KHW, HWG, and CNW, respectively. Moreover, ACLPRG for AW and HSE is 78% and 81% of either the traditional in frequency domain approach. The merging also reduces suppression ACLPRG OOBE by 88%. Also, difficult real-addition and multiplication operations have been reduced by 33-45%. The new methods helped reduce the value of OOBE without affecting the system’s KPIs. The waveform could also coexist with a legacy system without affecting the core KPIs and key quality indicators (KQIs) by reduce the OOBE in the 5G waveform. Moreover, the study found that lowering OOBE did not increase system complexity. These findings have ramifications for academics, and 5G communication

Ibn 'Arabi's metaphysics of love: a textual study of chapter 178 of al-Futuhat al-Makkiya

This study examines the concept of Divine love and its various metaphysical articulations as enshrined in the thought of the Andalusian Sufi Ibn ‘Arabī (d. 1240 CE). In order to understand the concept of Divine love from the so-called “Akbarian” perspective, a thorough textual analysis of chapter 178, “On Knowing the Station of Love,” from Ibn ‘Arabī’s magnum opus, The Meccan Openings (al-Futūḥāt al-Makkiyya), will be carried out. This chapter, which is arguably the richest and most complex text on the topic of Divine love in the Sufi tradition, has not received detailed treatment in Western scholarship. The present study therefore aims to fill this lacunae, offering a complete reading and analysis of this work’s sophisticated cosmology, ontology, and psychology with reference to the development of love theory in the Sufi tradition which preceded Ibn ‘Arabī, and his own metaphysical worldview
