Partial Derivative Equations and Identities for Hermite-Based Peters-Type Simsek Polynomials and Their Applications
No full textThe objective of this paper is to investigate Hermite-based Peters-type Simsek polynomials with generating functions. By using generating function methods, we determine some of the properties of these polynomials. By applying the derivative operator to the generating functions of these polynomials, we also determine many of the identities and relations that encompass these polynomials and special numbers and polynomials. Moreover, using integral techniques, we obtain some formulas covering the Cauchy numbers, the Peters-type Simsek numbers and polynomials of the first kind, the two-variable Hermite polynomials, and the Hermite-based Peters-type Simsek polynomials

Topology of soft cone metric spaces
No full textInternational Conference on Functional Analysis in Interdisciplinary Applications (FAIA) -- OCT 02-05, 2017 -- Astana, KAZAKHSTANIn Simsek's paper it was introduced a concept of soft cone metric space via soft elements and some fixed point theorems in soft cone metric space were provided. In this work, we examine topological structures such as open ball, soft neighbourhood and soft open set in soft metric spaces and their some properties, and prove that every soft cone metric space under some condition is a soft topological space according to elementary operations on soft sets.Kyrgyz Turkish Manas University [KTMUBAP-2016.FBE.12]This work is supported by Kyrgyz Turkish Manas University in the framework of Scientific Research Projects (KTMUBAP-2016.FBE.12)
Migraine and Its Treatment from the Medicinal Chemistry Perspective
No full textMigraine is a disease of neurovascular origin that affects the quality of life of more than one billion people and ranks sixth among the most common diseases in the world. Migraine is characterized by a moderate or severe recurrent and throbbing headache, accompanied by nausea, vomiting, and photo-phonophobia. It usually starts in adolescence and is twice as common in women as in men. It is classified as with or without aura and has chronic or acute treatment types according to the frequency of occurrence. In acute treatment, analgesics that relieve pain in the fastest way are preferred, while there are different options in chronic treatment. While non-specific methods were used in the treatment of migraine until the 1950s, triptans, ditans, and CGRP-receptor-dependent therapies (monoclonal antibodies and gepants) started to be used in the clinic more recently. In this Review, we focus on the synthesis, side effects, and pharmacological and pharmacokinetic properties of FDA-approved drugs used in acute and preventive-specific treatment of migraine
pXRF study of pottery : State of the art and perspectives
No full textInternational audienceAlthough portable/handheld X-ray Fluorescence instruments are available from decades, the number of publications reporting on-site analyses of pottery remain very limited. Most of them present the paste composition and not the (glazed) décor. After a brief review of the published works about the studies of pottery and glass, we will discuss the advantages (on-site analysis and selection of artefacts, higher number of objects, better statistics …) and drawbacks (light elements and some traces not measured, difficulty to determine the analyzed volume, low quantity of informative elements…). We will take examples on three important series previously analyzed, 18th- century stonewares (from Meissen [1], Delft, China, England, France… belonging mainly to Sèvres collection, France), “Iznik” style tiles covering walls of Edirne mosques (Turkey World Unesco Heritage, Fig. 1 [2]) and Chinese and Vietnamese shards excavated from a medieval harbor (Qalhat, Oman Sultanate [3]) and discuss the two possible ways to extract information: i) the blind eyes approach using PCA and cluster variation statistical analysis, and ii) the comparison of particular element ratios or contents related to the raw materials used for the paste and the glaze (alkalis and earth alkalis, iron and titanium, lead, …) and the coloring and opacifying agents (tin, cobalt, copper, arsenic, nickel, manganese, …). Expected further developments will be discussed. [1] G. Simsek, F. Casadio, Ph. Colomban, K. Faber, L. Bellot-Gurlet, G. Zelleke, V. Milande, E.

Characterization of ‘Candidatus Phytoplasma solani’ associated with a maize leaf reddening disease in Turkey
No full textIn recent years, empty or poor grain bearing corn plants with leaf reddening symptoms have been observed in some commercial maize production areas in the Adana province of Turkey. The disease is increasing and causing economic losses. To verify the possible presence of phytoplasmas, leaf samples were tested with P1/Tint and R16F2n/R2 phytoplasma-specific primer pairs after DNA extraction. The 16S ribosomal gene sequence analysis followed by sequence in silico enzyme digestions and phylogenetic analyses allowed the identification of ‘Candidatus Phytoplasma solani’, subgroup of 16SrXII-A related-strain in all symptomatic samples. The positive samples were characterized using tuf and vmp1 genes. In silico restriction fragment length polymorphism and sequence analyses allowed the inclusion of all the positive samples into tuf-type b and V15 molecular types. The sequence analysis indicated the presence of a single genotype in all the tested samples (n = 12). This is the first molecular characterization of a ‘Ca. P. solani’ strain infecting maize plants in Turkey. The identified pathogen is listed in the EPPO A2 list
Il femminismo critico per re-immaginare una narrativa di genere nello sviluppo organizzativo
No full textIl contributo si sofferma sulla crescente ricerca sul Diversity management (DM) e le sue implicazioni per l’equità di genere, in particolare sul contesto italiano. Sebbene il DM sia riconosciuto come una scelta strategica vitale per le organizzazioni a livello globale, il suo sviluppo in Italia assume un focus predominante sulle questioni della forza lavoro femminile. Di fatto queste ultime, sebbene siano generalmente più istruite degli uomini, affrontano tassi di occupazione più bassi, che si restringono ulteriormente con l’aumentare del numero di figli e tendono ad avere un reddito più basso, data la precarietà dei loro contratti lavorativi, lo sbilanciamento di genere nei settori economici e la scarsa possibilità di ricoprire posizioni. Nel quadro teorico, il femminismo critico pone l’attenzione sullo smantellamento delle strutture organizzative patriarcali, enfatizzando la riflessione sul privilegio, la riforma strutturale per l’emancipazione, l’aumento della consapevolezza di genere e la ricostruzione della solidarietà. Allo stesso tempo, il costruzionismo sociale, radicato nella formulazione di rivendicazioni e nell’analisi narrativa, sottolinea la natura contestuale e interattiva dei problemi. Studi precedenti mettono in luce la necessità di una comprensione contestuale degli approcci di DM ed è in questo senso che la presente ricerca vuole contribuire. Lo studio utilizza la narrative inquiry per comprendere le perce-zioni di equità di genere nelle organizzazioni di Vicenza. 15 interviste semi-strutturate con i responsabili delle risorse umane e/o i rappresentanti sindacali esploreranno le politiche e le pratiche organizzative che promuovono l’equità di genere. Successivamente, tre digital storytelling workshop saranno organizzati con il personale delle organizzazioni che risulteranno virtuose, al fine di consentire loro di raccontare le loro esperienze. Questo sforzo mira ad esaminare e disseminare modelli organizzativi per migliorare l’equità di genere praticati dalle imprese di Vicenza. La ricerca vuole contribuire a sviluppare una maggiore consapevolezza e comprensione dell'equità di genere nelle organizzazioni di Vicenza e fornire spunti e strumenti per promuovere un cambiamento organizzativo positivo
