Scintillation Light Detection with MAPD-3NK and MPPC-S12572-010P Readout
The linearity and energy resolution of two different solid-state photomultipliers (SiPMs) has been studied with reading out the LFS-8 scintillator (3x3x10 mm3). First SiPM (MAPD-3NK) from Zecotek Photonics consists of deeply burned pixels (cells) and has an active area of 3.7x3.7 mm2. The second one (MPPC-S12572-010P) from Hamamatsu has a surface cell structure and an active area of 3x3 mm2. Both SiPMs have the same pixel density of 10000 mm−2. Energy resolution and linearity of the SiPMs has been studied in the energy range of 59.6-1275 keV. It is found that both SiPMs demonstrate good linearity of signal amplitude as a function of the gamma ray energy in the studied energy range. The detector based on the MAPD-3NK provides significantly good energy resolution in comparison to the detector based on the MPPC-S12572-010P

Real-world efficacy and safety of Ledipasvir plus Sofosbuvir and Ombitasvir/Paritaprevir/Ritonavir +/- Dasabuvir combination therapies for chronic hepatitis C: A Turkish experience
Background/Aims: This study aimed to evaluate the real-life efficacy and tolerability of direct-acting antiviral treatments for patients with chronic hepatitis C (CHC) with/without cirrhosis in the Turkish population.Material and Methods: A total of 4,352 patients with CHC from 36 different institutions in Turkey were enrolled. They received ledipasvir (LDV) and sofosbuvir (SOF)+/- ribavirin (RBV) ombitasvir/paritaprevir/ritonavir +/- dasabuvir (PrOD)+/- RBV for 12 or 24 weeks. Sustained virologic response (SVR) rates, factors affecting SVR, safety profile, and hepatocellular cancer (HCC) occurrence were analyzed.Results: SVR12 was achieved in 92.8% of the patients (4,040/4,352) according to intention-to-treat and in 98.3% of the patients (4,040/4,108) according to per-protocol analysis. The SVR12 rates were similar between the treatment regimens (97.2%-100%) and genotypes (95.6%-100%). Patients achieving SVR showed a significant decrease in the mean serum alanine transaminase (ALT) levels (50.90 +/- 54.60 U/L to 17.00 +/- 14.50 U/L) and model for end-stage liver disease (MELD) scores (7.51 +/- 4.54 to 7.32 +/- 3.40) (p<0.05). Of the patients, 2 were diagnosed with HCC during the treatment and 14 were diagnosed with HCC 37.0 +/- 16.0 weeks post-treatment. Higher initial MELD score (odds ratio [OR]: 1.92, 95% confidence interval [CI]: 1.22-2.38; p=0.023]), higher hepatitis C virus (HCV) RNA levels (OR: 1.44, 95% CI: 1.31-2.28; p=0.038), and higher serum ALT levels (OR: 1.38, 95% CI: 1.21-1.83; p=0.042) were associated with poor SVR12. The most common adverse events were fatigue (12.6%), pruritis (7.3%), increased serum ALT (4.7%) and bilirubin (3.8%) levels, and anemia (3.1%).Conclusion: LDV/SOF or PrOD +/- RBV were effective and tolerable treatments for patients with CHC and with or without advanced liver disease before and after liver transplantation. Although HCV eradication improves the liver function, there is a risk of developing HCC.Turkish Association for the Study of The Liver (TASL
Azerbaijan’s Foreign Policy Strategies and the European Union: Successful resistance and pursued influence
In recent years, Azerbaijan has positioned itself on the international scene as an increasingly important and assertive actor. This essay focuses on Azerbaijan’s relations with the European Union (EU). It will identify the policy strategies used by Azerbaijan to engage with the EU in two areas where their interests and objectives do not align, namely democracy and human rights promotion policies, and agenda-setting of the Nagorno-Karabakh conflict. The essay highlights, first, the relevance of national independence, ‘balancing’ and regime legitimacy in explaining Azerbaijan’s foreign policy strategies, and second, the mixed track record of Azerbaijan’s assertiveness, with different outcomes depending on whether the policy strategies are reactive or proactive
Steganography and new implementation of steganography [Steganografi ve steganografinin yeni bir uygulamasi]
IEEE 13th Signal Processing and Communications Applications Conference, SIU 2005 -- 16 May 2005 through 18 May 2005 -- Kayseri -- 69003This paper about steganography, a branch of cryptography, includes some problems and solutions about cryptography. Moreover, it involves a new algorithm definition which encryptes a document into any format of the picture. This algorithm takes advantages of asymmetric and symmetric crypto systems. © 2005 IEEE
Przygotowanie niedoprzędu lnianego do przędzenia w roztworze aktywowanym elektrochemicznie
A number of environmentally hazardous substances are used in the process of flax roving preparation for spinning. An alternative to them can be the use of electrochemical activated aqueous solutions. However, the metastability of such solutions requires time tracking of their properties’ relaxation. This article presents experimental data on the relaxation of relevant solutions that can be used for a well-founded selection of flax roving treatment procedures to ensure a required quality of flax yarn. It has been experimentally proven that the use of ECA solutions for preparing rovings for spinning allows to obtain high quality yarn as well as significantly reduce wastewater pollution and improve the environmental situation in the places of their emissions.W procesie przygotowywania przędzy lnianej do przędzenia stosuje się wiele niebezpiecznych dla środowiska substancji. Alternatywą dla nich może być zastosowanie elektrochemicznie aktywowanych roztworów wodnych. Jednak metastabilność takich roztworów wymaga śledzenia czasu relaksacji ich właściwości. W artykule przedstawiono dane eksperymentalne dotyczące roztworów. W celu zapewnienia wymaganej jakości przędzy lnianej uzyskane dane mogą znaleźć zastosowanie podczas wyboru procedur obróbki niedoprzędu. Udowodniono eksperymentalnie, że zastosowanie rozwiązań ECA do przygotowania niedoprzędów pozwala uzyskać przędzę wysokiej jakości, a także znacznie zmniejszyć zanieczyszczenie ścieków i poprawić sytuację środowiskową w miejscach ich emisji
