Abstract
Protective coatings can be used to enhance the performance of interconnects in solid oxide fuel cells. In the present work, AISI 304 steel was coated with Ni–Fe2O3 composite from a modified Watt's type electrolyte by electroplating. The composite coating's microstructure and composition were investigated by scanning electron microscopy with energy dispersive X-ray spectroscopy and X-ray diffraction. Isothermal oxidation for 200 h in air at 850 °C converted the Ni–Fe2O3 composite coating to Fe2O3/NiFe2O4. The coating layer also decreased outward migration of chromium and the growth rate of a Cr2O3 layer, compared to an uncoated specimen.

Abstract
Cu0.5FeNiVAl
x
high entropy alloys have been designed and prepared to study the microstructure and mechanical properties in as-cast and heat treated states. The as-cast Cu0.5FeNiV alloy is mainly composed of fcc and σ phases. With the increase in Al, the phase composition gradually changes to the fcc + bcc structure. In the Cu0.5FeNiVAl
x
alloy system, the compressive strength (1 801 MPa) of Cu0.5FeNiVAl0.5 alloy is the best, and the Cu0.5FeNiVAl1.2 alloy has the highest hardness (694 HV). In order to improve its strength, the Cu0.5FeNiVAl0.5 alloy was annealed at 500 °C, 750 °C and 1 000 °C for 10 h, respectively. The highest compressive strength (2 154 MPa, increased by 20 % compared to the as-cast state) is reached at 750 °C annealing temperature. Meanwhile, the microhardness is increased from 516 HV to 670 HV, an increase of 30 % relative to the as-cast one. Study of the heat treatment process on the mechanical properties of high-entropy alloys contributes to the transformation of these materials from the laboratory research stage to the practical production stage.

Authors: Bode Rovena , Braholli Eriol , Haxhiu Asfloral , Draçini Xheladin , Çeliku Etmont 
Published: January 2019

Background: Caecal diverticulitis is an unusual condition that presents clinically similar to appendicitis. The diagnosis is not always easy and in the majority of cases, it is usually made at laparotomy. The aim of the present study is to retrospectively report our personal experience with solitary caecal diverticulitis, to determine its incidence in patients presenting as an acute abdomen, as well as identify the symptoms and clinical features that may aid in making a pre-operative diagnosis. And to compare this with a review of the literature, focusing on the surgical treatment and also on the indication of appendectomy in the presence of caecal diverticulitis not requiring surgery.
Materials and methods: Data was collected in patients hospitalized for acute appendicitis or acute abdomen, in the surgical emergency unit of University Hospital Center "Mother Teresa" of Tirana, in a period of 3 years (2015-2017). Sex, age, duration of symptoms, preoperative diagnosis, management, intraoperative findings, histologic examination, length of hospital stay and complications of allpatients affected by solitary caecal diverticulitis were reviewed.
Results: In the study period, 15 patients presented with a solitary caecal diverticulitis. Most of patients had pain in the right iliac fossa, with a duration of 2–6 days. All patients presented with abdominal pain, additional symptoms were nausea, vomiting and fever. The mean white blood cell count was from 8500-19.200/mm3, while the remaining laboratory results were normal. There were no specific findings on abdominal X-ray or ultrasonography. Intraoperative findings ranged from localized /circumscript peritonitis to generalised peritonitis due to acute diverticulitis and a normal appendix. Surgery ranged from diverticulum resection accompanied to appendectomy, to ileocaecal resection, and right hemicolectomy.
Conclusions: Cecal diverticulitis should be included in the differen­tial diagnosis of the cases with pain in the right lower quadrant. Preoperative diagnosis of caecal diverticulitis cannot always be made, since the signs and symptoms are similar to acute appendicitis, but is impor­tant in order to decide how to manage this condition.Diverticulectomy and incidental appendectomy are the preferred method of treatment in uncomplicated cases. Right hemicolectomy is a recommended treatment option in complicated patients or those suspicious for tumor during surgery.

PERFORMANCE ANALYSIS FOR DIRECTION-FINDING CIRCULAR ANTENNA ARRAY
Authors: Ballandovich Svyatoslav V. , Kostikov Grigory A. , Liubina Liubov M. , Sugak Mikhail I. 
Published: January 2019

This paper considers circular antenna arrays comprised of symmetrical dipole radiators applied in communication, navigation and monitoring systems. Despite their widespread use, a number of significant issues is underinvestigated. Among them are frequency dependence of the antenna factor (the ratio of the electric field intensity module to the voltage amplitude at the load connected to the output terminals) of the circular antenna array elements in the correct electrodynamic setting. The purpose of this paper is to analyse the antenna factor frequency dependence of a single dipole antenna with different geometry and load both in free space and as circular antenna element. The estimation of phase difference error between the circular antenna array elements caused by their cross coupling is also of interest.Specific expressions are obtained for the antenna factor of the dipole antenna for single-mode and three-mode approximations. The limits of their applicability in frequency band are considered. The solution to the coupled integral equations is obtained using the Galerkin method with piecewise sinusoidal current distribution and with an arbitrary number of basis functions for eight- and four-element circular antenna array. This solution may be generalized to an arbitrary number of circular antenna array elements. It is demonstrated that to improve the antenna factor frequency dependence it is advisable to use dipole antennas with high-resistance load, as well as with large diameter. Phase errors for different circular antenna array element signals are considered with respect to the reference element. The dependence of these phase errors on the circular antenna array geometry is presented. It is concluded that there are significant oscillations of the antenna factor when the dipole is the part of the circular antenna array. They are caused by cross coupling between the circular antenna array elements, which significantly depend on the element spacing. The results presented may be of interest to phase direction finder development engineers.

Published: January 2019

The study object is the search procedure for a ground-based radionavigation system signal using noise-like discrete signals with a long baseline. A comparative analysis of the signal search quality indicators is carried out, which is the most time-consuming procedure with different navigation signal modulation formats in the worst-case conditions and with a limited frequency resource allocated to the system. Bandwidth efficiency of noise-like signals (NLS) with phase shift keying (PSK) and minimal frequency shift keying (MFSK) are analyzed. Relations are obtained for the average maximum search time of the navigation signal with a fixed probability of correct search completion. The qualitative indicators of the search procedure for PSK and MFSK are compared for the same band pass effectiveness and elementary symbol duration. The analysis results show that under the conditions of equal restrictions on the occupied frequency range and the same requirements for the search procedure reliability, NLS MFSK search is effective and implementable at much lower time costs than NLS with traditional binary PSK.
