Abstract
The aim of the study was to determine the impact the surgical implantation of acoustic transmitters (AT; implantation incisions were sutured with tissue adhesive) had on the condition and health of pikeperch, Sander lucioperca (L.), (initial body weight of approximately 600 g). After tagging, the fish were held for 42 days in recirculating aquaculture systems. During this period, no negative effects were observed stemming from the implantation of AT on fish growth, condition, survival, or foraging effectiveness. The procedure also did not have a negative impact on hematological indicators. Among the 13 biochemical blood plasma indicators analyzed, only glucose level in the fish tagged with AT was significantly lower than that in the control group (P≤0.05). The rate of wound healing and the condition of the implantation incisions raised no concerns. Three weeks following the AT implantation procedure the incisions were closed and no infection was noted. Short-term AT retention (42 days) was 83.3%, and the fish shed the tags in the first two weeks following implantation.

Published: November 2018

Abstract
The optimal control of moving boundary problems receives growing attention in science and technology. We consider the so called two-phase Stefan problem that models a solid and a liquid phase separated by a moving interface. The Stefan problem is coupled with incompressible Navier{Stokes equations. We take a sharp interface model approach and define a quadratic tracking-type cost functional that penalizes the deviation of the interface from the desired state and the control costs. With the formal Lagrange approach and an adjoint system we derive the gradient of the cost functional. The derived formulations can be used to achieve a desired interface position. Among others, we address how to handle the weak discontinuity of the temperature along the interface with mesh movement methods in a finite element framework.

Abstract
The problem of crack propagation in human bone is studied. We for- mulate and solve the mathematical problem for the pre-stressed crack in Mode I of classical fracture. Using the boundary conditions on the crack faces in the bone, regarded as an elastic composite material, we solve our Riemann-Hilbert problem. Using generalized Sih's strain energy density generalized and maximum stress criteria we find the direction of the crack path in Iliac bone, regarded as a pre-stressed orthotropic composite.

Abstract
Polycystic Ovary Syndrome (PCOS) is characterized by hyperandrogenism, amenorrhea, and polycystic ovaries. This endocrinopathy is associated with many metabolic disorders such as dyslipidemia and insulin resistance, with increased risk of type 2 diabetes mellitus, metabolic syndrome, and cardiovascular complications. Inflammation is likely to play an important role in the promoting these metabolic imbalances, while prothrombotic and pro-oxidative mechanisms further contribute to the cardiovascular risk of these patients. The etiology of PCOS is still not fully understood, but there is evidence of genetic and environmental components. This review aims to discuss some molecular pathways associated with PCOS that could contribute to the better understanding about this syndrome. Recent evidence suggests that intrauterine exposure of female mice to an excess of anti-Müllerian hormone may induce PCOS features in their post-natal life. High cytokine levels and cytokine gene polymorphisms also appear to be associated with the pathophysiology of PCOS. Furthermore, high levels of microparticles may contribute to the altered hemostasis and enhanced inflammation in PCOS. All these mechanisms may be relevant to clarify some aspects of PCOS pathogenesis and inspire new strategies to prevent the syndrome as well as treat its symptoms and mitigate the risk of long-term complications.
Continuity and Extinction of Agricultural Land in the Sudetes - A Case Study in the Landscape of Highlands and Mountains
Authors: Zelinka Vít 
Published: November 2018

Abstract
The Sudetenland has undergone a dramatic development in Czechia. Above all, the frontier regions of the then Czechoslovakia lost due to the decision on the displacement of the Sudeten Germans in 1945 almost 3 million native inhabitants, who left their settlement areas in several waves by 1947. This change affected up to 3 million hectares of agricultural land that became the state property. This had in many places eliminated the traditional way of farming and the disruption of ownership relations consequently led to the breaking of relations in the landscape. This case study focuses on the comparison of the development of the agricultural landscape of 4 selected cadastral areas on the border of Krkonoše and Jizera Mountains from the post-war period to the present. Selected areas of interest are pairs of comparable cadastres from areas affected by the displacement of the local German population and areas with a permanent population structure. This four sites covering a total area of 4052 ha were studied in Cool Landscape of Highlands and the Moderately Cold Landscape of Mountains. Historical and contemporary land-cover information was provided by aerial photographic images from 1953/1954 and aerial orto-photos from 1998 and 2015/2016. The results have shown that on all four of the areas there was a noticeable increase in forests on former agricultural land. However, the monitored areas differ in the continuity of agricultural land. Continuous agricultural land represents, in both areas affected by post-war displacement, approximately 55 % of the original agricultural land. Areas with a well-preserved population structure, on the other hand, show an overall continuity of agricultural land on about 71 % of the former area of agricultural land.
Performance and Stability Analysis of Series-Cascaded, High-Gain, Interleaved Boost Converter for Photovoltaic Applications
Authors: Kumar C. Prasanna , Venugopal N. 
Published: November 2018

Abstract
Interleaved boost converters (IBCs) are cascaded in parallel in most of the applications. This novel approach connects IBC in series cascade. The IBC has an optimal operating duty cycle of 0.5. Normally, photovoltaic source voltage is low because of space constraints. In order to boost the source voltage, a conventional boost converter is replaced with series-cascaded IBC in this paper. The single-stage IBC also boosts the voltage to twice the input voltage. In the proposed converter, output voltage is about four times the input voltage with the same 0.5 duty cycle. A mathematical model is developed and simulated for the proposed work in MATLAB/Simulink platform. The output of the proposed circuit is analysed through fast Fourier transform to know the harmonic content due to the switching. The system is tested for stability with signal-flow graph modelling. The proposed work is realised using hardware and tested to validate the model.

Perubahan fluktuasi frekuensi sangat mempengaruhi kualitas daya pada sumber energi terbarukan turbin angin yang dihibrid dengan diesel. Sistem hibrid adalah jaringan terkontrol dari beberapa pembangkit tenaga energi terbaharukan seperti : turbin angin, sel surya, mikrohidro dan sebagainya. Ada beberapa permasalahan yang dapat meningkatkan osilasi frekuensi rendah, seperti tidak optimalnya setting gain dan kecilnya waktu konstan pada Automatic Voltage Regulator, Terlalu banyak jaringan transmisi yang panjang sehingga kemampuan lemah (weak line). Dalam penerapannya sistem wind-diesel dikontrol dengan kontroler PID, namun dalam penyetelan nilai gain dari PID masih dalam metode trial-error saja, sehingga sulit untuk mendapatkan nilai optimum dari PID. Dalam penelitian ini diterapkan desain kontrol dengan menggunakan Metode Cerdas dalam mencari nilai optimum Proporsional Intergral Derivatif (PID) untuk mengatur frekuensi beban dengan program Matlab/ Simulink. Pemodelan wind-diesel menggunakan fungsi transfer dari diagram turbin angin dan diesel. Respon sistem dengan Simulink/ Matlab dengan membandingkan dengan sistem tak terkontrol dan dengan metode PID-Trial Error, menunjukkan bahwa besar overshoot dan respon keadaan mantap (Settling Time) pada sistem terkontrol Differential Evolution (DEVO) menjadi berkurang dan lebih cepat.AbstractChanges in load frequency greatly affect the power quality of renewable wind turbine energy sources with diesel. Hybrid power system is a network consisting of several renewable energy plants such as wind power, solar power, hydro power, and others. Some problems can increase the low frequency oscillations in the system, such as gain settings and small time constants of the non-optimal Automatic Voltage Regulator, long transmission lines so that their capabilities are weak (weak line). In some previous studies, the wind-diesel system is controlled by conventional Proportional, Integral, Derivative (PID) controllers, but the PID gain setting is still in the trial-error method, making it difficult to obtain optimal PID values. In this research, we proposed a method of optimizing PID parameters in wind-diesel by using intelligent method based on Differential Evolution (DEVO). The objective function of this research is to minimize Time Absolute Error (ITAE), so that the overshoot will be muted properly. Wind-diesel modeling uses the diagram of the transfer function of wind-diesel. From the analysis results obtained optimal PID parameters respectively, Kp = 79.9999, Ki = 59.9998, Kd = 9.9006. The smallest resulting overshoot is -7.932e-05 to 6.792e-10 pu where the smallest overshoot value is compared to other controller models. The frequency response obtained by optimal PID tuning will dampen the frequency oscillation due to load changes, indicated by small overshoot and fast settling time to steady state conditions.
