Lutheranism and Welfare State Expertise. The Example of Heikki Waris
Authors: Lindberg Hanna 
Published: October 2015

Abstract
The article examines the role of Christianity in the work of Heikki Waris (1901-1989), Professor of Social Policy at the University of Helsinki from 1948 to 1968. In studies on the historical foundations of different models of welfare, Lutheranism is often mentioned as a characteristic feature of the Nordic model. Previous research has, however, not to any larger extent examined the role of religion when analysing the work of so-called welfare experts. The article draws attention to importance of Christianity and the Lutheran Church, when analysing the work of a central architect of the Finnish welfare state. The article examines how Waris’ background within the Settlement movement influenced his later academic and social political work. Furthermore, it looks at how Waris dealt with religion, Christianity, the Lutheran Church and faith in his work on social policy and social change. The connection between social policy and Christianity is analysed more closely, both in Waris’ academic texts and the reports he wrote for the Lutheran Church on the challenges of the modern world.

Published: October 2015

Abstract
The time domain boundary element method was utilized to simulate the propagation of the irregular waves in a numerical wave tank. The problem was solved in a time-marching scheme, upon the irregular waves being fed through the inflow boundary, in which the theoretical solution was obtained from the wave energy spectrum. The open boundary condition was modeled by the multi transmitting formula (MTF), in which the phase velocity was calculated according to the Sommerfeld’s condition. The velocity potential and wave elevation were directly obtained by integrating the free surface condition twice, with respect to time. The accuracy of the developed numerical scheme was verified by simulating the propagation of irregular waves. The numerical results show good agreements with the analytical solutions, which prove that the proposed scheme is a promising way to the simulation of wave-body interactions.

Published: October 2015

Abstract
A theoretical model of acoustic field for a parametric focusing source on concave spherical surface is proposed. In this model, the source boundary conditions of the Spheroidal Beam Equation (SBE) for difference frequency wave excitation were studied. Propagation curves and beam patterns for difference frequency component of the acoustic field are compared with those obtained for Khokhlov-Zabolotskaya-Kuznetsov (KZK) model. The results demonstrate that the focused parametric model of SBE is good valid for a large aperture angle in the strongly focused acoustic field. It is also investigated that high directivity and good focal ability with the decreasing of downshift ratio and the increasing of half-aperture angle for the focused parametric model of SBE.

Authors: Li JunHua , Fan YanTing 
Published: October 2015

Abstract
The leakage from submarine pipe network is investigated by a numerical model in this paper. A whole event including of the steady flow before the leakage, the transient flow during the leakage and the steady flow after the leakage is considered in the model. The numerical results of the discharge and the head compare with the theoretical solution under the condition of steady flow. Good agreement is obtained. The numerical results of the discharge and the head show that the discharge and the head in each pipe changes suddenly after the leakage occurring. The abrupt trend of the discharge in each pipe is not same completely. Some change upwards, while others downwards. However, the abrupt trend of the head is always downward. The effects of leakage discharge on the transient flow are also investigated. It is founded that the larger the leakage discharge, the more obvious the abrupt trend of the discharge and the head before or after the leakage is.

Published: October 2015

Abstract
The Qingdong area, located in Bohai bay basin, was suspected good exploration prospects. In order to study tectonic features and find out favourable petroleum prospects in the area, the gravity data at a scale of 1:50,000 were interpreted. This paper, through data processing and synthetic interpretation of the high-precision gravity data in the area, discusses characteristics of the gravity field and their geological implications, determines the fault system, analyses features of the main strata, divides structure units and predicts favourable petroleum zones. The results showed that the faults controlled the development of the Mesozoic and Cenozoic strata and the distribution of local structures in this area. The study revealed that the Qingtuozi uplift and the Kendong uplift in the north were formed in Mesozoic, and the Qingdong depression in the middle was the rift basin in Mesozoic and Cenozoic. Thicker strata in Mesozoic and Cenozoic developed in the Dongying depression and the Qingdong depression, so there is abundant hydrocarbon in these two depressions, and then the Guangligang rise-in-sag and the Qingdong rise-in-sag developed in the center in these two depressions are also favorable places for prospecting

Published: October 2015

Abstract
Zinc fuel is considered as a kind of promising energy sources for marine propeller. As one of the key steps for zinc marine energy power system, zinc hydrolysis process had been studied experimentally in a fixed bed reactor. In this study, we focus on the characteristics of micron zinc particle hydrolysis. The experimental results suggested that the steam inner diffusion is the controlling step of accumulative zinc particles hydrolysis reaction at a relative lower temperature and a relative higher water partial pressure. In other conditions, the chemical reaction kinetics was the controlling step. And two kinds of chemical reaction kinetics appeared in experiments: the surface reaction and the gas-gas reaction. The latter one occurs usually for larger zinc particles and high reaction temperature. Temperature seems to be one of the most important parameters for the dividing of different reaction mechanisms. Several parameters of the hydrolysis process including heating rate, water partial pressure, the particle size and temperature were also studied in this paper. Results show that the initial reaction temperature of zinc hydrolysis in fixed bed is about 410°C. And the initial reaction temperature increases as the heating rate increases and as the water partial pressure decreases. The total hydrogen yield increases as the heating rate decreases, as the water partial pressure increases, as the zinc particle size decreases, and as the reaction temperature increases. A hydrogen yield of more than 81.5% was obtained in the fixed bed experiments.

Published: October 2015

Abstract
This paper conducts calibration tests on the shallow-water maneuverability of 1:100 ship models for the typical navigation fleets in Three Gorges Reservoir. Major influential factors for the maneuverability similitude between models and prototypes and for scale effect were identified. A correction method for model scale was also established through model tests. Test results indicate that, by correcting the model scales of various fleets based on scale effect, the maneuverability indexes K’ (dimensionless of K) and T’ (dimensionless of T) of ship models are suitable for shallow-water tests, and properly reflect the maneuvering characteristics of prototypes. The findings provide an experimental basis for the navigation safety in Three Gorges Reservoir.

Abstract
The travel time tomography technology had achieved wide application, the hinge of tomography was inversion algorithm, the ray path tracing technology had a great impact on the inversion results. In order to improve the SNR of inversion image, comprehensive utilization of inversion results with different ray tracing can be used.

Therefore, the ill-conditioned linear equations were changed into iterative normal system through two times of treatment and using images with different forward algorithms for image fusion, it reduced the influence effect of measurement error on imaging. Simulation results showed that, this method can eliminate the artifacts in images effectively, it had extensive practical significance.

Published: October 2015

Abstract
With the development of automation in ports, the video surveillance systems with automated human detection begun to be applied in open-air handling operation areas for safety and security. The accuracy of traditional human detection based on the video camera is not high enough to meet the requirements of operation surveillance. One of the key reasons is that Histograms of Oriented Gradients (HOG) features of the human body will show great different between front & back standing (F&B) and side standing (Side) human body. Therefore, the final training for classifier will only gain a few useful specific features which have contribution to classification and are insufficient to support effective classification, while using the HOG features directly extracted by the samples from different human postures. This paper proposes a two-stage classification method to improve the accuracy of human detection. In the first stage, during preprocessing classification, images is mainly divided into possible F&B human body and not F&B human body, and then they were put into the second-stage classification among side human and non-human recognition. The experimental results in Tianjin port show that the two-stage classifier can improve the classification accuracy of human detection obviously.
Celestial Navigation Fix Based on Particle Swarm Optimization
Authors: Tsou Ming-Cheng 
Published: October 2015

Abstract
A technique for solving celestial fix problems is proposed in this study. This method is based on Particle Swarm Optimization from the field of swarm intelligence, utilizing its superior optimization and searching abilities to obtain the most probable astronomical vessel position. In addition to being applicable to two-body fix, multi-body fix, and high-altitude observation problems, it is also less reliant on the initial dead reckoning position. Moreover, by introducing spatial data processing and display functions in a Geographical Information System, calculation results and chart work used in Circle of Position graphical positioning can both be integrated. As a result, in addition to avoiding tedious and complicated computational and graphical procedures, this work has more flexibility and is more robust when compared to other analytical approaches.
Influence of Pitting Corrosion on Fatigue and Corrosion Fatigue of Ship and Offshore Structures, Part II: Load - Pit - Crack Interaction
Authors: Jakubowski Marek 
Published: October 2015

Abstract
In the paper has been discussed influence of stresses on general corrosion rate and corrosion pit nucleation rate and growth , whose presence has been questioned by some authors but accepted by most of them. Influence of roughness of pit walls on fatigue life of a plate suffering pit corrosion and presence of the so called „ non-damaging” pits which never lead to initiation of fatigue crack, has been presented. Possibility of prediction of pit-to-crack transition moment by two different ways, i.e. considering a pit a stress concentrator or an equivalent crack, has been analyzed. Also, influence of statistical distribution of depth of corrosion pits as well as anticorrosion protection on fatigue and corrosion fatigue has been described.
Comparing Guidelines Concerning Construction of the S-N Curve within Limited Fatigue Life Range
Authors: Strzelecki Przemysław , Sempruch Janusz , Nowicki Krzysztof 
Published: October 2015

Abstract
The article collates guidelines concerning experimental construction of the S-N fatigue curves within a limited fatigue life range. An attempt is made to compare these guidelines, based on experimental data recorded during rotating bending of a notched specimen made of 42CrMo4. The recorded differences in fatigue life values between the constructed curves reach the maximum of 12.2%. According to the above guidelines, the number of tests in particular test series varies from 6 to 28. Based on the performed analysis a conclusion was made that the increase in the number of tests leads to the increase of accuracy but, on the other hand, remarkably increases the time of the experiment and, consequently, its cost. In this context, it is the research worker who, taking into account a possible future use of the fatigue curve, should individually decide about its accuracy.
Laser Doppler Vibrometer Based Examination of the Efficiency of Introducing Artificial Delaminations into Composite Shells
Authors: Kustroń Kamila 
Published: October 2015

Abstract
During its operation, the laminate shell of the watercraft hull can be exposed to local stability losses caused by the appearance and development of delaminations. The sources of these delaminations are discontinuities, created both in the production process and as a result of bumps of foreign bodies into the hull in operation. In the environment of fatigue loads acting on the hull, the delaminations propagate and lead to the loss of load capacity of the hull structure. There is a need to improve diagnostic systems used in Structural Health Monitoring (SHM) of laminate hull elements to detect and monitor the development of the delaminations. Effective diagnostic systems used for delamination assessment base on expert systems. Along with other tools, the expert diagnostic advisory systems make use of the non-destructive examination method which consists in generating elastic waves in the hull shell structure and observing their changes by comparing the recorded signal with damage patterns collected in the expert system database. This system requires introducing certain patterns to its knowledge base, based on the results of experimental examinations performed on specimens with implemented artificial delaminations. The article presents the results of the examination oriented on assessing the delaminations artificially generated in the structure of glass- and carbon-epoxy laminates by introducing local non-adhesive layers with the aid of thin polyethylene film, teflon insert, or thin layer of polyvinyl alcohol. The efficiency of each method was assessed using laser vibrometry. The effect of the depth of delamination position in the laminate on the efficiency of the applied method is documented as well.

Authors: Xu Xiao-Yan , Mindykowski Janusz , Tarasiuk Tomasz , Cheng Chen 
Published: October 2015

Abstract
An improved harmonic detection method based on average arithmetic is proposed. According to the research results, the designed solution uses an LPF (low-pass-filter) and a mean value module connected in series instead of the conventional mean value module, and simultaneously, a three-phase voltage phase-locked module instead of commonly used PLL (phase lock loop) module is applied in order to reduce the influence caused by three-phase distorted voltage and rapid variation of load. The experimental results show that the application of this solution leads to increase in the accuracy of harmonics detection for distorted three-phase voltage and rapid variation of load.

Published: October 2015

Abstract

Diabetic Nephropathy. In 2014 (according to data published by the World Health Organization) 9% of the global population was affected by Diabetes which was considered to be directly responsible for 1.5 million deaths just two years prior (in 2012). From the entire number of patients suffering from diabetes, approximately a quarter of them develop renal affection. Diabetic nephropathy has similar physiopathology mechanisms and ultrastructural changes in cell injury characteristics in both Type 1 and Type 2 diabetes.

Cell Death. Cell Death was less studied in the renal diabetic disease, although it could represent an important pathogenic mechanism in the appearance and progression of nephropathy. At renal level the cellular loss can be explained by several mechanisms; different stimuli with cellular lesion potential can trigger apoptosis signaling with appearance of regulatory proteins having a double role (they participate in the initiation of the apoptosis path and cell death or in the ending of this process). The types of Cell Death and their relative proportion between themselves in the renal tissue have not been completely elucidated.

Caspases. Discovered in the middle of the 1990’s, Caspases are a part of the cysteine proteases family and play a role in numerous aspects of physiology (having a role in development, aging and apoptosis), but also in aspects of physiopathology of several degenerative affections, autoimmune diseases, oncologic diseases – having an important part in apoptosis, necrosis and also inflammation.
Liver Fibrosis: Causes and Methods of Assessment, A Review
Authors: Karimzadeh Toosi Ali Erfani 
Published: October 2015

Abstract
Hepatic fibrogenesis is the final result of injury to the liver. Fibrosis could lead to hepatic dysfunction, important in the pathogenesis of other chronic problems. Therefore, understanding the mechanism, accurate diagnosis and staging of it in early stages accelerates the treatment and reduces the prevalence of chirrosis. Treatment strategies of liver problems and detction methods depend on the amount and progression of liver fibrosis and the rate of cirrhosis development. Traditionally the invasive method, liver biopsy, is reference standard to follow progression and stage of fibrosis. However, during the past decade, progressive development of novel non-invasive methodologies has challenged the invasive method. Non-invasive methods have been initially introduced for chronic hepatitis C with increasing use in other chronic liver diseases. The need for liver biopsy has nowadays decreased significantly as a result of these methodologies. Most of the new non-invasive methods depend on either ‘biological’ or ‘physical’ approaches.
In this review, starting from the mechanism of fibrogenesis, the current knowledge about diagnosis, treatment strategies and different methods for its evaluation is discussed. This is followed by a conclusion on what is expected to be known in this field during the future research.

Abstract

Introduction. Mild cognitive impairment (MCI) is the prodromal stage of Alzheimer’s disease (AD), so identification of the related risk factors can be helpful. There are controversial data regarding the serum oxidant/antioxidant status, trace elements and homocysteine (Hcy) as effective parameters in this disease, therefore the status of these factors was determined in this study.

Methods. One hundred-twenty elderly persons with cognitive impairment and 120 elderly healthy persons who were differentiated using Mini-mental state examination (MMSE) participated in this study. The patients were divided into mild and moderate-to-severe cognitive impairment group. Serum antioxidant/oxidant, copper (Cu), manganese (Mn), zinc (Zn) and Hcy concentrations were measured using routine methods.

Results. Oxidant and antioxidant levels increased and decreased based on the severity of the disease and were higher and lower in patients than in control group, respectively (p<0.001). With adjusting for age, gender and education, significant difference in Hcy levels was not observed. There was no significant difference in trace elements levels among groups.

Conclusions. Results confirmed the association between oxidative damage with increasing the severity of cognitive impairment. These factors may be involved in the etiology of cognitive impairment and AD. Identification of such biomarkers is important to select appropriate treatment goals before the onset of irreversible clinical signs.
Eosinophilia and Hypereosinophilic Disorders – Update on Etiopathogeny, Classification and Clinical Approach
Authors: Leru Polliana Mihaela 
Published: October 2015

Abstract
Eosinophils are innate immune leukocytes recruited in large numbers to sites of allergic inflammation and parasitic infections. Recent studies show additional pleiotropic effects of recruited eosinophils impacting immunomodulation, tissue homeostasis and repair. Pathologic conditions accompanied by blood eosinophilia are quite frequent in medical practice and may raise serious differential diagnosis problems in severe cases, that require a multidisciplinary approach. Hypereosinophilia may be reactive to other diseases or primary, representing hypereosinophilic syndromes, that are diagnosed based on clinical and laboratory criteria, according to actual international guidelines. The etiopathogenic diagnosis is difficult and delayed in many cases and clinical evolution may be severe, with multiorgan involvement and poor prognosis. Some cases remain idiopathic, despite exhaustive investigation. This paper aims to review the most recent data in the literature referring to the role of eosinophils in human pathology, diagnostic criteria and treatment strategies of hypereosinophilic syndromes, actual classification and to draw some useful recommendations in clinical practice.
Experimental and numerical investigation of non-submerged flow under a sluice gate
Authors: Kiczko Adam , Kubrak Janusz , Kubrak Elżbieta 
Published: October 2015

Abstract
The problem of sluice gate flow is analyzed using two models: a simplified one, derived according to the concept of the Potential Field (PF), and a more complex form, based on the Reynolds Average Navier-Stokes (RANS) equations. The numerical solution is compared with experimental data, including measurements performed by authors and results acquired from literature. Despite its simplicity, the PF model provides a satisfactory agreement with the measurements. The slightly worse performance of the RANS model comes from an overestimation of energy losses.
