Authors: Rif'an Ahmad , Hidayat Taufiq , Winarso Rochmad 
Published: January 2019

Aluminium memiliki rasio kekuatan terhadap massa yang paling tinggi, sehingga banyak digunakan sebagai bahan komponen mesin, misalkan gesekan yang terjadi pada piston rem yang merupakan komponen penggerak dari sistem kerja rem hidrolis. Akibat dari kerja komponen tersebut maka akan timbul adanya pengikisan permukaan komponen.Tujuan penelitian ini adalah untuk mengetahui fenomena keausan alumunium 6020 alloy dengan menggunakan metode pengujian two disk tribometer, yang dilakukan dengan pelumasan dan tanpa pelumasan pada pembebanan 10 kg dengan kecepatan putaran 1000 rpm, dan waktu 60 menit, setiap 10 menit dilakukan pengukuran keausan pada spesimen.Hasil pengujian keausan pada spesimen yang terbuat dari material aluminium 6020 alloy dengan menggunakan pelumasan SAE 10W-30 dan tanpa pelumasan memperoleh kesimpulan bahwa setiap menit keausan pada disk meningkat, keausan dengan pelumasan mempengaruhi laju keausan pada spesimen uji dengan nilai rata-rata laju keausannya sebesar 0,000466 mm3/N.m, sedangkan rata-rata laju keausan pada tanpa pelumasan sebesar 0,000784 mm3/N.m. Laju keausan tanpa pelumasan lebih besar dari laju keausan dengan menggunakan pelumasan.

Derechos de la naturaleza y justicia ecológica intergeneracional
Authors: Lamberti Alicia Morales 
Published: January 2019

El reconocimiento de la función ambiental de los derechos en el ámbito del paradigma de la justicia ambiental intergeneracional, se ha visto influenciado progresivamente por la coexistencia de otro paradigma no necesariamente excluyente de aquél, basado en el reconocimiento de valores intrínsecos y derechos de la naturaleza, en el marco de una justicia ecológica intergeneracional.
Los derechos intergeneracionales y el reconocimiento de los derechos de la naturaleza, emancipada de su consideración como objeto (bien jurídico) y reconocida como sujeto de derechos, se presentan como derechos de cuarta y quinta generación que cuestionan las prevalentes concepciones antropocéntricas del derecho ambiental.
En ese marco, el análisis se centra en el progresivo reconocimiento normativo y jurisprudencial en numerosos países, de los valores intrínsecos y derechos de la naturaleza en el marco de una justicia ecológica intergeneracional, interpela acerca de los nuevos paradigmas que distinguen a actuales debates jurídicos y políticos, en torno a la relación entre los derechos humanos y el medio ambiente.

El libro Cambio Climático y Emisiones Históricas. surge como fruto del proyecto de investigación ‘Justicia climática. El significado de las emisiones históricas’ llevado a cabo en la Universidad de Graz entre los años 2010 y 2013. Es fruto también de los últimos años de intenso y concienzudo trabajo de sus editores, Lukas Meyer y Pranay Sanklecha. El libro recoge la investigación novedosa de algunos de los mejores investigadores en justicia climática de diferentes universidades del mundo. Todos ellos comparten la hipótesis que da sentido conjunto al texto, a saber: que el cambio climático debe ser analizado desde el punto de vista de la justicia intergeneracional en sus diferentes dimensiones temporales. Por ello, la justicia climática debe comprender una reflexión tanto sobre las emisiones futuras permisibles, como sobre significado moral de las emisiones del pasado. Uno de los debates más importantes y extendidos en el campo de la justicia climática es el de la distribución justa de las cargas asociadas al cambio climático. El debate gira en torno a tres diferentes principios morales como el principio de ‘los contaminadores pagan’ (PCP), el principio de ‘los beneficiarios pagan’ (PBP) y el principio moral de ‘los que tienen recursos pagan’ (PRP). El libro que aquí presento cuenta con diferentes capítulos que ejemplifican este debate, aún vivo, entre los defensores de diferentes principios y sus detractores.

Abstract
The aim of the paper was to determine the efficacy, toxicity and progression free survival with anti-PD-1 immunotherapy pembrolizumab in BRAF wild type metastatic melanoma patients with good performance status (ECOG PS 0-1). From February 2017 to April 2018, 17 patients with BRAF mutant wild type metastatic melanoma were enrolled in the study. Only 3/17 patient had received chemotherapy previously. The aim of the study was to confirm the efficacy of pembrolizumab immunotherapy in patients with good performance status (ECOG 0-1). Treatment consisted of pembrolizumab 2 mg/kg Q3 weeks continued until disease progression or intolerable toxicity. Secondary end points included toxicity and progression-free survival (defined as the time from randomization to documented disease progression according to RECIST). The overall response rate (ORR) was 11/17 (53.0 %), with complete response (CR) 0, partial response (PR) 3 (18 %), stable disease (SD) 8 (47%), and progressive disease (PD) 6 (35%). A total number of 97 consecutive cycles were administered. Adverse effects were mild. The most common toxicity was pneumonitis grade 1. None of the patients in the study demonstrated grade 2, 3 and 4 toxicity. No treatment-related deaths occurred. The median time to disease progression was 5.8 months. Anti-PD-1 pembrolizumab immunotherapy appeared to be a beneficial therapeutic approach with less toxicity for metastatic BRAF wild type melanoma patients with good PS.

Abstract
Congenital brachial palsy (CBP) can have long-term consequences such as deformities, contractures and growth imbalance of the affected arm and shoulder girdle that can lead to severe handicap. The aim of the paper was to determine the effectiveness of early habilitation in infants with CBP. This retrospective clinical study included 34 infants who were habilitated in the Physical Medicine and Rehabilitation Clinic, Clinical Center Niš, during the period from 2000 to 2017. The protocol consisted of passive and active-assisted range of motion exercises for the affected arm, neurodevelopmental treatment, warm packs and electrotherapy, starting from the 3rd week of life. At the Clinic, 20 sessions were conducted and parents were educated with handling and home exercise program. The infants were re-evaluated each month during the first year of life. The modification of the manual muscle test (MMT) was used to assess the muscle strength (grades 0- 3). At 6 and 12 months of age, the outcome was defined as a full recovery (grade 3 of the affected muscles) and partial recovery (grades 1-2). Male sex predominated (56%). The right arm was more commonly affected (65%). Birth weight was over 4000g in 65% of infants. Fifty-nine percent of infants had upper, 26.5% "extended" and 14.5% had complete root palsy. Associated injuries were noted in 10 infants. The habilitation started in the first month of life in 64.7% of infants. At 6 months of age, full recovery was achieved only in one infant, while at 12 months, 56% of infants were fully recovered (p < 0.05). The majority of fully recovered infants was from the group with the upper type of lesion (p < 0.05). Early habilitation program is effective in infants with CBP. It is especially effective in the upper root palsy.

Abstract
Candida vaginitis is the second most common vaginal infection which is treatable by azole. Overconsumption of azole is associated with resistance to drug and treatment failure. Studies conducted in laboratory conditions confirm the anti-fungal effects of Artemisia plant. The aim of this study was to compare the effect of vaginal Artemisia cream and clotrimazole on vaginal candidiasis infection. This is a clinical triple-blind trial that was performed on 72 non-pregnant women referred to Mashhad health centers in 2012-2017. After confirmation of Candida infection, the research units were randomly allocated into two groups: Artemisia and clotrimazole vaginal cream recipients treated for 7 nights. After the treatment, the data were analyzed by SPSS software (version 24). The results of the study showed that the mean reduction in the score of signs and symptoms of vaginal Candida infection was 7.4 ± 4. 1 and 7.6 ± 3.8 in the Artemisia and clotrimazole group, respectively. Wilcoxon test showed that improvement in both groups treated by Artemisia and clotrimazole was significantly higher than before treatment (p < 0.001). There was no significant difference between the two groups regarding the improvement of symptoms (p > 0.05). Acta facultatis medicae Naissensis 2018; 35(4):299-310 The present study showed that Artemisia vaginal cream and clotrimazole cream both improved the symptoms related to vaginal Candida infection. In addition, the therapeutic effect of the two drugs was not statistically significant in comparison with each other. Therefore, it can be used as an alternative treatment for vaginal candidiasis.

Abstract
Penis size is a major body image concern for the majority of men in western nations, while in gay culture the penis has become a body part linked to sexual attractiveness and viability. The aim of this study was to reveal influence of the perceived penis size on sexual behaviour, condom use, sexually transmitted infections and men’s sexual positioning among men who have sex with men. In this cross-sectional study, the data were collected from consecutive men who have sex with men who attended Counselling for Sexually Transmitted Diseases at the City Institute for Skin and Venereal Diseases in Belgrade, Serbia. Out of 319 participants, 6.6% perceived their penis as "below average", 71.5% as "average", and 21.9% as "above average". In comparison with men with an average penis, men with below average penis were more frequently unsatisfied with their penis size (p < 0.05), more frequently lied to others about their penis size (p < 0.001) and took more frequently the passive sexual role (p < 0.05). Men with above average penis were more frequently satisfied with their penis size (p < 0.001), took more frequently the active sexual role (p < 0.01), they had more sexual partners (p < 0.05), more problems with a tight condom (p < 0.001) and more gonorrhoea/Chlamydia infections (p < 0.001) than men with an average penis. Perception of one’s penis size was associated with some aspects of sexual behaviour and the frequency of sexually transmitted diseases.
Error Analysis for Determination of Accuracy of Johnson’s Formula, Dare’s Formula and Mother's Opinion for the Estimation of Birth Weight: Results of an Iranian Cross‐Sectional Study
Authors: Alirezaei Somayeh , Azmoude Elham , Ghaderi Asma 
Published: January 2019

Abstract
Accurate fetal weight estimation is important for the management of birth. According to the existing literature, none of the clinical techniques is superior to any other. This study aimed to compare error analysis for the determination of the accuracy of Johnson’s formula, Dare’s formula and mother's opinion for the estimation of birth weight. A cross-sectional study involving 147 full-term, cephalic, singleton pregnancies, was performed. The mother’s opinion was recorded and Johnson’s and Dare’s formulas were used to calculate the fetal weight. Accuracy was determined by percentage error, absolute percentage error, and proportion of estimates within 10% of actual birth-weight. Statistical analysis was done using the RM ANOVA, Friedman and Cochran. P < 0.05 was considered significant. The birth weight was correctly estimated in 34.7%, 58.5%, 66% of the cases using the mother’s estimate, Dare’s and Johnson’s formulas. Respectively the proportion of the mother's estimate and Dare’s formula was significantly lower than that of Johnson’s formula for all birth weights. No significant difference was observed in all the measures of accuracy for the low birth-weight range. The mean error of Johnson's formula in both normal weight and macrosomic groups was less than those obtained by the Dare's formula and mother's opinion. The Johnson’s formula is more accurate in actual birth weight estimation than the Dare ’s one and mother's opinion. In the normal weight range, Johnson’s formula is more accurate of the two, while in the macrosomic group, Dare’s formula appears to be more accurate.

Abstract
Infective endocarditis (IE) is a serious infection among endovascular infections. Fungal endocarditis, especially caused by Candida albicans, is very rare, and its diagnosis is often difficult due to the negative results of blood culture and the presence of nonspecific symptoms. In this study, a patient who developed endocarditis on a normal valve due to infection with Candida albicans is presented.
Finite–Time Adaptive Modified Function Projective Multi–Lag Generalized Compound Synchronization for Multiple Uncertain Chaotic Systems
Authors: Li Qiaoping , Liu Sanyang , Chen Yonggang 
Published: January 2019

Abstract
In this paper, for multiple different chaotic systems with fully unknown parameters, a novel synchronization scheme called ‘modified function projective multi-lag generalized compound synchronization’ is put forward. As an advantage of the new method, not only the addition and subtraction, but also the multiplication of multiple chaotic systems are taken into consideration. This makes the signal hidden channels more abundant and the signal hidden methods more flexible. By virtue of finite-time stability theory and an adaptive control technique, a finite-time adaptive control scheme is established to realize the finite-time synchronization and to properly evaluate the unknown parameters. A detailed theoretical derivation and a specific numerical simulation demonstrate the feasibility and validity of the advanced scheme.
Fault Diagnosis in Nonlinear Hybrid Systems
Authors: Zhirabok Alexey , Shumsky Alexey 
Published: January 2019

Abstract
The problem of fault diagnosis in hybrid systems is investigated. It is assumed that the hybrid systems under consideration consist of a finite automaton, a set of nonlinear difference equations and the so-called mode activator that coordinates the action of the other two parts. To solve the fault diagnosis problem, hybrid residual generators based on both diagnostic observers and parity relations are used. It is shown that the hybrid nature of the system imposes some restrictions on the possibility of creating such generators. Sufficient solvability conditions of the fault diagnosis problem are found. Examples illustrate details of the solution.
A Memory–Efficient Noninteger–Order Discrete–Time State–Space Model of a Heat Transfer Process
Authors: Oprzędkiewicz Krzysztof , Mitkowski Wojciech 
Published: January 2019

Abstract
A new, state space, discrete-time, and memory-efficient model of a one-dimensional heat transfer process is proposed. The model is derived directly from a time-continuous, state-space semigroup one. Its discrete version is obtained via a continuous fraction expansion method applied to the solution of the state equation. Fundamental properties of the proposed model, such as decomposition, stability, accuracy and convergence, are also discussed. Results of experiments show that the model yields good accuracy in the sense of the mean square error, and its size is significantly smaller than that of the model employing the well-known power series expansion approximation.
Interconnection and Damping Assignment Passivity–Based Control of an Underactuated 2–DOF Gyroscope
Authors: Cordero Gustavo , Santibáñez Víctor , Dzul Alejandro , Sandoval Jesús 
Published: January 2019

Abstract
In this paper we present interconnection and damping assignment passivity-based control (IDA-PBC) applied to a 2 degrees of freedom (DOFs) underactuated gyroscope. First, the equations of motion of the complete system (3-DOF) are presented in both Lagrangian and Hamiltonian formalisms. Moreover, the conditions to reduce the system from a 3-DOF to a 2- DOF gyroscope, by using Routh’s equations of motion, are shown. Next, the solutions of the partial differential equations involved in getting the proper controller are presented using a reduction method to handle them as ordinary differential equations. Besides, since the gyroscope has no potential energy, it presents the inconvenience that neither the desired potential energy function nor the desired Hamiltonian function has an isolated minimum, both being only positive semidefinite functions; however, by focusing on an open-loop nonholonomic constraint, it is possible to get the Hamiltonian of the closed-loop system as a positive definite function. Then, the Lyapunov direct method is used, in order to assure stability. Finally, by invoking LaSalle’s theorem, we arrive at the asymptotic stability of the desired equilibrium point. Experiments with an underactuated gyroscopic mechanical system show the effectiveness of the proposed scheme.
Adaptive Backstepping Tracking Control for an over–Actuated DP Marine Vessel with Inertia Uncertainties

Published: January 2019

Abstract
Designing a tracking control system for an over-actuated dynamic positioning marine vessel in the case of insufficient information on environmental disturbances, hydrodynamic damping, Coriolis forces and vessel inertia characteristics is considered. The designed adaptive MIMO backstepping control law with control allocation is based on Lyapunov control theory for cascaded systems to guarantee stabilization of the marine vessel position and heading. Forces and torque computed from the adaptive control law are allocated to individual thrusters by employing the quadratic programming method in combination with the cascaded generalized inverse algorithm, the weighted least squares algorithm and the minimal least squares algorithm. The effectiveness of the proposed control scheme is demonstrated by simulations involving a redundant set of actuators. The evaluation criteria include energy consumption, robustness, as well accuracy of tracking during typical vessel operation.
Comparison of Prototype Selection Algorithms Used in Construction of Neural Networks Learned by SVD
Authors: Jankowski Norbert 
Published: January 2019

Abstract
Radial basis function networks (RBFNs) or extreme learning machines (ELMs) can be seen as linear combinations of kernel functions (hidden neurons). Kernels can be constructed in random processes like in ELMs, or the positions of kernels can be initialized by a random subset of training vectors, or kernels can be constructed in a (sub-)learning process (sometimes by k-means, for example). We found that kernels constructed using prototype selection algorithms provide very accurate and stable solutions. What is more, prototype selection algorithms automatically choose not only the placement of prototypes, but also their number. Thanks to this advantage, it is no longer necessary to estimate the number of kernels with time-consuming multiple train-test procedures. The best results of learning can be obtained by pseudo-inverse learning with a singular value decomposition (SVD) algorithm. The article presents a comparison of several prototype selection algorithms co-working with singular value decomposition-based learning. The presented comparison clearly shows that the combination of prototype selection and SVD learning of a neural network is significantly better than a random selection of kernels for the RBFN or the ELM, the support vector machine or the kNN. Moreover, the presented learning scheme requires no parameters except for the width of the Gaussian kernel.
