The usefulness of the addition of fermented herbs (katuk/Sauropus androgynusplus bay leaves) onfat accumulation, and chemical, amino acids and fatty acids composition ofbroiler meats was investigated.At 15 days of age, 280female broilers were divided into seven treatments, as follows:T0) the control;T1) broilers were given a ration with 2.5% fermented katuk plus bay leaf mixture formula 1;T2) broilerswere givena ration with 2.5% fermented katuk plus bay leaf mixture formula 2;T3) broilerswere givena ration with2.5% fermented katuk plus bay leaf mixture formula 3;T4) broilers were given a rationswith 5% fermented katuk plus bay leaf mixture formula 1;T5) broilers were givena ration with 5% fermented katuk plus bay leaf mixture formula 2;T6) broilers were givena ration with 5% fermented katuk plus bay leaf mixture formula 3. The results of this study showed that the administration of fermented herbs to the ration significantly reduced abdominal fat, gizzard fat, total fat deposition, meat fat, and cholesterol contents. Their inclusions changed calcium, iron, moisture, serine, threonine, arginine, valine, lysine, methionine, myristic acid, pentadecanoic acid, palmitic acid, oleic acid, linolenic acid, cis-11,14-eicosadienoic acid, cis-5,8,11,14,17-eicosapentaenoic acid, and n-3 unsaturated fatty acids of female broiler meats. It can be concluded that administration of fermented herbs formula 2 at5% levels producedchicken meat with lowerfat and cholesterol levels, but higher protein, minerals and n-3 unsaturated fatty acidslevels.
Wechselwirkungen zwischen Mindestlohn und Tariflohn
Authors: Dingeldey Irene 
Published: March 2019

ZusammenfassungDie Wechselwirkungen zwischen gesetzlichem Mindestlohn und Tarifpolitik sind erst seit kurzem im Fokus der vergleichenden Forschung. Ausgehend von der Segmentation des Tarifsystems zeigt der Beitrag, dass die Einführung des gesetzlichen Mindestlohns mit unterschiedlichen Wirkungstypen innerhalb Deutschlands einhergeht. Vor allem in Branchen mit geringem Lohnniveau kommt es zu einer Dominanz des Mindestlohns. Sind dagegen das Tariflohnniveau wie auch die Tarifbindung hoch, ist der Mindestlohn ohne Bedeutung. Es gibt jedoch auch Branchen, wo der gesetzliche Mindestlohn als Referenzpunkt für Tariflohnerhöhungen gilt, um die unteren Lohngruppen (knapp) über dem Mindestlohn festzulegen. Da die jeweilige Höhe der Tariflohnerhöhungen wiederum die nachfolgende Anpassung des Mindestlohns beeinflusst, liegt hier eine explizite Wechselwirkung vor.
Design and Analysis of Full and Half Mode Substrate Integrated Waveguide Planar Leaky Wave Antenna with Continuous Beam Scanning in X-Ku Band
Authors: Prakash Ved , Kumawat Sunita , Singh Priti 
Published: March 2019

AbstractIn this paper, substrate-integrated waveguide (SIW) and half mode substrate integrated waveguide (HM-SIW) periodic leaky wave antennas (LWAs) are presented for the antenna applications. The continuous beam scanning (CBS) is realized by optimizing the unit cell by matching its impedance to the characteristic impedance of the waveguide. This leaky wave antenna is capable of total 60 ° scanning from −38 ° to + 22 ° as the frequency changes from 10.17 GHz to 16.3 GHz with a maximum gain of 11 dBi. Moreover, for further miniaturization, HM-SIW technology is employed in the presented LWA. This LWA is also capable of CBS from −50 ° to + 26 ° in the frequency band of 10 GHz to 16.5 GHz with a maximum gain of 12 dBi. The final prototypes of the both these antenna are fabricated and measured results are in agreement with the simulated ones.
Microstrip Lowpass Filter with Ultra-Wide Stopband Using Folded Structures

Published: March 2019

Abstract
In this article, a new microstrip lowpass filter with ultra-wide stopband using T-shaped resonators and folded structures is described. The structure of this filter is very simple, so that only a T-shaped resonator is used as main resonator without any particular changes in these resonators. The designed T-shaped main resonator has a −3 dB cut-off frequency of 1.4 GHz. On the other hand, T-shaped resonators with low base length are utilized as suppressing cells. To provide an ultra-wide stopband, two pair of T-shaped resonator and two high frequency suppressing cells are employed. The structure of this filter is folded to have compact size. The measured results shows −3 dB cut-off frequency of 1.4 GHz. The transition band is equal to 0.25 GHz from 1.4 to 1.65 GHz, with corresponding attenuation levels of −3 to −20 dB. The ultra-wide stopband with −22 dB suppression level is from 1.68 to 40 GHz. Also, the total size of the proposed lowpass filter is 16.8×11.3 mm2.

On laminar groups, Tits alternatives and convergence group actions on 𝑆2
Authors: Alonso Juan , Baik Hyungryul , Samperton Eric 
Published: March 2019

AbstractFollowing previous work of the second author, we establish more properties of groups of circle homeomorphisms which admit invariant laminations. In this paper, we focus on a certain type of such groups, so-called pseudo-fibered groups, and show that many 3-manifold groups are examples of pseudo-fibered groups. We then prove that torsion-free pseudo-fibered groups satisfy a Tits alternative. We conclude by proving that a purely hyperbolic pseudo-fibered group acts on the 2-sphere as a convergence group. This leads to an interesting question if there are examples of pseudo-fibered groups other than 3-manifold groups.

Abstract
A discrete nonlinear almost periodic multispecies competitive system with delays and feedback controls is proposed and investigated. We obtain sufficient conditions to ensure the permanence of the system. Also, we establish a criterion for the existence and uniformly asymptotic stability of unique positive almost periodic solution of the system. In additional, an example together with its numerical simulation are presented to illustrate the feasibility of the main result.
Augmented, free and tensor generalized digroups
Authors: Rodríguez-Nieto José Gregorio , Salazar-Díaz Olga P. , Velásquez Raúl 
Published: March 2019

Abstract
The concept of generalized digroup was proposed by Salazar-Díaz, Velásquez and Wills-Toro in their paper “Generalized digroups” as a non trivial extension of groups. In this way, many concepts and results given in the category of groups can be extended in a natural form to the category of generalized digroups. The aim of this paper is to present the construction of the free generalized digroup and study its properties. Although this construction is vastly different from the one given for the case of groups, we will use this concept, the classical construction for groups and the semidirect product to construct the tensor generalized digroup as well as the semidirect product of generalized digroups. Additionally, we give a new structural result for generalized digroups using compatible actions of groups and an equivariant map from a group set to the group corresponding to notions of associative dialgebras and augmented racks.

On the equivalence of various definitions of mixed poisson processes
Authors: Lyberopoulos Demetrios P. , Macheras Nikolaos D. , Tzaninis Spyridon M. 
Published: March 2019

Abstract
Under mild assumptions the equivalence of the mixed Poisson process with mixing parameter a real-valued random variable to the one with mixing probability distribution as well as to the mixed Poisson process in the sense of Huang is obtained, and a characterization of each one of the above mixed Poisson processes in terms of disintegrations is provided. Moreover, some examples of “canonical” probability spaces admitting counting processes satisfying the equivalence of all above statements are given. Finally, it is shown that our assumptions for the characterization of mixed Poisson processes in terms of disintegrations cannot be omitted.

Published: March 2019

Abstract
In this work, we consider the optimal harvesting and stability problems of a prey-predator model with modified Leslie-Gower and Holling-type II functional response. The model is governed by a system of three differential equations which describe the interactions between prey, predator and harvesting effort. Boundedness and existence of solutions for this system are showed. The existence and local stability of the possible steady states are analyzed and the conditions of global stability of the interior equilibrium are established by using the Lyapunov function, we prove also the occurrence of Hopf bifurcation at this point. By using the Pontryagin’s maximal principle, we formulate and we solve the problem of the optimal harvest policy. In the end, some numerical simulations are given to support our theoretical results.

Authors: Iacoi Anna , Brobeil Alexander , Götte Malena , Enzensberger Christian , Müller Vera , Gattenlöhner Stefan , Axt-Fliedner Roland 
Published: March 2019

Abstract
Pulmonary capillary haemangiomatosis (PCH) is a rare disorder of the lung, well described in adult literature. PCH is characterized by capillary proliferation, infiltrating the interstitium and alveolar walls. This leads to development of respiratory distress and to end-stage pulmonary hypertension. Mostly young adults are affected. The affection of newborn is described in less than ten cases in literature in the past forty years. PCH is a mostly deadly ending disease. We present a preterm born infant with antepartal diagnosed hydrops fetalis, who died 30 minutes after birth. Autopsy revealed PCH as lethal reason and not cardial disease as presumed before.
Non-reciprocal Transmission of Electromagnetic Waves in Asymmetric Photonic Crystals
Authors: Yu Guanxia , Du Wenwen , Zhang Xiaomeng , Luo Min , Xia Lijuan 
Published: March 2019

Abstract
The non-reciprocal transmission properties of transverse electric (TE) mode waves are investigated for two asymmetric, complex photonic crystals composed of magnetic gyrotropic and normal media. Three pairs of non-reciprocal transmission peaks in three different bandgaps for forward and backward waves occur because of optical Tamm states (OTSs) at the interface between the photonic crystals. Numerical results indicate that the non-reciprocal transmission properties are influenced by the incident angles, gyrotropic permeability, and number of layers of the photonic crystals. The asymmetric structure with multiple non-reciprocal transmission peaks at a certain incident angle can provide promising opportunities for the design of multichannel isolators.
Viscous Dissipation Effect on a Steady Generalised Couette Flow of Heat-Generating/Absorbing Fluid in a Vertical Channel
Authors: Ajibade Abiodun O. , Kabir Tafida M. 
Published: March 2019

Abstract
This article investigates the viscous dissipation effect on steady generalised Couette flow of heat-generating/absorbing fluid in a vertical channel. Equations of energy and momentum are obtained and solved using the homotopy perturbation method. The influences of the dimensionless flow parameter have been plotted graphically and discussed for varying values of the controlling parameters. During the course of computation, it is found that fluid temperature and velocity increase with an increase in viscous dissipation and also seen that growing mixed convection parameter Gre leads to a corresponding rise in temperature and velocity. It is further discovered that heat absorption leads to increase in the heat transfer on the heated wall. Finally, it is concluded that heat generation contributes to increase the mixed convection, hence, it requires decrease in mixed convection parameter to bring about a reverse flow near the stationary plate.

Published: March 2019

Abstract
A potassium tetranitratopalladate(II) with the composition K2[Pd(NO3)4] · 2HNO3 was synthesized by a simple solvothermal process in a glass ampoule. The new compound crystallizes in the monoclinic space group P21
/c (no. 14) with the lattice parameters a = 1017.15(4), b = 892.94(3), c = 880.55(3) Å, and β = 98.13(1)° (Z = 2). The crystal structure of K2[Pd(NO3)4] · 2HNO3 reveals isolated complex [Pd(NO3)4]2− anions, which are surrounded by eight potassium cations and four HNO3 molecules. The complex anions and the cations are associated in layers which are separated by HNO3 molecules. K2[Pd(NO3)4] · 2HNO3 can thus be regarded as a HNO3 intercalation variant of β-K2[Pd(NO3)4]. The characterization is based on single-crystal X-ray and powder X-ray diffraction.

Published: March 2019

Abstract
The adsorption of methylene blue was carried out by adsorbent prepared from Acacia modesta. The sample wood was collected from Dir lower Khyber Pakhtunkhwa Pakistan. Chemical activation of the sample was conducted for surface efficiency. Surface of raw and activated sample was elucidated by scanning electron microscope (SEM), energy dispersive spectroscopy (EDS) and Fourier transform infrared (FTIR) techniques. Adsorption of methylene blue was studied on raw and activated samples by kinetics adsorption at different adsorption temperatures such as 20 °C, 30 °C and 40 °C. The adsorption equilibrium was established within 2 h. Elovich, Bhangam, and Parabolic diffusion equations were applied to the adsorption kinetics data and were found fit for adsorption. From adsorption kinetic data the parameters like ΔH≠, ΔS≠ and ΔE≠ were calculated and showed that the adsorption process was spontaneous process. Entropy in descending order shows that dye molecules adsorbed in an oriented position.
“That Free Play of Human Affection”: The Humanist Ethics of Walter Pater’s The Renaissance
Authors: Albrecht Thomas 
Published: March 2019

Thomas Albrecht, “‘That Free Play of Human Affection’: The Humanist Ethics of Walter Pater’s The Renaissance” (pp. 486–521)
This essay aims to refute received, persistent misconceptions of Walter Pater’s Studies in the History of the Renaissance (1873), and of aestheticism generally, as an asocial and amoral sensualism, and as a deliberate separating of art from human lives and the world. Contrary to these misconceptions, it finds a humanist ethical vision in The Renaissance, specifically in the essays Pater devotes to Botticelli, Michelangelo, and Leonardo da Vinci. Drawing on an established post-Enlightenment, post-Romantic tradition of Victorian secular humanism, Pater defines this vision in terms of human sympathies for the feelings and suffering of other persons. And he defines it in aesthetic terms, in terms of art’s unique capacity to depict human feelings and suffering, and thereby to arouse sympathies in the viewer. At the same time, the essay contends that Pater in The Renaissance also defines his ethical vision in a more unprecedented, radical way. Beyond the solicitation of human sympathies, he frames it in terms of a fundamental uncertainty and unpredictability, a fundamental freedom and singularity, of human ethical relationships and responses. For Pater, this uncertainty and freedom are the qualities that make an ethics genuinely ethical. Pater finds these qualities, and this kind of genuine ethics, epitomized in the unpredictability and freedom of human aesthetic responses, including his own, to art and beauty.
Plurihormonal Pit-1 lineage adenoma presenting as meningitis with recurrence after somatostatin analogue
Authors: Olmedilla Yoko , Khan Shoaib , Young Victoria , Joseph Robin , Cudlip Simon , Ansgorge Olaf , Grossman Ashley , Pal Aparna 
Published: March 2019

Summary
A 21 year-old woman was found to have a pituitary macroadenoma following an episode of haemophilus meningitis. Biochemical TSH and GH excess was noted, although with no clear clinical correlates. She was treated with a somatostatin analogue (SSA), which restored the euthyroid state and controlled GH hypersecretion, but she re-presented with a further episode of cerebrospinal fluid (CSF) leak and recurrent meningitis. Histology following transsphenoidal adenomectomy revealed a Pit-1 lineage plurihormonal adenoma expressing GH, TSH and PRL. Such plurihormonal pituitary tumours are uncommon and even more unusual to present with spontaneous bacterial meningitis. The second episode of CSF leak and meningitis appears to have been due to SSA therapy-induced tumour shrinkage, which is not a well-described phenomenon in the literature for this type of tumour.

Learning points:

Pit-1 lineage GH/TSH/PRL-expressing plurihormonal pituitary adenomas are uncommon. Moreover, this case is unique as the patient first presented with bacterial meningitis.

Inmunohistochemical plurihormonality of pituitary adenomas does not necessarily correlate with biochemical and clinical features of hormonal hypersecretion.

Given that plurihormonal Pit-1 lineage adenomas may behave more aggressively than classical pituitary adenomas, accurate pathological characterization of these tumours has an increasing prognostic relevance.

Although unusual, a CSF leak and meningitis may be precipitated by SSA therapy of a pituitary macroadenoma via tumour shrinkage.
Cushing syndrome: uncovering Carney complex due to novel PRKAR1A mutation
Authors: Zhang Catherine D , Pichurin Pavel N , Bobr Aleh , Lyden Melanie L , Young William F , Bancos Irina 
Published: March 2019

Summary
Carney complex (CNC) is a rare multiple neoplasia syndrome characterized by spotty pigmentation of the skin and mucosa in association with various non-endocrine and endocrine tumors, including primary pigmented nodular adrenocortical disease (PPNAD). A 20-year-old woman was referred for suspected Cushing syndrome. She had signs of cortisol excess as well as skin lentigines on physical examination. Biochemical investigation was suggestive of corticotropin (ACTH)-independent Cushing syndrome. Unenhanced computed tomography scan of the abdomen did not reveal an obvious adrenal mass. She subsequently underwent bilateral laparoscopic adrenalectomy, and histopathology was consistent with PPNAD. Genetic testing revealed a novel frameshift pathogenic variant c.488delC/p.Thr163MetfsX2 (ClinVar Variation ID: 424516) in the PRKAR1A gene, consistent with clinical suspicion for CNC. Evaluation for other clinical features of the complex was unrevealing. We present a case of PPNAD-associated Cushing syndrome leading to the diagnosis of CNC due to a novel PRKAR1A pathogenic variant.

Learning points:

PPNAD should be considered in the differential for ACTH-independent Cushing syndrome, especially when adrenal imaging appears normal.

The diagnosis of PPNAD should prompt screening for CNC.

CNC is a rare multiple neoplasia syndrome caused by inactivating pathogenic variants in the PRKAR1A gene.

Timely diagnosis of CNC and careful surveillance can help prevent potentially fatal complications of the disease.
Probes for the study of icy and subglacial environment of planets
Authors: Zelenchuk A. V. , Krylenkov V. A. 
Published: March 2019

The article proposes a technology for increasing the thermic ice drilling rate under the influence of hydraulic force generated by the probe (or cryobot), which increases the coefficient of conversion of thermal energy into the energy of ice melting and allows increasing the power of thermal head of the probe. A single-wire Tesla system is proposed to use for the probe power supply, which makes it possible to reduce the volume of the cable and losses of transmitted energy. The method of the probe self-lifting to the ice surface without using the hydraulic force (traction), i.e. without a load on the cable, is proposed. To study thick (up to 5 km) ice sheets and subglacial water environments on the Earth, as well as the ice cover (up to 30 km thick) and the subglacial ocean of the Europe (the Jupiter’s satellite), conceptual principal designs of the probe (or cryobot) have been developed on the basis of thermic-hydraulic drilling (THD). Implementation of the THD‑cryobot designs will allow organizing systemic studies of glaciers and subglacial water environments on the Earth and other planets, not disturbing their ice isolation with multiple savings of financial and technical means, energy and time.
