Formação de classes de respostas, resistência à mudança e terapia comportamental infantil
Authors: Regra Jaíde Aparecida Gomes
Published: June 2018

Compreender o processo de formação de classes de respostas pode auxiliar na análise do comportamento complexo. A resistência à mudança dificulta o trabalho do terapeuta comportamental. Identificar variáveis que favorecem o desdobramento de classes de respostas é um desafio para o analista do comportamento. O objetivo do presente trabalho é identificar variáveis relevantes que dificultam a formação de nova classe de resposta e intervenções que alterem as classes de respostas pré-estabelecidas. Estudos recentes mostram dificuldades na aquisição de nova classe de resposta quando outra classe já tenha sido anteriormente estabelecida. É importante considerar tanto a aversividade dos estímulos presentes na formação da nova classe de resposta como a sobreposição do comportamento operante e respondente. A análise de amostras de interações entre terapeuta e criança mostra pequenas mudanças de respostas verbais. A intervenção pretendeu desdobrar uma classe de resposta em duas classes menores. Ao identificar novas classes de respostas e suas consequências, a criança pode alterar a classe de resposta anterior. Esta análise sugere que as alterações ocorridas nas classes de respostas resistentes possam ter a função de expor a criança a novas contingências.
Logics with Impossibility as the Negation and Regular Extensions of the Deontic Logic D2
Authors: Mruczek-Nasieniewska Krystyna , Nasieniewski Marek
Published: June 2018

In [1] J.-Y. Bèziau formulated a logic called Z. Bèziau’s idea was generalized independently in [6] and [7]. A family of logics to which Z belongs is denoted in [7] by K. In particular; it has been shown in [6] and [7] that there is a correspondence between normal modal logics and logics from the class K. Similar; but only partial results has been obtained also for regular logics (see [8] and [9]). In (Došen; [2]) a logic N has been investigated in the language with negation; implication; conjunction and disjunction by axioms of positive intuitionistic logic; the right-to-left part of the second de Morgan law; and the rules of modus ponens and contraposition. From the semantical point of view the negation used by Došen is the modal operator of impossibility. It is known this operator is a characteristic of the modal interpretation of intuitionistic negation (see [3; p. 300]). In the present paper we consider an extension of N denoted by N+. We will prove that every extension of N+ that is closed under the same rules as N+; corresponds to a regular logic being an extension of the regular deontic logic D21 (see [4] and [13]). The proved correspondence allows to obtain from soundnesscompleteness result for any given regular logic containing D2, similar adequacy theorem for the respective extension of the logic N+.
„Suchą stopą” czy „skacząc w fale”. Przekraczanie rzek przez wojska polskie od XI do początku XVI wieku
Authors: Grabarczyk Tadeusz
Published: June 2018

Najczęstszym sposobem przekraczania rzeki było przechodzenie jej w bród. Wiele informacji o takich przeprawach pochodzi z lat wojny polsko-niemieckiej (1003–1018). Obie walczące wówczas armie kilkukrotnie przekraczały Odrę i Łabę, których szerokość sięgała 100 m. Największą rzeką pokonaną przez polskie wojska w bród był Dniestr, który miał szerokość 150 m. Nieliczne wzmianki dotyczą przepraw przez rzeki zamarznięte. Mosty pływające, które zostały umieszczone na dolnych odcinkach Wisły, stały się trwałym elementem wojen polsko-krzyżackich w XV w. Pierwsze wzmianki o takich mostach w Polsce pochodzą z 1410 r. Wtedy podczas wojny przeciwko zakonowi krzyżackiemu wybudowano je trzy: na Wiśle pod Czerwińskiem i pod Przypustem oraz na Narwi pod Pułtuskiem. Od tego czasu pływające mosty były regularnie używane podczas wojny przeciwko Zakonowi. Zbudowano je na Wiśle: w 1414 r. pod Zakroczymiem, w 1419 i 1422 r. ponownie pod Czerwińskem, w 1454 r. pod Toruniem i w 1455 r. pod Grudziądzem. Podczas polskiej kampanii do Mołdawii w 1497 r. król Jan Olbracht nakazał postawić most nad Dniestrem koło Halicza. Jednak ostatecznie zmienił swoje plany i z niego nie skorzystał. Dwa mosty pływające, oparte na beczkach, zbudowano w nocy w dniach 7–8 września 1514 r. Były one użyte przez wojska litewskie i polskie, które w bitwie pod Orszą rozbiły armię Wielkiego Księstwa Moskiewskiego. Głównym powodem, dla którego armie zostały zmuszone do przekraczania mostów na szerokich rzekach, była duża liczba wozów i artylerii zabieranych na wyprawę. W XV i na początku XVI w., wykorzystując pływające mosty, armia Królestwa Polskiego bez większych problemów była w stanie przeprawić się przez Wisłę, nawet jeśli szerokość przekraczała 500 m.
Przemieszczanie się partii powstańczych podczas powstania styczniowego
Authors: Kita Jarosław
Published: June 2018

Podczas powstania styczniowego ze względu na partyzancki charakter walk i przygniatającą przewagę wojsk rosyjskich niezmiernie istotną rolę odgrywało przemieszczanie się partii powstańczych. Wiele zależało w tym względzie od umiejętności i inwencji dowódców poszczególnych oddziałów powstańczych. W sytuacji, kiedy nie było zagrożenia ze strony nieprzyjaciela, marsze odbywały się według ustalonych zasad, zawsze jednak z odpowiednim ubezpieczeniem kolumny marszowej. Jednak najczęściej partie powstańcze musiały się ukrywać i maszerować nocami lub przez wiele godzin, a nawet dni, uciekać przed ścigającymi je Rosjanami. Podczas marszów powstańcy stosowali wiele różnych działań maskujących i wprowadzających wroga w błąd. Negatywną konsekwencją tej wymuszonej mobilności był niemal tułaczy tryb życia, jaki wiedli insurgenci styczniowi. Powstańcy wracali do domów, jednak trudy partyzanckiego charakteru walki, a w tym nieustanne przemieszczanie się partii powstańczych, pozostawały w ich pamięci na długie lata, na co wyraźnie wskazuje analiza niejednego pamiętnika.
Kanał do zdobycia – egipskie założenia przeprawy przez Kanał Sueski w przededniu wojny październikowej z 1973 roku
Authors: Pogońska-Pol Magdalena
Published: June 2018

W wyniku wojny czerwcowej z 1967 r. Izrael opanował egipski Półwysep Synaj. Linią rozdzielającą obie strony stał się Kanał Sueski. Izrael, aby zabezpieczyć swój stan posiadania i uchronić się przed nową wojną, wybudował na wschodnim brzegu Kanału system fortyfikacji zwany linią Bar-Leva. Armia egipska, chcąc odzyskać utracony obszar, musiała opracować plany przekroczenia Kanału Sueskiego, a co za tym idzie – uwzględnić specyfikę budowy Kanału, warunki hydrograficzne i system opracowany przez Izraelczyków, w tym bariery z piasku, zagrożenie wywołane pożarem na Kanale. Egipcjanie musieli również opracować sposób przeprawienia się wojsk korpusu inżynieryjnego, piechoty, a następnie czołgów. Wszystkie kwestie zawierał plan opracowany przez S. Shazlyego zwany operacją „Badr”, a skuteczność planowania potwierdzona została 6 października 1973 r., w dniu rozpoczęcia wojny październikowej.
Szanse na rozwój gospodarki okrężnej w przemyśle tekstylno‑odzieżowym
Authors: Szewczyk Monika
Published: June 2018

Gospodarka okrężna to odpowiedź na potrzebę zmniejszania oddziaływania na środowisko naturalne. Zamykanie obiegów produkcyjnych to odejście od dotychczasowego modelu linearnego, dostarczającego ogromne ilości odpadów. Model circular economy opiera się nie tylko na ekoefektywności, ale i na odpowiednim podejściu – od etapu projektowania produktu aż po jego ponowne wykorzystanie. Celem nadrzędnym gospodarki okrężnej jest zmniejszenie ilości produkowanych odpadów do minimum lub zupełne ich wyeliminowanie. Przemysł tekstylno‑odzieżowy jest jedną z najbardziej zanieczyszczających branż na świecie, generuje odpady głównie w postaci ubrań. Problem ogromnej ilości produkowanej odzieży jest dodatkowo potęgowany przez ideę fast fashion i nadmierny konsumpcjonizm. Artykuł przedstawia kroki, które powinny być podjęte w celu wdrożenia podstawowych założeń circular economy, jednocześnie pokazując potencjał rozwoju tej koncepcji w branży odzieżowej. Dzięki wnikliwej analizie możliwe było określenie i wskazanie konkretnych rozwiązań będących szansą na rozwój gospodarki o obiegu zamkniętym w przemyśle tekstylno‑odzieżowym. Autorka wyjaśnia także podstawowe założenia gospodarki o obiegu zamkniętym oraz wskazuje na specyficzne cechy przemysłu tekstylno‑odzieżowego i jego wpływ na środowisko naturalne.
W kierunku studentyfikacji? Zakwaterowanie studenckie w polskich miastach akademickich
Authors: Zasina Jakub
Published: June 2018

Zakwaterowanie studenckie zyskało w ostatnich latach szczególną uwagę badaczy. Doświadczenia brytyjskie wskazują, że rynki zakwaterowania prywatnego adresowanego do studentów zaczęły dynamicznie rozwijać się w tamtejszych miastach akademickich wskutek umasowienia szkolnictwa wyższego. Celem artykułu jest omówienie tych doświadczeń w kontekście polskim. Przedstawiono w nim zmianę populacji studentów w 18 dużych ośrodkach akademickich kraju oraz ich liczby i odsetka korzystającego z zakwaterowania oferowanego przez uczelnie. Wskazano, że między rokiem 2004 i 2014 populacja studentów uległa zwiększeniu w 10 spośród analizowanych ośrodków, a liczba i odsetek studentów zakwaterowanych w uczelnianych akademikach zmalały w 17 ośrodkach. W omawianej dekadzie polskie miasta akademickie mogły zatem doświadczyć wzrostu liczby studentów poszukujących zakwaterowania na rynku prywatnym.

Authors: Wiśniewska Anna
Published: June 2018

Celem artykułu jest określenie, na terenie których polskich województw turystyka najlepiej spełnia kryteria zrównoważonego rozwoju. Aby zrealizować cel badawczy, postawiono hipotezę, która brzmi: „Obszarami recepcji turystyki zrównoważonej w 2015 roku były województwa położone na północy i południu Polski”. Badanie turystyki zrównoważonej musi brać pod uwagę zarówno pozytywny, jak i negatywny wpływ tej gałęzi gospodarki na środowisko i społeczeństwo, dlatego aby zweryfikować hipotezę badawczą, zastosowano taksonomiczny miernik rozwoju. W badaniu uwzględniono zmienne stricte dotyczące turystyki oraz te związane pośrednio z jej rozwojem na danym terenie. W kwestii kryteriów merytorycznych doboru zmiennych brano pod uwagę stan wiedzy w obszarze nauk o turystyce i nauk ekonomicznych. Przeprowadzona analiza wykazała, że część polskich województw może zostać uznana za obszary recepcji turystyki zrównoważonej.
Noble estates and their owners in the Orłów county in the second half of the 18th century
Authors: Kobierecki Michał
Published: June 2018

The Orłów county, being one of the smallest in the Polish-Lithuanian Commonwealth, was a part of the Łęczyca voivodship. The towns, villages and other real estate in this county belonged exclusively to the nobility and to the Catholic Church. The contemporary historians investigating the ownership of these properties in the 16th and 17th centuries unambiguously determined that the accumulation of properties and creation of large estates made up of a dozen or more villages did not occur in the said county. The owners of noble estates were not too wealthy, neither in the country nor in the voivodship. The situation did not change in the next century, as confirmed by the study into the records of the chimney tax in 1775 and the head tax in 1790, which covered the entire Łęczyca voivodship. At the time, the most affluent was the voivode of Łęczyca, Szymon Dzierzbicki, being in possession of the town of Bielawa and eight villages, as well as the voivode of Vitebsk, Józef Sołłohub, the owner of Żychlin, six full villages and a part. In 1790, the largest property, including six villages, belonged to the general of the Russian army, Jan Sołłohub. It confirms that no noble estate that would be composed of over ten towns existed in the Orłów county. The area was dominated by small estates, consisting of one or two villages, or their parts, which mainly belonged to the less affluent nobility. In some cases, a village was owned by two or three noblemen, but sometimes even by thirteen. Over the next 15 years, the situation has not changed significantly since the process of property consolidation did not take place. The group of landowners did not grow smaller, and the analysis of the number of chimneys in the villages of the Orłów county in 1790 indicated that a considerable part of the Orłów nobility was working the land and was also tax exempt for having small estate.

KARIJERNA ADAPTABILNOST KAO MEDIJATOR ODNOSA IZMEĐU MRAČNE TRIJADE I STAVOVA PREMA ORGANIZACIONIM PROMENAMA
Authors: Suvajdžić Katarina
Published: June 2018

Cilj ovog istraživanja je da se ispitaju odnosi između osobina mračne trijade i stavova prema organizacionim promenama, kao i da se utvrdi da li je karijerna adaptabilnost značajan medijator ovih odnosa. Na uzorku od 390 zaposlenih (42% muškog pola) u organizacijama u Srbiji primenjene su Skala stavova prema organizacionim promenama (OP), Kratka skala mračne trijade (Short Dark Triad - SD3) i Skala karijerne adaptabilnosti (Career Adapt-Abilities Scale - CAAS 2.0). Rezultati su pokazali da sve tri dimenzije mračne trijade imaju direktan efekat na negativan odnos zaposlenih prema organizacionim promenama. Na iniciranje promena direktan efekat ima samo narcizam, dok na fleksibilnost zaposlenih direktan efekat ostvaruje samo psihopatija. Rezultati, takođe, pokazuju da narcizam ostvaruje i indirektne efekte na sve tri dimenzije stavova prema organizacionim promenama, preko karijerne adaptabilnosti.

Published: June 2018

The study was to determine the concentrations of Zn in porewater and fine roots of Rhizophora sp., and to examine their interactions with mangrove densities and physico-chemical. Porewater samples, fine roots,  and sediments were collected in a 100 m2 plot at each site with different mangrove densities. The average Zn concentrations in mangrove roots in the study area were 0 – 58.21 mg/kg, suggested the capability of mangrove roots in retaining Zn. The average dissolved Zn concentrations in porewater were 0.63 mg/L – 3.50 mg/L, illustrated the amount of Zn bioavailable form and its potential release to the adjacent environment. The Zn concentrations in porewater did not correlate significantly with the densities of mangroves. The concentrations of Zn in roots increased as the densities were higher, which is possibly caused by the absence of mangrove at Site 1. The study discovered the important roles of organic content and silt/clay in Zn sorption thus affect Zn levels in porewater. The concentrations of Zn in mangrove roots increased as the pH of sediment and porewater decreased.

Published: June 2018

Ag nanoparticles were synthesized by laser ablation using an Ag plate in distilled water. This method was performed using a laser with a wavelength of 532 nm and energy of 30 mJ for 60 min. Ag nanoparticles successfully formed, confirmed by the selected area electron diffraction (SAED) which revealed four principal crystal planes of (111), (200), (220) and (311). The size distribution of Ag nanoparticles ranged from 5 to 40 nm, as estimated from electron imaging observed by transmission electron microscope (TEM). Ascorbic acid was used as the analyte to test the characteristics of surface-enhanced Raman scattering (SERS) of colloidal Ag nanoparticles. The concentration of ascorbic acid (1.0, 0.5 and 0.25 wt%) and incubation time (0 and 6 h) were varied to determine the limit of detection and the effect of incubation time. The Raman scattering spectroscopy results showed that the colloidal Ag nanoparticle substrate improved the signals for detection of ascorbic acid.
Studies on Synthesis, Characterization, and Adsorption of Cationic Dyes from Aqueous Solutions Using Magnetic Composite Material from Natural Clay in Central Kalimantan, Indonesia
Authors: Sadiana I Made , Karelius Karelius , Agnestisia Retno , Fatah Abdul Hadjranul
Published: June 2018

Clay is a natural material from crystalline silicate with layered structures, has high cation exchange capacity, and large surface area. These advantages can be used as an adsorbent for the removal of contaminants in aqueous solutions, such as heavy metals and dyes. In Indonesia, clays from Java, Sulawesi, and Sumatra islands have been used as adsorbent, furniture, and construction materials. Due to limited information about basic characteristics of clay from Kalimantan, this clay has not been utilized well. Therefore, natural clay from Kalimantan, especially in Central Kalimantan, was used as adsorbent of cationic dyes in this present study. However, the clay has difficulty for separating the solid phase from aqueous solution after adsorption process. To solve this problem, combining clay with magnetic material was opted. The objectives of this study are to synthesize the magnetic composite material from natural clay by coprecipitation method and to characterize the synthesized magnetic composite material using an x-ray diffraction method, transmission electron microscopy, and vibrating sample magnetometer. The adsorption properties of the synthesized magnetic composite material were evaluated using rhodamine B and methylene blue dyes in aqueous solution. Before magnetic composite material was synthesized, the clay was previously being activated for removing impurities. The magnetic material formed in the structure of clay had magnetite with particle size of 2.75 nm and the magnetization value of 24.91emu/g. The adsorption capacities of natural clay, activated clay, and magnetic composite of clay in rhodamine B were 34.29, 76.27, and 81.46 mg/g, respectively, while in methylene blue were 30.25, 83.92, and 133.90 mg/g, respectively. These results suggested that magnetic composite of clay can increase the adsorption capacities against dyes and accelerate the separation of the adsorbent solid phase from aqueous solution with largest adsorption capacity on methylene blue dye.

Diabetes mellitus is a state of chronic hyperglycemia which causes various complications. Traditionally, The Tithonia diversifolia (Hemsley) A Gray leaf has long been used for the treatment of diabetes. The aim of this study is to investigate the effect of the T. diversifolia leaf on blood glucose, polyphagia, and weight loss in a diabetic rat model. Rats were made diabetic with intraperitonial injection of Nicotinamide and Streptozotocin and divided into 5 groups. Group 1 were healthy rats, group 2 were diabetic rats, while groups 3, 4, and 5 were diabetic rats treated with 25, 50, and 100 mg/kg body weight of 70% ethanol extract of Tithonia diversifolia leaf respectively for 28 days. Blood was taken after treatment for measuring glucose. The ethanol extract of T. diversifolia leaf decreased blood glucose in diabetic rats (P<0.05). The ethanol extract of T. diversifolia leaf significantly suppresses polyphagia and improves diabetic rat weight (P <0.05). In conclusion, Tithonia diversifolia ethanolic extract has anti-hyperglycemic effect and ameliorated the effect of diabetes mellitus symptoms, namely polyphagia and weight loss.
Deficits in Voice-Identity Processing: Acquired and Developmental Phonagnosia
Authors: Roswandowitz Claudia , Maguinness Corrina , von Kriegstein Katharina
Published: June 2018

The voice contains elementary social communication cues, conveying speech, as well as paralinguistic information pertaining to the emotional state and the identity of the speaker. In contrast to vocal-speech and vocal-emotion processing, voice-identity processing has been less explored. This seems surprising, given the day-to-day significance of person recognition by voice. A valuable approach to unravel how voice-identity processing is accomplished is to investigate people who have a selective deficit in recognising voices. Such a deficit has been termed phonagnosia. In the present chapter, we provide a systematic overview of studies on phonagnosia and how they relate to current neurocognitive models of person recognition. We review studies that have characterised people who suffer from phonagnosia following brain damage (i.e. acquired phonagnosia) and also studies, which have examined phonagnosia cases without apparent brain lesion (i.e. developmental phonagnosia). Based on the reviewed literature, we emphasise the need for a careful behavioural characterisation of phonagnosia cases by taking into consideration the multistage nature of voice-identity processing and the resulting behavioural phonagnosia subtypes.
Classification of Cardiac Arrhythmia using Hybrid Technology of Fast Discrete Stockwell-Transform (FDST) and Self Organising Map

Published: June 2018

The diagnosis of Cardio-Vascular diseases (CVD) is highly dependent on analysis of ECG signals. ECG analysis can be helpful in estimating the underlying cause and condition of heart in cardiac abnormality. The effectiveness of ECG signal analysis in detection of CVDs is widely accepted by professional healthcare service provider. Many algorithms have been proposed but almost all of them have some kind of limitations, and these limitations largely influence the effectiveness of ECG analysis. The performed research work is dedicated for design of unique self-organizing maps (SOMs) based neural network for classification of arrhythmia according to a particular ECG signal, the generation of SOMs is based on the certain unique signatures of ECG signals and have potential to classify different cardiac conditions. For extraction of unique features from ECG signals, we have proposed to use Fast Discrete Stockwell Transform (FDST). Since the proposed technique is a result of combining two different techniques hence called as hybrid technology. The purpose of using FDST is to identify unique signatures of ECG signals in a more improved manner than existing one, the term improved is used because it has several advantages over existing techniques such as wavelet and Fourier Transform based methods. Results obtained from the implementation of the technique are capable in visualizing the ECG sinus rhythm and arrhythmia conditions in form of unique SOM for each associated arrhythmia condition. This unique SOM based classification makes them ideal for being used as a diagnostic tool. This ability of arrhythmia classification using FDST and SOMs makes the technique unique and useful providing valuable information about patient condition. Using proposed technology a portable diagnosis tool for monitoring of patient at their site may be facilitated later, that will improve the quality of life of the patient by diagnosing cardiac condition.

Published: June 2018

A series of precise data consisting of zircon U–Pb ages, whole-rock geochemistry and Sr–Nd–Hf isotope compositions from the Huhetaoergai granitic pluton was collected in this study and combined with data from the western Huhetaoergai, Zhuxiaogubuhe and Yagan granitic plutons to constrain the petrogenesis and tectonic setting of granitic plutons in the northern Ya-Gan fault zone, North Alxa, China. The Huhetaoergai pluton is composed of hornblende diorite, medium- to coarse-grained biotite adamellite and coarse-grained biotite adamellite with K-feldspar megacrysts. The U–Pb zircon ages of biotite adamellite are 220.5 ± 1.9 Ma and 226.5 ± 2.4 Ma. These granitoids are I-type granites with highly radiogenic initial 87Sr/86Sr of 0.708085–0.735470, negative eNd(t) average values of −2.98–3.23 and high eHf(t) of 9–11.05. These features indicate the granitoids were formed from magmas generated from juvenile crust. We speculate that the granitoids of the Huhetaoergai pluton were emplaced during an episode of intense intraplate orogenic movement evolution in an extrusional setting after a period of extensional postcollisional intraplate evolution.

Published: June 2018

Parkia biglobosa (African locust bean) seed was fermented aerobically to produce a vegetable protein based condiment using various temperature differences and ambient temperature. The rate of fermentation was monitored using three (3) different methods namely: weight loss, pH and Carbon dioxide release. Samples were inoculated using Bacillus subtilis and Saccharomyces cerevisiae as starter culture. During fermentation, several changes occur in the seeds of the African Locust bean. The difference in the weight loss (initial and final weight of the fermenting samples) were used to monitor the rate of fermentation of the African Locust bean (parkia biglobosa) seeds to vegetable protein called ‘Iru’. Fermentation of this seed to ‘Iru’ is an alkaline fermentation, which was confirmed by this work. As means of monitoring the rate of fermentation, the evolution of CO2 was also monitored.

La vinculación que se establece entre el marquesado de Priego y el convento de Santa Clara de Montilla queda reflejada, entre otras facetas, en la relevancia que adquirieron algunas de sus religiosas, las cuales pertenecieron o fueron cercanas a esta familia nobiliaria. Es el caso de sor Ana de la Cruz Ribera, sobrina de los V marqueses de Priego, cuya vida en religión destacó por su extraordinaria observancia y misticismo. Su devoción a la Pasión de Cristo quedó ejemplificada en una imagen de crucificado que le donó su hermano fray Payo Afán de Ribera, de la orden de San Agustín. En recuerdo a su santidad se construyó una capilla en la clausura del convento de las clarisas de Montilla, cuyo estudio artístico se expone en este trabajo.
Influence of Crack on Modal Parameters of Cantilever Beam Using Experimental Modal Analysis
Authors: Chinka Siva Sankara Babu , Adavi Balakrishna , Putti Srinivasa Rao
Published: June 2018

In this paper, the dynamic behavior of a cantilever beam without and with crack is observed. An elastic Aluminum cantilever beams having surface crack at various crack positions are considered to analyze dynamically. Crack depth, crack length and crack location are the foremost parameters for describing the health condition of beam in terms of modal parameters such as natural frequency, mode shape and damping ratio. It is crucial to study the influence of crack depth and crack location on modal parameters of the beam for the decent performance and its safety. Crack or damage of structure causes a reduction in stiffness, an intrinsic reduction in resonant frequencies, variation of damping ratios and mode shapes. The broad examination of cantilever beam without crack and with crack has been done using Numerical analysis (Ansys18.0) and experimental modal analysis. To observe the exact higher modes of beam, discretize the beam into small elements. An experimental set up was established for cantilever beam having crack and it was excited by an impact hammer and finally the response was obtained using PCB accelerometer with the help sound and vibration toolkit of NI Lab-view. After obtaining the Frequency response functions (FRFs), the natural frequencies of beam are estimated using peak search method. The effectiveness of experimental modal analysis in terms of natural frequency is validated with numerical analysis results. This paper contains the study of free vibration analysis under the influence of crack at different points along the length of the beam.
The Inhomogeneous Gaussian Free Field, with application to ground state correlations of trapped 1d Bose gases
Authors: Brun Yannis , Dubail Jerome
Published: June 2018

This formalism is then applied to the study of ground state
correlations of the Lieb-Liniger gas trapped in an external potential
V(x)V(x).
Relations with previous works on inhomogeneous Luttinger liquids are
discussed. The main innovation here is in the identification of local
observables \hat{O} (x)Ô(x)
in the microscopic model with their field theory counterparts
\partial_x h, e^{i h(x)}, e^{-i h(x)}∂xh,eih(x),e−ih(x),
etc., which involve non-universal coefficients that themselves depend on
position — a fact that, to the best of our knowledge, was overlooked in
previous works on correlation functions of inhomogeneous Luttinger
liquids —, and that can be calculated thanks to Bethe Ansatz form
factors formulae available for the homogeneous Lieb-Liniger model.
Combining those position-dependent coefficients with the correlation
functions of the IGFF, ground state correlation functions of the trapped
gas are obtained. Numerical checks from DMRG are provided for
density-density correlations and for the one-particle density matrix,
showing excellent agreement.
International postgraduate students’ perceptions of service quality
Authors: Chaguluka Chancy , Beharry-Ramraj Andrisha , Amolo John
Published: June 2018

South African universities have embraced a drive to internationalize in view of globalization. One of the widely adopted measures towards internationalization has been the recruitment of international postgraduate scholars. The rationale is to draw diverse knowledge and expertise from the international students. However, the University of KwaZulu Natal’s Westville campus has not managed to attract a significant number of international scholars. The trend suggests that the university is unable to meet the expectations of international postgraduate students with regards to service delivery. The suggestion is premised on the argument that the previous and current international postgraduate students have not been satisfied with the service quality to stimulate other foreign postgraduate student enrolments through positive word of mouth. The main objective of the study was to confirm the assertions while exposing the gaps between their expectations and perceptions of service delivery at the university. The SERVQUAL model was used to guide the assessment of service quality among the research participants. The study adopted quantitative methodologies and data was drawn from international postgraduate students who were enrolled at the institution during the academic year 2016. The findings revealed that the international postgraduate students were dissatisfied with the levels of service at the university. Specifically, the study exposed gaps across all the five dimensions of service quality, namely reliability, responsiveness, assurance, empathy and tangibles. It was concluded that the management at the university should institute deliberate measures to improve service quality, especially towards international postgraduate students.

Published: June 2018

The objective of study was to assess and evaluate factors that affect entrepreneurial activities carried out by formal and informal migrant entrepreneurs from Ethiopia who conduct business operations in the nine provinces of South Africa. The study was descriptive and exploratory in nature. The design of the study was descriptive and cross-sectional. Data were collected from a stratified random sample of 3,045 migrant entrepreneurs from Ethiopia who conduct business in the nine provinces of South Africa. Stratified random sampling was used for the selection of eligible entrepreneurs. The study found that about 76% of businesses operated by migrant entrepreneurs from Ethiopia were profitable, whereas the remaining 24% of businesses were not profitable. About 32% of entrepreneurs were attracted to South Africa due to better infrastructural facilities. About 25% of entrepreneurs were attracted to South Africa due to better socioeconomic conditions. About 78% of migrant entrepreneurs had conducted business in South Africa for five years or more at the time of data collection. About 34% of businesses paid tax to the South African Revenue Service (SARS) on a regular basis. About 38% of businesses employed at least one South African in their businesses. About 85% of entrepreneurs stated that they had good working relationships with members of the various local communities in South Africa.

The aim of the research was to determine the influence of the substrate and different drainage materials on retention capacity and runoff water quality from three green roof containers. Phosphates were chosen as the water quality indicator based on their potential adverse impact on water quality in urban rainwater collectors. The field experiment was conducted at the Warsaw University of Life Sciences Water Center meteorological station in years 2013–2015. In terms of precipitation, the monitoring period covered a wet (+147.1 mm), average (+42.7 mm) and dry (− 66.3 mm) year. Leakage from the containers was recorded when the substrate moisture exceeded 20% and precipitation exceeded 3.5 mm/d for washed gravel, or 5.0 mm/d for a polypropylene mat and expanded clay. Phosphates were observed in leachates from all containers, with higher values observed in the second year of monitoring. As the result of this study, it can be concluded that the polypropylene mat and aggregates create different conditions for the formation of the leachate, in both volumes and its chemistry. The drainage layer made from a polypropylene mat is the most effective in terms of rainwater retention capacity and the resulting leachate quality.

Published: June 2018

Hemocyanins are large and versatile glycoproteins performing various immunological
and biological functions in many marine invertebrates including arthropods and
molluscs. This review discusses the various pharmacological applications of mollusc hemocyanin
such as antiviral activity, immunostimulatory and anticancer properties that
have been reported in the literature between the years 2000 and 2016. Emphasis is placed
on a better mechanistic understanding of hemocyanin as a therapeutic agent. Elucidation
of the mechanism of action is essential to improve the clinical efficacy and for a better
understanding of some endogenous immunological functions of this complex glycoprotein.

Published: June 2018

Background:

Phenstatin and their derivatives display remarkable antiproliferative
activity toward a wide variety of preclinical tumor models. Structural simplicity and
excellent stability of phenstatins offer a stimulating premise for developing various derivatives
with profound antimitotic activity and excellent cytotoxicity.

Objective:

To do analysis of literature that phenstatins derivatives inhibit tubulin
polymerization through their interaction at the colchicine binding site of microtubules and
arrest the G2/M phase of the cell cycle. In addition, phenstatin derivatives are undergoing
clinical evaluation as vascular targeting/disrupting agents and also exhibit direct antiangiogenic
properties.

Methods:

An organised well designed and appropriately managed search of bibliographic
databases for peer-reviewed research literature using a focused review question and inclusion/
exclusion criteria has been done for this article.

Conclusion:

In this review article, the synthesis and structure-activity relationships of
phenstatin and a wide number of their reported analogues with modifications to ring A,
ring B, and to the keto position are discussed in the perspective of medicinal chemistry
with proper conclusion.
Coronary Microvascular and Cardiac Dysfunction Due to Homocysteine Pathometabolism; A Complex Therapeutic Design
Authors: Koller Akos , Szenasi Annamaria , Dornyei Gabriella , Kovacs Nora , Lelbach Adam , Kovacs Imre
Published: June 2018

In various metabolic diseases, both the coronary circulation and cardiac metabolism are altered. Here
we summarize the effects of a condition called hyperhomocysteinemia (HHcy) - which can develop due to genetic
and/or environmental causes - on the function of coronary microvessels and heart. This metabolic disease is underappreciated,
yet even mild or moderate elevation of plasma concentrations of homocystein (Hcy, plasma Hcy
>16 µM), a sulfur-containing amino acid produced via methionine metabolism) leads to coronary and peripheral
artery and even venous vessel diseases, eliciting vasomotor dysfunction and increased thrombosis, consequently
increased morbidity and mortality. Yet the underlying mechanisms have not yet been revealed. Recent studies
indicated that there are common pathomechanisms, which may affect several cellular functions. With methionin
diet-induced HHcy two main pathomechanisms were revealed: the dysfunction of nitric oxide (NO) pathway
resulting in reduced dilator responses of arteries and arterioles, and the simultaneously increased thromboxane A2
(TXA2) activity both in vessels and platelets. These changes are likely due to an increased production of reactive
oxidative species (oxidative stress) due to increased NADPH oxidase assembly, which eventually lead to inflammatory
processes (indicated by increases in TNFα, NFκbeta, p22phox, p67phox, and rac-1, levels) and changes in
various gene expressions and morphological remodeling of vessels. Increased superoxide production and reduced
availability of NO alter the regulation of mitochondrial function in the myocardium. The interactions of these
pathomechanisms may explain why HHcy increases the uptake of glucose and lactate and decreases the uptake of
free fatty acid by the heart. The pathological consequences of HHcy could be worsening by the simultaneous
presence of other risk factors, such as hyperlipidemia, diabetes mellitus and metabolic syndrome. All in all, HHcy
and associated pathometabolism lead to severe changes and dysfunctions of coronary arterial vessels and cardiac
function, which may not always be apparent in clinical settings but most likely contribute to the increased prevalence
of cardiovascular diseases and mortality, which however can be reduced by appropriate prevention and
treatments. We believe that HHcy is an underestimated - likely due to inappropriate clinical trials - but serious
disease condition because it promotes the development of atherosclerosis in large arterial vessels, vasomotor
dysfunction in microvessels, hypertension and thrombosis. In this review, we will summarize previous functional
findings focusing on coronary vessels and cardiac function and the underlying cellular and molecular mechanisms
enabling the development of novel treatments.

Published: June 2018

BACKGROUND

Collecting patient-reported outcome (PRO) data systematically enables objective evaluation of treatment and its related outcomes. Using disease-specific questionnaires developed by the International Consortium for Health Outcome Measurement (ICHOM) allows for comparison between physicians, hospitals, and even different countries.

OBJECTIVE

This pilot project aimed to establish a digital system to measure PROs for new patients with breast cancer who attended the Charité Breast Center This approach should serve as a blueprint to further expand the PRO measurement to other disease entities and departments.

METHODS

In November 2016, we implemented a Web-based system to collect PRO data at Charité Breast Center using the ICHOM dataset. All new patients at the Breast Center were enrolled and answered a predefined set of questions using a tablet computer. Once they started their treatment at Charité, automated emails were sent to the patients at predefined treatment points. Those emails contained a Web-based link through which they could access and answer questionnaires.

RESULTS

By now, 541 patients have been enrolled and 2470 questionnaires initiated. Overall, 9.4% (51/541) of the patients were under the age of 40 years, 49.7% (269/541) between 40 and 60 years, 39.6% (214/541) between 60 and 80 years, and 1.3% (7/541) over the age of 80 years. The average return rate of questionnaires was 67.0%. When asked about the preference regarding paper versus Web-based questionnaires, 6.0% (8/134) of the patients between 50 and 60 years, 6.0% (9/150) between 60 and 70 years, and 12.7% (9/71) over the age of 70 years preferred paper versions.

CONCLUSIONS

Measuring PRO in patients with breast cancer in an automated electronic version is possible across all age ranges while simultaneously achieving a high return rate.

Este estudio presenta el análisis del repositorio institucional de la Universidad Federal de Brasilia, objetivando verificar si éste emplea los principios propuestos por Morville y Rosenfeld. El repositorio analizado presenta compatibilidad con algunos principios, si bien necesita solucionar deficiencias referentes al sistema de búsqueda, accesibilidad y atención de las demandas de los usuarios.
Acumulación de capital y crecimiento estatal en México: un análisis con datos panel
Authors: Rodríguez Benavides Domingo , Mendoza Miguel Ángel , Martínez Miguel Ángel
Published: June 2018

En el presente texto se estudia el vínculo entre el crecimiento económico y
la acumulación del stock de capital industrial estatal mediante técnicas de panel, en el
periodo 1960-2012. El análisis se efectúa sobre dos momentos: el de industrialización
nacional (1960-1982) y el de las reformas estructurales (1983-2012). Los resultados
muestran una relación de largo plazo en ambos periodos, pero con el signo opuesto al
esperado en el último, lo cual sugiere que la desaceleración del capital industrial puede explicar la ralentización del crecimiento en las últimas tres décadas. Este resultado se confirma con la caída de la manufactura, así como de otros indicadores económicos. Los resultados de las pruebas de causalidad muestran bidireccionalidad entre ambas variables, evidenciando así un círculo virtuoso entre crecimiento y acumulación.
Impacto de la ImperIal Germany de Veblen en los enfoques estructuralistas y de la teoría de la dependencia
Authors: Baca William
Published: June 2018

El presente artículo identifica puntos en común y diferencias entre el estructuralismo latinoamericano, la teoría de la dependencia y el texto Imperial Germany (1915) de Thorstein Veblen. Se explora la conexión en aspectos tales como dependencia en el sendero, tecnología y política económica. Imperial Germany se asemeja a varias de las principales recomendaciones de políticas de los estructuralistas y teóricos de la dependencia. Empero, el estructuralismo está más cercano a las ideas de los institucionalistas y del mismo Veblen. En conclusión, estructuralistas y la versión de Veblen en Imperial Germany concuerdan en que una política industrial debe ser guiada por el gobierno, aunque  Veblen y los institucionalistas claramente presentan el cambio social mediante mejoras tecnológicas, algo que el estructuralismo no describe.
Rendición de cuentas y destino de la deuda pública del gobierno de la Ciudad de México
Authors: Astudillo Marcela , Porras Raúl
Published: June 2018

Resumen. El presente trabajo explora la rendición de cuentas del Gobierno de la
Ciudad de México respecto a su deuda pública durante el periodo 1999-2015. Las
preguntas planteadas son: ¿a qué proyectos se destinan los recursos provenientes de
deuda pública? ¿La rendición de cuentas permite evaluar los proyectos financiados con deuda pública? A pesar de que la legislación establece la obligación de transparentar el destino de la deuda, se evidenció una rendición de cuentas parcial en todas las modalidades de financiamiento como: banca privada, de desarrollo, Mercado de Valores y Asociaciones Público-Privadas (APP). Además, la opacidad es total en cuanto a la evaluación de los resultados obtenidos. Mediante una prueba de cointegración de la deuda e inversión pública se puede afirmar que la deuda pública total tiene cierto efecto en el comportamiento de la inversión pública de la Ciudad de México.
