Authors: Kahlmann Willi , Poremba Emanuel , Potyagaylo Danila , Dössel Olaf , Loewe Axel
Published: September 2017

The Purkinje system is part of the fast-conducting ventricular excitation system. The anatomy of the Purkinje system varies from person to person and imposes a unique excitation pattern on the ventricular myocardium, which defines the morphology of the QRS complex of the ECG to a large degree. While it cannot be imaged in-vivo, it plays an important role for personalizing computer simulations of cardiac electrophysiology. Here, we present a new method to automatically model and customize the Purkinje system based on the measured electrocardiogram (ECG) of a patient. A graphbased algorithm was developed to generate Purkinje systems based on the parameters fibre density, minimal distance from the atrium, conduction velocity, and position and timing of excitation sources mimicking the bundle branches. Based on the resulting stimulation profile, the activation times of the ventricles were calculated using the fast marching approach. Predescribed action potentials and a finite element lead field matrix were employed to obtain surface ECG signals. The root mean square error (RMSE) between the simulated and measured QRS complexes of the ECGs was used as cost function to perform optimization of the Purkinje parameters. One complete evaluation from Purkinje tree generation to the simulated ECG could be computed in about 10 seconds on a standard desktop computer. The measured ECG of the patient used to build the anatomical model was matched via parallel simplex optimization with a remaining RMSE of 4.05 mV in about 16 hours. The approach presented here allows to tailor the structure of the Purkinje system through the measured ECG in a patient-specific way. The computationally efficient implementation facilitates global optimization.

Published: September 2017

The main goal of this research is modeling and simulation of ethylene production through naphtha thermal cracking in a coil furnace reactor. The naphtha cracking and decoking processes are modeled based on the mass, energy and momentum balance equations considering a detail kinetic model at pseudo-dynamic condition. To develop a reliable and applicable model, a detail thermal model is considered to predict tube skin temperature. To prove accuracy of developed model and considered assumptions, the simulation results are compared with the plant data. In addition, the results of coke burning in the decoking cycle by mixture of air and steam are presented. It is appeared that ethylene production decreases during the process run time gradually. The simulation results proved that increasing feed temperature, feed pressure and combustion chamber temperature during the process run time is a practical solution to maintain production capacity at an acceptable level. Finally, the optimal operating condition of thermal cracking process is calculated during the process run time based on the time variant feeding policy to achieve maximum ethylene production capacity. It is appeared that applying optimal condition on the system could increase ethylene production capacity from 15.31 ton.h‒1 to 15.49 ton.h‒1.
A New Approach Towards Life Prediction of Case Hardened Bearing Steels Subjected to Rolling Contact Fatigue
Authors: Bhattacharyya Abir , Londhe Nikhil , Arakere Nagaraj , Subhash Ghatu
Published: September 2017

The failure of a bearing-raceway assembly is governed by the spatial distribution of subsurface stresses at the vicinity of a bearing-raceway contact and the evolution of these stresses during rolling contact fatigue (RCF) loading. In this paper, we propose an experimental methodology that allows one to accurately measure the location and magnitude of the cyclically evolving elastoplastic von Mises stresses in terms of microhardness numbers. An M50NiL steel rod is subjected to RCF by three silicon nitride (Si3N4) balls for over several hundred million cycles at 5.5 GPa contact stress level. Microindentation hardness measurements within the subsurface RCF-affected regions of the rod revealed significant material hardening. A mechanistic methodology to construct a stress-life (S-N) diagram for RCF loading is proposed. S-N diagrams are constructed based on maximum von Mises stress amplitude and volume average von Mises stress amplitude. The effects of elastic modulus and yield strength gradient on stress fields are also considered in this analysis. Comparison of S-N diagrams based on both stress amplitudes indicates that the maximum von Mises stress amplitude overpredicts the fatigue strength of material in S-N diagrams. The experimental results obtained by following this methodology can help construct material hardening models for RCF, which may lead to an improved estimate of bearing fatigue life.
A Classroom Simulation Activity to Visualize Energy and Matter Transformation in Cellular Respiration and Photosynthesis
Authors: Svec Lace A.
Published: September 2017

Undergraduate introductory biology students at the university level often struggle to trace movement of matter and energy through catabolic and anabolic processes in biological systems. A sequential guided simulation of cellular respiration and photosynthesis provides students an opportunity to actively model and visualize matter transformation and energy accumulation and degradation through the movement of molecular and energy “game pieces.” The activity was designed to help students generate a simplified outline of these two highly complex processes, while reinforcing the principles of conservation of matter and energy. My students participated in this activity during peer-led review sessions in an undergraduate, introductory, majors biology course (ca.150 students in 18 SI sessions over two semesters), but instructors could also easily adapt it for use in small lecture or laboratory classrooms, introductory cell biology, physiology, and ecology courses, or with high school students.
Salamander Antipredator Defenses: A Field Exercise to Engage Students in Ecosystem Dynamics
Authors: Connelly Sandra J. , Meier Katelyn , Becker Madeline
Published: September 2017

The addition of field experimentation to the theory of behavioral biology and ecosystem science creates a significant critical thinking link for students at all levels. First-hand observations of the responses of salamanders in the field permit students to see how organisms behave in their natural habitat. This exercise introduces students to the study of animal behavior, specifically the antipredator responses of salamanders. The students form hypotheses regarding the behavior of salamanders in their natural environment and then record responses of individual salamanders, compile data, interpret data, and draw conclusions about the behavior of salamanders in response to natural stressors.
Teaching Principles of Endocrinology Using the Tobacco Hornworm
Authors: Rowland John M. , Rowland Ian J. , Goodman Walter G.
Published: September 2017

Insects provide an excellent model for examining concepts in endocrinology in the classroom. They are relatively inexpensive to rear, short-lived, and free from animal welfare regulations. Using the tobacco hornworm (Manduca sexta) as a model, we have developed a simple laboratory experiment to demonstrate the role of hormones in development. In this experiment, students will use a readily available agonist to disrupt insect development, preventing metamorphosis. This exercise fits well into the AP lab curriculum and the NGSS LSB.1 objectives.
Extended Synaptotagmin Localizes to Presynaptic ER and Promotes Neurotransmission and Synaptic Growth inDrosophila

In highly polarized neurons, an extensive endoplasmic reticulum (ER) network extends to distal dendrites and axons. Several human diseases result from...

The endoplasmic reticulum (ER) is an extensive organelle in neurons with important roles at synapses including the regulation of cytosolic Ca2+, neurotransmission, lipid metabolism, and membrane trafficking. Despite intriguing evidence for these crucial functions, how the presynaptic ER influences synaptic physiology remains enigmatic. To gain insight into this question, we have generated and characterized mutations in the single extended synaptotagmin (Esyt) ortholog in Drosophila melanogaster. Esyts are evolutionarily conserved ER proteins with Ca2+-sensing domains that have recently been shown to orchestrate membrane tethering and lipid exchange between the ER and plasma membrane. We first demonstrate that Esyt localizes to presynaptic ER structures at the neuromuscular junction. Next, we show that synaptic growth, structure, and homeostatic plasticity are surprisingly unperturbed at synapses lacking Esyt expression. However, neurotransmission is reduced in Esyt mutants, consistent with a presynaptic role in promoting neurotransmitter release. Finally, neuronal overexpression of Esyt enhances synaptic growth and the sustainment of the vesicle pool during intense activity, suggesting that increased Esyt levels may modulate the membrane trafficking and/or resting Ca2+ pathways that control synapse extension. Thus, we identify Esyt as a presynaptic ER protein that can promote neurotransmission and synaptic growth, revealing the first in vivo neuronal functions of this conserved gene family.

Religijos prievarta? Nuo sakralumo prie šventumo
Authors: Ciancio Claudio
Published: September 2017

Religija visuomet priklauso reiškiniams, labiausiai kaltinamiems socialine ir politine prievarta. Iš tiesų, religija gali reikštis kaip netolerancija ir prievarta, ir tai įvyksta, kai dieviškumas yra suobjek­tinamas, kitaip tariant, kai jis pasilieka sakralumo formos. Neneigiant simbolinio religijos matmens, būtina išgryninti religiją, kad ji pasiektų dieviškumą šventumo forma, kurioje dieviškumas prieina­mas kaip absoliuti transcendencija ir absoliuti imanencija. Ši tezė straipsnyje iliustruojama pasitel­kiant religinės šventės interpretaciją ir Antonello da Messinos paveikslo Apreiškimas Švenčiausiajai Mergelei Marijai analizę.

Remiantis archyvinių dokumentų, susijusių su A. Mickevičiaus gatvėje Nr. 19 (Kaune) tarpukariu Feigės ir Nisono Mislerių valdoje buvusiais pastatais, duomenimis, ir vietos tyrimu dabartinėje šios valdos teritorijoje, straipsnyje argumentuojama, kad pastatas, kuriame bent nuo 1936 m. iki Antrojo pasaulinio karo pradžios gyveno Emmanuelio Levino tėvai, turėtų būti A. Mickevičiaus g. 27 D. Antroje straipsnio dalyje pateikiami ir nagrinėjami Kauno miesto apskrities mokesčių inspekcijos dokumentai (1936–1939 m.), susiję su Emmanuelio Levino tėvo Jechielio Levino popieriaus parduotuve (sankrova, krautuve). Dokumentai rodo, kad popieriaus parduotuvė buvo nedidelė (įsikūrusi tik vienoje nedidelėje patalpoje, neturėjo sandėlio, samdė vieną aptarnaujantį pagalbininką), apyvarta buvo menka, nors mokesčių tarnybos kasmet darydavo išvadą, jog apyvarta kyla, ir keldavo mokesčių procento lygį, argumentuodamos, kad įmonė sena ir turi nuolatinę klientūrą. Ir nors Jechieliui Levinui dvejus metus pavyko pasiekti, kad būtų pripažinta 1934 m. apyvartos apimtis, 1939 m. to padaryti nebepavyko. Jechielis Levinas protestuose, rašytuose atsakingoms mokesčių institucijoms, vis skundėsi, kad verslas smunka, o ne kyla, ir kad didėjantys mokesčiai gali jį visiškai sužlugdyti.

Pesut atau Irrawaddy dolphin (Orcaella brevirostris) merupakan salah satu spesies mamalia air yang populasinya semakin terancam. Sedikitnya informasi keberadaan pesut di Kalimantan Barat, menyebabkan upaya konservasi dan pengelolaannya belum optimal. Tulisan ini bertujuan untuk mengetahui keberadaan dan tingkah laku pesut yang terdapat di perairan Kubu Raya dan Kayong Utara, Kalimantan Barat. Kegiatan pengamatan menggunakan metode jelajah dengan bantuan teropong binokuler dilaksanakan pada bulan April2013. Selama pengamatan hanya diketahui terdapat satu kelompok pesut sebanyak 4-6 individu yang terdiri dari pesut muda dan dewasa. Kelompokan itu dijumpai di muara Sungai Bumbun pada kedalamanan perairan 11 meter. Tingkah laku yang teramati menunjukkan gerombolan pesut umumnya memburu kelompokan ikan dan sesekali menyemburkan air dari blowhole nya. Berdasarkan ciri-ciri morfologi dan tingkah laku yang teramati serta kondisi lingkungan perairan setempat maka perairan di Kabupaten Kubu Raya dan Kabupaten Kayong Utara yang terletak di Provinsi Kalimantan Barat diduga merupakan perairan yang potensial sebagai habitat pesut (Orcaella brevirostris).Irrawaddy dolphins (Orcaella brevirostris (Owen in Gray 1866)) is one of aquatic mammals species who populations are increasingly threatened.

Komposisi hasil tangkapan ikan berparuh (Istiophoridae dan Xiphiidae) menduduki peringkat kedua terbesar setelah tuna (Thunnus sp.) pada perikanan rawai tuna. Sekitar 90% jenis ikan berparuh yang di daratkan didominasi oleh ikan pedang (Xiphias gladius), yang mana merupakan hasil tangkap sampingan dari perikanan rawai tuna, terutama di Samudera Hindia bagian timur. Meskipun dikategorikan sebagai ikan dengan nilai ekonomis tinggi, akan tetapi studi mengenai parameter populasi untuk spesies ini masih terbatas, terutama di Indonesia. Penelitian ini bertujuan untuk menduga parameter pertumbuhan, laju mortalitas dan laju ekploitasi ikan pedang berdasarkan data ukuran panjang. Model pengkajian stok menggunakan data frekuensi panjang dipilih karena ketersediaan dan kemudahan pengambilan data tersebut dibandingkan dengan metode lainnya. Penelitian ini menggunakan data pemantau ilmiah tahun 2005 sampai dengan 2014 dan data pengamatan harian pendaratan tuna dan sejenisnya tahun 2002 sampai dengan 2014 di Samudera Hindia. Hasil penelitian menunjukkan pertumbuhan ikan pedang relatif cepat, terutama pada awal masa pertumbuhan dengan nilai K = 0,12/tahun, t0 = -0,76025 tahun dan L = 302,4 cmFL. Nilai F (0,28/tahun) sedikit lebih besar daripada nilai M (0,24/tahun), yang berarti kematian ikan pedang lebih banyak disebabkan oleh penangkapan. Nilai E sebesar 0,55 mengindikasikan bahwa ikan pedang yang tertangkap oleh armada rawai tuna di Samudera Hindia berada pada kondisi optimum. Billfishes (Istiophoridae and Xiphiidae) are the second largest catch in tuna longline fisheries. About 90% of billfishes landed dominated by swordfish (Xiphias gladius) which was a by-catch from tuna longline fisheries, especially in eastern Indian Ocean. Despite of its high economic value, study on stock assessment for this species is limited, especially in Indonesia. The catch-at-size based stock assessment model was applied, to its availability and ease on collecting the data. The Objectives of this study are to estimate growth parameter, mortality rate and exploitation rate based on catch-at-size data. The primary data was obtained from scientific observer program from 2005 to 2014 and port sampling data from 2002 to 2014. The result showed that swordfish were relatively fast growth, especially on their early age (K = 0.12/year) with t0 estimated around -0.76 year and Linf about 302.4 cmLJFL. The estimated of total mortality (Z), natural mortality (M) and fishing mortality (F) from the model were 0.52/year, 0.24/year and 0.28/year respectively. The explitation rate of swordfish in the eastern Indian Ocean is on optimum level (E=0.55).
