Authors: Adair Carol , Darby Heather , Goeschel Tyler , Barbieri Lindsay , White Alissa
Published: November 2020

A research team at UVM, led by Dr. Carol Adair and Dr. Heather Darby, is evaluating the benefits and drawbacks of four different tillage approaches (conventional, strip, vertical, and no till) and two different methods of manure application (broadcast and injection). The goal is to determine the practices best suited for reducing greenhouse gas emission, improving carbon storage and limiting nitrogen losses. The team measures carbon dioxide and nitrous oxide emissions from the treatments every two weeks or more frequently after events (large rainfall, manure application) using a measuring device called photoacoustic multigas monitor.

Authors: Lima Rafaela Batista de , Amaral Camilla Lais , Minatti Jaqueline
Published: November 2020

It is known that collagen is a protein of great importance for bones, tendons, cartilage, muscles, skin, hair and nails. There are several types of collagen, and type II is the main component of the joint cartilage matrix and can help prolong the independent lifestyle of an elderly person, improving their quality of life. The research aimed to evaluate the effect of a collagen mix composed of peptides, type II collagen and nutrients involved in the joint bone metabolism of active elderly. Volunteers with a minimum age of 60 years and physically active participated in the research. This is a non-randomized clinical trial conducted with the gymnastics group of the elderly of an Activity Center in Florianópolis – SC. Oral supplementation with the collagen mix composed of bioactive peptides of hydrolyzed collagen, intact type II collagen, silicon and nutrients involved in joint bone metabolism (Duo flex®) was administered for 90 days, and the next 30-day cycle of the supplement was always delivered before the end of the current cycle, so that the participants did not interrupt the treatment. These were also followed weekly via telephone contact to avoid withdrawal or interruption of treatment. Questionnaires were applied to evaluate symptoms related to sarcopenia, joint functionalities, characteristic skin, nails and hair health, and anthropometric measurements. The sample consisted of 50 elderly, most of them female (72%). Product consumption reduced pain, decreased stiffness and improved joint mobility according to the WOMAC questionnaire result. Duo flex® has significantly improved joint health and therefore can be an effective solution to delay joint manifestations. The results suggest that collagen mix can be used as a therapeutic approach for physically active elderly.

Nomenclature survey of the genus Amaranthus (Amaranthaceae). 10. What is Amaranthus commutatus?
Authors: Iamonico Duilio
Published: November 2020

The name Amaranthus commutatus, originally validated by Kerner for a plant taxon from Hungary and Slovakia, was studied as part of a series of contributions with the final aim to clarify the complicated nomenclature of the genus Amaranthus. On the basis of the protologue, the name Amaranthus commutatus cannot be associated with any European species, while out of Europe, Kerner’s original data of A. commutatus may match the morphology of the Australian species A. rhombeus. Unfortunately, no original material has been traced so far and thus no lectotype can be designated (Arts. 9.3 and 9.4 of Shenzhen Code). Consequently, neotypification is desirable according to Art. 9.8. However no specimens of Amaranthus seen by Kerner have been traced and it was very difficult to understand Kerner’s concept of that taxon. Having no suitable specimens available, I prefer to avoid the designation of a neotype, and the possible synonymization of A. commutatus with A. rhombeus based just on Kerner’s data. Furthermore, the synonyms cited by Kerner in the protologue [Amaranthus blitum var. polygonoides (here lectotypified on a specimen preserved at K), and A. blitum var. prostratus (lectotype designated by Iamonico in 2016 on a Balbis’ illustration] refer to other species, i.e. A. albus (new proposed synonymy) and A. deflexus, respectively. The treatment of Amaranthus commutatus appears inconsistent but this fact is not ground for rejecting of the name since does not threat any other name and there are no disadvantageous nomenclatural changes (Art. 56.1). Since the failure to properly designate a type, and the impossibility to reject A. commutatus, Kerner’s name continues to be of ambiguous nature and is proposed as listed as a name incertae sedis.

To determine whether acutely-induced supraphysiological hyperinsulinemia influences brain metabolism in patients with type 1 diabetes (D) and healthy controls (C) as detected by MR Spectroscopy. Group D consisted of 4 patients with the average duration of diabetes for 7 years. They were matched according to age, sex and BMI to 4 healthy controls. 1H MR Spectroscopy was performed with a 1.5 Tesla. Spectra were obtained from parietooccipital white matter repeatedly during a 3-h hyperinsulinemic euglycemic clamp with 2 mU.kgˉ¹.minˉ¹. In group D, significantly lower basal concentrations of N-acetylaspartate (p=0.02), choline (p=0.03), creatine (p=0.002) and inositol (p=0.007) were detected compared to C. After the induction of hyperinsulinemia, concentrations of choline, creatine, GABA, inositol, lactate, NAA and composite signal glutamate + glutamine (Glx) stayed stable. The detection of glucose signal is less realiable at 1.5 Tesla but we registered the alteration in glucose concentration (p=0.003) in the whole group. Originally sightly elevated glucose concentration in D decreased on the contrary to the increase of originally lower glucose level in C. In conclusions, brain metabolism was altered in D. Short term supraphysiological euglycemic hyperinsulinemia induced changes in the concentration of brain glucose in both C and D.

Published: November 2020

Time delay in the mediation of ventilation (VE) by arterial CO2 pressure (PaCO2) was studied during recovery from short impulse-like exercises with different work loads of recovery. Subjects performed two tests including 10-s impulse like exercise with work load of 200 watts and 15-min recovery with 25 watts in test one and 50 watts in test two. VE, end tidal CO2 pressure (PETCO2) and heart rate (HR) were measured continuously during rest, warming up, exercise and recovery. PaCO2 was estimated from PETCO2 and tidal volume (VT). Results showed that predicted arterial CO2 pressure (PaCO2 pre) increased during recovery in both tests. In both tests, VE increased and peaked at the end of exercise. VE decreased in the first few seconds of recovery but started to increase again. The highest correlation coefficient between PaCO2 pre and VE was obtained in the time delay of 7 s (r=0.854) in test one and in time delays of 6 s (r=0.451) and 31 s (r=0.567) in test two. HR was significantly higher in test two than in test one. These results indicate that PaCO2 pre drives VE with a time delay and that higher work intensity induces a shorter time delay.

Authors: Mulyono Mulyono , Berchmans Hanny J
Published: November 2020

In common mini hydro power plants in Indonesia, the control of water levels in intake, sand-trap and head pond is carried out manually. This conventional manual control system may cause damages of waterway and all its components due to overflow or transient flow of water during load shedding or black out of electricity grid. The damages eventually may increase cost of maintenance and increase the risk of waterway collapse or excessive water hammer in penstock pipe. This type of collapses often happen in many mini hydro power plants in Indonesia. The risk of damages can be reduced by installing water level control and monitoring system in all key water way components such as in intake, sand-trap and head pond. Some other mini hydro power plants have installed water level control and monitoring system. But the price of such control system is still very expensive and high operation and maintenance cost. Thus, this thesis work designs and simulates simple and inexpensive the water level control and monitoring system for a mini hydro power plant. In this thesis work, the design and simulation of the water level control and monitoring system are carried out by a simulated three water tanks where the water levels in the tanks are monitored and controlled by using ultrasonic level sensors and motorized valves respectively. A simple and inexpensive Arduino based water level control and monitoring system is successfully designed to fulfil the requirement of quick or fast respond for water level control in the simulated model.

Diesel engines are the main components used in many sectors from automotive, industry to manufacturing. Diesel engines have many advantages including being able to produce large power on low engine turns. Diesel engines use diesel fuel. Where this diesel fuel must be ensured that it is always clean. So the role of the fuel filter is very important to ensure the performance of the diesel engine. The ability of the fuel filter will decrease in its function to filter out impurities in the fuel path. So that this fuel filter must be replaced periodically according to its operating hours. This tool is made to optimize the use of fuel filters in accordance with the conditions of the clogged. This tool will work to monitor the fuel filter clogged condition by calculating the pressure read by the controller before and after passing the fuel filter. If the clogged has reached 70%, the controller will automatically activate the solenoid valve to change the use of the fuel filter from the main fuel filter to the backup fuel filter. So that in this way the use of the fuel filter will be more optimal in accordance with the actual conditions of the clogged.

Prototype Design of Golf Swing Speed Detection Mobile Application (GSSDMA)/Swing Vision (SV) has been researched and developed on this thesis with computer vision technique. Frames detection method has been implemented to performed calculation of the swing speed by manually identification of the frames from start of down swing to impact of the ball with Matlab Video Viewer as initial reference calculation, when head of golf club start to move to downswing as frame-zero/fr0 and frame-n/frn as end of the frame after the head of golf club impact to the ball and then the total frames can be determined by frn minus fr0 (frn - fr0) which will be used for speed calculation reference formula using Python programming.Both measurements have been recorded using RADAR and accelerometer systems to get references of swing speed data measurement from some golfers in golf driving ranges. Accelerometer data measurements have been selected to use as reference of speed calculation with Python programming for software application development since deviation standard is lower than the RADAR systems.There is a limitation on the hand phone camera speed which only have thirty frames per second (30 fps) and the maximum swing speed can be tested with this camera is 101,2 mph at the moment which has three frames (frn-fr0). Found a swing speed formula y = - 0,53x3 + 9,53x2 – 61,27x + 213,35 from experimental data’s of Driver, 6 Iron, 8 Iron and Pitching and maximum swing speed can be predicted is 124,69 mph which has two frames.
ANALYSIS OF MOTOR SPEED EFFECT ON WINDING TENSION IN THE WIND UP CALENDERING PROCESS
Authors: Sugiyarto Sugiyarto , Setiawan Widi
Published: November 2020

The winding process is widely used in manufacturing industries. For the high speed winding, the centre winding method is used. Irregular internal stresses at the centre of the roll result in major weaknesses such as buckling, spoking and cinching. Therefore, entanglement with the right tension is very important to get a stable wound package. It should be mentioned that winders usually operate based on the principle of precision winding. A typical characteristic of winders is increasing the surface speed as the diameter increases. This will cause the winding to increase which has the potential to cause damage. To overcome damage due to an increase in roll tension, the rolling motor speed must decrease so that the roll tension remains the same or even decreases. And because the rolling process uses additional media in the form of a liner fabric which is tension controlled with pneumatic disc brake, the pressure brake must also be made taper constructing both.

Az irányelvek betartása létkérdés minden hypertoniás beteg számára, ennek ellenére még a gazdasági szempontból fejlett országokban sem kielégítô a jól kontrollált hypertoniások aránya. Földünk öt kontinensén az irányelvek sajnos több szempontból is eltérô vagy nagyon eltérô javaslatokat adnak a vérnyomás mérése, a diagnózis felállítása, a cardio­vascularis kockázat becslése, a célérték meghatározása vonatkozásában, bár az utóbbi években bizonyos területeken megindult a „konszenzusra” irányuló törekvés. Közleményünkben ezeket a különbözô véleményeket és állásfoglalásokat kívánjuk bemutatni az ACC/AHA, az ESC/ESH, a NICE, a kanadai és az ausztrál irányelvek elemzésével. Figyelembe vettük a WHO és az ISH állásfoglalásait is. Leírjuk az irányelvekben észlelhetô elvi és gyakorlati közeledéseket és a már megvalósult konszenzusokat.
‘THE TOWN, THE TOWN, GOOD PIT, HAS ASSES EARS!’: Unstable Audiences in Della Cruscan Poetic Conversation
Authors: Holdway Katie
Published: November 2020

In his famously disparaging poetic retorts to the poetry of the British Della Cruscan movement, the Baviad and Mæviad, Tory satirist William Gifford made every effort to separate the readers of Della Cruscan poetry into two distinct audiences: Della Cruscan ‘writer-readers’ who read and actively responded to pieces written by other members of the coterie with poetry of their own, and the non-participating mass audience. According to Gifford, this latter audience – metonymized as ‘the Town’ in the Baviad – ignorantly follows the whims of fashion, absorbing Della Cruscan poetry, but never actually responding to it. Through an analysis of both Della Cruscan poetry and Gifford's retorts, this essay aims to re-establish the links between these two kinds of audiences. I will argue that Gifford's attempts to suppress these links stemmed from a deep-seated fear – fuelled by post-Revolutionary political instability – that the Della Cruscan coterie offered a platform whereby members of the mass reading audience could join their poetic conversations pseudonymously, and ultimately be granted a voice, regardless of their gender or political affiliations.
The Riddles of Mazeppa; or, More Questions than Answers: Watermarks and Cohabitations, April 1817–September 1818
Authors: Lansdown Richard
Published: November 2020

Byron's Mazeppa is an unusual case in his writing career. He was generally a quick writer, but this poem – an important link between his earlier melodramatic tales and his later comic ones – was started in April 1817 and completed only in September 1818, nearly eighteen months later. This essay uses various forms of evidence, in particular literary allusion and the various paper stocks on which the poem was drafted, to suggest when and where the poem was ‘broken off’ before being finally completed. It also considers in the poem in the light of other works written during the period ( The Lament of Tasso, Manfred, Childe Harold IV, Beppo, and Don Juan) before considering its overall theme in contrast to Voltaire's History of Charles XII.
Directing the ‘Unfinished Scene’: Utopia and the Role of the Poet in Shelley's Hellas
Authors: Quayle Jonathan
Published: November 2020

Hellas; A Lyrical Drama (1822) reveals profound tensions in Shelley's thinking about the role that poets play in writing the future. In the Preface, Shelley invokes his ‘poet's privilege’ to imagine the outcome of the ‘unfinished scene’ – the ongoing Greek War of Independence – but the final chorus, which begins by triumphantly announcing the return of a ‘great age’, also voices an anxiety that it may be impossible to imagine a future that is unbound by the failures of the past. This essay examines the ways in which Shelley imagines the outcome of the Greek War in Hellas, especially in dialogue with the claims he makes for poetry and poets in A Defence of Poetry (comp. 1821). I argue that what emerges in Hellas is a fraught form of utopian thought that is defined by hazardous struggle, but which may ultimately direct humanity towards a better future.

Published: November 2020

The number of cases of drug-induced liver injury (DILI) has been increasing since the 1990s. DILIs cause up to 40,000 deaths each year. One of the leaders in the number of DILIs are antineoplastic drugs ms, such as alkylating agents, antimetabolites, targeted drugs, monoclonal antibodies, etc. One of the most effective and safe strategies for the treatment and prevention of DILI is to use hepatoprotective drugs. Currently, on the market of the Russian Federation, is available novel drug Heptrong® (does not have an International Non-proprietary Name), which has anti-inflammatory, antioxidant activity and the ability to stabilize and reduce the permeability of hepatocyte membranes, suppress the activity 5-lipoxygenase, a decrease in the synthesis of leukotriene B4, interleukin-1, interleukin-6, which are pro-inflammatory cytokines. The drug activates the antitoxic function of the liver, improves its protein- and lipid-synthesizing functions. Heptrong® neutralizes the processes of inflammation in the liver, thereby reducing the severity of the clinical manifestations of drug-induced lesions.

SOLUTION OF THE PROBLEM OF TRANSIENT AIR DISTRIBUTIONIN VENTILATION NETWORKS OF MINES, TAKING INTO ACCOUNT THERMODYNAMIC AIR FLOW PARAMETERS
Authors: Pavlov Stanislav A.
Published: November 2020

This paper highlights the importance of calculating transient air distribution in mine ventilation networks, taking into account heat ventilation parameters of mine working atmosphere. The change in the temperature of an air flow as it moved along a working with a constant wall temperature was studied. For the network mathematical model of transient air distribution in a ventilation network of the mine, a new resolver was developed which takes into account the revealed regularities of change in air flow temperature from its velocity, temperature and cross-sectional area of mine workings, and allows calculating the change in air temperature as it moves along mine workings. The results of change in air temperature during its movement along the mine working were compared with analytical calculation method and in solving the problem by finite volume method. The obtained simulation results have good convergence. The deviation values obtained in the network model of transient air distribution from the finite volume method do not exceed 7 %.

Reducing the cost of conducting studies of the physical and filtration properties of unmined rocks at a considerable distance from the workings is an urgent task. Its solution will clarify the features of geological structure of the massif and optimize the mining scheme. The article presents the results of the development and operational testing of the tool for transporting measuring instruments along an uncased borehole drilled from underground working. The tool is based on a circuit with two pneumatic cylinders and a pneumatic control valve, the input of which is supplied with compressed air. During tests in the model of the uncased borehole, it was found that the transportation speed is 9 m/min and the generated push force at an air pressure of 10 bar is 58 kgf.

Fecaloma is a mass of hardened faeces difficult to pass through the intestinal lumen. Due to various reasons, a bolus of fecal matter stagnates, accumulates and inspisates in the intestinal lumen, until it becomes big enough to cause intestinal obstruction. Though there are various predisposing factors for the formation of fecaloma but the actual cause of fecaloma formation is still unknown. Small gut fecalomas are very rare. Herein we are presenting a case of 50 year male who underwent laparotomy three times for small gut obstruction caused due to recurrent formation of small gut fecaloma. To our knowledge it is the first case report of recurrent small gut fecaloma obstruction to be reported.

Coronavirus disease 2019 is the outbreak caused by a new strain of coronavirus named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) 1. The outbreak that leads to a global pandemic originated from the city of Wuhan in China 2. According to a CDC report, the commonest underlying conditions among those hospitalized with COVID-19 were diabetes, chronic lung disease, and cardiovascular disease 1. Obesity is a common denominator for cardiovascular disease and diabetes. Previous experience with the H1N1 epidemic showed that obesity is associated with high mortality 3. All of these observations have raised concerns about the impacts that obesity could have on COVID-19.
Translating Workflow Nets to Process Trees: An Algorithmic Approach
Authors: van Zelst Sebastiaan J. , Leemans Sander J. J.
Published: November 2020

Since their introduction, process trees have been frequently used as a process modeling formalism in many process mining algorithms. A process tree is a (mathematical) tree-based model of a process, in which internal vertices represent behavioral control-flow relations and leaves represent process activities. Translation of a process tree into a sound workflow net is trivial. However, the reverse is not the case. Simultaneously, an algorithm that translates a WF-net into a process tree is of great interest, e.g., the explicit knowledge of the control-flow hierarchy in a WF-net allows one to reason on its behavior more easily. Hence, in this paper, we present such an algorithm, i.e., it detects whether a WF-net corresponds to a process tree, and, if so, constructs it. We prove that, if the algorithm finds a process tree, the language of the process tree is equal to the language of the original WF-net. The experiments conducted show that the algorithm’s corresponding implementation has a quadratic time complexity in the size of the WF-net. Furthermore, the experiments show strong evidence of process tree rediscoverability.
A Biologically Motivated, Proto-Object-Based Audiovisual Saliency Model
Authors: Ramenahalli Sudarshan
Published: November 2020

The natural environment and our interaction with it are essentially multisensory, where we may deploy visual, tactile and/or auditory senses to perceive, learn and interact with our environment. Our objective in this study is to develop a scene analysis algorithm using multisensory information, specifically vision and audio. We develop a proto-object-based audiovisual saliency map (AVSM) for the analysis of dynamic natural scenes. A specialized audiovisual camera with 360∘ field of view, capable of locating sound direction, is used to collect spatiotemporally aligned audiovisual data. We demonstrate that the performance of a proto-object-based audiovisual saliency map in detecting and localizing salient objects/events is in agreement with human judgment. In addition, the proto-object-based AVSM that we compute as a linear combination of visual and auditory feature conspicuity maps captures a higher number of valid salient events compared to unisensory saliency maps. Such an algorithm can be useful in surveillance, robotic navigation, video compression and related applications.
