Authors: SOLMAZ Mehtap , E sa
Published: August 2023

Background and Aims:
Infectious diseases are affecting people more often than before and that is the main cause of morbidity and mortality in developed and developing countries. Taking the necessary measures by diagnosing earlier and using appropriate antibiotics made significant contributions to the control of the infections. In our study we aimed to develop a method for the diagnosis of some of pathogen gram-negative bacteria by using multiplex PCR (Polymerase Chain Reaction) from a positive blood culture bottles.

Methods:
Extraction method was applied from the blood cultures in which growth was detected. After mono¬plex PCR experiments were performed and images were obtained, multiplex PCR experiments were performed. Considering the product sizes and primers for multiplex PCR, a quadruple bacterial set was prepared by matching Acinetobacter baumannii, Escherichia coli, Serratia marcescens and Pseudomonas aeruginosa. Experiment conditions and tube concentration were adjusted by making serial trial experiments.

Results:
Multiplex-PCR-based methods have the advantage of defining multiple pathogens in a single PCR reaction. These are used for identifying respiratory infections, bacteraemia, and meningitis which are common bacterial and viral diseases. Type-specific genes and molecular techniques including identification of infectious diseases with nucleic acid amplification are promising tools for the verification of accurate diagnosis. The feasibility of this assay in routine diagnostic testing was evaluated using 146 positive blood cultures and 40 negative blood culture samples.

Conclusions:
Early diagnosis and intervention with effective antimicrobial therapy is important in reducing mortality that is associated with bloodstream infections.
Intraocular pressure changes during Valsalva maneuver
Authors: V Satyanarayana , Bhansali Swaroop , Kosti Ravi , Balananda Perugu , L Narasimha
Published: August 2023

Background: Valsalva maneuver (VM) is the performance of forced expiration against a closed glottis. Activities such as straining during defecation, blowing a balloon, lifting heavy weights, or playing the wind instruments like saxophone entail the performance of the VM. Even though many parameters such as blood pressure and pulse rate are changed to certain extent during VM.

Aims and Objectives: This study aims to know whether any intraocular pressure (IOP) changes take place by performing VM. IOP is the fluid pressure of the eye. Increased IOP leads to ischemia of retinal nerve fiber. Decreased IOP can lead to impairment of the ocular functions. Elevation of IOP is the major risk factor to develop glaucoma primary open-angle glaucoma (POAG).

Materials and Methods: 52 intern students (28 males and 24 females) among 20 myopics and 32 emmetropes are selected for this study from GITAM Institute of Medical Sciences and Research. Complete systemic and ocular examination is conducted. IOP is recorded with the correction of central corneal thickness. All of them are trained for “Valsalva Maneuver” for 10 days during their stay in unit posting. VM is practiced for 2 min. The IOPs recorded before and after the VM procedure.

Results: There is a rise in the IOP after VM in all the 52 internee students. The average raise in the IOP after VM for 2 min is about 2.81 mmHg. IOP raised more in females than males. There is an increase of IOP in emmetropes than myopes.

Conclusion: VM raises the IOP in all the individuals. The POAG individuals should be cautioned during the weight lifting, conditions which may lead to increase the intra-abdominal pressure. These conditions cause the natural VM. All these maneuvers can cause fluctuations in the IOP, which are dangerous and may lead to the progression of POAG. VM can be used as screening procedure for glaucoma.

Aims: This study evaluated the subjective experience of masticatory performance and masticatory efficiency in partially edentulous patients rehabilitated with three different types of removable partial dentures (RPDs). Materials and methods: This was a crossover randomized study, which was carried out at the prosthodontics clinic of the University of Ghana Dental School clinic. Sixteen patients requiring RPDs but had never worn one before were consecutively recruited for the study. Three different RPDs [i.e., cobalt chromium, acrylic, and thermoplastic resin (iFlex)] were fabricated for each patient. Masticatory efficiency was assessed using a singlesieve method after chewing raw carrots. The subjective experience of masticatory performance was also assessed using a questionnaire after 1 week of using each denture. Results: The cobalt-chromium denture recorded the highest masticatory efficiency (31.4%), and the iFlex denture recorded the lowest (27.9%). Subjectively, the cobalt-chromium denture was ranked as the denture they were most satisfied with when chewing with the least being the acrylic denture. Conclusion: Despite the fact that the iFlex, flexible denture had an overall appeal, where effective chewing is of great concern to prospective RPD patients, the cobalt-chromium denture may have a slightly better advantage.

Characterization Of Acoustofluidic Geometric Traps By Means Of Defocus Particle Tracking
Authors: Rossi M. , Joergensen J.H. , Bruus H.
Published: July 2023

In this work we used the General Defocusing Particle Tracking method to measure the three-dimensional trajectories of 10-μm-diameter polystyrene beads moving inside a micro-acoustofluidic device. The aim is to measure the change in acoustic energy density induced by localized modifications of the channel geometry. The measurements were performed in a glass capillary tube with a rectangular cross-section of 2.0 mm × 0.2 mm. The wall thickness of the capillary tube is 140 μm and it was locally increased by gluing a glass slide with a thickness of 100 μm. The acoustic energies at five different frequencies around the expected resonant frequency have been estimated for the single-glass and double-glass region from the measured particle paths. The results showed a down-shift of the resonant frequency in the double-glass zone, as expected from theoretical predictions. This approach can be used to create multiple acoustofluidic traps based on simple geometrical modifications of the microchannel.
Modal Analysis Of Concentration Information In A Magnetic Micromixer
Authors: Ergin F.G. , Kitenbergs G. , Cēbers A.
Published: July 2023

Mixing is one of the most frequently used processes in microfluidic devices and Lab-on-a-Chip applications, therefore subtantial flow field investigation efforts are spent to achieve high performance micromixers. In this work, we revisit a magnetic micromixer experiment, where velocity, concentration and interface investigations had been carried out. The magnetic micromixer exploits a phenomenon called magnetic microconvection, which appears on an interface of miscible magnetic and nonmagnetic fluids. Initial qualitative concentration measurements are improved, both in terms of accuracy and resolution. The improvements in the experimental setup, improved microfluidic channel geometry, more accurate syringe pumps and inclusion of a concentration calibration step resulted in an accurate, time resolved and quantitative description of the concentration information for magnetic microconvection. In the current work we perform a modal analysis of the concentration field using Proper Orthogonal Decomposition (POD). The modal information provides crucial details about the mixing process at the interface for the magnetic microconvection phenomenon, giving a way to characterize and improve such mixers.
Event-based imaging velocimetry applied to a cylinder wake flow in air
Authors: Willert C. , Klinner J.
Published: July 2023

Event-based vision is a new upcoming field within the field of computer vision. Unlike conventional frame-based imaging, event-based vision (or dynamic vision sensing) asynchronously records binary signals of contrast changes at the pixel level with microsecond resolution. Event-based imaging of small particles illuminated by a laser or other continuous light source generates streaks of events in a space-time domain. From this data the particles’ position in both space and time can be inferred. The present work explores the possibilities of harnessing the potentials of event- based vision for fluid flow measurement with focus on two-dimensional, two-component velocity field estimation at particle image densities corresponding to that of conventional PIV. Three different motion detection schemes are implemented. Measurements of a cylinder wake flow demonstrate that EBIV provides time resolved velocity data that is suitable for the retrieval of flow statistics as well as spectral and modal analysis. The present work is an extension of the recently published Exp. Fluids article by the authors on event-based imaging velocimetry and provides further details on current limitations related to event-based imaging.
Resolution Considerations For Structured Illumination Microscale Particle Tracking Velocimetry
Authors: Spadaro M. , Yoda M.
Published: July 2023

In microscale particle velocimetry, the spatial resolution of velocity measurements along the optical axis is often degraded by signal from tracer particles outside the focal plane. Structured illumination microscopy particle tracking velocimetry (SIM PTV) can eliminate most of this out-of-focus signal by using illumination with a non-zero spatial frequency to preferentially illuminate the in-focus particles. Two such (raw) images can then be combined to eliminate the background signal and demodulate the image. T he objective of this study was to quantify and optimize the spatial and temporal resolution of SIM PTV based upon Poiseuille flow in a microchannel at Reynolds numbers Re 0.02. The axial spatial resolution, estimated for this known velocity profile from the standard deviation of the velocity measurements, is improved (i.e., reduced) by at least a factor of 2 compared with the results for a uniformly illuminated flow. This axial spatial resolution, which is given by the point spread function of the imaging system, is in good agreement with theory. The spatial frequency of the illumination that optimizes the spatial resolution is a function of the scattering area of the tracer particles. In terestingly, increasing the number of raw images does not appear to improve the axial resolution. Finally, the temporal resolution of SIM PTV is estimated based upon both image and velocity acquisition times.
Feasibility Analysis On Transient Speed Of Sound Investigations Using Laser-Induced Thermal Acoustics In Evaporating Droplets
Authors: Steinhausen C. , Gerber V. , Preusche A. , Dreizler A. , Weigand B. , Lamanna G.
Published: July 2023

The development of combustion processes to achieve higher efficiencies has led to a continuous increase in operating pressures that exceed the critical point of the injected fluids. Especially for supercritical atmospheric conditions with respect to the injected fluid, the fundamental physics of the occurring mixing and evaporation processes are not fully understood. In particular, quantitative data for the validation of numerical simulations as well as analytical models remain sparse. Laser-induced thermal acoustic (LITA) is a seedless, non-intrusive measurement technique capable of detecting speed of sound data within these mixing processes. Until now, the feasibility of time-resolved LITA measurements in complex fluid dynamic processes has not been proven. Therefore, a feasibility analysis on transient speed of sound investigations using laser-induced thermal acoustics in evaporating droplets has been conducted. LITA has hereby been applied in the wake of a free-falling acetone droplet evaporating in a nitrogen atmosphere at nearcritical conditions. To the authors’ best knowledge, this is the first-time transient LITA measurements investigating macroscopic fluid phenomena, such as fluid injection and evaporation processes, have been conducted. The evaporation of the droplet has been simultaneously visualised using shadowgraphy, whereas time-resolved speed of sound data have been directly detected by a high-speed LITA system with a high-repetition rate excitation laser source.
Study Of Flame-Wall Interaction : Influence Of Effusion Cooling On Pollutant Emissions
Authors: Milu-Vaidesegan S. , Orain M. , Doublet P. , Bellenoue M.
Published: July 2023

For several years, engine manufacturers have had to meet increasingly stringent standards on pollutant emissions. Studying the flame/wall interaction is essential to control pollutant emissions and extend the lifetime of gas turbine. An inherent constraint of combustion chambers is that the walls are cooled by air introduced through multi-perforation (effusion cooling). The problem is that this injection of cold air into the combustion chamber disrupts the oxidation reactions of the fuel either by freezing them, which yields the emission of large quantities of CO, UHC and soot or by bringing fresh air to the rich areas, which is very favourable to the formation of thermal NOx. The focus of this work is to investigate the influence of parameters such as burner flow rate, cooling flow rate and equivalence ratio on the reaction zone. Experiments were conducted with a multi-perforated plate placed above a flat flame burner to simulate the head-on interaction between an aeronautical injector and an effusion cooled liner.

Making a prototype of the Fuel Pump Test Bench with a method of measuring fuel pressure, current and temperature of a microcontroller-based fuel pump
Authors: Rosadi Ajib , Satmoko Ambar Wanto , Afani Randy Putra
Published: July 2023

The object of this research is a vehicle with a fuel injection system and uses a fuel pump to produce pressurized fuel.  The fuel pump has decreased performance for some time of use. Decreased performance is characterized by abnormal engine power. But these symptoms can also be caused by other factors such as disturbances in the ignition system, fuel system or air intake system. To obtain the true causative factors by the workshop, a comprehensive examination of related systems is carried out. F the causative actor in the fuel system  is the fuel pump, then the action taken by the workshop is replacement. In two-wheeled vehicles, fuel pump replacement  is carried out after the fuel pump cannot operate. While four-wheeled vehicles, fuel pump replacement  is recommended every 80,000 km. From the average data of Astra workshops that the number of vehicles that replace fuel pumps is 3 to 4 units within one month. Based on the procedure for checking the condition of  the  Astra vehicle fuel pump, which only measures fuel pressure and the resistance value of the fuel pump coil. The standard fuel pressure value is 2.94 bar and the fuel pump coil resistance value  is 0.8 ohms. The measurement of the 2 parameters does not represent the actual condition of  the fuel pump, whether  the fuel pump can still be used or must be replaced. According to Denton in a book entitled Automobile Electrical and Electronic System Fourth Edition (2012) that  the right fuel pump testing method  must be with manufacturing standards, namely a flow discharge of 120 liters per hour with pressure conditions of 3 bar, source voltage of 12 volts, coil resistance of 0.8 ohms and maximum current to the coil of 10.5 amperes. As a solution to determine whether the fuel pump can still be used or must be replaced, it is necessary to make  a fuel pump test bench with a method of measuring fuel pressure, current and fuel pump temperature. In order for all measurable parameters to be displayed into a conclusion, this tool is made based on microcontrollers. This fuel  pump test bench can be used to determine the condition and predict the age of the fuel pump.

"The cytogenetic aberrations induced by doxorubicin (DOX) may be influenced by diet. Investigation regarding effects of low doses of DOX on chromosomal aberrations frequency in mice bone marrow. The study explored a possible relationship between diet, follow-up period, and cytostatic doses. Four mice groups received normal or high-fat (pork) diet. At the beginning of the 8th day mice from each group received a single intraperitoneal injection with DOX (dose range: 1.7-7.7 mg/kg b.w.) or isotonic saline solution (0.02 mL/g control mice). In the 10th (groups I, II) and 14th (groups III, IV) days from the beginning of the experiment, the mice were euthanized and chromosome aberrations were tested in bone marrow cells. The body weight of all mice who received DOX decreases, especially at higher doses. In the first three days post-injection, weight loss percentage was significantly influenced by DOX doses and/or type of diet (p<0.003). The interaction between the type of diet and DOX doses was not statistically significant in the follow-up period (p interactions >0.05). DOX doses were able to increase the frequency of chromosomal aberrations. DOX acts as a potent inductor of cytogenetic aberrations in bone marrow cells, regardless of the type of diet."
