Authors: Öz Okan , D'Alessandro Hilal Dinçer , Batuk Merve Özbal , Sennaroğlu Gonca , Govaerts Paul J.
Published: July 2023

Purpose:

The purpose of this study was to (a) investigate which speech material is most appropriate as stimulus in head shadow effect (HSE) and binaural squelch (SQ) tests, (b) obtain normative values of both tests using the material decided to be optimal, and (c) explore the results in bilateral cochlear implant (CI) users.

Method:

Study participants consisted of 30 normal-hearing (NH) persons and 34 bilateral CI users. This study consisted of three phases. In the first phase, three different speech materials (1) monosyllabic words, (2) spondee words, and (3) sentences were compared in terms of (a) effect size, (b) test–retest reliability, and (c) interindividual variability. In the second phase, the speech material selected in the first phase was used to test a further 24 NHs to obtain normative values for both tests. In the third phase, tests were administered to a further 23 bilateral CI users, together with localization test and the Speech, Spatial, and Qualities of Hearing scale.

Results:

The results of the first phase indicated that spondees and sentences were more robust materials compared with monosyllables. Although the effect size and interindividual variability were comparable for spondees and sentences, sentences had higher test–retest reliability in this sample of CI users. With sentences, the mean (± standard deviation) HSE and SQ in the NH group were 58 ± 14% and 22 ± 11%, respectively. In the CI group, the mean HSE and SQ were 49 ± 13% and 13 ± 14%, respectively. There were no statistically significant correlations between the test results and the interval between the implantations, the length of binaural listening experience, or the asymmetry between the ears.

Conclusions:

Sentences are preferred as stimulus material in the binaural HSE and SQ tests. Normative data are given for HSE and SQ with the LiCoS (linguistically controlled sentences) test. HSE is present for all bilateral CI users, whereas SQ is present in approximately seven out of 10 cases.
Repetitive Negative Thinking in Adolescents Who Stutter
Authors: Tichenor Seth E. , Gerwin Katelyn L. , Walsh Bridget
Published: July 2023

Purpose:

Repetitive negative thinking (RNT) is the process of engaging in negatively valenced and habitual thought patterns. RNT is strongly associated with mental health conditions and often affects quality of life. This study explored RNT in older school-age children and adolescents who stutter to quantify the relationship between RNT and self-reported anxiety characteristics. An additional aim was to describe how individual differences in an adolescent's goal when speaking influences the frequency they engage in RNT.

Method:

Ninety-nine children and adolescents who stutter aged 9–18 years completed a measurement of the frequency/severity of RNT, a screener of anxiety characteristics, and a measure of adverse impact related to stuttering. Children aged 10 years and above also answered questions about their goal when speaking.

Results:

Individual differences in RNT significantly predicted Overall Assessment of the Speaker's Experience of Stuttering (OASES) Total Scores more so than a child or adolescent's age. Higher generalized or social anxiety scores were significantly correlated with more frequent RNT and higher OASES Total Scores. Individual differences in goal when speaking (i.e., whether or not to stutter openly) were found to predict RNT. Finally, 22 children and adolescents (22.2%) also screened positive for generalized anxiety disorder and 32 (32.3%) screened positive for social anxiety disorder.

Discussion:

These data provide strong evidence that (a) many children and adolescents who stutter engage in RNT; (b) children and adolescents who engage more frequently in RNT or who have higher OASES Total Scores may be at increased risk for more characteristics of generalized or social anxiety; and (c) individual differences in goal when speaking can predict the degree to which an adolescent engages in RNT.

Zinc catalyzed, microwave irradiated Sonogashira reaction by Sodium Aluminate (NaAlO2) as a base in water: A Green entente
Authors: Saha Pritam , Mukherjee Koushik
Published: July 2023

The Sonogashira reaction (SNR) is undeniably the most applicable and efficient scheme in chemical synthesis, which involves the formation of C-C bonds by cross-coupling reaction (CCR) with terminal alkyne and halides of aryl or vinyl system. Typically, Pd serves as a catalyst for this reaction, with Cu serving as a co-catalysts and bases can be phosphine or amine. The applicability of such reactions lies in synthesizing medicines, heterocycles, and imitators in products of nature, biologically active complex compounds, nanomaterials, and other organic compounds. In this research, we could implement the SNR effectively without the need for the chemicals mentioned above reagents by using sodium aluminate (NaAlO2) as a base and catalyst as zinc under microwave irradiation (MWR) in water. The approach bears the potential to be in coherence with the principles of green chemistry and make reactions more atom-friendly. In order to achieve inexpensive and eco-friendly energy conditions, we developed one of the straightforward, concise, convergent protocols for sequential coupling and cyclization from Acetylenic species of quinoline-8-ol synthesized in situ by the CCR under MWR. Furthermore, the reaction used zinc as a catalyst and NaAlO2 as a base in the aqueous phase.
Energy consumption comparison at various insulation scenarios: Mid-rise residential buildings, Kabul city
Authors: Rasuli Mohammad Azim , Torii Shuichi
Published: July 2023

An insulating substance is typically used to reduce the amount of heat that enters buildings with air conditioning from the outside. The heat conductivity of this substance is extremely low. In this scenario, having a cost-effective air conditioning system requires using an appropriate insulation material with the right thickness. Up until a certain point, when the material thickness is optimal and will give the maximum overall energy savings, given that the building industry accounts for roughly 40% of worldwide energy consumption and is the greatest producer of greenhouse gas emissions, it is well known that it has a substantial negative influence on the environment too. Therefore, Insulating the outer walls of the building is a recognized method to improve the energy efficiency of buildings in the current setting of ongoing global energy price increases and concern to support global efforts to recover the climate. This study was conducted on a residential building in Kabul city capital of Afghanistan, to study and analyse the insulation materials used to seal the building envelope to calculate how much energy can be saved. Version 4.9 of the HAP program was used to calculate the energy consumption and heating/cooling loads. According to the obtained results, adding insulation to the envelope’s various elements (walls, roofs, windows, etc.) can improve thermal comfort indoors and cut the energy use of the structures under study by between 30 to 40 percent. Especially the amount of heat losses in winter decrease with proper insulation, but due to the low-temperature difference in the summertime, the insulation effect is negligible.

Published: July 2023

The aim of this research was to enable easier access to the food value of coconut for humanity. There was a span of time from the 1950s-1990s where much media coverage discouraged the consumption of coconut, even though it was used in the West since the 16th century. This started due to the supply cut off during WW2, thereby Western researchers had to enable humans to consume corn and soybean oil which had become an established industry by the end of WW2. Therefore, propaganda was used to defame coconut oil. The main argument was that coconut oil has a high percentage of saturated fats, neglecting the fact that a huge sample of humans in Asia have been consuming it for millenniums. Later Western researchers realized that the balance between LDL and HDL is more important and coconut has a good balance. This caused a resurgence in consumption. The biggest problem with coconut is accessing the coconut meat through the hard husk and shell. Therefore, two setups were designed and developed in this work. The first setup enables cutting the coconut fast with utmost safety and environmental benefit and the second setup enables grinding out the coconut meat.

The use of drones for cut-and-fill operations in construction is one area where great progress has been made. Construction sites are now being surveyed by drones in order to gather data for analysis and decision-making. In this paper, we examine the usage of drones for cut and fill operations in construction and how they might be used in conjunction with aerial analytics technologies to produce better outcomes. We present a case study in which a construction site was surveyed by drones in order to gather topographic and elevational data. To create detailed maps and 3D models of the location, this data was analyzed using a suite of aerial analytics technologies. The article's findings demonstrate that traditional surveying techniques can be greatly sped up and cost-effectively replaced by drones in cut and fill construction operations. Additionally, using aerial analytics technologies enables a more precise and in-depth analysis of the collected data. As a result, we draw the conclusion that the application of drone technology and aerial analytics has the potential to transform the construction sector and boost project productivity.

Authors: Shinde Vaishnavi , Sonavane Omkar , Dadhich Shishir
Published: July 2023

With the aim to reduce the adverse environmental impact caused due to the urban transportation system, an alternative solution is identified. Non-motorized transport is the most relevant alternative for low-carbon mobility. It not only helps in the city's sustainable development but also helps reduce traffic problems and improve one’s health. In India and in foreign countries, the government is taking initiatives to promote Non Motorised Transport (NMT) and funding the project to come into operation. In most of the surveys, the solutions are given for improving NMT infrastructure, but from the literature, a gap is found that only improving the infrastructure is not important, instead at first it is important to recognize the actual need as to where we need to develop infrastructure, secondly recognizing the potential trips and then proposing infrastructure respectively. There is no study done on the potential trips that could be converted to NMT with reference to Nashik City. This research aims to study the mobility plan of the Gangapur road area of Nashik city and identify the potential trips of such area which can be shifted to non-motorised transport. The survey includes the study of daily trips taken by people for various activities, which caters to all age groups. The study also includes an understanding of the trip length, alignment of the roads, and important commercial and institutional zones in the area. A thought is also given for redesigning Public Bicycle Sharing System in the study area for the maximum usage of the system. A module is proposed after an analysis of the survey and the existing transportation plan. A plan representing the module and indicating the potential trips that can be converted to non-motorised transport is proposed.

Published: July 2023

Concrete is the most commonly used building material. Even then, it has a drawback that it hasheavy density. Hence, researches are progressing everywhere to develop a new building material, which has low density, less water absorption as well as economical. And here lies the importance of foamed concrete. Foamed concrete is a type of lightweight concrete in which stable foam is used as the main ingredient. Stable foam is produced from standard foaming agent using a foam generator. The peculiarity of foamed concrete is that no coarse aggregate is used in it. An attempt is made in this research to use palm oil fuel ash as a partial replacement for cement and red gypsum as a partial replacement for manufactured sand. Both of these materials are waste materials and are abundantly available. The concrete made up of this will be more sustainable as well as economical. By adjusting the addition of stable foam, foamed concrete of various densities can be developed. Foamed concrete blocks made up of these materials can be used for load bearing as well as non-load bearing masonry works. It has been observed that the addition of Palm Oil Fuel Ash and Red Earth has improved the properties of foamed concrete.

Authors: Ravikar Aboli , Joshi Deepa A. , Menon Radhika
Published: July 2023

Despite the fact that the concrete is prone to fracture formation, it is a material that is widely utilized in the construction industry as it is affordable and easily available. Therefore, during the past two decades, there has been a surge in interest in self-healing materials, especially those that have the ability to repair themselves in environmentally friendly and sustainable concrete materials. However, because each research institute uses its own testing methods to determine how effective a treatment is, choosing the most efficient method is difficult. Self-healing concrete, also known as SHC, has the ability to heal and reduces the need to locate and repair internal damage, such as cracks, without the need for intervention from outside the structure. This helps in reducing the costs, increase durability and reduces reinforcement corrosion and concrete deterioration. This study provides a comprehensive overview of SHCs, taking into account the strategies, and effectiveness of self-healing. Based on the application, multiple self-healing concrete strategies are identified through Literature. Using Multi-Criteria Decision Making Tool (MCDM), Fuzzy Analytic Hierarchy Process (FAHP), it is found that out of five factors selected, Ease of Availability Factor got maximum preference and Performance Time Factor got least preference. Among four strategies identified, Chemical based Self-Healing has maximum weight followed by Bacteria based Self-Healing. Natural Self-Healing is least preferred. Besides, limits and future possibilities of SHC, as well as the area of interest research points for future examinations, are additionally effectively featured.

Rain Water Harvesting Technique Implementation for the Chhadvel Korde Village, Maharashtra
Authors: Nadupuru Shobha Rani , Shewale Manisha
Published: July 2023

Water is one of the most important resources on Earth. In every way, water is crucial to our daily existence. The amount of water that is available in cities is never enough to meet the entire demand. We must rely on water from underground sources because surface water is not readily available. The amount of rainwater that soaks into the subsurface and replenishes ground water has significantly decreased as a result of rapid urbanisation. In this instance, there must be additional supply to satisfy the demand. When it rains, pure rainwater can be gathered "wherever it falls" to instantly replace the water supply. The act of gathering and organising rainwater in a systematic way for later use is referred to as "rainwater harvesting". Two types of rainwater harvesting that could be used in the research region are rooftop and surface runoff harvesting. By adopting a rainwater harvesting system and constructing natural percolation pits, the groundwater level, soil moisture, and soil fertility can all be increased for plantations. Therefore, using this simple strategy typically leads to more vegetation, which raises the aesthetic value. This article examines every rainwater harvesting system established in the Maharashtra district of Sakri in Chhadvel Korde.

Published: July 2023

Reclaimed Asphalt Pavement (RAP) has gained significant attention in recent years as a sustainable alternative to natural aggregate in road construction. This study presents a comparison of the physical attributes of RAP and natural aggregate, with a focus on their potential use as base and subbase materials in flexible pavements. The physical attributes of RAP and natural aggregate were evaluated using standard laboratory tests, including particle size distribution, specific gravity, water absorption, impact value test, Los Angles Abrasion test, flakiness and elongation test. The research concluded that RAP is comparable to natural aggregate in terms of particle size distribution and bulk density but has lower water absorption, impact, and abrasion values. The results shows that RAP is almost 53% more tougher that natural aggregate when tested for Aggregated Impact test and 30% more harder than natural aggregate when compared by Los Angeles abrasion test. Also, heatmap was used to analyse the relationship between physical attributes of natural aggregate and reclaimed asphalt pavement which depicted 93% similarity The findings suggest that RAP has the potential to replace natural aggregate in flexible pavements, further study is required to determine its long-term performance and durability.

Authors: Gahir Gurmeet Singh , Matharu Surendrapal Singh
Published: July 2023

Lubricant derived from Mineral oil are not renewable, detrimental to health, and fluctuating in price. As a result, vegetable based oils are regarded as best substitute of mineral oil in the manufacturing of lubricants. It has become vital to do analysis on the application of unconsumable oils for stable industry lubricant development. In this work, the characteristic investigation of lubricant derived from vegetable which are not edible (ex-Jatropha) that can be used for industrial application is analysed. The oil was analysed and changed to make it suitable for development as lubricants for industrial uses. As a control, a mineral based oil that is commercially available as lubricant (SAE 20/W50) was employed. Jatropha oil was modified to improve viscosity while modification has also reduced the viscosity index in parallel. Jatropha oil, contrasting any other vegetable oils, has outstanding cold-flow capabilities, and mitigation of the oils has further improved oil’s cold-flow properties. The pH exhibited by modified Jatropha oil is in the alkaline scale, a high viscosity index. Thus, both modified and unmodified (Esterified) Jatropha oil have been proven to be appropriate for industry usage in low-temperature networks. The modified Jatropha oil was discovered to be an environmentally safe substitute of the oil that are mineral based lubricant (SAE 20/W50) to be used in 2- stroke engines, metal shaping, and gear lubrication in the food treating industry.

Published: July 2023

A hydrocyclone is a centrifugal classifier that separates particles by size using centrifugal force. Applications for hydrocyclones are incredibly varied. It is used to separate solids from liquids, liquids from liquids, and gases from liquids. It is easy to install and use, simple, inexpensive, and low maintenance. It serves as the brain of the mineral processing plant and is used to process water in important sectors of the textile, petroleum, chemical, paper, and agricultural industries. It is made up of a cylindrical and a conical portion. Three holes are present—two outputs and one for the feed intake. The under flow was for pollutant outlet and the vortex finder was for water outlet. Pressure drop, geometrical factors, and feed size distribution all have an impact on the hydrocyclone's efficiency. The present work reviews the shape optimization of vortex finder, spigots, air core and walls of the hydrocyclone for enhancing the desired outcome of the hydrocyclone.
Effects of Purge-Flow Rate on Microbubble Capture in Radial Arterial-Line Filters
Authors: Herbst Daniel P.
Published: July 2023

The process of microbubble filtration from blood is complex and highly dependent on the forces of flow and buoyancy. To protect the patient from air emboli, arterial-line filters commonly use a micropore screen, a large volume housing with purpose-built shape, and a purge port to trap, separate, and remove circulating microbubbles. Although it has been proposed that an insufficient buoyancy force renders the purge port ineffective at removing microbubbles smaller than 500 μm, this research attempts to investigate the purge flow of an arterial-line filter to better understand the microbubble removal function in a typical radial filter design. As its primary objective, the study aims to determine the effect of purge-flow rate on bubble capture using air bolus injections from a syringe pump with 22-gauge needle and Doppler ultrasound bubble detection. The measureable bubble size generated in the test circuit ranged between 30 and 500 μm, while purge flow was varied between .1 and .5 L/min for testing. Statistical analysis of the test data was handled using a repeated measures design with significance set atp< .05 level. Outcomes demonstrated that higher purge flows yielded higher bubble counts, but the effect of purge-flow rate on bubble capture decreased as bubble size increased. Results also showed that purge flow from the test filter was capable of capturing all bubble sizes being generated over the entire flow range tested, and confirms utility of the purge port in removing microbubbles smaller than 500 μm. By analyzing bubble counts in the purge flow of a typical radial-filter design, this study demonstrates that currently available micropore filter technology is capable of removing the size range of bubbles that commonly pass through modern pump-oxygenator systems and should continue to be considered during extracorporeal circulation as a measure to improve patient safety.
Endothelial Glycocalyx and Cardiopulmonary Bypass
Authors: Myers Gerard J. , Wegner Julie
Published: July 2023

On the outer surface of a human cell there is a dense layer of complex carbohydrates called glycocalyx, also referred to as glycans or the sugar coating on the cell surface, which is composed of a complex array of oligosaccharide and polysaccharide glucose chains that are covalently bonded to proteoglycans and lipids bound to the cell membrane surface. Studies of an intact endothelial glycocalyx layer (EGL) have revealed a number of critical functions that relate the importance of this protective layer to vascular integrity and permeability. These functions include the following: stabilization and maintenance of the vascular endothelium, an active reservoir of essential plasma proteins (i.e., albumin, antithrombin, heparan sulfate, and antioxidants), a buffer zone between the blood (formed elements) and the surface of the endothelium, and a mechanotransducer to detect changes in shear stress that facilitate vascular tone. There have been numerous review articles about the structure and function of endothelial glycocalyx over the past two decades, yet there still remains a significant knowledge gap in the perfusion literature around the importance of EGL. Perioperative fluid management and gaseous microemboli can both contribute to the damage/degradation of endothelial glycocalyx. A damaged EGL can result in systemic and myocardial edema, platelet and leukocyte adhesion, fluid extravasation, and contributes to microvascular perfusion heterogeneity. Knowledge of the importance of endothelial glycocalyx will enable clinicians to have a better understanding of the impact of gaseous microbubbles, hyperoxia, and ischemic reperfusion injury during cardiac surgery. The purpose of this article is to provide an in depth review of the EGL and how this protective barrier impacts the microcirculation, fluid homeostasis, inflammation, and edema during cardiac surgery.
Low Oxygen Delivery as a Predictor of Acute Kidney Injury during Cardiopulmonary Bypass
Authors: Newland Richard F. , Baker Robert A.
Published: July 2023

Low indexed oxygen delivery (DO2i) during cardiopulmonary bypass (CPB) has been associated with an increase in the likelihood of acute kidney injury (AKI), with critical thresholds for oxygen delivery reported to be 260–270 mL/min/m2. This study aims to explore whether a relationship exists for oxygen delivery during CPB, in which the integral of amount and time below a critical threshold, is associated with the incidence of postoperative AKI. The area under the curve (AUC) with DO2i during CPB above or below 270 mL/min/m2was calculated as a metric of oxygen delivery in 210 patients undergoing CPB. To determine the influence of low oxygen delivery on AKI, a multivariate logistic regression model was developed including AUC < 0, Euroscore II to provide preoperative risk factor adjustment, and incidence of red blood cell transfusion to adjust for the influence of transfusion. Having an AUC < 0 for an oxygen delivery threshold of 270 mL/min/m2during CPB was an independent predictor of AKI, after adjustment for Euroscore II and transfusion [OR 2.74, CI {1.01–7.41},p= .047]. These results support that a relationship exists for oxygen delivery during CPB, in which the integral of amount and time below a critical threshold is associated with the incidence of postoperative AKI.

Indications for extra corporeal membrane oxygenation (ECMO) have expanded in recent years, and it has become an invaluable tool in the care of adult patients in severe cardiogenic shock or respiratory failure. Understanding the physiologic effect of ECMO has also further developed, allowing for improvements in the management of the potential morbidities associated with this technology. Here, we present a case of acute bowel ischemia that developed while the patient was on central venoarterial ECMO.

Acquired von Willebrand syndrome (VWS) due to loss of high-molecular-weight multimers (HMWMs) has been reported with longer term mechanical devices and is associated with mucosal bleeding, a primary hemostasis type of bleeding. However, little is known whether a similar defect occurs in patients with short-term mechanical circulatory support (STMCS) devices. We reviewed von Willebrand factor (VWF) profiles in patients with STMCS devices who underwent VWS workup from December 2015 to March 2017 at an academic quaternary care hospital. There were a total of 18 patients (57.0 ± 12.7 years old; 83.3% male) including nine with mucosal bleeding and nine with decreasing hemoglobin. The STMCS devices included Impella (n = 11), Impella and right ventricular assist device (n = 2), and an extracorporeal membrane oxygenator (n = 5). The mean HMWM by quantitative VWF multimer analysis was 3.6% ± 1.3% (normal cutoff: 18–34%). In all 10 cases in which VWF activity, fibrinogen, factor VIII, or VWF antigen level were obtained, they were either normal or elevated. All cases demonstrated high normal or elevated levels of low molecular weight multimers (LMWMs). These findings are consistent with type 2 VWS (qualitative defect). This is the first study that quantitatively describes STMCS device–associated HMWM loss, which may contribute to mucosal bleeding. This finding may have implications for intraoperative management during implantation of longer term devices or heart transplantation or other surgery while on STMCS.

Many blood conservation techniques and strategies have been implemented to aid in decreasing the use of allogenic blood utilization during pediatric cardiothoracic surgery. Use of techniques, such as acute normovolemic hemodilution, retrograde autologous prime, venous autologous prime, and autotransfuion, may lead to a decrease in the need for allogenic blood products. Autotransfusion has become a standard of care for all cardiothoracic surgical procedures requiring cardiopulmonary bypass (CPB). Although widely used, there is still debate over which wash solution will produce the most physiologically normal autotransfusion product. Pediatric patients can be at a higher risk for electrolyte imbalance intraoperatively and postoperatively. In an attempt to minimize this, we sought out to evaluate three different wash solutions and how they would affect the final autotransfusion product. This comparison consisted of three wash solutions; .9% sodium chloride, Normosol-R™, and Plasma-Lyte A. Based on the evaluation of all wash solutions, Plasma-Lyte A produced the most physiological normal final autotransfusion product in regards to electrolytes.
