Published: October 2023

We present a comprehensive study on the utilization of Ni-doped Co3O4 nanoparticles for energy storage applications, particularly in supercapacitors. X-ray diffraction analysis confirms the structural integrity and phase purity of the samples, exhibiting the characteristic peaks of the cubic spinel structure X-ray photoelectron spectroscopy confirms the presence of Co, Ni, and O elements, with different valence states observed. Scanning electron microscope images reveal irregular nano-flakes with increased particle size and reduced porosity as Ni doping concentration rises. Electrochemical analysis, including cyclic voltammetry and galvanostatic charge-discharge tests, demonstrates promising performance. Specifically, the 3 wt% Ni-doped Co3O4 sample exhibits a maximum specific capacitance of 299 F/g at a scan rate of 5 mV/s. The GCD profile of all the three Ni doped Co3O4 Nps were carried out. All of them revealed quasi triangular charge-discharge curve that are due to both pseudo capacitive and electric double layer process. Moreover, the 3% Ni-doped Co3O4 nanoparticles demonstrate a maximum specific capacitance of 347 F/g at a scan rate of 1.5 A/g. Additionally, the 5% Ni-doped Co3O4 nanoparticles exhibit an impressive capacity retention of 92.87% even after 1500 cycles. Our findings indicate that appropriate Ni doping on Co3O4 nanoparticles enhances their electrochemical performance, great potential for supercapacitor applications.

Authors: Li Pei zheng , Xie Cong , Guo Xin
Published: October 2023

Anaerobic threshold (AT) is the critical point at which the energy system produces different energy supply patterns during exercise. At present, the measurement of AT is obtained through cardiopulmonary exercise testing (CPET). The heart rate at which an individual enters the anaerobic threshold during cardiopulmonary exercise testing is referred to as the anaerobic threshold heart rate. When using sports prescription or exercise plan as a means to improve health status or quality of life, it is necessary to determine the specific exercise intensity according to the individual's anaerobic threshold heart rate. This paper aims to using whale optimization algorithm based random forest algorithm (WOA-RF) to predict the anaerobic threshold heart rate of individuals by collecting the basic physical characteristics, heart rate and load in CPET. Data that are easy to collect for daily measurement are selected: age, gender, height, weight, initial heart rate, initial load, relative heart rate increment at 30% maximum load, relative heart rate increment at 50% maximum load, relative heart rate increment at 70% maximum load, maximum heart rate, and maximum load.In the result of predicted value: RMSE=7.9445, MAE=6.4206, R2=0.7152. We consider the feasibility of prediction anaerobic threshold heart rate by WOA-RF machine learning algorithm to be acceptable.

Published: October 2023

In the literature amathematical model had been presented to transport a homogeneous product from multi-source to multi-destination, to meet the demand of each destination at a time. Both the demand and the supply were assumed to vary within a certain range. The total cost bounds of transportation were obtained by using the LINGO solver. Here we emphasize that carbon emission, and inventory cost of a product during transportation and in destinations is an important factors in deciding these cost bounds. Besides, consideration of some realistic constraints such as transport vehicle capacity and transport load limitation on a given route is also an important factor. Based on this notion, we extend the original model to include these carbon emission and inventory costs along with some realistic constraints and use the same solver to find out the total cost bounds. Numerical studies demonstrate that such an integration of carbon emission, inventory and transportation costs changes the total cost bounds reasonably. The conclusion is drawn by discussing the limitations of the current model and highlighting the scope for further research.

Theoretical, Numerical and Experimental Investigation of the Inlet and Exit Diameter Effect of Convergent-Conical Nozzles on Thrust Force and Volumetric Flow Rate
Authors: HIZARCI Berkan , KIRAL Zeki
Published: October 2023

It is possible to see convergent conical type nozzles everywhere, from daily life to rocket science. They are utilized as the main part of the propulsion system in many applications such as air blow guns for spraying, steam turbines for compression, rockets for thrust generation, satellites for altitude control and so on. Although the convergent conical nozzle is a well-known nozzle, there are few studies on the effects of geometric changes by comparing more than one approach together. Therefore, this study investigates thrust and volumetric flow rate for different inlet and exit diameters of the convergent conical nozzles theoretically, numerically and experimentally. In this study, the quasi-one-dimensional Euler equations are defined for the theoretical investigation of convergent conical nozzles. However, in this approach, many important features such as viscous losses are neglected. In fact, nozzle flows have highly complex features including shock waves, turbulence, and boundary layers due to compressible effects. Thus, Computational Fluid Dynamic (CFD) simulations are performed with ANSYS Fluent for numerical investigation of the nozzle in this study. CFD simulations provide a better understanding and illustration of convergent conical type nozzle flows. For a third approach, the experimental investigation is conducted for thrust and volumetric flow rate measurements. Theoretical and numerical results are compared with the experimental results and similarity ratios are defined to find the closest to the experimental results.

Published: October 2023

In modern medicine, image recognition via segmentation of anatomical regions and automatic classification of diseases using medical images has a growing potential role in diagnosis of various diseases. Scintigraphy of thyroid is one of the established imaging modalities for diagnosis of thyroid gland disorders. In our study, the speckle noise was reduced in the scintigraphy images with the optimized Bayesian nonlocal mean filter. The thyroid gland was automatically segmented by local based active contour method and the thyroid gland pathologies were classified with convolutional neural networks (CNN). The proposed computer aided diagnosis (CAD) system was compared with Pyramid of Histograms of Orientation Gradients (PHOG), Gray Level Co occurrence Matrix (GLCM), Local Configuration Pattern (LCP) and Bag of Feature (BoF) methods. The common pathological patterns of scintigraphic images of the thyroid gland were successfully classified by CNN with an overall success rate of 91.19%. The comparative methods were PHOG, GLCM, LCP and BoF methods which provided overall success rates of 7.61%, 86.04%, 88.91% and 85.72% respectively. The proposed CNN based automatic diagnosis system provided promising results compared to handcrafted methods.
Sıyırıcı Olarak Kullanılan Polimer Boncuklarının ve Farklı Havalandırma Yoğunluklarının Membran Tıkanması Üzerine Sinerjistik Etkisi
Authors: YAVUZTÜRK GÜL Bahar , KOYUNCU İsmail
Published: October 2023

Membran biyoreaktörlerin (MBR) işletimi sırasında karşılaşılan en önemli problemlerden biri biyotıkanma sorunudur. Bu makalede düşük ve yüksek havalandırma yoğunluğunun (150 L/s ve 350 L/s) ve boncuk kullanımının membran biyotıkanması üzerindeki sinerjistik etkisinin belirlenmesi amaçlanmıştır. Bu sorunun çözümüne yönelik olarak, öncelikle biyofilm sıyırıcı etkisinden faydalanmak amacıyla polimer boncukların üretimi ve optimizasyonu yapılmıştır. Seçilen boncuklar ile yüksek ve düşük iki farklı havalandırma yoğunluğunda üç reaktör işletmesi gerçekleştirilmiştir.

Optimizasyon sonuçlarına göre %12,5 polivinil alkol (PVA) ve %1 sodyum aljinat (S.A) kullanılarak hazırlanan, 2 saat süre ile %5,5 borik asit-%2 CaCl2 karışımında ve 15 dakika süre ile 0,3 M fosfat çözeltisi içerisinde bekletilen boncuklar seçilmiştir. 350 L/s ile yapılan 1. MBR işletmesi sonucunda transmembran basıncı (TMP) 280 mbar olarak kaydedilirken havalandırmanın yoğunluğunun yarıya düşürüldüğü ikinci işletme sonunda TMP 440 mbar’a yükselmiştir. Bu sonuçlara göre membran biyotıkanması, düşük havalandırma yoğunluğunda yüksek havalandırma yoğunluğuna göre %57 oranında artış göstermiştir. Kimyasal yıkama sonrası yüksek havalandırma koşulları ile 3. kez işletilen MBR’da işletme sonunda maksimum TMP değeri 350 mbar olarak kaydedilmiştir. Yüksek havalandırma koşullarındaki iki işletme karşılaştırıldığında 1. işletmeye göre 3. işletme sonunda TMP değerinde gözlenen %25 artış membran modülünde meydana gelen geri dönüşümsüz tıkanmanın bir sonucu olarak değerlendirilmiştir. Bu nedenle polimer boncukların yüksek olmayan havalandırma koşulunda da ilave membran sıyırıcı özellikleriyle biyofilm önleme adına ek olumlu etki ortaya koyması kritik öneme sahiptir. Havalandırma koşulları ve polimer boncukların ortak kullanımı ve tasarlanan işletme koşullarına göre optimizasyonu biyotıkanmanın kontrol altına alınması ve havalandırma maliyetlerinde iyileşmeye neden olacaktır.

Bütün parçacıklar dairesel düğüm çizgisini izleyerek belirtilen sürelerde yörüngenin yaklaşık olarak ¼, ½, ¾ ve 1 oranındaki kısımlarını kat etmişlerdir. t=400 ms anında 0.55 mm çaplı parçacık yaklaşık olarak iki turu tamamlarken, diğer parçacıklar sürüklenme kuvvetinden dolayı çizgisel hızlarını kaybetmekte ve düğüm çizgisinin en alt noktasında ayrışarak tuzaklanmaktadır.
Relative Localization of Wireless Sensor Nodes by Using the RSSI and ToA based distance estimations
Authors: TAMER Özgür
Published: October 2023

Wireless sensor network is a popular area for both academic research and commercial applications. A wireless sensor network is made up of several sensor nodes connected over various wireless infrastructures such as Wi-Fi, Bluetooth, ZigBee, or WiMAX. Determining the relative or absolute position of the sensor nodes is essential information for many applications. In this work, we present a novel method for estimating the position of sensor nodes using the Received Signal Strength Indicator and Time of Arrival metrics of the preferred wireless communication infrastructure. Localization results based on both of the metrics and comparison of them with respect to distance between the nodes are presented, and a novel combined method using both the RSSI and ToA based distance estimations is presented. The proposed method estimates the position of the WSN using both methods, but the result of a single method is preferred depending on the distance between the nodes since within the first 5 m. The RSSI based method is superior to ToA and for farther distances ToA outperforms RSSI. The measurement results show that the combined method reduces the estimation error and performs better than both methods it is based on.
Site Response Predictions at Atakoy Downhole Array
Authors: GUZEL Yusuf , GÜZEL Fidan
Published: October 2023

Site response analyses are seen to be the reliable way of reproducing and predicting earthquake input motions. The analyses are generally performed by adopting equivalent linear or nonlinear approaches solving the problem in time or frequency domains. Instrumented geotechnical downhole arrays, in this regard, are very important as to obtaining earthquake data through the soil deposits. This data can eventually be used to verify the approaches developed for site response analyses. In this study, the input motions of the 24.05.2014 (Aegean) earthquake event recorded at relatively recently installed Atakoy geotechnical downhole array are assessed. Moreover, the recorded input motions at the bottom bedrock level of the downhole array are simulated in the East-West and North-South directions. The site response analyses are conducted based on frequency domain equivalent linear approach. The peak ground acceleration and the spectral accelerations of the predicted input motions are compared with the recorded ones at 70 m, 50 m, 25 m and at the ground surface. The results indicate that the spectral acceleration predictions can be simulated well until the depth of 50 m. At 25 m and at ground surface, the predictions are always greater than the recorded one. However, the predictions still exhibits good indication of actual values in the North-South direction. In terms of peak ground acceleration and shear strain profiles, the predictions display the soil layers featured with different soil properties. The equivalent linear approach appears to be suited reasonably well in site response analysis.
Flechtenflora der Dauner Maare (Vulkaneifel) – Erstnachweis von Cyphelium tigillare in Rheinland-Pfalz
Authors: Oster Julia , Killmann Dorothee , Fischer Eberhard
Published: October 2023

Im Zeitraum von Juli bis September 2018 wurde im Gebiet der Dauner Maare eine Kartierung der Flechten durchgeführt. Hierbei konnten insgesamt 90 verschiedene Flechtenarten dokumentiert werden, darunter 57 Krustenflechten, 27 Blattflechten und 6 Strauchflechten. In Bezug auf die Artenvielfalt ist das Weinfelder Maar mit 61 dokumentierten Flechten das Maar mit der größten Diversität. Am Schalkenmehrener Maar wurden 57 Flechtenarten nachgewiesen. Das Gemündener Maar ist mit nur 37 gefundenen Arten das Gebiet mit der geringsten Diversität. Besonders bemerkenswert ist der Fund von Cyphelium tigillare auf Totholz am Schalkenmehrener Maar. Diese Art konnte zum ersten Mal für Rheinland-Pfalz nachgewiesen werden. Die intensive Beweidung am Weinfelder Maar wirkt sich extrem negativ auf das Vorkommen von Flechten aus. So konnte die von LAMBINON (1964) dokumentierte und vom Aussterben bedrohte Blattflechte Peltigera lepidophora nicht mehr nachgewiesen werden.
Steppenelefantenfaunen der jüngeren Rheinterrassen zwischen Köln und Xanten
Authors: Lanser Klaus Peter
Published: October 2023

Die Merkmale der Backenzähne von Steppenelefanten aus verschiedenen Zonen der Niederterrasse und der Krefelder Terrasse zeigen deutliche regionale Unterschiede: Treten im Bereich der Niederterrasse außerhalb des Verbreitungsbereiches der Gletscher des nordischen Inlandeises, neben Zähnen einer hochentwickelten Evolutionsstufe, gehäuft auch solche mit gering evolutionierten Merkmalen auf, die auf Elefanten der drittletzten (Elster-) Eiszeit, der vorletzten (Holstein-) Warmzeit und der vorletzten (Saale-) Eiszeit hindeuten, so fehlen diese weitgehend innerhalb der von den Gletschern überdeckten Zone. Lediglich einzelne Elefantenbackenzähne aus diesem Bereich zeigen Merkmale die auf ein Entwicklungsstadium älter als die Saale-Eiszeit hindeuten. In der Mehrzahl signalisieren sich hier spät saalezeitliche, eem- und weichselzeitliche Schichten durch ihre Fossilführung. Ähnliches lässt sich auch im Bereich der nördlichen und nordöstlichen Kempener Platte beobachten, die Teil der Krefelder Terrasse ist. Hier in unmittelbarer Nähe zum ehemaligen Gletscherrand, wurden Sedimente mit einer Führung von holstein- und saalezeitlichen Elefantenbackenzähne offensichtlich ebenfalls erodiert. Neben gering evolutionierten Backenzähnen von Mammuthus trogontherii aus der frühen drittletzten Eiszeit, fanden sich hier lediglich Backenzähne von hoch entwickelten M. primigenius des jüngeren Eiszeitalters. Die in diesem Bereich anstehenden interglazialen Kempener Schichten können damit nicht in der Holstein-Warmzeit und die Krefelder Terrasse in deren Hangenden demnach auch nicht in der Saale-Eiszeit zur Ablagerung gekommen sein. Eine Entstehung der Kempener Schichten in der Eem-Warmzeit und der Krefelder Terrasse in ihrem Hangenden in der Weichsel-Eiszeit ist daher naheliegend. Eine Sonderstellung nehmen die Neuwerker Schichten, im westlichen Bereich der Kempener Platte ein. Hier lassen sich Backenzähne von gering evolutionierten Steppenelefanten nachweisen, die sowohl Merkmale von M. trogontherii der frühen Elster-Eiszeit, als auch von M. intermedius der Holstein-Warmzeit und der Saale-Eiszeit aufweisen. Offensichtlich hat die größere Entfernung zum ehemaligen Gletscherrand die hier anstehenden Sedimente vor der Erosion durch Schmelzwässer der Gletscher bewahrt. Backenzähne von M. primigenius des jüngeren Pleistozäns treten hier nur vereinzelt auf. Das bedeutet, innerhalb der Krefelder Terrasse, im Bereich der Kempener Platte, sind interglaziale Schichten sowohl der Holstein- als auch der Eem-Warmzeit vorhanden. Überlagert werden diese von Sedimentabfolgen der letzten Eiszeit, wobei sich im Falle der Neuwerker Schichten in deren Hangenden auch Reste von saalezeitlichen Sedimentabfolgen erhalten zu haben scheinen.
Makrozoobenthos der Swist und seine Veränderung zwischen 1957 und 2017
Authors: Ehlert Thomas
Published: October 2023

Veränderungen der Makrozoobenthos-Lebensgemeinschaft und der Wasserbeschaffenheit der Swist in den vergangenen sechs Jahrzehnten werden auf Grundlage früherer Veröffentlichungen, Daten des Elektronischen Wasserwirtschaftlichen Informationssystems (ELWAS) und eigener Untersuchungen dokumentiert. Der ehemalige Artenreichtum der unbelasteten Swist lässt sich heute anhand weniger historischer Belege nur noch erahnen. Bis Mitte des 20. Jahrhunderts hatte sich die Lebensgemeinschaft in Folge von Abwassereinleitungen bereits deutlich verändert. Auf dem Höhepunkt der Gewässerverschmutzung etwa um 1970 war die Swist in Nordrhein-Westfalen biologisch weitgehend verödet. Erst mit dem Ausbau der Kläranlagen ab Ende der 1970er Jahre setzte langsam eine Erholung ein. Seit rund 20 Jahren hat sich die Wasserqualität der Swist auf der gesamten Länge soweit verbessert, dass eine Wiederbesiedlung mit heimischen und neozoischen Makrozoobenthos- Arten eingesetzt hat. Ausgehend von Quellpopulationen in der Erft, in den Zuflüssen im Oberlauf sowie in benachbarten Fließgewässern ist die 44 Kilometer lange Swist innerhalb von 20 Jahren von rund 40 gewässertypischen Wasserinsektenarten wiederbesiedelt worden. Die Entwicklung ist bis heute nicht abgeschlossen.

Published: October 2023

Die Trinkwassergewinnung stellt nicht nur eine extensive Form der Landnutzung dar, sie ist auch mit Restriktionen hinsichtlich des landwirtschaftlichen Einsatzes von Dünge- und Pflanzenschutzmitteln innerhalb der Schutzgebietszone verbunden, welche zur Entstehung und zum Erhalt von für den Naturschutz wertvollem, artenreichem Magergrünland führen können. Nach Beendigung der Trinkwassergewinnung unterliegen diese Flächen oft der Gefahr einer weniger umwelt- und naturschutzverträglichen Landbewirtschaftung, so dass eine administrative Sicherung solcher wertvollen Flächen sinnvoll ist. Dabei gilt es zu ermitteln, welche Schutzgüter im betreffenden Gebiet vorkommen und welche Qualitäten wertgebend für ein Schutzgebiet sind. Anhand des vorliegenden Beitrages soll dargestellt werden, welche naturschutzfachlichen Wertigkeiten die Flächen einer ehemaligen Trinkwassergewinnung in der Ruhraue in Bochum-Stiepel aufweisen und wie sie planerisch einzuordnen sind, damit sie durch adäquate Pflege- und Entwicklungsmaßnahmen langfristig erhalten werden können. Des Weiteren soll die floristische und vegetationskundliche Bedeutung des vorhandenen Grünlandes im regionalen Kontext für den Bochumer Raum und für das Ruhrgebiet dargestellt werden. Dabei werden aus pflanzengeographischer und naturschutzfachlicher Sicht bemerkenswerte Taxa der Gefäßpflanzen gesondert kommentiert und der naturschutzfachliche Wert des Gebietes diskutiert.

Published: October 2023

In dieser retrospektiven Studie wurden 47 Patienten mit einem histologisch nachgewiesenen Analkarzinom und im Anschluss aufgetretenen Rezidiv nach Beendigung der Radiochemotherapie und hinsichtlich der Risikofaktoren für das tumorfreie, sowie das Gesamtüberleben ausgewertet. Auffällig in dieser Patientenkohorte war der hohe Anteil an männlichen Patienten (68,1 %), an HIV-positiven (36,2 %) sowie an Patienten mit nachgewiesenem Lymphknotenbefall bei Erstdiagnose (72,3 %). Als signifikante Risikofaktoren für das tumorfreie Überleben wurden ein Primärtumor ab ≥ T3-Kategorie (Hazard-Ratio 1,87), ein Karnofsky-Performance-Status ≤ 80 % vor Beginn der Radiochemotherapie (Hazard-Ratio 3,25), sowie das initiale fehlende therapeutische Ansprechen der Radiochemotherapie (Hazard-Ratio 5,9) festgestellt. Auffällig war, dass kein signifikanter Einfluss bzgl. des biologischen Geschlechts, des Gradings, der N Kategorie oder des Alters ermittelt werden konnte. In Bezug auf das Gesamtüberleben der Patienten ergaben sich folgende signifikante Risikofaktoren: eine T-Kategorie ≥ T3 (Hazard-Ratio 4,091), ein hohes UICC-Stadium (Hazard Ratio 2,89 für Stadium IIIC), das fehlende initiale therapeutische Ansprechen der Radiochemotherapie (Hazard-Ratio 9,59), ein Karnofsky-Performance-Status ≤ 80 % (Hazard-Ratio 12,23). Ein protektiver Faktor stellte ein längeres tumorfreies Überleben (Hazard-Ratio 0,935) dar. Die Auswertung des gesamten und des tumorfreien Überlebens hinsichtlich des Befallsmusters der Rezidive ergab, dass mit zusätzlich zum lokalen Rezidiv nachgewiesenem lokoregionären Rezidiv und Fernmetastasen sich sowohl das tumorfreie Überleben (Ein-Jahres-tumorfreies Überleben 52,9 ± 12,1 % vs. 15,0 ± 8,0 %) als auch das Gesamtüberleben (5-Jahres-Gesamtüberleben 75,0 ± 12,5 % vs. 0,0 %) signifikant verringerten. Im Vergleich der Merkmale der Patienten mit und ohne nachgewiesenen Fernmetastasen ergab sich ein signifikanter Unterschied in Bezug auf den Anteil der Tumore ≥ T3 (75 %). In der Untergruppe, die mittels abdominoperinealer Rektumexstirpation therapiert wurde, konnte kein signifikanter Unterschied in Bezug auf die rpT-Kategorie, R-Klassikfikation, Pn-, V- und L-Klassifikation festgestellt werden.

Authors: Stechyshyn Myroslav , Dykha Aleksandr , Oleksandrenko Victor
Published: October 2023

The effect of anhydrous nitriding in a glow discharge on microhardness, phase composition, and wear resistance of long holes in steels C45, 37Cr4, and 41CrAlMo7 with direct current supply and in cyclically switched discharge (CSD) was studied. Nitriding was carried out on a UATR-1 anhydrous nitriding unit with a discharge chamber diameter of 400 mm and a working height of 700 mm. Anhydrous nitriding in a glowing discharge was carried out at a temperature of 560 °С, a voltage of 730 V, a pressure in the chamber of 120 MPa, and the nitriding duration was 6 h. It was established that using holes with a relatively small diameter of glow discharge in a cyclically switched discharge for nitriding creates conditions for obtaining modified layers with higher physical, mechanical, and tribological characteristics. The results of microhardness measurement and their comparison with X-ray phase analysis data confirm the formation of ε, γ, and α phases during nitriding along the entire height of the samples placed in the experimental model. The tests carried out in the dry friction mode showed an increase in the wear resistance of samples made of steel C45, 37Cr4, and 41CrAlMo7 during nitriding in a cyclically switched discharge. To achieve 100 μm wear of 41CrAlMo7 steel during nitriding in CSD, 1400 m of friction path and 1000 m – during nitriding with direct current is required. It was established that using long holes of a glow discharge with different types of power for nitriding creates conditions for obtaining modified layers with variable characteristics. Nitriding of holes with a relatively small diameter of a glow discharge with a different power supply creates conditions for obtaining modified layers with different physicomechanical and tribological characteristics.

The present study aims at valorizing the stem of Hibiscus sabdariffa, a by-product of agriculture in Benin. This natural resource, abundant in tropical countries, including Benin, was until now considered as a biodegradable waste and treated as such. However, it possesses adsorption properties that can be exploited through its transformation into activated carbon for various uses, including water pollution control. For this purpose, activated carbon has been developed from Hibiscus sabdariffa stems chemically impregnated with phosphoric acid. The pseudo second-order model predicts the kinetics of phenol adsorption on the activated carbon produced. The thermodynamic study of the adsorption process of phenol shows that it is exothermic and spontaneous with an ordered structure on the surface of the material.

This article investigates the innovative fusion of cellular physiology and forensic anthropometry, revealing a promising synergy for increasing investigative capacities, particularly in resource-constrained environments. To gain essential information about identifying people, morphological analysis has traditionally been utilized in forensic anthropometry, a well-established field that measures human skeletal remains. To better understand post-mortem cellular alterations, new forensic investigational paths have been made possible by recent developments in cellular physiology. This interdisciplinary approach has great promise in low- and middle-income countries (LMICs), where forensic resources are frequently scarce. Investigators can gather crucial information about the post-mortem period, the cause of death, and probable signs of trauma or pathology thanks to the integration of cellular physiology with forensic anthropometry. This strategy utilises methods like immunohistochemistry, gene expression analysis, and cellular bioinformatics to enable a more nuanced and precise reconstruction of events leading up to death. The actual use of this interdisciplinary paradigm in LMIC environments is elucidated in this paper. It tackles issues with accessibility to technology, training, and infrastructure while suggesting flexible ways to close existing gaps. This strategy is positioned to strengthen investigative capacities in areas where they are most urgently required by stressing cost-effective methodologies and the use of open-source resources.We show the concrete effect of this integration on actual investigations through a number of case studies and comparative analyses. When compared to using only standard anthropometric methods, the results reveal a significant improvement in accuracy, precision, and efficiency. Additionally, this interdisciplinary strategy may make it easier to create extensive forensic databases, enabling more effective identification attempts and aiding in the solving of unsolved cold cases.

LGBTQIA is an acronym for lesbian, gay, bisexual, transgender, queer/questioning (ones sexual or gender identity), intersex, and asexual/aromantic/agender. These terms are used to describe a persons sexual orientation or gender identity. The term LGBT is in use since the 1990s, the term is an adaptation of the term LGB, which replaced the term gay in reference to the LGBT community beginning in the mid-to-late 1980s. Many activists believed that the term gay community did not accurately represent all those to whom it referred. Section 377 of the Indian Penal Code is a section of the Indian Penal Code introduced in 1861 during the British rule of India. Modelled on the Buggery Act of 1533, it makes sexual activities against the order of nature illegal. On 6 September 2018, the Supreme Court of India ruled the decriminalisation of Section 377 which has led to the publics acknowledgement of the third gender in India. Time and again media have played role in creating awareness about the concerns related to the community. Many films, television shows, and OTT platforms have also shown content related to the LGBTQIA+. In recent times, majority of viewers have shifted to OTT platforms and one can witness that with benefits of OTT, it has become easy for content producers to highlight any topic of interest and relevance. Many series on famous OTT platforms are presenting LGBTQIA+ relations in an undisguised manner so that the society also recognises LGBTQIA+ communitiesall across the world, their rights, and their culture and that this be marked by a spirit of resistance and acceptance as opposed to an attitude of shameby creating an awareness in the mind of the viewers. The study aims to find out the representation of LGBTQIA+ on Amazon Prime Video and their influence on society. This is exploratory research. The content analysis of web series on Amazon Prime Video has been done to understand the type of content shown in web series and in-depth interviews have been conducted to understand the influence of such content on the LGBTQIA+ community members.

Historically, in the European imagination, India was a place that existed outside of history. The German philosopher G.W.F.Hegel wrote that India-with its psychology, religion, caste-system, and holy men - existed in a dream-like state. However, India, like every other place in the world, has never existed outside of history as an exotic dreamland. It has had itsown complex economic, social and political things going on regardless of whether the West was aware of it. India is a dream of the West. Being a maelstrom of human, social, and spiritual contradictions, India has always attracted many western filmmakers. In order to give a glimpse of its ancient concepts, complex reality and dynamism the contemporary global view of filmmakers on the lifestyle and the diversity of this country has been proposed. Many westernfilmmakers, including those from France, have had a desire to express themselves often with talent.The aim of this research paper is to bring forth their insight into life and culture of India. An analysis of how Westerners have stereotyped Indian concepts or accounted for the profound changes inIndian societyin their films has been done.

Background: Although the analgesic effect of sucrose on new- borns is well established, little is known about whether these solutions are effective in reducing procedural pain in infants beyond the newborn period. The purpose of this study was to determine the effect of sucrose solution given orally on infant crying times and measure the distress in a 16â€“19-month age group. Methods: A total of 439 healthy infants and children receiving their regular vaccinations aged between 16 and 19 months attending the of the Department of Pediatrics were recruited and randomized for the study . Overall, 360 infants were analyzed. These infants were born at term, were of normal birth weight, were otherwise healthy, and were required only routine well-child care. Results: A total of 360 healthy, 16â€“19-month-old infants attending for their immunizations with intramuscular injection were randomized to receive 2 mL of a 75 % sucrose solution, a 25 % sucrose solution or sterile water 2 min before injections. Infants receiving a 75 % sucrose solution had significantly reduced total crying times and Childrens Hospital of Eastern Ontario Pain Scale scores (CHEOPS) compared with infants in the control and 25 % sucrose solution groups (p<0.001). Conclusion: Sucrose solution reduces infant distress and is safe and clinically useful even for 16â€“19-month-old infants.
A compilation of common crossbill Loxia curvirostraL., 1758 ring-recovery data from the Iberian Peninsula and other European regions
Authors: Hidalgo Juan Carlos , Baonza Elena
Published: October 2023

In November 2021, a female common crossbill ringed in Switzerland was found in the Sistema Central mountain range, within the administrative border of the Community of Madrid (Spain). This is an unusal record due to the lack of data on irruptions of this species from central or northern Europe in the centre of the Iberian Peninsula. In this study, we have compiled all the existing common crossbill ring-recovery data from Iberia and other European regions. Our results show that common crossbill populations in the Iberian Peninsula are mainly sedentary, with limited movements across the different pine forest masses in search of food. In contrast, northern European common crossbill populations develop long distance migratory movements that may involve a large number of individuals following a NE-SW axis that, in an irregular manner and depending on the year, can arrive in the Iberian Peninsula in mid-August or September, where they may remain for several years before returning to their places of origin. In the Iberian Peninsula, these crossbills seem to use the pine species available as a trophic resource according to their ecological speciation, including species not present in their regions of origin.

Greenhouse Salt Tunnel as Innovation to Create Salt Production in the South Coast Malang Regency, Indonesia
Authors: Amin Abd. Aziz
Published: October 2023

Seawater is one of the potential resources in Indonesia. One of the commodities that can be produced from seawater is salt. Salt production in Indonesia is done mainly by evaporating seawater. However, weather problems are one of the obstacles to salt production. Alternative innovation to overcome weather problems in salt production is the Greenhouse Salt Tunnel (GST). The application of this innovation allows salt production to be carried out throughout the year. Most salt businesses in East Java are located on the north coast of East Java, while there is no salt production on the South Coast of East Java. One of the locations in East Java that can be used for salt production is the South Coast of Malang Regency. However, studies analyzing the need for innovation to create salt production in the South Coast of Malang Regency have never been reported. This study aimed to analyze the application of GST innovation to create salt production in the South Coast of Malang Regency. The methodologies were analyzing the suitability index of salt production sites, soil elevation analysis, wind direction and speed, and construction requirements for GST. The results show that Gajahrejo Village is very suitable for salt production. The salt production can be conducted using 12 GST constructions on a 2000 m2 area. According to the results of this study, salt production in the south coast area of Malang Regency can be created using the application of GST innovation.
