3,4-Dimetoksifenilasetonitril’in Kuaterner Amonyum Tipi Dimerik Yüzey Aktif Maddeler İle Faz Transfer Katalizli Siklopentilasyonu
Authors: Şuekinci Yılmaz Ayşen , Boz Mesut
Published: December 2024

Bir organik sentezde genellikle uygun bir baz ile C, O, N gibi atomlara bağlı asidik karakterde bir protonun koparılması gerekir. Bu amaçla uygun baz ve çözücü sisteminin seçimi önemlidir ki sıklıkla güçlü bazlar ve kurutulmuş çözücüler kullanılması gerekir. Kimya Endüstrisinin gelişmesiyle birlikte artan çevre sorunları sebebiyle, kimyasalların ve kimyasal proseslerin çevreye olumsuz etkilerini azaltmayı veya ortadan kaldırmayı amaç edinen "Yeşil Kimya" kavramı gitgide önem kazanmaktadır. Daha ılımlı bazlar, daha zararsız çözücüler içeren çevre dostu organik sentez prosedürlerinin uygulanması hayati derecede önemlidir. Bu prosesler arasında farklı fazlarda çözünebilen reaktiflerin etkileşmesini sağlayarak, reaksiyonların daha kısa sürede ve yüksek verimlerle gerçekleşmesini sağlayan faz transfer katalizli reaksiyonlar öne çıkmaktadır. Faz transfer katalizi sistemleri enerji sarfiyatını azaltmanın yanı sıra, yan ürün oluşumunu da baskılayarak saflaştırma aşamasında daha az çözücü kullanılması gibi ekonomik avantajlarda sunmaktadır. Organik sentezlerde sıklıkla bir kuarterner amonyum tuzu olan tetrabütilamonyum bromür (TBAB) faz transfer katalizörü olarak kullanılır. Son yıllarda kuaterner amonyum bileşiklerinin dimerik yapıda olanları monomerik olanlara göre üstün yüzey aktif özellikleriyle dikkat çekmekte ve bu bileşikler “gemini sürfaktan” olarak adlandırılmaktadır. Bilim insanları bu bileşiklerin fizikokimyası ve yüzey aktif özellikleri ile ilgili çok sayıda araştırma ortaya koymuşlardır. Fakat bu bileşiklerin tetrabütilamonyum bromür gibi faz transfer katalizli organik sentezlere uygulanması ile ilgili çalışmalar sınırlıdır. Bu çalışmada sekiz farklı dimerik kuaterner amonyum bileşiği sentezlenerek, bu bileşiklerin 3,4-dimetoksifenilasetonitril’in siklopentilasyonunda faz transfer katalizörü olarak davranışı incelenmiştir. Dimerik sürfaktanların 3,4-dimetoksifenilasetonitril’in siklopentilasyon reaksiyonunu geleneksel faz transfer katalizörü TBAB kadar iyi verimlerle katalizlediği, hatta bazı dimerik surfaktanların TBAB’den daha yüksek verimler oluşturduğu tespit edilmiştir.
Tunable ultra-wideband band-stop filters based on a metal-insulator-metal waveguide with triangle resonators
Authors: Korkmaz Semih
Published: December 2024

This study introduces the design and analysis of ultra-wideband band-stop filters based on a metal-insulator-metal (MIM) waveguide with triangle resonators. The optical features of the filters are determined numerically. Transmission values and field distributions have been obtained. To show the tunability of the resonances of the filters, parameter sweep analysis has been done. This feature provides the shifted wideband bandwidths from visible to mid-infrared regimes. The highest bandwidth is 859 nm for band-stop filtering in this work. Higher bandwidths can be achieved by increasing the number of resonators adjacent to the waveguide. This research offers the potential to improve the filtering capabilities of optical devices through the use of high-efficiency MIM waveguide-resonator systems.

Authors: Çavuş Barış , Aktaş Mustafa
Published: December 2024

It is very important to operate the motors used in electric vehicles above the rated speed. In order to operate electric motors with very high speed, the flux must be decreased in a controlled way. The Model Predictive Control (MPC) approach was employed in this study to reduce the flow. In the flux weakening area, the induction motor's performance without a speed sensor has been evaluated. As a result of the study, both the speed sensorless performance of the MPC based flux weakening control has been examined and the performance of the Model Reference Adaptive System (MRAS) and the Sliding Mode Observer (SMO) in very high speed region over nominal value has been evaluated. It has been successfully demonstrated that MPC-based flux weakening control with two speed observers can be achieved based on the current, speed, flux, and torque data collected through the simulation study. In addition, as a result of the study, it is seen that SMO has given better results.

Revision of Marchantiana (Caloplacoideae, Teloschistaceae) – a misconceived lichen genus
Authors: Søchting Ulrik , Arup Ulf
Published: December 2024

The genus Marchantiana has been a victim of changeable concepts, partly due to erroneous DNA sequences published with its description. Based on new molecular sequencing, new chemical analyses and additional field work, mainly in Patagonia, Tasmania and New Zealand, we present a new taxonomic classification for the genus and related species. M. michelagoensis is confirmed to belong to Marchantiana, and the genus Streimanniella, for which this species was the generic type, is synonymized with Marchantiana. We combine Caloplaca haematommona, C. magnetensis, C. tomnashii and C. phaeocincta into Marchantiana as M. haematommona, M. magnetensis, M. tomnashii and M. phaeocincta, respectively. A new genus Taedigera is described to cater for three previous Marchantiana species and one Caloplaca species, with the new names T. pyramus, T. ramulicola, T. subpyracea and T. epibrya, respectively. Two species, T. flammea and T. gallowayi, both twig epiphytes from New Zealand, and one species, M. tasmanica, from Tasmania, are described as new to science based on molecular and secondary chemical characters. Marchantiana burneyensis, M. kalbiorum and M. seppeltii are excluded from the genus Marchantiana based on newly generated sequences of type material. A key is provided to the species groups in Patagonia, Tasmania and New Zealand.

Published: December 2024

Charge-sensitive infrared phototransistors (CSIPs) based on GaAs/AlGaAs quantum well structures permit highly sensitive detection of radiation in the wavelength range of 10–50 μm. Despite this excellent sensitivity, their quantum efficiency remains limited to approximately 20%. In this study, we first developed a cryogenic measurement system for evaluating the quantum efficiency of CSIPs using a calibrated thermal radiation source (a heated chip resistor) in a liquid-helium-free refrigerator. Using this measurement system, which sufficiently suppresses background infrared radiation, we next attempted to enhance the quantum efficiency by combining the CSIP with a hemispherical mirror composed of a germanium hemispherical lens with a metal-coated convex surface. Mounting the hemispherical mirror on the CSIP surface improved the quantum efficiency to 35%. Moreover, by covering the front side of the CSIP, the mirror further suppressed the infrared background radiation from the surrounding environment, reducing the detectable photon flux limit to

Published: December 2024

Hole spins in silicon quantum dots (QDs) are a promising candidate for fault-tolerant quantum computing. To achieve the high-fidelity readout and high coherence required for fault tolerance, the evaluation of spin-blockade and state lifetimes is important because they can limit the qubit fidelities. In this study, we characterize these two figures of merit of many-hole qubits in silicon QDs. We report a spin-blockade lifetime of 5.1 μs, which is comparable with the values reported previously, and a spin-state lifetime of 0.91 ms, which is longer than the one measured in a few-hole silicon QD in a previous study. We furthermore provide insights into a many-hole spin state based on the estimated tunneling rate ratio.

Published: December 2024

The inclined structures of threading screw dislocations (TSDs) in silicon carbide (SiC) were analyzed to observe dislocations located deep inside a crystal using X-ray topography (deep XRT). In the deep XRT of a 00012 diffraction, the strain fields of TSD core-lines from the sample surface to a depth of 90 μm were projected on a detector. We propose a method for analyzing the inclined structure of a real TSD from a TSD projected onto a detector. The inclined direction and angle of the real TSD were estimated by correcting the terminal coordinate of the projected TSD core-line. Furthermore, the mixed components of the Burgers vector of TSDs were verified using a discriminant method based on 〈11

thin films (x = 0.750, 0.852, and 0.918) investigated by oil-immersion Raman spectroscopy. The sample temperature was elevated by increasing laser power and estimated using the relation between Raman shift ω and temperature T (dω/dT) of Ge-Ge vibration mode. The broad peaks observed from all the Ge-rich SiGe thin films shifted toward the lower wavenumber side with increasing laser power. We confirmed that dω/dT of the broad peak differs from the Ge-Ge vibration mode and changes with increasing Ge fraction. In addition, we found that the correlation between the Ge fraction and the peak intensity ratio of the broad peak and the Ge-Ge vibration mode is almost the same at various laser power conditions.

crucial roles in assessing tumor extension, while histopathological analysis informs prognosis and treatment planning. Surgical resection remains
the cornerstone of treatment, with endoscopic techniques emerging as effective alternatives, particularly for advanced cases. Adjuvant radiation
therapy is standard, although its necessity in early-stage cases continues to be debated. Chemotherapy may be beneficial for advanced disease and
is tailored based on individual patient factors. Despite a generally favorable prognosis, the risk of local and regional recurrence underscores the
importance of long-term follow-up. This article emphasizes the need for accurate diagnosis, comprehensive treatment planning, and ongoing
patient monitoring to optimize outcomes in esthesioneuroblastoma management.

Published: December 2024

Background: Tibial plateau with their articular surface forms major part of the knee joint, plays an important role in weight transmission and
mobility. The tibial plateau fractures account for 1% to 2% of all bone fractures. In the event that these intra/peri articular fractures go untreated,
there is significant risk of ligamentous instability, axis malalignment, articular incongruity, malunion and varus collapse of medial condyle. Aim
was to assess the anatomical reduction of articular surface of upper end of tibia perfectly by operative treatment with dual plate osteosynthesis.
Methods: The study was conducted on 20 patients admitted in the department of orthopedics KMCRI Hubli, with diagnosis of Schatzker fracture
type V and VI treated with dual plate osteosynthesis. The patients were followed up for a minimum period of six months and clinical, functional and
radiological progression of fracture union was studied by using Honkonen Jarvinen Criteria. Our stu Results: dy reported Honkonen Jarvinen

Radiological outcome showed 87% excellent, 13 % good results. Dual plate osteosynthesis is ideal for Conclusion: all Schatzker type V and VI
with appropriate timing of surgery and understanding the anatomy, LCP system, appropriate technique with dual incision, the complication can be
minimized, giving excellent to good results.
AN UNUSUAL PRESENTATION OF A POST- OPERATED CASE OF INTUSSUSCEPTION
Authors: Mukherjee Debraj , Mishra Poulami
Published: December 2024

This case report details the clinical journey of an 11-year-old girl who presented to the emergency department with abdominal distension, vomiting,
fever, and abdominal pain for last 3 months following recent surgery for ileo-colic intussusception 4 months ago. During the surgery manual
reduction was performed, no definite Pathological lead point(PLP) was identified; few “insignificant” mesenteric lymph nodes were found.
Imaging studies revealed a large complex cystic mass, ascites, and left-sided pleural effusion. Laboratory findings indicated severe anemia and
significantly elevated LDH. Initial differential diagnoses included mixed germ cell tumor and non-Hodgkin lymphoma, but a core biopsy
ultimately confirmed Burkitt lymphoma. The patient's condition worsened, leading to the development of tumor lysis syndrome, requiring urgent
management .Approximately six months later, she developed a splenic abscess that ruptured spontaneously, necessitating splenectomy and
resection of the sigmoid colon with anastomosis. Following surgery, the child experienced complications including a high-output enteric fistula,
which ultimately led to her demise. Many cases after intussusception present with Sub acute intestinal obstruction due to either adhesive
obstruction or due to recurrent intussusception due to recurrence of Pathological lead point (PLP).However in our case no PLP was identified
during surgery. Were the 'insignificant' mesenteric lymph nodes a precursor lesion? Or was the rapidly growing BURKITT LYMPHOMA a de novo
lesion? This report highlights Burkitt's lymphoma as a rare cause of intussusception in the atypical age group .
DRILLING INTO THE FUTURE: A REVIEW OF SELF-DRILLING SCREWS IN MAXILLOFACIAL CARE
Authors: Sree Harika Thatavarthi
Published: December 2024

As the number of road traffic accidents are increasing nowadays, the ease of using armamentarium is also being precisely modified. One such
advancement in oral and maxillofacial surgery is the use of self-drilling screws. Self-drilling screws (SDS) are increasingly favored for their
efficiency and convenience. They eliminate the need for pre-drilling, reducing surgical time and minimizing tissue damage. Self-drilling screws are
particularly valuable in procedures requiring bone stabilization, such as intermaxillary fixation and miniplate fixation. This article explores the
design, applications, benefits, and limitations of self-drilling screws in oral and maxillofacial procedures.
SCREENING FOR COVID-19 AMONG WORKERS ATTENDING MEDICAL EXAMINATIONS UNDER OCCUPATIONAL HEALTH SERVICE OF AN OPEN-CAST IRON ORE MINE IN JHARKHAND: A CROSS-SECTIONAL STUDY
Authors: Chatterjee Amala Sankar , Kumar Dhirendra
Published: December 2024

Introduction: The world is going through an unprecedented phase of COVID-19. Safe and healthy workplace is integral part of Occupational
Health. Unsafe work practices anywhere are a constant threat, both for our health and sustainable business of an organization. Screening involves
testing asymptomatic individuals who do not have known or suspected exposure to COVID-19. There is no screening strategy to exclude anyone
contagious entering workplace. Materials & Methods: A cross-sectional study was conducted through screening for COVID-19 by Rapid
Antigen Test (RAT) or RTPCR test (True Nat) of 860 workers who appeared for initial and periodical medical examinations (IME / PME) under
Occupational Health Service of a mine hospital in Jharkhand. Study period: December 2020 to May 2021. Chi-Square test was used for statistical
analysis. Results: Study revealed, mean age of employees 32.09±8.42 years. Total 28 (3%) workers were tested COVID-19 positive, mostly
asymptomatic (64%). Among COVID positive cases, 16 (57%) were in age of 21-30 years and 25 (89%) were male. Among the symptomatic cases
(n=10), 50% presented with generalized weakness. 20% workers presented with fever, 20% with cough and 10% workers had sore throat.
2 Generalized weakness was significantly associated (p< 0.05) with COVID positive cases (x =8.944, p=0.003). Conclusions: Screening is
important part of health check-up to maintain safety in workplace, especially in time of pandemic. Most of the affected persons were asymptomatic
and would have been caused of more positive cases at workplace, community at large. Our study emphasized the need for implementation of
population-based screening programs at shop floors to prevent spread of COVID-19 among the mining workers.
MURRAYA KOENIGII LEAVES EXTRACT FABRICATED NANOTEXTILE AS HOLY GRAIL FOR FEMALE HYGIENE
Authors: Bhagat Bhairavi , P. Naik Jignaben
Published: December 2024

Good feminine hygiene is important for preventing infections and other health issues. Medical literature has not given enough attention to intimate
feminine hygiene, which makes education a priority. Inappropriate intimate hygiene can result in problems like urinary and reproductive tract
infections. According to CDC these infections are treated with over the counter drugs, which lead to antimicrobial resistance. An incongruous level
of antimicrobial-resistant microbes has been reached worldwide and is threatening global public health in the form of a silent pandemic. To deal
with those microbes call for an advanced approach. Nanotechnology is widespread in the present era and the use of small particles known as
nanoparticles is a part of nanomedicine, involving diagnosis and treatment of diseases. Antimicrobial nanotextiles are fabrics that have been treated
to kill or inhibit the growth of microorganisms. Present study dealt with synthesis of silver nanoparticles (SNP) in an eco-friendly way by using
leaves of Murraya koenigii. These nanoparticles were characterized and coated on selected fabric by the Pad-Dry-Cure method. The coated fabric
appears darker in color, indicating the deposition of SNPs and coating on the fabric was further confirmed by Scanning Electron Microscopy
(SEM). Various physical parameters of fabric were measured. The thickness of fabric is increased by 1.9%, air permeability and density also
increases by 5.7% & 0.43% respectively, water absorption capacity decreases by 0.15% and there was no difference in Grams per Square Meter
(GSM) of fabric, after coating with SNPs. The antimicrobial activity of the fabric was found against most prevalent urinary tract infection (UTI)
causing bacteria and yeast. The results obtained by this eco- friendly bio-inspired method of SNPs synthesis and coating on fabric may contribute to
advance the application of antimicrobial textile products especially for female hygiene.
Werk maken van straf: De methodiek werkstraffen
Authors: Krechtig Lous
Published: December 2024

De knokkende cafébezoeker, de frauderende directeur, de graffitispuitende 'kunstenaar', de jeugdige overlastbezorger. Hun straf – een werkstraf – maakt ze boos, verontwaardigd. Of ze zijn juist onder de indruk van hun straf. Ze begrijpen dat ze moeten boeten voor wat ze hebben misdaan. Of vinden juist dat de maatschappij hen onrecht aandoet; voelen zich slachtoffer in plaats van dader.

De wereld van de werkstraf is zeer divers. Als het gaat om delict, leeftijd, afkomst, karakters van werkgestraften. De medewerkers van de werkstrafunits van Reclassering Nederland matchen al deze diverse daders aan werkstrafprojecten. Om gedrag te veranderen. Om ervoor te zorgen dat een werkgestrafte niet in herhaling valt; niet opnieuw een glijbaan vernielt, een gezinslid een klap verkoopt of wietplantjes teelt en verkoopt. De werkgestrafte maakt zich nuttig, doet iets terug voor de maatschappij. Een veiliger samenleving is het beoogde resultaat.

Dat gaat niet vanzelf. Een werkstraf tot een goed einde brengen vergt inspanning. Niet alleen van daders, maar ook van de medewerkers van de werkstrafunits. De diversiteit aan daders vraagt om een diverse aanpak in diverse situaties. Een aanpak die recht doet aan het feit dat de werkstraf een straf is. Die tegelijkertijd ook de ruimte laat voor methodisch doordacht en verantwoord ingrijpen, voor de keuze voor het gebruik van de zachte of juist de harde hand.

Kindermishandeling: signaleren en handelen
Authors: Wolzak Adrie
Published: December 2024

Het gezin is niet voor ieder kind een veilige plek: elk jaar weer worden duizenden kinderen mishandeld, verwaarloosd of misbruikt. Hoe zie je aan een kind dat het thuis in de knel zit? En wat doe je als je je zorgen maakt over een kind? Het zijn vragen waar veel mensen die met kinderen werken tegenaan lopen.

Door de Wet meldcode huiselijk geweld en kindermishandeling moeten organisaties en ­professionals die in hun werk met ouders en/of kinderen te maken krijgen, werken volgens een meldcode. Dit is een stappenplan dat zij kunnen gebruiken als ze vermoedens van mishandeling hebben. Onderzoek wijst uit dat hulp-, zorgverleners en leraren die met een meldcode werken drie keer zo vaak ingrijpen als collega’s die zo’n code niet voorhanden hebben.
Met de komst van de Wet meldcode wordt meer dan voorheen van professionals verwacht dat zij alert zijn op signalen die kunnen wijzen op kindermishandeling. Het boek Kindermishandeling; signaleren en handelen biedt mensen die met kinderen werken en kindermishandeling vermoeden, al jaren houvast. Deze geactualiseerde druk is afgestemd op de laatste ontwikkelingen rond de Wet meldcode. Daarnaast treft u een beschrijving aan van de aard, de oorzaken en de gevolgen van kindermishandeling. Ook de signalen van kindermishandeling komen uitgebreid aan de orde. Aan de hand van een stappenplan wordt verduidelijkt wat iemand kan doen die zich zorgen maakt over een kind. Een gesprek voeren met het kind of de zorgen bespreken met de ouders is daar een wezenlijk onderdeel van. Daarom zijn in dit boek aandachtspunten opgenomen om dergelijke gesprekken te voeren.

Dit boek is bestemd voor mensen die werken met kinderen, zoals werkers in de kinderopvang en het onderwijs, sociaal-cultureel werkers, artsen, verpleegkundigen, logopedisten, fysiotherapeuten en mensen die actief zijn in de sport- en vrijetijdssector.
