Authors: Saeed Awais , Khan Adnan Ahmed , Shah Syed Ismail , Yasin Shariq
Published: December 2022

To launch a cellular network, prelaunch capacity dimensioning is performed which includes coverage estimation and throughput prediction. Cellular companies in developing countries like Pakistan are only providing 2G services, while 3G services are yet to be launched. Although a lot of research has been done on 3G services in developed countries but there is very little knowledge regarding practical aspects of planning and optimization of 3G networks in third world countries like Pakistan. This research paper includes a thorough analysis of factors that affect capacity of 3G networks, including radio propagation models. Various propagation models are studied and propagation constants of Standard Propagation Model are tuned according to topography of Islamabad. The performance analysis of these propagation models is done using Matlab and results are verified through planning tool Atoll and field measurements. Based on analysis of these results capacity dimensioning, in terms of number of sites, is carried out for an urban network of Islamabad.

Published: December 2022

Multi-carrier cooperative relay-based wireless communication is of particular interest in future wireless networks. In this paper we present resource allocation algorithm in which sub-carrier pairing is of particular interest along with fairness constraint in multi-user networks. An optimization of sub-carrier pair selection is formulated through capacity maximization problem. Sub-carrier pairing is applied in both two-hop Amplify & Forward (AF) and Decode & Forward (DF) cooperative multi-user networks. We develop a less complex centralized scheme for joint Sub-carrier pairing and allocation along with relay selection. The computational complexity of the proposed algorithms has been analyzed and performance is compared with Exhaustive Search Algorithm.

Emigracyjna działalność ks. Szczepana Walkowskiego – kapłana diecezji częstochowskiej (1912-1969)
Authors: Kęsik Kamil
Published: December 2022

Szczepan Walkowski urodził się 12 listopada 1912 r. w Wieruszowie. Po wstąpieniu do seminarium duchownego w Krakowie w 1934 r. odbył studia filozoficzno-teologiczne i angażował się w organizacje studenckie. Święcenia kapłańskie przyjął w czerwcu 1939 r. Niebawem został wikariuszem w Lututowie. Już 2 września musiał stamtąd uciekać z powodu wybuchu II wojny światowej. Przechodząc przez Jugosławię i Rumunię dotarł do Rzymu. Niebawem przeniósł się do Francji do Coetquidain na pierwszy turnus szkoły podchorążych. Został kapelanem Brygady Podhalańskiej, następnie Zapasowego Ośrodka Oficerskiego w Sables-d’Or-les Pains. Po zdobyciu Francji prze Hitlera w czerwcu 1940 r., przeniósł się do Anglii gdzie niebawem został przydzielony do lotnictwa polskiego w ramach RAF-u. Po wojnie został uznany przez wadze sowieckie w Polsce za wroga narodu, dlatego w 1949 r. emigrował do Argentyny. Rozpoczął szeroką pracę duszpastersko-oświatową w Quilmes w prowincji La Plata. Zginął w wypadku samochodowym 8 czerwca 1969 r. Powyższe fakty udało się ustalić na podstawie dostępnych archiwaliów, w zdecydowanej większości wykorzystanych po raz pierwszy do pracy naukowej. Dzięki nim ukazano przebieg pracy kapłańskiej w rzeczywistości emigracyjnej, ze szczególnym uwzględnieniem okresu II wojny światowej i pobytu w Argentynie. Panoramiczne spojrzenie na aktywność duszpasterską ks. Walkowskiego ukazuje postać polskiego patrioty budzącego wzniosłe uczucia wśród Polonii. Śledząc kolejne homilie duchownego poruszające temat wojny i powojennego komunizmu w Polsce, zauważa się jego zatroskanie o pomyślny rozwój ojczyzny. Mając świadomość, że nie będzie mógl wrocić do Polski, podejmował działania mające na celu podnoszenie morali rodaków na obczyźnie, którzy mieli być przykładem religijności i miłości do rodzinnych stron.
The Mpox, serious menace, or paper tiger?
Authors: Jalilian Shahram , Bastani Mohammad-Navid
Published: December 2022

One of the most horrible diseases in history, Smallpox is caused by the Variola from Poxvirus family, has caused great mor- bidity and mortality along the waysince it was eradicated in the 20th  century. During and after the eradication program for Variola, other Poxviruses such as the Monkeypox (Mpox) virus, whichcauses a smallpox-like disease, became flagrant. With its long range of enzymes and proteins, poxviruses are effectively resisting hostile immune systemattacks and disrupting cell signaling pathways. After Smallpox vaccination, cross-reaction immunity develops between Orthopoxviruses. Mpox is indeed an African endemic virus; however, increasing and emerging cases have been reported globally in recent years. According to Smallpox eradication in the 1970sand vaccination ceasing, nowadays centerpieces of the world population are vulnerable to Mpox virus. Our knowledge of Mpox is severely limited due to the lack of regular surveillance methods. Increasing education, boosting surveillance, and developing diagnostic competence is the most significant policies forim- proving identification, treatment, and restricting further virus spread. So Mpox can play a double-edge blade role in which without monitoring andincreasing awareness it could be horrific and with public awareness and boosting surveillance it could be a paper tiger. This article reviewed previous reportsabout the Mpox merge from PubMed and google scholar from 2018 to June 2022.

Published: December 2022

The ongoing 2022 multicountry monkeypox epidemic has drawn worldwide attention. Human monkeypox is a virus that spreads from animals to humans. It isan endemic disease in the rain forests of Central and West Africa. However, the disease recently emerged in India, and also in United States through importedwild rodents from Africa, even though the world is still struggling to escape from the clutches of the COVID-19 pandemic. Monkeypox is one of thecontagious zoonotic dis- eases caused by the monkeypox virus (MPXV), transmitted to humans by direct contact with an infected person or animal or contact with virus-contaminated material. Its lesions are similar to smallpox in humans with various medical complications including flu-like symptoms, fever, malaise, back pain, headache, and a characteristic rash. Public health experts around the world are very concerned about the rapid spread of the infection, which hasintensified efforts to find the source and cause of this phenomenon. Several viral infections with epidemic potential threaten global health security. Early recognition of cases and timely intervention of potential transmission chains are necessary to contain further outbreaks. At this early stage of monkeypox outbreaks, the current review provides updated information on the current worldwide monkeypox outbreak status, disease aetiology, clinical presentation,therapy, and preventive measures worldwide. Our review will also provide useful information to health professionals and the general public.

Erken çocukluk döneminde özel eğitim, gelişimsel olarak risk altında olan veya yetersizliğe sahip 0-8 yaş çocukların gelişimlerini desteklemeyi, akranlarıyla aralarındaki gelişimsel farklılıkları en aza indirmeyi ve bu dönemde ailelerin ihtiyaçlarına cevap vermeyi hedefleyen eğitim hizmetleridir. Bu araştırmanın amacı 0-36 ay arası tanılanan özel eğitim ihtiyacı olan çocuklara hizmet sunan eğitmenlerin erken müdahale (EM)/erken çocukluk özel eğitimi (EÇÖE) programlarına ilişkin görüşlerinin neler olduğunu incelemektir. Bu amaçla araştırma nitel araştırma yöntemlerinden fenomenoloji deseni ile tasarlanmıştır. Buna göre araştırmaya özel eğitim ve rehabilitasyon merkezlerinde görevli on sekiz eğitmen katılmıştır. Araştırma verileri yarı yapılandırılmış görüşme soruları sorularak yüz yüze ve telefon görüşmeleri ile toplanmıştır. Toplanan veriler Moustakas’ın (1994) fenomenoloji deseni için önerdiği analiz yaklaşımının adımları izlenerek analiz edilmiştir. Bu araştırmada 0-36 ay arasında özel eğitim ihtiyacı olan çocuklar ile çalışan eğitmenlerin çoğunun herhangi bir EM/EÇÖE programından faydalanmadıkları belirlenmiştir. Benzer şekilde, katılımcıların çoğunun herhangi bir EM/EÇÖE programından yararlanmayı planlamadığı sonucuna varılmıştır. Diğer çarpıcı sonuç ise katılımcıların Milli Eğitim Bakanlığı 0-36 Ay EÇÖE Programı hakkında farkındalıklarının olmadığı anlaşılmıştır. EM/EÇÖE programlarından beklentilerin ise iletişim becerilerini başta olmak üzere tüm gelişim alanlarını desteklemeye yönelik, aile katılımını esas alan, değerlendirme ve etkinlik temelli olması şeklinde olduğu belirlenmiştir.

TRESMINAS
Authors: Wahl-Clerici Regula
Published: December 2022

Das römische Reich benötigte für seine Truppen jährlich 400 bis 500 Millionen Sesterzen, wobei der grösste Teil dieser Summe aus logistischen Gründen in Form von Gold und Silbermünzen zur Verfügung stehen musste. Natürlich mussten dieses Gold und Silber nicht alljährlich zusätzlich gefördert werden. Die Höhe der neu zu gewinnenden Menge, war unter anderem vom Rücklauf durch die Steuereinnahmen, durch die Zölle sowie von der Veränderung der Truppenstärke, von Solderhöhungen und von kaiserlichen Geschenken an die Truppen (donativa) und an die Bevölkerung (congiaria) abhängig. Beispielhaft zeigen sich diese Gemeinsamkeiten am territorium metallorum Tresminas/Jales und dem Legionslager von Carnuntum, auch wenn sie fast 3000 km auseinanderliegen und keine direkten Beziehungen nachzuweisen sind. Die reichen Denkmälerbestände des vom 1. bis gegen Ende des 4. Jahrhunderts benutzten Legionslagers an der Donau in der Provinz Pannonien, neben dem sich eine Stadt entwickelte und auch ein Hilfstruppenlager sowie ein Lager der Gardetruppen des Provinzstatthalters entstanden, und des Bergwerksdistrikts von Tresminas, in dem zumindest im 1. und im 2. Jahrhundert n. Chr. Gold gefördert wurde, machen die beiden zu hervorragenden Beispielen ihres Typs. Deshalb kann sich der Besucher an beiden Orten ein Bild der wichtigsten Stützen des römischen Reiches machen: Geld und Militär. Wir freuen uns deshalb, dass in diesem Buch die Erstpublikation des Aufsatzes «Das territorium metallorum Tresminas/Jales» in den Acta Carnuntina 8/2/2018 in den Sprachen Deutsch, Portugiesisch und Englisch einem grösseren Publikumskreis zugänglich gemacht werden kann. Ergänzend werden Informationen zum Besuch der beiden Kulturdenkmäler angefügt.

Published: December 2022

Corruption is a phenomenon not easy to observe. Corruption theory and existing definitions are ambivalent, both in size and level. Mathematical models, and  econometrics are prone to statistical errors. Fuzzy logic facilitates more humane modeling and analysis. Fuzzy logic is not bound by strong assumptions, as a solution to solve complex problems, and not precise, including corruption analysis. The main objective of this study is to measure corruption in Indonesia. The research method used fuzzy logic by specifying the Mamdani fuzzy inference system (FIS) model. FIS Mamdani was chosen because it is more human manner. Sources of secondary data used in this research from various institutions. The results show that corruption time series data can be produced. During the research year (1995-2020), corruption that occurred in Indonesia was 36.14 percent of real GDP per capita.

Published: December 2022

This study examines FDI influence on economic growth in 24 emerging market economies. The generalized Method of Moment (GMM) method is used in this research using panel data to see the effect of FDI on economic growth. This study also uses the Panel Vector Error Correction Model (PVECM) method to see the short-term relationship and Fully Modified Ordinary Least Square (FMOLS) to see the long-term relationship. This study finds strong empirical evidence indicating that the influence of FDI on economic growth is statistically significant in the short and long term. These results vary if we include the level of development reached by countries in emerging market economies. In upper-middle and lower-middle-income countries, FDI positively and greatly influences economic growth. Different results occur in high-income countries, and the results are positive and insignificant. The results show that FDI in high-income countries tends to leave these countries.

Authors: Dewanti Larasayu Anindya , Rusmita Sylva Alif , Samad Khairunnisa Abd
Published: December 2022

The current study focuses on the existence of exchange rate volatility that impacts the return of MSCI Islamic stocks in Asia emerging countries. The study also sees comparisons between Islamic emerging markets in Asia (India, China, and Korea) and Southeast Asia regions (Indonesia, Malaysia, Thailand, and the Philippines). This study's daily time series data is from January 2015 to June 2020, employing time series regression as an analysis technique. The EGARCH method is used to indicate the asymmetric model and examines the impact of both good and bad shocks generated. The results highlight that the volatility of the MSINI is statistically positive, whereas MSCNI and MSKRI show a significant adverse effect on volatility. On the other hand, Southeast Asia (MSIDI, MSMYI, MSTHI, and MSPH) has no significant effect on exchange volatility. It is interpreted that the currencies of Southeast Asian countries are not strong enough because they still depend on other exchange rates. This result can be utilized to invest in the Islamic stock market in Southeast Asia because it is not affected by exchange rate volatility. Investors can quickly react to sensitive stocks to avoid uncertainty in stock returns. The government must be advised to increase the fiscal stimulus space and provide ease of business in the real sector.

Research on the occurrence and the characteristics of microplastics (MPs) sedimentary in seagrass meadows at the area of Mare Island conservation is the very first study in this region. The objectives of this work is to determine the abundance and the characteristics of MPS and its diversity in the two villages namely Maregam and Marekofo at the Island. Samples are collected using sediment core, then dried and extracted using NaCl to separate the density. MPs were identified under a microscope after going through the filtering process. The abundance of MPs particles ranges from 17,000 - 37,000 particles. kg-1dry weight (dw) sediment at Station 1 (Maregam) and 13.839 - 30,666 particles.kg-1 dw sediment at Station 2 (Marekofo). In general, the average value of MPs abundance at station 1 higher than station 2 were 27.090 Â± 13.908 particles.kg-1 dw of sediment and 18,368 Â± 10,625 particles.kg-1 dw of sediment, respectively. Statistically there no significance difference of the MPs abundance between the two station Furthermore, the predominance of MPs types were fiber and fragments, while the majority of colors of particles were blue. While the results of the microplastic diversity test indicated that MPS particles at Mare Island were not too complex and were in unstable conditions. Even though the less density of the population at the island, MPs were quite high compared to other areas in the world. This finding is allegedly that those MPs were supplied from the distance which transmitted by hydro-oceanographic and meteorology factors, beyond of local contribution.Keywords: Microplastic, seagrass bed, sediment, conservation area, Mare Island

The purpose of this study is to see how effective the use of different vegetable plants in an aquaponic ebb-tide system for intensive culture. As much as 3000 catfish (Clarias sp.) were stocked per pond (measuring 4 x 2 m2), with individual lengths of 8-10 cm. A completely randomized design (CRD) with three treatments and three replications was used in this study. With 60 days of observation, the research treatments included a variety of vegetable plants: (A) water spinach, (B) caisin, and (C) no plants (control). Absolute weight gain and survival rate, water physico-chemistry parameters, Total N and Total P analyses on vegetable plants among the observation parameters. Treatment was found to have the highest average weight gain and survival rate (73.63 g and 87.41%, respectively). Water spinach biomass was 102 kg at the end of the study, whereas caisin biomass was 72.54 kg. Total N and Total P absorption percentages in water spinach were 38.72% and 54.43%, respectively, while 36.00% and 49.55% in caisin. The catfish condition factor showed correlation coefficients with fish weight R2 = 0.978, R2 = 0.956, and R2 = 0.357 and R2 = 0.892, R2 = 0.8215 and R2 = 0.369 for length in the water spinach, caisin, and control treatments, respectively. This study's analysis of water quality parameters indicated that the A treatment had the lowest levels of ammonia, nitrite, and nitrate when compared to the B and C treatments.Keywords: catfish, aquaponic ebb-tide, water spinach, caisin

Published: December 2022

The COVID-19 pandemic has impacted the seaweed industry and business. The export-import trade is the most severely impacted sector, mainly the raw material export of seaweed. The purpose of this study was to determine how smallholder farmers in West Nusa Tenggara, Indonesia, can survive under adverse conditions and maintain their businesses during a pandemic. The research was conducted through a combination of field surveys and in-depth interviews with respondents. Interviews were performed using a variety of instruments, including questionnaires and cameras. According to the study's findings, smallholder farmers are impacted by a decline in prices and demand. Smallholder farmers in West Nusa Tenggara, Indonesia, are attempting to adapt or adjust their operations to maintain profitability. Seaweed farmers make significant savings and cut their spending in the event of a pandemic. What is intriguing is that respondents did not reduce their spending on food. Instead, they prioritize reducing tertiary needs. Additionally, the same holder farmer borrows from collectors, borrows from the bank, and works side jobs. Thus, seaweed farmers are relatively unaffected by this pandemic and recover more quickly than other types of fishery businesses.Keywords: Covid 19, seaweed, smallholder farmer, Nusa Tenggara Barat

Authors: Gísladóttir Thordis , Petrovic Milos
Published: December 2022

Basketball is a highly anaerobic game, that consists of high-intensity efforts followed by lower-intensity efforts. Postural deformities can be a limiting factor in achieving maximal performances in basketball. Flat feet are one of the most common deformities and they can lead to poorer performances, discomfort and pain. In this research we made an attempt to link the degree of feet flatness with sports performances among Icelandic adolescent basketball players. A sample of 100 basketball players was tested on a podoscope to establish the degree of feet flatness and all participants performed countermovement jump, 20m sprint and pushups in 30 seconds. No significant correlation was observed between feet status and sports performances. No differences were found between groups with and without flat feet, which indicates that feet flatness was not a limiting factor in achieving better results. However, we state that only strong and healthy feet might lead to excellent performance.

Gastro-retentive floating microspheres were developed as a result of the recent advancements in floating delivery systems for drugs (FDDS), which included the uniform dispersion of multiparticulate dosage forms along the GIT. This could lead to more consistent drug absorption and a lower risk of local irritation. Microballoons (MB), a multi-unit extended release with a sphere-shaped cavity encased in a tough polymer shell, have been developed as a dosage form with exceptional buoyancy in the stomach. This preparation for constrained intestinal absorption is made to float on top of gastric acid, that has a relative density lower than 1.By using enteric acrylic polymers and the emulsion solvent diffusion method, microballoons are prepared and filled to drug in one‘s outer polymer casings. Enteric acrylic plastics are used to generate microballoons that are drug-loaded in one‘s external polymer casings and dissipate in a solution of dichloromethane and ethanol. Cavity development in microparticles seems to be particularly correlated with dichloromethane evaporation. Microballoons with a drug distributed or dispersed all through the particle-matrix have the potential for a controlled drug release and float continuously for more than 12 hours in vitro out over the surface of an acidified dissolution medium with surfactant. The drug is released slowly and at the desired rate as the microballoons glide over the components of the stomach, increasing gastro-retention time and lowering fluctuations in plasma concentration.

In spite of large-scale investigations of homogeneous single-site metallocene catalysts and systems based on them, the problem of controlling their activity, chemo- and stereoselectivity with the aim of developing efficient methods for the preparation of practically useful products of alkenes transformation, such as dimers, oligomers, and polymers, still remains topical. Here we studied catalytic activity of differently structured zirconocenes (10 examples of cyclopentadienyl and indenyl complexes) and co-catalysts activating the system, namely HAlBui2, MMAO-12 or (Ph3C)[B(C6F5)4] at low activator/Zr ratios in 1-hexene oligomerization reaction. The influence of catalyst structure and system composition on alkene conversion, type of products formed and reaction stereoselectivity was investigated. The composition of hydride intermediates forming in the systems L2ZrCl2 (L2= ansa-Me2CCp2)-HAlBui2-activator was studied by NMR and the participation of biszirconium hydride complex as the precursor of catalytically active sites of the alkene dimerization reaction was shown.

Published: December 2022

Fan coils are widely used in heating and air conditioning systems in both residential buildings and commercial areas. This article deals with the creation of a mathematical model of the fan coil for use in control systems, building digital twins, etc. The development of models of components of building engineering systems contributes to the introduction of more sophisticated control algorithms and analytics to coordinate the operation of equipment and as a result improve the energy efficiency of systems, the ability to investigate the dynamics of systems, etc. In this paper, a system of heat balance equations for the water, air and walls of the heat exchanger was used, which allows for simulating the operation of the system in transient modes. Considerable attention was paid to the calculation of the coolant and air parameters, including specific heat capacity, heat transfer coefficients, water and air thermal conductivity, kinematic viscosity coefficients, density, etc. The use of dynamic calculation of the coolant and air characteristics was proposed, an algorithm using the Python programming language and the CoolProp, SciPy, and NumPy libraries were implemented, and simulation results were presented. To assess the effectiveness of the proposed solutions, an analysis of the simulation results for the system with constant values of the coolant and air parameters, determined from the averaged initial values of the input and output parameters of the model, compared to the system with dynamic calculation, was performed. Finally, we investigated the dynamics of the external factor influence on the simulation results and presented an analysis of the influence of the model input variables on the output temperature values due to implicit relationships in the calculation of the parameters characterizing the heat transfer fluid and the air in the fan coil. According to the results of the comparison, the deviations in the simulation results of the models under study were estimated for the calculated value of heat output on the air side in absolute and relative units.

Published: December 2022

The specific features of UAV like energy efficiency, dynamic structure and mobility in Flying Ad-hoc Network (FANET) is good utilized for the selection of UAV in a vast variety of applications like disaster management, rescue management, medical, and military. So, the effectiveness of FANET is reduced by enhancing the packet transmission expenses due uncreative and indecisive communication among UAVs in multidimensional environment. The optimal path selection will support to proficient message transmission and offer energy competent and protected communication above FANET. Thus, an Improved Honey Badger Optimization based Communication Approach (IHBO_CA) is implemented for optimal path selection among UAVs above FANET. The sinusoidal chaotic map is combined with honey badger algorithm to improve the performance of optimized communication. The IHBO_CA is implemented using MATLAB 2021a platform and outcomes demonstrate the greater effectiveness of IHBO_CA against OLSR, MP-OLSR, ACO, PSO and HBA depending on energy expenditure, overhead, time complexity, packet delivery ratio and delay.

Published: December 2022

Water meter measurement error is considered as one important component of non-revenue water (NRW) by International Water Association (IWA). Its magnitude depends combinedly on users’ consumption behaviors (intake spectrum) and metrological characteristics of water meters (meter error curve). Most published researches have only analyzed the meter error curves without taking the users’ consumption behaviors into consideration. This study developed a practical approach by using the relative error chart of master-meters and sub-meters groupings (i.e., RM-chart) to identify average metering errors for a major water utility company in Taiwan. About 120,000 sets of “master-meter and sub-meter grouping” data of Taipei Water Department (TWD) were analyzed. The approach successfully estimated average metering errors of its 99.6% domestic meters (around 1.58 million water meters), the results are 9.85%, 6.11%, and 10% less than the actual water consumption recorded by the sub-meters, master-meters, and direct-meters, respectively.

Schizophrenia is a neuropsychiatric disorder, caused by a combination of genetic and environmental factors. Recently, metabolomic studies based on patients’ biofluids and post-mortem brain specimens have revealed altered levels of distinct metabolites between healthy individuals and patients with schizophrenia (SCZ). However, a putative link between dysregulated metabolites and distorted neurodevelopment has not been assessed and access to patients’ material is restricted. In this study, we aimed to investigate a presumed correlation between transcriptomics and metabolomics in a SCZ model using patient-derived induced pluripotent stem cells (iPSCs). iPSCs were differentiated towards cortical neurons and samples were collected longitudinally at defined developmental stages, such as neuroepithelium, radial glia, young and mature neurons. Samples were subsequently analyzed by bulk RNA-sequencing and targeted metabolomics. The transcriptomic analysis revealed dysregulations in several extracellular matrix-related genes in the SCZ samples observed in early neurogenesis, including members of the collagen superfamily. At the metabolic level, several lipid and amino acid discrepancies were correlated to the SCZ phenotype. By employing a novel in silico analysis, we correlated the transcriptome with the metabolome through the generation of integrative networks. The network comparison between SCZ and healthy controls revealed a number of consistently affected pathways in SCZ, related to early stages of cortical development, indicating abnormalities in membrane composition, lipid homeostasis and amino acid imbalances. Ultimately, our study suggests a novel approach of correlating in vitro metabolic and transcriptomic data obtained from a patient-derived iPSC model. This type of analysis will offer novel insights in cellular and genetic mechanisms underlying the pathogenesis of complex neuropsychiatric disorders, such as schizophrenia.

In this article, we present the synthesis ofPiper longumleaves-derived ethanolic carbon dots (PLECDs) using the most simplistic environmentally friendly solvothermal carbonization method. The PLECDs fluoresced pink color with maximum emission at 670 nm at 397 nm excitation. Additionally, the dried PLECDs dissolved in water showed green fluorescence with higher emission at 452 nm at 370 nm excitation. The UV spectra showed peaks in the UV region (271.25 nm & 320.79 nm) and a noticeable tail in the visible region, signifying the efficient synthesis of nano-sized carbon particles and the Mie scattering effect. Various functional groups (-OH, -N-H, -C-H, -C = C, -C-N, and -C-O) were identified using Fourier-transform infrared spectroscopy (FTIR). Its nanocrystalline property was revealed by the sharp peaks in the X-ray diffraction (XRD). High-Resolution Transmission Electron Microscopy (HRTEM) photomicrograph displayed a roughly-spherical structure with a mean size of 2.835 nm. The Energy Dispersive X-ray (EDAX) spectra showed the presence of C, O, N, S, and P. The High-performance thin layer chromatography (HPTLC) fingerprint of PLECDs showed an altered pattern than its precursor (Piper longumleaves ethanolic extract or PLLEE). The PLECDs sensed Cu2+selectively with a limit of detection (LOD) of 0.11 µM. It showed excellent cytotoxicity towards MDA-MB-231 (human breast cancer), SiHa (human cervical carcinoma), and B16F10 (murine melanoma) cell lines with excellentin-vitrobioimaging outcomes. It also has free radical scavenging activity. The PLECDs also showed outstanding bacterial biocompatibility, pH-dependent fluorescence stability, photostability, physicochemical stability, and thermal stability.
