Published: May 2024

Determining the precise location of a ship navigating on a lake is of utmost importance for various logistical and safety reasons. However, this task can become particularly challenging when operating in regions with limited or no access to the Internet. Fortunately, advancements in technology, specifically the Internet of Things (IoT) utilizing Low Power Wide Area Network (LPWAN) technology, have offered a robust solution to address this issue. LPWAN technology enables long-range data transmission without being reliant on traditional internet connectivity.
In the context of our research, a LoRaWAN end node is employed equipped with LGT92, along with three gateways sourced from two different vendors, to effectively track the real-time position of a ship. To gauge the effectiveness of our system, let’s conduct experiments and obtained significant results. One noteworthy finding was that the communication range between one of the gateways and the LoRaWAN end node extended to 2.5 kilometers when utilizing the RAK 7243 gateway. In contrast, the Dragino LG308 gateway impressively stretched this range to 5.7 kilometers. All three gateways to broaden the tracking coverage area and ensure comprehensive monitoring are strategically deployed.
Our research's primary focus was tracking a ship's journey spanning 16 kilometers from Balige to Onanrunggu port. Throughout our experimentation, it is confirmed that the ship's precise coordinates, including latitude and longitude, were accurately transmitted from the end node on the ship to the designated gateway. This crucial position data was then seamlessly transmitted to the cloud. This real-time tracking capability proved invaluable, allowing for constant oversight and decision-making support during the ship's journey

Large communications of voice and images over the Internet, which leads to limited space for very large data during the aforementioned correspondence, to overcome this issue to maintain the quality of this technology.
The proposal in the efficient algorithm in this work is a method to derive the two new filters from the second and third Chebyshev polynomials by forming the discrete wavelets with the mother wavelet to be used in image processing in order to overcome the problem mentioned above due to the correspondence, The filters that were derived are Filter Discrete Second Chebyshev Wavelets Transform (FDSCWT) and Filter Discrete Third Chebyshev Wavelets Transform (FDTCWT)to process the image by analysis, noise reduction, and image compression.
Many of the techniques previously used in the field of image processing do not preserve image information during processing, but when using the new technology proposed in this work, it has been proven to preserve the image with its important information and data through the readings obtained shown in the tables below. These readings are average. Mean Square Error (MSE), Peak Signal Noise Ratio (PSNR), Bits Per Pixel (BPP), and Compression Ratio (CR) in preprocessing.
After the initial processing stage, the deep learning stage begins in the field of artificial intelligence. A (CNN) is trained with the two new filters to be the first Discrete Second Chebyshev Wavelets (DSCWCNN) and the second Discrete Third Chebyshev Wavelets Convolutional Neural Network (DTCWCNN), with the code being generated in the MATLAB program with a network Alex Net to complete the classification process that was added in this work to implement the recognition technology. Faces detection with new filters in deep learning to be a unique experience to reach a high level of accuracy of 98.60 % with the network for the filter DSCWCNN and 98.92 % with the network for the filter DTCWCNN in a very short time, which will be mentioned later in the work
Study on optimal water hammer protection for high-head and multi-undulation water conveyance system and empirical formulae for pressure head at nodes

Published: May 2024

ABSTRACT
The high-head and multi-undulation water conveyance system, which has a complex pipeline structure, can be prone to water hammer accidents. To prevent damage caused by pipe explosions and dents, measures must be taken to reduce both overpressure and negative pressure during water hammer incidents. This study simulated hydraulic transients using the characteristic curve method and also considered the possible water column separation effect. Parameter optimization and joint scheme selection were conducted for protective measures on the compound air valve group, one-way surge tank, and two-way surge tank. The research identified that the combined protective effect of the slow-closed check valve, compound air valve group, and one-way surge tank is optimal, with low cost and simple operation management. This can be considered the optimal scheme for water hammer protection in the high-head and multi-undulation water conveyance system. The study of the main control points of the pipeline revealed a slight correlation between the maximum relative head differences among nodes. Two empirical formulas, verified under 12 operating conditions, can connect the 9 main nodes with an average relative error mostly ranging from 1 to 5%. The reference significance of the empirical formula for this type of engineering can be verified.
Implications of the operation of continuous granular activated carbon filters on the effluent quality
Authors: Kirchen Franziska , Fundneider Thomas , Lackner Susanne 
Published: May 2024

ABSTRACT

Granular activated carbon (GAC) filtration is a commonly used method for advanced wastewater treatment. Filters can be operated continuously or discontinuously, with continuous operation not requiring feed flow interruption for backwashing and circulation (B/C). This study investigated the influence of B/C on the effluent quality of continuous filters. Two continuous GAC filters were operated for 1.5 years, with analysis of dissolved substances and particulate matter in the influent and effluent. The results indicated that various B/C modes had no impact on the removal of dissolved organic carbon and organic micropollutants (OMP), achieving an OMP removal of over 70% after 5,600 treated bed volumes (m3 treated wastewater per m3 GAC). However, it was evident that continuous B/C over 2–4 h resulted in increased turbidity, total suspended solids over 30 mg/L and total phosphorus concentrations of 1.3 mg/L in the filter effluent. Additionally, the study demonstrated that longer and more intensive B/C processes resulted in GAC size degradation with AC concentrations of up to 6.9 mg/L in the filter effluent, along with a change in GAC particle size. Furthermore, the importance of pre-filtration in reducing particulate matter in the filter influent and decreasing hydraulic head loss could be demonstrated.

Introduction:
A 9-aminoacridine derivative has anticancer properties against several
types of cancer cells, including colon, breast, pancreatic, lung, and renal cell carcinoma. It triggers
apoptosis by stopping the cell cycle in the S phase and inhibits the activity of topoisomerase.
So, the present study deals with the synthesis and anti-cancer activity of some of the acridine derivatives.

Methods:
The novel set of N-(acridin-9-yl)-N-(2-substituted benzoyl) derivatives were synthesized,
and these compounds were subjected to docking studies against topoisomerase II and the
result of docking studies revealed that all the compounds possessed promising activity against the
targeted enzyme. The docking studies revealed that the derivative AB7 showed a good docking
score of -8.7 kcal/mol when compared to doxorubicin.

Result:
The following derivatives AA2, AA3, AB3, AB7, AB7, AF6, AF10, AP7, AP10, and
APZ7 were selected for the synthesis by conventional method and further studies. These compounds
weresubjected to an in-vitro cytotoxicity study using the MTT assay method with MCF-7
cell lines. Among the tested compounds, derivative APZ7 substituted with chlorobenzene and
pyrrole ring showed a significant IC50 value (46.402 μg/ml), and the compound AP10 substituted
with chlorobenzene and pyridine moiety (59.42 μg/ml) exhibited promising inhibition in breast
cancer cell line.

Conclusion:
The current study suggests that the most effective anticancer compounds are found
in the substituted acridine derivative.

Background
Preoperative systemic inflammation and nutritional status have been shown to affect prognosis in patients undergoing transcatheter aortic valve implantation (TAVI). In this study, we investigated the effect of the Naples Prognostic Score (NPS), which consists of four different parameters including these two components on short- and long-term prognosis in patients undergoing TAVI.

Methods
In 343 patients (mean age 78.1 ± 8.4 years, 51.3% female) who underwent TAVI, the NPS score was calculated from the blood tests obtained before the procedure and the study population was divided into three according to the NPS value: those with 0 and 1 were divided into Group-1, those with 2 into Group-2, and those with 3 and 4 into Group-3. The relationship between NPS group and in-hospital adverse events and long-term survival was evaluated.

Results
Systolic pulmonary artery pressure, STS score, presence of chronic lung disease and being in NPS Group-3 [adjusted odds ratio (adjOR): 3.93, 95% confidence interval (CI) (1.02–15.17), P = 0.047] were found to be independent predictors of in-hospital mortality. According to the multivariate Cox-regression model, both Group-2 NPS [adjusted hazard ratio (adjHR): 4.81, 95% CI (1.09–21.14), P = 0.037] and Group-3 NPS [adjHR: 10.1, 95% CI (2.31–43.36), P = 0.002] was an independent predictor of 2-year all-cause mortality after TAVI. There was no significant difference in perioperative adverse events between the groups except for postprocedural acute kidney injury. According to receiver-operating characteristic analysis, the optimal predictive value of NPS for in-hospital and long-term mortality was 2.5.

Conclusion
In patients who will be candidates for TAVI, NPS is a simple and effective tool for determining both short- and long-term prognosis.

Published: May 2024

Abstract

Aims: To complete the syntaxonomic conspectus of the vegetation of Tajikistan, hot semi-deserts and ruderal vegetation, mainly of the lowlands and montane belt, were surveyed with some remarks on their environmental predictors. Location: Tajikistan.

Methods: A total of 143 relevés were sampled in 2022 using the seven degree cover-abundance scale of Braun-Blanquet. All these samples were classified by unsupervised k-means analysis with cut-offs of 0%, 5%, 25% and Hellinger transformation. Diagnostic species were identified using the phi coefficient as a measure of fidelity. Non-metric multidimentional scaling analysis was used to show the relationship between groups in the dataset with passively plotted environmental variables, to identify the influence of key environmental factors.

Results: Four new associations - Artemisio annuae-Dittrichietum graveolens, Eminio albertii-Haloxyletum persici, Leptalaeo filifolii-Calligonetum grisei and Clematidi songaricae-Ephedretum intermediae were coined. In addition, two vegetation types already known from Eastern Europe were found: Sagino procumbentis-Bryetum argentei and Amarantho blitoidis-Tribuletum terrestris. Three plant communities were additionally identified: Alhagi kirghizorum-Chrozophora tinctoria, Halimocnemis hispida-Microcephala lamellata and Salsola montana-Halogeton glomeratus. A new alliance (Carici physodes-Haloxylion persici) was proposed for the hot semi-desert shrublands of the Irano-Turanian region, and for the vegetation of large rocky outcrops, screes and badlands in the subhumid zone of Pamir-Alai, the alliance of Ephedro intermediae-Spiraeion baldschuanicae was proposed. The main factors responsible for the species composition of the studied vegetation are altitude, mean annual temperature and annual precipitation.

Conclusions: The dryland and ruderal vegetation of Tajikistan as in the whole arid Middle Asia is species rich and diverse, and deserves further detailed studies. Our research provides a first insight into this anthropogenic and natural vegetation of lowland, warm and often deserted areas, which are undergoing strong changes due to climate warming, grazing and urbanisation.
Extending Transceiver Capacity with a Scalable Spectrum Slicing Technique for Optical Access Networks

Published: May 2024

Abstract
The paper demonstrates a spectrum slicing technique applied to PAM-4 modulated signal spectrum at 40 Gbaud baudrate for optical access networks. The spectrum slicing is shown in VPIphotonics simulation environment, where characteristics of key components are measured in the laboratory and loaded into the corresponding elements of the simulation setup. The spectrum of electrical baseband signal is sliced in four slices introducing an additional degree of freedom – higher data rate signals can be transmitted by re-using already-existing lower bandwidth transceiver components in an optical access network. This tackles the electronic bottleneck enabling the on-demand variable bandwidth allocation and extends the life span of opto-electrical components during network upgrades. Furthermore, the use of the proposed spectrum slicing technique has a positive side-effect when it comes to security concerns, as the signal spectrum is divided into slices. All slices are necessary to obtain the reconstructed signal and even if an eavesdropper gets most of the slices it is still not enough. The simulation results show that the proposed spectrum slicing and stitching approach is a viable solution to overcome the problem of limited frequency bandwidth of electrical components.
Brought Through Senses: Exploring Senses as a Gateway to Memories in Gyasi’s Homegoing
Authors: Upreti Prateek , Semwal Sakshi 
Published: May 2024

Abstract
Autobiographical memory is a complex blend of memories of single, recurring, and extended events integrated into a coherent story of self, that is created and evaluated through sociocultural practices. These memories once integrated are recalled/retrieved through distinctive cues (different cues inducing different memories), both voluntarily and involuntarily. Yaa Gyasi is a young American novelist of African descent and her novel Homegoing (2016) is a story of history, colonialism, separation, migration, slavery, inter and intra-personal relations, and conflicts. Memory therefore is a dominant occurrence in Gyasi’s works. This paper analyses the use and allusion of five primary senses and their role as distinctive cues inducing distinct memories for the characters throughout the course of the novel. The study highlights how this usage helps Gyasi shape her characters and their characteristics connecting many small tales into one large narration. The paper also enquires how recalling and practicing other cues, mainly socio-cultural and religious, helps in forming and strengthening relations between similar groups of people in faraway lands through their shared collective memory.
The Image of the Ideal German Mother in Nazi Era Posters
Authors: Karatzas Konstantinos D. 
Published: May 2024

Abstract
This paper examines the role of women in Nazi Germany and ways the policy and propaganda implemented and enacted both plans an policies to transform women into the mothers of the nation. The paper will focus on the ways propaganda posters were used in order to engage public opinion, using the power of visual arts into manipulating public opinion that the body of a woman should be devoted to the Reich, (re-)producing the pure-blooded German and support the creation of a new empire. The posters supported and acted as a direct reminder of the policies set by Nazi regime, and their ideology on family planning, racial purity and gender roles. The propaganda machine that produced them borrowed symbols from religious works of the Renaissance connecting the “ideal mother” to images of Holy Mary, in a twisted connection between religion and social engineering. The presentation will discuss about the ways Nazi Germany elaborated the role of women, the (ab)use of their body and the ideal depiction of it according to the regime, the distortion of iconic renaissance paintings along with the ways that religion and public policy have been weaved in order to manipulate and re-educate an entire nation will be parts of the presentation in order to highlight this interesting part of history.
