Published: January 2025

WANET is a network built in an ad hoc network where various connecting devices and moving wireless nodes make connection with the exchange valuable information and wireless medium to one another. As the size of the wireless networks and internet architectures are increasing, there is an exponential demand for data processing and sharing resources in the WANETs. Most of the traditional node authentication models in WANET’s require high computational memory and resource constraints for data security and node authentication. In order to overcome these problems in the traditional models, a novel non-linear integrity-based intrusion detection models is designed and implemented in WANETs. In this work, a hybrid security protocol is designed and developed for the node-to-node communication system. In the proposed security protocol, a hybrid integrity approach and encryption framework is implemented on N2N communication process. Experimental results show that the present security protocol has better improvement on different metrics over traditional security approaches.

Authors: Gerdhem Lovisa , MacDowall Anna , Gerdhem Paul 
Published: January 2025

Background and purpose: Degenerative cervical myelopathy (DCM) is the most common cause of spinal cord dysfunction in adults. Repeated follow-ups after surgery are resource consuming. The aim was to examine whether patient-reported outcome measures (PROMs) change after the first year. The purpose of this study was to investigate whether it is necessary to obtain follow-up data from patients more than 1 year after surgery for DCM.Methods: We included individuals treated surgically for DCM in the Swedish Spine registry (Swespine), with available preoperative, 1-, and 2-year PROMs, primarily the European Myelopathy Scale (EMS) and secondarily the Neck Disability Index (NDI), and the European Quality of life Visual Analogue Scale (EQ-VAS). A tertiary analysis included available 5-year data. Median, interquartile range (IQR), and Bland–Altman plots were used to compare PROM data at different follow-up time points.Results: 642 individuals had baseline, 1-, and 2-year follow-up data, of whom 347 also had 5-year data. EMS was 14 (12–16) preoperative, 15 (12–17) at the 1-year follow-up, and 15 (12–17) at the 2-year follow-up. Corresponding data for NDI was 38 (24–50), 25 (12–42), and 26 (12–42) and for EQ-VAS 50 (30–60), 60 (42–77), and 60 (40–75). Similar findings were seen in individuals who also had 5-year data. Bland–Altman plots indicated good agreement between 1- and 2-year data, and between 1- and 5-year data and were without proportional bias.Conclusion: In individuals treated for DCM no clinically meaningful change in PROMs occurred after the 1-year follow-up.

Published: January 2025

Background and purpose: Recurrent hemarthrosis (RH) is a rare late complication of knee arthroplasty, with an unknown etiology. We aimed to evaluate the effectiveness of arterial embolization (AE) on resolution of hemarthrosis following knee arthroplasty. Additionally, we investigated pain management requirements after the procedure and related complications.Methods: 56 patients underwent AE for recurrent hemarthrosis between 2015 and 2023. The prevalence of hemarthrosis was 0.6%. The median age of the patients was 70 years (range 42–88), with 41 females and 15 males. 70 embolizations were performed, consisting of 56 initial procedures and 14 repeat procedures. Clinical success was defined as the resolution of hemarthroses.Results: Technical success was achieved in 93% of cases. Clinical success improved from 64% to 79% after the second treatment; subsequent sessions did not yield further improvement. 12 patients (21%) required 1 or more reoperations. The majority of patients (86%) relied solely on analgesics for post-treatment pain management. Complications occurred in 7% of treatments, most of which resolved spontaneously.Conclusion: AE is effective in the treatment of recurrent hemarthrosis but 21% had reoccurance. Oral analgesics are generally sufficient for managing post-embolization pain. 7% had complications.

The aims of this research were to determine the effect of temperature and duration of blanching to the characteristics of breadfruit flour and to test the level of consumer preference of cake made from breadfruit flour. Completely randomized factorial design with two factors: temperature (60°C, 70°C, 80°C) and duration of blanching (4 and 6 minutes) was conducted. The parameters measured are fineness modulus, grain size distribution, bulk density, color index and organoleptic score of cake made from breadfruit flour as a part or overall materials. The results showed that the temperature and blanching time affect the fineness modulus and of breadfruit flour granules. The higher the temperature, the longer the blanching time, and the smoother the fineness modulus, the finer the breadfruit flour granules. While, the lower the temperature and the duration of blanching, the color index of breadfruit flour is getting closer to white. The cakes made from 100% of breadfruit flour still have lower preference score compared with the cakes made from 100% of wheat flour in terms of taste, aroma, texture and color. Keywords: Blanching, Breadfruit, Flour.

This study aims to determine the effect of pressing duration and particle size on the pellet characteristics of sawdust. The study was conducted in a factorial completely randomized design using two factors. The first factor is the duration of the suppression which consists of four levels, namely 60, 120, 180, and 240 seconds. The second factor is particle size which consists of 40 mesh (fine), 30 mesh (medium), 20 mesh (coarse), and mixed. Sawdust is taken from a furniture industry in Bandar Lampung, then dried in the sun to a moisture content of about 12%, then sieved. Pellet molding was carried out with a mass of about 3 grams of material using a hydraulic press with a mold diameter of 12 mm. Sawdust is fed into the mould, then pressed by a hydraulic system at a pressure of 2 tons (172 Mpa). Parameters observed included density, moisture content, water absorption, pellet strength, pellet color, ash content and durability index. Each measurement was carried out with three replications. The results showed that the pressing duration and particle size affected the pellet characteristics. Biomass pellet made from sawdust had characteristics such as density of 0.813-0.856 g/cm3, moisture content of 8.19-12.15 %, maximum water absorption of 7.06-9.32 %, drop resistance of 99.41-99.66 %, and ash content of 1.087-2.082 %. Keywords: Density, Durability Index, Duration of Compression, Particle Size, Moisture Content.

The distribution of pigeon adenoviruses in Northern Chinese pigeon and turtledove flocks provides further evidence of viral crosstransmission
Authors: Li Yi , Xiang Chen , Xing Yanan , Jing Shengfan , He Hongxuan 
Published: January 2025

Abstract

OBJECTIVE
To understand the prevalence, genetic diversity, and potential pathogenicity of adenoviruses present in pigeon and turtledove populations.

METHODS
Nested PCR and Sanger sequencing methods were used to identify the genotype and percentage of various adenoviruses in the feces of pigeon (Columba) and turtledove (Streptopelia) populations. In Beijing, China, a total of 194 fresh feces samples from meat-use pigeons (C livia domestica), homing pigeons (C livia domestica), wild pigeons (C livia domestica), and turtledoves (S decaocto and S chinensis) were collected using noninvasive sampling collection techniques. Their partial DNA-dependent DNA polymerase gene sequences were obtained using nested PCR and double-ended Sanger sequencing, and their genotypes were then ascertained based on sequence alignment.

RESULTS
A total of 6 genotypes of adenovirus were detected in pigeon and turtledove flocks, including pigeon adenovirus (PiAdV)-1, PiAdV-2A, PiAdV-3, PiAdV-4, PiAdV-5, and a novel adenovirus genotype (PiAdV-6). Among them, PiAdV-1 was found widespread in flocks of pigeons exhibiting extensive presentations of hepatic necrosis. Highly conserved PiAdV-4 and PiAdV-5 were found to be nonpathogenic and extensively distributed in all pigeon and turtledove groups.

CONCLUSIONS
These findings imply the presence of diverse PiAdVs in pigeon and turtledove flocks, and the wild pigeons and wild turtledove birds are potentially serving as natural sources of these viruses.

CLINICAL RELEVANCE
This study provides supportive evidence of the pathogenicity of different genotypes of adenovirus in pigeon flocks and also implies that stopping the transmission of the virus brought by wild pigeons and turtledoves may be important for the prevention of diseases associated with PiAdVs.

Published: January 2025

Abstract

Objective
To determine the predictive potential of the open reading frame 5 nucleotide sequence of porcine reproductive and respiratory syndrome (PRRS) virus and the basic demographic data on the severity of the impact on selected production parameters during clinical PRRS outbreaks in Ontario sow herds.

Methods
A retrospective longitudinal study of clinical outbreaks in Ontario sow herds at various points between September 5, 2009, and February 5, 2019, was conducted using herds as units of analysis. Data were gathered from study sow farms in Ontario at the start of each clinical outbreak. Six machine learning models and 2 different genetic input structures of open reading frame 5 sequences were utilized to predict the impact on abortion and preweaning mortality.

Results
Extreme boosting machine learning models with genetic data represented through 2-dimensional multiple correspondence analysis had the highest accuracy when predicting clinical outcomes (60.8% [SD = 12.4%] and 74.4% [SD = 13.2%]) for abortion and preweaning mortality outcomes, respectively. The mean sensitivity of classifying outbreaks with a high impact on abortion was 50%, with a specificity of 89.2%. The mean sensitivity of classifying outbreaks with high preweaning mortality was 56.2%, with a specificity of 85.2%.

Conclusions
The data and methods utilized herein exhibited improvement in accuracy over the baseline; however, this increase was not sufficient to warrant field implementation.

Clinical Relevance
Predictive models based on observed data could assist practitioners in linking the genetics of the PRRS virus with clinical impact in clinical settings. Models trained in this study show promise for PRRS clinical impact prediction.
University Management Practice: A Restorative Approach to the Dwindling Quality of University Education in Developing Countries
Authors: Ohanyelu Charles N. 
Published: January 2025

Abstract
The study investigates how university management practices could be applied as a novel and restorative strategy to improve the declining quality of university education in developing countries. A survey questionnaire was employed as a research tool in February-December 2022, and participants (n = 505) were selected from the total population, which comprised both management, administrative, and academic/non-academic staff of the selected universities from among the six geopolitical zones in Nigeria, using a simple random technique. The study applied Spearman’s rank-order correlation coefficient and Kruskal-Wallis tests for statistical hypothesis testing. Based on Spearman’s rank-order correlation coefficient results, hypothesis H1 was rejected, and a favorable, moderate, and statistically significant relationship between students’ academic performance and university management practice has been confirmed. At the same time, hypothesis H2 was confirmed using the Kruskal-Wallis test, and there is no statistically significant difference between students’ academic performance and the university’s geopolitical location. The study concludes that an efficient democratic management practice positively affects the overall quality output of university education. The study is unique because the principles of the University Education Quality Improvement Model (UEQI model) were applied to improve the status quo.

Authors: Murgia André 
Published: January 2025

Abstract
This article aims to discuss the issue of political agency in the context of the climate crisis. In this regard, the article reports and analyzes the outlines of the debate on the relationship between human beings and the non-human world, and takes Bruno Latour’s theoretical proposal and some criticisms of it as a reference. For the most part, this debate revolves around ontological questions concerning the status of human beings in the world. Such questions provide arguments for better understanding whether politics represents an autonomous dimension in which human agency possesses a peculiar meaning or not.
