Behavior of thin-walled tubes with combined cross-sectional geometries under oblique loading

Hollow tubes are the most important part of any structure because of their load-bearing capacity, lightweight and inexpensive manufacturing cost. One of the methods for improving the performance under quasi-static loading is to vary the cross-sectional shapes. In the real case, structures are seldom subjected to pure axial or pure bending rather they are subjected to a combination of two load cases i.e. oblique loading. In this paper, the circular cross-section was combined with four different polygonal cross-sections namely tetragon, hexagon, octagon and decagon and a total of 13 geometries were obtained. The buckling behavior of each tube was investigated numerically at various angles of inclination. Each tube was modeled in SOLIDWORKS and then was analyzed in ANSYS. Linear buckling code was used for finding the critical load at various angles ranging from 0° to 14°. The overall result was then compared and it was found that the proposed geometry can be a good alternative over conventional circular tubes in terms of load-bearing capacity at angular load

Review of Erbium-doped fiber amplifier

Data communication systems are increasingly employing optical fiber communication systems (OFCS) as the transmission paths for information. Various types of optical amplifiers have been developed in OFCS to amplify optical signals. In particular, the Erbium-doped fiber amplifier (EDFA) is one example of an optical fiber amplifier that is widely known for use in amplifying optical signals. The most significant points in any optical amplifier design are gain and noise figure (NF). They are closely related to each other. Low NF and high gain are the main features for optimum amplifier (Desurvire, 1987). On the other hand, the gain and NF have very strong impact with EDFA’s configurations. Therefore, changes in EDFA’s configuration play very important role during the designing of optical amplifier. The literature shows that there is no study that has been done to review the EDF configuration. Therefore, in this paper we are presenting an overview of most of the EDFA’s configurations that have been proposed in order to provide the researchers with a clear view of what has been done in this field

Green pharma supply chain: a review of existing practices and future directions

Purpose The pharmaceutical industry is facing significant pressure to tackle antimicrobial resistance (AMR). Other ecological, societal and regulatory pressures are also driving the industry to “go green”. While such a (green) transition could be possible through appropriate green practices’ implementation, the present understanding about it is superficial and vague. A key reason is the lack of green practices’-related studies on pharmaceuticals, which are also insufficiently comprehensive. This knowledge gap is sought to be addressed. Design/methodology/approach A systematic literature review (SLR) was conducted with 73 carefully selected articles, then subjected to thematic content analyses for synthesising the relevant themes and sub-themes. Findings Around 76 operational-level green practices covering all key stakeholders across the drug lifecycle were identified. It was revealed that designing drugs having accelerated environmental degradability is important to combat AMR. Also, redesigning existing drugs is environmentally more resource-intensive than developing new ones with significant cost-saving potential in solvent recycling and flexible manufacturing, both of which are not common at present. With regards to green-related barriers, stringent quality requirements on drugs (and therefore risks in making relevant green-oriented modifications) and time-consuming and costly regulatory approvals were found to be the key ones. Practical implications The operational green practices’ framework developed for individual pharmaceutical supply chain stakeholders could help practitioners in benchmarking, modifying and ultimately, adopting green practices. The findings could also assist policymakers in reframing existing regulations, such as Good Manufacturing Practices or GMP-related, to promote greener drug development. Originality/value This work is the first systematic attempt to identify and categorise operational-level green supply chain practices across stakeholders in the pharmaceutical sector. Highlights • Biodegradability of drugs is more important than environmental degradability. • Flexible manufacturing process design (or quality by design) reduces resource wastage. • Ecopharmacovigilance is effective in combating PIE and AMR-related issues. • Upstream and downstream coordination is key to greening pharma operations. • Costly and time-consuming regulatory approval is a key barrier to greening pharma processes

A comprehensive review on the impact of cervical spondylosis on quality of life and its management through Unani system of medicine: a review

In the Unani system of medicine, cervical spondylosis is categorized under the broad term known as Waja-ul-Mafasil, which encompasses a wide range of joint disorders including inflammatory, non-inflammatory, infectious, metabolic, and other musculoskeletal ailments. Cervical spondylosis specifically refers to the degenerative changes in the intervertebral discs and adjacent vertebrae in the cervical spine, primarily caused by age related wear and tear. Given the limitations and side effects associated with long term conventional treatments and the considerable impact of the condition on an individual’s physical, mental, and social wellbeing many patients explore alternative therapies. Unani medicine offers various treatment strategies, known as Tadabeer, for managing joint related conditions. This literature review aims to evaluate the existing evidence provided by classical Unani scholars and assess clinical studies on the effectiveness of different regimenal therapies in alleviating joint pain through Unani approaches. The review was conducted using databases such as Google Scholar, PubMed, Science Direct, and Medline, along with classical Unani manuscripts accessed from the library of State Unani Medical College, Prayagraj, Uttar Pradesh, India. Considering the inadequacy of conventional medical treatments, Unani medicine presents a promising alternative through its comprehensive methods including dietary regulations, regimenal procedures, and pharmacological interventions for managing cervical spondylosis.

Molecular characterization, cloning and sequencing of coat protein gene of a Pakistani potato leaf roll virus isolate and its phylogenetic analysis

Total RNA was extracted from potato leaf roll virus (PLRV) positive potato plants and complementary DNA were synthesized. Reverse transcriptase polymerase chain reaction (RT-PCR) based detection conditions were optimized by using coat protein (CP) gene specific primers. A 346 bp amplicon of PLRV- coat protein (CP) gene was amplified. Amplified CP-gene of PLRV was cloned in TA cloning vector, PCR ® 2.1. The clone was confirmed subsequently through restriction digestion analysis. PCR amplification used cDNA clone as a template and nucleotide sequencing. Expected nucleotide sequence of amplified PLRV-CP gene show homology of 94 to 97% when compared to the sequences already reported in GenBank database. This explored novel PLRV-CP gene was submitted at NCBI GenBank for characterization of PLRV Pakistani isolate (Accession No. JN039286). Phylogenetic analysis was also carried out and tree was made by using MEGA 4.0.Key words: Potato, potato leaf roll virus (PLRV), coat protein (CP) gene, reverse transcriptase polymerase chain reaction (RT-PCR), PLRV-CP Pakistani isolate

Feature Fusion for Human Activity Recognition using Parameter-Optimized Multi-Stage Graph Convolutional Network and Transformer Models

Human activity recognition (HAR) is a crucial area of research that involves understanding human movements using computer and machine vision technology. Deep learning has emerged as a powerful tool for this task, with models such as Convolutional Neural Networks (CNNs) and Transformers being employed to capture various aspects of human motion. One of the key contributions of this work is the demonstration of the effectiveness of feature fusion in improving HAR accuracy by capturing spatial and temporal features, which has important implications for the development of more accurate and robust activity recognition systems. The study uses sensory data from HuGaDB, PKU-MMD, LARa, and TUG datasets. Two model, the PO-MS-GCN and a Transformer were trained and evaluated, with PO-MS-GCN outperforming state-of-the-art models. HuGaDB and TUG achieved high accuracies and f1-scores, while LARa and PKU-MMD had lower scores. Feature fusion improved results across datasets.Comment: 7 pages, 1 figure, conferenc
