Development of a Transient Model of a Lightweight, Portable and Flexible Air-Based PV-T Module for UAV Shelter Hangars

open access: yesEnergies, 2020
This research paper introduces a mathematical model to predict the performance of photovoltaic–thermal systems (PV-T), based on a thin layer flexible panel and an air pipe, by using the Trnsys® software tool to simulate energetic systems.

A Case of Juvenile Giant Fibroadenoma of Breast: A Diagnostic Dilemma

open access: yesInternational Journal of Anatomy Radiology and Surgery, 2023
Fibroadenomas are the most common type of breast tumours diagnosed in young women. Fibroadenomas found in children and adolescents are termed as juvenile fibroadenomas of which giant fibroadenomas are rare account for 0.5%-2% of all fibroadenomas, that ...

Invasive Cystic Hypersecretory Carcinoma of Breast: A Rare and Under Diagnosed Variant of Ductal Carcinoma [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2017
Handful cases of invasive Cystic Hypersecretory Ductal Carcinoma (CHC) have been reported so far in literature. Cystic hypersecretory lesions of breast have a spectrum of morphological features ranging from Cystic Hypersecretory Hyperplasia (CHH), CHH ...

Lumping and splitting [PDF]

open access: yesScience, 2018
Next month, the National Postdoctoral Association will convene its annual meeting in Cleveland, Ohio, where, among many topics, the matter of how data can inform policies to improve post-Ph.D. career pathways will be discussed. Many such data are indeed “out there,” but a major question is whether they are accessible and usable—which brings me to the ...

Development of a Transient Model of a Stirling-Based CHP System

open access: yesEnergies, 2013
Although the Stirling engine was invented in 1816, this heat engine still continues to be investigated due to the variety of energy sources that can be used to power it (e.g., solar energy, fossil fuels, biomass, and geothermal energy).

Compact lumps [PDF]

open access: yesEPL (Europhysics Letters), 2015
We study the presence of lumplike solutions in models described by a single real scalar field with standard kinematics in two-dimensional spacetime. The results show several distinct models that support the presence of bell-shaped, lumplike structures which may live in a compact space.

Abundant lump-type solutions for the extended (3+1)-dimensional Jimbo–Miwa equation

open access: yesResults in Physics, 2021
In this work, we research the mixed lump–kink solutions and their dynamic properties of the extended (3+1)-dimensional Jimbo–Miwa equation. Mixed lump–kink solutions are triggered by the interaction between lump soliton and exponential function, the ...

A lump in the buttock

open access: yesThe British Journal of Radiology, 2001
A 57-year-old man was referred to the surgical unit following the discovery by his osteopath of a mass in the left buttock. The patient had complained of left-sided sciatica radiating to the foot for 18 months. He gave a 1 month history of buttock pain and there was a noticeable buttock lump. There was no history of trauma. The past medical history was
