Comparative efficacy of passive and mechanical fan-pad cooling system for microclimate modification and welfare in broiler production

Indian Journal of Animal Sciences, 2016
Efficacy of passive cooling vis-à-vis mechanical fan-pad cooling system was assessed for microclimate modification to alleviate heat stress and improving growth performance and welfare of broilers. Cooling treatments comprised of Tc (control without any

Effects of Reynolds number and distribution on passive flow control in owl-inspired leading-edge serrations.

Integrative and Comparative Biology, 2020
As a sophisticated micro device for noise reduction, the owl-inspired leading-edge (LE) serrations have been confirmed capable of achieving passive control of laminar-turbulent transition while normally paying a cost of lowering the aerodynamic ...

An improved passive vortex generator model for flow separation control

, 2010
Modeling arrays of passive vortex generators (VGs) pairs located in the fully turbulent boundary layer of a two-dimensional flat plate, generating streamwise counterrotating vortex structures is investigated. Usually, a sound computational fluid dynamics

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Suppression of Fluid Forces Acting on Two Square Prisms in Tandem Arrangement by Passive Control. [PDF]

The aim of the present study is to suppress the fluid forces acting on two square prisms in tandem arrangement, which is found in many cases in structures on land and in the ocean, by exerting passive control on an approaching flow using a small flat ...

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

Molecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

PANoptosis in the pathogenesis of myelodysplastic syndromes

Molecular Oncology, EarlyView.
PANoptosis, a combination of three types of programmed cell death, is mediated by a large protein complex called a PANoptosome. In healthy bone marrow hematopoietic cells, PANoptosis is restricted by inhibitory signaling. In MDS, bone marrow cells become sensitive to the PANoptotic stimuli due to the aberrant inactivation of inhibitory signaling or ...

Passive Control Measures of Wind Flow around Tall Buildings

Buildings
The growth and diversification of tall buildings demands higher performance standards that encompass serviceability and resilience. In this respect, the control of air flow around tall buildings poses challenges to minimising the energy that could induce

Effects of Active and Passive Control Techniques on Mach 1.5 Cavity Flow Dynamics

International Journal of Aerospace Engineering, 2017
Supersonic flow over cavities has been of interest since 1960s because cavities represent the bomb bays of aircraft. The flow is transient, turbulent, and complicated. Pressure fluctuations inside the cavity can impede successful weapon release.

NAPRT loss promotes lung tumor initiation and growth through AKT signaling independently of NAD+ biosynthesis

Molecular Oncology, EarlyView.
Loss of NAPRT promotes lung tumor initiation and growth through a noncanonical mechanism, independent of its role in NAD+ biosynthesis. Mechanistically, NAPRT depletion activates the mTORC2‐driven AKT/β‐catenin signaling axis to enhance clonogenic and invasive phenotypes. Furthermore, lung‐specific Naprt deletion significantly increases tumor burden in
