Generative AI use in entrepreneurship: An integrative review and the Empowerment–Entrapment Framework

open access: yesStrategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary Despite the growing use of generative artificial intelligence (GenAI) in entrepreneurship, research on its impact remains fragmented. To address this limitation, we provide an integrative, entrepreneur‐centered review of how GenAI influences entrepreneurs at each stage of the entrepreneurial process: (1) opportunity ...

Influence of Implant Surface Topography on Primary Stability in a Standardized Osteoporosis Rabbit Model Study

open access: yesJournal of Functional Biomaterials, 2015
Evaluating primary stability is important to predict the prognosis of dental implant treatment. Primary stability is decreased in a low bone density site such as osteoporosis.

Primary stability and osseointegration comparing a novel tapered design tissue-level implant with a parallel design tissue-level implant. An experimental in vivo study. [PDF]

open access: yes
OBJECTIVES: The aim of the present study was to compare a novel tapered, double-threaded self-tapping tissue-Level design implant (TLC) to a well-established parallel walled tissue-level (TL) implant in terms of primary and secondary stability over time.

Framing the unknowable: The role of language and frame multiplicity in early‐stage startup pitches

open access: yesStrategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary Early‐stage startup pitches must make largely unknowable futures plausible. As such, they bear a rhetorical burden. This study theorizes how multiple frames jointly shape this burden and, consequently, affect investor evaluations. Specifically, it considers how future growth frames interact with concreteness and novelty frames.

Sequential Reduction of Chromite Pellets Using Hydrogen and Silicon Carbide for Carbon Emission Abatement During Ferrochrome Production

open access: yessteel research international, EarlyView.
H2 prereduction selectively metallizes Fe in UG2 chromite pellets at 1100°C, while silicon carbide becomes active at 1300°C to convert remaining Cr2O3 to carbides and promote Cr metallization. By separating the roles of H2 and SiC, the sequential route reaches up to 65.7% Cr metallization and suppresses in‐furnace CO generation by ≈75% versus ...

Effects of implant length and 3D bone-to-implant contact on initial stabilities of dental implant: a microcomputed tomography study

open access: yesBMC Oral Health, 2017
Background The influences of potential bone-to-implant contact (BIC) area (pBICA), BIC area (BICA), and three dimensional (3D) BIC percentage (3D BIC%; defined as BICA divided by pBICA) in relation to the implant length on initial implant stability were ...

The influence of implant diameter, length and design changes on implant stability quotient (ISQ) value in artificial bone

open access: yes, 2012
Purpose : The purpose of this study is to ascertain the stability of the implant by comparing the effects of the change of implant diameter, length and design on implant stability quotient.

Diflubenzuron Caused Mitochondrial Dysfunction, Ca2+ Homeostasis Disruption, and Intrinsic Apoptosis in Trophoblastic Cells

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Diflubenzuron is used as an insect growth inhibitor, and its potential risk to human health was raised owing to the possibility of environmental residues and human exposure. This study aimed to investigate the toxic mechanism of diflubenzuron on trophoblastic cells such as HTR8/SVneo and JEG‐3 cells. We investigated mitochondrial function, Ca2+

Assessment of Metal Contamination and Human Health Risk in the Buffalo River Estuary, Eastern Cape, South Africa

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Metal contamination in estuarine environments poses environmental and public health concerns, particularly where surface waters support domestic and subsistence uses. This study assessed the seasonal distribution, controlling mechanisms, and non‐carcinogenic health risks of selected metals (Mg, Al, Ba, Fe, Mn, and Zn) in the Buffalo River ...

Magnetothermal‐responsive drug release bone cement based on EGFR‐mutated lung cancer bone metastases

open access: yesVIEW, EarlyView.
A novel magnetothermal‐responsive bone cement was developed by integrating PMMA/CPC/Osimertinib matrix with Fe3O4@SiO2@Zol nanomaterials. This dual‐drug system achieves controlled release, combining excellent mechanical properties with potent anti‐tumor activity and bone regulation for treating EGFR‐mutated LC‐BoM.
