Occupational Exposure to Talc Increases the Risk of Lung Cancer: A Meta-Analysis of Occupational Cohort Studies

Canadian Respiratory Journal, 2017
Objective. Talc is widely used in industrial applications. Previous meta-analyses of carcinogenic effects associated with inhaled talc included publications before 2004, with a lack of data in China, the largest talc-producing country.

Chest ultrasonography to assess the kinetics and efficacy of talc pleurodesis in a model of pneumothorax: an experimental animal study

ERJ Open Research, 2018
Talc pleurodesis is used to avoid recurrences in malignant pleural effusions or pneumothorax. The lack of lung sliding detected by chest ultrasonography (CUS) after talc application is indicative of the effectiveness of pleurodesis.

Outgassing of Ordinary Chondritic Material and Some of its Implications for the Chemistry of Asteroids, Planets, and Satellites [PDF]

, 2006
We used chemical equilibrium calculations to model thermal outgassing of ordinary chondritic material as a function of temperature, pressure, and bulk compositions and use our results to discuss outgassing on asteroids and the early Earth.

Thirty years of glyphosate‐resistant crops and weeds: Current situation and future prospects

Pest Management Science, Volume 82, Issue 7, Page 5987-6009, July 2026.
Since 1996, when the first glyphosate‐resistant crop was commercialized and the first resistant weed was reported, resistance has expanded globally. This review analyzes emergence patterns across weed species, crops, regions, resistance mechanisms, and herbicides.

Blending methodologies in talc operations [PDF]

, 1996
The problem posed by Western Mining Corporation involves finding a way of improving or optimising the utilisation of batches of lower grade talc when making up orders for products of different grades. During the MISG a number of Linear Programming models

Effects of pupal hypoxia duration and holding temperature on quality control parameters of sterile Queensland fruit fly

Pest Management Science, EarlyView.
Queensland fruit fly pupae tolerate hypoxia up to 2 days without compromising quality. Prolonged hypoxia, especially at 25 °C, reduces emergence and flight ability. Storage at 18 °C is recommended. Abstract BACKGROUND The sterile insect technique is used to eradicate outbreaks of Queensland fruit fly (Q‐fly) Bactrocera tryoni (Froggatt) in fruit‐fly ...

Crystallization and Melting Behavior of Biodegradable Poly(L-lactic acid)/Talc Composites

E-Journal of Chemistry, 2012
Crystallization and melting behavior of Poly(L-lactic acid)(PLLA)/Talc composites with different talc content were investigated in detail. The addition of talc can increase the overall crystallization rate of PLLA, 5%talc makes the melt-crystallization ...

Evidence for two-dimensional nucleation of superconductivity in MgB$_{2}$ [PDF]

, 2002
According to the crystal structure of MgB$_{2}$ and band structure calculations quasi-two-dimensional (2D) boron planes are responsible for the superconductivity.

Posidonia oceanica Leaves as a Natural Filler for Poly(Butylene Succinate‐Co‐Adipate) Composites: Characterization and Biodegradation Assessment in Seawater

Journal of Vinyl and Additive Technology, EarlyView.
This study shows that incorporating 5–10 wt.% Posidonia oceanica, with or without micro‐talc, in PBSA preserves thermal stability, modifying crystallization behavior, and maintains good filler dispersion and interfacial adhesion. Mechanical properties are moderately stiffened.

Sedimentary talc in Neoproterozoic carbonate successions [PDF]

, 2014
Mineralogical, petrographic and sedimentological observations document early diagenetic talc in carbonate-dominated successions deposited on two early Neoproterozoic (~ 800–700 million years old) platform margins.
