Sustainable Production Planning: Insights Into Factors, Models, and Solution Methods
Sustainable Development, EarlyView.ABSTRACT Effective resource management remains a major challenge for organizations seeking to balance economic efficiency with environmental and social responsibility. In this context, production planning becomes a strategic mechanism for integrating sustainability into industrial operations.

How Long-lived Grains Dominate the Shape of the Zodiacal Cloud
The Planetary Science JournalGrain–grain collisions shape the three-dimensional size and velocity distribution of the inner Zodiacal Cloud and the impact rates of dust on inner planets, yet they remain the least understood sink of zodiacal dust grains. For the first time, we combine

Long-term orbital evolution of short-period comets found in Project Cosmo-DICE [PDF]
, 1992 Orbital evolutions of about 160 short-period (SP) comets are numerically integrated for 4400 years in the framework of a realistic dynamical model. By the round-trip error in closure test, a reliable time space of the integrated orbits is estimated for ...

Cytogenotoxic Effects of Fluopyram in Allium cepa Root Cells Involving Microtubule Disruption
Environmental Toxicology, EarlyView.ABSTRACT Fluopyram is a next‐generation fungicide widely used in agriculture; however, its persistence in soils and mobility toward aquatic systems have raised concerns regarding potential ecotoxicological risks. This study evaluated the cytogenotoxic effects of a commercial fluopyram‐based pesticide formulation on Allium cepa root meristem cells ...

On the Early Thermal Processing of Planetesimals during and after the Giant Planet Instability
The Planetary Science JournalBorn as ice-rich planetesimals, cometary nuclei were gravitationally scattered onto their current orbits in the Kuiper Belt and the Oort Cloud during the giant planets’ dynamical instability in the early stages of our solar system’s history.

Cytogenotoxic and Molecular Assessment of Pyrethrins on Non‐Target Allium cepa Roots
Environmental Toxicology, EarlyView.ABSTRACT The pyrethrins, which form a part of naturally occurring insecticidal chemicals derived from chrysanthemum flowers, not only provide rapid knockdown of a broad spectrum of insect pests but are also widely used in integrated pest management due to a generally favorable safety profile, largely attributed to low mammalian toxicity.

Nongravitational Forces in Planetary Systems
The Planetary Science JournalNongravitational forces play surprising and, sometimes, centrally important roles in shaping the motions and properties of small planetary bodies. In the solar system, the morphologies of comets, the delivery of meteorites, and the shapes and dynamics of

Weather, EarlyView.The English language is a gargantuan, gluttonous beast. It has become extraordinary in its powers of assimilation – such that we rarely consider the origins of the words we use. In this paper, we will shed light on these origins, including the Pontic–Caspian steppe, the British Empire and, of course, a TV show.

Near-IR Spectroscopic Analysis of the Primary Volatile Composition of Long and Short-Period Comets [PDF]
, 2023 Comets are among the most well-preserved objects that formed in the protosolar nebula ∼4.5 Gyr ago. Hence, they are important for understanding various aspects of the formation, evolution, and habitability of the solar system. Multiple primary volatiles (

Nongravitational forces on comets [PDF]
, 1976 Methods are presented and discussed for determining the effects of nongravitational forces on the orbits of comets. These methods are applied to short-period and long-period comets.
