Quantification of Morphological Characteristics of Aggregates at Multiple Scales
Properties of aggregates are affected by their morphological characteristics, including shape factors, angularity and texture. These morphological characteristics influence the aggregate's mutual interactions and strengths of bonds between the aggregates and the binder. The interactions between …

Functional and Morphological Characteristics of Smooth Muscle in the Rat Vagina
The vagina is an essential organ of the female reproductive system that has been largely understudied in the field of biomechanics. The ability of the vagina to contract gives rise to a set of active mechanical properties that contribute to the complex function of this organ in-vivo. After briefly …

Photosynthesis and certain morphological characteristics of alfalfa as affected by potassium nutrition
The enhancing effect of K on alfalfa (Medicago sativa L.) yield has frequently been reported, but the nature of this influence has not been clearly shown. It was assumed that K contributed either to increased leaf expansion, thereby resulting in a larger photosynthetic surface, or to higher CO₂ …

Examining external morphological characteristics of Lucilia sericata pupae for age estimation in medico-legal investigations
… estimation. This study aims to identify reliable morphological markers to aid in a more accurate age estimation of Lucilia sericata during the pupal stage. A total of 145 pupae were collected and examined for external morphological changes over time. Five pupae were collected at each time point. A …

Contribution of crop morphological characteristics and density of selected crops to weed species composition and suppression
A field study was conducted at Lincoln University during the 1999-2000 growing season to investigate the effect of crop species and sowing density on weed dynamics, productivity and species composition. Crops with a spreading (narrow-leafed lupin, Lupimus augustifolius and dwarf French bean, …

Effects of elevated testicular temperature on viability of cryopreserved semen and morphological characteristics of ejaculated spermatozoa
… Viability (motility and acrosome integrity) and morphological characteristics of sperm before and after thermal insult were examined. For assessment of results, collection days were grouped: days -6, -3, 0 = Period 1 (d 0 = day of testis coverage after semen collection on that day), days 3, 6, 9 …
