QUANTITATIVE POLLEN ANALYSIS OF BEE HONEY AT CERTAIN APIARIES IN QALYUBIA GOVERNORATE AND AVAILABLE HONEY IN LOCAL MARKET, EGYPT [PDF]

open access: yesArab Universities Journal of Agricultural Sciences, 2018
A new proposal method for quantitative pollen analysis of pollen grains in each gram of bee honey was described, using aNeubauer improved chamber for leucocytes and erythrocytes counting. The study was conducted at the Bee Research Unit, Dept.

Automation of pollen analysis using a computer microscope : a thesis presented in partial fulfilment of the requirements for the degree of Master of Engineering in Computer Systems Engineering at Massey University [PDF]

open access: yes, 2004
The classification and counting of pollen is an important tool in the understanding of processes in agriculture, forestry, medicine and ecology. Current pollen analysis methods are manual, require expert operators, and are time consuming.

Chromatin Topology Reconfiguration Orchestrates Thermotolerant Male Fertility via GhAL5 in Cotton

open access: yesAdvanced Science, EarlyView.
This study investigates cotton’s high‐temperature (HT) response using multi‑omics. Dynamic 3D genome changes drive expression bias affecting male fertility. The tolerant line shows controlled chromatin dynamics, while the sensitive line exhibits overactivation.

The Late Glacial and Holocene development of vegetation in the area of a fossil lake in the Skaliska Basin (north-eastern Poland) inferred from pollen analysis and radiocarbon dating

open access: yesActa Palaeobotanica, 2013
The development of vegetation in the Skaliska Basin has been reconstructed on the basis of palynological analysis and radiocarbon dating (AMS technique) of 6 sites from the late phase of the Bolling- Allerod interstadial complex to modern times. Although

Sensitivity of the grassland-forest ecotone in East African open woodland savannah to historical rainfall variation [PDF]

open access: yes, 2014
. Fossil pollen records provide key insight into the sensitivity of terrestrial ecosystems to climate change at longer time scales. However, tracing vegetation response to relatively modest historical climate fluctuations is often complicated by the ...

Ecosystem‐Centered Robot Design: Toward Ecoresorbable Sustainability Robots (ESRs)

open access: yesAdvanced Science, EarlyView.
Robots exploring natural ecosystems can support monitoring and conservation, but must adopt ecosystem‐centered design to avoid pollution, waste, and damage. This review proposes guidelines for co‐designing ecoresorbable sustainability robots (ESRs), uniting materials, robotics, and ecological contexts in a single framework.

The palynological record of the Eemian interglacial and Early Vistulian glaciation in deposits of the Żabieniec Południowy fossil basin (Łódź Plateau, central Poland), and its palaeogeographic significance

open access: yesActa Palaeobotanica, 2014
The vegetation of the Eemian interglacial and Early Vistulian glaciation was reconstructed on the basis of pollen analysis, biogenic and mineral-biogenic sediments from the Żabieniec Południowy locality.

MDP25‐VDAC3 Complex Orchestrates Actin Remodeling and Mitochondrial Dynamics to Modulate Innate Immunity in Arabidopsis

open access: yesAdvanced Science, EarlyView.
This study reveals that actin remodeling regulates mitochondrial elongation as a defense strategy in plants. Flagellin perception induces fusion‐dependent elongation, supported by cortical actin bundles, to repair damage and boost ATP and ROS production.

Pollen analysis of a peaty mud sample from the Dunajec River alluvial fan (Sandomierz Basin, Poland) in the context of its morphological position, radiocarbon dating, and comparison with neighbouring sites

open access: yesActa Palaeobotanica, 2015
The paper presents the results of pollen analysis and radiocarbon dating of a peaty mud sample from a gravel-sand outlier of the Vistulian alluvial fan of the Dunajec River.
