The Assessment of Soil Physico-Chemistry and Uptake of Heavy Metals in Lumbricus Terrestris
No full textEarthworms are considered ecosystem engineers, playing an essential role in soil fertility. Heavy metals are supposed to remain linked to soil for a very long time and can bio-accumulate swiftly in soil microbes, posing a severe threat to the environment. The current study was designed to investigate the bio-accumulation of heavy metals in Lumbricus terrestris and the impact of soil pH and texture on earthworm morphology and densities near industrial areas of the district of Okara, Punjab, Pakistan. The samples were collected from the locations of different industries using the quadrate method and analyzed for heavy metal accumulation by using atomic absorption spectrometry. It was observed that the earthworm specimens collected from experimental sites have maximum zinc (in sites 1, 2, 3, 4 and 5 as 172.25±0.94, 162±0.71, 146.25±0.94, 137.83±1.03, and 151.08±0.74 respectively) and minimum lead (in site 1, 2, 3, 4 and 5 as 20.92±0.74, 23.25±0.94, 17.58±0.59, 16±0.71, and 14.33±1.08 respectively) accumulation and varies non-significantly with the control site. It was also observed that pH 8.1 (site 2, loamy soil) had the lowest earthworm density compared to the other sites (Clay soils). The observed weight and length of the Earthworm were as (max. 2.386 grams and min. 0.38 grams) and (max. 19 cm and min. 2.5 cm) respectively. It is concluded that soil biochemistry affects the morphology and distribution pattern of earthworms, whereas heavy metals cause severe environmental damage. The present study will provide baseline data for the conservation of soil biota and enhance crop yield for a tremendously increasing population

The Northern Lapwing (Vanellus Vanellus Linnaeus, 1758), A New Species in the List of Charadriidae in the Western Steppes of Algeria
Get PDFThis manuscript aims to authenticate the presence of a species of wild bird: Northern Lapwing (Vanellus vanellus Linnaeus, 1758), which represents a first in the western steppes areas of Algeria. The sighting was recorded in the treated wastewater treatment plant west of the municipality of Mécheria. The phonological status of this species can be classified as a passing visitor. This presence can be justified by the food rules of the Northern Lapwing (Vanellus vanellus Linnaeus, 1758) which is insectivorous and finds in this area prey on which it feeds

NASA\u27s Human Contributions To Safety Data Testbed
Get PDFNASA’s System-Wide Safety (SWS) Project conducted a high-fidelity flightsimulation study and curated a publicly available data and analysis coderepository, referred to as the Human Contributions to Safety (HC2S) Data Testbed.Publication of the HC2S Data Testbed data descriptor publication in the NatureScientific Data journal provides a detailed description of the research dataset aswell as methodological procedures, data management, and analysis approaches.The purpose of the HC2S Data Testbed is to enable empirical assessment ofresilient pilot behaviors and broaden the understanding of human contributions tosafety in commercial aviation. By framing safety as the capacity to succeed undervarying conditions, this work contributes directly to emerging concepts in Safety-IIand advances development of an In-time Aviation Safety Management Systems(IASMS)
Comparing Post-Run and Retrospective Minute-by-Minute Workload Scores
Get PDFWhen we ask participants to evaluate their workload in a real or contrived scenario it isunknown how they quantify their response. This uncertainty compounds when the scenariois long and has several subtasks. Thus, it is difficult to determine what the workload scoresindicate. The questions arise: Are participants reporting a peak level of workload? Somesort of aggregate? In this paper, we aim to correlate NASA Task-Load Index (TLX) scoresobtained during a contrived scenario in a flight simulator with minute-by-minute measuresof workload. We describe the strength and direction of correlations between the twoworkload ratings and determine if there is a consistent categorical score (e.g., maximumminute-by-minute workload) that represents the post-run TLX. The goal of this work is toprovide guidance to those that prefer to run longer human-in-the-loop simulations so thereis confidence in the data and understanding of the TLX scores
