Investigation of dynamic quality changes and optimization of drying parameters of carrots (Daucus carota var. laguna)
(2019-11-29)
The effect of air temperature and sample thickness on the color changes and total carotenoids content of carrot slices was investigated. Temperature, exposure time, and moisture levels significantly affected the dynamic changes of total carotenoids and color. A slow and linear decrease in total carotenoids was observed at higher moisture content until reaching an inflection point at around 0.45 gw/gdm for all temperatures studied. Thereafter, the retention in total carotenoids decreased rapidly. The highest retention ...

An Analysis of Water Awareness Campaign Messaging in the Case of Jordan: Water Conservation for State Security
(2019-06-01)
This article examines water awareness campaign messaging of the Water Efficiency and Public Information for Action (WEPIA) campaign. Using Jordanian government documents and structured interviews, it argues that the Ministry of Water and Irrigation (MWI) promotes water awareness campaigns to shape water users’ habits and perspectives on water. The goal of this strategy is to align popular concerns about water security with government concerns over state security, i.e., to create responsible water citizens. This article ...

Superfruit in the Niche - Underutilized Sea Buckthorn in Gilgit-Baltistan, Pakistan
(2019-10-21)
Sea buckthorn is a medicinal plant occurring throughout the temperate regions of the northern hemisphere. Considered as a “superfood” given the nutritional properties of its berries, the latter have a large international market potential, particularly in China and Europe. Although sea buckthorn grows widespread in northern Pakistan, it is a neglected species there. Fruit marketing is severely hampered by low raw product quality, varying prices, and low local demand. During 2017–2018 a total of 111 collectors and 17 ...

Application of Arthrospira (Spirulina) platensis against Chemical Pollution of Water
(2019-08-23)
The basis of phytoremediation technology for cleaning chemically polluted water was developed in the framework of the presented work. This technology is based on the ability of blue-green alga Arthrospira platensis to eliminate different environmental toxicants from water. This technological approach was conducted for the following pollutants: 1,1,1-trichloro-2,2-bis(4-chlorophenyl)ethane (DDT), 2,4,6-trinitrotoluene (TNT), and cesium ions. The effectiveness of the technology was tested in model experiments, which ...

Nitrogen turnover in a repeatedly manured arid subtropical soil: Incubation studies with 15N isotopes
(2019-07-23)
Under the hot and moist conditions of irrigated agriculture in the arid subtropics, turnover of organic matter is high, which can lead to considerable carbon (C) and nitrogen (N) losses. Therefore, sustainable use of these soils requires regular manure application at high rates. To investigate the contribution of consecutive manure applications to an arid sandy soil to various soil N pools, goat manure was isotopically labeled by feeding 15N‐enriched Rhodes grass hay and applied to the soil during a two‐year field ...

Heterogeneous Winter Wheat Populations Differ in Yield Stability Depending on their Genetic Background and Management System
(2019-11-05)
Twelve winter wheat composite cross populations (CCPs), based on three genetic backgrounds and maintained at the University of Kassel, Germany, under both organic and conventional management, were assessed for yield performance and stability in comparison to two commercial varieties over eight and 10 experimental years. A number of stability parameters were chosen in order to identify populations with either adaptation to specific environments or broad adaptation across environments. The genetic effects of the CCP ...

Toward Science-Based and Knowledge-Based Targets for Global Sustainable Resource Use
(2019-08-06)
The article discusses key aspects to be considered for the orientation of sustainable resource policies. Resource management at the local scale needs to be supplemented by governmental action in order to adjust production and consumption toward acceptable levels of global resource use. What is acceptable is being informed by scientific findings on environmental degradation and relevant cause–effect relationships. However, the desired state of the environment, the tolerable level of uncertainties about environmental ...

Beyond spikes: Multiscale computational analysis of in vivo long-term recordings in the cockroach circadian clock
(2019-09-23)
The circadian clock of the nocturnal Madeira cockroach is located in the accessory medulla, a small nonretinotopic neuropil in the brain’s visual system. The clock comprises about 240 neurons that control rhythms in physiology and behavior such as sleep-wake cycles. The clock neurons contain an abundant number of partly colocalized neuropeptides, among them pigment-dispersing factor (PDF), the insects’ most important circadian coupling signal that controls sleep-wake rhythms. We performed long-term loose-patch clamp ...

Multi-Temporal Monsoon Crop Biomass Estimation Using Hyperspectral Imaging
(2019-07-27)
Hyperspectral remote sensing is considered to be an effective tool in crop monitoring and estimation of biomass. Many of the previous approaches are from single year or single date measurements, even though the complete crop growth with multiple years would be required for an appropriate estimation of biomass. The aim of this study was to estimate the fresh matter biomass (FMB) by terrestrial hyperspectral imaging of the three crops (lablab, maize and finger millet) under different levels of nitrogen fertiliser and ...

A New Identity for Generalized Hypergeometric Functions and Applications
(2019-01-18)
We establish a new identity for generalized hypergeometric functions and apply it for first- and second-kind Gauss summation formulas to obtain some new summation formulas. The presented identity indeed extends some results of the recent published paper (Some summation theorems for generalized hypergeometric functions, Axioms, 7 (2018), Article 38).
