Response of Dutch Fennel to Algae Extract Partial Replacement of Mineral NPK under Sinai Conditions

Two field trials were carried out during 2014/2015 and 2015/2016 seasons at the El-Maghara Research Station-Desert Research Center. , to study the effect of algae extract foliar application as partial replacement for chemical fertilization on vegetative growth, fruits yield, essential oil and its main components as well as chemical constituents of Dutch fennel under Sinai conditions. Treatments were the combination of five fertilization levels (full recommended dose of NPK only, 75, 50, 25% of the recommended NPK plus spraying with algae extract and spraying algae extract only), as treatments were arranged in a randomized complete blocks design with three replications for each treatment. The results showed that, application of T2 (75% of the recommended NPK plus algae extract) increased plant height, number of umbels, fresh and dry weights / plant and maximized the essential oil yield compared to other treatments. However, the least amount of essential oil yield was obtained in plants treated with spraying algae extract only. Application of T2 also increased the concentration of N, P and K in plant tissues, Meanwhile, T5(spraying with only algae extract) led to the lowest values compared other treatments in both seasons. As general the main chemical constituents of Dutch fennel essential oil were trans-anethole, estragole, fenchone, limonene, alpha-pinene.
Impact of EDTA, Citric Acid and Humic Acid on Phytoremedation of Metal Contaminated Soil by Indian Mustard (Brassica juncea)

A pot experiment was conducted during winter season of (2013/2014) at Sakha Agricultural Research Station, Kafr ElSheikh Governorate. The experiment aimed to investigate the effect of disodium ethylenediaminetetraacetic acid (EDTA) (0.0, 1.5, 3.0 and 4.5 mmol kg soil), citric acid (CA) (0, 3, 6 and 9 mmol kg soil) and humic acid (HA) (0.0, 0.2, 0.4 and 0.6 g kg soil) on the phytoextraction of Cu, Zn and Pb from Al-Gabal Al-Asfar contaminated soil using indian mustard (Brassica juncea) and the leaching behavior of these metals from soil. The obtained results can be summarised in the following:EDTA severely reduced indian mustard dry weight and visual symptoms of toxicity were observed, especially at 4.5 mmol EDTA kg soil. Whilst, application of CA and HA ameliorated indian mustard growth.EDTA was found to be the most efficient chelator in increasing concentrations of Cu and Zn in different indian mustard plant parts.Increasing EDTA application rate up to 4.5 mmol kg soil increased the concentrations of Cu by 1.91, 2.88, 3.04 and 1.56 folds and Zn by 1.43, 1.91, 1.83and 1.11 folds for roots, stem, leaves and seeds, respectively, compared to control treatment (0.0 mmol EDTA kg soil). Application of CA also increased Cu and Zn concentrations by different indian mustard plant parts, especially at 9 mmol kg soil, but its efficacy was less than EDTA.HA application increased Zn concentrations in different indian mustard plant parts with increasing its addition up to 0.6 g kg soil, but its efficacy was less than that of EDTA and CA.HA application did not affect Cu concentrations in indian mustard.There were neither any perceptible concentrations of Pb in different plant parts of indian mustard except for roots clarifying that phytoextraction of Pb failed even after application of tested chelators. Application of EDTA and CA to the soil increased the leaching of Cu, Zn and Pb under indian mustard cultivation with increasing application rate up to 4.5 and 9 mmol kg soil, respectively. However, the effect of EDTA was many times higher than that of CA. Whilst, HA application did not affect the leaching of studied metals.Using CA for the phytoremediation of Cu and CA and HA for the phytoremediation of Zn is favorable than EDTA despite the high efficiency of EDTA, due to the harmful effects of EDTA on plant growth and the increased risk of groundwater contamination via metal leaching.

Environmental impacts on biogenic emissions of volatile organic compounds (VOCs)

Die vorliegende Literaturstudie fasst den Stand des Wissens uber die Funktionen, Triebkrafte, und Auswirkungen von biogenen VOCs zusammen. Insbesondere wird untersucht, welche Einflusse zusatzlich zu Temperatur und Strahlung – welche seit langem bekannt sind und in Modellen abgebildet werden konnen – als bedeutsam angesehen werden. Dies sind vor allem ein direktes Einwirken von Luftschadstoffen und Trockenheit, sowie indirekte Faktoren wie das Auftreten von Insekten. Von allen diesen Einflussen wird erwartet, dass sie sich im Rahmen des Klimawandels und der Luftreinhaltepolitik andern. Allerdings wird keine dieser Triebkrafte in regionalen Emissionsabschatzungen berucksichtigt. Existierende Ansatze, die Wirkung des Trockenstresses in Modellen abzubilden vernachlassigen artspezifische Unterschiede und Veranderungen in der Zusammensetzung der Emissionen. Zusatzlich wird untersucht, inwiefern sich die existierenden Unsicherheiten bei der Bestimmung biogener Emissionen auf die Abschatzung der Luftqualitat und des regionalen Klimas auswirken. Entsprechende Informationen aus der Literatur sind jedoch kaum verfugbar.
Dopamine Metabolism Quantified in the Human Brain: Tracer Kinetic Analysis of Positron Tomographic Studies

Mathematical models are used to estimate physiological parameters which are otherwise inaccessible to measurement. When applied to tracer kinetic data obtained in positron tomographic studies, these methods allow for the quantitative analysis of regional metabolic rates in the human brain during life. Dopamine, a neurotransmitter in the mammalian central nervous system, is synthesized by the action of aromatic amino acid decarboxylase on L­ dihydroxyphenylalanine (L-dopa). A fluorinated analogue of L-dopa, 6-[1F]fluoro-L­ dopa, is used as a tracer in positron tomography to study the nigrostriatal dopaminergic system. Although this tracer has been in use in man for over ten years, a definitive method of quantitative analysis has not yet emerged. The comparison of quantitative results obtained by this approach has been confounded by the diversity of mathematical modelling techniques employed. These techniques range from simple graphical analyses, which yield a single rate constant for the entire system, to complex compartmental approaches, which may not present a unique solution. The goal of this research has been to develop an approach to quantitative analysis which is both informative and mathematically justifiable. Compartmental models of increasing complexity have been evaluated by statistical methods (F-test) to
Supercooled liquid fogs over the central Greenland Ice Sheet

Abstract. Radiation fogs at Summit Station, Greenland (72.58∘ N, 38.48∘ W; 3210 m a.s.l.), are frequently reported by observers. The fogs are often accompanied by fogbows, indicating the particles are composed of liquid; and because of the low temperatures at Summit, this liquid is supercooled. Here we analyze the formation of these fogs as well as their physical and radiative properties. In situ observations of particle size and droplet number concentration were made using scattering spectrometers near 2 and 10 m height from 2012 to 2014. These data are complemented by colocated observations of meteorology, turbulent and radiative fluxes, and remote sensing. We find that liquid fogs occur in all seasons with the highest frequency in September and a minimum in April. Due to the characteristics of the boundary-layer meteorology, the fogs are elevated, forming between 2 and 10 m, and the particles then fall toward the surface. The diameter of mature particles is typically 20–25 µm in summer. Number concentrations are higher at warmer temperatures and, thus, higher in summer compared to winter. The fogs form at temperatures as warm as −5 ∘C, while the coldest form at temperatures approaching −40 ∘C. Facilitated by the elevated condensation, in winter two-thirds of fogs occurred within a relatively warm layer above the surface when the near-surface air was below −40 ∘C, as cold as −57 ∘C, which is too cold to support liquid water. This implies that fog particles settling through this layer of cold air freeze in the air column before contacting the surface, thereby accumulating at the surface as ice without riming. Liquid fogs observed under otherwise clear skies annually imparted 1.5 W m−2 of cloud radiative forcing (CRF). While this is a small contribution to the surface radiation climatology, individual events are influential. The mean CRF during liquid fog events was 26 W m−2, and was sometimes much higher. An extreme case study was observed to radiatively force 5 ∘C of surface warming during the coldest part of the day, effectively damping the diurnal cycle. At lower elevations of the ice sheet where melting is more common, such damping could signal a role for fogs in preconditioning the surface for melting later in the day.

27 28 30 31 33 35 36 38 40 41 42 43 47 48 51 52 53 54 55 56 57 The electrochemical oxidation of theophylline was investigated by controlled potential electrolysis in two different organic solvents and in water for comparison. The anodic oxidation was monitored by cyclic voltammetry in situ and UV-Vis spectrophotometry ex situ and the final electrolyzed solutions were analyzed by tandem mass spectrometry after chromatographic separation with an HPLC-PDA-ESI-MS/MS system. The main oxidation products evidenced as the main diode array chromatographic peaks were tentatively assigned to dimeric forms of theophylline, two of which have never been reported before, on the base of retention time, UV-Vis spectrum, m / z ratio in both positive and negative ESI modes and fragmentation pattern. Two chemical paths following the primary mono-electronic anodic oxidation of theophylline to the final evidenced oxidation products have been proposed. modes, in the mass range 135–500 Da, with the following ESI source parameters: capillary voltage 3000 V, cone voltage 25 V, source temperature 120 ° C, desolvation temperature 350 ° C, cone gas flow 40 Lh @ 1 , desolvation gas flow 600 Lh @ 1 . Data acquisition, data handling and instruments control were performed by MassLynx Software 4.1 v (Data Handling System for Windows, Micromass, UK). Samples were prepared by diluting (1:100) 10 μ L of the electrolyzed solutions, in turn, with mobile phase A:B (95:5, v:v) and the filtrate (Cronus Syringe Filter 0.45 μ m) injected (20 μ L) for the analysis. All the samples were analyzed in duplicate in two independent runs. The Total Ion Chromatograms (TIC) in pESI were extracted at the [M + H] + of TPh, m / z = 181, and the corresponding peak areas were measured for current efficiency calculation. Infusion experiments were carried out in daughter mode, both in pESI and nESI, using argon as collision gas. The same samples, prepared as described above, were infused directly into the source using an external syringe pump with a set flow rate of 5 μ L min @ 1 , selecting the parent ion in turn and optimizing the collision energy (CE) value to obtain the corresponding best fragmentation pattern. In detail: [M + H] + = 215 CE 23 eV and [M @ H] @ = 213 CE 25 eV; [M + H] + = 359 CE 28 eV and [M @ H] @ = 357 CE 28 eV; [M + H] + = 378 CE 15 eV and [M @ H] @ = 376 CE 15 eV; [M + H] + = 393 CE 15 eV and [M @ H] @ = 391 CE 17 eV.

Chlorophytum microbial fuel cell characterization

ABSTRACT In the present work, solar energy conversion into electricity was evidenced by the Chlorophytum comosum-Microbial Fuel Cell (Chlorophytum-MFC). Our Chlorophytum-MFC had produced an Open Circuit Voltage (OCV) up to 1211 mV, without adding any nutrient or membrane. Plant biomass heigh and anodic bacterial number were proportional to OCV, current Icmax, and power Pmax, and were inversely proportional to the internal resistance Rint thus: 42 cm, 110.103 U/ml, 900 mV, 0.037 mA, 744 µW/m2 and 17 KΩ, respectively, at the 191th day of experiment. We had also highlighted that Chlorophytum-MFC had behaved like a typical fuel cell via polarization and power curves. Also, we had studied the photosynthesis effect on electrical energy production by measuring voltage fluctuation during three successive days and nights. The solar and temperatures influences were also highlighted by comparing weather software data to the measured Open Voltage. The electrogenous activity was clearly proportional to soil and climate temperature as well as to sunlight intensity. The obtained results showed that developing Chlorophytum-MFC could provide significant prospects for p-MFC and bioenergy recovery.

Integrative Soil Application of Humic Acid and Sulfur Improves Saline Calcareous Soil Properties and Barley Plant Performance

ABSTRACT During the 2017 and 2018 seasons, two field experiments were conducted on newly reclaimed saline calcareous soil (7.13 dS m‒1, 16.9% CaCO3) in the experimental farm of the Faculty of Agriculture, Demo, Fayoum Governorate, Egypt. The current work aimed at identifying the potential positive effects of applied humic acid (HA) and elemental sulfur (S) on some soil properties and barley plant performance. The results showed that the application of HA and/or S at different rates ameliorated the adverse effects of saline calcareous soil conditions and significantly reduced some chemical properties of the soil (e.g., pH, ECe, and CaCO3%), while soil organic matter (OM%) and some nutrients (e.g., P, Fe, Mn, Cu, and Zn) contents were significantly increased. In addition, the contents of nutrients (e.g., P, Fe, Mn, Cu, and Zn) in barley plant and yielded grain, grain content of N and protein (%), and the performance (e.g., plant height, spike length, grain and straw yields, and weight of 1000-grain) of barley plant were significantly increased with the application of HA and/or S. The best results were obtained through the integrative application of 100 kg HA + 400 kg S ha‒1 to the tested saline calcareous soil. Therefore, the integrative soil application of 100 kg HA + 400 kg S ha‒1 can be recommended for the cultivation and sustainability of crop production in saline calcareous soil, in addition to rationalize the use of mineral fertilizers, which represent a surplus point for the sustainable agriculture system.
A Virtual Dressing Room Using Kinect

We Shows a novel virtual fitting room framework using a depth sensor, which provides a realistic fitting experience with customized motion filters, size adjustments and physical simulation. The proposed scaling method adjusts the avatar and calculate a standardized apparel size according to the user's measurements, prepares the collision mesh and the physics simulation, with a total of 1 s preprocessing time. The real-time motion filters prevent unnatural artifacts due to the bug from depth sensor or self barrier body parts. We apply bone splitting to realistically render the body parts near the joints. All components are combined efficiently to keep the frame rate higher than previous works while not sacrificing realism.
Effects of Diabetogenic Agent Streptozotocin on Hematological Parameters of Wistar Albino Rats “An Experimental Study”

Background: Diabetes mellitus has remained the major concern for medical sciences researches due to its deleterious effects on general, physical and mental health of patients. To understand the pathophysiology and to explore better treatment options for such kind of metabolic disorders it is necessary to generate the experimental animal models. To create diabetic animal models, streptozotocin has shown predominance in selectivity as a diabetogenic agent. While studying effects of any intervention in the diabetic animal models, being a cytotoxic drug streptozotocin may affect the study results by inhibiting highly replicating cells especially hematopoietic cells. Aims: The aim of study was to analyze the effects of streptozotocin on various cellular components of blood such as RBCs, WBCs (Lymphocytes, Neutrophils, Eosinophils), Hb%, HCT and Platelets, at baseline, 5th day and 15th day without any intervention. Study Design: Animal based Experimental study. Place and duration of Study: The study was conducted at animal house of faculty of Pharmacy Ziauddin University Karachi, while laboratory work was performed at MDRL-1 Ziauddin University. Methodology: In Group A normal saline and in group B and C 60 mg / kg streptozotocin diluted in normal saline was administered intraperitoneally. After the confirmation of induction of Diabetes in rats, on fifth day blood samples were drawn from Group A and B and were analyzed. While blood samples from group C were drawn on fifteenth day. Results: Analysis of various hematological parameters on 5th day revealed that there was a decrease in the levels of Hb, HCT, RBCs and WBCs with an increase in platelet count in group B in comparison to group A (control). On the other hand, in Group C (15th day), blood cell counts (Hb, HCT, RBCs, WBCs, Lymphocytes, Neutrophils and platelets) seemed to recover from streptozotocin induced decline that was observed in group B, however did not reach the baselines as in group A(control). Conclusion: It is concluded that change in hematological parameters of rats after administration of streptozotocin is reversible. The blood parameters may recover near to base line values without any intervention within two weeks.
Impact of heavy metals of industrial plant wastewater on benthic communities of Bizerte Lagoon (Tunisia)

ABSTRACT The aim of this study was to assess the consequences of human impact on the characteristics of sediments heavy metal concentration, grain size and its influence on the structure of the microbial and meiofaunal community assemblages. A survey was carried out in July 2013 within six sites located in the Bizerte Lagoon (Tunisia), both downstream and upstream of industrial effluents. The highest total sediment metal concentrations were detected in stations located close to the industrial sewage discharge points. In these stations, the lowest densities of the total meiofauna (33 ± 13 ind/10 cm−2) and conversely the highest densities of cultivable bacteria that are heavy metal resistant have been reported (16 ± 80.34 CFU g−1). Univariate (ANOVA) and multivariate (MDS/CCA) analyses demonstrate high dissimilarity (0.06) in meiofaunal and bacterial community structures between downstream and upstream industrial sewages. Furthermore, canonical correspondence analysis CCA results indicated that heavy metal sediment contamination promoted bacteria that are resistant to heavy metals, while heterotrophic bacteria supported the development of meiofauna taxa. The results highlight the importance of bacteria/meiofauna interactions, as both meiofaunal and microbial communities give indications of the ecological impact of heavy metal contamination in sediment.
