Comparison Between Groundwater Quality at North East and South West of Erbil Governorate for Irrigation Using Some Global Systems and Principal Component Analysis

Received : 10/6/2020 Final Revision : 6/7/2020 Abstract: This investigation was conducted during June ,2019 to November ,2019 for classification of water of (54) wells in Erbil province 26 of them in north and north east of Erbil and the other half at south west of Erbil. The studied waters were classified for irrigation purpose depending on some global systems or classification and Principal component analysis was done for the calculated parameters used in classification. Depending on USDA classification(1954) the water of the water of (20 and 6) locations or wells having C2S1 and C3S1 Class respectively . While for the south east Erbil wells the water classes were C1S1, C2S1 , C3S1 and C4S1 for (1,5,17, and 3) wells it means the water quality in south west of Erbil west is bad in comparing with the water for wells in north and north east of Erbil. Depending Ayres and Westcot (1985) and Doneen classification the water wells in north and north east of Erbil had better water classes in comparing with the groundwater in south west of Erbil. ,. A scree plot for eigenvalues recorded in this investigation showed the pronounced change of slope after the third eigenvalue. Eigenvalue close or greater than one (unity) were three factors for north and north east of Erbil and two factors for water of south west of Erbil due to its higher EC value.
Overproduction of ABA in rootstocks alleviates salinity stress in tomato shoots.

To determine whether root-supplied ABA alleviates saline stress, tomato (Solanum lycopersicum L. cv. Sugar Drop) was grafted onto two independent lines (NCED OE) overexpressing the SlNCED1 gene (9-cis-epoxycarotenoid dioxygenase) and wild type rootstocks. After 200 days of saline irrigation (EC = 3.5 dS m-1 ), plants with NCED OE rootstocks had 30% higher fruit yield, but decreased root biomass and lateral root development. Although NCED OE rootstocks upregulated ABA-signalling (AREB, ATHB12), ethylene-related (ACCs, ERFs), aquaporin (PIPs) and stress-related (TAS14, KIN, LEA) genes, downregulation of PYL ABA receptors and signalling components (WRKYs), ethylene synthesis (ACOs) and auxin responsive factors occurred. Elevated SlNCED1 expression enhanced ABA levels in reproductive tissue while ABA catabolites accumulated in leaf and xylem sap suggesting homeostatic mechanisms. NCED OE also reduced xylem cytokinin transport to the shoot and stimulated foliar 2-isopentenyl adenine (iP) accumulation and phloem transport. Moreover, increased xylem GA3 levels in growing fruit trusses were associated with enhanced reproductive growth. Improved photosynthesis without changes in stomatal conductance was consistent with reduced stress sensitivity and hormone-mediated alteration of leaf growth and mesophyll structure. Combined with increases in leaf nutrients and flavonoids, systemic changes in hormone balance could explain enhanced vigour, reproductive growth and yield under saline stress.

Pollution Permits and Financing Costs

Effective environmental policy should consider how the financiers of polluting firms behave. In a theoretical model describing the periods before and after policy implementation, we show that loan spreads for firms participating in cap-and-trade programs are a function of the costs of compliance and the specific features of the permits markets. With higher permits storage and lower permit prices, firm financing costs fall. Our empirical analysis exploits the dichotomy created by phase III of the EU Emission Trading System, designed to increase and pass the cost of Carbon dioxide emissions to the polluters. In contrast with possible program intentions but in line with our theoretical predictions, loan spreads fall by 25% on average starting in 2013. We empirically identify permits storage before program implementation and its associated effect as key drivers of the fall in loan spreads for affected firms, and we show that this dynamic partly undermines the expected reduction in Carbon dioxide emissions.
Effects of Diclofenac on the embryonic development of freshwater crayfish

In recent years, there has been increasing concern about the ecotoxicological consequences of the drug Diclofenac on freshwater organisms. Influences on the largest freshwater invertebrates, the freshwater crayfish, are especially interesting in the context of cascading effects due to their important role as keystone species. In this study, lethality, influences on body weight, embryonic development and histological changes in embryos of marbled crayfish (Procambarus virginalis) as well as noble crayfish (Astacus astacus) were investigated in response to their exposure to different concentrations of Diclofenac. Additionally, the suitability of marbled crayfish as a model organism for endemic freshwater crayfish was established when studying the effects of Diclofenac. For both species, lethal effects started at concentrations of 10.24 mg/L Diclofenac, weight was not affected, embryonic development slowed down from concentrations of 0.16 mg/L and histological changes were visible from concentrations of 0.64 mg/L. The similarity of LOEC (Lowest Observed Effect Concentrations) between the two species showed that marbled crayfish can serve as a model for native crayfish when investigating the effects of exposure to Diclofenac.
A Survey of DDoS Attack Detection Strategies in Cloud

Cloud is known as highly-available platform that has become most popular among businesses for all IT needs. Being widely used platform, it’s also a hot target to cyber-attacks. Distributed Denial of Services (DDoS) is a great threat to cloud in which cloud bandwidth, resources and applications are attacked to cause service unavailability. In a DDoS attack, multiple botnets attack victims using spoofed IPs with a huge number of requests to a server. Since its discovery in 1980, numerous methods have been proposed for the detection and prevention of network anomalies. This study provides a background of DDoS attack detection methods in the past decade and a survey of some of the latest proposed strategies to detect DDoS attacks in the cloud, the methods are further compared for their detection accuracy.
A sticky thicket of glue cells: A comparative morphometric analysis of colloblasts in 20 species of comb jelly (phylum Ctenophora)

Ctenophores in the class Tentaculata are distinct from Cnidarians in that they use sticky, not stinging, tentacles to capture and subdue their prey. The structures that make these tentacles sticky are colloblasts, specialized multicellular adhesive structures for predation. Located on the tentacles, tentacle side-branches (tentilla), or oral tentilla, colloblasts are only found in comb jellies (phylum Ctenophora). To perform comparative anatomy of the diversity of ctenophore colloblasts, specimens were collected from the epito bathypelagic zones near the coasts of central California and the Hawaiian Islands using blue-water divers and remotely operated vehicles. Tentacle samples were immediately fixed in a 4% formalin solution at sea, and then prepared in the lab via secondary fixation in 2% OsO4 for scanning electron microscopy (SEM). Diversity of ultrastructural characteristics was observed using SEM, and the morphometrics of the collosphere, external secretion granules, and spiral filament were recorded for 20 species, within 9 families and 9 genera, including 13 undescribed species. Morphometry of colloblasts reveals that the shape of the collosphere (the organizational unit of sticky granules) falls into 3 classifications: spherical, ellipsoidal, or non-uniform. External secretion granule deposition falls into 2 categories: clustered or patterned; the cap cell membrane was either present or absent. This morphological variation is summarized graphically and will be useful to describe the functional diversity and feeding ecology of the interesting and controversial phylum Ctenophora.
Boredom, alexithymia, and desire thinking in eating disorders: a cross-sectional study

Background: Eating disorders (ED) can be considered in terms of affective disorders. In this perspective, abnormal eating behaviors would be dysfunctional defensive behaviors related to difficulties to recognize and modulate traumatic emotional experiences. The aim of this study is to explore the associations between alexithymia, boredom, impulsiveness, and desire thinking in subjects with eating disorders. Methods: 45 patients with ED and 45 healthy controls completed the following questionnaires: Toronto Alexithymia Scale, Barratt Impulsiveness Scale, Multidimensional State Boredom Scale, Desire Thinking Questionnaire, Body Uneasiness Test and Somatoform Dissociation Questionnaire. Results: Our results seem to confirm that alexithymia, boredom, impulsivity, and desire thinking are strictly related in ED. In particular, difficulties in identifying feelings contribute to determine boredom experiences which, in turn, contribute significantly to structure body image disorders. Conclusions: This study adds new insights into the associations between alexithymia, boredom, impulsiveness, and desire thinking in subjects with eating disorders. Future areas of investigation could better explore the role of boredom experiences in structuring body image dissatisfaction and its relationship with alexithymia.
Glycinebetaine-Induced Alteration in Gaseous Exchange Capacity and Osmoprotective Phenomena in Safflower (Carthamus tinctorius L.) under Water Deficit Conditions

Several inorganic and organic compounds including glycine betaine (GB) are presently being used as an exogenous application to enhance tolerance in plants to different environmental stresses. The current study assessed to what extent exogenously applied GB could improve the gaseous exchange capacity and primary and secondary metabolites in two accessions (16178 and 16180) of safflower (Carthamus tinctorius L.) plants under drought stress. Three-week-old plants of both safflower accessions were subjected to well-watered (control) or water-deficit conditions (60% field capacity (FC)). Three levels of GB (control, 50 mM and 100 mM) were sprayed to the foliage of the control and stressed plants after one month of drought application. After two weeks of foliar application of GB, gas exchange characteristics and other biochemical parameters were determined. The results showed that water deficiency markedly suppressed plant biomass, chlorophyll contents, photosynthesis rate (A), water use efficiency (A/E), stomatal conductance (gs) and relative water contents (RWC) of both accessions of safflower, while it enhanced the levels of osmolytes (GB and proline), hydrogen peroxide (H2O2) and total phenolics. Foliar application of GB was effective in enhancing the plant biomass, chlorophyll contents, gs, sub-stomatal CO2 concentration (Ci), Ci/Ca ratio, osmolytes, H2O2, ascorbic acid (AsA), total phenolics and RWC in safflower plants under water shortage. Thus, exogenous application of GB could be used as an effective strategy to improve plant growth, photosynthetic attributes and secondary metabolites in safflower plants under water deficit conditions.
Latent Changes in Perceived Quality of Sleep Related to the COVID-19 Quarantine Measures in Italian University Students: Understanding the Role of Personality and Internalizing Symptoms

The present online retrospective study aimed at evaluating the perceived sleep quality before the start of the lockdown measures and during the lockdown in a sample of Italian university students ( N = 307). Participants were administered the Italian translation of the Pittsburg Sleep Quality Index (PSQI), the Beck Depression Inventory (BDI), the Beck Anxiety Inventory (BAI), and the Personality Inventory for DSM-5 36-item version (PID-5-36) in order to assess the relationships between sleep, dysfunctional personality domains and internalizing symptomatology. Latent difference factor (LDF) model was used to estimate latent change in PSQI scores; all analyses on the relationships between the PSQI and the dysfunctional personality domain measures and internalizing symptoms were carried out using latent factor scores. Our findings showed that selected dysfunctional personality traits were significantly associated with changes in perceived quality of sleep among adult university students during the lockdown in Italy. The relationship between PID-5-36 Negative Affectivity and changes in the perceived quality of sleep was only partially mediated by the severity of self-reported depression. The assessment of perceived depressive symptom severity and Negative Affectivity may prove clinically useful for carrying out preventive interventions on sleep quality.
Hydraulic Modelling Analysis for Road Stormwater Drainage Evaluation under RCPs‎ Based Rainfall Data

Road drainage systems are often-constructed utilised design approaches not incorporating process-based depictions of possible hydrological responses, resulting in insufficient systems due to infrastructural development and climate change and ultimately, increased hydrological reaction. This study assessed possible effects of precipitation intensity variation following future severe rainfall events on the current road drainage system as whether pre-climatic stormwater drainage system could withstand potentially higher discharges and the need for modified design guidelines incorporating possible precipitation intensity variations due to ‎climate change. A case study was undertaken utilising rainfall data to develop an intensity-duration-frequency (IDF) curve representing precipitation volume variations due to climate change. The peak discharge and water level were simulated using hydraulic software program SWMM 5.1 for the existing open drainage system, wherein three future potential climate scenarios, namely 2030, 2040, and 2050 were simulated based on the RCP4.5 and RCP8.5 scenarios. The simulation results showed a tremendous future precipitation increment for RCP4.5 and RCP8.5 scenarios, yielding the following values, respectively: 28.8%, ‎‎43.7% and 34.6% and 65%, 61.5% and 75.5%. Therefore, the study findings and approach implemented should be considered when detailing assessments and preserving areas are at risk of high water flows. The study concludes that the existing road drainage system's inadequacy to manage copious rainfall amounts ‎anticipated due to climate change. Therefore, the study contributes to suggest the need for developing ‎drainage system magnitude using higher return periods to mitigate flood levels ‎on urban road networks.

The development of Petunia hybrida corolla was divided into five phases.The content changes of anthocyanin,reducing sugar and solutable protein in petals during the flower development are investigated respectively. The results showed that the content of anthocyanin and reducing sugar reached to the highest at the beginning of blooming(phase IV). During the development of petals , the trend between the production of anthocyanin and content of reducing sugar was similar. Of the three color flowers, the anthocyanin content in the purple petal was the highest.
Scattering from phase-separated vesicles. I. An analytical form factor for multiple static domains

This is the first in a series of papers considering elastic scattering from laterally heterogeneous lipid vesicles containing multiple domains. Unique among biophysical tools, small-angle neutron scattering can in principle give detailed information about the size, shape and spatial arrangement of domains. A general theory for scattering from laterally heterogeneous vesicles is presented, and the analytical form factor for static domains with arbitrary spatial configuration is derived, including a simplification for uniformly sized round domains. The validity of the model, including series truncation effects, is assessed by comparison with simulated data obtained from a Monte Carlo method. Several aspects of the analytical solution for scattering intensity are discussed in the context of small-angle neutron scattering data, including the effect of varying domain size and number, as well as solvent contrast. The analysis indicates that effects of domain formation are most pronounced when the vesicle's average scattering length density matches that of the surrounding solvent.
PubMIUR: a Tool for On-line Assisted Bibliographic Researches

Several kinds of user can be interested in scientific publication references produced by academic organizations. Sometimes references are arranged in HTML pages, separated one for an year, and a database containing them can not be available. Results of executed query using this framework couldn't be satisfying. We developed a web-based system to assist user making query, inside web pages, using different search criteria. The constrain on querying one year at a time and the lack of a database is so overcame.
Open project-based learning for dynamic adaptability of IT education

The pace of technological change is accelerating, the duration of the trends is becoming shorter and the number of technological alternatives to solve IT problems grows quickly. Keeping IT higher education course curricula up-to-date becomes more and more challenging. This paper presents an empirical study that aims to assess whether an open-statement and open-solution methodology in an IT-related project-based learning (PBL) course led to the adaptation of the skills learned by students to the trends of the main IT technology domains. The study analyses data from more than 90 projects by students from eight academic years of the course” Project on Information Technologies”, carried out by students in the last year of the Bachelor of Science in Informatics Engineering at the Barcelona School of Informatics. Our results identify a high correlation between the technologies chosen in student projects and technological trends, which shows that the methodology encourages students to incorporate the latest technological innovations in their project work plan.
Modification methods of polyethersulfone membranes for minimizing fouling - Review

Membrane Fouling was considered as major drawback in various industrial applications. Thus, this paper reviews the surface modification of polyethersulfone (PES) membranes for antifouling performance. Various modification techniques clearly indicate that hydrophilicity has to improve on the PES membrane surface. Moreover, the mechanism of fouling reduction with corresponds to various modification methods is widely discussed. Incorporation of hydrophilic functional groups on PES membrane surface enhances the surface free energy thereby which reduces the fouling. Characterization techniques adopted for the surface modified membranes was also discussed. These studies might be useful for the other researchers to utilize the modification technique for the applications of waste water treatment, chemical process industry and food industry.

A Coherence Analysis Model for English Essay Based on Sentence Semantic Graph

Aiming at the problem that cannot be solved by the entity-based graph model, we propose a new discourse coherence quality analysis model (sentence semantic graph) by merging entity graph and semantic similarity graph of the text. Firstly, we use an improved coreference resolution module to process the coreference phenomenon in the text, and build a new type of entity graph with the processed results; secondly, we merge the entity graph and the semantic similarity based on the semantic space and get our sentence semantic graph lastly, we analyze the average outdegree of sentence semantic graph to indicate the degree of text coherence. Experiments show that this model is superior to the entity-based graph model and has a good effect on the automatic evaluation of English essay.
Parameter extraction of solar photovoltaic modules using various optimization techniques: a review

Parameter extraction of the solar module is essential for performance analysis, efficiency calculation and maximum power point tracking (MPPT) in the PV system. This paper makes a detailed analysis of parameter extraction from the solar PV system through application of optimization techniques based on single and two-diode models. The characteristics of PV panel are investigated using power-voltage (P-V) and current-voltage (I-V) curves. To identification of circuit model parameters of PV panel has been done by its representation of an electrical equivalent circuit which consists of a current source in parallel with diodes. The important parameters of solar PV system are Photo current (Iph ), Reverse saturation current (Io/Io1and Io2), Diode ideality factor (A/A 1 and A 2), Series resistor (Rs ) and parallel resistor (Rp ). The difficulties in extracting parameters from solar PV modules are referred to as parameter estimation problems and form the focus for many researchers. This paper may be useful for researchers and PV panel designers in making precise PV panels with the help of suitable optimization techniques available in the literature.
