Hopelessness can be consider as a subtype of depressions, it can be defined as having no expectation of good or success, giving no ground for hope, incapable of solution management or accomplishment .

Hopelessness is one of psychological variables that distinguish negative personalities because there are positive correlation between hopelessness and variables such as : anxiety, depression, suicide thought and so on .

One of the important variables correlate with hopelessness is low self-esteem, many studies indicate that there are statistically significant inverse relationship between the two variables, the present study aimed to :

1. Measures hopeless

Field experiment carried out at Nubaria Agricultural Research station, National Research Centre, Egypt to study the role of antitranspirants application{Salicylic Acid (SA), K₂SO₄ and MgCO₃} in alleviating drought-induced changes of some sensitive barley varieties. Foliar application of the antitranspirants compounds registered a positive effect on plant pigment, relative water content, nutrient contents and proline accumulation under water stress condition especially after spraying SA. The barley varieties Tamellalet and Giza 125 highly responded to antitranspirants application especially after foliar application of SA and MgCO

Writing in English language demands both mental skills and a suitable level of language proficiency. Some studies showed that writing anxiety has an impact on the acquisition of language learning. This study; however, teaches the cognitive strategies (PLAY & WRITE) as a writing strategy, so as to decrease students’ use of it when experiencing writing anxiety at the academic writing level. The sample has been (100) second-stage Department of English learners at the College of Education (Ibn –Rushd), in the University of Baghdad-Iraq. They have been randomly selected and divided into experimental and control groups; (50) students in each group. To achieve the objective of the study, SLWAI questionnaire has been distributed to the e

The effects of using aqueous nanofluids containing covalently functionalized graphene nanoplatelets with triethanolamine (TEA-GNPs) as novel working fluids on the thermal performance of a flat-plate solar collector (FPSC) have been investigated. Water-based nanofluids with weight concentrations of 0.025%, 0.05%, 0.075%, and 0.1% of TEA-GNPs with specific surface areas of 300, 500, and 750 m2/g were prepared. An experimental setup was designed and built and a simulation program using MATLAB was developed. Experimental tests were performed using inlet fluid temperatures of 30, 40, and 50 °C; flow rates of 0.6, 1.0, and 1.4 kg/min; and heat flux intensities of 600, 800, and 1000 W/m2.

This study was aimed to compare between the effects of different chemical forms of Zn and cupper[ionic forms (CuSO4), (Zn SO4) and chelated forms of [Cu Zn (II) HEDTA and Cu (II) HEDTA], whereas, HEDTA is N-(hydroxyethyl) ethylenediamine triacetic acid, applied at micromolar concentrations in the nutrient solution] of Phaseolus Vulgaris plants grown hydroponically under conditions of iron deficiency (- Fe) were investigated. Plant variants (– Fe + 2 µM Cu²⁺) and (– Fe+ 20 µM Zn²⁺⁾ with extremely strong chlorosis were examined for investigations to take after the recuperation of leaf greening after treatment with Cu(II)HEDTA created leaf greening in the two variations, particularly strong for t

This study was aimed to measure the decolorization of tattoo dyes by different chemicals and polyphenol oxidases from several plant sources. The tattoo inks removal market has burgeoned over the years, due to increased spread of tattooed persons about the world. Laser and surgery are presently the gold standards for removing of the tattoo. However, both of them have blemishes. Consequently, lots of persons were preferring easier, faster and cheaper procedures for tattoo remove. In this study polyphenol oxidases enzyme from many plant sources and different chemicals were used for decolorization of tattoo dyes in vitro. The polyphenol oxidase enzyme was used for removing of tattoo dyes (brown and blue) in order to demonstrate their

The present study was aimed to investigate the polymorphism of the myostatin gene and its relation with some growth traits,included feed conversion rate and efficiency, protein intake and protein efficiency ratio in 68 specimens of common carp Cyprinus carpio. Sequencing of single nucleotide polymorphism (SNP) showed three genotypes at site T2230C in the myostatin gene. The distribution rates were 5.88, 38.24 and 55.88% for TT, TC and CC respectively, and the variation among them was high significant, the allelic frequency was 0.25 for allele T, while it was 0.75 for C. Effect of the genotype of the myostatin gene was significantly in the feed conversion rate and efficiency, the protein intake and the protein efficiency

This study was conducted by using18 Awassiewes , 2-4 years aged, with average body weight 61.56 kg. The ewes  were randomly divided into three groups, six ewes in each group. All ewes received 1.5 kg/ dry matter  from the same basal diet  consist mainly of barley, wheat bran, soybean meal and wheat straw . The first group was fed on basal  ration only ( T1 ) ,while  45g /ewe /day sodium bicarbonate was  supplemented to the feed of  the second (T2)group and third (T3) group was supplemented with 45g sodium bicarbonate plus 0.5g mixture of Vitamin E and selenium /ewe/day. Results showed that the treatments hadsignificant increase( P < 0.05 ) on milk production of T3(739 g/d) than T1,T2(571and 5

The aim of this study was to reduce the lodging and improve grain yield by evaluation the performance of some oat cultivars introduced into Iraq. A field experiment was conducted during two seasons of 2017-2018 and 2018-2019, included four cultivars (Genzania, Shafa, Carrolup and Hamel) under the influence of foliar spraying of ethephon at concentrations of 0, 500 and 1000 ppm, and foliar application of boron with concentrations of 0, 50 and 100 ppm. Using RCBD within split–split arrangement and three replicates. The results were revealed that Genzania was recorded the highest number of grains head^-1 and grain yield

This work describes the enhancement of phenol red decolorization through immobilizing of laccase in chitosan and enzyme recycling. Commercial laccase from white rot fungus, Trametesversicolor (Tvlac), was immobilizedin to freshly prepared chitosan beads by using glutaraldehyde as a cross linker. Characterization of prepared chitosan was confirmed by FTIR and scanning electron microscope (SEM). Tvlac (46.2 U/mL) immobilized into chitosan beads at 0.8 % glutaraldehyde (v/v) within 24 hrs. Synthetic (HBT) and natural (vanillin) mediators were used to enhance dye decolorizoation. It was found that 89 % of phenol red was decolorized by chitosan beads within 180 min. in the absence of enzyme and mediator, while decolorization percenta
