Abstract
The current study focuses and emphasis on the potential of heat stress to negatively affect crop physiology. Here, we have screened 19 wheat (Triticum aestivum L.) genotypes for their tolerance of heat stress. Significant differences were observed among the genotypes for all the traits under consideration. Exploitable extent of genetic variability amongst the entries was present as revealed by considerably higher estimates of mean %. On the basis of Heat susceptibility Index, Halna, Mon’s Ald’s, genotypes Cuo/79/Prulla and K 307 were identified as heat-tolerant whereas SAWSN 3041, SAWSN 3101 and K 0583 were identified as heat-susceptible. The 17 wheat microsatellite markers were capable of detecting 89 alleles with an average of 4.6 alleles per locus. Polymorphism Information Content value ranged from 0.16 for the primer XGWM 516 to 0.83 for DUPW 117 with an average of 0.60. A perusal of similarity coefficients clearly reflected that a very high degree of similarity exists between wheat variety Mon’s Ald’s and SAWSN 3101 (0.70). On the other hand, the two most distantly related cultivars were found to be AKAW 4008 and PBW 343 (0.034). BARC 4, BARC 170, BARC 311, PSP 3058, WHE014.H04 and GWM 458 were strongly associated with the heat tolerance for traits TGW and BARC 311 was strongly associated with terminal heat tolerance for number of grains/plant respectively. Considering all the parameters it is adjudged that relatively stable genotypes may be evaluated at various agro climatic regions for grain yield and heat tolerance along with other contributing characters and ideal plant type.

A Note on the Perturbation of arithmetic expressions
Authors: Journal Baghdad Science 
Published: March 2019

In this paper we present the theoretical foundation of forward error analysis of numerical algorithms under;•	Approximations in "built-in" functions.•	Rounding errors in arithmetic floating-point operations.•	Perturbations of data.The error analysis is based on linearization method. The fundamental tools of the forward error analysis are system of linear absolute and relative a prior and a posteriori error equations and associated condition numbers constituting optimal of possible cumulative round – off errors. The condition numbers enable simple general, quantitative bounds definitions of numerical stability. The theoretical results have been applied a Gaussian elimination, and have proved to be very effective means of both a priori and a posteriori error analysis.

Authors: Journal Baghdad Science 
Published: March 2019

Sixty albino female mice were used in this experiment to study the possible effect of the crude alcoholic extract of the celery leaves on their fertility. These animals were randomly and equally divided into three experimental groups (20 females/group). The first and second groups were orally given a daily dose of 500 and 1000 mg/kg body weight, respectively, of the crude alcoholic extract, while the third group (control) was similarly treated, at the same time, with 0.1 ml/gm body weight of physiological saline for comparison. The treatment, however, lasted for 25 consecutive days.
On day 26, after treatment was stopped, the life body weight of all animals was recorded before sacrificing the animals. Thereafter blood samples were collected by heart puncture for hormonal (estrogen, progesterone, luteinizing hormone and follicle stimulating hormone) determination. Reproductive organs (ovaries and uteri) were also isolated and preserved for histological studies.
Active ingredients in the extracts were analytically tested. The test gave positive results for flavonoids, steroids, tannins and terbenoids.
The effect of the extract on the studied parameters which are related to the fertility is reflected in the following results:

Formulation, Characterization and In vitro Cytotoxicity of 5-Fluorouracil Loaded Polymeric Electrospun Nanofibers for the Treatment of Skin Cancer
Authors: Patel Gayatri , Yadav Bindu K.N. 
Published: March 2019

Background:
The purpose of this study was to formulate, characterize and conduct in vitro
cytotoxicity of 5-fluorouracil loaded polymeric electrospun nanofibers for the treatment of skin cancer.
The patents on electrospun nanofibers (US9393216B2), (US14146252), (WO2015003155A1) etc.
helped in the selection of polymers and method for the preparation of nanofibers.

Methods:
In the present study, the fabrication of nanofibers was done using a blend of chitosan with
polyvinyl alcohol and processed using the electrospinning technique. 5-fluorouracil with known
chemotherapeutic potential in the treatment of skin cancer was used as a drug carrier. 24-1 fractional
factorial screening design was employed to study the effect of independent variables like the
concentration of the polymeric solution, applied voltage (kV), distance (cm), flow rate (ml / hr) on dependent
variables like % entrapment efficiency and fiber diameter.

Results:
Scanning electron microscopy was used to characterize fiber diameter and morphology. Results
showed that the fiber diameter of all batches was found in the range of 100-200 nm. The optimized
batch results showed the fiber diameter of 162.7 nm with uniform fibers. The tensile strength
obtained was 190±37 Mpa. Further in vitro and ex vivo drug release profile suggested a controlled release
mechanism for an extended period of 24 hr. The 5-fluorouracil loaded electrospun nanofibers
were found to decrease cell viability up to ≥50% over 24 hr, with the number of cells dropping by ~
10% over 48 hr. As the cell viability was affected by the release of 5-fluorouracil, we believe that electrospun
nanofibers are a promising drug delivery system for the treatment of Basal Cell Carcinoma
(BCC) skin cancer.

Conclusion:
These results demonstrate the possibility of delivering 5-Fluorouracil loaded electrospun
nanofiber to skin with enhanced encapsulation efficiency indicating the effectiveness of the formulation
for the treatment of basal cell carcinoma type of skin cancer.

Abstract
Reform of the Chinese petroleum industry has entered its second phase since early 1999. The productivity of the petroleum industry has been greatly improved, while the safety performance and records are not satisfactory. This paper investigates the critical factors for improving safety performance in the Chinese petroleum industry. The data used for the analysis are from a questionnaire survey administered to 480 professionals in the petroleum industry in which 143 valid responses were received. Statistical analysis techniques are used to analyze the data collected. The findings revealed that the most significant source of the safety problem is due to the combination of several reasons, including (a) violation on operating procedures, (b) obsolete facilities and equipment failures, (c) insufficient safety management system, (d) improper commands, number of casualties, and (e) production performances and operating skills. The three most essential protective methods include safety training and increasing staff’s safety consciousness, cultivating safety culture, and enhancing equipment management and detecting hazards in time.

A internet é ponto chave neste artigo, pois se analisa a formação de escritoras brasileiras tendo como elemento propulsor de suas carreiras o advento de blogs e sites de divulgação de textos lésbicos. Objetivou-se, a partir da análise desta trajetória específica, compreender o processo de transição de escritores do mundo digital para o impresso, assim como a sua relação com estes dois tipos de publicação (virtual e física). Analisou-se a trajetória de vida desta escritora, buscando traçar pontos de continuidade e de descontinuidade na experiência de ser uma escritora pertencente a uma minoria sexual e que tem sua escrita voltada para este público.
La pesadilla de Descartes
Authors: González Requena Jesús 
Published: March 2019

En el presente trabajo sostenemos que en el núcleo de la escritura -y de la pasión- de ese filósofo esencial de la Modernidad que fue Descartes se halla presente, literalmente, una pesadilla. Y sostenemos, igualmente, que la índole de esa pesadilla permite dilucidar la contradicción que se manifiesta presente en la expresión "sujeto moderno".
Para ello, procedemos al análisis de las líneas mayores de la filosofía cartesiana: su radical critica de las filosofías anteriores, su voluntad de construir el método de la ciencia, la adopción de las matemáticas y la geometría como disciplinas de referencia en las que logra aislar la autonomía y la productividad del significante, el papel de la duda y el momento negativo que la caracteriza, la construcción de un modelo del sujeto concebido como máquina de inteligibilidad…
Finalmente, analizamos el famoso sueño de Descartes como una pesadilla directamente vinculada al devenir de su filosofía y reveladora tanto de la personal experiencia dramática del filósofo como de los impases del sujeto contemporáneo.
