COMMON FIXED POINT THEOREMS FOR L-FUZZY MAPPINGS IN b-METRIC SPACES
ALI, JAVID,AHMED, M.A.,NAFADI, H.A. The Korean Society for Computational and Applied M 2017 Journal of applied mathematics & informatics Vol.35 No.3
In this paper, we prove common fixed point theorems for $\mathcal{L}$-fuzzy mappings under implicit relation in b-metric spaces. Further, results obtained for an integral type contractive condition. These theorems generalize and improve previous corresponding results.

In this paper, we utilize an implicit relation to improve and extend some strict common fixed point results of the existing literature to two pairs of hybrid mappings in 2-metric spaces via altering distances. As an application, we also prove some strict common fixed point theorems for hybrid pairs of mappings satisfy- ing a contractive condition of integral type in 2-metric spaces.

UNIFYING A MULTITUDE OF COMMON FIXED POINT THEOREMS EMPLOYING AN IMPLICIT RELATION
Ali, Javid,Imdad, Mohammad Korean Mathematical Society 2009 대한수학회논문집 Vol.24 No.1
A general common fixed point theorem for two pairs of weakly compatible mappings using an implicit function is proved without any continuity requirement which generalizes the result due to Popa [20, Theorem 3]. In process, several previously known results due to Fisher, Kannan, Jeong and Rhoades, Imdad and Ali, Imdad and Khan, Khan, Shahzad and others are derived as special cases. Some related results and illustrative examples are also discussed. As an application of our main result, we prove an existence theorem for the solution of simultaneous Hammerstein type integral equations.

APPROXIMATION OF FIXED POINTS AND THE SOLUTION OF A NONLINEAR INTEGRAL EQUATION
Faeem Ali,Javid Ali,Rosana Rodr´ıguez-L´opez 경남대학교 기초과학연구소 2021 Nonlinear Functional Analysis and Applications Vol.26 No.5
In this article, we define Picard’s three-step iteration process for the approximation of fixed points of Zamfirescu operators in an arbitrary Banach space. We prove a convergence result for Zamfirescu operator using the proposed iteration process. Further, we prove that Picard’s three-step iteration process is almost T-stable and converges faster than all the known and leading iteration processes. To support our results, we furnish an illustrative numerical example. Finally, we apply the proposed iteration process to approximate the solution of a mixed Volterra-Fredholm functional nonlinear integral equation.
Diversity and habitat preferences of amphibians and reptiles in Pakistan: a review
Waqas Ali,Arshad Javid,Ali Hussain,Syed Mohsin Bukhari 국립중앙과학관 2018 Journal of Asia-Pacific Biodiversity Vol.11 No.2
Geographical position of Pakistan is unique, and country harbors two out of six zoogeographical regions. The country can be divided into 15 habitat types in three major divisions: the mountainous region, foothills, and Indus plains. Overall, 219 species including 24 amphibians and 195 reptiles have been reported so far. Out of these, nine amphibian and 13 reptilian species are endemic to Pakistan. Despite this richness, there is paucity of knowledge regarding diversity of amphibians and reptiles as very few species have been thoroughly studied and very small area has been explored. This has led to the uncertainties regarding distribution and taxonomy of these taxa in the country. The herpetofauna is not protected by law in the country, and their conservation status is yet to be evaluated. Furthermore, distribution ranges of amphibians and reptiles have been changed and systemized survey work is required to update baseline information in the country.

The plant species of genus Nepeta are used totreat various human diseases and for ornamental purposesas well. Nepethalate B (1) was isolated as a result ofphytochemical investigations of Nepeta clarkei and wassubjected in the present study for investigation of analgesic,anti-inflammatory, and central nervous system (CNS)depressant activities. The percentage inhibition in phase Iof the acetic acid induced writhing test of compound 1(dose of 0.1, 0.2 and 0.4 mg/kg of body weight) was 53.3,58.0 and 86.7 % respectively. These results were foundsignificantly higher (P\0.01) as compared to the negativecontrol. Moreover, the percentage inhibitions of threephases for 0.1, 0.2 and 0.4 mg/kg were higher than thevalues obtained for Aspirin (positive control). In formalintest, the percentage pain inhibition between 0 and 5 min(early phase) was 68.0, 25.5, and 75.5 % for 0.1, 0.2 and0.4 mg/kg intra-peritoneal doses of compound 1 respectively. In case of late phase (20–30 min) it was 63.0, 66.7and 48.1 %, respectively. In comparison to aspirin, overallpercentage inhibition of compound 1 was significantlyhigher in early and late phases. Interestingly, at all dosescompound 1 showed more potent anti-inflammatory effectsin terms of intensity and duration as compared to aspirin. The gross behavioral study of nepethalate B (1) was alsocarried out and the results revealed that it exhibited CNSdepression in the mice and showed a prominent decrease inlocomotor activity.
Confirmed resistance to aryloxyphenoxypropionate herbicides in Phalaris minor populations in Iran
Gherekhloo, Javid,Mohassel, Mohammad H. Rashed,Mahalati, Mehdi Nassiri,Zand, Eskandar,Ghanbari, Ali,Osuna, Maria D.,Prado, Rafael De The Korean Society of Weed Science and The Turfgra 2011 Weed Biology and Management Vol.11 No.1
Phalaris minor (littleseed canary grass) is a major weed in wheat fields in some parts of Iran. Diclofop-methyl, fenoxaprop-P-ethyl, and clodinafop-propargyl are three acetyl coenzyme A carboxylase (ACCase)-inhibiting herbicides that are commonly used to control this grass in wheat fields. Thirty-four P. minor populations with suspected resistance to ACCase-inhibiting herbicides were sampled from wheat fields in the provinces of Fars and Golestan in Iran. The dose.response assays that were conducted under controlled greenhouse conditions indicated that 14 populations were resistant to fenoxaprop-P-ethyl, seven populations were resistant to both fenoxaprop-P-ethyl and diclofop-methyl, and three populations were resistant to fenoxaprop-P-ethyl, diclofop-methyl, and clodinafop-propargyl. These populations showed different levels of resistance to the applied herbicides, compared to the susceptible population. These results suggest that different mechanisms of resistance could be involved. The enzyme assay revealed that the existence of modified ACCase in the three most-resistant populations (AR, MR4, and SR3) is responsible for the resistance of these populations.
