Khalilullah “Padishah of the Pen:Royal Scribe and Ambassador of Shah ‘Abbas and Ibrahim ‘Adil Shah II
No full textThe calligrapher Mir Khalilullah, also known as Mir Khalil Bakharzi, was from the city of Bakharz in Khurasan. This could explain why Muhammad Salih Isfahani (d. 1714) called him Mir Khalil Haravi and Ghulam Muhammad Haft Qalami Dihlavi (d. 1823) described him as a sayyid (“Mir” signaling sayyid). In some biographical accounts and historical chronicles, the given name and pen name of Khalilullah have been mistaken, due to confusion stemming from the calligrapher’s variant signatures. In his Futuhat-i ‘Adil Shahi (Conquests of the ‘Adil Shahs, 1054/1645), for example, Hashim Beg “Fuzuni” Astarabadi (appendix, chap. 1, no. 47) variously gives him three titles: Shah (king), Shah Khalilullah (King Khalilullah), and Shah Khalilullah-i “But-Shikan” (King Khalilullah the “Idol Destroyer” or “Iconoclast”)
Between tradition and modernity : the quatrains by Khalilullah Khalili
No full textThe quatrain (ruba'i) is one of the most popular classical Persian literary genres. Its master lived between the 11th and 12th AD – Omar Khayyam, whoperfected the art of keenly observing reality and commenting upon it. His quatrainsreflect a bitter-sweet picture of the meaningful(/less)ness of the human existence. Theformal features of the ruba'i developed by Khayyam provided a model for the next generations of artists, including an Afghan poet – Khalilullah Khalili (1907–1987). The source of Khalilullah's ruba'i topics should be thus sought in the poetry of Omar Khayyam that, undoubtedly, refers to Khalilullah's complicated life, full of twists and turns. Some examples indicate that Khalilullah attempted to modernize the genre and to adapt its modernized form to the needs of the contemporary times. In this way he involuntarily became an artist who returned to Afghan poetry one of its leading means of expression – the quatrain
Kinetics and improvement of biodiesel oxidative stability by a natural antioxidant from Brucea Javanica seeds / Khalilullah
Full text linkThe study was conducted to determine antioxidant activity of Brucea javanica seed and test
its potential to be used as natural antioxidant for biodiesel. 2, 2-diphenyl-1-picrylhydrazyl
(DPPH), Ferric Reducing antioxidant Power (FRAP) and Metal Chelating Assay are the
methodologies used to test antioxidant activity. The results indicated that higher flavonoids
and phenolic contents could be detected in ethyl acetate and methanol extracts as compared to
hexane extract. Ethyl acetate extract of B.javanica seed showed highest DPPH inhibition
activity up to 90% with (IC50= 31.2 g/ml). On the other hand, methanol extract had a highest
FRAP activity (0.180 ±0.03 mmol Fe2+ /g extract) with 71% inhibition. In the metal chelating
assay, ethyl acetate extract indicated the highest chelating activity with 59% inhibition
(IC50=299 g/ml). In addition, the bioactive compounds were also analysed using LCMS and
GCMS for confirmation. The chemical compounds found in B. javanica seed extract were
brevifolin, ellagic acid, gallic acid, quinic acid, strictinin, O-methyl ellagic acid,
protocatechuic acid and ellagic acid isomers from LCMS analyses. 35 chemical have been
identified in GCMS analyses. In order to confirm anti-oxidation effect of B. javanica seed
extract, rancimat and thermal oxidation tests were performed at 110oC and 80oC respectively.
For rancimat test, Gallic acid showed the highest oxidative stability of biodiesel up to 69
hours induction period (IP). However, on the other end, ethyl acetate crude extract at 1000
ppm suggested better stability up to 6h in thermal oxidation test. While, kinetics evaluation
showed a high degree of correlation coefficient (R2 =0.9) confirming that the degradation of
antioxidant in improving oxidative stability of biodiesel follows first order kinetics

Retraction Note: Laparoscopic repair of vesicovaginal fistulae with a transperitoneal approach at Universitas Gadjah Mada Urological Institute: a case report
No full textThe Editor-in-Chief has retracted this case report because Figure 3a and Figure 3b are the same as Figure 2 and Figure 3 respectively in [1] which describes a different patient, and the text of the background and discussion sections shows overlap with [1,2,3,4]. Said Alfin Khalilullah and Prahara Yuri agree with this retraction. Indrawarman Soeroharjo and Raden Danarto have not responded to correspondence from the publisher about this retraction
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Evaluation of physico-chemical properties, fatty acid compositions and biodiesel characteristics of Brucea javanica and Hibiscus sabdariffa seed oils as sustainable biofuel / Khalilullah
Full text linkThe biodiesel demand in worldwide is expected to rise sharply in the future because of its environmental friendly and renewable nature. Recently, biodiesel is mostly produced from edible feedstocks such as soybean, sunflower and palm oil. However, the competition of edible oil sources as food versus fuel makes edible oil not an ideal feedstock for biodiesel production. Biofuel production from non-edible plant seed oils is one of the effective way to anticipate the problems associated with fuel scarcity, food versus energy crisis and environmental pollution. In this study, exploration of the alternative non-edible feedstocks such as Brucea javanica seed oils (BJO) and Hibiscus sabdariffa seed oils (HSO) were investigated to be used for the production of biodiesel. Transesterification parameters such as methanol to oil ratio, temperature, catalyst and agitation were optimized by using Box-Behnken experimental design based on response surface methodology (RSM). The analysis of different oil properties, fuel properties and optimization of transesterification parameters for both feedstocks were investigated. The physicochemical properties of BJO investigated were found to be at the refractive index of 1.85, ultrasonic speed of 1.34 ms-1, acid value of 4.546 mg KOH/g, oxidative stability of 3 h according to the rancimat test and kinematic viscosity was of 17.428 mm2/s. On the other hand, HSO properties were refractive index of 2.16, ultrasonic speed of 1.52 ms-1, acid value of 5.486 mg KOH/g, oxidative stability of 3.48 h according to the rancimat test and the kinematic viscosity of 14.228 mm2/s. When converted into biodiesel using RSM experimental design, the optimum parameters found for converting Brucea javanica seed oils to biodiesel were 65 oC temperature, 1 % catalyst and 6:1 methanol to oil ratio with the highest yield of 94.34 %. In the case of Hibiscus sabdariffa seed oils, a methanol to oil ratio of 6:1, temperature 67.5 oC, catalyst 1% with a yield of 93.01 % were found to be the optimum parameters. The fuel properties of biodiesel produced were within the range of international standards such as EN14214 and ASTM standards of biodiesel except for the oxidative stability. To increase oxidative stability of the obtained biodiesel, the effectiveness of different antioxidants such as gallic acid (GA), tert-butyl-4-methylphenol (BHT), butylated hydroxyanisole (BHA), propyl gallate (PY) and t-butyl hydroquinone (TBHQ) were evaluated. All the antioxidants showed an improvement in the induction period of biodiesel with propyl gallate showing the highest efficiency in improving the oxidative stability of biodiesel up to 70 h. Both the feedstocks were successfully converted into biodiesel and a high biodiesel yield could be obtained using optimized transesterification parameters. Hence, it could be concluded in this study that non-edible feedstocks such as Brucea javanica and Hibiscus sabdariffa seed oils are suitable for biodiesel production that meets with the quality requirements of international standards as well as non-conflicting with food production
