Lean Implementation in Jordanian Pharmaceutical Industry: The Case of Hikma Company

The purpose of this paper was to investigate the effect of lean practices on productivity at process industries; the case of Hikma Pharmaceutical Company.  A quantitative approach based on survey questionnaire was used to evaluate the impact of lean tools on productivity. The paper showed that visual management, 5S, and work standards had a significant impact on productivity, whereas, waste reduction did not have a significant effect. Keywords: Lean practices, productivity, pharmaceutical industry

Rereading Al-Tabari through Al-Maturidi: New light on the third century hijri

MakaleErken dönem tefsir tarihindeki en önemli iki sima olan Ṭaberī ve Mātürīdī’ninaynı dönemde yaşamaları ve büyük oranda aynı problemlerle karşı karşıya kalmaları nedeniyle hem benzer konulardaki yaklaşımları hem de birbirlerine karşı konumları merak konusu olmuştur. Ṭaberī öncesi tefsīr tarihinde her ne kadar Muḳātil b. Süleyman gibi günümüze tefsirleri ulaşabilmiş isimler zikredilse de Ṭaberī’nin tefsir tarihi üzerindeki şekillendirici etkisi kuşkusuz daha büyük olmuştur. Ṭaberī merkeze alınarak oluşturulan tefsir tarihi, yararları olduğundan daha fazla kayıplara neden olmuştur. Hicri üçüncü asrın Ṭaberī zaviyesinden görülmesi, Ṭaberī’yi tanımamızda etkili olduğu kadar Ṭaberī’nin aynı dönemde dışarıdan nasıl görüldüğünü bilmemizi de engellemiştir. Yazar tarafından bu problemi aşabilmenin, aynı dönemdeki başka bir müfessirin gözüyle dönemi okumakla mümkün olabileceği düşünülmektedir. Elinizdeki bu makale, yayımlandığı tarih itibariyle Batıda yapılan Ṭaberī merkezli tefsir çalışmalarının geldiği noktayı özetlediği ve üçüncü yüzyıla yönelik alışılmışın dışında bir okuma önerdiği için tercüme edilme gereği duyulmuştur.As al-Ṭabarī and al-Māturīdī, the two most important figures in the history of early Qur’anic Exegesis, lived in the same period and faced the same problems to a large extent, both their approaches to similar issues and their positions against each other have been a matter of curiosity. Although names such as Muqātil b. Sulaymān whose exegesis have survived to the present are mentioned in the history of exegesis before al-Ṭabarī, the shaping effect of etkisiaberi on the history of tafsir was undoubtedly greater. The history of Qur’anic Exegesis, which was created by putting al-Ṭabarī in the center, has also caused more losses than its benefits. The fact that the third century of Hijri was seen from the al-Ṭabarī’s perspective was effective in our recognition of al-Ṭabarī as well as preventing us from knowing how al-Ṭabarī was seen from outside in the same period. It is thought by the author that it is possible to overcome this problem by reading the period through the eyes of another commentator in the same period. This article at hand,as of the date of its publication, it shows the point where the Western Qur’anic Exegesis studies made in the West and suggests an unusual reading for the third century, for this reason, it was necessary to be translate

Adaptive Processing of Spatial-Keyword Data Over a Distributed Streaming Cluster

The widespread use of GPS-enabled smartphones along with the popularity of micro-blogging and social networking applications, e.g., Twitter and Facebook, has resulted in the generation of huge streams of geo-tagged textual data. Many applications require real-time processing of these streams. For example, location-based e-coupon and ad-targeting systems enable advertisers to register millions of ads to millions of users. The number of users is typically very high and they are continuously moving, and the ads change frequently as well. Hence sending the right ad to the matching users is very challenging. Existing streaming systems are either centralized or are not spatial-keyword aware, and cannot efficiently support the processing of rapidly arriving spatial-keyword data streams. This paper presents Tornado, a distributed spatial-keyword stream processing system. Tornado features routing units to fairly distribute the workload, and furthermore, co-locate the data objects and the corresponding queries at the same processing units. The routing units use the Augmented-Grid, a novel structure that is equipped with an efficient search algorithm for distributing the data objects and queries. Tornado uses evaluators to process the data objects against the queries. The routing units minimize the redundant communication by not sending data updates for processing when these updates do not match any query. By applying dynamically evaluated cost formulae that continuously represent the processing overhead at each evaluator, Tornado is adaptive to changes in the workload. Extensive experimental evaluation using spatio-textual range queries over real Twitter data indicates that Tornado outperforms the non-spatio-textually aware approaches by up to two orders of magnitude in terms of the overall system throughput

Formation of Ammonium Nitrate Aerosols by Gas-Phase Reaction of Ammonia and Nitrogen Dioxide

With the increased emissions of nitrogen oxides, atmospheric nitrate aerosols have become a great concern. The presence of total nitrate in the atmosphere is as much as 25% of the total aerosol pollutants, in which ammonium nitrate is always in equilibrium with ammonia and nitric acid. Although ammonium nitrate is a major pollutant in the atmosphere, very limited data exists on its concentrations and size distributions and mechanisms of formation. The aim of this work was to study the formation and growth of ammonium nitrate aerosols from thegas-phase reaction of nitrogen dioxide and ammonia in air, with the specific objective to identify the mechanisms of aerosol formation and growth. The N0 2-NH3 reaction was studied in a laminar flow aerosol reactor. A TSI differential Mobility Particle Sizer (DMPS), interfaced with an IBM/XT personal computer, was used to measure the size distributions in the range of 0.01-1.0 ~� The concentrations of the reactants after mixing were in the range of 0.5-14 ppm. The reaction was studied at the atmospheric pressure and in the temperature range of 4.4-21.0 �C (40-70 �F). Ammonium nitrate aerosols form by the homogeneous nucleation and grow by the condensation of the monomeric NH4No3 and to a lesser extent by the adsorption of NH3 and HN03 vapors on the particle surface followed by the surface reaction of the adsorbed species. A number distribution equation, based on the condensation equation, fits the measured data well. This indicates that the condensation of ammonium nitrate is the dominant particle growth process. The evolution of the size distributions shows that the growth by volume reaction is not possible and coagulation is not significant in the reaction conditions under study. The experime~tal critical particle diameter was found to be in the range of 0.018-0~052 ~~ The results showed an average particle diameter in the range of 0.2-0.4 pm at the reaction conditions under study. As expected the critical particle size decreased and the concentration increased when the temperature was decreased.Chemical Engineerin

Solubilities of Quinoline, Indole, Acridine, and Carbazole in Aqueous Acidic Solutions

In this research project the solubilities of four heterocyclic nitrogen compounds are measured in water, hydrochloric acid, and sulfuric acid at different temperatures. These nitrogen compounds are quinoline, indole, acridine, and carbazole. The following acidic solutions were considered: 0.02-N HCl, 0.2-N HCl, 0.02-N H2so4, and 0.2-N H2so4� The solubilities were measured at a temperature range of 20-60�C. The solubility data were used to predict the enthalpies of solutions and solubility parameters for the nitrogen compounds in water.Chemical Engineerin

Primary Papillary Serous Carcinoma of the Peritoneum: A Case of Complete Remission of Bulky Peritoneal Disease After Chemotherapy

Peritoneal papillary serous carcinoma is a rare tumor that involves the surface of the pelvic and/or abdominal peritoneum. Long-term survival among patients with this tumor has been rare. Most patients with this cancer have been treated with debulking surgery and postoperative chemotherapy. A case of incompletely resected peritoneal papillary serous carcinoma with a complete response to cisplatin-based chemotherapy is reported. Subsequent laparotomy revealed no residual tumor. This case suggests that primary chemotherapy may be successful in treating unresectable primary papillary serous tumors of the peritoneum
