  • The Unani System of Medicine (USM) is one of the traditional systems of medicine that deals with plants. Plants are large source of medicine. JIRJEER (Eruca sativa) is one of the plant origin drugs, has been used for various therapeutic purposes in USM. It contains Erucic acid (major contain), oleic acid, linoleic acid, saturated Fatty acids, Flavonoids, Phenolics, Glucosinolate, Vitamin C and Carotenoids. These active constituents are responsible for their actions described in Unani classical literature such as Muqqawwi-e-bah (Aphrodisiac), Muwallid-e-mani (Spermatomatogenic), Daf-e-sumoom (Antidote), Kasir-e-riyah (Carminative), Jaali (Cleanser/Detergent), Mudirr-e-bawl (Diuretic) wo Mudirr-e-hayd (Emmenogoggue), Muhammir (Rubefacient), Hazim (Digestive), Mulaiyan (Laxative), Muzliq-e-mani (Lubricant), Muddir-e-shir (Galactopoietic), Mufattih-e-Sudad (Deobstruent), Musakhin (Analgesic), Mulattif (Demulcent), Mufattit-i-hasah (Lithotriptic) and whole plant is considered as aphrodisiac. This is a review paper which discusses morphology, pharmacological action, ethno-medicinal and therapeutic uses of this medicinal plant in perspective of Unani medicine. This review has been done through online searches of databases such as PubMed, Google Scholar, Embase, science direct and hand search for classical textbook available in different libraries. It concluded that JIRJEER (Eruca sativa) is one of the best herbal medicines in treatment of Antiulcer, Antibacterial, Fertility, Hepato-protective, Hyperlipidemic, Antioxidant, Antihypertensive, Anti-inflammatory and Anti-edema, Nephro-protective, Antidiabetic, Antifungal and Anticancer properties.

  • Novel power system stabilizers (PSSs) have been proposed to effectively dampen low frequency oscillations (LFOs) in multi-machine power systems and have attracted increasing research interest in recent years. Due to this attention, recently, fractional order controllers (FOCs) have found new applications in power system stability issues. Here, a tilt-integral-derivative power system stabilizer (TID-PSS) is proposed to enhance the dynamic stability of a multi-machine power system by providing additional damping to the LFOs. The TID is an extended version of the classical proportional-integral-derivative (PID) applying fractional calculus. The design of the proposed three-parameter tunable TID-PSS is systematized as a nonlinear time domain optimization problem in which the tunable parameters are adjusted concurrently using a modified group search optimization (MGSO) algorithm. An integral of the time multiplied squared error (ITSE) performance index is considered as the objective function. The proposed stabilizer is simulated in the MATLAB/SIMULINK environment using the FOMCON toolbox and the dynamic performance is evaluated on a 3-machine 6-bus power system. The TID-PSS is compared with both classical PID-PSS (PID-PSS) and conventional PSS (CPSS) using eigenvalue analysis and time domain simulations. Sensitivity analyses are performed to assess the robustness of the proposed controller against large changes in system loading conditions and parameters. The results indicate that the proposed TID-PSS provides the better dynamic performance and robustness compared with the PID-PSS and CPSS.

  • The fast emerging of network technology and the high demand of computing resources have prompted many organizations to outsource their storage and computing needs. Cloud based storage services such as Microsoft's Azure and Amazon's S3 allow customers to store and retrieve any amount of data, at anytime from anywhere via internet. The scalable and dynamic of the cloud storage services help their customer to reduce IT administration and maintenance costs. No doubt, cloud based storage services brought a lot of benefits to its customer by significantly reducing cost through optimization increased operating and economic efficiencies. However without appropriate security and privacy solution in place, it could become major issues to the organization. As data get produced, transferred and stored at off premise and multi tenant cloud based storage, it becomes vulnerable to unauthorized disclosure and unauthorized modification. An attacker able to change or modify data while data inflight or when data is stored on disk, so it is very important to secure data during its entire life-cycle. The traditional cryptography primitives for the purpose of data security protection cannot be directly adopted due to user's lose control of data under off premises cloud server. Secondly cloud based storage is not just a third party data warehouse, the data stored in cloud are frequently update by the users and lastly cloud computing is running in a simultaneous, cooperated and distributed manner. In our proposed mechanism we protect the integrity, authentication and confidentiality of cloud based data with the encrypt- then-upload concept. We modified and applied proxy re-encryption protocol in our proposed scheme. The whole process does not reveal the clear data to any third party including the cloud provider at any stage, this helps to make sure only the authorized user who own corresponding token able to access the data as well as preventing data from being shared without any permission from data owner. Besides, preventing the cloud storage providers from unauthorized access and making illegal authorization to access the data, our scheme also protect the data integrity by using hash function.

  • Pseudomonas nitroreducens TX1는 대만의 벼를 재배하는 논의 배수구에서 분리된 세균이다. 이 균주는 알킬페놀 폴리에톡실레이트와 같은 비이온성 계면활성제를 고농도에서도 탄소원으로 이용할 수 있다. 본 연구에서는 TX1 균주에서 분리된 새로운 플라스미드 pTX1의 특성을 조사하였다. 크기는 2,286 bp, GC 함량은 63.3%, 암호된 유전자로는 $Rep_{pTX1}$과 기능이 밝혀지지 않은 ORF1과 ORF2가 동정되었다. $Rep_{pTX1}$은 롤링-서클 기작에 의해 복제되는 그람 양성 세균에서 주로 발견되는 pC194/pUB110 플라스미드 계열에 속하는 DNA 복제 효소임을 알 수 있었다. 또한 세포마다 약 150개의 플라스미드가 존재함을 규명하였다. 플라스미드에 존재하는 유전자 지문과 유사 플라스미드와의 핵산과 아미노산 서열비교를 통해 pTX1은 슈도모나스 세균에서는 흔히 발견되지 않는 롤링-서클 기작에 의해 복제된다는 것을 확인할 수 있었다.
