Diseases of the kidney and urinary tract including urolithiasis became a major cause of global illness and death. There are approximately 7.85 million people suffering from chronic renal failure in India. Further, urolithiasis is also a common global phenomenon of renal disorders. Unani Medicine (UM) is a famous kind of conventional medicine practised throughout South Asia that relies on the ancient conventional medicinal systems of India, Egypt, China, Iraq, Syria, and Persia. Berberis vulgaris (BV), Physalis alkekengi (PA) and Boswellia serrata (BS) are very common drugs against urinary disorders in Unani medicine. But, to establish their role to treat in urinary disorders are still obscure. HPTLC fingerprints confirmed the presence of signature compounds according to pharmacopeia. Polyphenolic acids and flavonoids in the test drugs have been quantified by HPLC. BS showed maximum inhibitory action on DPPH (2,2-diphenyl-1-picrylhydrazyl) radicals, nitric oxide and superoxide scavenging than other two test drugs, while, PA have highest hydrogen peroxide scavenging action. In diuretic activity, maximum urination occurred in BS group than other two test drugs BV and PA. The highest excretion of sodium–potassium ratio was noted in PA groups followed by BS and BV. BV showed maximum efficacy in crystal formation in test tubes followed by BS and PA.

BEL1-like transcription factors interact with Knotted1 types to regulate numerous developmental processes. In potato (Solanum tuberosum), the BEL1 transcription factor St BEL5 and its protein partner POTH1 regulate tuber formation by mediating hormone levels in the stolon tip. The accumulation of St BEL5 RNA increases in response to short-day photoperiods, inductive for tuber formation. RNA detection methods and heterografting experiments demonstrate that BEL5 transcripts are present in phloem cells and move across a graft union to localize in stolon tips, the site of tuber induction. This movement of RNA to stolon tips is correlated with enhanced tuber production. Overexpression of BEL5 transcripts that include the untranslated sequences of the BEL5 transcript endows transgenic lines with the capacity to overcome the inhibitory effects of long days on tuber formation. Addition of the untranslated regions leads to preferential accumulation of the BEL5 RNA in stolon tips under short-day conditions. Using a leaf-specific promoter, the movement of BEL5 RNA to stolon tips was facilitated by a short-day photoperiod, and this movement was correlated with enhanced tuber production. These results implicate the transcripts of St BEL5 in a long-distance signaling pathway that are delivered to the target organ via the phloem stream.

Asavas and arishtas are considered as important Ayurvedic self-fermented dosage forms which are being used widely to promote health and well-being and for management of digestive and metabolic disorders. The present investigation was carried out to study the potential of an Ayurvedic polyherbal asava–arishta preparation (ZP) in gastroprotection, intestinal motility and gastric dyspepsia in experimental rodent models. The gastroprotective effect of ZP at doses 1.5, 3 and 6 ml/ kg of body weight was studied using battery of animal models such as pyloric ligation in rats, intestinal transit time using charcoal meal test, gastric emptying and digestive stimulation action in rats. In addition, anti-spasmodic activity was studied using isolated guinea pig’s ileum. The role digestive enzymes such as pepsin, α-amylase and lipase were accessed by various enzymatic assays. A dose-dependent and statistically significant (p < 0.01) inhibitory effect on reducing gastric volume, free acidity, total acidity and ulcer index were observed in ZP treated animals as compared to the control. ZP also enhanced the mucin content of the gastric juice. Pre-treatment with ZP produced a dose-dependent effect in reducing intestinal motility, intestinal spasms and increased the gastric emptying time in rats. These observations validated the age old claims of ZP for its use as digestive tonic. Thus, results concluded that ZP is having potential to improve digestion and reduces recurrent digestive ailments.
Seismic response estimation of steel plate shear walls using nonlinear static methods
Anjan K. Bhowmick,Moon Moon Dhar 국제구조공학회 2016 Steel and Composite Structures, An International J Vol.20 No.4
One of the major components for performance based seismic design is accurate estimation of critical seismic demand parameters. While nonlinear seismic analysis is the most appropriate analysis method for estimation of seismic demand parameters, this method is very time consuming and complex. Single mode pushover analysis method, N2 method and multi-mode pushover analysis method, modal pushover analysis (MPA) are two nonlinear static methods that have recently been used for seismic performance evaluation of few lateral load-resisting systems. This paper further investigates the applicability of N2 and MPA methods for estimating the seismic demands of ductile unstiffened steel plate shear walls (SPSWs). Three different unstiffened SPSWs (4-, 8-, and 15-storey) designed according to capacity design approach were analysed under artificial and real ground motions for Vancouver. A comparison of seismic response quantities such as, height-wise distribution of floor displacements, storey drifts estimated using N2 and MPA methods with more accurate nonlinear seismic analysis indicates that both N2 and MPA procedures can reasonably estimates the peak top displacements for low-rise SPSW buildings. In addition, MPA procedure provides better predictions of inter-storey drifts for taller SPSW. The MPA procedure has been extended to provide better estimate of base shear of SPSW.
Object Classification for Video Surveillance System
Anjan Kumar Paul,Jae-Hong Min,Mohammad Khairul Islam,Young -Bum Kim,Joong Hwan Baek 대한전자공학회 2010 ICEIC:International Conference on Electronics, Inf Vol.1 No.1
Object classification has major applications in image retrieval, video summary generation, video surveillance etc. Video surveillance system possesses an important role in the field of security. Video surveillance is a major application where object classification having a vital role. The major drawback of current video surveillance system is that can not prevent intrusion without human interactions. Most of them are semi automated and decision making task mostly depend upon human interactions. Existing systems also deal with the single class, mostly with human class. Classification and recognition of left behind objects is very important for smart video surveillance system. We have developed a smart object classification module for current video surveillance system where we adopted the concept of bag of words. The total work we have finished in two major steps, training which is accomplished in offline, testing is finished at online with still image. We test with four different classes of dataset dividing them into test and training samples and our overall performance is good.

Solar cell devices are one of the most promising technologies for generating green energy. Forefront perovskite-based solar cells have increased worldwide hope for solving global warming issues. Tight bandgap formamidinium lead iodide (TBFAPbI 3 ) perovskite as an active layer to absorb sunlight along with a desired electron transport layer (ETL) can produce effi cient and stable perovskite solar cells (PSCs). Here, TB-FAPbI 3 with tin oxide (SnO 2 ) as an ETL was employed to fabricate PSCs. These PSCs recorded a low champion effi ciency of 18.35%. A cobalt-doped SnO 2 layer was designed to increase the effi ciency of TB-FAPbI 3 solar cells. The modifi ed SnO 2 boosted the solar cell effi ciency to 20.10% due to the improved conductivity of the ETL and increased charge transfer phenomena in the PSCs. From one side, electron transfer is facilitated at the ETL/perovskite interface. On another side, the reduced surface defects on the fabricated perovskite layer over the modifi ed ETL diminish charge traps in the solar cell. In addition, cobalt doping does not hinder the light transmission from the SnO 2 into the perovskite layer. The modifi ed SnO 2 assists in the formation of a more compact TB-FAPbI 3 layer and promotes the stability properties of PSCs.
ON NOETHERIAN PSEUDO-PRIME SPECTRUM OF A TOPOLOGICAL LE-MODULE
Anjan Kumar Bhuniya,Manas Kumbhakar Korean Mathematical Society 2023 대한수학회논문집 Vol.38 No.1
An le-module M over a commutative ring R is a complete lattice ordered additive monoid (M, ⩽, +) having the greatest element e together with a module like action of R. This article characterizes the le-modules <sub>R</sub>M such that the pseudo-prime spectrum X<sub>M</sub> endowed with the Zariski topology is a Noetherian topological space. If the ring R is Noetherian and the pseudo-prime radical of every submodule elements of <sub>R</sub>M coincides with its Zariski radical, then X<sub>M</sub> is a Noetherian topological space. Also we prove that if R is Noetherian and for every submodule element n of M there is an ideal I of R such that V (n) = V (Ie), then the topological space X<sub>M</sub> is spectral.
