Abstract Antibiotic toxicity and multi drug resistant pathogens are the two greatest challenges being faced by today's medical world. In the present study, the antimicrobial activity of spices has been investigated as an alternative to antibiotics in order to tackle these dangers. In search of bioactive compound, methanol and acetone extract of 5 Indian spices were screened for antibacterial property. The choice of spice as an alternative is based on two basic reasons: firstly, plants have been the model source of medicine since ancient times and secondly, the increasing acceptance of herbal medicines by general population methanolic and acetone extracts were used to determine antifungal properties of the spices. The antifungal activity of five common Indian spices namely clove, ajwain, turmeric, dalchini and black pepper against two bacteria Aspergillus niger and Trichoderma sp. The results revealed that the methanol extracts of spices (MIC values of 20- 100 μl/ml) have high antimicrobial activities on all test organisms (range of inhibition, 6- 16 mm) as compare to acetone extracts of spices in same concentration. Results concluded that these spices contain high amount of secondary metabolites due to these metabolites they have high antimicrobial activity and it can be used as good bio- preservater and it can also use for medicinal purpose. Keywords: Antibacterial Properties, Secondary Metabolites, Multi Drug Resistant Pathogens.
While an EMAT (Electro Magnetic Acoustic Transducer) in its simplest form is comprised of a magnet and an RF coil used to generate sound by electromagnetic induction in materials it is actually a rather complex system where each part of the sensor and instrumentation needs careful optimization for application specific performance. Historically EMAT inspection has suffered in widespread use because of a fundamental problem with the technology which is transducer inefficiency. EMAT requires very high power and very precise electronic designs to generate and
detect the signals.
Laser communications offer a viable alternative to RF communications for inter satellite links and other applications where high-performance links are a necessity.

An electric circuits' remote switching system based on gsm radio networkeSAT Journals
Abstract Mobile phone industry is classified among the fastest growing engineering branches. It has to be exploited for vast applications, reliability and affordability. Mobile cellular phone subscribers have reached saturation point; with such information, the basic cell phone that was mainly utilized to make calls will also be utilized for remote switching and control activities. The now developed system is based on the global system for mobile communications (GSM) radio network: it will operate as a very long distance remote switch. Utilizing the daily cell phone, a user will either put on/off any desired electric circuit located in an owned, controlled compound. Two cell phones are provided, one being a mobile transmitter user end and another being referred to as a fixed receiver end. A signal will be sent from the user end to put a consumer’s electric circuit either on or off at the receiver end; afterwards, the receiver end will notify the user-end about the on/off state of the consumer. The particularity of this publication is the system simplicity, yet cheap and safe, so that even very low income cell phone users can enjoy radio frequency (RF) technology’s increasing applications. The software utilized to develop and simulate circuits is the linear technology, LT spice. The calculative theory has quantitatively enriched the methodology. Both the building blocks and the physical implementation diagrams for the system are herein contained. The remote switching system based on GSM radio network has been successfully designed, implemented, tested and its functionality has been examined.

2008 IEEE AP-S-Internal Wideband Monopole Antenna For MIMO Access-Point Appli...Saou-Wen Su
A three-antenna MIMO system capable of generating a wide operating bandwidth of 2400-5850 MHz for access-point applications is introduced. The proposed design is based on a bent metal-plate monopole antenna with a compact size of 20 × 20 × 14 mm3. The three antennas are equally spaced along the perimeter of a circular ground and all generate a wide bandwidth of larger than 4 GHz. With the antenna short-circuiting facing the center of the ground, not only the overall antenna size is reduced but also good isolation of less than -20 dB can easily be obtained. Calculated envelope correlation is also less than 0.002 across the operating band.

A compact, printed, ultrawideband (UWB) monopole antenna suitable to be as an internal antenna attractive for future UWB applications is demonstrated. The proposed antenna is of a small form factor with the dimensions 6 mm × 33 mm and can easily be fed by 50-ohms mini-cable line. The antenna mainly comprises a monopole antenna, a feeding strip and a ground plane, all printed on a small FR4 substrate. The monopole antenna is printed on both layers of the substrate with an end portion on the back for control of the first/lower resonant mode of the antenna. The feeding strip in between the monopole antenna and the ground plane is further offset to achieve better impedance matching and proper upper-edge operating frequency. With the proposed antenna structure, which provides an operating bandwidth of larger than 2.7 GHz, the impedance bandwidth by 10-dB return loss can easily cover the 3.1–4.85 GHz band, the lower band of the UWB operation.

A Miniature RFID Antenna at UHF Band using Meander-Line Technique IJECEIAES
This paper displays a new design of a small antenna proposed for radiofrequency identification (RFID) applications in the UHF band (ultra-high frequency). Our antenna is constituted of two rectangular patches linked together with a meander line. Using this technique reduction in antenna size of equal to 62% with respect to the conventional antenna was achieved. The antenna has a simple structure and small antenna size of 60 x 74mm or 0.184 λ0 x 0.226 . It has been fabricated on a low-cost FR4 substrate and measured to validate the simulation performances. The measured bandwidth is around 54.4 MHz (889.3 - 943.7 MHz) with reflection coefficient less than 10 dB, which covers all of the American RFID band (902 - 928 MHz), Chinese RFID band (920.5 - 924.5 MHz), Korea Republic and Japan RFID band ( 917 - 923.5 MHz). The design and simulations have been effected by electromagnetic simulators HFSS and CST microwave studio. A good accord is getting between the simulated and measured results. This antenna is intended for the reader of RFID applications. λ0 2

Ultra low phase noise and high output power monolithic microwave integrated ...IJECEIAES
A novel structure of low phase noise and high output power monolithic microwave integrated circuit (MMIC) oscillator is presented in order to use it in 5G applications. The oscillator is based on the ED02AH process which allows us to design a microwave oscillator keeping a minimum size which is impossible to have it using other technologies since microwave oscillators are sensitive components above 20 GHz. The oscillator is studied, designed, and optimized on a GaAs substrate from the OMMIC foundry using the advanced design system (ADS) simulator in order to obtain a miniaturized oscillator (1.1×1.3 mm2 ) generating two signals of different frequencies fo1=26 GHz and fo2=30 GHz. The objective is to design an oscillator with high output power and low phase noise while respecting its specifications. The optimization of the proposed microwave oscillator shows satisfying results. Indeed, at 26 GHz and 30 GHz, the output powers are respectively 13.33 dBm and 14.89 dBm. The oscillator produces a sinusoidal signal of 1.5 V and 1.75 V amplitude respectively at 26 GHz and 30 GHz. The oscillator phase noise at fo1 and fo2 resonance frequencies using the liquid crystal (LC) resonator shows respectively -109 dBc/Hz and -110 dBc/Hz at 10 MHz offset.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
