No full textLocal instillation of antibiotics has been shown to lead to faster
healing in many deep-seated abscesses. A prospective controlled
clinical study was carried out in 27 patients with breast abscesses to
evaluate the effect on healing of local instillation of antibiotic into
the cavity of breast abscess. In the control group (n=13), ten patients
were managed by needle aspirations and three underwent incision and
drainage of the abscess cavity. These patients received oral
antibiotics. In the study group (n=14), ten patients were managed
needle aspirations and four underwent incision and drainage. These
patients, besides oral antibiotics also received antibiotics locally by
instillation of injection Cloxacillin into the abscess cavity. Patients
in the study group managed by needle aspiration had a significant
reduction in healing time (5.4 days compared to 10.5 in control group,
p < 0.05) as well the number of aspirations (1.8 compared to 3.4 in
control group, p< 0.05). A significant reduction in healing time was
also seen, when recovery time of patients in the study group managed by
open drainage (5.7 days) was compared to patients in control group
(17.6 days, p<0.05). None of the patients developed any complication
as a result of the application of antibiotics. From this study, it can
be concluded that local instillation of antibiotics besides systemic
administration is safe and results in faster healing of breast
abscesses

Leadership The Essence of Sikhism
No full textThe Sikh religion being the most modern and scientific religion is unique as far as its content, philosophy and fait are concerned. It is a general believe that faith and logic cannot go hand in hand, but Sikh religion as such has no threat from science, rationality, logics and objectivity. This religion has evolved many leaders who showed their inbuilt leadership styles in their own ways, right from the time of its evolution. Much of literature till now has showed the compatibility between Sikh religion and leadership values. This research paper highlights some common characters of a Sikh, as mentioned in Guru Granth Sahib Ji, with that of an ideal leader. The main aim of the study is to explore how Guru Prophets and the Sikh followers showed their strength, courage and leadership qualities for the community and set an example for others. An attempt has also been made to give a message to the Sikhs to imbibe in them the fading away Guru's message for the transformation of the community as a whole.

Perceived Parental Encouragement and Self-Concept in Relation to Adjustment in Adolescents
No full textParental encouragement, self concept and adjustment are important aspects of
adolescent are life and are related with each other. Present study researched up on the
contribution of parental encouragement and self concept towards the adjustment of
adolescents. 184 adolescents in the age range of 16 to 18 were tested on Parental
Encouragement Scale, Adjustment Inventory, and the Self disclosure scale. Analysis
of the result revealed that parental encouragement is related to emotional adjustment
(r= -.29**, p < 0.01) and have a positive correlation with overall self concept of the
adolescents (r=.26**, p < 0.01). Self- Concept was found to have a negative
correlation with overall adjustment ( r= -.36**, p < 0.01) with emotional adjustment
(r= -.35**, p < 0.01) with social adjustment problems ( r=-.28**, p < 0.01) and
educational adjustment problems (r-.16*=p < 0.05). The self concept is negatively
related to adjustment because higher score indicates adjustment problems, thus the
correlation is negative. Adolescent with Low self concept had more difficulties with
adjustment than those who had high self concept. Similarly adolescent who perceived
low parental encouragement had adjustment problems
Design and Development of Fractal Aperture Coupled Microstsrip Patch Antenna for Wireless Applications
No full textThe wireless industry has undergone a volatile emergence today in present era. Antenna the most important component of wireless system demand versatility and unobtrusiveness. Need of multiband antennas are increasing day by day due to need of covering maxinum applications. Fractal plays a prominent role for these requirements. Fractals have non-integral dimensions and their space filling capability could be used for miniaturing antenna size and their properties of self similarity in the geometry leads to have antennas which has more number of resonant frequencies. Fractal geometries when applied to UWB generator patch, improves gain, return loss and radiation characteristics. Often fractal antennas does not require any matching components to achieve multiband or broadband performance. Thus the research work presented here in thesis focuses on the design and simulation of a plus shped carpet fractal antenna, koch aperture coupled fractal antenna, complementary bowtie aperture coupled antenna and a cup shaped microstrip line fed antenna using CST(Computer Simulation software) microwave studio version 2014. The antennas are fed using aperture coupled feeding mechanism because it provides reasonably higher bandwidth as compared to other feeds and a moderate amount of spurious radiations A plus shaped carpet fractal antenna covers the frequency band ranging from 3.9-4.08 GHz, 4.8-5.06 GHz, 6.1-6.4 GHz, 6.93-11.39 GHz with adequate bandwidth of 180 MHz, 260 MHz, 300 MHz and 4460 MHz respectively. Koch fractal aperture coupled antenna covers the frequency band ranging from 5.3-9.2 GHz with adequate bandwidth of 3900 MHz resonating at 6.9 GHz, 8.0 GHz and 8.4 GHz respectively. Complementary bowtie antenna covers frequency range from 4.08-6.2 GHz with impedance bandwidth of 2120 MHz. A cup shaped fractal antenna covers the frequency range from 4.9-25.9 GHz with bandwidth of 21 GHz. In order to verify the antenna application in the practical scenario, plus shaped carpet fractal and bowtie aperture coupled antennas are fabricated using photolithography process and tested on a VNA and measured results are quite matching with simulated ones allowing the antenna to be suitable for WLAN, WiMAX, WIBAN, HIPERLAN, UWB, radio communication, satellite communication, radar communication applications
MIMO Antenna Design for 5G Applications
No full textPhD Thesis_12-10-2023The emergence of fifth-generation wireless communication has brought significant advancements in technology, data rates, size, and overall system performance. To fully leverage the capabilities of 5G networks, accommodating multiple communication technologies within limited space has become an increasingly significant challenge. Today's modern gadgets and devices are compact yet versatile, serving as multimedia systems that support a wide range of applications, including virtual reality, high-end online gaming, and multi-person video calling. With the growing complexity of these advanced applications, higher data rates are needed, necessitating greater bandwidth from the communication technology being employed.
In order to fully exploit the capabilities of 5G networks, efficient and robust antenna systems are essential. This thesis focuses on the design and optimization of antennas specifically tailored for sub-6GHz 5G applications, aiming to enhance coverage and capacity in 5G wireless networks. The initial phase of this research involves a comprehensive review of the unique requirements and challenges associated with sub-6GHz 5G frequency bands. Factors such as spectrum allocation, performance parameter and diversity parameter of MIMO antenna are analyzed to gain a deeper understanding of the design considerations for antennas operating in this frequency range. Based on the insights gained from the analysis a novel antenna design methodology is proposed in thesis. The methodology incorporates, optimization algorithms, design, analysis and testing of proposed antennas. Key antenna parameters, including impedance matching, bandwidth, gain, radiation patterns and isolation between antenna elements are carefully considered to ensure optimal performance in terms of coverage, capacity, and quality of service. In the present work, we started with a single element antenna design and then extended it for dual/multiple element antenna designs for 5G applications.
In the first antenna design, we designed and optimized a single element microstrip patch antenna for 3.4-3.8 GHz band of 5G.The optimization of geometrical parameters has been done using evolutionary optimization techniques. In particular, we optimized the geometrical parameters using Particle Swarm Optimization, Bat algorithm, Differential Evolution, and Artificial Bee Colony algorithm. The final optimized antenna resonates at 3.6 GHz with a measured -10dB bandwidth of 400 MHz, 4.78 dBi gain and radiation efficiency of 74%.Thesepromising results allow the proposed antenna is suitable to be employed in 5G wireless applications such as wireless routers, tablet devices etc.
In the second antenna design, we further extended our work on designing a compact dual-element MIMO antenna with dual-band characteristics for GSM-900 (0.88-1.08 GHz) and sub-6 GHz 5G band (3.11-4.63 GHz).However, when both elements of the antenna are placed on a single substrate, poor isolation of the MIMO antenna occurs, necessitating decoupling structures for improved isolation, which increases the antenna's complexity. As a solution, we have developed a MIMO antenna with a self-isolation of 19dB, reducing the need for extra decoupling circuits. The most important feature of this proposed antenna is that it is able to achieve high isolation (19 dB) and broad bandwidth (1.52 GHz) for 5G applications simultaneously without employing external decoupling structures.
For third antenna design, we have designed quad-element antenna for practical application of 5G. Portable devices like smart-phones and tablets, as well as on body and automotive applications of 5G, require multiple antenna elements to enable high-speed data transfer and reduce signal interference. These antennas work together to provide a stronger and more stable connection, improving the overall performance of the device. The designed antenna exhibits a high peak gain of 6dB along with satisfactory diversity results. The proposed MIMO antenna also exhibits good performance in different practical scenarios such as on-body(phantom), integration of antenna in housing and on-vehicle roof for automotive application.
In summary, three antenna designs are demonstrated single-band, dual and wide band operations within sub-6 GHz applications of 5G. The objectives of the research work to achieve compact size, enhanced gain and high isolation of multiple input multiple output antenna has been successfully accomplished. All the designed antennas underwent simulation using CST microwave studio suite to assess their performance. Subsequently, antenna structures were fabricated and experimentally tested for the validation of results. The s-parameters of designs were measured using a Vector Network Analyzer (VNA) available in the Microwave and Antenna Research Laboratory of Thapar Institute of Engineering and Technology (TIET), Patiala. The radiation patterns of all designs were measured in anechoic chamber, which is available in Indian Institute of Technology (IIT), Roorkee
Power Quality Standards, Problems and their Solutions
No full textRecently, power quality has become an important subject and area of research because of its increasing awareness and impacts on the consumers, manufacturers, and utilities. There are a number of economic and reliability issues for satisfactory operation of electrical equipment. As power quality problems are increasing manifold due to the use of solid state controllers, which cannot be dispensed due to many financial benefits, energy conservation, and other production benefits, the research and development in mitigation techniques for power quality problems is also becoming relevant and important to limit the pollution of the supply system. In such a situation, it is quite important to study the causes, effects, and mitigation techniques for power quality problems. In this paper different power quality standards like standards such as IEEE 519 1992, IEC 61000, and many others in different countries have been developed on the permissible limits in the levels of deviations and distortions in various electrical quantities such as voltage, current, and power factor are being discussed. Further power quality problems and their possible solutions are also discussed.

Next generation insect pest control in cotton: Current status, challenges and future perspectives
No full textInsect pests pose a serious threat to cotton cultivation across the globe. The current pest management methods, which include the transgenic methods to combat the insect pests have limitations and are not entirely effective. However, CRISPR/CRISPR-associated gene (Cas) systems and RNA interference (RNAi) based non-transgenic approaches are potent technologies that can effectively control the insect pests of cotton. RNAi enables the ability to silence key genes in insects, resulting in the selective destruction of the target species when double-stranded RNA (dsRNA) is introduced into cells and causes the complementary messenger RNA to be inactivated in a sequence-specific way. On the other hand, CRISPRCas is a genome editing technique that picks out a particular DNA section, makes a clean cut at the target site, and either renders a gene dysfunctional or replaces one gene version with another. Currently, ineffective and highly variable outcomes when various insect species, strains, developmental stages, tissues, and genes are targeted prevent the wide adoption of RNAi and CRISPR/CRISPR-associated gene (Cas) based pest control methods. The primary technological obstacle for the successful implementation of RNAi is RNAi efficiency. Double-stranded ribonucleases (dsRNases), endosomal entrapment, insufficient operation of the core machinery, and insufficient immune stimulation contributes to the low efficiency of RNA
