Objective:  Traumatic extradural hematoma (EDH) is a common complication of head injuries, predominantly affecting the working-age male population due to increased outdoor activity. This study aimed to assess the impact of timing in surgical intervention and identify factors influencing outcomes.
Materials and Methods:  Seventy-eight consecutive patients diagnosed with traumatic EDH at Lady Reading Hospital, Peshawar, were included. Patients were categorized into two groups based on the timing of presentation: within 6 hours (early) and after 6 hours (late). Craniotomy and hematoma evacuation were performed, and outcomes were assessed at discharge.
Results:  In our study mean and SDs for age were 21.83±31.57. Most of the patients i.e., 54(69.2%) were from the 2nd and 3rd decade of life. The mean hematoma volume was 37.17 ml. The majority of the patients were males 65(83.3%) and RTA 32(42.02%) was the most common cause followed by falls and physical assault respectively. The outcome of early operated (within 6 hours) patients was favorable in 44(95.65%) while 2 (4.34%) did not improve (GOS 2,3). Favorable outcomes (GOS 4,5) in delayed presented patients who operated after 6 hours were 23 (71.87%). 5(15.6%) were not improved (GOS 2,3) and 4(12.5%) died (GOS 1).
Conclusion:  Outcomes of patients who operated early are more favorable than those who were operated late. Delayed presentation and intervention increase the mortality and morbidity of patients having traumatic extradural hematoma.

The formation of metal nanoparticles (silver, gold, platinum) by biological methods (green synthesis) has advantages over chemical and physical methods because it is easier, faster, simpler, and environmentally friendly. One of the substances used in this method is plant extracts. The presence of secondary metabolites that act as antioxidants such as phenolics and flavonoids play roles in the formation of silver nanoparticles. In this study, phytochemical screening was carried out from several herbal plants as bioreductors in the formation of silver nanoparticles, such as Phyllanthus buxifolius, Pachira aquatica, Peperomia pellucida, Ageratum conyzoides, and Piper crocatum leaf extracts. The total antioxidant content was determined using the modified phenanthroline method, and the total phenolic content determined using the Folin-Ciocalteu method. The formation of silver nanoparticles was carried out by mixing silver nitrate solution with each plant extract. Colloidal silver nanoparticles formed were then measured for their absorption spectra. The results of the antioxidant content of the five consecutive samples were 26,90 ± 0,19; 26,09 ± 0,14; 18,25 ± 0,02; 42,76 ± 0,14; dan 30,94 ± 0,14 mg AA/g, while the total phenolic contents were 48,44 ± 0,45; 21,08 ± 0,92; 17,42 ± 0,27; 57,71 ± 0,47; dan 49,83 ± 0,60 mg GA/g. Silver nanoparticles mediated by Ageratum conyzoides leaf extracts provided the highest absorbance value compared to other plants. The antioxidants and phenolic contained in the extract acts as reducing agent from silver ions into silver nanoparticles.

Published: May 2024

O presente trabalho tem por objetivo explicitar a necessidade de adoção de políticas públicas mitigadoras específicas para pessoas atingidas por barragens, no contexto do planejamento público prévio à implantação de grandes empreendimentos hidrelétricos.   A instalação de grandes usinas tem levantado uma série de questionamentos relacionados aos custos sociais e ambientais envolvidos, sobretudo pelo remanejamento populacional em decorrência das obras de instalação das usinas e o enchimento dos reservatórios.  A pesquisa, de natureza qualitativa, emprega o método etnográfico, combinando pesquisa bibliográfica, documental e entrevistas semiestruturadas.  As políticas públicas voltadas para os atingidos por barragens revelaram-se insuficientes ao longo do tempo, pois não consideram as particularidades socioculturais e econômicas desses grupos. Elas falham em oferecer suporte adequado ao processo de desestruturação-reestruturação causado pelo deslocamento compulsório e pelos impactos indiretos das barragens, como a alteração do curso dos rios, afetando a economia local.  Essas políticas oferecem soluções que apenas marginalmente atendem aos interesses dos atingidos, destacando a prevalência dos aspectos econômicos sobre os sociais na construção de usinas hidrelétricas no país.  Conclui-se que a construção de barragens no Brasil enfrenta desafios e impactos significativos, como os desastres de Mariana e Brumadinho, revelando lacunas na regulação e gestão. É urgente desenvolver políticas públicas eficazes com planejamento estratégico, abordagem equitativa e consideração dos impactos de longo prazo. Apesar das dificuldades persistentes, políticas que garantam reassentamento adequado, indenizações justas e participação das comunidades são essenciais para uma resposta eficaz e promover o desenvolvimento sustentável.

Published: May 2024

Arus globalisasi pasar bebas menyebabkan persaingan bisnis semakin kompleks. Pasar modern semakin pesat perkembangannya, seperti halnya Alfamart dan Indomart yang telah menjamur keberadaanya hingga kepolosok desa, mereka menawarkan model berbelanja secara praktis dan menyenangkan bagi konsumen, karena bidikan mereka semua lapisan masyarakat. Implikasinya pasar tradisional kalah bersaing dan semakin tidak diminati oleh masyarakat, karena dari segi sarana, pelayanan serta kualitas barangnya kalah bersaing dengan pasar modern. Akibatnya daya beli masyarakat terhadap pasar tradisional menurun tiap tahunnya. Oleh sebab itu pasar tradisional dituntut untuk bersaing dengan pasar modern. Maka perlunya pembenahan terhadap pasar tradisional di wilayah Situbondo dan diantaranya adalah pasar Sumberkolak. Peran Pemerintah Daerah sangat diperlukan dalam mengambil langkah kebijakan pengelolaan pasar. Begitu juga kreativitas pedagang dalam mengembangkan dan menjalankan usaha dagangnya. Fakta dilapangan menunjukkan bahwa pengelolaan pasar tradisional Sumberkolak di Situbondo belum menciptakan sistem pengaturan yang komprehensip dan tidak konsisten penerapannya. Sehingga berdampak pada ketidakberdayaan para pedagang akibat dari semakin kuatnyapengembangan pasar modern. Begitu pun juga pelaku pasar itu sendiri yang kura kreatif dalam menjalankan usaha bisninya.Hasil penelitian ini menyimpulkan bahwa perlu dilakukan perubahan paradigma pengelolaan pasar, dimana pasar tradisional ditempatkan sebagai investasi jangka panjang yang bertujuan untuk meningkatkan dan mendistribusikan capital bagi kesejahteraan masyarakat. Selain itu peraturan yang terkait dengan pengelolaan pasar harus ditegakkan konsisten. Oleh karena itu pembenahan pasar tradisional harusdilakukan bersama – sama, baik oleh pengelola pasar itu sendiri maupun pihak pedagang yang harus kompetitif dalam menjalankan persaingan bisnisnya.
Urban Design, Neoliberalism, and Social Control in the Context of Winnipeg's Canada Life Centre
Authors:   , Lowen Kyle
Published: May 2024

This research analyzes modes of urban social control through conventional and non-conventional policing practices in Winnipeg’s “Sports, Hospitality and Entertainment District” (SHED), and the area surrounding Winnipeg’s National Hockey League arena. This research explores the relationship between neoliberal mechanisms that drive business improvement districts (BIDs) and policing practices during events in this space. Bourdieu’s “cultural capital”, and the concept of “space and place” with an emphasis on “urban branding” give insight into cultural, social, and economic differences and contextualize how the SHED is governed to promote consumption and reduce anti-social behaviours. Using a methodology of observation and a semiotic visual analysis, the findings suggest there is an increase in police and security presences in the times leading up to, during, and after NHL games in the SHED. It is argued that policing presences contribute to a securitization of capital through assisting in upholding ‘clean and safe’ logics that typically underpin the operation of BIDs, ultimately to encourage and maintain an environment that is welcoming to consumption by the middle- to upper-class.

Authors: S Sarika. , Mary. S Anitha Janet
Published: May 2024

This paper describes a new method for maximizing power extraction from a wind energy conversion system (WECS) by using a doubly fed induction generator (DFIG) that operates below nominal wind speed. To maximize the collected power of a wind turbine (WTG) exposed to actuator failure, a fault-tolerant high-order sliding mode observer (HOSMO) and Seagull Optimization Algorithm with a model predictive controller (MPC) technique is proposed. Evaluate both the real state and the sensor error simultaneously using a higher-order sliding-mode observer. Active fault tolerant controllers are designed to regulate wind turbine rotor speed and power in the presence of actuator defects and uncertainty. With the growing interest in employing wind turbines (WTGs) as the primary generators of electrical energy, fault tolerance has been seen as essential to improving efficiency and reliability. This research focuses on optimal fault-tolerant pitch control, which is used to modify the pitch angle of wind turbine blades in the event of sensor, actuator, and system failures. A Seagull Optimization Algorithm (SOA) is proposed to tune controller parameters to improve the performance of WT. The proposed method has achieved 92% of power tracking performance when compared to existing method.

Authors: Kumar Alladi Sathish , Rajan G T Sundar
Published: May 2024

The unified power flow controller (UPFC) approach maximizes active power transfer with the least amount of losses by independently controlling both reactive and active power flow. This makes it possible to use individual transmission lines more effectively. The interline power flow controller (IPFC) utilizes the concept of UPFC for economic operation and control, management of multiline transmission systems. In its most basic form, the IPFC consists of many DC to AC converters such as voltage source inverters (VSCs), each of which performs the same purpose as the UPFC: providing series compensation for every line in multiline transmission system. A novel idea for the efficient power flow control management and compensation in multiline transmission system is the IPFC. This research proposed a backup controller for an effective modelling of IPFC in order to reduce low-frequency oscillations using four different damping controller options. The choice of an efficient damping control signal is discussed in this work in order to create a durable IPFC damping controller that can withstand changes in system loads and power supply problems. Using the proposed control approach, it is feasible to acquire both oscillation damping and independent interline power flow regulation. The results obtained in this research was improved the dynamic stability of the system using VSC based IPFC and proposed control strategy.

Authors: S Srikanth , Nayak Dr. Byamakesh
Published: May 2024

The development of bifacial photovoltaics has led to significant advancements in solar energy. Unlike traditional solar panels, which only generate electricity from the front side, these panels capture the energy from the rear and front surfaces. Bifacial photovoltaics utilize a dual-sided absorption to capture the sunlight that falls on nearby structures and the ground. This technology helps boost their efficiency and makes them an economical and sustainable choice. Furthermore, the increased energy production from the rear side of bifacial panels may lead to higher voltage fluctuations, which affects the thermal stability of PV inverter. Nevertheless, PV inverter is regarded as critical component which affects the reliability performance. Hence in this paper reliability improvement methodology with hybrid IGBT is proposed for the PV inverter. The hybrid IGBT consists of Silicon (Si) IGBT and Silicon Carbide (SiC) Schottky diode. A test case of 3-kW Monofacial and Bifacial grid connected PV inverter system with various albedos is considered. Mission profile for one year at Hyderabad, India location is logged for the assessment. B10 lifetime is calculated for the proposed hybrid IGBT. The effectiveness of the proposed hybrid IGBT is evaluated in comparison with conventional IGBT. The proposed hybrid IGBT significantly improves the reliability performance of the PV inverter.

Published: May 2024

One of the essential techniques for figuring out Power Distribution System performance is reliability evaluation. With time, the range of methods for assessing reliability has grown, and the distribution system's evolution has also become more intricate. The likelihood of a network failing grows with time once it begins to function, especially if it is used for an extended period. Reliability indices have been evaluated using different algorithms such as Particle Swarm Optimization (PSO), Genetic Algorithm (GA) and various modified versions of algorithms. The Jelly Fish Search Algorithm has been used in various power system applications such as to determine the most cost-effective way to dispatch generating units' loads, integrate Distributed Generation (DG) units, track the maximum power of photovoltaic systems, and determine optimal power flow solutions, among other uses. The performance indices for the Radial Distribution System (RDS) have not been evaluated using JFSA.Variation of performance indices with respect to unavailability has not been discussed in the literature. Here an attempt is made to analyse the variation of the indices with the unavailability. The proposed algorithm is evaluated first on 3 load point radial distribution system and the computations are performed on the popular IEEE-RBTS Bus2 test system. Based on the output it is observed that for the both the systems the behaviour of the indices with respect to the unavailability is in similar fashion. The equations are derived for the performance indices using the Minitab. With the equations obtained the Performance indices values can be predicted for the given unavailability value. It is the better appropriate method for the assessing the performance indices of Radia Distribution System.
Application of Many-Objective Arithmetic Optimization Algorithm and TOPSIS for Optimal Planning of DGS in Distribution Systems

Published: May 2024

The traditional planning of distribution networks is changing because of the accelerated expansion of distributed generation (DG) technologies in various capacities and forms. However, the improper integration of DGs in current distribution networks can give rise to several technical difficulties despite the advantages provided by distributed generation technologies. This paper presents the optimal DG planning in the distribution system using a Pareto-based many-objective arithmetic optimization algorithm (MOAOA) for optimal DG planning problems in the distribution system. This work focuses on improving four technical metrics related to distribution systems: mitigation of electrical energy not served (EENS), total voltage deviation (TVD) minimization, voltage stability index (VSI) maximization, and energy loss mitigation. Two scenarios are considered: the first scenario primarily focuses on optimal planning of DGs supporting active power only (e.g. Micro-Turbines DGs), and the second scenario focuses on optimal planning of DGs supporting both active and reactive power support (e.g. BIOMASS DGs). The optimal Pareto fronts between the competing objectives are generated using the Pareto-based MOAOA algorithm. The TOPSIS (a technique for order performance by similarity to ideal solution) multi-criteria decision-making technique is utilized for selecting the best trade-off solution from the optimal Pareto front. The posited method is examined on two standard IEEE-69 bus distribution systems. The efficacy of the MOAOA is compared with the outcomes of MOPSO, MOGWO and NSGA-II.
