Authors: Sandoval Urrutia Briseida Yuleni
Published: October 2022

OBJETIVO: establecer la ausencia en que incurre la organización de la Policía Nacional Civil, al exponer de oficio a los sindicados frente a los medios de comunicación social.  MÉTODO: mediante la lectura e averiguación de diversos libros sobre la autoría mediata en el Código Penal guatemalteco como de las reglas jurídicas guatemaltecas. RESULTADOS:  los medios de comunicación social al instante de que ellos toman la noticia y la ponen a disposición frente a la sociedad perjudicando de enorme forma la moral del individuo a quien en aquel instante sólo se le imputa un delito. La inocencia de dicha persona queda deshonrada ya que la sociedad se comienza a referir al sujeto como el responsable, aunque no se le demostró lo opuesto y un juez competente no ha proclamado o resuelto una condena hacia el individuo. CONCLUSIÓN: para lograr deducir la responsabilidad de una persona, se necesita que se haga un proceso penal completo, a partir de la aprehensión hasta el pronunciamiento de la sentencia, para no vulnerar su presunción de inocencia, el honor, intimidad e imagen del sindicado. La Constitución Política de la República de Guatemala, el Código Procesal Penal y la Ley Orgánica de la Policía Nacional Civil, contemplan la regulación mínima deben tratar a los detenidos.
TRANSFORMACIJA IZ DRUŠTVA SA OGRANIČENOM ODGOVORNOŠĆU U OTVORENO AKCIONARSKO DRUŠTVO

The Company Law of the Republic of Srpska envisages four forms of companies: partnerships, limited partnerships, limited liability companies and joint stock companies, and in practice the last two forms of companies are most common. Although before, now more than ten years ago, the stock exchanges in Bosnia and Herzegovina had a large turnover by trading in the shares of listed joint stock companies, today this is not the rule, but the exception. Having mentioned this exception, I cannot but mention another circumstance that can be considered the same, and that is the change of legal form from a limited liability company to a joint stock company, which is the topic of this text. The only recorded case of such a transformation of the legal form in Bosnia and Herzegovina is the transformation carried out by the limited liability company „Fratelo trade“ from Banja Luka in 2008, transforming into an open joint stock company through the initial public offering (IPO) procedure. The initial public offering or „opening“ or „going public“ appears as a logical step after limited liability companies reach the maximum development in this legal form. Opening allows them to more easily raise funds for further development and improvement of business. Despite the above, this type of business transformation has not yet taken root in our country, although it has been current in the world since the 1990s, and the increase in the number of delisted joint stock companies does not inspire hope that it will happen soon. The reason for writing on this topic is an attempt to point to the IPO as an opportunity to finance further development of companies that can lead to an increase in the number of investors interested in investing in companies that decide to „go public“, which can ultimately contribute market development.

Maternal deprivation during the early neonatal period is linked to many neurodevelopmental disorders. This study was designed to investigate the protective action of vitamin B complex (Vit Bco) on maternal deprivation-induced cerebellar damage in Wistar rats. Pups were divided into four groups: control, which received 50 ml/kg of normal saline from postnatal day (PND) 21-35; Second group received 40 mg/kg of Vit Bco orally from PND 21-35; Third and fourth groups were maternally deprived for 24 h on PND 9, but the fourth group received Vit Bco in addition from PND 21-35. The pups were sacrificed on PND 36 and the cerebellar tissues were harvested and processed for histological and immunohistochemical studies, as well as oxidative status using enzymatic markers (superoxide dismutase and catalase). Cerebellar microarchitecture of maternally deprived pups revealed disruption of cortical layers, pyknotic Purkinje cells and activated astrocytes. Superoxide dismutase and catalase activities were significantly reduced in maternally deprived pups when compared with the control and the Vit Bco alone group. Pups that received Vit Bco after maternal deprivation had well-delineated cortical layout, moderately stained Purkinje cells and non-activated astrocytes, while the oxidative enzymes activities were increased compared with pups that did not receive Vit Bco intervention. Conclusively, Vit Bco ameliorates cerebellar histomorphological, neurochemical and oxidative alterations associated with maternal deprivation.

Published: October 2022

Objectives: The objectives of the study were to evaluate the vascular and tissue response of Pakistani manufactured novel drug eluting stent (called N-DEAVOUR®) on a swine model and compare the results with XIENCE PRO™.
Methodology: A total of 10 animals were used for the study and assigned randomly to each time-point group. The test articles were administered percutaneously and each animal was implanted with one stent in each one of the coronary arteries (3 in total) LCA (left circumflex artery), LAD (left anterior descending coronary artery), and RCA (right coronary artery). Additionally, a second test stent was implanted in some animals (4 in total). QCA (Quantitative Coronary Angiography) technique was used for measurements of the vessel at the target site.  OCT (Optical Coherence Tomography) was performed only at follow up time-points which were 30, 90 and 180 days.
Results: At 30 DFU, parameters for N-DEAVOUR® were comparable to those of both control (XIENCE PROTM and VISION) stents. At 90 days follow-up N-DEAVOUR® showed no statistically significant difference in performance for values of lumen area, stent area, area stenosis, and neointimal area against XIENCE PRO™. With reference to stent area, at 90 DFU, N-DEAVOUR® performed better than XIENCE PRO™ (p=0.0056). For neo-intimal area, area stenosis and lumen area, the differences between XIENCE PRO™ and N-DEAVOUR® were non-significant (p=0.13; p=0.9; p=0.086) respectively. These results indicate the positive potential of N-DEAVOUR® to be successfully implanted in clinical settings after necessary randomized clinical trials are executed.
Conclusion: This study proved that the drug eluting stent examined in the present study is both safe and feasible. This study supports that this stent can move forward for human trials.

Objectives: Active lifestyle is mandatory for prevention of atherosclerotic cardiovascular diseases. The present study was aimed to identify the physical activity of doctors as well as their knowledge and attitude toward the American College of Cardiology (ACC) recommended physical activity.
Methodology: For this survey, an online questionnaire was shared with doctors of various specialties working in private and public healthcare hospitals of Pakistan. Opinion was recorded regarding importance of physical activity (5-point scale), perceived physical activity level (4-point scale), knowledge regarding ACC recommended physical activity level, lifestyle, and barriers in following recommended physical activity level.
Results: A total of 159 doctors participated in the survey, of which 97 (61%) were cardiologists. Most participants (72.3%) were males and mean age was 32.12±4.33 years. Nearly two-thirds (61.6%) of the participants were free of any pre-existing co-morbid condition. Most common atherosclerotic cardiovascular disease risk factor was positive family history (26.4%). A total of 74.8% (119) of the participants claimed to know about ACC recommended physical activity level. According to the lifestyle activities, only 26.4% (42) of the participants were found to follow the ACC recommendations. Lack of time from daily routine (71.7%) was found to be most commonly stated reason for physical inactiveness.
Conclusion: Knowledge and adherence to the ACC recommended physical actively level is poor among both cardiologists and non-cardiologists. More than half of health care physician were overweight and obese. Lake of time, resources and overstressed work life of doctors are the key barriers in following recommended physical activity level.

Partition, Migration and a ‘New Class’ in Pakistan: 1947-1958
Authors: Bandyopadhyay Drona
Published: October 2022

In 1947 Pakistan was carved out of India. The creation of Pakistan had a long invisible history and short and fast paced visible history. Both these historical forces helped the separatist Muslim leadership in India to realise Pakistan. After the creation of Pakistan, the Muslim refugees went to their cherish homeland in large numbers. Most of them were socially forward and economically stable. This class helped the new state to have a strong foundational base in all the state controlled and private sectors including bureaucracy and military. But the Punjabi ethnicity native to Pakistan, which is also Muslim, started to develop a sense of despair and difference towards them, though in crucial military and bureaucracy they played an equally dominating role in tandem. This reality started to evolve in the early 1950s and up to the first military takeover in 1958. It continued thereafter, but variegated regional and ethnic issues started to begin. The ethnic fissures threatening the unity and integrity of Pakistan in the current times have deep-rooted origins in its formative years, meriting an in-depth analysis of its ethno-political history. The aim of this paper is to analyse the course of first ten years of Pakistan in order to understand its ethno-political dynamics. By looking into its history with the help of secondary sources available on Pakistan, this paper attempts to facilitate greater understanding of Pakistan as a state and thereby indicating avenues to address its strife.

Tuberous sclerosis complex (TSC) is the rare autosomal dominant neurocutaneous disorder that affects the individual by causing various benign lesions. However, in recent studies, few cases of TSC in which a novel malignancy is also observed. TSC has mutations in two suppressor genes, i.e. TSC1 & TSC2, responsible for developing a wide range of hamartomatous lesions [1]. Recent evidence suggests that the TSC genes play an important role in the pathway whose dysregulation leads to an array of epithelial malignancies. TSC 1 mutation is mainly identified in sporadic tumours of epithelial cells that indicate important phenotypic changes resulting from modulation of the hamartin expression. Here we present a case diagnosed with carcinoma gall bladder and having tuberous sclerosis complex defining the co-relation.

Odontogenic keratocyst (OKC) has always been a subject of interest for researchers and clinicians, owing to its unique pathogenesis, aggressive clinical behavior and association with syndromes. Majority of OKCs occur in the mandibular posterior region, and sporadic type of cysts have a predilection to occur in males and in patients of older age groups. The present article reports a case of sporadic OKC presenting in a relatively unusual manner, occurring in the maxillary anterior region of a young female patient. Unlike other reported cases that found OKC prior to commencement of orthodontic treatment, herein it had possibly occurred as a complication of the orthodontic treatment. The article also depicts characteristic microscopic features of OKC such as uniform parakeratinized lining with multiple infoldings, basal palisading, areas of interface separation between the lining and capsule. Disrupted lining with severe inflammatory cell infiltrate in the capsule was indicative of secondary infection

Published: September 2022

This study focuses on the assessment of the effects of leachates on groundwater quality in Igwuruta, Ikwerre Local Government Area of Rivers State, Nigeria. Ten (10) water samples comprising of five (5) leachate and five (5) borehole water samples were collected and analyzed as well as measurement of static water level (SWL). The sampling was done by using standard techniques. These analyzed parameters were compared with the World Health Organization guidelines for drinking water quality. The analyzed parameters were below the permissible limits of water quality guidelines, except for the leachate samples that were analyzed for chloride which concentrations ranges from 2850 - 3100mg/l below the 250mg/l and sulphate concentration ranges from 170.5 - 289.2mg/l below the 250mg/l. Iron concentration ranges from 3.6 - 4.7 mg/l above the permissible limits of 0.3 mg/l. The high concentrations of iron in the leachate is probably due to the dumping of metal scraps at the dumpsites, which corrodes, leaches out and infiltrates to contaminate the groundwater. The hydrochemical facies of the leachate samples corresponds to the region of saline water type (Na+ -K- Cl-- SO4 2-) as a result of the high concentration of Sodium. The static water level (SWL) of the area ranges from 2.5m to 8.7m. The water level data was determined in different boreholes in the study area. The maximum static water level in the study area occurs around BH4, at 8.4m below ground surface followed by BH2, with 6.2m below the ground surface. Values of static water level decreased in BH5 at 5.7m, BH1, 3.4m and BH3 at 2.5m. These values show shallow water levels which makes the aquifer in the area vulnerable to contamination from leachate and solid wastes. It is recommended that proper waste management practice(s) should be carried out in order to maintain a high level of environmental protection and sustainability as low as reasonably practicable.

Published: September 2022

This study was carried out to assess the impact or effect of industrial activities and refuse dump site on the quality of water used for domestic and sanitary purposes in parts of Port Harcourt metropolis, Rivers State Nigeria. The quality assessment was focused on physiochemical parameters. A total of twenty water samples were collected from twenty locations (randomly selected from industrial and refuse dump site areas) within the study area. Ten major physiochemical parameters which include: potency of hydrogen (PH), salinity, electrical conductivity, total dissolved solids (TDS), turbidity (NTU), calcium (Ca2+), magnesium (Mg2+), chloride (Cl), sulphate (SO4 2-) and nitrate (NO3 - ) were analyzed. The results obtained were compared with the standards of World Health Organization (WHO), and show that the water samples have PH values between 3.78 and 7.23 which is not within the permissible limit of WHO and thus, indicating that they are acidic and not fit for domestic purposes. Salinity values range between 0.018 and 0.202mg/L indicating that the water is fresh and good for sanitary purpose, electrical conductivity values range between 38.0 and 378.7µΩ/cm, total dissolved solid and turbidity values range from 32.7 to 263.0mg/L and 0.2 to 0.9NTU respectively which is within the limit prescribed by WHO. The concentration of nitrate and sulphate range between 0.47 and 3.00mg/L and <1.0 and 17.2mg/L respectively after analysis and are within the limit prescribed by WHO. The knowledge from this study can be applied in environmental and water management studies and hydrological activities

Published: September 2022

Many researchers have studied multiphase Induction motor drives and output of these research shows that output Torque of these motors is superior to that of normal three phase Induction motor. Limitations on the power level of semiconductor devices establish a barrier to the increase of converter ratings. In order to get rid of this limitation, multilevel converters have been developed where switches of reduced rating are used to construct high power level converters. Instead of multilevel converters, multi-phase machines are used: By dividing the handled power between multiple phases, generally more than three, high power levels can be achieved even using limited rated power electronic converters. The aim of this research is to implement novel design and development of six phase induction motor. Also control of the same motor is carried out when fed by two, three phase inverters.
Crystalline Phase Changes due to High-Speed Projectiles Impact on 304L Steel
Authors:   Mechanical Engineering Department, Embry-Riddle Aeronautical University, Prescott, AZ, USA, Slewa Muna
Published: September 2022

High yield 304L steel is well known for its employment in manufacturing. The quenched and tempered low-carbon alloy has a minimum yield strength of 40-50 ksi. Also, 304L offers good corrosion resistance and weldability. Traces of Chromium and Nickel in 304L give it the desired corrosion resistance properties. So, it is an ideal candidate for pressure vessels and the petrochemical industry applications. The physical characteristics and molecular structure of 304L steel are also well known; however, little is known about the high-velocity impact on this metal alloy’s crystalline structure and material phase changes. The effects of high-speed velocity impact on the crystalline structure and material phase changes due to impacts are studied herein experimentally. The high-speed impact on the crystalline structure’s inevitable phase change is examined, let alone the atomic reorganization resulting from the impact on the 304L steel. The effects of an impact on the crystalline structure are assessed by impacting 304L steel plates (15.4 x 15.4 x1.27 cm) with Lexan projectiles. A two-stage light gas gun accelerates these projectiles to a velocity of 6.70 km/s at the point of the impact. The impacted plates’ surfaces are prepared for the Electron Back Scatter Diffraction (EBSD) microscope inspection. Nine regions on each impacted plate area are examined and analyzed. Each part (90x90) square microns were cut off the test samples, keeping with the required surface finish standards. These regions are selected from the area immediately under the impact crater to locations not physically affected by the impact. Observations of collected EBSD images show that the predominant phase is Body-Centered Cubic (BCC); Face-Centered Cubic (FCC) and Hexagonal-Close-Packed (HCP) phases are also indexed. Since these crystalline structures are the most expected lattice formations, the samples are post-impact examined for molecular structure allocation changes. The results were then tabulated according to the region’s relative impact crater. Previous research, A36 steel results show that post-impact inspection of HCP phase chage, in iron specifically, is completely and rapidly reversible during impact. However, in this study, traces of HCP were found at some locations in all post-impact stages. This study also indicates that the BCC crystalline structure remained the dominant phase structure after impact, and it is valid with all test samples and all levels of shock loading. High pressure and the temperature quickly affect the target material at 6.70 km/sec velocity. The damage zone develops within 5 microseconds at this velocity due to impacting momentum

Background: Chronic kidney disease is a global public health important disease that is associated with life threatening outcomes including renal failure and premature mortality unless diagnosed and treated promptly. Diabetes Mellitus and hypertension are the two major causes of chronic kidney disease worldwide. This study is aimed to determine prevalence and associated factors of chronic kidney disease among diabetes mellitus and hypertensive patients at Ambo town public hospitals, Ethiopia. Methods: A cross-sectional study was conducted at Ambo University referral and general hospitals on 308 study participants. The participants were interviewed using interviewer administered questionnaire when they come for follow up at a chronic illness follow-up clinic. The patient charts were reviewed to retrieve information regarding medications, blood pressure, serum Creatinine and glucose level. A chronic kidney disease epidemiology collaboration equation was used to estimate Glomerular filtration rate from serum Creatinine. Data were analyzed SPSS version 23 for statistical analysis. Binary logistic regression analysis was used to identify factors associated with chronic kidney disease. Variables with a p-value below 0.2 at bivariable analysis were entered into the multivariable logistic regression model. Multivariable logistic regression analysis was used to examine the association between dependent and independent variables and p-value less than 0.05 was used to declare statistical significance. Results: A total of 308 diabetic and hypertensive patients were included in the study. Of which 156 (50.6%) participants were female with mean (± SD) age of 47.15 ± 12.06 years. The prevalence of chronic kidney disease (stage 3-5) was 20.5% with (95% CI: 16%-25%). Long duration of hypertension (AOR=4.89, 95% CI=1.93-12.40), elevated systolic blood pressure (>140mmHG) (AOR=3.20, 95% CI=1.36-7.51), family history (AOR=3.36, 95% CI=1.56-7.24) and age greater than 55 years (AOR=2.17, 95% CI=1.09-4.31) were factors associated with chronic kidney disease. Conclusion: The prevalence of chronic kidney disease was high. Older age, elevated SBP, long duration of hypertension and family history of kidney disease were factors associated with chronic kidney disease. A preventive plan is mandatory to reduce the disease and complications in the community

A CULTURA É O HOMEM
Authors: Melo Cecy
Published: October 2022

A investigação sobre a produção de conhecimento é perpassada por debates e tensões desde que a ciência se estabeleceu. Uma das formas mais relevantes dessa análise ocorre através da crítica feminista, onde se produz uma extensa crítica ao sujeito universal masculino, em especial nas discussões que versam sobre a constituição dos cânones. Diversas autoras demonstram que muito se perde ao entender o sujeito como universalmente masculino. No que se refere a essa discussão na Teoria Social, Georg Simmel é um dos intelectuais clássicos com uma produção fundamental sobre cultura e modernidade, mas que apresenta movimentos contraditórios ao teorizar sobre as mulheres. À vista disso, o objetivo deste artigo é analisar como se deu a reflexão de Simmel frente à “questão da mulher”. Foi observado que, para Simmel, há um monopólio masculino da cultura objetiva, visto que o autor aponta que a “natureza feminina” se opõe à cultura, o que omite as mulheres enquanto sujeitos construtores do mundo social. Ao argumentar que “o homem” produz cultura, Simmel não o faz em uma definição universal de humanidade. “O homem” na teoria simmeliana significa fundamentalmente o sujeito masculino e a “natureza feminina” não é percebida como adequada para a produção de cultura.
JOVENS PERIFÉRICOS E A POUCA IDENTIFICAÇÃO COM INSTITUIÇÕES DEMOCRÁTICAS
Authors: Souza Wagner Eduardo
Published: October 2022

Nos últimos anos, precisamente a partir de 2013, percebeu-se que os jovens da classe média e alta saíram às ruas em busca de seus direitos, no entanto, dentre esses jovens os da periferia ficaram isolados sem ter noção de seus direitos como cidadãos. O objetivo central deste trabalho é tratar sobre a questão da identificação do jovem da periferia, sobre a baixa identificação destes no cenário político do país. Propõe-se apresentar algumas reflexões a respeito do desinteresse desses jovens em relação à política do país, com uma alienação às questões que se apresentam no meio social, sem noção dos seus direitos. Procurar-se-á compreender qual mecanismo leva o jovem a se dispensar dessa maneira e não perceber os direitos que lhe cabem enquanto cidadão e a maneira de lutar por eles, através de pesquisa bibliográfica sob o ponto de vista do questionamento social. Assim construindo um paradigma em relação ao que leva o jovem da periferia a se isolar do contexto político e ficar à margem da discussão dos interesses sociais.

Authors: Sandoval Jesús , Kelly Rafael , Santibáñez Víctor
Published: September 2022

En este trabajo se presenta un tutorial sobre un método de diseño de controladores basado en el moldeo de energía más inyección de  amortiguamiento para el control de una clase de sistemas mecánicos completamente actuados y subactuados. Se proporciona un marco teórico  unificado que permite resolver diferentes objetivos de control como son:  regulación de posición y regulación de velocidad para ambas clases de sistemas y, seguimiento de trayectorias para el caso de sistemas mecánicos  completamente actuados. Además, la regulación de energía es formulada  como un nuevo objetivo de control para generar oscilaciones controladas en  ambas clases de sistemas mecánicos. En adición, se abordan algunos  criterios de diseño como compensación de fricción dinámica, exclusión de  medición de velocidad e inclusión de la dinámica de actuadores.  Finalmente, como ejemplos de aplicación, se presentan recientes resultados  publicados en la literatura sobre el diseño de controladores para robots manipuladores accionados por par, un péndulo con rueda inercial y un sistema carro-péndulo.

En la planificación de sistemas de tiempo real crí­tico es clave encontrar un plan temporal en el que las tareas pueden ejecutarse antes de que venza el plazo establecido. Para lograr este objetivo se pueden utilizar diferentes tipos de algoritmos de planificación. Además de encontrar un plan factible, muchas veces es beneficioso, de todos los planes factibles existentes, encontrar aquel que minimiza algún parámetro temporal del sistema. Existen muchos algoritmos de planificación que son capaces de encontrar una planificación correcta del conjunto de tareas. Pero no es tan común encontrar algoritmos que optimicen otros parámetros para mejorar el funcionamiento del sistemas en términos de estabilidad, consumo de potencia, etc. Los heurí­sticos existentes puede mejorar el comportamiento pero sin asegurar un resultado óptimo. En este trabajo exploramos las técnicas de planificación no convencionales basadas en programación lineal entera para resolver la planificación en sistemas mono procesador con el objetivo de minimizar el peor tiempo de respuesta y el cambio de contexto de las tareas del sistema y la asignación de tareas a procesadores en sistemas multiprocesador con el objetivo de minimizar la interferencia producida por el acceso a recursos hardware comunes.

Published: September 2022

Treatment of the contaminated aqueous solutions to improve their quality is indispensible for their reuse resulting in an emergent challenge to develop facile, nontoxic and less energy consuming techniques to purify water. Present study is therefore aimed at the synthesis of an adsorbent using agricultural waste i.e. coconut shell. The charcoal obtained from coconut shell was modified by acid activation and manganese doping following a simple chemical route. The products were characterized by scanning electron microscopy, energy dispersive X-ray analysis and infrared spectroscopy. Preliminary studies were carried out to compare the adsorption potential of acid modified coconut shell charcoal (AMCSC) and manganese doped coconut shell charcoal (MDCSC) for the removal of chromium (VI) and iron (III) from aqueous solutions. Various physicochemical parameters such as adsorbent dosage, initial metal ions concentration and pH were studied. MDCSC was found to be a better adsorbent for metals as compared to AMCSC and removed chromium more efficiently than iron from synthetic solutions i.e. 56.10% at optimum conditions i.e. 0.6 g/L adsorbent dosage, 10 mg/L initial metal ions concentration and pH = 3. The effect of adsorbents on color and conductivity of the aqueous solutions was also noted; slight variation in color of all the aqueous solutions with a maximum of 91.67% removal was observed.

A simple solvent extraction method was used to analyze alcohol-based hand rubs (ABHRs) using gas chromatography with a flame ionization detector. 79 samples including 68 liquid and 11-gelled ABHRs were analyzed in the Food and Drug Laboratories Research Center of Mashhad, Iran. 17 samples had methanol, 50 samples had the correct percentage of alcohol (60-80%), and 12 samples had the incorrect percentage of alcohol (<60%). The RSD% of methanol, ethanol, and isopropanol were as 2.28, 2.18, and 1.52, respectively. The relative recoveries for methanol, ethanol, and isopropanol were 102.5, 97.8, and 114, respectively. All experiments were repeated three times. The limit of detection and the limit of quantification for methanol, ethanol, and isopropanol were obtained as 0.22, 0.24, 0.10 (%) and 0.71, 0.82, 0.68 (%), respectively.

Ni(II), Cu(II), and Zn(II) complexes of the tridentate heterocyclic ligand, 2-(phenyl(pyridin-2-yl)methylene)hydrazine-1-carbothioamide (HL) have been synthesized and characterized by various spectroscopic techniques and elemental analyses. Infrared spectroscopy shows that the ligand coordinates to the metal ions through the azomethine and pyridine nitrogen atoms as well as the sulfur atom of the thioamide group to form a tridentate chelate system. In vitro screening of metal complexes against four bacterial strains (Staphylococcus aureus (ATCC 43300), Klebsiella pneumoniae (ATCC 700603), Methicillin resistant staphylococcus aureus (ATCC 33591), Shigella flexneri (NR 518)) and four fungal strains (Candida albicans (NR 29444), Candida albicans (NR 29445), Candida albicans (NR 29451), Candida krusei (HM 1122)) indicate that the Cu(II) complex showed good antibacterial activity on Methicillin resistant staphylococcus aureus (ATCC 33591) while the Zn(II) complex showed moderate activity against some of the bacterial and fungi strains. Antioxidant studies reveal that the complexes are more potent than the ligand to eliminate free radicals, with the Ni(II) complex showing the best free radical scavenger.
