RELEVANCE AND PERSPECTIVES OF EXPERIMENTAL WOUND MODELS IN WOUND HEALING RESEARCH
Authors: Lodhi Santram , Vadnere Gautam P
Published: July 2017

The wound healing process consists of four highly integrated and overlapping phases: Hemostasis, inflammation, proliferation, and tissue remodeling. These phases and their biophysiological functions must occur in the proper sequence, at a specific time and continue for a specific duration at an optimal intensity. There are many factors that can affect wound healing which interferes with one or more phases in this process, thus causing improper or impaired tissue repair. This review was aimed to collect data and made a critical analysis. This will provide concise information regarding different models and parameters used for wound healing study. The data related to different wound models are collected using popular search engines as well as relevant science search engines and database including Google Scholar, Science Direct, and PubMed. A new drug substance can be evaluated for wound healing activity using different in vitro models such as cell culture, chick chorioallantoic membrane model, tube formation on metrigel and capillary growth model. The in vivo wound models such as incision, excision, dead space, burn wound, ischemic wound, and diabetic wound models are frequently used. Each model has specific importance. The limitations and advantages of each are described in this review. Although animal wound repair is an imperfect reflection of human wound healing and its clinical challenges, these models can be fundamental tools for the development of new approaches to rational wound therapy.

The importance of medicinal plants in traditional health-care practices provides clues to new areas of research and in the biodiversity of conservation. Right from the beginning, the documentation of traditional knowledge, especially on the medicinal uses of plants, has provided many important drugs for the modern day. Even today, this area holds much more hidden treasure as almost 80% of the human population in developing countries depend on plant resources for health care. Keeping this in view, the present study was initiated to document the traditionally used tribal plants and their inborn antimicrobial activity which is enhanced on the synthesis of noble metal nanoparticles.

SPECTROPHOTOMETRIC EVALUATION OF NIMESULIDE IMPURITY D: 4-NITRO-2- PHENOXYANILINE USING 8-HYDROXYQUINOLINE AS OXIDATIVE COUPLING REAGENT
Authors: S Anil Kumar , Bl Bhaskar
Published: July 2017

Objective: Spectrophotometric investigation of 4-nitro-2-phenoxyaniline (4N2PA), a probable intermediate during the synthesis of anti-inflammatory drug nimesulide, both in pure form and in the presence of nimesulide has been attempted. Methods: 4N2PA on diazotization followed by coupling with 8-hydroxyquinoline produces a crimson-colored complex which changes to deep violet on diluting with ethanol. Results: The complex showed maximum absorbance at 560 nm when evaluated spectrophotometrically with a detection limit of 0.005 μg/ml and quantification range of 0.05-3.0 μg/ml. The method has been statistically evaluated with respect to the International Council for Harmonisation guidelines and found to be accurate and precise. Conclusion: Pure tablet formulations of nimesulide do not respond to the method; however, the presence of minute amounts of 4N2PA in the drug as added impurity could be spectrophotometrically analyzed. Hence, the authors suggest that the reported technique could be a marker test for detecting the presence of 4N2PA in nimesulide formulations.

Published: July 2017

Objective: In this investigation, the amleorative role of esculetin (Esc) was investigated in gentamicin (Genta) nephrotoxicity in rats and the possible role of N-methyl-D-aspartate receptors (NMDAR) in genta-induced nephrotoxicity.Methods: Genta (100 mg/kg/day, i.p. for 7 days) was administered to rats for the induction of nephrotoxicity, and subsequently, the extent of renal damage was measured by estimating creatinine clearance (CrCl), blood urea nitrogen (BUN), uric acid, microprotienuria and fractional excretion of sodium, and potassium. In addition, renal superoxide anion generation (SAG), Thiobarbituric acid reactive substance (TBARS), and reduced glutathione (GSH) level were used to evaluate renal oxidative parameters. Renal myeloperoxidase (MPO) activity was used to measure renal inflammation. D-serine, NMDA agonist was used in this study to evaluate the role of NMDA antagonist in genta-induced nephrotoxicity. Histopathological examination was performed using hematoxylin and eosin staining method.Results: Genta-treated rats exhibited remarkable changes in renal parameters like increase in BUN, uric acid, microprotein fractional excretion of sodium and potassium with decrease in CrCl and similarly biochemical parameters like increase in SAG, thiobarbituric acid reactive species (TBARS), MPO activity with decrease in GSH level. Treatment with Esc (5 and 10 mg/kg/day, i.p for 7 days), NMDAR antagonist attenuated the genta-induced nephrotoxicity but did not shown significant effect on combined use of genta and D-serine treated group. Histopathological examination of gentatreated rats. The coadministration of Esc + genta-protected kidney tissue from nephrotoxic effect of genta as illustrated by normalization of tubules but not with the combined use of Esc + genta + D-serine treated rats.Conclusion: Esc displayed protective effect in genta-induced nephrotoxicity but combined effect of Esc + genta + D-serine abolished the protective effect of Esc thus confirming that NMDAR may be involved in genta-induced nephrotoxicity.

Recibido: 01/02/2017 • Aceptado: 15/10/2017

En este artículo me propongo comentar los conceptos y argumentos centrales del texto “Habitar la ciudad” de Juan Carlos Mansur. En la primera parte del texto comento las nociones de “arraigo”, “ciudad” y “proximidad” a partir de las intuiciones que algunos filósofos han tenido sobre ellos (S. Weil, M. Zambrano o Hesíodo). En la segunda parte, intento argumentar a favor de la idea de que la habitación más primaria es la que ocurre en la intimidad de la persona, y de ahí parte hacia el exterior, comenzando con la habitación propia, luego la casa, más tarde el barrio y, finalmente, la ciudad. Concluyo con la puesta sobre la mesa de algunos problemas de la ciudad contemporánea y apunto algunas ideas que sugieren el camino hacia el que tendría que ir el ciudadano y el arquitecto para hacer la de la ciudad un sitio habitable.

 
Chemical Evaluation of the Glass Making Potentials of Silica Sand Deposits Along Cross River in Cross River State, South–East of Nigeria
Authors: Anaekwe Nicholas Ogbonna , Hassan Yusuf Mi kailu
Published: July 2017

Analytical techniques such as X–ray Fluorescence Spectroscopy (XRF) and Atomic Absorption Spectroscopy (AAS) coupled with statistical package for multivariate analyses were used to characterize silica sand deposit obtained along Cross River in Cross River State, South Eastern Nigeria. Samples were collected from five locations along the river which include: Ikom-Okuni, Obubra-Ofumbogha, Abi-Ediba, Biase-Agwagune and Etung-Effraya. The results of analyses revealed that silicon dioxide (SiO2) forms the predominant metal oxide in the entire samples followed by iron oxides (Fe203), sodium oxide (Na20). Other Oxides such as aluminum oxide (AI2O3), potassium oxide (k2O) etc were also present. Further beneficiation of the silica sand samples gave increased silica dioxide content across all the samples and increase and decrease of other metal oxides. The acid demand value (ADV) and pH value of the silica sand determination revealed a moderately low ADV and neutral pH value of all the samples. A correlation between the mean values of SiO2 and Fe2O3 in all the samples across all the sampling locations showed an inverse relationship between SiO2 and Fe2O3. Furthermore, comparison using population t – test of observed mean of SiO2 and Fe2O3, with their observed minimum standard (90.52%, 0.005%) shows that the silica sand samples from Ediba and Agwagune can be used as a source of SiO2 for glass making due to their high SiO2 and low levels of Fe2O3 content.

Authors: Katuri Rayudu , Yesuratnam Guduri , Jayalaxmi Askani
Published: July 2017

One of the important tasks of a power system engineer is to run the system in safe and reliable mode for secure operation with increase in loading. So, it is significant to perform voltage stability analysis by optimal reactive power dispatch with Artificial Intelligence (AI) techniques. This paper presents the application of Ant Colony Optimization (ACO) and BAT algorithms for Optimal Reactive Power Dispatch (ORPD) to enhance voltage stability. The proposed ACO and BAT algorithms are used to find the optimal settings of On-load Tap changing Transformers (OLTC), Generator excitation and Static Var Compensators (SVC) to minimize the sum of the squares of the voltage stability L– indices of all the load buses. By calculating system parameters like L-Index, voltage error/deviation and real power loss for the practical Equivalent of Extra High Voltage (EHV) Southern Region Indian 24 bus system, voltage profile is improved and voltage stability is enhanced. A comparative analysis is done with the conventional optimization technique like Linear Programming (LP) for the given objective function to demonstrate the effectiveness of proposed ACO and BAT algorithms.

The model is  generated  in  Simulink  toolbox  of  MATLAB  and  results  are  obtained for steady state, transient and dynamic conditions. It is observed that the unity power factor is maintained during all the conditions  for  various  loads.  Drastic  reduction  in  %THD  of  input  current  waveform  is  obtained  in  proposed  power  supply  with   an   added   advantage   of   regenerative   capability.   For   comparison of results of control-loops, a programming file (M-file)  is  also  generated  in  MATLAB  and  from  the  same  file  the  step-response   and   Nyquist   plots   are   obtained   for   system   control-loops.  The  experiment  results  are  also  obtained  for  the  prototype   converter   in   inverter   mode.   The   power   system   friendliness of the proposed front-end converter is quite evident from the results presented in the paper.
Simulation of Storage Systems for increasing the Power Quality of Renewable Energy Sources
Authors: J. Mendez  , A. Falcon  , D. Hernandez
Published: July 2017

The use of renewable energy sources (RES) in
electricity generation has many economical and environmental
advantages, but has a downside in the instability and
unpredictability introduced into the public electric systems.
High variable energies such as wind power have a lack of
stability and, to avoid short-term variations in power supplied to
the grid, a local storage subsystem can be used to provide
higher quality in the fed energy. This paper contains a
mathematical model and a simulator focused on energy
management that may be useful to evaluate the service quality,
the energy efficiency and the required storage capacity

Published: July 2017

This paper presents the study accomplished to select the
electrical generator implemented on a new design of Wave
Energy Converter (WEC), identifying the key features that must
be taken into account when studying the feasibility of a power
plant for a given location and rated power. After introduced the
proposed WEC, a review of different solutions adopted by other
WEC system is presented. After an introduction of synchronous
and asynchronous generator families, their means of working
with variable speed and their capability to work connected to
grid or isolated is explained. Both of them can work with
variable speed, therefore the influence of selected generator in
the control strategy and the efficiency gain working with
variable speed is studied. The cost of the generation system and
the investment return of the facility play an active role when
selecting the generator system. After discussed their
characteristics advantages and influence in the efficiency, some
references will be given to take into account in the design
procedures to define a WEC system for a given location.
A Study of the Current Disturbance Caused by Wind Induced Vibrations of Photovoltaic Modules
Authors: J. Schmid  , E. Kancsar  , M. Drapalik  , V. Schlosser  , G. Klinger
Published: July 2017

Mechanical  vibrations  of  a  solar  module  mount-ing  rack  cause  oscillations  in  the  orientation  of  the  module  towards  the  sun.  The  resulting  intensity  oscillations  of    the  incident  light  originate  an  a.c.  current  at  the  module’s    termi-nals. We have investigated this effect in the laboratory by means of a vibration  table  and  outdoors  where  wind  forces  induce  vibra-tions  to  the  mounting  rack.  Although  the  collected  results  are  specific  and  restricted  to  our  experimental  set  up  and  environ-mental  situation  we  deduce  that  vibration induced current tran-sients  and  oscillations  of  a  solar  module’s  output  most  often  will  be  the  dominant  origin  of  distortion  in  the  low  frequency  regime.

Optimization of Battery Application for Wind Energy Storage
Authors: A. Danesh Shakib  , G. Balzer
Published: July 2017

The largest disadvantage of wind energy is the lack of exact predictability and its fluctuations, which are causing problems in the power system operation. The consequence is that even though other energy sources can be saved by using wind energy, the short-term power fluctuation has to be secured by a conventional plant. A possible solution can be the storage of wind energy. In this paper battery systems are analyzed as a backup for a 400 MW offshore wind farm with help of special developed calculation models. The goal is to reach small difference between forecasted and actual wind power and to increase the reliabilty of delivered wind energy using battery systems. For the determinations the properties of the battery system are considered and integrated into the calculation model. The overall target is to reduce the reserve energy requirement of the offshore wind farms.
Distributed Generation with Voltage Control Capability in the Low Voltage Network
Authors: F. Sulla  , J. Björnstedt  , O. Samuelsson
Published: July 2017

Small-scale distributed generators connected to
the low voltage network are generally operated with unity
power factor. However, controlling their reactive power
injection would have an impact on the voltage at their
connection point, if the network is sufficiently weak and
inductive. The purpose of this paper is to investigate how a
small-scale distributed generator connected to a low voltage
network through a power electronic converter can be controlled
to improve the voltage quality at its connection point.
The possibility to control the voltage at a point in the low
voltage network by reactive power injection is limited by two
factors, the small rating of the distributed generator compared
to the short-circuit power at its connection point and the
resistive nature of the low voltage cables. Here, a scheme for
inductively decoupling the distributed generator connection
point from the network is proposed and evaluated. For this
purpose, an inductance is placed between the network and the
generator, allowing voltage regulation by reactive power
injection.
Simulation results and lab measurements show that the
proposed scheme improves the voltage quality at the
microturbine connection point.

keaktifan sedang lebih baik daripada keaktifan rendah. Prestasi belajar siswa dengan tingkat
keaktifan tinggi, sedang, dan rendah yang diajar menggunakan metode Reciprocal Teaching lebih
baik daripada ceramah. Populasi dalam penelitian ini adalah seluruh siswa kelas X SMA Kyai
Ageng Basyariyah Sewulan Dagangan tahun ajaran 2012/2013. Sampel sebanyak dua kelas yaitu
siswa kelas X1 sebagai kelas eksperimen dan kelas X3 sebagai kelas kontrol. Pengambilan sampel
dilakukan dengan simple random sampling. Kelas eksperimen dilakukan dengan menerapkan
metode Reciprocal Teaching dan kelas kontrol dilakukan dengan menerapkan metode ceramah.
Dari hasil perhitungan diperoleh rata-rata untuk kelas eksperimen = 78,81 dan rata-rata untuk kelas
kontrol = 71,19 kemudian diuji dengan menggunakan analisis variansi dua jalan dengan sel tak
sama, dengan α = 0,05 diperoleh Fa hitung = 5,09 dan Fa tabel = 4,12, Fb hitung = 24,06 dan Fb tabel = 3,27,
Fab hitung = 0,22, dan nilai Fab tabel = 3,27, sehingga A H0 ditolak, B H0 ditolak, AB H0 diterima.
Sehingga dilakukan uji komparasi rataan antar kolom dan diperoleh F12 hitung = 8,31, F13 hitung =
41,47, F23 hitung = 17,50, sedangkan nilai Ftabel = 6,54 sehingga 12 H ditolak, 13 H ditolak, 23 H
ditolak. Ini berarti prestasi belajar siswa yang diajar menggunakan metode Reciprocal Teaching
lebih baik daripada ceramah. Prestasi belajar siswa dengan tingkat keaktifan tinggi lebih baik
daripada keaktifan sedang dan rendah, serta prestasi belajar siswa dengan keaktifan sedang lebih
baik daripada keaktifan rendah. Prestasi belajar siswa dengan tingkat keaktifan tinggi, sedang, dan
rendah yang diajar menggunakan metode Reciprocal Teaching lebih baik daripada ceramah.
Adapun sarannya, dalam mengajar matematika hendaknya metode Reciprocal Teaching ini dapat
dijadikan bahan pertimbangan bagi guru untuk meningkatkan prestasi belajar matematika dan
keaktifan siswa.
