Authors: Talattov Abrapuspa Ghani , Sanusi Nur Azura , Kusairi Suhal , Shaari Abu Hassan
Published: March 2018

In the finance literature, the relationship between capital structure and firm value has been extensively investigated, both theoretically and empirically. The main issue on corporate finance is how firms dealing with the important decision of capital structure. In this study, a model of capital structure is formulated in which corporate tax and zakat payment exist by firms into the consideration of combination of debt and equity. The theoretical model as shown by comparative statics prove the implication which is negatively relationship between leverage of the firm and the corporate zakat payment. Meanwhile, the empirical evidence reveals several implication as follows, (1) tax deduction reduces the current liability item relative to the firms that prefer equity financing, (2) the significant of zakat is consistent with the theoretical model that zakat would encourage firm to issue more equity than debt, (3) the strong significant relationship between return on assets with the leverage are the leading indicator of capital structure in all models.Keywords: Capital structure, Corporate tax, ZakatJEL Classification: C33, G32, H2

Authors: Ihsan Hidayatul , Sulaiman Maliah , Mohd Alwi Norhayati , Akhyar Adnan Muhammad
Published: March 2018

This study aims to address the issue of accountability in a waqf institution. Specifically, the focus of this study is to shed more light on how the mutawalli (waqf trustee) discharges accountability in managing waqf. In so doing, an interpretive case study in one Indonesian waqf institution, that is, Dompet Dhuafa (DD), was undertaken. The data were obtained through semi-structured interviews. Other sources of data collection techniques employed along with the interviews include observations and document reviews.  Furthermore, this study uses the accountability mechanisms as the conceptual lens. The accountability mechanisms consist of disclosure statements and reports, performance assessment, participation, self-regulation and social auditing. In addition to the accountability mechanims, the stakeholder salience theory is also used to understand how the mutawalli shows accountability to multiple stakeholders. The findings of this study reveal that although DD recognizes the salient nature of its stakeholders, it does not prevent the mutawalli from showing accountability to all stakeholders. The mutawalli is of the view that accountability is not limited to accounting and reporting. Moreover, the mutawalli believes that showing accountability to different groups of stakeholder requires different mechanisms of accountability. As such, this study concludes that DD’s commitment to accountability is proven through its effort to deal with stakeholder salience. Keywords:  Waqf, accountability, accountability mechanisms, stakeholder salienceJEL Classification: L31, M49, N35
DEVELOPING ISLAMIC WAQF BANK AS A MECHANISM FOR FINANCIAL SYSTEM STABILITY
Authors: Ab. Aziz Muhammad Ridhwan
Published: March 2018

The establishment of Islamic banking institution all over the world is often related to the proclivity of muslims to live all aspects of their lives in accordance with the teachings of Islam. Islamic bank is one of the components in Islamic financial sector that plays very vital role to generate the growth of economics among muslim society. Indeed, Islamic bank was more robust to the financial crisis compared to the conventional banking institution. Cash waqf is a trust fund established with money to provide services to mankind in the name of Allah. The gifted capital then will be spent for all sorts of pious and social purposes inclusive for the financing and investment objectives. It is recognized that there is limited study in the area of cash waqf especially in the development of Islamic waqf bank (IWB). The main objective of this article is to analyze the possibility and obstacles in developing IWB in the mainstream Islamic financial institutions. The methodo-logy of research in this article is through a qualitative research based on interview with relevant officers in the Islamic banking, waqf, and academic sectors. The general finding in this article shows that IWB can apply cash waqf structure, whereby the cash waqf fund must be converted into fixed assets such as land and buildings. The rental income from the fixed assets and investments then can be channelled to waqf beneficiaries such as funding students’ education, health assistance, giving financing to the entrepreneur, and enhancing muslim economy in various fields. Nevertheless, a proper mechanism of IWB must be developed in order to avoid any obstacles in terms of capital requirement, risky investment, limited number of experts in the field of Islamic bank and waqf as well as legal and regulation requirement.Keywords:   Islamic Waqf Bank, Cash waqf, Islamic finance, Financial system stabilityJEL Classification: G21, I31, L31
THE ROLE OF ISLAMIC CAPITAL MARKET FOR MICRO, SMALL, AND MEDIUM ENTERPRISES (MSMES) THROUGH SYNERGY OF MUTUAL FUND AND VENTURE CAPITAL INSTITUTION
Authors: Sanrego Yulizar D.
Published: March 2018

It is worldly known that one of the main obstacles which is often faced by the micro, small, and medium enterprises (MSMEs) practitioners is the ability to access sources of funding. At the time where the absorption of banking credit to MSMEs is still very limited, the role of sharia capital market is considered as an alternative to support this limitation. Expanding the role of sharia capital market finds it moment when Indonesia Finance Service Authority (FSA) issued regulations that provide space for the capital market to also active in real sector businesses. In accordance with the FSA Rules N0.37/2014, mutual fund (unit trust) in the form of Collective Investment Contract (CIC) - Limited Investment/ Participation Fund (LPF) has the objective to pave the way for mutual fund investors to make direct investments in real investments. The proposed model that might be realized to smoothen the intermediary role of sharia capital market to the development of MSMEs is through the hybrid model that might linking mutual fund/investment manager and corporate, particularly venture capital. Using Analytical Network Process (ANP) approach this paper indicates that with the value of rater agreement 1.0, the research found that there are four main cluster problems which become an obstacle the proposed model, namely: (a) the reputation of mutual fund/investment manager; (b) investment grade rating of corporate (venture capital); (c) risk appetiate of investor as shahib al-mal; and (d) government regulation. Policy recommendation that might become solution, according to the value of rater agreement 1.0  is sequentially as follow, namely: (a) fully support from government; especially for a relatively new mutual fund with no experience in the capital markets industry; (b) Corporate (venture capital) should be able to offer Islamic Microfinance Finance Institutions (IMFIs) and MSMEs that have good business feasibility to the mutual fund/investment manager as well as investor; (c) the government should be able to guarantee legal certainty in the context of protection, including advocacy for investors; and last but not least (d) There is an extremely hope that investors could change their investment behavior paradigm, from risk averse to risk taker.Keywords: Sharia capital market, Mutual fund, Venture capital, MSMEJEL Classification: G1, G23, G24

Authors: Reig Ferrer Abalio , Caruana Agustín
Published: March 2018

En este capitulo hemos analizado el grado de estrés percibido asociado a la posibilidad de tener pacientes con SIDA en 93 Profesionales de la salud que trabajan en hospitales. El 32% de la muestra asocia unos niveles altos de tensión a esa posibilidad. No existe una diferencia significativa entre médicos y enfermeras en cuanto a estrés percibido asociado al SIDA, mostrándose como poco relevantes las variables sociodemográficas en la determinación del nivel de estrés. Los estresores asociados a niveles altos de tensión en relación al SIDA tienen que ver con aspectos como la probabilidad de contagio nosocomial causal, no poder resolver con satisfacción los problemas que se plantean, tener que informar, ver de cerca la muerte, mantener la confianza en uno mismo e inspirar confianza en los pacientes, y los derivados de las complicaciones en el tratamiento. Ambos grupos presentan, además, estresores específicos diferentes. En los médicos, aquellos como presentar casos a sesiones clínicas, decidir que aspectos son prioritarios, el trabajo agotador, hablar con los pacientes, ect.; mientras que en enfermería se circunscriben más a nivel asistencial (atender en situaciones de urgencias, o a pacientes moribundos/terminales, o graves). Con todo, mediante análisis de regresión múltiple, comprobamos que es en el grupo de médicos donde la posibilidad de contagio nosocomial constituye la principal causa de estrés asociado a tener pacientes con SIDA (coef. regresión estándar: 0.45), Mientras que el peso es menor en enfermería: posibilidad de contagio (0.35), Tener que informar (0.33), asistencia a casos urgentes (0.31), que son coef. de regresión estandarizados con niveles de significación bajos.

Core Ideas

Dry matter yields increased with N inputs although efficiency decreased.

Applying nitrogen at 67 kg N ha–1 was superior in both yield and efficiency.

Delaying the time of harvest until late fall or a killing frost increased yield.

Native perennial warm‐season grasses (NPWSG) have drawn interest as bioenergy feedstocks due to their high productivity with minimal amounts of inputs under a wide range of environments. Nitrogen fertility and harvest timing are critical management practices when optimizing biomass yield of NPWSG. Our objective was to quantify the impact of N fertilizer rate and timing in combination with harvest timing and frequency on NPWSG yield. Research was conducted in 2014 and 2015 on four field‐plot locations in Missouri. The experiment was a split‐plot design with three replications where N rate and harvest timing were the main and sub‐plot treatments, respectively. Nitrogen rates were 0, 34, 67, and 101 kg N ha−1 with two application timings, all early spring and split N (early spring and following first harvest). Harvest timing included two single (September and November) and two double harvests (June followed by September or November) per year. Delaying harvest until November increased yield across sites. November harvest and N rates ≥67 kg ha−1 improved NPWSG biomass yields. Although N fertilization improved yield, partial factor productivity (PFP) of applied N did not increase with annual N rates >34 kg ha−1. Fertilization at 67 kg ha−1 yr−1 provides an opportunity to maintain a balance between yield and N efficiency. These results demonstrated that N fertilization and harvest management of NPWSG were not always independent, and therefore these practices should be simultaneously considered. For example, early‐season harvesting suppressed response to N when the second harvest was not delayed until after frost.
Irrigation Timing and Rate Affect Cotton Boll Distribution and Fiber Quality

Published: March 2018

Core Ideas

Timing of water deficit stress affects boll production.

Stress timing influences fiber quality.

Multiple timings of water deficit stress interact.

Decreased aquifer water in the Texas High Plains has increased the risks associated with irrigation, including lower irrigation volume and the need to balance seasonal water demands among crops, requiring management of both irrigation rate and timing. Boll distribution measurements in cotton (Gossypium hirsutum L.) can be used to quantify the effects of irrigation on productivity and were used in a study of irrigation rate × timing from 2011 to 2013 in Halfway, TX. Field experiments quantified cotton boll distribution using three in‐season irrigation levels (maximums of 0, 3.2, and 6.4 mm d−1) during three different irrigation periods determined by accumulated growing degree days (GDD) based on the threshold of 15.6°C: period 1 (P1, <525 GDD), period 2 (P2, 525–750 GDD), and period 3 (P3, >750 GDD). Combinations of these factors resulted in 27 irrigation treatments, applied with a low energy precision application (LEPA) pivot. Heavy irrigation early in the growing season used more water, did not increase boll number, and was often detrimental to yield. Mid‐ and late‐season irrigation improved yield and fiber quality, with P2 irrigation influencing yield in the middle of the plant and P3 irrigation controlling yield at the top of the plant. Moderate irrigation later in the season minimized effects of short‐term water deficit observed in other similar studies. These results provide insight into optimizing cotton water use in a region with declining crop water availability, increased pumping restrictions, and a challenging climate.

Core Ideas

Quantified high‐temperature intensity, frequency, and duration as HDH index.

High‐temperature episodes between booting and flowering increased significantly.

High‐temperature episodes had a significant negative effect on rice yield.

Booting and flowering stages of rice are most sensitive to high‐temperature episodes. However, the effect of spatial‐temporal characteristics of high‐temperature episodes on booting and flowering stages in the middle‐season rice cropping region of China were less commonly found in the literature. A data analysis of historical climate and rice yield was conducted to characterize the spatial and temporal variability of high‐temperature episodes between booting and flowering stages and their impact on middle‐season rice grain yield in China. Three high‐temperature indices, including high‐temperature hours (HH), high‐temperature intensity (HI), and high‐temperature degree hours (HDH), were developed to quantify the high‐temperature intensity, frequency, and duration based on maximum temperature records of the last 30 yr from 219 stations in the main middle‐season rice cropping area of China. The HH and HI indices between booting and flowering stages increased significantly in all subregions. Especially in the Central China (CC) subregion, high‐temperature episodes were more severe than those in the East China (EC) subregion and Southwest (SW) subregion. The HDH index, considering the duration and intensity of high‐temperature episodes, was required to describe the correlation between high‐temperature episodes and yield variability. Significant negative (p < 0.05) impacts of the variability of high‐temperature episodes on the observed grain yield were found in all subregions. Rice yield would decrease by 113.9 kg ha−1, 19.1 kg ha−1, and 22.2 kg ha−1 with an HDH increase of 1.0°C·d in the EC, CC, and SW subregions, respectively. High‐temperature episodes were detrimental to middle‐season rice production of China.

NAC (NAM, ATAF, and CUC) transcription factors function as the nodes of regulatory networks in response to various biotic and abiotic stresses. Although they have been widely studied in many species, no knowledge concerning salt‐stress‐responsive NAC genes is available in sweetpotato (Ipomoea batatas L.). In the present study, 12 novel putative NAC genes, designated as IbNAC1L and IbNAC3 through IbNAC13, were isolated on the basis of the salt‐stress‐treated RNA sequencing data of two sweetpotato cultivars (‘XuShu 22’ and ‘XuShu 32’) with different levels of salt tolerance. Motif compositions showed that all the IbNAC proteins except IbNAC9 contain five conserved subdomains in the NAC domain region that characterizes the NAC gene family. Furthermore, systematic expression analysis and function evaluation of these IbNAC genes were conducted using quantitative real‐time polymerase chain reaction. The results showed that the expression of most IbNAC genes was exclusively induced by multiple abiotic stresses, including NaCl, dehydration, cold, and heat. Varying degrees of induction were also observed in the transcription levels of these IbNACs, except IbNAC10, when treated with various hormones, including abscisic acid, 1‐aminocyclopropane‐1‐carboxylate, gibberellic acid, and jasmonic acid. Cumulatively, the data of stress‐responsive IbNAC genes in the present study will provide valuable information for further exploring the crucial and diverse roles of IbNAC genes in sweetpotato stress tolerance.

Published: March 2018

Este artigo articula uma discussão sob o ponto de vista de Ciência, Tecnologia e Sociedade (CTS) sobre a matriz energética brasileira, com o objetivo de verificar as perspectivas da utilização da energia advinda das ondas do mar em energia elétrica. Parte-se do histórico mundial, iniciado por Japão e Portugal, que desenvolvem projetos sobre o aproveitamento da energia das ondas oceânicas desde a década de 70. No Brasil a matriz energética foi impulsionada e construída com base na construção de hidrelétricas consolidando um paradigma o qual é discutido num contexto de CTS. Tal matriz, no Brasil, obteve um ápice de geração e distribuição, mas a partir da década de 80 vem apresentando falhas no atendimento das demandas em alguns territórios nacionais. O cenário energético mundial vem desenvolvendo estudos para a utilização de fontes alternativas de energia sustentável dentre elas as ondas oceânicas. Através dessa discussão á luz do campo CTS o artigo propõe a interposição de outro paradigma, sem desconsiderar a análise pela sociedade quanto o seu papel no cenário energético.

Adaptation and mitigation synergies to improve sanitation: a case study in Morelos, Mexico
Authors: González Ines Navarro , Cisneros Blanca Jiménez , Hernández Nidya Aponte , Rojas Raquel Montes
Published: March 2018

The management of wastewater is the fifth largest single source of CH4 emissions and the sixth of N2O. Options to improve sanitation within the Morelos State in Mexico were compared applying a modification of the IPCC guidelines to estimate greenhouse gas (GHG) emissions. A 2030 business-as-usual scenario which considers current sanitation practices and 2010 baseline-scenario, showed that septic tanks, the main state option for sanitation, were the principal source of emissions, even higher than from non-controlled wastewater discharges. These scenarios also revealed that the two metropolitan areas were key in terms of mitigation as they contributed 88% of the total GHG emissions. For the 2030A scenario (sanitation + adaptation), it was seen that if the policy of septic tank usage continues, and the existing wastewater treatment plants (WWTPs) are rehabilitated, the GHG emissions would be reduced by 2% compared to the business-as-usual (BAU) scenario. In contrast, if a policy were adopted considering in addition mitigation measures, 26% GHG emissions reduction might be achieved. Additional co-benefits will be obtained in several sectors, including health (diarrheal and dengue diseases control), agriculture, and the environment, performing a more efficient and integrated management of water and achieving savings on the operating costs of WWTPs through co-generation.

Published: March 2018

The contamination of natural resources with mercury has gained attention due to its high toxicity to all life forms. Bioremediation of mercury using bacteria is a useful technique to remediate mercury contamination. In the present study mercury resistant bacteria (MRB) were isolated from Mithi River water samples. Total heterotrophic bacteria (THB) and MRB present in the Mithi river water samples were enumerated. The count for THB was found to be 3.7 × 106 CFU/ml. MRB enumerated in the nutrient agar medium with mercury concentrations of 50, 100 and 150 ppm had counts of 2.8 × 106, 9.1 × 105 and 5.8 × 104 CFU/ml, respectively. The minimum inhibitory concentration (MIC) of the isolated bacterium was found to be around 500 ppm of mercury, and it was selected for further analysis. The bacterial isolate was found to tolerate a wide range of salt concentrations from 5 to 35 ppt of NaCl. The bacterial isolate was characterized by using standard biochemical tests and identified by using the 16S rDNA technique. Homology analysis of the 16S rDNA gene has confirmed the identity of the bacterium as Bacillus thuringiensis strain RGN1.2 with NCBI accession no. KX832953.1. It could remove 96.72%, 90.67% and 90.10% of mercury in 48 hours at 10, 25 and 50 ppm of mercury.

A amostra da pesquisa foi composta por todas as companhias abertas não financeiras que estão listadas nos níveis de governança corporativa da BM&FBOVESPA no período entre 2008 a 2013. Assim, para atender o objetivo da pesquisa foram utilizadas as modelagens de Frank e Goyal (2003). Os resultados indicam que de forma geral as empresas do estudo não seguem a POT. Contudo, verificou-se que as empresas do Novo Mercado têm maior tendência de seguir a hierarquia de financiamento quando comparadas organizações dos outros níveis. Os achados contrariam o resultado esperado, uma vez que as empresas do Novo Mercado, por apresentarem melhores práticas de governança corporativa, deveriam apresentar resultados mais distantes de seguir a POT. Assim, conclui-se que a hipótese do estudo que as empresas com maior nível de governança corporativa não utilizam uma hierarquia de financiamento, foi rejeitada
Chronic Wounds: Innovations in Diagnostics and Therapeutics
Authors: Haalboom Marieke
Published: March 2018

Background:

A major global health issue is the existence of chronic wounds. Appropriate
diagnosis and treatment is essential to promote wound healing and prevent further
complications. Traditional methods for treatment and diagnosis of chronic wounds have shown
to be of limited effectiveness. Therefore, there is a need for the development of diagnostic and
therapeutic innovations in chronic wound care.

Objective:

This mini-review aims to provide insight in the current knowledge of the wound
healing process and the deficiencies encountered in chronic wounds, which provides a basis for
the development of innovations in chronic wound care. Furthermore, promising diagnostic and
therapeutic innovations will be highlighted.

Methods:

Literature was searched for recent articles (=<10 years) describing the current
knowledge about the wound healing process and chronic wounds. The most promising diagnostic
and therapeutic innovations were gathered from articles published in the past 5 years.

Results/Conclusion:

Wound healing is a well-organized process consisting of four phases: coagulation,
inflammation, proliferation and wound remodelling. Chronic wounds often stagnate
in the inflammatory phase and/or experience an impaired proliferative phase. This mini-review
has demonstrated that increased knowledge about the processes involved in wound healing has
paved the way for the development of new diagnostic tools and treatments for chronic wounds.
Increased knowledge about bacterial invasion and infection in has encouraged researchers to
develop diagnostic tools to help clinicians detect these phenomena appropriately and in time.
Other researchers have shown that they are able to design/extract biochemical compounds that
intervene in the disrupted healing processes in chronic wounds.
Synthesis of 8,10-disubstituted-triazoloperimidines from (E)-3-(dimethylamino)-1-(8- phenyl-8H-[1,2,4]triazolo[4,3-a]perimidin-10-yl)prop-2-en-1-one and Their Antimicrobial Activity

Published: March 2018

Aim and Objective: Enaminones belay to be extremely stable compounds and constitute a versatile
group of salutary precursors for the synthesis of enormous classes of organic compounds. So, in this context,
we synthesized a new enaminone, namely, (E)-3-(dimethylamino)-1-(8-phenyl-8H-[1,2,4]triazolo[4,3-
a]perimidin-10-yl)prop-2-en-1-one (enaminone 2).

Materials and Methods:

The reaction of enaminone 2 with different types of hydrazonoyl chlorides or hydrazine
hydrate afforded new substituted pyrazoles. Also, the reaction of enaminone with 6-amino-2-
thioxopyrimidin-4-one in acetic acid under reflux produced 2-thioxopyridopyrimidinone derivative. The latter
thione derivative reacts with hydrazonoyl chlorides to give pyridotriazolopyrimidines. 5-(8-Phenyl-8H-
[1,2,4]triazolo[4,3-a]perimidin-10-yl)isoxazole was produced from the reaction of enaminone 2 with hydroxylamine.

Results & Conclusion:

The structure of all the novel perimidine derivatives was confirmed on the basis of
spectral data and elemental analyses. The enaminone and the newly synthesized compounds were tested for
their antimicrobial activity, and the results obtained revealed that some derivatives are more potent than the
reference drugs used.

Published: March 2018

Background: Magnetic targeting, which utilizes a magnetic field to specifically deliver
therapeutic agents to the targeted regions, can greatly improve the treatment efficiency. On the other
hand, glucose-modified nanoparticles have also demonstrated good brain-targeting abilities. Fusion
of both might further improve the brain targeting efficiency.

Objective: To prepare, characterize and evaluate glucose-modified ibuprofen-loaded brain targeting
magnetic nanoparticles (MNPs-APS-Glu).

Methods: The magnetic nanoparticles MNPs-APS-Glu were designed and synthesized in order to
effectively deliver ibuprofen to the brain through glucose transporter 1 (GLUT1) and an external
magnetic field. The nanoparticles were characterized by FTIR, SEM and magnetic properties, and
the drug loading capacity, cell cytotoxicity and drug release behavior of the new magnetic nanoparticles
was studied.

Results: The size of MNPs-APS-Glu was about 104.9 nm, and its drug loading capacity was up to
5%. Furthermore, these brain targeting magnetic nanoparticles maintained the magnetic property
with a saturation magnetization level at ca. 32 emu/g and could release ibuprofen when incubated
with various buffers, mice plasma and brain homogenate.

Conclusions: The results indicated that the magnetic nanoparticles had potential to be a promising
tool to selectively deliver drugs to the brain. This study may be conducive to the field of Central
Nervous System (CNS) drugs delivery.

Published: March 2018

Background:

The purpose of this study is to identifying time series analysis and mathematical
model fitting on electroencephalography channels that are placed on Amyotrophic Lateral
Sclerosis (ALS) patients with P300 based brain-computer interface (BCI).

Methods:

Amyotrophic Lateral Sclerosis (ALS) or motor neuron diseases are a rapidly progressing
neurological disease that attacks and kills neurons responsible for controlling voluntary muscles.
There is no cure and treatment effective to reverse, to halt the disease progression. A Brain-
Computer Interface enables disable person to communicate & interact with each other and with the
environment. To bypass the important motor difficulties present in ALS patient, BCI is useful. An
input for BCI system is patient's brain signals and these signals are converted into external operations,
for brain signals detection, Electroencephalography (EEG) is normally used. P300 based BCI
is used to record the reading of EEG brain signals with the help of non-invasive placement of
channels. In EEG, channel analysis Autoregressive (AR) model is a widely used. In the present study,
Yule-Walker approach of AR model has been used for channel data fitting. Model fitting as a form of
digitization is majorly required for good understanding of the dataset, and also for data prediction.

Results:

Fourth order of the mathematical curve for this dataset is selected. The reason is the high
accuracy obtained in the 4th order of Autoregressive model (97.51±0.64).

Conclusion:

In proposed Auto Regressive (AR) model has been used for Amyotrophic Lateral
Sclerosis (ALS) patient data analysis. The 4th order of Yule Walker auto-regressive model is giving
best fitting on this problem.
On-chip Mixing, Pumping and Concentrating Effects by Using AC Electrothermal Flow
Authors: Vafaie Reza H.
Published: March 2018

Background:

Microfluidic manipulation (including: pumping, mixing and concentrating effects) is highly challengeable for bioengineering and on-chip analysis applications such as point-of-care immune-detection systems. In this research we propose a configurable electrode structure to form various manipulation effects including pumping, mixing and concentrating processes by applying an Alternate Current (AC) electrokinetically-driven flow.

Methods:

By applying an inhomogeneous electric field causes temperature rise accompanied by temperature gradients generation inside the microchannel. As a result, an AC electrothermal flow generates inside the channel, which is efficient to generate mixing, pumping and concentrating effects.

Results:

The proposed system is studied numerically by Finite-Element-Method, Based on the results, a) bulk fluid velocity of 100 µm/s is achieved by exciting the electrodes in pumping mode, b) complete mixing efficiency is observed in mixing mode, c) for antibody-antigen binding process (concentrating mode), the surface reaction increases by the factor of 9 after 5 seconds of sample loading. Results reveal that the system is highly efficient for bio-fluid mediums.

Conclusion:

AC electrothermal fluid manipulation process was investigated numerically inside a microchannel for biological buffers. Back and forth fluid motions, clockwise/counter-clockwise rotational vortexes and also antibody-antigen linking enhancement were achieved by engineering the specific electrode patterns. The manipulation efficiency improves by increasing both the amplitude of electric potential and the ionic strength of biofluid. As a result, our proposed configurable device is of interest for onchip immunoassays and point-of-care devices.
