Authors: Wicaksono Teguh Yudo 
Published: May 2018

Lucas - Rapping model is considered as successful model to explain the labor force in America. We are apply this model on Indonesian case to analyze the fluctuation of labor force and to know wether the shift on labor supply and unemployment is a function of current real wage or not. We also intend to analyze behaviour of household to respond the real wage change. From demand side, we can trace out how deep the education role on labor force quality. The conclusion may be helpfull on determining appropriate policy on education sector. We use data from BPS including Indikator Ekonomi dan Keuangan, Statistik Ketenagakerjaan (Sakernas), Keadaan Pekerja/Karyawan di Indonesia, Survei Sosial dan Ekonomi Nasional (SUSENAS) or Survei Penduduk Nasional (Supas). The rest of data is collected from international sources such as Summers Hestona PennWorld Table, data Barro and Lee and data Bank Dunia.
Sumber-Sumber Pertumbuhan Ekonomi Regional: Studi Empiris Antar Propinsi di Indonesia, 1984-2000
Authors: Wibisono Yusuf 
Published: May 2018

Studi ini menelaah eksistensi disparitas pendapatan regional di Indonesia. Dengan mempergunakan kerangka teori pertumbuhan neoklasik dan teori pertumbuhan endogen, studi ini menemukan bahwa tingkat konvergensi regional di Indonesia adalah rendah. Perbedaan dalam tingkat pertumbuhan secara sistematis dapat dijelaskan oleh sejumlah variabel penjelas.Perlakuan regresi yang mengizinkan fungsi produksi berbeda-beda untuk setiap perekonomian, menghasilkan estimasi kecepatan konvergensi yang jauh lebih tinggi. Hal ini mengindikasikan bahwa perbedaan tingkat teknologi antar propinsi adalah besar. Jika perbedaan dalam tingkat teknologi antar propinsi ini menghilang, maka konvergensi akan terjadi secara cepat.Dengan analisa konvergensi teknologi, studi ini menemukan bahwa mekanisme utama yang berada dibalik konvergensi regional adalah pengejaran TFP (Total Factor Productivity). Peranan pengejaran TFP ini jauh lebih dominan dibandingkan dengan akumulasi faktor. Dengan pendekatan transfer teknologi, studi ini membedakan antara konvergensi yang dihasilkan dari akumulasi faktor dan konvergensi yang dihasilkan dari transfer teknologi. Hasil analisa menunjukkan bahwa transfer teknologi memainkan peranan tidak kecil dalam konvergensi di Indonesia. Hal ini menegaskan temuan sebelumnya bahwa perbedaan tingkat teknologi antar propinsi adalah sangat lebar. Bila perbedaan ini menghilang, maka kita berharap bahwa transfer teknologi akan berjalan jauh lebih cepat. Transfer teknologi yang lebih cepat ini akan membawa pada konvergensi pendapatan yang juga lebih cepat.

The development of housing study in Indonesia is relatively behind compared with the progressivity of this study in other countries. This study is a preliminary study on housing sector in Indonesia which concerns with the factors determining the probability of a person to own a house which is also known as housing tenure choice. This study will also reveal the factors that affect the expectation of a household that doesn't own a house to own one. The explanatory variables in this model include age variables, highest educational achievement, and the category of job status of the household head marital status, number of household members, and access to housing credit (Kredit Pemilikan Rumah) which affects the probability and expectation of a household to own a house. To get the location aspect, we also estimate our model for urban DKI Jakarta, Java with the exception of DKI Jakarta, and Sumatera.The data utilized in this study comes from Indonesia Socioeconomic Survey (SUSENAS) 2001 which is the result of Indonesian Statistical Bureau (BPS) survey in all the provinces in Indonesia. This study focuses in urban area in Indonesia and use qualitative choice model in the estimation process. This study also focuses on multiple choices estimation process with logit model.The result shows that the proportion of Indonesian households which live in urban area and own a hose is 73% of the total households which is very big. The proportion of the households with rent/contract is 15.8%. DKI Jakarta has the biggest proportion of households with rent/contract which is about 31.4%. The estimation results of urban house ownership choice model in Indonesia show that number of household members, marital status, age of the head of the household and access to housing credit have a positive impact on the probability of a household to own a house (non rent/contract).From the study of the expectation of a household that doesn't own a house to own one we found that only 30% of Indonesian urban households have expectation to own a house for the next five years. Estimation of household expectation function to own a house shows that marital status, education level, income, and head of the household that works in formal sector have positive and significant impacts on the probability of a household to expect to own a house in the next 5 years. One of the most important results concerns KPR and government policy concerning KPR. The Data shows that only 6.37% of the urban households in Indonesia utilize this facility. Down payment and increase in the household expenses as a consequence of credit payment are two of the major factors causing low access of the

Abstract
The aim of the present study was to assess performance of waste stabilization ponds (WSPs) on the removal of Listeria spp. in Isfahan, Iran. A total of 104 samples were taken from eight sampling locations from influent and effluent of a wastewater treatment plant (WWTP). Sewage samples were analyzed for the presence of Listeria spp. using selective enrichment protocol. Listeria isolates were also identified by biochemical and polymerase chain reaction (PCR) amplification. Listeria spp. was enumerated by a three tube most probable number (MPN) for total coliform counts (TC), fecal coliform counts (FC), total suspended solids (TSS), and total dissolved solids (TDS). In total, 54/104 (51.92%), 49/104 (47.11%), 36/104 (34.61%), and 27/104 (25.95%) samples were positive for Listeria spp., L. monocytogenes, L. innocua, and L. seeligeri, respectively. The mean MPN/100 mL enumeration of L. monocytogenes for influent, anaerobic, facultative ponds 1, 2, 3, 4 and maturation ponds 1 and 2 were 21.54, 10.61, 8, 5.77, 4, 2.54, 1.38, and 0.46, respectively. The removal percentage of Listeria spp. in the anaerobic, facultative, and maturation ponds were 44.71, 76.5, and 81.4%, respectively. Results showed that the WSPs were able to decrease the Listeria spp. levels significantly, although unable to remove them completely.

Published: May 2018

Background:
Glioma is a heterogeneous, highly complicated central nervous
system (CNS) tumor with uncertain mechanism of initiation and progression, resulting in
an unfavorable outcome. An extended network of cytokines is recognized as a major
regulator of glioma pathogenesis, either promoting or inhibiting glioma progression based
on their type and specificity. Interleukin-8 (IL-8) has been revealed as a critical regulator
of CNS function and development with participation in many CNS disorders including
gliomas.

Objective:
The aim of the present review is to address the role of IL-8 in glioma pathogenesis
focusing on the implicated molecular pathways as well as on its potential targeting
for glioma therapy.

Methods and Results:
PubMed-Medline, SCOPUS, and Google Scholar databases were
searched for pre-clinical and clinical studies related to IL-8 implication in gliomagenesis
and IL-8 targeting strategies for gliomas. Literature data indicate that IL-8 participates in
glioma angiogenesis and cell migration and it can serve as a potential biomarker, for early
diagnosis, follow-up and response to therapy.

Conclusion:
Several promising approaches that target directly or indirectly IL-8 effects in
gliomas are currently in progress while more-in-depth studies are needed to validate its
biomarker role and elucidate the underlying molecular mechanisms.

Authors: Arenaccio Claudia , Chiozzini Chiara , Ferrantelli Flavia , Leone Patrizia , Olivetta Eleonora , Federico Maurizio 
Published: May 2018

Background:Eukaryotic cells release vesicles of different sizes under both physiological and pathological conditions. On the basis of the respective biogenesis, extracellular vesicles are classified as apoptotic bodies, microvesicles, and exosomes. Among these, exosomes are considered tools for innovative therapeutic interventions, especially when engineered with effector molecules. The delivery functions of exosomes are favored by a number of typical features. These include their small size (i.e., 50-200 nm), the membrane composition tightly similar to that of producer cells, lack of toxicity, stability in serum as well as other biological fluids, and accession to virtually any organ and tissue including central nervous system. However, a number of unresolved questions still affects the possible use of exosomes in therapy. Among these are the exact identification of both in vitro and ex vivo produced vesicles, their large-scale production and purification, the uploading efficiency of therapeutic macromolecules, and the characterization of their pharmacokinetics. </P><P> Objective: Here, we discuss two key aspects to be analyzed before considering exosomes as a tool of delivery for the desired therapeutic molecule, i.e., techniques of engineering, and their in vivo biodistribution/ pharmacokinetics. In addition, an innovative approach aimed at overcoming at least part of the obstacles towards a safe and efficient use of exosomes in therapy will be discussed.Conclusion:Several biologic features render exosomes an attractive tool for the delivery of therapeutic molecules. They will surely be a part of innovative therapeutic interventions as soon as few still unmet technical hindrances will be overcome.

Published: May 2018

Abstract: Background: Chlamydiae are widespread Gram-negative bacteria that cause a number of human diseases. Chlamydia trachomatis is the most prevalent sexually transmitted bacterial pathogen. </P><P> Methods: Fourteen novel phenazine derivatives were efficiently synthesized via Buchwald-Hartwig cross coupling reaction and Suzuki reaction from 4-bromo-1-methoxyphenazine. All the derivatives displayed antichlamydial activity with IC50 values from 1.01-19.77 &#181;M against Chlamydia trachomatis D and L2 for inhibiting progeny formation.Results:C-4 morpholinyl 8a and C-4 phenyl phenazine 9c exhibited stronger antichlamydial activity with no apparent cytotoxicity. Both phenazine derivatives inhibited chlamydial inclusions formation and growth in a dose-dependent manner. They inhibited Chlamydia infection by reducing elementary body infectivity and disturbing Chlamydia growth at the mid-stage of the chlamydial developmental cycle.Conclusion:Our findings suggest C-4 aryl and C-4 amino phenazine derivatives as promising lead molecules for antichlamydials development.

Authors: Subramaniyan Mahadevan , Subramaniyan Vijayakumar , Praveenkumar Arulmozhi 
Published: May 2018

Background:
Infectious diseases are major leading cause of death in all parts of the world,
because of the appearance of new multi drug resistant microbes. Therefore, the discovery of potential
drug for effective treatment will help the slaughter of the microbes. The aim of the present study is to
evaluate the presence of photochemical and antimicrobial activities of various crude extracts of leaves,
fruits and root bark of Atalantia monophylla and Atalantia racemosa against human pathogens by using
well diffusion method.

Methods:
Antimicrobial properties of the various extracts of Atalantia monophylla and Atalantia racemosa
were studied against some human pathogenic microbes such as Gram-positive Bacteria, (Bacillus
subtilis, Bacillus cereus, Staphylococcus aureus) Gram-negative Bacteria (Klebsiella pneumoniae,
Pseudomonas aeruginosa, Escherichia coli) and human opportunistic fungal pathogens (Candida albicans
and Aspergillus niger). All the extracts were comparable with standard drugs (Ciprofloxacin, Gentamicin,
Nystatin. and Amphotericin B). Minimum inhibitory concentration (MIC), minimum bactericidal
/fungicidal concentration (MBC/MFC) values were determined through a microdilution method.
The phytochemical analysis of these plant extracts were carried out using standard mthods.

Results:
Methanolic leaf extract of A. monophylla has showed excellent antimicrobial activity against
S. aureus (40mm). As well, the A. racemosa methanolic leaf extract shows notable inhibitory activity
against S. aureus (38mm). At the same time, the least inhibition was observed in aqueous extract of
A. monophylla against E.coli (9mm). The MIC ranged from 0.78 µg/mL to 50 µg/mL and MBC/MFC
1.56 to 50 µg/mL were recorded. Phytochemical analysis of alkaloids, steroids, saponins, flavonoids,
tannins, terpenoids, phenolics and cardiae glycoside were recorded in various extracts of A. monophylla
and A. racemosa respectively. Flavonoids, phenolics and cardiac glycoside were present only in
methonalic leaf extract of A. monophylla.

Conclusion:
The result of this study concluded that methanolic leaf extract has possessed novel compounds
with significant antimicrobial properties. Hence, we recommend this plant for further studies on
the isolation and characterization of that lead antimicrobial potential molecule.
A New Multiple-Dilution-Assays Method for Determining Glucose Yield from Enzymatic Saccharification of Biomass at High-Solids Loadings
Authors: Zhang Han , Liu Hao , Sun Jianliang , Mai Mingqian , Fu Shiyu , Xu Xiangyang 
Published: May 2018

Background:
Determination of the accurate mass of glucose generated from high-solids
biomass saccharification is vital but problematic due to the uncertainty of liquid volume and slurry density.

Methods:
Herein, a new multiple-dilution-assays method was established to deduce the accurate glucose
mass from the hydrolyzing biomass slurry.

Results:
This method was applicable for slurries of pretreated corn stover with a solids consistency up
to 30 wt%, showing a high accuracy and good reproducibility. Dryness did not interfere with the accuracy.
Ethanol at a high level, e.g. 10%, caused only a small negative error (<2%). This method can be
used in either single- or fed-batch high-solids biomass saccharification, allowing to quantify the maldistribution
of glucose in the slurry.

Conclusion:
The significant advantage of the present method was that only one single variable, glucose
concentration, was to be determined, rendering it unnecessary to wash the insoluble or to measure the
changing liquid density.

Authors: Liu Meng , Li Guohe , Zhao Xueli , Qi Xiaole , Zhao Shanshan 
Published: May 2018

Background:
Finite element simulation has become an important method for the mechanism
research of metal machining in recent years.

Objective:
To study the cutting mechanism of hardened 45 steel (45HRC), and improve the processing
efficiency and quality.

Methods:
A 3D oblique finite element model of traditional turning of hardened 45 steel based on ABAQUS
was established in this paper. The feasibility of the finite element model was verified by experiment, and the
influence of cutting parameters on cutting force was predicted by single factor experiment and orthogonal
experiment based on simulation. Finally, the empirical formula of cutting force was fitted by MATLAB. Besides,
a lot of patents on 3D finite element simulation for metal machining were studied.

Results:
The results show that the 3D oblique finite element model can predict three direction cutting
force, the 3D chip shape, and other variables of metal machining and the prediction errors of three direction
cutting force are 5%, 9.02%, and 8.56%. The results of single factor experiment and orthogonal
experiment are in good agreement with similar research, which shows that the model can meet the needs
for engineering application. Besides, the empirical formula and the prediction results of cutting force are
helpful for the parameters optimization and tool design.

Conclusion:
A 3D oblique finite element model of traditional turning of hardened 45 steel is established,
based on ABAQUS, and the validation is carried out by comparing with experiment.
The Dynamics of One Way Coupling in a System of Nonlinear Mathieu Equations
Authors: Bernstein Alexander , Rand Richard , Meller Robert 
Published: May 2018

Background:
This paper extends earlier research on the dynamics of two coupled Mathieu equations by introducing nonlinear terms and focusing on the effect of one-way coupling. The studied system of n equations models the motion of a train of n particle bunches in a circular particle accelerator.

Objective:
The goal is to determine (a) the system parameters which correspond to bounded motion, and (b) the resulting amplitudes of vibration for parameters in (a).

Method:
We start the investigation by examining two coupled equations and then generalize the results to any number of coupled equations. We use a perturbation method to obtain a slow flow and calculate its nontrivial fixed points to determine steady state oscillations.

Results:
The perturbation method reveals the existence of an upper bound on the amplitude of steady state oscillations.

Conclusion:
The model predicts how many bunches may be included in a train before instability occurs.
Development and In Vitro Characterization of Paclitaxel Loaded Solid Lipid Nanoparticles
Authors: Nithya R. , Siram K. , Hariprasad R. , Rahman H. 
Published: May 2018

Background:
Paclitaxel (PTX) is a potent anticancer drug which is highly effective
against several cancers. Solid lipid nanoparticles (SLNs) loaded with anticancer
drugs can enhance its toxicity against tumor cells at low concentrations.

Objective:
To develop and characterize SLNs of PTX (PSLN) to enhance its toxicity
against cancerous cells.

Method:

The solubility of PTX was screened in various lipids. Solid lipid nanoparticles
of PTX (PSLN) were developed by hot homogenization method using Cutina HR and Gelucire
44/14 as lipid carriers and Solutol HS 15 as a surfactant. PSLNs were characterized
for size, morphology, zeta potential, entrapment efficiency, physical state of the drug and
in vitro release profile in 7.4 pH phosphate buffer saline (PBS). The ability of PTX to enhance
toxicity towards cancerous cells was tested by performing cytoxicity assay in
MCF7 cell line.

Results:

Solubility studies of PTX in lipids indicated better solubility when Cutina HR
and Gelucire 44/14 were used. PSLNs were found to possess a neutral zeta potential with
a size range of 155.4 ± 10.7 nm to 641.9 ± 4.2 nm. In vitro release studies showed a sustained
release profile for PSLN over a period of 48 hours. SLNs loaded with PTX were
found to be more toxic in killing MCF7 cells at a lower concentration than the free PTX.
