Design of The New Upper Structure Comba Bridge in Jayapura Regency Using Prestressed Concrete
Comba Bridge is located in the main road of Jayapura Regency. This bridge has some damages due to the density of the traffic on the bridge. In order to increase the level of service, it is necessary to figure out the solution. One of the solution is designing a new bridge beside the old bridge. The aim is to design a new bridge using prestressed concrete girder as the main structure and figure out the general construction method for this bridge. Stressing method for the main structure is post tensioning method. The new bridge has two 25 meters spans. Designing includes secondary structure design and main structure design. The analysis result show that pedestrian barrier consists of two galvanized steel railing, H-profile steel column, concrete deck slab and pavement slab using reinforced concrete with 22 cm thickness. Main structure using Precast Concrete I Girder (PCI Girder) has 4500 kN initial prestressed force and 4 cables that consist of 7-wire strand super grade. Erection method of the girder using launcher machine
Regulatory T Cells in Human Lymphatic Filariasis: Stronger Functional Activity in Microfilaremics
Infection with filarial parasites is associated with T cell hyporesponsiveness, which is thought to be partly mediated by their ability to induce regulatory T cells (Tregs) during human infections. This study investigates the functional capacity of Tregs from different groups of filarial patients to suppress filaria-specific immune responses during human filariasis. Microfilaremic (MF), chronic pathology (CP) and uninfected endemic normal (EN) individuals were selected in an area endemic for Brugia timori in Flores island, Indonesia. PBMC were isolated, CD4CD25hi cells were magnetically depleted and in vitro cytokine production and proliferation in response to B. malayi adult worm antigen (BmA) were determined in total and Treg-depleted PBMC. In MF subjects BmA-specific T and B lymphocyte proliferation as well as IFN-gamma, IL-13 and IL-17 responses were lower compared to EN and CP groups. Depletion of Tregs restored T cell as well as B cell proliferation in MF-positives, while proliferative responses in the other groups were not enhanced. BmA-induced IL-13 production was increased after Treg removal in MF-positives only. Thus, filaria-associated Tregs were demonstrated to be functional in suppressing proliferation and possibly Th2 cytokine responses to BmA. These suppressive effects were only observed in the MF group and not in EN or CP. These findings may be important when considering strategies for filarial treatment and the targeted prevention of filaria-induced lymphedema
Secondary crystalline phases identification in Cu2ZnSnSe4 thin films: contributions from Raman scattering and photoluminescence
In this work, we present the Raman peak
positions of the quaternary pure selenide compound
Cu2ZnSnSe4 (CZTSe) and related secondary phases that
were grown and studied under the same conditions. A vast
discussion about the position of the X-ray diffraction
(XRD) reflections of these compounds is presented. It is
known that by using XRD only, CZTSe can be identified
but nothing can be said about the presence of some secondary
phases. Thin films of CZTSe, Cu2SnSe3, ZnSe,
SnSe, SnSe2, MoSe2 and a-Se were grown, which allowed
their investigation by Raman spectroscopy (RS). Here we
present all the Raman spectra of these phases and discuss
the similarities with the spectra of CZTSe. The effective
analysis depth for the common back-scattering geometry
commonly used in RS measurements, as well as the laser penetration depth for photoluminescence (PL) were estimated
for different wavelength values. The observed
asymmetric PL band on a CZTSe film is compatible with
the presence of CZTSe single-phase and is discussed in the
scope of the fluctuating potentials’ model. The estimated
bandgap energy is close to the values obtained from
absorption measurements. In general, the phase identification
of CZTSe benefits from the contributions of RS and
PL along with the XRD discussion.info:eu-repo/semantics/publishedVersio
PERLINDUNGAN HUKUM BAGI APOTEKER DALAM PELAKSANAAN KESEHATAN YANG PROFESIONAL DAN MANDIRI DI KABUPATEN ACEH BARAT
This study titled Legal Protection for Pharmacists in the implementation of
professional and independent health in the district of West Aceh. The background
of the research was due to the number of pharmacists who were blamed by certain
parties, where the pharmacist already worked in accordance with the principles
contained in the code of ethics and legislation to their authority. Thus,whst kind
of the form of legal protection can be given to the pharmacists who suffered
losses?
The main issues answered in this paper were what kind of the legal
protection was for pharmacists in the implementation of professionals and
independent health care and what remedies are made by the consumer if the
pharmacist did not run an independent and professional health care in West Aceh
district.
This study was an assessment of the normative-empirical laws, while the
samples in this study were four pharmacists. Sampling technique was done by
purposive sampling. The data were obtained by interviewing the subjects, while
the tool used was the interview guide.
The results of this study indicated that legal protection for pharmacists in
the implementation of professional and independent health was preventive and
repressive, while legal action nu consumers when feeling aggrieved by
Pharmacists was that they could hold accountable for the pharmacist om condition
that the consumer must be able to prove that the fault was purely because of
pharmacists
Dihydro-β-agarofurans from the Australian rainforest plant Denhamia celastroides that inhibit leucine transport in prostate cancer cells
Four new dihydro-β-agarofurans, denhaminols K–N (4–7), along with three known secondary metabolites, denhaminols A–C (1–3) were obtained from the large-scale isolation studies of the leaves of the Australian endemic rainforest plant, Denhamia celastroides. The structures of the previously undescribed compounds were determined by detailed 1D and 2D nuclear magnetic resonance spectroscopy, mass spectrometry, ultraviolet, and infrared data analysis. All compounds were found to inhibit the activity of leucine transport in a human prostate cancer cell line with IC 50 values ranging from 5.1–74.9 μM. Dihydro-β-agarofurans 1–7 showed better potency than the L-type amino acid transporter family inhibitor, 2-aminobicyclo[2.2.1]-heptane-2-carboxylic acid (BCH)
Submarine landslide-induced tsunami generation in Makassar strait, Indonesia using Non-hydrostatic wave model
AbstractTsunami modelling of potential landslide-induced tsunami in Makassar Strait is carried out to quantify possible damage to the nearby cities. The numerical model is used to represent the wave generation by using NHWAVE model. The simulations consist of a series of scenarios based on distinct size of the landslide volume. Four landslides with volume 5, 8, 70, and 200 km3 are used as tsunami sources in the initiation stage. The sources are evenly distributed in the strait addressing different landslide location. Maximum wave heights of 1.5 m are found in the area between Palu and Bangkir from case 1 and around Talok from case 2 simulations. The empirical run-up calculation of 7.5 m is estimated at the land for the presented wave height. The value significantly elevates the case 3 and 4 proportional to the volume values. The waves impact more than half of coastline with maximum value found in the Sulawesi side. Interestingly, wide and narrow shelf next to Kalimantan Island plays an important role in reducing the tsunami hazard level.</jats:p

Synthesis of bilocularin A carbamate derivatives and their evaluation as leucine transport inhibitors in prostate cancer cells
Large-scale extraction of the leaves of the Australian rainforest tree Maytenus bilocularis followed by extensive purification studies afforded the targeted and abundant dihydro-β-agarofuran, bilocularin A, in sufficient quantities (>500 mg) for detailed semi-synthetic chemistry. Eight bilocularin A carbamate analogues were synthesised using a series of commercially available isocyanate reagents in high purity (>95%) and variable yields (9–91%). All previously undescribed analogues were spectroscopically characterised using NMR, UV, IR and MS data. One compound afforded crystalline material and subsequent single crystal X-ray analysis (Cu-Kα) confirmed the chemical structure along with the absolute configuration. All compounds were evaluated for anti-proliferative activity against the human prostate cancer cell line LNCaP; none of the compounds showed significant (>50%) growth inhibition at 20 μM. Compounds were also tested for their ability to inhibit leucine transport in LNCaP cells, and two analogues showed moderate activity with IC50 values of 8.9 and 8.5 μM. This is the first reported synthesis of dihydro-β-agarofuran carbamate derivatives
