Full textAbstract:
Combining the modified analytic embedded atom method (MAEAM) with lattice dynamics theory, the phonon dispersion along five symmetry directions have been calculated for three transition metals V, Nb and Ta . A good agreement between calculations and experiments along three high symmetry directions [q00], [qqq] and [qq0] implies that the predicted phonon dispersion along the other two directions [1qq] and [Formula: see text] are well behaved. Along each direction, the phonon frequency decreases for V, Nb and Ta successively may be related to the ratio of the cohesive energy to atomic mass.

Full textAbstract:
Cisanggarung River, a river in West Java Province, often experiences flooding. This study aims to discuss the magnitude of annual flood discharge that may occur in the Cisanggarung watershed. Rain data at each station in the Cisanggarung watershed from 2005 to 2017 were analyzed using descriptive-quantitative methods. Return period flood discharge 2, 5, 10, 20, and 50 years were compared to 2-yearly and monthly flood discharge. The results showed that the data followed the Log-Pearson Type III distribution. The return period flood discharge is: Q2= 181.518 m3/s, Q5 = 242.498 m3/s, Q10 = 283.109 m3/s, Q20 = 316.534 m3/s, Q50 = 373.369 m3/s, Q100 = 412.425 m3/s, Q200 = 452.013 m3/s, dan Q1000 = 546.683 m3/s by using the Nakayasu method. Based on the 2 annual maximum daily rains, 2005, 2007, 2009-2010, 2015, 2009-2017 has the potential to flood Q2, 2012 has the potential to flood Q5, and 2017 has the potential to flood Q10. According to maximum 2-daily monthly rainfall, in 2005-2007, January-April and November have the potential to flood Q2. December has the potential to flood Q10. These results are useful for flood control in the region to be more effective and accurate.

Objectives. To determine how deaths of infants with genetic diagnoses are described in national mortality statistics. Methods. We present a retrospective cohort study of mortality data, obtained from the National Death Index (NDI), and clinical data for 517 infants born from 2011 to 2017 who died before 1 year of age in the United States. Results. Although 115 of 517 deceased infants (22%) had a confirmed diagnosis of a genetic disorder, only 61 of 115 deaths (53%) were attributed to International Classification of Diseases, 10th Revision codes representing congenital anomalies or genetic disorders (Q00-Q99) as the underlying cause of death because of inconsistencies in death reporting. Infants with genetic diagnoses whose underlying causes of death were coded as Q00-Q99 were more likely to have chromosomal disorders than monogenic conditions (43/61 [70%] vs 18/61 [30%]; P < .001), which reflects the need for improved accounting for monogenic disorders in mortality statistics. Conclusions. Genetic disorders, although a leading cause of infant mortality, are not accurately captured by vital statistics. Public Health Implications. Expanded access to genetic testing and further clarity in death reporting are needed to describe properly the contribution of genetic disorders to infant mortality.

What impact has the Brexit on the allocation of money from the structural funds? As the UK is a net contributor to the EU budget, the budget for Structural and Cohesion Policy will shrink. This will have an impact on the allocations of the structural funds to the remaining members of the EU. In order to estimate the allocation of the structural funds to the remaining EU members an allocation model is developed in this article. It appears that the model results do not only show the sharing of the cake, but also the size of it.

The problem of flooding in DKI Jakarta is considered normal because almost every year can hit the city of Jakarta especially during the rainy season. In DKI Jakarta itself there are several rivers, one of which is Ciliwung River which is the most influential river in DKI Jakarta which often cause flood every year. The purpose of this research is to know the location of flood / river flood that occurs in the segments along Ciliwung River STA 7 + 646 s / d STA 15 + 049. Data processing begins with the calculation of average rainfall, frequency analysis, and then hour-time rain distribution. Method of calculation of flood discharge using the synthetic unit of Nakayasu and Gama I synthetic data. Rainfall data using 2 observation stations for 3 years rain (2014-2016). In the frequency analysis used Gumbel distribution berdasrkan test results suitability data Smirnov- Kolmogorov and Chi-Square. The result of flood peak discharge design with HSS Nakayasu on return period Q5 = 687,80 m3 / dt, Q10 = 743,21 m3 / dt, Q20 = 796,36 m3 / s, Q50 = 865,15 m3 / dt, Q100 = 916,71 m3 / s, while flood peak discharge design with HSS Gama I on return period Q5 = 347,03 m3 / s, Q10 = 372,12 m3 / s, Q20 = 396,20 m3 / s, Q50 = 427, 36 m3 / s, Q100 = 450,71 m3 / s. The design flood discharge value approaching the measured debit value is HSS Nakayasu. Steps continued using HEC-RAS 4.1.0 software to determine the capacity of river catchment by using Nakayasu discharge. After analyzing using the software, most stationing of the Ciliwung River at STA 7 + 646 to STA 15 + 049 can not accommodate the planned discharge during the 20th anniversary period, hence the need for river improvements in the form of river normalization and elevation of dikes.

Many studies have shown that land use changes in watersheds such as forests that convert to settlements, industrial and estates, have an impact on flooding. So it is important to know the correlation between the various land use changes to the discharge within a watershed. This study is a preliminary study in an attempt to assess the correlation between land cover index and peak discharge, with case studies in the Beringin River Basin.The peak discharge with the return period of 2, 5, 10, 20, 50 and 100 years are computed with HEC-HMS software, developed by Hydrologic Engineering Centre (HEC) and US Army Corps of Engineers which computes the runoff discharge from the precipitation. As for land covered index (LCI), it is defined as the sum of the land-use index (LUI). The result of the case study shows the strong correlation between the land covered index with the the runoff discharge with such relation : Q100 = -22.42LCI2 + 214.30LCI - 10.62, Q50 = -18.33LCI2 + 181.87LCI - 20.19, Q20 = -14.30LCI2 + 145.27LCI - 15.61, Q10 = -11.36LCI2 + 118.41LCI - 12.29, Q5 = -8.42LCI2 + 91.27LCI - 8.9 and Q2 = -4.44LCI2 + 53.54LCI - 4.5.

A protocol with a high rate of transformation and regeneration of `Hibush' eggplant (Solanum melongena L.) has been developed. This protocol used leaves of in vitro-grown seedlings as a source of explants. The shoot regeneration culture medium contained 0.1 μm thidiazuron (TDZ) combined with 10 to 20 μm N6-[isopentyl] adenine (2iP). Adding TDZ significantly improved regeneration efficiency and produced a mean of 15 buds and 3 to 4 shoots per explant. When explants were cocultivated with Agrobacterium tumefaciens strains Q10, Q20, Q30, Q40, Q201, Q202, Q203, or Q204 containing the native cryIIIB Bacillus thuringiensis (Bt), neomycin phosphotransferase (NPTII), and β-glucuronidase (uidA) genes, a callus/bud regeneration frequency of 38.8% was observed on the selection medium. Kanamycin at 50 μg·mL-1 was most effective in selecting for transgenic buds and shoots. Augmentin at 300 μg·mL-1 was used to eliminate A. tumefaciens. Augmentin also enhanced shoot proliferation. A transformation/regeneration efficiency of 20.8% was observed for shoot production. More than 400 putative transgenic plants have been produced with this method. From 50 putative transgenic plants, gene integration has been confirmed with Southern blot analysis and progeny tests.

The Cikapundung River is one of the rivers that divides the city of Bandung and is often used as the main drainage center of the city, the flow of sewage or waste, tourism objects, and raw water sources. This causes the importance of observing reliable discharge values flowing on the Cikapundung River. In this study the authors analyzed the availability of minimum river discharge in Cikapundung Hulu Sub Das using the FJ Mock method. This study uses rainfall data and climatology data. The rainfall data used are rainfall data from Dago Pakar station and Meteo Lembang station, with a span of 10 years while the climatological data used is data from the Bandung Geophysical Station with a span of 10 years. Mainstay discharge calculated using the F.J Mock Method, where in the F.J Mock calculation there are a number of parameters assumed. This modeling test process is by calibrating the parameters assumed by Trial and Error. The average discharge magnitude for Q50, Q80, Q90, and Q95 in calculating the mock model in the period 2008 to 2014 resulted in a value of 3.87 m³ / sec; 2.98 m³ / sec; 2.46 m³ / sec; and 2.21 m³ /sec. While the discharge values of Q50, Q80, Q90, and Q95 in the observation debit produce successive values of 3.85 m³ / sec; 2.45 m³ / sec; 2.05 m³ / sec; and 1.91 m³ / sec. Even with the increase in the calculation period, reliable debit values have a tendency to rise.

We sought to assess whether coenzyme Q10 (CoQ10) benefits the chronic multisymptom problems that affect one-quarter to one-third of 1990–1 Gulf War veterans, using a randomized, double-blind, placebo-controlled study. Participants were 46 veterans meeting Kansas and Centers for Disease Control criteria for Gulf War illness. Intervention was PharmaNord (Denmark) CoQ10 100 mg per day (Q100), 300 mg per day (Q300), or an identical-appearing placebo for 3.5 [Formula: see text] 0.5 months. General self-rated health (GSRH), the primary outcome, differed across randomization arms at baseline, and sex significantly predicted GSRH change, compelling adjustment for baseline GSRH and prompting sex-stratified analysis. GSRH showed no significant benefit in the combined-sex sample. Among males (85% of participants), Q100 significantly benefited GSRH versus placebo and versus Q300, providing emphasis on Q100. Physical function (summary performance score, SPS) improved on Q100 versus placebo. A rise in CoQ10 approached significance as a predictor of improvement in GSRH and significantly predicted SPS improvement. Among 20 symptoms each present in half or more of the enrolled veterans, direction-of-difference on Q100 versus placebo was favorable for all except sleep problems; sign test 19:1, [Formula: see text]) with several symptoms individually significant. Significance for these symptoms despite the small sample underscores large effect sizes, and an apparent relation of key outcomes to CoQ10 change increases prospects for causality. In conclusion, Q100 conferred benefit to physical function and symptoms in veterans with Gulf War illness. Examination in a larger sample is warranted, and findings from this study can inform the conduct of a larger trial.

This study investigates whether corporate social responsibility (CSR) affects the financial performance of the United States (US) companies. In particular, the impact of CSR on financial performance is investigated in terms of involvement in socially responsible initiatives instead of outcome. The Environmental, Social and Governance disclosure score as calculated by Bloomberg is used as a proxy for corporate involvement in socially responsible initiatives. Fixed effects regression is employed to estimate the relationship between the extent of corporate social disclosure (CSD) and financial performance using the data of listed companies on the Standard &amp; Poor’s 500 during the period 2009-2013. The results suggest that the involvement in socially responsible initiatives has a significantly positive effect on financial performance. In addition, the control variables, such as total compensation to directors, CEO duality and women presence on board are statistically significant to financial performance. It is important to incorporate a longer period in order to validate the positive relationship between CSR and financial performance, whilst the sample is focused on large in size US companies. This study chose to approach the topic from a different angle in order to provide an alternate perspective on this issue taking into account the involvement of socially responsible initiatives via CSD.

Kabupaten Garut khususnya Kawasan Kota Garut merupakan daerah dengan potensi bencana banjir yang tinggi. Kawasan Garut masih dinyatakan sebagai daerah rawan bencana. Hal tersebut berdasarkan hasil laporan dari Badan Penanggulangan Bencana Daerah (BPBD) Kabupaten Garut. Kawasan Kota Garut dilalui oleh Sungai Cimanuk yang berhulu di Pegunungan Mandalagiri di Kabupaten Garut mengalir ke dan bermuara di Laut Jawa di Kabupaten Indramayu.
Pada tanggal 21 September 2016, Garut mengalami banjir bandang yang banyak menyebabkan korban jiwa. Banjir yang menimpa Kota Garut disebabkan oleh buruknya kondisi DAS Cimanuk, dikarenakan alih fungsi tata guna lahan. Selain upaya struktural, kerusakan dan kerugian dapat diminimalisir dengan upaya nonstruktural yaitu peringatan dini banjir.
Peringatan dini banjir pada penelitian ini melakukan analisis banjir menggunakan pemodelan hidrologi dan hidrolika, dimana analisis hidrologi dilakukan di DAS Cimanuk Hulu mulai dari Kecamatan Cikajang Kabupaten Garut, hingga batas daerah genangan Waduk Jatigede di Kecamatan Wado Kabupaten Sumedang. Analisis hidrolika dilakukan mulai Bendung Cimanuk di Kecamatan Bayongbong hingga Bendung Copong di Kecamatan Garut Kota.
Hasil analisis berdasarkan kala ulang 2, 5, 10, 25, 50 dan 100 tahun menunjukan bahwa debit banjir Q5, Q10, Q25, Q50 dan Q100 berpotensi menimbulkan bencana banjir di 9 desa atau 6 kecamatan yaitu Kecamatan Bayongbong, Cisurupan, Cilawu, Garut Kota, Tarogong dan Banyuresmi. Waktu tempuh desa yang berada di luar Kawasan Kota Garut adalah Desa Bayongbong dan Desa Cilea di Kecamatan Bayongbong yaitu 0.1 jam (6 menit) jika banjir terjadi dengan Q ≥ Q50 tahun. Untuk desa yang berada di dalam Kawasan Kota Garut adalah Desa Sukakarya dan Desa Cisurupan di Kecamatan Bayongbong, yaitu 1.5 jam (90 menit) jika banjir terjadi dengan Q ≥ Q50 dan Q100 tahun.

Full textAbstract:
Absorption and magnetic circular dichroism (MCD) spectra are reported for the metallophthalocyanine-N-isologs: magnesium-3,4-pyridinoporphrazine (MgPcN4(−2)), zinc-3,4-pyridinoporphyrazine (ZnPcN4(−2)), and zinc-3,4-pyridazinoporphyrazine (ZnPcN8(−2)). Band deconvolution calculations, which couple both the absorption and the MCD spectra, are reported for each complex. The presence of the peripherally fused pyridine rings in MgPN4(−2) and ZnPcN4(−2) reduces the molecular symmetry and splits the degenerate Q band into its x and y components with zero field splitting parameters (ΔQxy) of 224 and 279 cm−1, respectively. Band fitting results for ZnPcN8(−2) show that with the fused pyridazine rings the degeneracy in the 1Eg excited state is retained and the MCD envelope in the region of the Q00 transition can be described by an MCD A term. Comparison of the fitted band energies with the results reported for ZnPc(−2) (T. Nyokong, Z. Gasyna, and M.J. Stillman. Inorg. Chem. 26, 1087 (1987)) and MgPc(−2) (E.A. Ough, T. Nyokong, K.A.M. Creber, and M.J. Stillman. Inorg. Chem. 27, 2725 (1988)) shows that as the number of nitrogens substituted increases from 0 to 8, the Q band blue shifts from 671 nm in ZnPc(−2) to 664 nm in ZnPcN4(−2) (midpoint between the x and y components) to 654 nm in ZnPcN8(−2) and from 672 nm in MgPc(−2) to 666 nm in MgPcN4(−2) (midpoint). These results demonstrate that chemical modification (symmetric and asymmetric) of the peripherally fused benzene rings influences both the energy and the symmetry of the states that form the inner 18-π-electron system.

Full textAbstract:
Kainic acid (KA) has been used to study the neurotoxicity induced after status epilepticus (SE) due to activation of excitatory amino acids with neuronal damage. Medicinal plants can protect against damage caused by KA-induced SE; in particular, organic extracts of Heterotheca inuloides and its metabolite quercetin display antioxidant activity and act as hepatoprotective agents. However, it is unknown whether these properties can protect against the hyperexcitability underlying the damage caused by KA-induced SE. Our aim was to study the protective effects (with regard to behavior and antioxidant activity) of administration of natural products methanolic (ME) and acetonic (AE) extracts and quercetin (Q) from H. inuloides at doses of 30 mg/kg (ME30, AE30, and Q30 groups), 100 mg/kg (ME100, AE100, and Q100 groups), and 300 mg/kg (ME300, AE300, and Q300 groups) against damage in brain regions of male Wistar rats treated with KA. We found dose-dependent effects on behavioral and biochemical studies in the all-natural product groups vs. the control group, with decreases in seizure severity (Racine’s scale) and increases in seizure latency (p<0.05 in the ME100, AE100, Q100, and Q300 groups and p<0.01 in the AE300 and ME300 groups); on lipid peroxidation and carbonylated proteins in all brain tissues (p<0.0001); and on GPx, GR, CAT, and SOD activities with all the treatments vs. KA (p≤0.001). In addition, there were strong negative correlations between carbonyl levels and latency in the group treated with KA and in the group treated with methanolic extract in the presence of KA (r=‐0.9919, p=0.0084). This evidence suggests that organic extracts and quercetin from H. inuloides exert anticonvulsant effects via direct scavenging of reactive oxygen species (ROS) and modulation of antioxidant enzyme activity.

Shallot is the strategic horticulture commodity and one of superior national commodities. Ministry of Agriculture initiated a pilot project for the development of a corporate based shallot farming business area in Ngantang dan Pujon Districs, Malang Regency. This research aims to analyze the sustainability of the shallot farming in Ngantang and Pujon Districts, Malang Regency. Multidimensional Scaling (MDS) RAP-Shallot's analysis with five dimensions (ecological, economic, social, institutional, and technological) was used with a total of 49 attributes. The results of the sustainability index analysis show that the institutional, technological, and social dimensions are classified as quite sustainable, but the ecological and economic dimensions are still classified as less sustainable. Some attributes that are sensitive to the sustainability of shallot farming include integrated pest and disease control, marketing access of shallots, conflicts related to farming, the role of the middleman in harvest collecting, and the use of high quality and certified bulb. To improve the sustainability of shallot farming, the supervision and management of each attribute must be carried out optimally and integrated with many stakeholders such as farmers, traders, cooperatives, and the government.JEL Classification: Q01; Q02; Q20

1. Neuronal responses to tones and transient stimuli were mapped with microelectrodes in the primary auditory cortex (AI) of barbiturate anesthetized cats. Most of the dorsoventral extent of AI was mapped with multiple-unit recordings in the high-frequency domain (between 5.8 and 26.3 kHz) of all six studied cases. The spatial distributions of 1) sharpness of tuning measured with pure tones and 2) response magnitudes to a broadband transient were determined in each of three intensively studied cases. 2. The sharpness of tuning of integrated cluster responses was defined 10 dB above threshold (Q10 dB, integrated excitatory bandwidth). The spatial reconstructions revealed a frequency-independent maximum located near the center of the dorsoventral extent of AI. The sharpness of tuning gradually decreased toward the dorsal and ventral border of AI in all three cases. 3. The sharpness of tuning 40 dB above response threshold was also analyzed (Q40 dB). The Q40 dB values were less than one-half of the corresponding Q10 dB value. The spatial distribution showed a maximum in the center of AI, similar to the Q10 dB distribution. In two out of three cases, restricted additional maxima were recorded dorsal to the main maximum. Overall, Q10 dB and Q40 dB were only moderately correlated, indicating that the integrated excitatory bandwidth at higher stimulus levels can be influenced by additional mechanisms that are not active at lower levels. 4. The magnitude of excitatory responses to a broadband transient (frequency-step response) was determined. The normalized response magnitude varied between less than 1% and up to 100% relative to a characteristic frequency (CF) tone response. The step-response magnitude showed a systematic spatial distribution. An area dorsal to the Q10 dB maximum consistently showed the largest response magnitude surrounded by areas of lower responsivity. A second spatially more restricted maximum was recorded in the ventral-third of each map. Areas with high-transient responsiveness coincided with areas of broad integrated excitatory bandwidth at comparable stimulus levels. 5. The distribution of excitation produced by narrowband and broadband signals suggest that there exists a clear functional organization in the isofrequency domain of AI that is orthogonal to the main cochleotopic organization of the AI. Systematic spatial variations of the integrated excitatory bandwidth reflect underlying cortical processing capacities that may contribute to a parallel analysis of spectral complexity, e.g., spectral shape and contrast, at any given frequency.(ABSTRACT TRUNCATED AT 400 WORDS)

Background: Quercetin is a flavonoid widely found in plant kingdom and target of studies in pharmacological area due to its potent antinociceptive effect compared to analgesics used in conventional therapies. The aim was to evaluate its antinociceptive activity and antinociception mechanism. Methods: For this, 40 Norvegicus Wistar rats were used, divided into 4 groups: Q50 (treated with quercetin 50 mg/Kg), Q100 (treated with quercetin 100 mg/Kg), Q500 (treated with quercetin 500 mg/Kg) and Positive control (PC) without quercetin treatment), who were submitted through the pain induction methods by tail immersion and formalin in the first step to assess antinociceptive action and in the second step, tail immersion method receiving antagonists from opioid, cholinergic and nitric oxide - L-arginine to evaluate the action mechanism. Results: Quercetin antinociceptive activity was verified at the dose of 50 mg/kg and 100 mg/kg in tail immersion test after formalin injection, with better performance at the dose of 50 mg/kg. There were no statistically significant results in paw opening and capsaicin tests. Quercetin demonstrated a possible influence on opioid and cholinergic pathway, which was not observed on the nitric acid - L-arginine pathway in view of parameters tested. Conclusion: Quercetin performed the best antinociceptive activity at a dose 50 mg/kg and there was a possible influence on opioid and cholinergic pathways.

Este trabalho apresenta um estudo da recarga no Sistema Aquífero Serra Geral (SASG) no Paraná. A estimativa foi realizada através da separação do escoamento de base utilizando o Filtro de Eckhardt. Três métodos diferentes foram utilizados para calcular o parâmetro BFImax: Filtro Inverso, Razão Q90/Q50 e ponderação dos valores pré-definidos por Eckhardt, cujos valores obtidos e comparados para cada bacia que abrange o SASG no Paraná. Os valores de recarga obtidos variaram de 156,89 mm/ano a 489 mm/ano, com médias calculadas por Filtro Inverso, Razão Q90/Q50 e Eckhardt Ponderado foram de 355,59 mm/ano, 352,08 mm/ano e 293,81 mm/ano, respectivamente. Os resultados de BFImax sugerem que os valores pré-definidos por Eckhardt para aquíferos fraturados subestimam a recarga em aquíferos vulcânicos. Os valores das taxas de recarga obtidos apresentaram correlação com valores de declividade e tipo de solo na bacia, entretanto, não apresentaram relação com o tipo aquífero (sedimentar ou fraturado). As taxas mais altas foram identificadas em regiões de menor declividade e com ocorrência de latossolo. Estes resultados podem contribuir para uma gestão adequada das águas subterrâneas no Paraná, entretanto, novos estudos são necessários para a validação.

Abstract. Watershed topography plays an important role in determining the spatial heterogeneity of ecological, geomorphological, and hydrological processes. Few studies have quantified the role of topography in various flow variables. In this study, 28 watersheds with snow-dominated hydrological regimes were selected with daily flow records from 1989 to 1996. These watersheds are located in the Southern Interior of British Columbia, Canada, and range in size from 2.6 to 1780 km2. For each watershed, 22 topographic indices (TIs) were derived, including those commonly used in hydrology and other environmental fields. Flow variables include annual mean flow (Qmean), Q10 %, Q25 %, Q50 %, Q75 %, Q90 %, and annual minimum flow (Qmin), where Qx % is defined as the daily flow that occurred each year at a given percentage (x). Factor analysis (FA) was first adopted to exclude some redundant or repetitive TIs. Then, multiple linear regression models were employed to quantify the relative contributions of TIs to each flow variable in each year. Our results show that topography plays a more important role in low flows (flow magnitudes ≤ Q75 %) than high flows. However, the effects of TIs on different flow magnitudes are not consistent. Our analysis also determined five significant TIs: perimeter, slope length factor, surface area, openness, and terrain characterization index. These can be used to compare watersheds when low flow assessments are conducted, specifically in snow-dominated regions with the watershed size less than several thousand square kilometres.

Rainfall-discharge simulation is a process transformation from rainfall to discharge in a catchment area by modelling. The most popular models are Mock method and NRECA method. It is according to the handbook of irrigation that is written by government (Indonesia). GR2M (Global Rainfall-Runoff Model) is a new model that is not usual to be used in Indonesia. GR2M is a simulation model that needs less parameter than Mock and NRECA methods. This research was conducted in the Bah Bolon catchment area, Simalungun, North Sumatra. It will analyze the simulation of rainfall-discharge by three methods, Mock, NRECA, and GR2M without considering whether the watershed was wet or dry watershed. The analysis was computed the dependable discharge by flow duration curve (fdc) in a series data on each method. The parameter that compared was the dependable discharge, i.e. the discharge with probability 70% (Q70), probability 80% (Q80), and probability 90% (Q90). GR2M will compared with Mock, then compared with NRECA. The results show that the discharge simulation by GR2M methods and the discharge simulation by Mock method has correlation 0.968. The discharge simulation by GR2M method and the discharge simulation by NRECA method has correlation 0,955. It means that GR2M close to the both of them, but GR2M can used easily because it has less parameter than the other. Based on the graphic, GR2M close to the Mock method for probability more than 50%. So, if the probability is 70%, 80%, and 90%, then GR2M method close to Mock method.

Full textAbstract:
One dimensional flow is often used as a flood simulation for the planning capacity of the river. Flood is a type of unsteady non-uniform flow, that can be simulated using HEC-RAS. HEC-RAS software is often used for flood modeling with a one-dimensional flow method. Unsteady flow modeling results in HEC-RAS sometimes refer to error and warning due to unstable analysis program. The stability program among others influenced bend in the river flow, the steep slope of the river bottom, and changes in cross-section shape. Because the flood handling required maximum discharge and maximum flood water level, then a steady flow is often used as an alternative to simulate the flood flow. This study aimed to determine the advantages and disadvantages of modeling unsteady non-uniform and steady non-uniform flow. The research location in the Kanal Banjir Barat, in the Semarang City. Hydraulics modeling uses HEC-RAS 4.1 and for discharge the plan is obtained from the HEC-HMS 3.5. Results of the comparison modeling hydraulics the modeling of steady non-uniform flow has a tendency water level is higher and modeling of unsteady non-uniform flow takes longer to analyze. Results of the comparison the average flood water level maximun is less than 15% (± 0,3 meters), that is 0.27 meters (13.16%) for Q50, 0.25 meters (11.56%) for Q100, dan 0.16 meters (4.73%) for Q200. So the modeling steady non-uniform flow can still be used as a companion version the modeling unsteady non-uniform flow.

Full textAbstract:
Daily flow data from 1964 to 2015 of Budhigandaki River at Arughat were analyzed to assess the impact of flow variation at different time scales to the run of the river (RoR) type of hydropower projects. The data show very high inter-annual variation in daily, monthly and seasonal flows. The long term annual average flow at Arughat was 160 m3/s and varies from 120 to 210 m3/s. The long-term averages of loss in flow for both dry and wet seasons based on daily flows for three design discharges (Q90, Q60 and Q40) were found to be respectively -0.72, -1.76 and -1.54 m3/s for dry season and 0.0, -0.27 and -2.26 m3/s for wet season. Although long-term average loss is small, uncertainty increases with the increase in design discharge. The long-term dry season power loss is about 3 % for the RoR projects of the basin however, its annual variation is large. There is a probability of losing the quantum of energy generation by nearly 40% in some years and gaining by about 30 % in some other years in dry season. The impact of flow variation on power production was negative in both dry and wet seasons for RoR projects of Budhigandaki basin. This study concludes that uncertainty arising from daily flow variation should be assessed while estimating energy generation in hydropower projects. Intra-annual flow variation is, thus, to be taken into consideration while calculating the power generated by the RoR plants; and it should be reflected in power purchase agreement.

According to the World Health Organization, the number of children with physical and mental disabilities accounts for about 3% of the total number of children, as there are about 200 million children with disabilities worldwide. The purpose of the study was to present an analysis of childhood disability in Azerbaijan based on official statistics of mandatory medical examinations conducted in 2014-2019, with calculated prevalence, dynamics, and structure of general and primary disability by age groups. Materials and methods. The study showed that between 2014 and 2019, the number of children with disabilities in Azerbaijan increased by 14% (10,119 people). As for the total structure of the child population, the number of children with disabilities fluctuates between 2.4 and 2.7%. The child disability prevalence rate increased from 246.7 per 10,000 children of the said age in 2014 to 278.3 in 2019. Results. Analysis by age groups shows that the proportion of 0-13-year-olds and 14-17-year-olds in 2014 through 2019 remains unchanged, namely 86% and 14%, respectively. Among children with disabilities, the number of boys (52-54%) exceeds that of girls (46-48%). The age structure of primary childhood disability is dominated by children aged 8-13 years (32%). The decrease of primary disability rates for the period under study occurs throughout all age groups except for the age group of 8-13 years old. The number of children with disabilities aged 0-3 years decreased by 22.7%, 4-7 years by 30%, and 14-17 years by 17.8% during 2014-2019 period. The analysis of primary disability dynamics shows 22% decrease in the total number of children with disabilities registered with medical and social expert assessment institutions for the first time; the largest drop occurred in the categories of circulatory diseases (7-fold), tuberculosis, and respiratory diseases (3-fold). During the research period, an increase of primary disability occurred in diseases of the endocrine system (by 21%), congenital anomalies (malformations) (by 28%), psychiatric/behavioral disorders (by 41%), and diseases of the ear and its appendages (by 34%). Conclusion. The structure of primary morbidity categories causing primary disability in children is dominated by the following major groups of diseases: disorders of the nervous system (G00-G99) accounting for between 9% and 18% in 2014-2019; congenital anomalies (malformations), deformations, and chromosomal disorders (Q00-Q99) accounting for 11-17%, and psychiatric/behavioral disorders (F00-F99) that accounted for 11-18% of the total number of children with disabilities registered with medical and social expert assessment institutions for the first time

A study of 8 nearby spiral galaxies (NGC 2903, 3079, 3198, 3628, 4303, 4321, 4656 and 6946) is carried out using the radio continuum (RC) and far infrared (FIR) images at 1′ resolution. These images are used to study the radial gradients in the ratios of FIR to RC (Q60 and Q100), warm dust temperature (Td(60/100)) etc. The main results are illustrated with NGC 2903 as an example in Fig. 1, where azimuthally averaged quantities are plotted. Td(60/100) decreases away from the center (45–25 K), increasing again by ∼ 5 K in outer galaxies. Typically Q60 decreases by a factor of three away from the center in a given galaxy, but has an order of magnitude spread in the pixel values over all the galaxies. In contrast, Q100 shows flatter gradient, which is expected from the observed temperature gradient. 20 cm RC emission profile is also shown in Fig. 1. The RC and FIR profiles can be fitted by a combination of central gaussian and exponential disk components. In general RC and FIR have about the same fraction of exponential component with the exception of NGC 3628, in which the FIR is dominated by the gaussian while the RC is mostly disk component (see Fig. 2). In 5 of the remaining 7 galaxies, the exponential component contributes > 50% of the total. In general RC scale lengths are larger than the FIR.

Full textAbstract:
Five hydrologically based instream flow assessment methods are compared for 70 rivers in Atlantic Canada; these methods included (i) Tennant method; (ii) 25% mean annual flow (25% MAF); (iii) median monthly flow (Q50) which includes the aquatic base flow (ABF); (iv) the flow equalled or exceeded 90% of time on a monthly flow duration curve (Q90); and (v) the statistical 7-day low flow frequency of a 10-year recurrence interval (7Q10). By comparing the different methods relative to the 25% MAF (the commonly used method in Atlantic Canada), we found that the Q90 and 7Q10 methods predicted extremely low instream flows during winter and summer months. Resource management decisions based on these extremely low flow predictions could have serious adverse consequences. The median monthly flow method (Q50) was recommended for gauged basins, whereas the Tennant method, the 25% MAF method, and the ABF methods were recommended for ungauged basins. For ungauged basins, we conducted a regional study to estimate the 25% MAF and the ABF using multiple regression analysis. Physiographic parameters were used as explanatory variables in the regression analysis. Based on the coefficient of determination, R2, the best regression results were obtained for the 25% MAF with R2 ranging from 0.957 to 0.999. Although the results for ABF were slightly lower than for the 25% MAF, R2 was still in the range of 0.868 to 0.979. Key words: environmental assessment, maintenance flow, low flow, aquatic resources.

Tataguna lahan di Sub Daerah Aliran Sungai (DAS) Banjaran telah mengalami perubahan yang cukup tinggi selama kurun waktu 1995 sampai 2001. Lahan sawah berkurang 1.759,28 hektar menjadi 1.603,97 hektar, tegalan berkurang 289,54 hektar menjadi 283,32 hektar dan permukiman bertambah 1.284,36 hektar menjadi 1.445,88 hektar. Alih fungsi lahan ini mengakibatkan banjir sering terjadi. Beberapa kali Sungai Banjaran meluap menyebabkan banjir di permukiman dan ruas jalan. Kajian pengaruh perubahan lahan terhadap debit banjir perlu dilakukan sehingga peningkatan debit banjir dapat dikendalikan.Tujuan penelitian ini menganalisis debit banjir secara periodik sesuai dengan perubahan tata guna lahan yang terjadi berdasarkan data hidrologi dan parameter DAS. Perhitungan debit banjir dilakukan dengan kalibrasi Environmental Protection Agency – Storm Water Management Model( EPA-SWMM), yaitu metode Hidrograf Observasi (debit terukur) yang dikalibrasi dengan metode Nash. Analisis perubahan lahan menggunakan peta tataguna lahan tahun 2005, Citra Satelit Quick Bird tahun 2010 dan 2014 yang berbasis Geography Information System (GIS). Penggunaan citra satelit resolusi tinggi Quick Bird memenuhi ketepatan dalam menentukan daerah impervious dan pervious sertamorfometri DAS sebagai parameter utama dalam input EPA-SWMM. Model yang telah terkalibrasi digunakan untuk simulasi debit rencana sampai periode ulang 50 tahun.Perubahan lahan selama tahun 2005-2014 permukiman meningkat sebesar 10,98 ha (2,39 %), luas hutan menurun 1,67 ha (0,07%), telah mengakibatkan kenaikan debit banjir Q2 sampai Q50 tahun. Besarnya debit dan kenaikannya berturut-turut sebagai berikut : Q2 tahun sebesar 3,08 m3/dtk (2,16 %), Q5 tahun sebesar 3,5 m3/dtk (1,87 %), Q10 tahun sebesar 3,72 m3/dtk (1,7 %), Q25 tahun sebesar 3,94 m3/dtk (1,60 %) dan Q50 tahun sebesar 4,13 m3/dtk (1,50 %). Volume banjir terjadi peningkatan yakni: Q2 tahun sebesar 0,57 % (10. 106 ) liter, Q5 tahun sebesar 0,45 % (12.106 ) liter, Q10 tahun sebesar 0,42 % (13. 106) liter, Q25 tahun sebesar 0,33 % (12.106) liter dan Q50 tahun sebesar 0,35 % (14.106) liter. Usaha pengendalian banjir pada periode ulang 50 tahun (Q50) yang disimulasikan mampu menurunkan debit banjir antara lain : penegakkan hukum sebesar 14,43 m3/dtk (5 %), embung sebesar 20,9 m3/dtk (7,1 %) dan sumur resapan sebesar 31,18 m3/dtk (10,73 %). Skenario RTRW sebesar 26,3 m3/dtk (9,05 %), kombinasi sumur resapan dan penegakan hukum sebesar 45,92 m3/dtk (15,81 %) dan kombinasi embung dan penegakan hukum sebesar 40,58 m3/dtk (13,97 %). Dari hasil simulasi diperoleh pembuatan sumur resapan, kombinasi sumur resapan dan penegakan hukum, kombinasi embung dan penegakan hukum mampu menurunkan debit banjir sampai pada Q25

The effect of insecure ownership on ordinary investment and natural resource use is examined. Insecure ownership is postulated to depend on the type of government regime in power and the prevalence of political violence or instability. The political determinants of economywide investment are estimated from cross-country data, and the results are used to form an index of ownership security. When introduced into empirical models of natural resource use, this index has a significant and quantitatively important effect on the use of forests and petroleum. Contrary to conventional wisdom, ownership risk slows resource use in some circumstances. (JEL Q20, Q30, E22)

Abstract. Climate change impacts on hydrological processes should be simulated for river basins using validated models and multiple climate scenarios in order to provide reliable results for stakeholders. In the last 10–15 years climate impact assessment was performed for many river basins worldwide using different climate scenarios and models. Nevertheless, the results are hardly comparable and do not allow to create a full picture of impacts and uncertainties. Therefore, a systematic intercomparison of impacts is suggested, which should be done for representative regions using state-of-the-art models. Our study is intended as a step in this direction. The impact assessment presented here was performed for three river basins on three continents: Rhine in Europe, Upper Niger in Africa and Upper Yellow in Asia. For that, climate scenarios from five GCMs and three hydrological models: HBV, SWIM and VIC, were used. Four "Representative Concentration Pathways" (RCPs) covering a range of emissions and land-use change projections were included. The objectives were to analyze and compare climate impacts on future trends considering three runoff quantiles: Q90, Q50 and Q10 and on seasonal water discharge, and to evaluate uncertainties from different sources. The results allow drawing some robust conclusions, but uncertainties are large and shared differently between sources in the studied basins. The robust results in terms of trend direction and slope and changes in seasonal dynamics could be found for the Rhine basin regardless which hydrological model or forcing GCM is used. For the Niger River scenarios from climate models are the largest uncertainty source, providing large discrepancies in precipitation, and therefore clear projections are difficult to do. For the Upper Yellow basin, both the hydrological models and climate models contribute to uncertainty in the impacts, though an increase in high flows in future is a robust outcome assured by all three hydrological models.

Full textAbstract:
The flood magnitudes with 25, 50, and 100 years return periods and the environmental flows (Qenv) are of outmost importance in the context of hydraulic and hydrologic design. In this study, 25 watershed characteristics were linked with the aforementioned recurrence intervals, peak discharge values, as well as Qenv for 15 pristine torrential watersheds with more than 10 years of streamflow records in the Rhodopi mountain range with a view to generating regional relationships for the assessment of discharge annual peaks and environmental flows regarding the ungauged torrential watersheds in the region. The Log-Pearson Type III probability distribution was fitted in the discharge annual peaks time series, so as to predict Q25, Q50, and Q100, whereas the Tennant method was utilised so as to estimate the environmental flows magnitude. Similarly, the Kolmogorov–Smirnov and the Anderson–Darling tests were performed to verify the distribution fitting. The Principal Components Analysis method reduced the explanatory variables number to 14, whilst the stepwise multiple regression analysis indicated that the exponential model is suitable for predicting the Q25, the power model best forecasted the Q50 and Q100, whereas the linear model is appropriate for Qenv prognosis. In addition, the reliability of the obtained regression models was evaluated by employing the R2, the Nash–Sutcliffe efficiency, and the Index of Agreement Statistical Criteria, which were found to range from 0.91–0.96, 0.88–0.95 and 0.97–0.99, respectively, thereby denoting very strong and accurate forecasts by the generated equations. Thus, the developed equations could successfully predict the peak discharge values and environmental flows within the region’s ungauged watersheds with the drainage size not exceeding 330 km2.

Kuningan Dam which is located in Kuningan District, West Java has 21,8 km2 watershed area. This dam also acts as a flood control facility which functions supported by the reservoir’s topography and its spillway building. The spillway building releases excess water from the dam into the downstream area. In the downstream part of the spillway, usually, hydraulic jump phenomenon occurs which depends on the flood water level of the river. The hydraulic jump used in the designing process of stilling basin length. The stilling basin in the spillway building generally designed using Q100. The spillway in Kuningan Dam is designed as a closed conduit channel. In this study, the Kuningan Dam spillway is re-designed as an open channel using ogee type spillway. Based on the modeling result, the length of hydraulic jump that occurs when modeled with the return period discharge of Q25 is 21.54 m, Q50 is 16.65 m, and Q100 is 0.98 m. It is seen that in Q25 the jump was the furthest, so an elaborate study regarding hydraulic jump phenomenon and design standards of the spillway is required.

Peristiwa erupsi Gunung Agung yang terjadi akhir tahun 2017 telah berdampak terhadap berbagai hal dan salah satunya terhadap beberapa bangunan pengendali lahar yang ada di sepanjang alur sungai. Beberapa bangunan masih tetap dalam kondisi baik namun beberapa bangunan kondisinya menjadi rusak ringan, rusak sedang bahkan rusak berat sehingga fungsinya tidak bisa seperti semula. Sementara di bagian lainnya inventarisir bangunan yang ada serta evaluasi kinerjanya belum terpetakan dengan baik. Target khusus dari penelitian ini adalah terinventarisasinya bangunan untuk selanjutnya menjadi dasar dalam melakukan evaluasi kinerja yang menjadi data yang sangat penting bagi instansi terkait terutama Balai Wilayah Sungai Bali Penida dalam melakukan operasi dan pemeliharaan bangunan pengendali lahar. Metode penelitian ini menerapkan metode analisis kwantitatif berdasarkan pengumpulan data primer dan skunder baik melalui pengukuran langsung di lapangan maupun dengan studi literatur. Jumlah bangunan pengendali lahar yang terdapat di sepanjang alur Tukad Unda sebanyak 9 buah. Berdasarkan jenis bangunan yang ada maka bangunan tersebut dibagi menjadi 3 buah jenis yaitu Check Dam sebanyak 6 buah dengan 2 buah type lubang dan 4 buah type tertutup, 2 buah jenis konsolidasi Dam dan 1 buah jenis dinding penahan tanah. Berdasarkan analisa hidrologi menunjukkan R2 = 99,56 mm, R5 = 110,56 mm, R10 = 115,21 mm, R25 =127,56 mm, R50 = 138,41mm dan R100 = 141,56 mm. Sementara debit banjir rancangan Q2 = 150,23 m3/dt. Q5 = 165,36 m3/dt. Q10 = 173,47 m3/dt. Q25 = 182,03 m3/dt. . Q50 = 187,29 m3/dt dan Q100 = 192,16 m3/dt. Hasil analisa kapasitas bangunan menunjukkan bahwa semua bangunan mampu melewatkan debit banjir kala ulang 25 tahunan. Ini disebabkan beberapa hal yaitu penampang bangunan yang besar, kemiringan sungai yang tinggi serta kondisi DAS yang masih bagus. Hasil evaluasi teknis kinerja bangunan menunjukkan 8 dari 9 buah bangunan yang ada dalam kondisi yang baik memiliki kinerja diatas 80%. Sementara satu bangunan chek dam mengalami rusak berat karena terbawa hanyut oleh erupsi tahun 2017 yaitu check dam 6 yang terletak di Desa Tangkas.Kata kunci: Bangunan Pengendali Lahar, Gunung Agung, Evaluasi Kinerja Bangunan, Kapasitas, Hidrologi

Alginate based floating in situ gelling systems of famotidine (FIGF) were prepared by dissolving varying concentrations of alginate in deionized water containing sodium citrate, to which varying concentrations of drug and calcium chloride was added and dissolved by stirring. Results of preliminary trials indicate that concentrations of sodium alginate, calcium chloride and sodium citrate affected the characteristics of in situ gel. A 32 full factorial design was employed to study the effect of independent variables, concentration of sodium alginate (X1) and concentration of calcium chloride (X2) on dependent variables, i.e. viscosity, drug content, drug release at 4 hrs (Q50) and drug release at 8 hrs (Q80). A sustained drug release was obtained for more than 8 hrs. In vivo testing of FIGF to albino Wistar rats demonstrated significant anti-ulcer effect of famotidine.

Along the paper, we presented an analysis of changes of cross-sections morphology within the regulated reach of a mountain river. The river engineering works there were done by building cable block ramp. The studied reach was located in the Czarny Dunajec river. Analyzed reach of the river consisted of 100-m long segment upstream of the existing block ramp and 65 m downstream of it. The analysis was done based on field measurements, numerical modeling with HEC-RAS and Hjulström’s graph. Numerical modeling was conducted for observed flood Qfl ood = 16.9 m3·s–1 on 5 August 2013, and for the t-years floods: Q50% = 59 m3·s–1, Q25% = 99 m3·s–1, Q10% = 165 m3·s–1 and Q1% = 321 m3·s–1. For the analyzed reach an attempt was done to determinate dominant discharge.

Floods are seen in countries in tropical climatic zones, both in terms of quantity and harm. The non-tropical climate countries such as Turkey are also affected by the floods. The geographical structure of Turkey is extremely complex and varies even at short distance. Therefore, the shape and effects of the floods vary from region to region. Considering the peculiar state of nature, floods, which are the greatest disasters after the earthquake, are unlikely to occur. But floods are becoming more risky for human beings day by day because of the population growth, need of water and settlements, wrong zoning plan, and unplanned engineering practices. Regulation comes at the beginning of measures to be taken to minimize the damages that occur from the floods. To do these studies, it must be specified the changes which bridges on the rivers and hydraulics structures like regulator cause in cross sections and the effects of the changes to water surface profile due to the natural state of the land. In order to determine water surface profiles, many software packages have been developed for facilitating the analysis and calculation. HEC-RAS is one of them. In this study, the floodplain analysis was handled between Diyarbakır-Silvan Highway and historical Ten-Eyed Bridge. There are three bridges, and one of which are historical bridges, as well as fertile agricultural lands, facilities, and hospitals in the Dicle University campus, the Hevsel Gardens on the UNESCO World Cultural Heritage List, and some residential areas on the route under study. The aim of the study we have done in this much important route is to evaluate the flood areas and create a flood hazard map which can predict risky areas. And also contributing to the Tigris River Rehabilitation Project is one of the aims. About methodology, the 1/1000 maps of the study area were digitized using the AutoCAD Civil 3D program and cross sections were made by obtaining the digital elevation models of the region. The obtained cross sections were defined in the HEC-RAS software, and the hydraulic characteristics of the flood bed and the water surface profiles of the Q25, Q50, Q100, and Q500 flood recurring and one-dimensional floodplain analysis of the Tigris River were determined.
