Gauss-Manin connections for p-adic families of nearly overconvergent modular forms

We interpolate the Gauss-Manin connection in p-adic families of nearly overconvergent modular forms. This gives a family of Maass-Shimura type differential operators from the space of nearly overconvergent modular forms of type r to the space of nearly overconvergent modular forms of type r + 1 with p-adic weight shifted by 2. Our construction is purely geometric, using Andreatta-Iovita-Stevens and Pilloni's geometric construction of eigencurves, and should thus generalize to higher rank groups.Comment: Final version accepted for publication in the Annales de l'Institut Fourier.

Hidroksida Berlapis Ganda ZnCrCI: Kesan Haba Terhadap Luas Perm.ukaan dan Keliangan

ZnCrCI layered double hydroxides, with Zn/Cr ratios (R) 3 and 4 were prepared by a coprecipitation method and heat treated samples were subsequently prepared. Their bulk structure was investigated by X-ray diffraction and surface area techniques. X-ray diffraction analysis showed that the layered double hydroxide phase remained unchanged upon heating up to 250°C for 5 h in an oven at atmospheric pressure. However, new phases, namely spinel-like and ZnO phases appeared when the samples were heated at 350°C and above for the same duration. The specific surface areas decreased with increasing temperature (between 450850° C) for both R values but no trend was observed for temperatures between 250-350°C. Average pore diameter was found to be optimum at 550°C and 450°C for R = 3 and 4, respectively

Analisis Kandungan Logam Berat Timbal dan Kadmium pada Pengolahan Ikan Asin di Kabupaten Banggai Kepulauan: Analysis Of Heavy Metal Content Of Lead (Pb) And Cadmium (Cd) In The Processing Of Salted Fish In The Regency Of Banggai Islands

This study was aimed to determine lead (Pb) and cadmium (Cd) contained in salted fish from Banggai Islands Regency. The sampleswere collected by purposive sampling from Tinangkung district, Liang district and South Totikum district. Pb and Cd content was measured using the atomic absorbtion spectrophotometry method. The results showed that layang salted fish from Tinangkung district had Pb content 0,0976 ± 0,0660 mg/kg and Cd content 0,0064 mg/kg. Lencam salted fish from Liang district had Pb content 0,2459 ± 0,0206 mg/kg and Cd content 0,0255 mg/kg. Cakalang salted fish from South Totikum district had Pb content 0,2100 ± 0,0148 mg/kg and Cd content 0,0254 mg/kg. Salt from Liang district had Pb content 0,3250 ± 0,0071 mg/kg and Cd content 0,1075 ± 0,0071 mg/kg. While the value of Pb and Cd in content salt from South Totikum district had 0,2250 ± 0,0071 mg/kg and 0,1025 ± 0,0035 mg/kg. From the result, could be concluded that salted fish and salt from three different places in Banggai Island Regency are still in limit to consume based on standart from Badan Standart Nasional Indonesia (BSNI) that determine 0,3 mg/kg for lead and 0,1 mg/kg for cadmium

Identifikasi Faktor-Faktor Kerentanan Terhadap Bencana Kebakaran Hutan Dan Lahan Di Kecamatan Liang Anggang Kota Banjarbaru

Fenomena bencana kebakaran hutan dan lahan beserta dampak yang telah ditimbulkan di Kecamatan Liang Anggang Kota Banjarbaru Kalimantan Selatan mengindikasi kurangnya kewaspadaan dan kesiapan menghadapi ancaman bahaya kebakaran hutan dan lahan berpengaruh terhadap meningkatnya kerentanan akan terjadinya bencana kebakaran hutan dan lahan dengan dampak yang lebih besar dan luas. Kerentanan merupakan suatu kondisi masyarakat yang tidak dapat menyesuaikan Perubahan yang disebabkan oleh ancaman tertentu, oleh karena itu perlunya suatu identifikasi terhadap faktor-faktor yang mempengaruhi kerentanan akan terjadinya bencana kebakaran hutan dan lahan. Dalam mencapai tujuan penelitian, dilakukan analisa terhadap faktor-faktor yang berpengaruh terhadap kerentanan (vulnerability) menggunakan analisa skala likert, uji validitas dan reliabilitas dan analisa deskriptif untuk mendapatkan faktor-faktor kerentanan yang berpengaruh terhadap bencana kebakaran hutan dan lahan. Dari penelitian ini didapatkan identifikasi faktor kerentanan yang mempengaruhi bencana kebakaran hutan dan lahan di Kecamatan Liang Anggang Kota Banjarbaru

The e-Index, Complementing the h-Index for Excess Citations

BACKGROUND: The h-index has already been used by major citation databases to evaluate the academic performance of individual scientists. Although effective and simple, the h-index suffers from some drawbacks that limit its use in accurately and fairly comparing the scientific output of different researchers. These drawbacks include information loss and low resolution: the former refers to the fact that in addition to h(2) citations for papers in the h-core, excess citations are completely ignored, whereas the latter means that it is common for a group of researchers to have an identical h-index. METHODOLOGY/PRINCIPAL FINDINGS: To solve these problems, I here propose the e-index, where e(2) represents the ignored excess citations, in addition to the h(2) citations for h-core papers. Citation information can be completely depicted by using the h-index together with the e-index, which are independent of each other. Some other h-type indices, such as a and R, are h-dependent, have information redundancy with h, and therefore, when used together with h, mask the real differences in excess citations of different researchers. CONCLUSIONS/SIGNIFICANCE: Although simple, the e-index is a necessary h-index complement, especially for evaluating highly cited scientists or for precisely comparing the scientific output of a group of scientists having an identical h-index

Electrogenic proton/L-glutamate symport in isolated asparagus sprengeri mesophyll cell

Medium' alkaliniiation occurred -lipon the addition of L-Glu to mechanically isolated Asparagus sprenger-i mesophyll cells suspended in 1 mM CaS04. Alkalinization resulted from the coupled entry of H+ and L-Glu anion into the cells. This H+ IL-Glu symport did not stimulate K+ efflux. K+ efflux has been observed during H~ lamino acid symport in other systems. The stimulation of K+ efflux by proton coupled symport is regarded as an indicator of a plasma membrane depolarizing electrogenic symport process. H+ IL-Glu symport in Asparagus sprengerimesophyl1 cells was investigated to determine whether or not the process was electrogenic. The rate of uptake of 0.25 11M 3H-MTPP+ ( Methyltriphenylphosphonium, methyl-3H ) is a probe for monitoring changes in the membrane potential. 3HMTPP+ uptake was reduced by K+ or CCCP, agents known to depolarize the membrane potential. Uptake of 3H-MTPP+ was also inhibited by L-Glu but not by D-Glu. Conversely, 10 mM external MTPP+ inhibited the uptake of 14C-U-LGlu. Simultaneous measurements of the rates of 14C-U-L-Glu uptake and L-Glu dependent H+ influx showed that the molar stoichiometry of H+ IL-Glu symport was 2 to 1. K+ or Na+ stimulated H+ efflux was completely inhibited by DCCD, DES, oligomycin and antimycin reagents which inhibit ATP driven H+ efflux. The H+ efflux \Vas also stimulate.d by the weak acids, butyric acid and acetic acid, which are known fo-aCidify the cytoplasm. This weak acid stimulated H+ efflux was also completely inhibited by oligomycin. It was calculated that net L-Glu dependent H+ influx increased by 100% in the presence of oligomycin and that despite net medium alkalinization H+ IL-Glu symport stimulates ATP dependent H+ efflux. 11 The data presented in this study indicate that H+ IL-Glu symport is electrogenic. The data also show that ATP dependent Ht efflux rather than K+ efflux is the- process compensating for thi~ electrogenic H+ IL-Glu symport

Photothermal degradation studies

Key reaction intermediates of photooxidation identified and characterized by laser flash Electron Spin Resonance (ESR) spectroscopy were discussed. Effects of temperature and ultraviolet intensity were studied in order to develop meaningful accelerated testing procedures for encapsulant evaluation. In a program to study the failure of Tedlar/ethylene vinyl acetate (EVA)/stainless steel modules, failure modes similar to those observed outdoors in real-time conditions were simulated in accelerated testing. An experimental technique was developed to quantitatively assess the extent of degradation
