Diffusion-Corrected Sigma Using Dual Exponential Fit for Time-Lapse Reservoir Monitoring
Authors: Al-Turkey Shaikha , Freile Daniel , Tagarieva Larisa , Elyas Mohamed , Schmid Gregory
Published: February 2020

Pulsed-neutron capture (PNC) logs are commonly used to determine formation water saturation in cased-hole environments, often for time-lapse monitoring purposes. This paper describes a new diffusion-corrected sigma algorithm developed for a pulse neutron logging tool.

In southeast Kuwait, diffusion-corrected sigma log data was recorded in three wells using an array of four optimally spaced gamma ray detectors above a neutron generator. To calculate a diffusion-corrected sigma, an algorithm based on a dual exponential fit was applied to the time-decay spectrum of the near and far detectors. This calculation separates the formation and borehole decays. This approach provides an apparent formation sigma for the near and far detectors. The algorithm uses the near detector for final sigma, and a diffusion correction to the near sigma is determined by a function of a near-far sigma difference.

The diffusion-corrected sigma matched the expected results and provided a good statistical quality—even at high sigma values—because it is based on the near detector with its higher count rate, as demonstrated in the examples presented. Also, the formation sigma was independent of different borehole conditions in which the data was recorded. The final formation sigma results were compared to volumetric results from open-hole data (volume of shale, effective porosity and water saturation) and sigma calculated from open-hole volumetric using material balance. The PNC data recorded in the three wells allowed determination of the most recent oil-water contact (OWC) and update of water encroachment maps from the time-lapse monitoring. Comparing with previous sigma data recorded in these wells, it was concluded a normalization transform is not needed because R2 value of the linear regression is close to 1.

The diffusion-corrected sigma algorithm using dual exponential fit showed that this technique was able to extract independent values for borehole sigma and formation sigma for each detector and to perform an accurate diffusion correction. This algorithm will provide reliable sigma values regardless of the borehole conditions in which the data was recorded.
Production Allocation of Commingled Reservoir Fluids by On-Site Spectroscopic Analysis

Published: February 2020

Allocation of production fluids is a key aspect for reservoir management purposes. Many consolidated techniques exist, but they have the drawback of being expensive (multiphase flowmeters, production logging tool, spectral noise logging) or not directly portable at wellhead (geochemical production allocation). For these reasons, we developed a new rapid and accurate method employing Fourier Transform InfraRed (FTIR) spectroscopy coupled with regression methods, and successfully applied to a real case of reservoir commingled fluids.

After testing different spectroscopic techniques, we realized that FTIR was the best method to perform allocation. FTIR spectra were acquired with a portable spectrometer operated in transmission mode on oils loaded in standard cells for liquids (0.1 mm optical path, KBr windows). The portable instrumentation yielded equally informative signals as the laboratory one for our needs. After suitable baseline subtraction, a machine learning workflow written in R language was applied to select the most informative spectral regions for the deconvolution of single component contribution in analysis of mixtures. Through a minimization algorithm, we are able to get the concentration of end members samples into the commingled samples.

To validate our technology, we first took the end member oils (coming from two different layers of the same reservoir), we mixed them, performed the IR analysis with our portable instrument and then applied our regression modelling approach, getting results that are both accurate and precise (less than 2% of average error). Based on that, we applied our workflow directly on 9 real commingled samples coming from the same aforementioned reservoir, getting results that are in very good agreement with multi-phase flowmeters measurements.

We then think that the technology is very promising and can be considered a real, low-cost and affordable opportunity among all the reservoir allocation best practices.

Combination of spectroscopic portable IR hardware with regression software for the sake of allocation directly at wellhead is an innovative solution for the old problem of allocation.

Картофель поражается с заметным экономическим ущербом по меньшей мере 54 видами фитопатогенных грибов, 39 видами вирусов, 19 видами нематод, 3 видами фитоплазм и 11 видами бактерий. Бактериальные патогены вызывают болезни различной этиологии: от мокрой гнили до «зебры чипсов». Примерно 8-12 лет назад появились первые сообщения о проникновении и распространении новых возбудителей бактериозов во всех регионах России, в том числе о заболеваниях, вызываемых бактериями родов Dickeya dianthicola, D. solani и Clavibacter michiganensis subsp. michiganensis. В связи с усилением в России вредоносности бактериальных болезней картофеля, вызываемых различными группами бактерий, необходима точная идентификация патогенов, изучение путей их распространения, сохранения и разработка мер борьбы, ограничивающих распространение и обеспечивающих снижение ущерба от бактериальных болезней. Мы оценили распространение бактериальных патогенов картофеля как на основе собственных данных, так и по опубликованным сообщениям.

Potato is affected at least by 54 species of phytopathogenic fungi, 39 viruses, 19 species of nematodes, 3 species of phytoplasmas, and 11 species of bacteria. Bacterial pathogens can cause diseases of different etiology: from "soft rot" to “zebra chips”. About 8-12 years ago, the increased severity of bacterial diseases in regions of Russia was reported, including diseases, caused by bacteria of genus Dickeya and Clavibacter michiganensis subsp. michiganensis. In connection with the increased harmfulness of bacterial diseases of sugar beet in Russia, caused by different groups of bacteria, we need an accurate identification of the pathogens, ways of their distribution, preservation, and search for control measures to limit the spread and reduce the damage from bacterial diseases of potato. We assessed and confirmed the distribution of potato bacterial pathogens based on own data as well as on reported incidence.

Dethioacylation by Sirtuins 1–3: Considerations for Drug Design using Mechanism-based Sirtuin Inhibition
Authors: Rajabi Nima , Lund Nielsen Alexander , Olsen Christian Adam
Published: February 2020

The sirtuin enzymes are potential drug targets for intervention in a series of diseases. Efforts to inhibit enzymes of this class with thioamide- and thiourea-containing, substrate-mimicking entities have produced a number of high-affinity binders. However, less attention has been dedicated to the investigation of the stability of these inhibitors under various conditions. Here, we provide evidence of unprecedented degree of cleavage of short-chain epsilon-N-thioacyllysine modifications meant to target these sirtuins and further provide insights into the serum stability of compounds containing both thioamides and thioureas. Our study questions the utility short-chain thioamide-based inhibitors of sirtuins for drug development and points to application of mono-alkylated thiourea-based chemotypes as more promising for targeting sirtuins 1 and 3, in particular.
Predicting Core Level Photoelectron Spectra of Amino Acids Using Density Functional Theory
Authors: Pi Jo , Stella Martina , Fernando Nathalie , Lam Aaron , Regoutz Anna , Ratcliff Laura
Published: February 2020

Core level photoelectron spectroscopy is a widely used technique to study amino acids. Interpretation of the individual contributions from functional groups and their local chemical environments to overall spectra requires both high-resolution reference spectra and theoretical insights, for example from density functional theory calculations. This is a particular challenge for crystalline amino acids due to the lack of experimental data and the limitation of previous calculations to gas phase molecules. Here, a state of the art multiresolution approach is used for high precision gas phase calculations and to validate core hole pseudopotentials for plane-wave calculations. This powerful combination of complementary numerical techniques provides a framework for accurate ΔSCF calculations for molecules and solids in systematic basis sets. It is used to successfully predict C and O 1s core level spectra of glycine, alanine and serine and identify chemical state contributions to experimental spectra of crystalline amino acids.
Modeling the Effects of O-sulfonation on the CID of Serine
Authors: Lucas Kenneth , Barnes George
Published: February 2020

We present the results of direct dynamics simulations and DFT calculations aimed at elucidating the effect of \textit{O}-sulfonation on the collision induced dissociation for serine. Towards this end, direct dynamics simulations of both serine and sulfoserine were performed at multiple collision energies and theoretical mass spectra obtained. Comparisons to experimental results are favorable for both systems. Peaks related to the sulfo group are identified and the reaction dynamics explored. In particular, three significant peaks (m\z 106, 88, and 81) seen in the theoretical mass spectrum directly related to the sulfo group are analyzed as well as major peaks shared by both systems. Our analysis shows that the m\z 106 peaks result from intramolecular rearrangements, intermolecular proton transfer among complexes composed of initial fragmentation products, and at high energy side-chain fragmentation. The \mz 88 peak was found to contain multiple constitutional isomers, including a previously unconsidered, low energy structure. It was also seen that the RM1 semi empirical method was not able to obtain all of the major peaks seen in experiment for sulfoserine. In contrast, PM6 did obtain all major experimental peaks.

Published: February 2020

To create autonomous microrobots which move in the presence of a constant energy source, their mechanical motion must have a capacity for self-control. This is realized when a structural change occurs with conversion of energy facilitated by cofactors, with a self-regulation component to prevent reaching a static state. Here, we present a single crystal structure analysis of azobenene derivatives which reveals a mille-feuille-like layered structure of sparse and dense layers of six independent azobenzene moieties. In this anisotropic structure, a specific azobenzene molecule acts as a reaction center for a light-to-mechanical function process. The other molecules in the crystal act as modulators. Moreover, depending on the photoisomerisation process activated by a polarized light source, different cyclic motions are observed. We clarify the mechanism by which the self-organized mechanical behavior of these azobenzene molecules is achieved at the molecular level. Thus, the present results demonstrate that autonomously driven molecular materials can exhibit information-responsive and self-sustainable motion by incorporating stimulus-responsive sensors.

Current methods for bioconjugation rely on the introduction of stable linkers that lack the required versatility to perform sequential functionalizations. However, sequential manipulations are an increasing requirement in chemical biology because they can underpin multiple analyses of the same sample to provide a wider understanding of cell behavior. Here, we present a new method to site-selectively write, remove and re-write chemical functionality to a biomolecule, DNA in this case. Our method combines the precision and robustness of methyltransferase-directed labeling with the reversibility of acyl hydrazones and the efficiency of click chemistry. Underpinning the method is a new S-adenosyl-l-methionine derivative to site-selectively label DNA with a bifunctional chemical handle containing an acyl hydrazone-linker and a terminal azide. Functional tags are conjugated via the azide, and can be removed (i.e. un-tagged) when needed at the acyl hydrazone via exchange with hydroxyl amine. The formed hydrazide-labeled DNA is a versatile intermediate that can be either re-written to reset the original chemical handle, or covalently reacted with a permanent tag. This ability to write, tag, un-tag and permanently tag DNA is exploited to sequentially introduce two fluorescent dyes on DNA. Finally, we demonstrate the potential of the method by developing a protocol to sort labeled DNA using magnetic beads, with subsequent amplification of the sorted DNA sample for further analysis. The presented method opens new avenues for site-selective bioconjugation and should underpin integrative approaches in chemical biology where sequential functionalizations of the same sample are required.

The Relationship Between Using Cannabis, Consuming Isothiocyanate Rich Broccoli, and HDAC Expression in Schizophrenia: A Research Protocol
Authors: Verhoeff Natasha J. , Dhillon Saihajleen K.
Published: February 2020

The legalization of marijuana in Canada raises many concerns regarding its consequences on the central nervous system. From being widely used as a medicinal remedy to now being used recreationally, this proposal aims to focus on an experiment that examines THC and its potentially detrimental effects on the brain, specifically in mice at-risk for schizophrenia. This proposal outlines a mouse model analysis of an analogue of THC that will be constructed using a knockout mice lineage in which the mice have a genetic predisposition to schizophrenia and lack the CB1 receptors responsible for binding THC. The resultant mice will undergo a grooming behaviour test and an elevated zero maze test which will then be compared with other experimental and control groups. This will allow for the direct observation of THC’s effects on the brain, providing insight on the consequences of the legalization of marijuana and its recreational use.

Penelitian ini bertujuan untuk mengetahui profil kolesterol dan trigliserida dalam minyak goreng menggunakan polarisasi cahaya. Serbuk kolesterol murni diperoleh secara komersial kemudian dilarutkan dalam eter dengan tujuan memperoleh kaitan antara perubahan polarisasi dan konsentrasi kolesterol. Nilai tersebut digunakan untuk mengoreksi nilai polarisasi akibat keberadaan trigliserida dalam minyak sebagai komponen utama, dengan asumsi bahwa polarisasi total merupakan kontribusi penjumlahan linier dari polarisasi akibat kolesterol dan polarisasi akibat trigliserida. Hasil peneltian menunjukkan bahwa perubahan polarisasi tidak linier untuk konsentrasi rendah (kurang dari 10 mg/ml). Namun, untuk konsentrasi besar (di atas 10 mg/ml) diperoleh kaitan yang linier antara polarisasi dan konsentrasi kolesterol. Hal ini didukung oleh hubungan linier antara polarisasi dan absorbansi pada puncak serapan gelombang 583 nm. Hasil tersebut memperkuat hasil penelitian sebelumnya yang menunjukkan bahwa kualitas minyak yang baik ditunjukkan dengan polarisasi yang kecil. Dan sebagai tambahan, metode ini tetap mempunyai prospek sebagai instrumen evaluasi tingkat kehalalan minyak akibat cemaran lemak babi.

Pavements are one of the highest assets and represent massive investment. The need to design and provide a sustainable maintenance service is becoming a priority and this comes mutually with the intentions to reduce impacts caused by maintenance treatments to the environment. This paper through a case study presents a Life Cycle Cost and Assessment technique during a 30 year analysis period to measure the cost effectiveness, embodied energy and carbon emissions of selected preservation treatments. These treatments can either be applied separately or in combination during the preventive maintenance of road pavements. This study entails three life cycle phases of material extraction and production, transportation and construction of maintenance activities. Through a literature review, raw materials energy and emission inventory data was averaged followed by the analysis of the equipment involved by using the specific fuel consumption to calculate the energy and emissions spent by the machine and finally the selected treatment energy and emissions was computed. Results show that preservation treatments can have an LCC of 30-40 % and embodied energy and carbon emission of 3-6 times lower than the traditional approach. This study bridges gaps in literature on integrated evaluation of environmental and economic aspects of preservation treatments.

The aim of this study was to evaluate the municipal solid waste (MSW) composition of Peshawar city and its affective utilization for energy purpose in the cement industry. A total 14 days consecutive testing of MSW samples was conducted for winter and summer periods for the purpose of evaluation of the waste composition followed by calculating its heating values. Compliance level of MSW at source was determined which was based upon the questionnaire distribution followed by the financial analysis and feasibility evaluation of the project. The results revealed that the average waste composition of the samples consists of organic waste contents (20.72%), combustible items (37.86%), readily saleable items (20.95%) and other miscellaneous waste items (20.46%). Moreover, the samples were then tested for the evaluation of calorific value and it was found that the heating value of MSW is recorded up to 35513 KJ/Kg whereas; the value for coal is around 38000 KJ/Kg. These findings revealed that the replacement of coal by MSW may be more efficient and might be effectively utilized in the production of cement as the energy production of MSW and coal is nearly same. In addition, the utilization of MSW as a replacement of coal has a great potential of enhancing the service life of the landfills. Besides, NPV analysis of this study revealed that the project is worthwhile to be implemented as it shows high returns regarding financial aspects.

The article presents the results of laboratory studies of pile model foundations in order to determine the effectiveness of the method proposed by the authors for its reconstruction in pile-tile foundation with preliminary pressing and cementation of the soil base. The studies were carried out on small-scale wooden models of foundations in the conditions of a soil paste. The models of foundations were subjected to vertical static loading in a laboratory tray with a diametrical transparent wall. The program of experiments was provided for determination of precipitation of the models: pile foundations without strengthening, with strengthening in the form of reconstruction from the combined foundation and with strengthening in the form of reconstruction into the combined foundation with preliminary stress of the soil base in the span part. Vertical and horizontal movements in the soil mass were also recorded by a contactless method (PIV) in every stage of model loading. On the basis of experimental measurements digital processing of data of sediments and displacements is performed, for drawing plots of sediments, epures and isolines of displacements in the soil base. The main result of the research is confirmation of the high efficiency of the proposed method of strengthening pile foundations due to the maximum use of pre-pressed soil base resources in spans between pile rows. It has been found that compression (pre-stress) significantly reduces soil deformability and allows to include it in operation without additional deformations. The use of pre-compaction reduced the precipitation of the model combined foundation by almost 40%, relative to the combined without compaction. The results of the research open the possibility to develop new methods of strengthening pile foundations from the point of view of effective inclusion in the operation of the soil base in the span part, due to its preliminary tension.
Assessment of SMC Frames under Different Column Removal Scenarios

Published: February 2020

Throughout the past decades, failure of structures threatening the lives of humans had been popular whether through structure failure due to human error such as Hyatt Regency walkway collapse, 1981, terrorist attacks on the American embassy attack in Nairobi, Kenya 1998 and the famous 9/11 attacks in 2001 and many more. As a result of these incidents, The Unified Facilities Criteria (UFC) was developed concerning the progressive collapse issues by analyzing different types of structures under column loss and studying the overall structural behavior. However, the (UFC) didn’t scope on the local behavior of the structural components and its connection under column loss. In this research, the main objective is to study the local behavior of the special moment frame connection (SMC) under column loss. A detailed study is conducted on a 3D model fully designed by adopting the strong-column weak-beam approach following the ACI318-14 regulations. Two frames are selected from the designed structure, interior and exterior frames, to apply the column loss scenario in different locations and different floor levels. The Applied Element Method is adopted in the study. Non-linear time-dependent dynamic analysis is implemented to apply the different column removal scenarios. Twelve case studies are modeled in detail using the Extreme Loading for Structures (ELS) software at which all elements are modeled and analyzed in a 3D model technique. After analyzing the different case studies, structure behavior is observed. Some cases encountered total collapse, other cases encountered partial /local collapse and finally, some survived the column loss scenario. Many parameters are involved and studied in the research.  Failure pattern is observed for collapsed cases, the cause of failure is monitored and studied. Special moment connection behavior is studied concerning the shear connection capacity. The location of the column removal with the type of frame selected played an important role in changing the structural behavior from one case to another. As a result, it is not applicable to assume that due to the special moment connection ductility, the structure will be able to resist the column loss in all cases.

Kabupaten Kendal diharapkan mampu meningkatkan produksi untuk menunjang swasembada pangan. Untuk itu, diperlukan teknologi baru, baik input pertanian (pupuk, benih, pestisida dan lainnya) maupun sistem budidaya tanaman. Tujuan pengabdian masyarakat ini adalah 1) difusi teknologi pertanian UGM kepada petani dan 2) uji coba demplot dengan teknologi pertanian modern. Kegiatan pengabdian dilaksanakan pada April sampai Juli 2016 di Kecamatan Limbangan, Boja, Kangkung, Sukorejo dan Patean. Kelompok sasaran pada pengabdian ini adalah kelompok tani pada lima kecamatan tersebut. Hasil pendampingan program Upaya Khusus Swasembada Pangan menunjukkan kegiatan Rehabilitasi Jaringan Irigasi Tersier ada yang belum terlaksana, kegiatan bantuan benih bersubsidi telah terealisasi sesuai target, kegiatan tanam jajar legowo berjalan dengan baik. Aktvitas penyuluhan memberikan pengetahun baru bagi petani tentang teknologi usahatani (pertanian organik, pembuatan mikoriza dan sistem jajar legowo) dan petani menerapkan teknologi usahatani tersebut pada periode pendampingan. Beberapa masalah yang dihadapi dalam pelaksanaan UPSUS antara lain waktu pendampingan yang terlalu pendek serta pelaksanaan RJIT ada yang terlambat karena kelompok tani belum memperoleh dana dari pemerintah. Dalam rangka pengembangan UPSUS, sebaiknya waktu pendampingan dapat diperpanjang serta dinas juga perlu melakukan pengawasan agar program RJIT dapat dilaksanakan tepat waktu.Kata Kunci : UPSUS, swasembada pangan, penguatan kelembagaan, jajar legowo, demplot
