One-pot synthesis of novel hierarchical bifunctional Ga/HZSM-5 nanosheets for propane aromatization

Hierarchical galloaluminosilicate nanosheets with the MFI structure have been successfully prepared by a one-pot hydrothermal process. Tetrabutylphosphonium hydroxide (TBPOH), a dual structure-directing agent (SDA), was used to simultaneously produce the MFI structure and the self-assemblies of nanolayers. The as-synthesized samples were characterized by means of XRD, TEM, SEM, EDS, ICP, 27Al MAS NMR, H2-TPR, NH3-TPD and N2 physisorption. The galloaluminosilicate nanosheets exhibit outstanding properties, such as an extremely high meso/macroporosity (one to two orders of magnitude higher compared with the conventional zeolite), a uniform Si, Al and Ga distribution, along with the appropriate acidic properties. The galloaluminosilicate nanosheets can greatly enhance the catalytic performances in terms of activity (60 and 20% for propane conversion over the hierarchical Ga/HZSM-5 and the conventional zeolite, respectively), BTX selectivity (almost three times higher compared with the conventional zeolite), and significant reduction of deposited coke (approximately by 70%) for conversion of propane at 823 K under atmospheric pressure without any special pretreatments of catalysts. This first example demonstrates a simple and low-cost approach for the synthesis of hierarchical bifunctional zeolite nanosheets and the challenge for the development of heterogeneous catalysts.
GPU-accelerated molecular dynamics: State-of-art software performance and porting from Nvidia CUDA to AMD HIP

Classical molecular dynamics (MD) calculations represent a significant part of the utilization time of high-performance computing systems. As usual, the efficiency of such calculations is based on an interplay of software and hardware that are nowadays moving to hybrid GPU-based technologies. Several well-developed open-source MD codes focused on GPUs differ both in their data management capabilities and in performance. In this work, we analyze the performance of LAMMPS, GROMACS and OpenMM MD packages with different GPU backends on Nvidia Volta and AMD Vega20 GPUs. We consider the efficiency of solving two identical MD models (generic for material science and biomolecular studies) using different software and hardware combinations. We describe our experience in porting the CUDA backend of LAMMPS to ROCm HIP that shows considerable benefits for AMD GPUs comparatively to the OpenCL backend.
Fixed-point realisation of fast nonlinear Fourier transform algorithm for FPGA implementation of optical data processing

The nonlinear Fourier transform (NFT) based signal processing has attracted considerable attention as a promising tool for fibre nonlinearity mitigation in optical transmission. However, the mathematical complexity of NFT algorithms and the noticeable distinction of the latter from the “conventional” (Fourier-based) methods make it difficult to adapt this approach for practical applications. In our work, we demonstrate a hardware implementation of the fast direct NFT operation: it is used to map the optical signal onto its nonlinear Fourier spectrum, i.e. to demodulate the data. The main component of the algorithm is the matrix-multiplier unit, implemented on field-programmable gate arrays (FPGA) and used in our study for the estimation of required hardware resources. To design the best performing implementation in limited resources, we carry out the processing accuracy analysis to estimate the optimal bit width. The fast NFT algorithm that we analyse, is based on the FFT, which leads to the O(N log22 N) method’s complexity for the signal consisting of N samples. Our analysis revealed the significant demand in DSP blocks on the used board, which is caused by the complex-valued matrix operations and FFTs. Nevertheless, it seems to be possible to utilise further the parallelisation of our NFT-processing implementation for the more efficient NFT hardware realisation.

Oral supplementation with fish cartilage hydrolysate accelerates joint function recovery in rat model of traumatic knee osteoarthritis

Abstract The objective of this study was to evaluate the effects of oral fish cartilage hydrolysate (FCH) on symptoms and joint tissue structure in rat developing osteoarthritis induced surgically. Osteoarthritis was induced in the right knee of mature male Lewis rats (n = 12/group) by surgical transection of the anterior cruciate ligament (ACLT) combined with partial medial meniscectomy (pMMx). Two weeks after surgery, rats were treated orally with either control (sterile H2O) or FCH for four weeks. Pain and function were assessed by dynamic weight‐bearing test (incapacitance test), electronic Von Frey (EVF; hindpaw allodynia threshold), and pressure algometer (knee allodynia threshold). Time and groups differences at each time point were evaluated using a mixed model. The histological features were evaluated eight weeks after surgery using OARSI score. Mann–Whitney test nonparametric test was applied to compare OARSI score. ACTL/pMMx surgery significantly reduced weight‐bearing and increased allodynia and sensitivity thresholds of the operated paw/knee. Globally, FCH improved these parameters faster, but no significant difference between control and FCH groups was observed. Eight weeks after surgery, rats developed moderate OA lesions. Compared with control, FCH did not significantly modify OA lesion severity assessed using the OARSI score. In this mechanically induced OA model, 4 weeks of supplementation with FCH had no significant effect on cartilage lesion, but tends to accelerate pain relief and joint function recovery. This positive trend may have opened the way for further investigation of FCH as potential treatment of joint discomfort associated with OA.
Developments in laser processing of optical fibre radiation sensors

We present simple and robust designs for optical fiber radiation sensors for dosimetry applications, focusing on improved light gathering efficiency. More specifically, we examined the implementation of compound parabolic concentrators (CPC) using scintillator-based optical fibers. The fabrication of the parabolic concentrator is achieved by femtosecond micromachining at the end face of the polymer fiber. Furthermore, we consider the luminous properties of Gadolinium Oxysulfide (GADOX), an inorganic compound usually used in ceramic scintillators, as an alternative and combine it with laser-shaped polymer optical fibers (POF). The simplicity and ease of implementation of the sensor designs offers the prospect of distributed sensors; adding a wavelength shifting element is discussed to make the sensor more adaptable depending on the selected interrogation system.
Conservation implications of living in forest remnants: Inbreeding and genetic structure of the northernmost mantled howler monkeys

The current unprecedented rates of environmental perturbation, particularly in rain forest ecosystems, are jeopardizing the persistence of a variety of tropical species. The development of adequate conservation programs requires incorporating the evolutionary history and population genetic information of species, especially in those threatened by habitat loss and fragmentation. Mexican mantled howler monkeys (Alouatta palliata mexicana) represent the northernmost distribution of primates in America, a Critically Endangered species mainly inhabiting forest remnants. We assessed historical and contemporary patterns of genetic variation in A. p. mexicana populations from five regions across its geographic distribution in Mexico. We employed non‐invasive sampling techniques and evaluated microsatellite loci and mitochondrial cytochrome b sequences from 127 individuals from 15 wild and two semi‐captive populations. Our data demonstrate negative genetic effects on A. p. mexicana as a result of isolation, fragmentation, and small effective population size. Results revealed two mitochondrial lineages and three genetically differentiated nuclear clusters, along with reduced nuclear genetic diversity, limited gene flow, and significant inbreeding, associated with concurrent processes of historical dispersion and contemporary landscape changes. Accordingly, we argue that A. palliata mexicana in Mexico is an independently evolving unit that meets the criteria for being assigned as an Evolutionarily Significant Unit, crucial for the preservation of the howler monkeys’ phylogenetic and functional diversity. The three genetic clusters identified are essential for the maintenance of the adaptive diversity and long‐term survival of this howler subspecies. Our genetic approach and conservation recommendations may be useful for other endangered primates inhabiting fragmented populations.
Removal of some plant toxic heavy metals from soil using Mimosa pigra L. plant and effect of methanolic extract of Acacia nilotica L. on removing efficacy

The principal concern of our study, which is carried out in microcosmic conditions, is focused on removing some plant toxic heavy metals such as Ni, Se, Zn, Pb, Cd, Cr and Cu from soil by using Mimosa pigra plant, as well as the measuring the effect of these harmful elements on some morphological characters of seedlings such as length, number of leaves, fresh weigh, dry weigh and chlorophyll A and B. The investigation also evaluates the effect of Acacia. nilotica methanolic extract (ANME) on heavy metals removing process. Seedlings of M. pigra were subjected to two treatments; first by two different concentrations of heavy metals solutions, the second by adding of ANME. Atomic absorption analysis of seedlings exhibited that M. pigra seedlings had a good ability to remove Ni (20 ppm), Zn (80.01 ppm), Cr (8.82 ppm), Cd (17.57 ppm) and Cu (223.75), especially in case of seedlings treated with high concentrations of heavy metals, while accumulation of Se and Pb was not affected by increasing the concentration of elements. Addition of ANME enhanced the accumulation of Ni (35.1 ppm), Cr (11ppm), and Se (186.24 ppm). Accumulation of heavy metals resulted in reduction in length, number of leaves, fresh weight, dry weight and chlorophyll a and b content of M. pigra seedlings. Statistical data analysis was carried out using One-way analysis of variance (ANOVA).
Investigation of the presence of Legionella pneumophila in water samples from Erzurum and surrounding provinces in Turkey.

INTRODUCTION AND OBJECTIVE Legionnaires' disease, which is a waterborne disease leading to pneumonia that can result in death, is one of the major health issues today. The study aims to carry out a three-year retrospective review of routine Legionella follow-up analyses in various samples taken mostly from hospitals in the province of Erzurum and nearby provinces, and to discover a the frequency of isolation of the agent and serogroups from each kind of media. MATERIAL AND METHODS The study included a total of 2,025 water samples taken from hospitals, hotels, Turkish baths and shopping malls in Erzurum,and 13 nearby cities between 2016 and 2018. Samples were filtered by 0.45 μm-diameter membrane filter paper in the Public Health Laboratory of Erzurum and examined for L. pneumophila using culture method, according to the criteria set out in ISO 11731-2. RESULTS The presence of L. pneumophila was found in 65 of the 2,025 water samples taken in hospitals, and in none of 40 samples taken in hotels, Turkish baths and shopping malls. L. pneumophila serogroup 2-14 was detected in 46 (70.8%) of 65 samples found positive, whereas L. pneumophila serogroup 1 was detected in 18 (27.7%). Furthermore, both the L. pneumophila serogroup 2-14 and L. pneumophila serogroup 1 were detected simultaneously in one example (1.5%). The first three samples indicate that the highest positivity rates were in hot water taps (11.6%), hot water tanks (6.1%) and shower heads (4.8%). CONCLUSIONS The Prevalence rat of L. pneumophila was found to be quite low compared to other studies conducted in the western regions of Turkey. Legionella positivity was found to be higher in the hot water systems of hospitals and related points, compared to the other sample points.
Evaluation of clodinafop-propargyl resistant Avena fatua L. (wild oat) in Sargodha division of Punjab-Pakistan

Avenafatua L. (Wild oat) is one of the world's worst agricultural weeds and is an ever-increasing threat in wheat growing areas of Pakistan. The injudicious application of herbicides for the control of A. fatua has resulted in the evolution of herbicide resistance and made it the second most herbicide resistance weed in the world. Studies were conducted to test the resistance status of A. fatuato clodinafop-propargyl during winter 2018-19 after conducting a field survey for the collection of suspected A. fatuaseeds from various locations of Sargodha division of Punjab, Pakistan. For the resistance confirmation, dose-response assays were conducted under the laboratory and greenhouse conditions. Four doses of clodinafop-propargyl (0, 0.5X, 1X, and 2X) were applied at 3-4 leaf stages of A. fatua. Mortality percentage and dry biomass of different biotypes were recorded at three weeks after herbicide spray. Lethal dose to kill 50% of plants (LD50), and resistance index (RI) were recorded based on mortality percentage. Results revealed that three biotypes (AF-SS-4, AFSS-5 and AF-KSB-1) were resistant to clodinafop-propargyl. The mortality percentage for the resistant biotypes was 53%, 59% and 83%, respectively even at 2X. Resistance index was in the range of 5 to 7. Confirmation of A. fatuaresistance to the selected herbicide was the second case for herbicide resistance in Pakistan. Further research is warranted to evaluate the spreading of herbicide-resistant A. fatua in other areas and to suggest alternate practices to control A. fatua.
Incidental Prostate Cancer in Radical Cystoprostatectomy Specimens is Associated with Worse Overall Survival

BACKGROUND: The impact of incidental prostate cancer (IPC) on oncological outcomes after radical cystoprostatectomy (RCP) specimens from patients with bladder cancer (BC) remains controversial. This relationship has not been well elucidated in Asian countries, where the incidence of prostate cancer has recently shown dramatic increases. OBJECTIVES: This study retrospectively compared pathological features and oncological outcomes between BC patients with and without IPC in the RCP specimens. METHODS: This study included 142 men who underwent RCP for BC. Men who were previously diagnosed with prostate cancer were excluded. Each prostate gland and seminal vesicle was processed as whole mounts and 4-mm close-step sectioning was performed. A single genitourinary pathologist diagnosed IPC. The pathological features and oncological outcomes such as overall survival (OS), bladder cancer-specific survival (BCSS), and progression-free survival (PFS) were compared between patients with IPC (IPC+group, n = 45) and without IPC (IPCgroup, n = 97). P values less than 0.05 considered to indicate statistical significance for patients’ characteristics. Because of multi-primary endpoint, P values less than 0.0167 was considered statistical significance for oncological outcomes. RESULTS: We detected IPC in 45 RCP specimens (31.6%). Patients in the IPCgroup were significantly younger at surgery than those in the IPC+group (P < 0.001). The pathological features of the RCP specimens did not differ significantly. In multivariable analyses, presence of IPC was significantly associated with worse OS (P = 0.005), but not with either BCSS or PFS (P = 0.038 and 0.326, respectively). In Kaplan–Meier analyses, OS tended to be longer in the IPCgroup than that in the IPC+group (NR vs 65 months, P = 0.0017). CONCLUSIONS: Our results suggested significantly better OS in patients without IPC than that in those with IPC.
Indoor positioning system based on magnetic fingerprinting-images

In the latest years, indoor positioning techniques have gained much attention, because of the weakness and absence (GPS) signal, so this paper shows a Low priced mobile mapping system through the use of the advantages of integrating inertial navigation with smartphone sensors (IMU) information concerned to a previous training phase with a magnetic map properly computed to more accurate positioning. Thus, areal online data sets were compiled through the use of Ultra Wide Band (UWB) to furnish an accurate positioning on the whole area of test and compute a trajectory used as a reference. Then, the use of the pedestrian dead reckoning (PDR)-based approach and (IMU) help to supply external information from the Wi-Fi signal that is used to exploit the received signal strength (RSS) path loss, which is possibly used to assess the space between the device and access points (AP)s. Furthermore, these real online data sets have been processed by using Matlab to illustrate the different paths of the area of test. Also, using all (RSS) for every path line, different images were created. At last, the positioning efficiency that is possible to be realized using information from (IMU) and (UWB) accelerated the fingerprinting training phase. So, the graphical analysis is used to summarize the results matches the closest path to the true path by using mutual information.
Low Cost Non-İnvasive Portable Monitor Platform for Cardiac Biopotential and Transthoracic Impedance Measurements

Purpose Simultaneous monitoring of ECG and thoracic electrical bioimpedance (TEB) is important in evaluating cardiovascular performance. TEB is a non-invasive technique based on measuring the impedance value that changes in the chest area depending on the heartbeat. Within the framework of this study, it can be used in home monitoring and biotelemetry applications to measure thoracic electrical bioimpedance (TEB), ECG and ICG. Methods Within the scope of this study, a four-electrode TEB measurement system was designed and built using the Raspberry Pi single board computer and its original monitor, ESP32 and EVAL-ADAS1000SDZ evaluation board. With the designed system, ECG and thoracic impedance measurements at 50 kHz current frequency were taken as real-time over a single channel. Delta_Z and ICG signals were created from thoracic impedance values with the developed software.ResultsWhile the thoracic impedance value varies between 15-45 Ω, the 67 thoracic impedance value measured with the designed system is approximately 1000 times the 68 reference value. The impedance change in the thoracic region was measured with the designed 69 system between 0.1-0.2 Ω values, and the compatibility of these values with reference values was 70 determined. While the reference value of the dZ / dt signal is 0.8 - 3.5 Ω / s, this value is between 2.3 - 71 5.3 Ω / s in the measurements taken with the designed system.Conclusion The prototype is achieved in detecting small changes in the thoracic impedance signal. The prototype is cheap, portable, small-sized and medically safe, so it is suitable for home care services and clinics. In addition, the developed system can be adapted to wearable technology. In order to increase the success of the system, the impedances values added to the thoracic impedance value should be determined and a calibration procedure should be established.
Solid—Liquid—Vapour Equilibria in Water—Salt Systems: A DTA Study at Elevated Temperatures and Pressures

solid of binary systems water—salt have been measured in the high-temperature range starting at the triple point of the pure salt. For that purpose a differential thermal analysis (DTA) has been performed of the phase transition from the two-phase region vapoursolid to the two-phase region liquid —solid. Because of the large volume change related to this phase transition, open DTA cells have been used which were placed in an externally heated pressure vessel. The -ß quartz transition and the melting pressure lines of some salts have been reproduced in the range to 2 kbar in order to test the apparatus.
Model-Based Dynamic Forecasting for Residential Construction Market Demand: A Systemic Approach

According to the previous research, proper demand forecasting could help construction-related firms in effective planning for future market changes. However, existing market demand forecasting models are somewhat limited, and most of them bear some critical shortcomings. This research aims to develop a forecasting model for the Korean residential construction industry using system dynamics. In developing the market forecasting model, this research uses variables that significantly impact future construction market change. Many of the existing models do not include as many variables as this model, and none of them have considered complex interlocking effects among these variables. This model is also the first model using a system-based approach by looking at the target industry as a ‘one complex system’ rather than focusing on individual variables’ impact on future market changes. By employing system dynamics, it is possible to consider qualitative and quantitative aspects and produce long-term market forecasting results. The developed market forecasting model consists of two main modules, the first being a prediction module for the grassroots construction market and the second for operation and maintenance (O&M) and the demolition market. Sixteen input variables are grouped into four categories: social, economy, regulation, and past market size among over 25 identified variables. The model utilizes a mathematical function system using the designed feedback loops in producing future market forecasts. Based on the validation tests with past market data, it turns out that the model is reliable, with the determination coefficient (R2) being over 0.7 on all tested occasions. According to the model’s forecasting results, the Korean construction market’s size is expected to be 231 billion won in 2015 and 286 billion won in 2030. However, the O&M market’s growth rate is expected to be higher than 180%, which is much bigger than those of the grass-root and demolition markets. Thus, this research model is realistic according to the construction paradigm change. This research is considered one of the pioneering studies in construction market forecasting by employing dynamic inter-relationships among various input variables. Therefore, the market forecasting results can be interpreted as more practical and can provide more insights to the construction industry stakeholders. The model is envisioned to provide the public sector with useful guidelines in preparing future public market supply strategies such as construction budget allocations. It would also be helpful for the private sector to develop more proactive and accurate demand strategies for timely decision-making.
