Location determination of hierarchical service facilities using a multi-layered greedy heuristic approach

Many urban areas in developing countries are experiencing dramatic growth in both population and economy, which highlights the need for optimizing service affordance by the government. Driven by this demand, this article proposes a new concept, namely the hierarchical service facility (HSF), for managing services with multiple levels of service range. The challenge is to strategically position HSFs to cover all residents of a subdistrict at every service range level with a minimum cost. To this end, this location determination issue was formulated into a hierarchical discrete unit disk cover (H-DUDC) problem. An algorithmic solution using a multi-layered greedy heuristic was developed to solve the H-DUDC problem, and its effectiveness was validated through a practical case study. The experimental results indicate that the HSF concept is an effective tool for optimizing service resource distribution and balancing the use of public services in different sub-zones of a residential area.
The Moderator Role of Culture in the Relationship between Destination Brand Equity and Travel Intention

Brand equity and destination branding subjects are among the most important issues in the field of destination marketing that have concerned the business managers and destination management organizations operating in the tourism sector. Particularly in recent periods, as a result of the growing competition, there has been a significant increase in the studies on the branding of a destination. The main objective of this research is to determine the effect of destination brand value on travel intention and examine the moderator role of cross-cultural differences in this effect. Another primary objective of the research is to ascertain the effect of destination brand equity on travel intention. Besides, the moderator role of intercultural difference on the mentioned effect has been examined. The research was carried out with the participation of 395 tourists from different countries in Side, considered one of Turkey's most important tourist destinations. The research data were collected by convenience sampling method, and the created model was tested with structural equation modeling. Besides, Process Macro was used in order to determine the moderator effect. When the research results were examined, it was concluded that the brand equity dimensions of destination brand awareness and destination loyalty had a significant effect on travel intention. In addition to these, tourists from Europe and Asia play a moderator role in this effect. The absence of a study among the studies that measure the relationship between brand equity and travel intention that determines the moderator role of culture reveals the originality of the study and its contribution to the literature. In the light of the results taken from the research, a number of suggestions have been presented to sector representatives, academicians studying in the literature, and destination management organizations, as well.
Promoting Domain-specific Forum Participation via Off-topic Forum Participation in Electronic Networks of Practice

In this paper, we investigate how members’ participation in off-topic social forums in electronic networks of practice (eNoPs) influences their propensity to participate in their domain-specific forums. Currently, the literature offers two theoretical arguments that would predict opposing outcomes concerning the impact that off-topic forum participation has on domain-specific forum participation. We argue that investigating the network structure of the off-topic forum has the theoretical flexibility to reconcile these opposing theoretical arguments. Specifically, we hypothesize that an off-topic forum’s overall network structure (network cohesion as determined by the global clustering coefficient) moderates the impact of off-topic forum participation on domain-specific forum participation. We theorize that, given equal conditions, off-topic forum participation creates social bonds that positively affect domain-specific forum participation when the off-topic forums have a highly cohesive network structure. Contrarily, however, we posit that off-topic forum participation becomes a noisy distraction when the off-topic forum has a less-cohesive network structure. We provide empirical support for these hypotheses via a 10-year longitudinal study of software developers’ participation in an electronic network of practice (eNoP). Our paper highlights new theoretical insights on the network effects in an eNoP whereby network structures in one section (off-topic forums) have ramifications for behaviors in a different section (domain-specific forums).
Differential tolerance of Trichoderma harzianum and Rhizoctonia solani towards silver nanoparticles: potential for agricultural applications?

In the previous study, we examined the effect of silver nanoparticles (AgNPs) on beneficial soil fungus including Trichoderma harzianum (T22), and pathogenic soil-borne fungus, Rhizoctonia solani (AG3-PT). The result exhibited that T. harzianum (T22) is tolerance towards AgNPs. On the other hand, the pathogenic fungi, R.solani (AG3-PT), is more sensitive to AgNPs. T. harzianum is well known as biocontrol agent to suppress R. solani. Therefore, in this study we investigated the combination of T. harzianum (T22) and AgNPs at low concentration to control two strains of R. solani (AG3-PT and AG2-1). The effect of AgNPs at two different levels (20 mg L-1 and 50 mg L-1) was examined over the growth of the two strains of R. solani and T. harzianum (T22) using dual culture technique. The results shows that this combination have a potential to reduce colony growth of R. solani (AG2-1) at higher AgNPs concentration. However, it was not the case for R. solani (AG3-PT). It can be concluded that AgNPs toxicity depend on several factors including species strain and the size of AgNPs particle.
Effect of somatic cell count of cow’s milk on the lipolysis and fatty acid profile of farmer cheese

The objective of the present work was to investigate the effect of somatic cell count (SCC) of raw cow’s milk on the lipolysis and oxidative processes in farmer cheese. The farmer cheese samples were produced from three different batches of raw cow’s milk of low (about 100,000 cells/mL, batch L), medium (between 500,000 and 600,000 cells/mL, batch M), and high (above 1,500,000 cells/mL, batch H) SCC. The farmer cheese samples were aged and cold-stored at 4 ± 1°C for three and ten months, respectively. Lipolysis in the farmer cheese samples was evaluated by monitoring the changes in cheese fatty acid values and peroxide values, as well as the changes in the fatty acid profile. Results indicated intensive lipolysis during aging and cold storage of batch H; increased concentrations of short-chain fatty acids as well as a higher percentage of saturated fatty acids were observed. It can thus be concluded that the accelerated lipolysis in farmer cheese samples made from raw cow’s milk with high SCC could cause some quality defects, and reduce cheeses’ shelf life.
A NUMERICAL INVESTIGATION OF FLUID FLOW AND HEAT TRANSFER IN A THREE-DIMENSIONAL PLAIN FIN-AND-TUBE HEAT EXCHANGER

ABSTRACT A numerical investigation of the airside performance of a plain fin-and-tube heat exchanger having 4 row configurations has been presented in this study. Fluid flow is steady, incompressible and three dimensional. Laminar (400<Re H <1200) and transitional (1300<Re H <2000) flow conditions are considered for both in-line and staggered tube arrangements. For transitional flow calculations, the k-ω turbulence model is used. Uniform flow with constant velocity and temperature are considered at inlet and no-slip boundary condition and constant wall temperature is assumed at fin and tube surfaces. In this study the geometrical parameters such as fin pitches, longitudinal pitches and transverse pitches of tube spacing are studied. The results are compared with previous experimental data of Wang et al. [1]. Results are presented in the form of friction factor (f) and Colburn factor (j). For both laminar and transitional flow conditions heat transfer and friction factor decrease with the increase of longitudinal and transverse pitches of tube spacing whereas they increase with fin pitches for both in-line and staggered configurations. Efficiency index increases with the increase of longitudinal and transverse pitches of tube spacing but decreases with increase of fin pitches. For a particular Reynolds number the efficiency index is higher in in-line arrangement than the staggered case.
Long-Term Prognostic Factors in Patients With Antineutrophil Cytoplasmic Antibody-Associated Vasculitis: A 15-Year Multicenter Retrospective Study

Background Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a multisystem autoimmune disease with small-vessel involvement. In AAV, microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA) are major clinicopathologic variants. In addition, myeloperoxidase (MPO) and proteinase 3 (PR3) are major target antigens. The objective of the study was to explore the predictive factors for long-term survival in AAV patients. Materials and Methods A multicenter retrospective study was carried out on 407 patients between 2005 and 2020. Clinical parameters were obtained from laboratory tests including the ANCA types, antinuclear antibody (ANA), extractable nuclear antigen (ENA), anti-streptolysin O (ASO), glomerular filtration rate (GFR), and the laboratory examinations for the blood routine, liver function, renal function, and immunity, etc. The data for clinical parameters were collected from electronic medical records (EMRs), and the data for patient survival were acquired through regular follow-up. The association of clinical parameters with overall survival (OS) along with 3-year and 5-year survival rates was analyzed, and the nomogram as a predictive model was established according to the analysis results. Results In the present study, 336 (82.6%) patients and 46 (11.3%) patients were diagnosed with MPA and GPA, respectively. The mean and median OS for all the patients were 2,285 and 2,290 days, respectively. The 1-year, 3-year, 5-year, and 10-year cumulative survival rates for all the patients were 84.2%, 76.3%, 57.2%, and 32.4%, respectively. Univariate and multivariate survival analyses indicated that the independent prognostic factors included age, pathological categories (MPA, GPA, and other types), serum ANCA types (negative or positive for MPO and/or PR3), ANA, ASO, GFR, lymphocyte, neutrophil-to-lymphocyte ratio (NLR), and C-reactive protein (CRP), and these clinical parameters except for ASO were used to construct a nomogram. The nomogram for 3-year and 5-year survival rates had a C-index of 0.721 (95% CI 0.676–0.766). The calibration curves showed that the predicted values of the nomogram for 3-year and 5-year survival rates were generally consistent with practical observed values, and decision curve analysis (DCA) further demonstrated the practicability and accuracy of the predictive model. Conclusion Laboratory tests at diagnosis have great significance in the prediction of long-term survival in AAV patients.
MSFgNet: A Novel Compact End-to-End Deep Network for Moving Object Detection

Moving object detection (MOD) in videos is a challenging task. Estimation of accurate background is the key to extracting the foreground from video frames. In this paper, we have proposed a novel compact end-to-end convolutional neural network architecture, motion saliency foreground network (MSFgNet), to estimate the background and to extract the foreground from video frames. Initially, the long streaming video is divided into a number of small video streams (SVS). The proposed network takes the SVS as an input and estimates the background frame for each SVS. Second, the saliency map is extracted using the current video frame and estimated background. Furthermore, a compact encoder–decoder network is proposed to extract the foreground from the estimated saliency maps. The performance of the proposed MSFgNet is tested on three benchmark datasets (CDnet-2014, LASIESTA, and PTIS) for MOD. The computational complexity (handling of number of parameters and execution time) and the performance of the proposed MSFgNet are compared with the existing state-of-the-art methods for MOD in terms of precision, recall, and F-measure. Performance analysis shows that the proposed network is very compact and outperforms the existing state-of-the-art methods for MOD in videos.
The Validity of The FRAIL Scale in Frailty Screening Among Vietnamese Older People

Background/Purpose: A simple and effective frailty screening tool is required for use among older people in outpatient clinics. We aimed to evaluate the validity of the Vietnamese version of the FRAIL-scale (FRAIL-VI) for frailty screening in Vietnam. Methods: This was a cross-sectional study conducted at the Geriatric clinic of Gia Dinh People’s Hospital in Ho Chi Minh City. Frailty was evaluated using the FRAIL scale and Fried’s criteria. Stata version 14 was used for data analysis. We used receiver operating characteristic (ROC) analyses, the area under the curve (AUC), sensitivity, specificity, and positive and negative predictive values to assess diagnostic accuracy of the FRAIL scale, when compared with Fried’s criteria. Box and Whisker plots were obtained to present the distribution of the FRAIL scores according to Fried’s criteria, and Pearson’s correlation coefficient was calculated to examine the correlation between the two tools. Results: The study included 396 participants (mean age of 72.6±7.6, 62.1% female). The optimal cut-off value for the FRAIL scale was ≥2, with 94.7% sensitivity, 85.2% specificity, and a Youden index of 0.799. In ROC analysis, the FRAIL-VI AUC was 0.964 (95% confidence interval: 0.95 – 0.98), when compared with Fried’s criteria. The FRAIL-VI scale had a high positive correlation with Fried’s criteria, with a Pearson’s correlation coefficient of 0.81 ( p <0.001). Conclusion: The FRAIL scale is a valuable frailty screening tool when compared with Fried’s criteria. A cut-off value of ≥2 may be useful in primary care settings.
Preharvest Methyl Jasmonate Treatment Increased Glucosinolate Biosynthesis, Sulforaphane Accumulation, and Antioxidant Activity of Broccoli

Broccoli is becoming increasingly popular among consumers owing to its nutritional value and rich bioactive compounds, such glucosinolates (GSLs) and hydrolysis products, which are secondary metabolites for plant defense, cancer prevention, and higher antioxidant activity for humans. In this study, 40 μmol/L methyl jasmonate (MeJA) was sprayed onto broccoli from budding until harvest. The harvested broccoli florets, stem, and leaves were used to measure the contents of GSLs, sulforaphane, total phenolics, and flavonoids, as well as myrosinase activity, antioxidant activity, and gene expression involved in GSL biosynthesis. The overall results revealed that GSL biosynthesis and sulforaphane accumulation were most likely induced by exogenous MeJA treatment by upregulating the expression of CYP83A1, SUR1, UGT74B1, and SOT18 genes. Exogenous MeJA treatment more remarkably contributed to the increased GSL biosynthesis in broccoli cultivars with low-level GSL content (Yanxiu) than that with high-level GSLs (Xianglv No.3). Moreover, MeJA treatment had a more remarkable increasing effect in broccoli florets than stem and leaves. Interestingly, total flavonoid content substantially increased in broccoli florets after MeJA treatment, but total phenolics did not. Similarly, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging capacity, trolox-equivalent antioxidant capacity (ABTS), and ferric-reducing antioxidant power (FRAP) were higher in broccoli floret after MeJA treatment. In conclusion, MeJA mediated bioactive compound metabolism, had positive effects on GSL biosynthesis, sulforaphane, and flavonoids accumulation, and showed positive correlation on inducing higher antioxidant activities in broccoli floret. Hence, preharvest supplementation with 40 μM MeJA could be a good way to improve the nutritional value of broccoli florets.
Gluten-free tarhana fortified with different ratios of edible mushroom Lactarius deliciosus

The present work aimed to develop nutritious and delicious tarhana soup for people who are especially sensitive to gluten. An edible mushroom, Lactarius deliciosus, was used in the gluten-free soup formulation instead of rice flour with different fortification ratios (0, 25, 50, 75, and 100%). Ash, protein, fat, mineral, acidity, water and oil absorptions, total phenolics, and antioxidant activities of gluten-free tarhana samples increased with the fortification of L. deliciosus in a dose-dependent manner, though the samples lost their lightness (L*), hue angle (H°), and chroma (C*) values. Total carbohydrate was calculated by subtracting the sum of crude ash, protein, and fat contents, and determined in the range of 64.31 - 78.51%. Potassium was the most abundant mineral found in samples, followed by calcium, and magnesium. Total polyphenols increased to 14,847.28 from 1,526.46 mg/kg gallic acid equivalent (GAE) for 100% fortification of L. deliciosus powder on dry weight basis (DWB). Antioxidant activity by ferric reducing antioxidant power (FRAP) assay (3.01 - 10.14 mmol Trolox equivalent, TE/kg DWB) was comparably higher than that with the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay (1.09 - 8.81 mmol TE/kg DWB). Gluten-free tarhana sample fortified with 25% L. deliciosus powder (DWB) had the highest sensory scores with respect to colour, taste, mouthfeel, and overall acceptability.
CORRELATION BETWEEN ELEMENTS OF A MASSIVE MIMO ANTENNA IN A SUB-6 GHZ MOBILE TERMINAL

|This work studies the correlation between 14-elements of a sub-6 GHz MIMO antenna for mobile terminal, operating in the 3.10 to 3.85 GHz frequency band. Envelope correlation coeﬃcient (ECC) was used to assess the relationship between MIMO antenna elements. A total of 91 ECC values were considered at every frequency point for the 14-element antenna, which was performed under two propagation scenarios: (i) a uniform environment, and (ii) a Gaussian environment. For the latter, three angular spreads (AS) of 20 ◦ , 30 ◦ , and 40 ◦ and incident angle of every 10 ◦ in both elevation and azimuth coordinates are considered. The resulting ECC in the uniform environment is below 0.15 over the entire operating frequency band, indicating that the 14 elements are minimally correlated. However, in a Gaussian environment, the ECC is evaluated at 3.25 GHz. For the AS values of 20 ◦ , 30 ◦ , and 40 ◦ . The average number of ECC values below the 0.3 threshold is 48, 67, and 81 out of 91 total ECC values, respectively. Finally, a relation is derived between the number of ECC values below 0.3 and the lowly-correlated number of antenna elements. It is seen that at a wider angular spread of 40 ◦ , the number of equivalent lowly-correlated elements is 12 with 87% from all considered incident wave directions.
ANTIBACTERIAL PEPTIDE FROM SOLID PHASE EXTRACTION (SPE) FRACTIONATION ON TRYPSIN HYDROLYSIS OF JATROPHA (Ricinus communis) SEED PROTEIN ACID EXTRACT

The antimicrobial peptide is a new potential antibiotic type that can be isolated not only from free peptides but also peptides from hydrolyzed protein with proteolytic enzymes. The protein of jatropha seed is toxic due to RIP, ribosomeinactivating protein, and a potential source of AMP. Trifluoroacetic acid was used to isolate jatropha seed protein. The protein was hydrolyzed using trypsin and the hydrolysate separated with a cation exchange solid phase extraction (SPE) column. Each fraction was tested for antimicrobial activity and resulted in the pH 3 and pH 4 fractions being able to inhibit bacterial growth against Staphylococcus aureus (Gram-positive bacteria) and Escherichia coli (Gramnegative bacteria). The pH 3 fraction has IC50 value 17.95 µg/mL to E. coli and 17.03 µg/mL to S. aureus, while the pH fraction has IC50 value 37.30 µg/mL and 95.31 µg/mL respectively. There are three peptides with amino acid sequences of GAGLVPKR, MGACCSKEPSFAEGR and VALASLLSQPLPQISDK identified from those fractions. These peptides potentially inhibit bacterial growth through membrane destabilization mechanism, due to their amphipathic and ionic properties.

PRODUCTION OF HIGH QUALITY DEHYDRATED FOOD PRODUCTS BY SIMPLE TECHNIQUE FOR SMALL PROJECTS

he objective of this study was to dry onion and potato with a simple technique for small projects. Both of onion and potato slices submerged in yeast ( Saccharomyces cerevisiae ) suspension for 2, 4 and 6 hours as a pretreatment and then, the samples were preheated in air ventilation oven at 120ºC for 15 mins. All samples were dried under sunlight until reached to final moisture content 9-10%. The aims of the thermal treatment (at 120ºC for 15 mins.) were sterilized, inhibition the yeast and enzymatic browning, beside, decrease the moisture content, sundried time and partial gelatinization of potato starch. The physiochemical characteristics, microbiological count and Sensory evaluation for both onions and potatoes were estimated. The results showed that, the increasing of fermentation periods led to increase the growth rate of yeast while, the pH value, total soluble solids and color index decreased. Also, the results explained that, decreased of phenol compounds, flavonoids and antioxidant activity by increasing the time of fermentation process and pungency (as pyruvic acid) for dried onion. Meanwhile, no significant difference observed in rehydration characteristics of both treated, dried onion and potato samples by increasing the time of the fermentation process. Finally the results showed that, the Samples submerged in yeast suspension for four hours, preheated at 120 ºC for 15 min. and drying under direct sunlight had high nutritional value and good quality. were higher than those of dried treatments. The results showed that there were significant differences between T1 and all treatments for dried onion and potato in total carbohydrates. Oven hot air-dried samples relatively lost more carbohydrates than all the other samples. This decreased in carbohydrate content probably occurred as a result of Millard reaction. The differences in the carbohydrate contents may be attributed to the effect of the drying temperature.
