Published: May 2021

Since appendiceal neoplasms have a rare incidence within the spectrum of intestinal neoplasms, they have an important differential diagnosis for patients in the fifth and sixth decade, especially those with a clinical picture suggestive of appendicitis. Mass radiological findings in the periapendicular region, metastatic implants, and ascites may suggest the diagnosis, but it is only confirmed after the surgical approach and biopsy. This case report presents a case of low-grade mucinous appendage tumor with peritoneal pseudomyxoma. It is importance due to its low incidence and, therefore, highlight the main aspects found in the surgery that are fundamental for intraoperative macroscopic diagnosis, choice of treatment technique and treatment.

Produktivitas cabai besar di Provinsi Lampung menurun pada tahun 2018 sebesar 24,7%, dari 88,23 kuintal/ha pada tahun 2017 menurun menjadi 66,41 kuintal/ha pada tahun 2018. Hal tersebut salah satunya disebabkan karena kandungan C-organik tanah yang rendah dan tingginya kerontokan bunga cabai. Limbah baglog jamur merupakan bahan yang potensial digunakan sebagai bahan pembenah tanah karena memiliki sifat porous, sehingga mudah menyerap dan menyimpan air, serta mengalirkan air dalam jumlah yang banyak dan mengandung nutrisi untuk tanaman. Untuk mengurangi serangan kerontokan bunga cabai dapat digunakan sungkup plastik berbentuk melengkung yang dapat menahan jatuhnya air hujan secara langsung pada tanaman dan mengoptimalkan penggunaan pestisida dan pupuk daun. Penelitian ini dilaksanakan dengan tujuan mengkaji pengaruh pemberian limbah baglog dan sungkup plastik terhadap pertumbuhan dan hasil cabai, dan mengkaji pengaruh interaksi antara pemberian limbah baglog dan sungkup plastik terhadap pertumbuhan dan hasil cabai. Penelitian ini telah dilaksanakan di lahan praktik hortikultura Politeknik Negeri Lampung, Bandar Lampung. Waktu penelitian dimulai bulan Juli sampai Oktober 2020. Penelitian ini merupakan percobaan faktorial 3 x 2 dengan menggunakan Rancangan Acak Kelompok (RAK) dengan tiga ulangan. Faktor pertama yang dicoba yaitu dosis limbah baglog yang terdiri dari 0 (kontrol), 20 ton/ha dan 40 ton/ha. Faktor kedua adalah penggunaan sungkup plastik yang terdiri dari tanpa sungkup (kontrol) dan pemberian sungkup plastik. Data yang diperoleh dianalisis dengan menggunakan uji F, jika nyata dilanjutkan dengan Uji BNJ pada taraf 5%. Hasil penelitian menunjukkan pemberian limbah baglog jamur meningkatkan tinggi tanaman, jumlah cabang dan bobot buah cabai per petak. Dosis limbah baglog 40 ton/ha memberikan hasil terbaik pada jumlah cabang dan bobot buah cabai per petak. Penggunaan sungkup plastik tidak berpengaruh terhadap pertumbuhan dan hasil cabai, dan tidak terjadi interaksi antara pemberian limbah baglog jamur dengan penggunaan sungkup plastik terhadap semua variabel pengamatan.

Abstract
The deposition and evolution of fine-grained sediments is a hot topic in fine-grained sedimentary rock studies and is important for accurately evaluating shale gas sweet spots. In this paper, the fine-grained deposition and evolution characteristics of the Wufeng-Longmaxi shales, major targets for Chinese shale gas exploration, were studied by using core observations, thin section analyses, scanning electron microscopy, geochemical analysis, and fossil identification. This work accurately identified six typical lithofacies; among them, the organic matter-rich siliceous shale facies (OMRSSF), the high-organic matter siliceous argillaceous shale facies (HOMSASF), and the medium-high organic matter low calcareous siliceous shale facies (M-HOMLCSASF) are favorable facies for shale gas exploration. The high-resolution isochronous unit in the shelf fine-grained sedimentary system was established, and the differential evolution of lithofacies in the system tract was discussed. The lithofacies deposition and differentiation in the transgressive system tract were controlled by the transgressive scale and tectonics under increasingly shallow water conditions. The lithofacies deposition and differentiation in the regressive system tract were controlled by tectonics and the preexisting lithofacies. The lithofacies in the regressive system tract had more frequent facies transitions and greater differentiation than those in the transgressive system tract, and they exhibited significant spatiotemporal inheritance. Sequential differential sedimentary sequences and symmetric differential sedimentary sequences were distinguished in the continental shelf sedimentary system. The lithofacies depocenters and subsidence centers were consistent in the transgressive system tract, while the tectonically active paleocontinent was important in the regression system tract. This study is of great significance for further high-resolution exploration of marine shale and improvement of the theory of shelf fine-grained sedimentary systems.

Abstract
Performing forest inventory in the campus is one of the breakthroughs towards achieving sustainable campus. Forest inventory aided the universities in creating a holistic baseline or framework in managing, planning and monitoring the forest in the campus in pursuance of a functional urban ecosystem through sustainable practice. The inventory aims to determine the number of trees and the stocking of carbon and biomass. Accurate estimation of the forest’s number of trees and biomass carbon sinks can improve the understanding of carbon cycles and help in developing sustainable forest management. The study area is identified as secondary type forest with 50.1% of the strata is 60–80% canopy cover dominated by small stands. There is a total of 14 sampling plots inventoried and measured using 40 x 40m square plot sampling. 41% of the three species found comprised of rubber trees (Hevea Brasiliensis). The total number of trees estimated is 97,325 trees with the average density of 21 m2/ha and 24,146.54 Mg CO2e aboveground biomass and carbon stocking.

Abstract
Urban resilience to Corona Virus and its globalization has become a major concern for cities these days. The spread of the Corona Virus (Covid-19) pandemic began in early 2020 and gradually spread throughout the world. This pandemic affected all aspects of the individual and social life of the inhabitants of the planet. Our country also has not been safe from the destructive effects of this virus in social, welfare, economic, physical, governance, and management dimensions; and according to official statistics, hundreds of thousands of people in Iran have been infected with this virus and tens of thousands have died so far. Therefore, to measure urban resilience to this pandemic, some criteria and sub-criteria were developed based on the authors’ documentary and field studies, and their significance or weights were determined using analytical-comparative research method using a questionnaire of paired or L-hour comparisons from the viewpoint of experts in urban sciences and urban development using AHP hierarchical analysis in EXPERT CHOICE software. Then, designing a questionnaire with a five-point Likert scale, the satisfaction of Tehran residents with the extracted criteria and sub-criteria was measured and the correlation between the important criteria in each dimension was assessed using correlation tests in SPSS16 software. According to the obtained results of AHP analysis and the scores of each sub-criterion, the weight of all criteria was normal. In the next stage, according to the pairwise correlation tests between the important criteria in each dimension from the viewpoint of urban science experts and Tehran residents, it was concluded that the reliability of the correlation between the criteria is 99%. In all the cases, the P-value or the same significance level was less than 0.05, which indicated the significance of the pairwise relations between the variables.

Abstract
Phosphogypsum (PG) contains a lot of soluble phosphate (PO4 3−-P) and fluorine ion (F−), which seriously has hindered the sustainable development of phosphorous chemical industry. In this study, a new burning raw material (BRM) was used for the stabilize of PO43−-P and F− in PG. The characteristics of PG and BRM, stabilize mechanism of PO43−-P and F−, leaching test and economic evaluation were investigated. The effect of PG and BRM weight ratio, solid to liquid ratio, reaction time and reaction temperature on the concentrations of PO43−-P and F− were studied. The results showed that the concentration of F− in PG leaching solution was 8.65 mg/L and the removal efficiency of PO43−-P was 99.78 %, as well as the pH of PG leaching solution was 8.12, when the weight ratio of PG and BRM was 100:2, and the solid to liquid ratio was 4:1, reacting for 24 h at the temperature of 30 ℃. PO43−-P and F− were mostly solidified as Ca5(PO4)3F, CaPO3(OH), Ca5(PO4)3(OH), Ca2P2O7·2H2O, CaSO4PO3(OH)·4H2O, CaF2, and CaFPO3·2H2O. Leaching test results indicated that the concentrations of PO4 3−-P, F− and heavy metals were less than the integrated wastewater discharge standard (GB8978-1996). Economic evaluation revealed that the cost of PG treatment was $ 0.88/ton. This study provides a new low cost and harmless treatment method for PG.
Investigation of quantum transport and local density of states in a graphene strip connected to a square lattice
Authors: Rostampour Elnaz 
Published: May 2021

Abstract
We theoretically express quantum transport at Dirac points via graphene quantum billiard as a non-magnetic material to connect metallic leads. Our results indicate that the quantum billiard of graphene is similar to a resonant tunnelling device. The centerpiece size and the Fermi energy of the graphene quantum billiard play an important role in the resonant tunnelling. In graphene, change of carrier density can affect plasmon polaritons. At the Dirac point, the conductivity of graphene depends on the geometry, so that the conduction of the evanescent modes is close to the theoretical value of 4e2/πh (where Planck's constant and the electron charge are denoted by h and e, respectively.). This transport property can be used to justify chaotic quantum systems and ballistic transistors. Our theoretical results demonstrate that the local density of state of the graphene sheet for EL = ER = 0 is larger than EL = ER = t (where EL (ER) is onsite energy of the left (right) metallic lead) unlike the current obtained from the calculations.
Designing a One-Dimensional Photonic Crystal via Thue-Morse Sequence Containing Two Types of Double Negative Metamaterial
Authors: Baseri Ali , Keshavarz Alireza 
Published: May 2021

Abstract
This study investigates the propagating of electromagnetic waves through a one-dimensional quasi-photonic crystal with the transfer matrix method. Our proposed structure consists of two types of double negative metamaterials, organized according to the Thue-Morse sequence law. The results show that changing the structure via quasi-periodic arrangements makes the outcome more varied than applying the absolute periodic arrangement. Given that, our desirable results of interest are more conveniently achieved. The structure completely stops-both s and p polarization at the lower frequencies, for all incidence angles. It also partially stops s and p polarization, at higher frequencies. Moreover, the achieved transmittance spectrum contains several omnidirectional band-gaps, which remain invariant with changes in the incidence angle. The oscillation of the transmittance values also becomes more intense at higher orders of the period number. This study could pave the way for optimizing of photonic crystal circuits, splitters, switches, etc.

Abstract
Background

Vertebral artery dissection (VAD), which can possibly lead to stroke, presents various symptoms such as headache, neck pain, transient ischemic attacks, and vertigo. We evaluated the effect of D-dimer to distinguish VAD from benign diseases by retrospective single-center observational study.
Methods

All VAD cases received in the emergency department between January 2013 and June 2020 were reviewed. Comparing those cases to vertigo with benign etiologies, the correlation between VAD and D-dimer was analyzed. Using stepwise multivariate logistic regression, possible symptoms to suspect VAD were also determined from physical findings and some laboratory data, including D-dimer.
Results

Eleven patients were included in the VAD group, and 59 patients were enrolled in the control (benign vertigo [BV]) group. The most common symptom in VAD patients was hemiplegia (N = 7, 63.6%) and cranial neuropathy (N = 7, 63.6%), followed by classic occipital or posterior neck pain (N = 4, 36.4%), gait ataxia (N = 3, 27.3%), and confusion (N = 1, 9.1%). Two patients (18.2%) were free from any symptoms except vertigo. D-dimer was not significantly different between the two groups at the positive cutoff value of 500 ng/mL (p = 1). By stepwise selection, age (odds ratio (OR): 0.92, [0.87–0.98], p < 0.01) and systolic blood pressure (sBP; OR: 1.06 [1.02–1.10], p < 0.01) were selected in the diagnostic model. In combination, age under 60 and sBP over 160 mmHg yielded 63.6% sensitivity, 98.3% specificity, and 37.5 positive likelihood ratio.
Conclusions

In our study, D-dimer was not found to be an effective indicator of VAD. By contrast, disproportionate hypertension (high blood pressure in young patients) can be a key factor to suspect VAD. Future studies with larger sample sizes are warranted.

Abstract
Analytical method have been developed to determine volatile organic compounds (VOCs) in reverse osmosis (RO) membrane using headspace with gas chromatographic mass spectrometry (HS-GC/MS). The operating parameters, including incubation temperature, incubation time and the choice of matrix modifier, were investigated. The existence of matrix effect was checked and the VOC-free RO membrane was selected as the best material for developing matrix-matched calibration curve. At optimum operating conditions, the established method performed good linearity (R > 0.996), repeatability (< 9.5%), VOC recoveries (84.7%—123%) and detection limits (3.44—748 µg/kg). The method was applied to determining thirty-seven common VOCs for RO membrane and toluene and N,N-dimethylformamide were the most abundant VOCs in measured samples, with average contents of 90 087 µg/kg and 249 957 µg/kg respectively. Besides, compounds including acetone, dichloromethane, hexane, chloroform, 1,2-dichloroethane, benzene, chlorobenzene, ethylbenzene, xylene, styrene were also found with content between N.D.—112 419 µg/kg in detection rate between 40%—100%. The analysis of VOC distribution showed the solvents used during the production of the RO membrane were the main source of VOCs in commercial RO membrane. Of these VOCs, dichloromethane, chloroform, 1,2-dichloroethane, and toluene were hardly removed by pre-washing. The relationship between the content of VOCs in RO membrane and their corresponding concentration in filtrated water showed highly positive correlation and the safety limit values for the four compounds were evaluated as 2.6×102–3.8×105 µg/kg, but more accurate and completed guideline values should be formulated to guarantee the RO membrane quality.

Abstract
Technologies that facilitate analyses of circulating biomarkers from blood for cancer detection are powerful tools for improving patient outcomes. Circulating biomarkers derived directly from the primary tumor have been identified including circulating tumor cells (CTCs) and circulating hybrid cells (CHCs), described to harbor phenotypes of both tumor cells and leukocytes. CHCs are present in higher numbers than CTCs which support their translational potential. Methods for isolation of CHCs do not exist and are restricted to low-throughput, time consuming, and biased methodologies. Here, we report development of a label-free dielectrophoretic (DEP) microfluidic platform facilitating enrichment of CHCs in a high-throughput and rapid fashion. Unlike other methods, depletion of healthy peripheral blood mononuclear cells (PBMCs) drives enrichment of CHCs. We analyzed DEP differential response of PBMCs and cancer cells and demonstrated up to 96.5% depletion of PBMCs resulting in 18.6-fold enrichment of cancer cells. In PBMCs from pancreatic adenocarcinoma patients, the platform enriched for neoplastic cells identified by their KRAS mutant status using droplet digital PCR from only 2 mL of whole blood with one hour of processing. Enrichment was achieved in 75% of the clinical samples analyzed, establishing this approach as a promising way to non-invasively analyze tumor cells from patients.
A novel Picture fuzzy linguistic Muirhead Mean aggregation operators and their application to Multiple Attribute Decision Making
Authors: Xian Sidong , Cheng Yue , Liu Zhou 
Published: May 2021

Abstract
The Picture fuzzy linguistic set (PFLS) is an extension of intuitionistic fuzzy set (IFS) and linguistic variables (LVs), which has been applied successfully in the process of decision making. Considering the lack of closeness of extant PFLS operations and the interrelationship among input attributes do not considered. In this paper, for the sake of addressing those limitations, we firstly redefine some novel operational laws for PFLS by introducing linguistic scale functions and the related properties are studied. Then, new score function and accuracy function are also defined to compare PFLSs. Subsequently, in consideration of the superiority of Muirhead Mean (MM) operator in capturing the interaction relationship between the input parameters, we extend the MM operator to the picture fuzzy linguistic context, and then propose picture fuzzy linguistic weighted MM operator and its dual form in a new light. After that, we have adopted these operators to build two novel models to solve multiple attribute decision making (MADM) problems. Finally, a practical example for the selection of the innovative ``Mobike'' sharing bike design is provided to illustrate the practicality and effectiveness of our developed approaches.

Abstract
Background The global impact of Zika virus in Latin America and the Caribbean has drawn renewed attention to circulating mosquito-borne viruses in this region, such as dengue and chikungunya. Our objective was to assess socio-ecological factors associated with Aedes mosquito vector density as a measure of arboviral transmission risk in three cities of potential recent Zika virus introduction: Ibagué, Colombia; Manta, Ecuador; and Posadas, Argentina, in order to inform disease mitigation strategies. Methods We monitored Aedes mosquito populations over 12 months starting in 2018 in a total of 1,086 randomly selected households, using indoor and peridomestic mosquito collection methods. For each sampled household, we collected socio-economic data using structured questionnaires and data on microenvironmental conditions using iButton data loggers. Results A total of 3,230 female Aedes mosquitoes were collected, of which 99.8% were Ae. aegypti and 0.2% were Ae. albopictus. Mean female Aedes spp. mosquito abundance per household was 1.71. We modeled the interaction between neighborhood and household wealth profiles, and found significantly lower Aedes density in highest compared to lowest and middle wealth households, although the effect differed by level of neighborhood wealth. We used mixed-effects Poisson regression analyses to identify predictors of Aedes density, using month, neighborhood, and country as random-effect variables. Across study sites, the number of household occupants (Incidence rate ratio, IRR = 1.08), presence of entry points for mosquitoes into the household (IRR = 1.51), and presence of decorative vegetation (IRR = 1.52) were associated with higher Aedes density; while being in the highest wealth tertile of household wealth (IRR = 0.78), knowledge of how arboviruses are transmitted (IRR = 0.94) and regular emptying of water containers by occupants (IRR = 0.79) were associated with lower Aedes density. Conclusions Our study addresses the complexities of arbovirus vectors of global significance at the interface between society and the environment. Our results point to several determinants of Aedes mosquito vector density in countries with co-circulation of multiple Aedes-borne viruses, and could help us identify targets of practical intervention for disease prevention and control.
