Robust circuitry-based scores of structural importance of human brain areas.

We consider the 1015-vertex human consensus connectome computed from the diffusion MRI data of 1064 subjects. We define seven different orders on these 1015 graph vertices, where the orders depend on parameters derived from the brain circuitry, that is, from the properties of the edges (or connections) incident to the vertices ordered. We order the vertices according to their degree, the sum, the maximum, and the average of the fiber counts on the incident edges, and the sum, the maximum and the average length of the fibers in the incident edges. We analyze the similarities of these seven orders by the Spearman correlation coefficient and by their inversion numbers and have found that all of these seven orders have great similarities. In other words, if we interpret the orders as scoring of the importance of the vertices in the consensus connectome, then the scores of the vertices will be similar in all seven orderings. That is, important vertices of the human connectome typically have many neighbors connected with long and thick axonal fibers (where thickness is measured by fiber numbers), and their incident edges have high maximum and average values of length and fiber-number parameters, too. Therefore, these parameters may yield robust ways of deciding which vertices are more important in the anatomy of our brain circuitry than the others.

Periodic Variations of Solar Corona Index during 1939–2020

Periodic behaviors of solar magnetic indicators might provide a clue for the understanding of solar dynamic processes. Combining with a Lomb–Scargle periodogram, the concentration of frequency and time via a multitapered synchrosqueezed transform is applied to investigate the periodic variations of modified coronal index for the time interval from 1 January 1939 to 31 August 2020. The main results are as follows: (1) During solar cycles 19 to 23, the Schwabe cycle of the modified coronal index is operating with its length variating between 10.5 and 11-yr, and the average value of length is 10.67-yr with standard deviation of 0.14-yr. (2) The Rieger-type periods are mainly distributed in a range from 120 to 200 days. In addition, the periods vary somewhat intermittently during cycles 18 to 24, which are operating with the highest power in cycles 21 and 22 while the power is much lower in cycles 23 and 24. (3) For rotation periods, the temporal variation exhibits a highly intermittent pattern as an asymmetrical distribution with its 25th, 50th, and 75th quantile of 26, 27.8, and 31-day, respectively. (4) Other mid-range periods are also detected with an average period length of 8.07, 5.44, 3.42, 2.3, and 1.01-yr.

Symmetrical comparison of crown size, morphology and gingival shape in maxillary incisors

Background: Maxillary anterior tooth proportion has special value in dental aesthetics. Restorative dentistry often involves correcting tooth size discrepancies. Therefore, dental biometrics should play an important role in the planning of an aesthetic restoration. Objectives: To assess and compare clinical crown dimensions and classify crown shape and gingival shape of the maxillary incisors in order to collect anatomical data on the anterior teeth of young population visiting the tertiary centre. Methods: This descriptive cross-sectional study conducted in department of Prosthodontics in November 2021 after getting ethical approval among dental students and patients attending the hospital, with permanent healthy dentitions. Impression of maxillary and mandibular arches were made with alginate and poured in dental stone. Measurement of maxillary central incisors was done for length and thickness with the digital vernier calliper. Convenience sampling was done. Data were recorded and analysis done with SPSS v.20. Results: The mean value of crown length, crown thickness, mesiodistal width of left central incisor was greater compared to the right side (Left vs Right: 9.01 ± 1.14 mm vs 9 ± 1.14 mm , 7.04 ± 0.67 mm vs 6.96 ± 0.61 mm, 8.25 ± 0.59 mm vs 8.20 ± 0.51 mm). Conclusion: Crown length and crown width of maxillary left central incisor were greater compared to maxillary right central incisor. Shape of maxillary incisors determines the shape of the gingiva. The average values of length and widths of the central incisors derived from this study can be a valuable template for prosthodontic and aesthetic planning.

Determination of the swim bladder parasite Anguillicola crassus (Nematoda, Dracunculoidea) in the European Eel, Anguilla anguilla (Linnaeus, 1758) from the locality Çamalti Tuzla of Izmir Bay, Eastern Aegean Sea

We, here, aimed to determine the presence of Anguillicola crassus, a swim bladder parasite, in 89 (male: 45, female: 44) dead European eel specimens obtained seasonally between 2020-2021 from a regional fisherman, who has fished with fyke net in the locality Tuzla of Izmir Bay, Eastern Aegean Sea. Out of 21 male European eels caught in winter, only one specimen (TL: 48.5 cm and TW: 247.12 g) had 23 swim bladder parasites (adult nematodes: 15, larvae: 8) and similarly, only one parasite was found in one specimen (TL: 37.5 cm and TW: 88.47 g) of 8 eels caught in spring. No parasite was found in the female eels. At the examinations, it was determined that all adult Anguillicola crassus specimens were females and the minimum-maximum and average length values in adult and larval parasites were, respectively, 1.5-2.5 cm (1.99 ± 0.31) and 0.7-1.3 cm (1.025 ± 2.40). Consequently, the species A. crassus, a swim bladder parasite, was found in European eels from the locality Çamalti Tuzla in two seasons (winter and spring) and this parasitic nematode were only in male eels. This study is a first and remarkable one having evidential value, which shows the presence of the species A. crassus among the eel population in the locality Çamalti Tuzla of Izmir Bay. Besides, it is a population that should be monitored due to the status of Anguilla anguilla on the IUCN red list.

Application of biochemical and morphophysiological parameters of round goby Neogobius melanostomus (Pallas, 1814) for assessment of marine ecological state.

The ecological state assessment of the two areas in the Sea of Azov (Temryuk and Yasensky Bays) was carried out using morphophysiological (hepatosomatic and gonadosomatic indices) and biochemical parameters (activity of antioxidant enzymes (superoxide dismutase, catalase), aminotransferases, cholinesterase, level of oxidized proteins, and lipid peroxidation), as well as the toxicological parameters in the liver of round goby Neogobius melanostomus. The results of the biochemical analysis allowed to establish a shift of the prooxidant-antioxidant reactions towards the processes of protein oxidation, also an increase of aminotransferase activities in the fish liver from Temryuk Bay compared to similar indicators in fish from Yasensky Bay. At the same time, the average values of length and weight as well as the gonadosomatic index were found significantly lower, while the hepatosomatic index significantly higher in fish from Temryuk Bay as compared to similar indices of fish from Yasensky Bay. Analysis of the biochemical and morphophysiological parameters of round goby from the two locations demonstrates less favorable ecological state of the Temryuk Bay that fully agrees with the results of the elementary analysis in the fish liver. Studied parameters can be used in the ecological monitoring of the natural surroundings of this species and the areas beyond.

Abstract The paper presents the results of research on the reproductive biology of Syngnathus abaster – a species distributed in Çandarli Bay. For this purpose, seine nets were collected from a depth of 0.5–2 m in 15 minute periods between April 2013 and March 2014, and a total of 185 individuals were sampled. It has been determined that 94 individuals (50.81%) were females, 79 were males (42.70%) and 12 were immature (6.49%). The sex ratio was 1:0.84. The average length values in female, male and immature individuals were 111.5 ± 7.35, 109.9 ± 11.08 and 79.8 ± 5.30 mm, respectively. The maximum mean surface water temperature is in spring and summer seasons. When Gonadosomatic Index (GSI%) values were examined, the spawning period of the species was indicated as spring and summer. Three groups of species were identified as maturing (diameter: 0.61–1.20 mm), mature (diameter: 1.21–1.70 mm) and hydrated oocytes (diameter: 1.71–2.10 mm) in ovaries of female individuals. The number of eggs in the brood pouch of pregnant male fishes was on average 48 (mean ± SD = 48 ± 14.09 eggs, range: 23–78 eggs). The hydrated oocyte/total length relationship was: y = 0.8651x – 84.332 (n = 14, r2 = 0.64) and the number of eggs/total length relationship in the brood pouch of pregnant males was: y = 1.0168x – 67.715 (n = 33, r2=0.58).

Portuguese

The objective was to evaluate morphometric characteristics of the ovaries and incidence of corpus luteum and ovarian follicles in empty zebu crossbreed’s cows obtained from slaughterhouses, in the region of Uberlândia, Minas Gerais. The average values of length, width and thickness of the rights ovaries (OD) were, respectively, 3.5 cm, 2.3 cm and 1.70 cm. For the left ovary (OE) the measures were: 3.4 cm, 2.0 cm and 1.60 cm. The mean diameter of the follicles found in the OD was 1.1 cm and OE 0.8 cm. The comparison between findings on the right and left ovaries was performed using the T test, with significance level of 5% (p <0.05) and the width was higher in right ovaries (p-value: 0.02). Of all the corpus luteum, 61% were present in the OD and 39% present in the OE. To classify the type of this corpus luteum, it was found that 68% of corpus luteum were protruding and 32% were included. The size of the ovaries and the high incidence of included corpus luteum should be considered as major factors when performing gynecological examination by rectal palpation.

Synthesis and Characterization of Nanostructured Nickel Diselenide NiSe2 from the Decomposition of Nickel Acetate, (CH3CO2)2Ni

Solution processed NiSe2 nanorods were synthesized by a modified colloidal synthesis technique, by chemical reaction of TOPSe and nickel acetate at 150°C. The rods exist as an oleic acid ligand stabilized solution, with oleic acid acting as a capping group. Structural characterization by X‐ray diffraction and transmission electron microscopy indicates that the particles are rod‐like shaped crystals with a high and relatively constant aspect ratio (30 : 1). TEM shows that the width and the length of the nanorods are in the range 10–20 nm and 300–350 nm, respectively. XRD indicates that the nanorods are pure and well crystallized. The size of nanorods based on the Debye‐Scherrer effect, was 150 nm, the average value of length and width. They display thermal stability over prolonged heating times (&lt;100 hours) at 150°C, for which the average particle size is roughly constant. After about 100 hours of heating time there is an onset and growth of micron sized cubes and concurrent decomposition of NiSe2 to Ni and NiSe at 150°C.

Some Physical Properties and Proximate Composition of Ipoli Fruits

In this study, some physical properties desirable to the design and development of handling and processing equipment, as well as the proximate composition of Ipoli fruit was evaluated. Results show that average values of length, width, thickness andgeometric mean diameter were 20.20 mm, 13.91 mm, 6.92 mm and 12.45 mm respectively at a moisture level of 85.2% (wet basis). Sphericity, aspect ratio, surface area and volume were found to be 62%, 70%, 438.27 mm2 and 1227.84 mm3 respectively, while coefficient of static friction on mild steel, rubber and plywood surfaces were found to be 1.294, 1.140 and 1.016 respectively. The nutritional facts also reveal that Ipoli fruit contains 6.2% Carbohydrate, 0.8% protein, 1.7% ash content, 0.18% Vitamin A and 0.42% Vitamin C. It is therefore recommended that Ipoli fruit consumption and cultivation be encouraged and the mechanization of its unit operations be considered.

하수구 막힘 방지를 위한 모발 절단 분쇄 장치 개발 및 성능평가

Abstract : The recalcitrant hairs which are accumulated in the U-trap equipped to prevent the stench from the drainage produce the phenomenon of blocking the flow of water through the home drainage pathway. The chemical dissolution solutions commer-cially manufactured are excessively poured into U-trap to solve this blocking problem. In this study, the specially designed instrument was developed for the experiments to cut and crush the hairs of which main component are the recalcitrant keratin proteins. The performance of the instrument for cutting and crushing hairs was investigated using experimental methods. The cutting and wei-ghing method was used in order to obtain the average length of a large amount of hairs cut by instrument. This method is relati-vely simple to measure the weight of cutting hairs to obtain the average length of the fibers, the values of average length showed not greater tolerances. Also the average cutting number was defined to evaluate the performance of the cutting and crushing instru-ments designed for this study. We were able to apply these evaluation methods to provide the criteria to obtain the optimal structure of instrument and proper operation time in the given experimental conditions. These experimental methods and results will provide the good example to design and to analyze the various device that can be used for cutting the fibers. The cutting and crushing instrument developed in this study showed the effective abilities to cutting the hairs. The general using the cuttting and crushing instrument at every home would be helpful to prevent water environmental pollution.

A Methodology for the Analysis of Dimensional Features of Traditional Rural Buildings to Implement the FarmBuiLD Model

The FarmBuiLD (Farm Building Landscape Design) research model aims at defining farm building design criteria that can combine improved architectural and landscape quality with functional efficiency. FarmBuiLD moves from the consideration that historic rural buildings are broadly associated with widespread semiologic and aesthetic values. This work focuses on the phase of quantitative physiognomic characterization of historic rural buildings. Such an approach calls for high-detail, systematic surveys of the main geometric features of buildings, thus often entailing considerable costs, which are also due to the high density of the rural built environment over wide regions in Europe. The general goal of this article is to define and test a repeatable, flexible, and efficient methodology that allows the results of the above-mentioned dimensional analyses to meet the precision standards of the model. With reference to an Italian study area, we define a stratified random sampling method for historic rural buildings. The stratification was based on the typological classification and location of the buildings. GIS implementation allowed us to calibrate the method and define a pilot sample suitable to carry out the analyses through photogrammetric surveys. The average values of length, width, and height of the sample buildings appeared to be differentiated among the classes identified, and certain significant volumetric arrangements were recognized. The analysis method proved suitable for the physiognomic investigations of historic rural buildings as defined within the FarmBuiLD research model.
