Opis:
Purpose: To determine the health and nutritional status of people in the Chittagong city corporation area of Bangladesh. Materials and methods: A face-to-face interview methodology was used for this survey. The study sites were located in 15 thanas of the Chittagong city corporation area. The study was also designed with interview questions closely related to health.Results: Among the total 620 respondents, 453 respondents were males and 167 respondents were females. 471(75.96%) of the total respondents had positive comments about the health status of their community. 169(27.52%) respondents had poor or fair appetites but the rest of them had good, very good or excellent appetites. 360(58.07%) of the respondents reported they had been eating a minimum of one fruit per day and 85(13.7%) people drank 5 to 8 glasses of water daily. 441(71.12%) of their diets more or less met daily vitamin and nutrient requirements and 338(54.51%) were nonsmokers. 407(65.64%) were married, and 388 (62.58%) were more or less satisfied about their sexual life. 441(71.12%) respondents performed physical exercise more or less habitually. A lower number of respondents had a major disease. For instance, 155(25%) suffered from high blood pressure, and 150(24.19%) suffered from diabetes. In the case of minor diseases, 399(64.35%) of the respondents had been suffering from GIT disease and 416(67.09%) were taking proton pump inhibitors or a H2 receptor blockers. 205(33.06%) respondents were taking antibiotics regularly.Conclusions: One third of the people had hypertension and diabetes. According to the biomedical concepts, peoples were not healthy. However, according to the ecological and psychological concepts of health, this survey proved that the people of the Chittagong city corporation area were comparatively healthy.

Opis:
We present a systematic study of late Paleocene macrofauna from methane seep carbonates and associated driftwood in the shallow marine Basilika Formation, Spitsbergen, Svalbard. The fauna is composed of 22 taxa, comprising one brachiopod, 14 bivalves, three gastropods, three crustaceans, and one bony fish. The reported fish remains are among the first vertebrate body fossils from the Paleogene of Spitsbergen. One genus is new: the munidid decapod Valamunida Klompmaker and Robins gen. nov. Four new species are described: the terebratulide brachiopod Neoliothyrina nakremi Bitner sp. nov., the protobranch bivalve Yoldiella spitsbergensis Amano sp. nov., the xylophagain bivalve Xylophagella littlei Hryniewicz sp. nov., and the munidid decapod Valamunida haeggi Klompmaker and Robins gen. et sp. nov. New combinations are provided for the mytilid bivalve Inoperna plenicostata, the thyasirid bivalve Rhacothyas spitzbergensis, the ampullinid gastropod Globularia isfjordensis, and the munidid decapod Protomunida spitzbergica. Thirteen taxa are left in open nomenclature. The fauna contains a few last occurrences of Cretaceous survivors into the Paleocene, as well as first occurrences of Cenozoic taxa. It is composed of chemosymbiotic thyasirid bivalves and background species common in the northern Atlantic and Arctic during the Paleocene. Our results provide no evidence for a Paleocene origin of vesicomyid and bathymodiolin bivalves typical for Eocene and younger seep environments; instead, the Paleo cene seeps of the Basilika Formation are more similar to their Late Cretaceous equi valents rich in thyasirids.

Opis:
The contents of the superfamily Platanistoidea, an early-diverging lineage comprising extinct species and a single extant representative of South Asian river dolphin (Platanista gangetica), remain controversial. We describe here a partial skull and associated tympano-periotic bones identified as a new genus and species, Aondelphis talen gen. et sp. nov., collected in the lower levels of the Gaiman Formation (early Miocene), in Patagonia (Chubut Province, Argentina). Aondelphis is the first Patagonian platanistoid species named in almost a century. Phylogenetic analyses suggest Aondelphis talen gen. et sp. nov. and a taxon from New Zealand (cf. Papahu ZMT-73) are basal Platanistoidea sensu lato. Unambiguous synapomorphies related to the ear bones allowed us to determine its phylogenetic position. Aondelphis talen markedly differs from the other well-known early Miocene Patagonian platanistoid Notocetus, suggesting the coexistence of at least two different morphotypes that may have occupied different ecological niches at that time. The putative close relationship with a species from New Zealand indicates there was a rapid diversification and widespread distribution of the group in the Southern Hemisphere during the early Miocene. The description of new species and revision of historical records of Patagonian platanistoids can help shedding light on cetacean assemblages of the Patagonian sea during this epoch.

Opis:
The study area is located in the North-Eastern part of the Nile Delta, northern of Ismailia canal and western Suez Canal. It comprises an area of about 3,058.8 km 2 (728,285.38 feddans). This work aims to identify the main physiographic units and its features, as well as emphasise the importance of combining soil taxonomy (2014) and WRB classification (2022) systems. Two main physiographic units were distinguished in the study area according to the previous studies, interpretation of satellite image and digital elevation model (DEM) as well as field observations; the first consists of fluvio-marine flats and the second river terraces which include the fluvial and deltaic origin. According to field morphological descriptions as well as chemical and physical analyses, representative profiles are classified by using both Soil Taxonomy and WRB systems. The current study is the third manuscript to emphasise the importance of using both systems together in order to obtain maximum possible characteristics of the earth. Below are examples that illustrate this importance. Soils of profile No. 4 which represent the fluvio-marine soils are classified according to soil taxonomy as follows: Typical Haplosalids, fine silty, mixed, thermic. While these soils are classified according to WRB as follows: Fluvic Sodic Solonchaks (Siltic/Loamy/Clayic, Chloridic, Evapocrustic, Ochric, Hypersalic). Soils of gypsiferous which represent soils of profile No. 6 are classified according to Soil Taxonomy as: Gypsic Aquisalids, loamy over sandy, mixed, thermic, whereas the application of the WRB system reveals the following: Fluvic Calcic Gypsic Sodic Gleyic Solonchaks (Loamic, Chloridic, Hypersalic).

Opis:
The Phase Locked Loop (PLL) has become an important part of electrical systems. When designing a PLL, an efficient and reliable simulation platform for system evaluation is needed. However, the closed loop simulation of a PLL is time consuming. To address this problem, in this paper, a new PLL model containing both digital and analog parts based on SystemC/SystemC-AMS (BETA version) is presented. Many imperfections such as Voltage Control Oscillator (VCO) noise or reference jitter are included in this model. By comparing with the Matlab model, the SystemC/SystemC-AMS model can dramatically reduce simulation time. Also, by comparing with Analog Devices ADI SimPLL simulation results, Cadence simulation results and real measurement results, the accuracy of the SystemC/SystemC-AMS model is demonstrated. The paper shows the feasibility of a unified design environment for mixed-signal modelling based on SystemC/SystemC-AMS in order to reduce the cost and design time of electrical systems.

Opis:
Recently lack of sustainable management for the reservoir watershed becomes a predicament for the water issues in Taiwan. The study tried to recognize the framework of the sustainable management of the Taiwan reservoir watershed and its key factors by using the analytic hierarchy process and the Delphi method. Through the identification questionnaires and the CVM (contingent valuation method), it also discussed the gap of expert and public for the identification of satisfaction, environmental protection and the potential value for the recent reservoir watershed. However, the results showed that the “natural stability” is the significant factor in the first level and the “Nature resources conservation” and “Water storage amount” are the most important factors for the detailed level. In addition, the expert opinions were not proved by public identification, and the present governance budgets are too low to respond to the potential values of public expectancy.
W pracy przedstawiono wyniki badań przeprowadzonych dla określenia hierarchii ważności czynników ekologicznych, ekonomicznych i socjalnych związanych ze zrównoważonym zagospodarowaniem zlewni zbiorników wodnych na Tajwanie. W badaniach zastosowano metodę ankietową, w której respondenci stosując pięciostopniową skalę mieli wskazać ważność 22 określonych przez ekspertów czynników związanych z ochroną i zrównoważonym korzystaniem z zasobów środowiska, wpływających na standard życia mieszkańców oraz możliwości rozwoju gospodarczego na obszarze zlewni zbiorników wodnych. Stwierdzono, że najważniejsze znaczenie dla ludności mają czynniki ekologiczne, w szczególności zapewnienie stabilności przyrodniczej poprzez zachowanie bioróżnorodności oraz ochrony zasobów naturalnych, w tym ilości retencjonowanej wody.

Opis:
Based on a three-year field experiment under controlled condition in Ji’nan, China, the effects of peanut growth on the variation in the abundance and community structure of ammonia oxidizing bacteria (AOB) and archaea (AOA) before and after peanut growth were investigated through quantitative PCR and cluster analysis of terminal-restriction fragment length polymorphism. Our results show that the community composition of AOA and AOB was greatly affected by the peanut growth leading to the decreased abundance of AOA and increased abundance of AOB. Furthermore, AOA and AOB community structures varied before and after peanut growth. Phylogenetic analysis indicated that all AOA and AOB community sequences were clustered into the uncultured group. Altogether, the results suggested that the abundance of AOA and AOB in soil and their community compositions can be greatly affected by the peanut growth.

Opis:
This study investigates the acaricidal, ovicidal, and repellent effects of the Tagetes patula Linn. (Asteraceae) leaf extract against both the adult female and egg stages of Tetranychus urticae Koch (Trombidiformes: Tetranychidae) under laboratory conditions. The Tagetes patula ethanolic leaf extract [TpEtOH70%] was screened for adulticide and ovicide bioassays in order to consider its acute toxicity. One sublethal concentration was used to assess egg-laying capacity (fecundity), repellent, and oviposition deterrent activities. The chemical characterization was conducted by gas chromatography-mass spectrometry (GC-MS) analysis to identify the TpEtOH70% bioactive components. Results showed that the LC50 value of TpEtOH70% leaf extract predicted by Probit analysis against T. urticae adult females at 24 h was 0.99%.The TpEtOH70% leaf extract showed a significant toxic effect as the highest mean mortality rates (± SE) of the treated adult females was 88.9 ± 3.7%. However, the TpEtOH70% leaf extract was insignificant in affecting the egg-laying capacity of the adult females treated with a sublethal dose of 0.5% even after 72 h. The TpEtOH70% leaf extract was classified repellent since the repellent index (RI) value was lower than 1 – SD. In addition, it had a high oviposition deterring effect based on a 100% reduction of the total number of eggs. The TpEtOH70% leaf extract had a significant ovicidal effect on T. urticae eggs, with 56.04% reduction in hatching. Five bioactive compounds from various classes of phytochemicals were identified in the TpEtOH70% leaf extract and the major compound was phytol (62.72%). This pioneering investigation reveals the adulticidal, ovicidal, and repellent activities of the TpEtOH70% leaf extract against T. urticae. A combination of multiple modes of action of different plant components may act alone or in synergism to delay the development of mite resistance.

Opis:
Allelopathy is a complex phenomenon which depends on allelochemical concentrations. So, two pot experiments were carried out to investigate the allelopathic effect of alcoholic fresh shoot extract of Eruca sativa (foliar spray) and E. sativa shoot powder (mixed with soil) on Pisum sativum plants and two associated weeds, Phalaris minor and Beta vulgaris. The experiments were conducted in the greenhouse of the National Research Centre, Giza, Egypt during two successive winter seasons (2016–2017 and 2017–2018). Ten treatments were applied in this study. Four treatments were applied before sowing, that E. sativa shoot powder was mixed with the soil at rates of 15, 30, 45 and 60 g ⋅ pot–1. The other four treatments of E. sativa alcoholic fresh shoot extract were sprayed twice on both plants and weeds at 5, 10, 15 and 20% (w/v) concentrations. Additionally, two untreated treatments, healthy (P. sativum only) and unweeded (untreated infested P. sativum plants with weeds) were applied for comparison. The results indicated that both alcoholic extracts and powder reduced growth of both weeds. Moreover, there was a direct relationship between concentration and weed reduction. Eruca sativa alcoholic extracts increased yield parameters of P. sativum plants. The maximum yield attributes were recorded by spraying of E. sativa alcoholic extract at 20%. On the other hand, it was clearly noticed that the high powder rates affected negatively P. sativum yield parameters. But the lowest powder rate (15 g ⋅ pot–1) stimulated P. sativum yield parameters as compared to unweeded treatment. Chemical analysis of E. sativa shoot powder ensured that the abundant amount of glucosinolates (9.6 μmol ⋅ g–1) and phenolic compounds (46.5 mg ⋅ g–1) may be responsible for its allelopathic effect. In conclusion, spraying of alcoholic fresh shoot extract of E. sativa at 20% (w/v) and mixing E. sativa shoot powder at 15 g · pot–1can be applied as natural bioherbicides for controlling weeds.

Opis:
The association between physiologically dependent pharmacokinetic parameters (CLB, T1/2β, Vdss) of marbofloxacin and body weight was studied in eight animal species based on allometric equation Y = aWb, where ‘Y’ is the pharmacokinetic parameter, ‘W’ is body weight, ‘a’ is allometric coefficient (intercept) and ‘b’ is the exponent that describes relation between pharmacokinetic parameter and body weight. The body clearance of marbofloxacin has shown significant (P<0.0001) relation with size (Bwt) in various animal species. However, half-life and volume of distribution were not in association with body weight. Although half-life and volume of distribution were not in a good correlation with body weight, statistically significant association between the body clearance and body weight suggests validity of allometric scaling for predicting pharmacokinetic parameters of marbofloxacin in animal species that have not been studied yet. However further study considering large sample size and other parameters influencing pharmacokinetics of marbofloxacin is recommended.

Opis:
Purpose: In this study, the free vibration analysis of functionally graded materials (FGMs) sandwich beams having different core metals and thicknesses is considered. The variation of material through the thickness of functionally graded beams follows the power-law distribution. The displacement field is based on the classical beam theory. The wide applications of functionally graded materials (FGMs) sandwich structures in automotive, marine construction, transportation, and aerospace industries have attracted much attention, because of its excellent bending rigidity, low specific weight, and distinguished vibration characteristics. Design/methodology/approach: A mathematical formulation for a sandwich beam comprised of FG core with two layers of ceramic and metal, while the face sheets are made of homogenous material has been derived based on the Euler–Bernoulli beam theory. Findings: The main objective of this work is to obtain the natural frequencies of the FG sandwich beam considering different parameters. Research limitations/implications: The important parameters are the gradient index, slenderness ratio, core metal type, and end support conditions. The finite element analysis (FEA), combined with commercial Ansys software 2021 R1, is used to verify the accuracy of the obtained analytical solution results. Practical implications: It was found that the natural frequency parameters, the mode shapes, and the dynamic response are considerably affected by the index of volume fraction, the ratio as well as face FGM core constituents. Finally, the beam thickness was dividing into frequent numbers of layers to examine the impact of many layers' effect on the obtained results. Originality/value: It is concluded, that the increase in the number of layers prompts an increment within the frequency parameter results' accuracy for the selected models. Numerical results are compared to those obtained from the analytical solution. It is found that the dimensionless fundamental frequency decreases as the material gradient index increases, and there is a good agreement between two solutions with a maximum error percentage of no more than 5%.

Opis:
Wild raspberry (Rubus idaeus L.) is abundantly grown and widely distributed in temperate regions of lower Himalayan range which represents rich biological diversity for raspberry. Thirty accessions were explored from three different locations of Azad Jammu and Kashmir (Pakistan), several traits were visualized at sampling locations and some characteristics were evaluated and quantified after harvest of leaf and fruit samples. The accessions differed greatly in growth habit, blooming time, intensity of flowering, fruit setting, ripening time, productivity, fruit shape and color. Concerning quantitative characteristics, significant differences were found in plant height, leaf length and width, number of braches per plant, duration of flowering, fruit setting percentage, days to maturity, fruit length, width and weight among the samples collected from different locations. Ripe fruits were evaluated for their chemical composition i.e. moisture, carbohydrates, protein, fat, fiber, ash, TSS, acidity, pH and mineral (K, Ca, Na, Fe, Cu, Zn, Mn, Pb, and Cr) contents. The location also had significant effect on chemical composition of ripe fruits.
Malina właściwa (Rubus idaeus L.) jest często hodowana i szeroko rozprowadzana w umiarkowanych rejonach niższego pasma Himalajów, które reprezentuje bogatą różnorodność biologiczną malin. Zbadano trzydzieści próbek z trzech różnych miejsc Azad Jammu i Kaszmiru (Pakistan), dokonano wizualizacji kilkunastu cech w miejscach pobierania próbek oraz oceniono i ilościowo określono kilka cech po zebraniu próbek liści i owoców. Próbki znacznie różniły się wzrostem, czasem kwitnienia, intensywnością zakwitania, zawiązywaniem owoców, czasem dojrzewania, plonowaniem oraz kształtem i kolorem owoców. Jeśli chodzi o cechy ilościowe, to stwierdzono istotne różnice w wysokości roślin, długości i szerokości liści, liczbie gałązek na roślinie, długości kwitnienia, procencie zawiązywanych owoców, liczbie dni do dojrzałości, długości owoców, szerokości i wadze pomiędzy próbkami zebranymi z różnych stanowisk. Dojrzałe owoce oceniono pod względem składu chemicznego, tzn. wilgotności, zawartości węglowodanów, białka, tłuszczu, błonnika, popiołu, TSS, kwasowości, pH oraz zawartości minerałów (K, Ca, Na, Fe, Cu, Zn, Mn, Pb oraz Cr). Stanowisko także miało istotny wpływ na skład chemiczny dojrzałych owoców.
