We report on and discuss records of five species new to the vascular flora of Croatia. Calamagrostis canescens was found near Đurđevac in remnants of fen vegetation, and we consider it a critically endangered species in the flora of Croatia. Agrimonia procera is native or archaeophyte in central Croatia and its discovery is in accordance with its earlier use as a medicinal plant. Amaranthus emarginatus is an exotic newcomer that was previously found in urban habitats on the north Adriatic coast. Carex vulpinoidea and Oenothera suaveolens were shown to be locally established species, in meadows along the Kupa River, and on the bars of the Drava River, respectively. In addition, we present new distributional and ecological data on two neophytes (Cardamine occulta, Humulus scandens) that were only briefly mentioned in earlier sources from Croatia.

The vascular flora of the geomorphological natural monument Crveno jezero, located in the Dalmatian hinterland, was studied during 2017 for the first time. A total of 149 plant taxa belonging to 52 families were recorded, with Asteraceae, Fabaceae, Lamiaceae, and Poaceae being the most abundant families. The dominance of Mediterranean, South-European, and Eurasian floral elements indicates that the study area is under the influence of both oceanic and continental climates, which is in accordance with the specific location of the study area. We noted a diversity of life form strategies, with the five main strategies having a share of at least 10% of the total number of species. Most species in the study area had competitive or stress-tolerant strategies, as well as the capacity for vegetative propagation, which was to be expected in this fairly unfavorable environment. No fewer than 15 recorded species are protected by law, including 11 endemic species, which represent 7.4% of the total flora. Most of the endemic species are Illyrian-Adriatic and Illyrian-Balkanic endemics. The results of the present study greatly contribute to the knowledge of the flora of Crveno jezero and the Imotski region, and they can be used as a basis for the future conservation of the area.

In the last decade of the 20th and in the early 21st century a new plant from East Asia, Cardamine occulta, was recorded in many European countries, and evaluated as a potential invasive species. Prior to our research, it had not been observed in Croatia or the neighbouring countries. During 2017, the first plants of C. occulta were discovered in plant nurseries in Zemunik Donji (near the city of Zadar), and in the city of Split. Since then, both sites have been monitored continuously, and the populations in both nurseries are still present and getting denser every year. In this work we aim to present a short history of the discovery, list newly-detected sites and establish some features (taxonomical peculiarities, plant description, distribution, growth and invasive preferences) of the species C. occulta to make its identification easier. Because of its invasive potential and morphological similarity with two other taxa distributed in Croatia, C. hirsuta and C. flexuosa, the determination key for all three taxa, as well as photos of C. occulta have been prepared. This will probably increase the chance of early detection of this species outside of cultivation.

The plant lists of Gladiolus, Crocus and other members of the Iridaceae family grown in the Botanical Garden from 1895 to 2021 are studied, with a supplement for the genus Iris, analyzed in 2019. The nomenclature, synonymy and origin of plant material were arranged. Lists of species grown in the last 126 years are constructed to show that throughout that period at least 448 taxa of wild and cultivated Iridaceae from 30 genera inhabited the Garden’s collections. Today we have 371 taxa out of 21 genera. Out of this number, the genus Gladiolus accounts for 35 taxa (formerly 50), Crocus 7 (formerly 27), while Iris includes as many as 291 species, cultivars and hybrids. The remaining 18 Iridaceae genera are represented by 38 taxa.

Authors:   Azuritweg 2, 70619 Stuttgart, Germany, Gumhalter Danijela
Published: August 2021

From 2016 to 2020 numerous surveys were undertaken to improve the knowledge of the pyraloid moth fauna of Biokovo Nature Park. On August 27th, 2020 one specimen of Psorosa mediterranella (Amsel, 1954) from the family Pyralidae was collected on a small meadow (985 m a.s.l.) on Mt Biokovo. In this paper, the first data about the occurrence of this species in Croatia are presented. The previous mention in the literature for Croatia was considered to be a misidentification of the past and has thus not been included in the checklist of Croatian pyraloid moth species. P. mediterranella was recorded for the first time in Croatia in recent investigations and, after other additions to the checklist have been counted, is the 396th species in the Croatian pyraloid moth fauna. An overview of the overall pyraloid moth fauna of Croatia is given in the updated species list.

Carbofuran is a broad spectrum carbamat insecticide which is used in various farm practices. An exposure of carbofuran has been reported able to induce Reactive Oxygen Species (ROS) or free radical in kidney. Free radical caused cells damage. The present study was designed to investigate the effect of carbofuran in kidneys histopathologic of mice pup whose dam were exposed by carbofuran during the lactation period. High levels of ROS can bind to various biomolecules such as proteins, lipids and nucleic acids so that carbofuran has a negative effect on tissue functions and structures. Free radical caused changes in the pathological conditions of the tissue including the kidneys. The dams were devided into four groups of five animals each. P0 animal group was received aquadest 0,1 ml per body weight (BW), P1 animal group was treated carbofuran at the dose of 1/16 LD50 (0,3125 mg per BW), P2 animal group was treated carbofuran at the dose of 1/8 LD50 (0, 625 mg per BW), and P3 animal group was treated carbofuran at the dose of 1/4 LD50 (1,25 mg per BW). The carbofuran was exposed via oral postnatal day 1st until 9th postnatal day after delivery. At postnatal day 10th, offspring were sacrified. The kidney of mice pup was collected and processed for microscopic examination with hematoxilin-eosin staining. Microscopic observations on the histology of the mice pup kidney showed an increase in the degree of kidney damage as an increase in the dose of carbofuran given to the dams. The results showed tubular changes in the form of tubular degeneration, inflammatory cell infiltration and tubular necrosis in the kidney of mice pups.

Blood-stain or blood splatter analysis when used properly can assist in establishing a chain of events linked to violent crimes (Bevel and Gardner, 2008). The methods used in detecting blood splatters in the field are chemical methods. Leucomalachite green is a colorimetric test which is used to test the presence of blood (Castro and Coyle, 2008). Takayama reagent is a confirmatory test for blood (Strassman, 1922). The aim of this research is to detect the blood splatter on cotton fabric after it has been dried for 1 day, 3 days and 5 days using Leucomalachite green and Takayama reagent. Cotton fabric was specifically chosen for this experiment with 3 different periods of drying. The unstained cotton fabric was cut into squares, and a blood sample was splattered on each piece. The fabrics splattered with blood were then dried for 1 day, 3 days and 5 days. The blood splatter was then tested using Leucomalachite green and Takayama reagent, and the results were noted afterwards. For the control, red food dye was dried for 1 day then tested with Leucomalachite green and Takayama reagent. The image results of the Leucomalachite green test are analyzed using ImageJ software 1.8.0_112 where the red, green and blue pixels are converted to grayscale. The image results of the Takayama test are graded based on the number and pattern of crystal. In conclusion, Leucomalachite green and Takayama reagent are able to detect cat blood splatter on the cotton fabric. Leucomalachite green produced a higher intensity/ darker colour as a result of an older sample, and the lower intensity/ lighter colour as a result of a fresher sample of the Leucomalachite green test. Takayama reagent produced a densely packed pattern of crystals as a result of an older sample, and the loosely packed pattern of crystals as a result of a fresher sample of the Takayama test.

This research aimed to test the feasibility of a geometrical optics instrument to identify the misconception and its causes. The instruments used in this research were question validation sheet and five-tier geometrical optics test (FIGOT) with 14 items of questions and consisted of 48 concepts tested. FIGOT obtained from the existing four-tier test research before which was then modified by adding one more tier about the causes of misconception. FIGOT validated by six experts, in which one the aspect assessed was the suitability of the items with alternative conceptions.  The analysis of construct validity tested using CVR (almost all items have a CVRAverage value of ≥ 0.67) and the reliability was using Cronbach’s Alpha (r ≥ 0.62 for each or both tier). The identification results processed using CDQ (Confidence Discrimination Quotient). The study was conducted in two public high schools located in Bandung and two public high schools located in Jakarta with 109 students (34 males and 75 females). The result showed that most senior high school students still experienced misconceptions related to the topic of geometrical optics, 17 misconceptions from 48 concepts about geometrical optics. The biggest percentage was 81% and CPM (Confidence of Percentage Misconception) was 4,75 about plane mirror. The most dominant causes of misconception in the material of geometrical optics were due to teachers, school books, and internet.

The main aim of sustainable development is to ensure an intelligible and long-lasting balance between the economy, society, and the environment. Sustainable tourism could only be successful if the inter-relationships between all three dimensions are accepted. In the limited number of research analyses, the focus of the research is on competition between tourist countries and destinations. This study has used Game theory to analyze the competition applies time-series data in selected neighboring countries measure of a VAR-based spillover index, developed by [1] to investigate the time-varying relationship between tourism and Gross Domestic Product. Each country analyzed Vector Error Correction (VEC) and Granger analysis to explore the causal short and long-term tourism and use a sample that spans from 1997 to 2019. From the main results of Cholesky, the total spillover index is 59.0% between Russia and Mongolia which suggests a moderate interdependence among the four variables. Findings indicate that neither China nor Mongolia have a short-run influence on tourism development. China's inbound tourism is affected in the long run by Mongolia's inbound tourism but not vice versa can be explained by the fact that the number of tourists visiting Mongolia would include China in their travels.

In this paper defines the consecutive sum of the digits of a natural number, so far as it becomes less than ten, as an arithmetic function called and then introduces some important properties of this function by proving a few theorems in a way that they can be used as a powerful tool in many cases. As an instance, by introducing a test called test, it has been shown that we are able to examine many algebraic equalities in the form of in which and are arithmetic functions and to easily study many of the algebraic and diophantine equations in the domain of whole numbers. The importance of test for algebraic equalities can be considered equivalent to dimensional equation in physics relations and formulas. Additionally, this arithmetic function can also be useful in factorizing the composite odd numbers.
Finding an Effective Treatment for Sustainable Chinese Language Learning in Japan: A Comparative Study on Motivation of Different Ages
Authors: Cai Qiao-Yu
Published: August 2021

Sustaining learners’ motivation to keep learning has been concerned for over 60 years in education and SLA. Most research focusing on Japanese university students has contributed lots of theoretical and practical developments, but research focusing on motivations of non-traditional adult learners and those under 18-year-old to learn Chinese is still little even though previous research findings have proved age is one of the key variables influencing learning besides nationalities and Chinese language levels. In order to find an effective treatment for sustainable Chinese language learning in Japan, this study utilized a survey method to analyze the types of Japanese learners’ motivation to learn Chinese via analysis of a moment structures (AMOS), and to compare the differences of the motivation via one-way ANOVA. This study revealed that Japanese learners’ motivation to learn Chinese consists of eight common types, which are “instrumental motivation”, “personal orientation”, “identified regulation”, “Chinese cultural productions”, “integrating into Chinese community”, “external regulation”, “social responsibility”, and “Chinese for academic purposes”. Also, there are similarities and differences existing in the eight motivation types among the Japanese children, adolescents, (non-) traditional adult learners of Chinese as a foreign language (CFL). The findings contribute the understanding of motivation types and differences among the four aged Japanese learners to teachers of teaching Chinese to speakers of other languages (TCSOL), and to future research further exploring how differently aged Japanese learners can have and use a higher motivation as a main drive to learn Chinese language as a lifelong business.

Published: August 2021

This paper deals with building envelope thermal performance through a comparative study of the use of two types of construction materials, such as CEB and cement blocks, in order to introduce the use of double walls in sustainable buildings' construction. The building envelope participates in providing thermal comfort to users and in the optimal management of building energy consumption. This study begins with a survey of public preferences for building materials used in Burkina Faso. The results indicate that 76% of the people surveyed opt for cement blocks over local materials.  Concerning the thermal and specific energy performance, three variants of building envelope were studied: CEB walls, cement blocks and the double-wall (CEB + Cement blocks). It appears that the CEB walls are more efficient than the cement block walls. The introduction of double envelopes leads to the thermal resistance of 357.37m².K/W and reduces the heat flow from 85.32% to 90.24% compared to the wall made with CEB and cement blocks. This approach, which consists in mixing construction materials for good thermal insulation, allows improving the envelope thermal performance and the overall building energy performance.

Avocado (Persea americana Mill.) is a plant widely found in tropical regions such as Indonesia. Currently, people only consume the avocado flesh and dispose of the seed. This study aimed to examine the antioxidant activity, isolate and identify the active antioxidant structure from avocado seed extracts. The trial was conducted from January to June 2021 at the Chemical Laboratory of Natural Substance, Research Center for Biotechnology, LIPI.  The avocado fruit used in this research was obtained from Cibitung Central Market, Bekasi. The solvents used in the extraction were n-hexane, ethyl acetate, 96% ethanol, and water with multilevel extraction. Antioxidant activity was tested using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical method. The structure of the active compound was determined using UV-Vis spectrophotometry, Fourier Transformation Infrared Spectroscopy (FTIR), and GCMS. The 96% ethanol extract had the highest antioxidant activity with EtOH.4.3.1 isolate as the most active antioxidant isolate with IC50 23,07±1,63 μg.ml-1. The identification results of isolate EtOH.4.3.1 of avocado seed extract with UV-Vis spectrophotometry, FTIR, and GCMS indicated 2-Ethylhexyl-4-methoxycinnamate acting as an antioxidant. Further analysis with Nuclear Magnetic Resonance (NMR) spectrometry of protons and carbon is required to determine the number and position of protons and carbon in the chemical structure.

The revegetation of areas impacted by iron mining may be hampered by a series of chemical and physical impediments exhibited by those areas. Physical problems, such as penetration resistance and steep slopes, may outweigh the chemical problems, such that both should be considered for soil recovery. This study aimed to evaluate the main soil attributes that are directly related to plant growth on areas affected by iron mining activities discussing possible solutions. For this purpose, chemical and physical attributes including penetration resistance on open pit mines, waste piles and native forest in Carajás Mineral Province were analysed. The results show that the open pits had low to medium levels of P and low levels of organic matter and of the micronutrients B, Zn and Cu. In the waste piles, the chemical parameters were less hindering than in the open pits. Soil penetration resistance in open pits was higher than in the waste piles and the forest; however, there was a reduction of up to 69% in soil resistance in open pits in the rainy season. The principal chemical problems observed in mine pits can be easily corrected, although the inclination of open pit slopes in combination with elevated soil density increase the risks of losses of fertilizers and seeds by runoff. Penetration resistance is the most serious problem for the development of plants in mine pits, although the use of irrigation water can help to maintain tolerable levels of resistance in soil for proper root growth of native species.

Hydrogen is a potential energy carrier for renewables that has a clean emission during the point of use. To implement hydrogen energy system in large-scale, a comprehensive hydrogen supply network should be built to supply the hydrogen with optimal infrastructure arrangement. Although the optimization of hydrogen supply chain has been extensively studied, the investigation of an integrated hydrogen-electricity supply chain is still lacking. Considering the interconvertibility of hydrogen and electricity, this study presents a spatial optimization framework that integrates geographical information system with mathematical modelling for the design and optimization of a photovoltaic-based hydrogen-electricity supply chain. The proposed framework allows the concurrent targeting of vehicle fuel and electricity demands as well as the identification of suitable locations for supply chain infrastructures. Case study results showed that the minimum cost of hydrogen-electricity supply chain is about 14.9 billion USD/y assuming two days of autonomy, and the cost of battery constitutes 43% of the total supply chain cost. When the days of autonomy is 8 and above, electricity storage in the form of hydrogen and reconversion through fuel cell is preferred.

Authors: Wang Xinye Serena , Magnuson William , Behl Pearl , Koval Dmitrii
Published: August 2021

Introduction: Atypical presentations of systemic lupus erythematosus SLE) with features outside of the 2012 Systemic Lupus International Collaborating Clinics (SLICC) criteria can make the diagnosis of SLE elusive. Case Presentation: We describe a case of a healthy 31-year old female who presented with syncope preceded by progressive headache, serositis, and generalized lymphadenopathy. CT-head and MR-venogram confirmed a cerebral venous thrombosis (CVT). Subsequent workup revealed high titers of antinuclear (ANA), anti-double stranded DNA (anti-dsDNA), anti-Smith (anti-Sm) antibodies, as well as low complement levels, lymphopenia and neutropenia. Diagnosis of SLE was confirmed by SLICC classification criteria. Antiphospholipid antibodies (APLA) were negative. While in hospital, she sustained a seizure secondary to the CVT. Conclusion: We discuss considerations for atypical SLE presentations by CVT (without APLA syndrome) and generalized lymphadenopathy, and the nuances of SLE diagnosis using existing classification criteria.

BackgroundThe prophylactic administration of tranexamic acid reduces the blood loss during procedures at high risk of perioperative bleeding. Several studies in neurosurgery, cardiac surgery, and orthopedics confirmed this finding. The aim of this prospective, double-blind, randomized study is to evaluate the effect of tranexamic acid on peri-and postoperative blood loss and on the incidence and severity of complications.Methods / DesignBased on the results of our pilot study, we decided to conduct this prospective, double-blind, randomized trial to confirm preliminary data. The primary end-point is to analyze the effect of tranexamic acid on perioperative and postoperative blood loss (decrease in hemoglobin levels) in robotic-assisted radical prostatectomy. The secondary end-point is to analyze the effect of tranexamic acid on postoperative complications. Additional end-point is to confirm the safety of tranexamic acid in robotic assisted radical prostatectomy.DiscussionNo study to date has tested the prophylactic administration of tranexamic acid in the beginning of robotic assisted radical prostatectomy. This study is designed to answer the question whether it might lower the blood loss after the procedure or increase the rate and severity of complications.Trial registrationThe trial was prospectively registered under title "Can the Prophylactic Administration of Tranexamic Acid Reduce Blood Loss After Robotic-assisted Radical Prostatectomy? (RARPEX)" on 25th March 2020 at ClinicalTrials.gov with the registration number NCT04319614.
