Authors: Gao Denghui , Zhao Kuanyao , Ma Baohong , Han Zhiping , Fan Jifei
Published: August 2023

The negative skin frictional caused by loess collapse will decrease the bearing capacity of single pile, which is essential to the design of pile foundations in loess areas. In this study, a method for estimating the subsidence of soil layer at any depth is firstly proposed based on the total self-weight collapse value. Secondly, a new load transfer constitutive model for pile-soil interface is developed, which considers the nonlinear stress-strain relationship and the ultimate shear strength of soil. Then, a load transfer calculation model for pile foundation is established, which can calculate the pile axial force, the pile skin frictional, neutral point position and the settlement of a single pile. The calculation results are compared with the test data that obtained from a pile foundation on-site immersion test and the effectiveness of the calculation method is verified well. This calculation method may be useful for designing pile foundations in collapsible loess regions.
Biochar as a water protection tool in peatland forestry – nutrient recovery from runoff water
Authors:   University of Eastern Finland, Faculty of Science, Forestry and Technology, School of Forest Sciences, Kakaei Lafdani Elham
Published: August 2023

Water quality is significantly affected by the forest logging activities that are carried out in drained peatlands, which causes a notable enhancement in sediment loading and nutrient export to water bodies. Furthermore, the seasonal fluctuations in nutrient concentrations in the runoff further underscore the need for efficient water protection tools in peatland forestry. To address these issues, biochar-based adsorption methods can potentially offer an effective alternative for water protection in peatland forestry. The current thesis investigates the potential for adsorption-based nutrient recovery from clear-cut peatland runoff water using Norway spruce and Silver birch biochars. In particular, the aim is to i) study the adsorption characteristics in relation to biochar properties and nutrient compounds in runoff waters in a small-scale laboratory experiment (Paper I); ii) investigate the adsorption characteristics of nitrogen (N) compounds from runoff water in a meso-scale laboratory experiment that utilises biochar reactors (Paper II); and iii) investigate the dynamics of biochar adsorption and desorption under fluctuating total nitrogen (TN) concentrations in runoff water (Paper III). Biochar made from birch and spruce were shown to efficiently adsorb N compounds from the water. Across all experiments, the TN content declined significantly, irrespective of the scale, or whether the runoff volume ranged from litres (I and III) to hundreds of litres (II). Furthermore, the TN content at the beginning of the experiment declined at the fastest rate. The results indicate that cases of relatively low adsorption capacity were attributed to the low initial TN concentrations in the water. In addition, TN adsorption occurs above a threshold concentration in natural runoff water. The spruce did not adsorb TN when the concentrations in the runoff water fell below 0.4 mg L-1. In this thesis, biochar emerges as a compelling water protection solution, particularly in regions where clear-cut peatlands release substantial quantities of nutrients.
Adsorptive Removal of Hazardous Cadmium(II) Ions from Synthetic Wastewater using Acid-Treated Algal Biomass Vaucheria sp.
Authors: RASTOGI ARSHI
Published: August 2023

The purpose of this investigation was to examine the ability of acid-treated Vaucheria sp., to remove hazardous cadmium(II) ions from  synthetic wastewater. The impact of variables such as solution pH, adsorbent dosage, initial metal ion concentration, alga-Cd(II)  contact duration and temperature were examined via batch experiments. Using Langmuir, Freundlich and Temkin adsorption models, the equilibrium isotherm constants were calculated. The equilibrium data were found to be more compatible with the Langmuir model. At pH 5, 0.6 g of algal dosage, an equilibrium time of 70 min and a temperature of 318 K, the maximal adsorption capacity achieved by Vaucheria sp. biomass for Cd(II) was 92.59 mg/g. Adsorption kinetics were analyzed using both the pseudo-first-order and pseudo-second-order models, with the latter model demonstrating to be more suitable for the adsorption process by comparing R2 values. The process was determined to be endothermic (ΔHº > 1) and spontaneous (ΔGº < 1) by analyzing the thermodynamic parameters. The  biomass was pre-treated to a variety of chemicals in order to improve metal sorption capacity and it emerged that acid pretreatments significantly boosted the metal sorption capacity. Overall, the findings suggest that acid-treated Vaucheria sp. might be a cost-effective and beneficial adsorbent biomass for removing Cd(II) metal ions from synthetic wastewater.

Published: August 2023

Schiff bases such as 4-{[(2-hydroxyphenyl) methylidene]amino} benzoic acid analogues (SB1-SB3) have been produced by the condensation of mole equivalent of 4-amino benzoic acid and various substituted salicylaldehyde. It has given good yield. The synthesized compounds (SB1-SB3) were analyzed by FT-IR, 1H-NMR and Mass spectroscopy techniques. Light emitting properties of the compounds have been studied by photoluminescence (PL) and diffuse reflectance (DR) spectra. Photoluminescence spectra of the compounds SB1-SB3 revealed that these molecules emit light from bright yellow to orange red color following exposure to UV light. From diffuse reflectance spectra, the measured optical band energy for SB1-SB3 was found to be 2.14eV, 2.06eV and 2.26eV respectively. The 3D surface view of scanning electron microscope (SEM) of SB1-SB3 have also been studied. This study revealed that Schiff base derivatives of 4-amino benzoic acid analogue molecules become promising material for light emitting devices. Antibacterial study of these compounds by Kirby-Bauer diffusion method revealed the antibacterial activity . This showed these compounds can be used as antibacterial compounds.

Authors: Chandran A Saritha
Published: August 2023

Polyaniline/Polyaniline coated short nylon fibre/natural rubber (PANI/PANI-N/NR) CPCs and PANI/NR CPCs were prepared by mechanical mixing on a two-roll mill. PANI-N provides both conductivity and good mechanical properties to the CPCs. Such CPCs with enhanced mechanical properties are expected to find many device applications. The frequency and temperature dependence of dielectric properties of PANI, NR, PANI/NR and PANI/PANI-N/NR CPCs in the frequency range 0.1 to 8 MHz and in the temperature range 303 to 393 K, were investigated. Different theoretical equations and mixture equations were applied to fit the observed dielectric data of the CPCs.
Effect of H2O2 Concentration on Morphology, Reflectivity and Wettability of Si Nanowalls Prepared by Metal Assisted Chemical Etching
Authors: Behara Anil Kumar , R. N. Viswanath , Mathews Tom
Published: August 2023

A facile and low cost method, metal assisted chemical etching was used to prepare silicon (Si) nanowalls atop the Si wafer, where the  effect of etchant solution concentration (H2O2 concentration) on the morphology, reflectivity and wettability of the fabricated Si nanowalls is investigated. The morphological and structural studies by scanning and transmission electron microscopy revealed the Si  nanowalls prepared at both low and high H2O2 concentration are smooth, nonporous and single crystalline, where the increase of  H2O2 concentration only changes the morphology from isolated nanowall structure to agglomerated nanowall structure. The height of nanowalls also increases with increase in H2O2 concentration and follows a linear behaviour with an etching rate of 5697 nm/M.  The reflectance study shows that the reflectance is extremely low over broad wavelength range (300-1100 nm) for Si nanowalls,  compared to that of planar Si wafer. The increase of H2O2 concentration significantly changes the wavelength dependence of the  reflectance spectrum. The wettability studies show that SiNWs prepared at low H2O2 concentration exhibit hydrophobicity in contrast  to the hydrophilicity of planar Si wafer, where the increase of H2O2 concentration to very high value changes the hydrophobicity of SiNWs to hydrophilicity as similar to planar Si wafer.

Published: August 2023

The adsorption behaviour of natural clay (NC) and thermal activated clay (TAC) mineral of the Panchanganga river flood zone sedimentfor levofloxacin (a class of fluoroquinolone antibacterial drug) has been studied. The isotherm and kinetic studies were performed using the batch technique. The results showed that TAC has 72.6% removal efficiency comparatively higher than NC, which is 62.8% at  120 min, pH = 7, dosage 0.40 g/L and Initial concentration of 18.69 mg/L. The kinetic and isotherm results indicate the adsorption of levofloxacin on NC and TAC follows Freundlich isotherm suggesting multilayer sorption and chemisorption as a rate-limiting step  during the process. A plausible mechanism is proposed for the interaction of NC and TAC with levofloxacin from the results of the  adsorption study. The negative free energy change and positive enthalpy change indicated that the adsorption process is spontaneous  and endothermic.
Preparation and Characterization of Cattail Cellulose Films as Environmentally Friendly for Drug-Controlled Release System
Authors: SRIHANAM P. , KHAMKON S.
Published: August 2023

The objective of this work was to extract cellulose from cattail plants by treatment with 10 % (w/v) sodium hydroxide for 3 h at 80 ºC and bleached with 2% (v/v) sodium hypochlorite for 1 h. The sample was cut with 1% (v/v) sulfuric acid for 1 h to obtain 27.88% cellulose. The extracted cellulose was then prepared as films by casting method in a petri dish. The cellulose films were light brown and transparent with random direction of an orientation. The cellulose film increased transparency and flexibility by adding glycerol. The FTIR results clearly revealed the cellulose functional groups and some peaks being shifted when mixed glycerol. The cellulose films have a maximum decomposition temperature (Td,max) of 310-340 ºC and the decomposition temperature decreases slightly when mixed with glycerol. Mixing methylene blue, a sample hydrophilic drug, the cellulose films have increased their texture brittle and found micro-porous on surfaces. In addition, the differences in peaks of the cellulose functional groups were also observed. These might be caused by the interaction formation of methylene blue functional groups and cellulose. The interaction resulted in an increase in the Td,max of the films. The release of the methylene blue pattern concerned the amount of mixed methylene blue. These results can be used as a basis for extracting cellulose from cattail plants and preparing cellulose films for specific applications such as drug-controlled release system.

Published: August 2023

A simple sol-gel approach was used to synthesize TiO2 nanoparticles and its composite TiO2-PEG (TPG) using polyethylene glycol  (PEG). The synthesized samples were characterized by XRD, SEM -EDX, TEM, UV-DRS, photoluminescence, Raman, XPS and BET-surface  area techniques. The development of non-toxic, cost-effective, biocompatible and efficient polymeric nanocomposite increases the mechanical, thermophysical and physico-chemical properties of prepared nanomaterials. PEG affected the reaction with the  crystallization process of the prepared titania nanoparticles to a great extent. The antibiotics ciprofloxacin and norfloxacin of fluoroquinolone class are widely used to treat certain bacterial infections and at the same time their residues generate serious health  issues due to the lack of proper waste water treatment systems thus causing environmental pollution. The present study is thus focused on synthesizing efficient titania PEG nanocomposite to enhance the photocatalytic degradation of antibiotics in both solar and  visible light. Efficiency of degradation was achieved maximum upto 74% with TPG and 64% with pure TiO2 nanoparticles for ciprofloxacin in visible light, similarly the degradation of norfloxacin was achieved 65% with TPG and 57% with TiO2 nanoparticles.  Sunlight irradiation resulted in the degradation of ciprofloxacin to 80.2% with TPG and 77% with TiO2 nanoparticles whereas it was  78.7% with TPG and 68.6% with TiO2 nanoparticles for the degradation of norfloxacin. These results indicate that the catalyst TPG  showed higher activity in presence of solar and visible light than TiO2 nanoparticles. Recyclability was also studied showing the stability of the photocatalyst used even after five successive runs.

An easy and convenient approach has been adopted to synthesize a new series of chromene/[1,2,3]triazole hybrid derivatives involving Cu(I) catalyzed alkyne-azide 1,3-dipolar cycloaddition and a single step multicomponent reaction. The novel synthesized compounds (8a-l) were screened for cytotoxicity against three tumour cell lines i.e. MCF-7, PC-3 and HeLa using reference drug doxorubicin. Compound 8j (m-acetyl) showed an outstanding activity against all the three cell lines with IC50 values of 2.67 ± 0.03, 3.13 ± 0.03 and 3.05 ± 0.05 μM respectively. Compound 8k (p-acetyl) also exhibited good activity with IC50 values of 3.16 ± 0.05, 4.68 ± 0.03 and 3.81 ± 0.02 μM and the values are closer to doxorubicin IC50 values. The rest of the synthesized compounds have displayed good to moderate activity compared to reference drug. Molecular docking simulations of compounds 8b, 8f and 8j exhibited an excellent binding interactions against the crystal structure of epidermal growth factor receptor (EGFR).
NABL Accreditation - Advantages and Disadvantages and Its Process in India
Authors: Ravi Ranjan Singh  , Kumari Pallavi
Published: August 2023

BACKGROUND

Accreditation is a means of self-regulation and peer review adopted by an institution or an organization. It is a voluntary process of being certified as meeting minimum requirements designated by an accrediting agency. ISO 15189 standard is an international standard that specifies requirements for quality management in medical laboratories. It is intended to promote the quality and competence of medical laboratories and to provide a framework for continual improvement. The National Accreditation Board for Testing and Calibration Laboratories (NABL) operates as an autonomous organization functioning under the governance of the Department of Science and Technology, Government of India. The primary objective of this initiative is to offer an independent evaluation of the proficiency and excellence in testing and calibration laboratories affiliated with governmental authorities, industry associations, and the private sector. The NABL provides laboratory accreditation services adhering to the ISO 15189 guidelines. Although there exist certain limitations to the accreditation process such as financial expenses, time constraints, stringent regulations, and an emphasis on adherence rather than enhancement, the advantages of accreditation generally outbalance these challenges. Accreditation serves as a means of providing guarantee with respect to the dependability and precision of laboratory outcomes, a fundamental imperative for a multitude of crucial purposes which include but are not limited to the realm of healthcare, environmental evaluation, and product safety assessment.

Published: August 2023

This contribution aims to compare the thermal interruption performance of pure CO2with a mixture of CO2/C4F7N. Measurements primarily show higher interrupting capability for amixture with C4F7N. Detailed analysis shows a distinct difference in the failure mechanism which forCO2/C4F7N is thermal failure and for CO2 mostly “hot dielectric” failure. The difference in the failuremechanism is relevant for the test duties with the most severe TRV. The influence of ablated nozzlematerial on the interruption process can be ruled out.

Oxigenação pulpar avaliada pela oximetria de pulso em pacientes submetidos à radioterapia para tratamento do câncer bucal
Authors: Veloso Heloísa Helena Pinho , Alves Yuri Barbosa , Pinto Morgana Elizete Silva , Carvalho Gabriel Garcia de
Published: August 2023

Introdução: Artigos sugerem que o fluxo sanguíneo e a sensibilidade da polpa dentária podem ser prejudicados em pacientes submetidos à radioterapia (RT) para tratamento do câncer bucal. O oxímetro de pulso (OP) surge como uma alternativa promissora na determinação da vitalidade pulpar, fornecendo dados confiáveis para uma caracterização abrangente do estado pulpar. Objetivo: Investigar a saturação de oxigênio (%SpO2) da polpa dentária em pacientes com tumores malignos bucais imediatamente após RT e seis meses depois. Métodos: Dois estudos foram realizados para avaliar a influência da radioterapia de cabeça e pescoço na oxigenação da polpa dentária. No estudo I, a oxigenação pulpar foi avaliada por oximetria de pulso em pacientes imediatamente após RT, e o estudo II investigou o mesmo parâmetro após seis meses de RT. Sessenta pacientes foram incluídos em cada estudo: grupo experimental, pacientes em sessão final de RT (I) ou pacientes que terminaram RT há seis meses (II); e grupo controle, pacientes que nunca passaram por RT. O oxímetro de pulso foi utilizado para avaliar a %SpO2 em dois dentes (n=60) por paciente. Os dados foram submetidos à análise estatística para identificar se as taxas médias de SpO2 obtidas nos grupos testados eram diferentes entre si. Resultados: O teste t de Student mostrou diferenças estatisticamente significativas para a %SpO2 pulpar em ambos os estudos, ao comparar os grupos controle e experimental, mostrando que a RT reduz as taxas de SpO2 (12%) durante o tratamento do câncer, e a saturação de oxigênio não volta aos níveis normais após seis meses de RT (p<0,001). Também foi detectada diferença estatisticamente significativa na comparação dos grupos experimentais dos estudos I e II. Os pacientes não apresentaram qualquer efeito adverso ou qualquer queixa relacionada ao uso do oxímetro. Conclusão: A radiação ionizante utilizada no tratamento do câncer bucal leva a uma diminuição da saturação de oxigênio da polpa dentária. Esse impacto é maior imediatamente após a RT do que após seis meses da RT. Seis meses após a RT não foram suficientes para recuperar a SpO2 ao mesmo nível de um paciente que nunca foi submetido à RT.

This experiment was designed to investigate the effects of different levels of copper–methionine chelates and alfalfa powder on egg yolk cholesterol content, egg quality, and performance in laying hens. In this experiment, a total of 100 laying hens (Nick Chick strain, from 109 to 117 weeks of age) were arranged into five experimental treatments, consisting of 2 different dietary alfalfa powder and 2 different copper chelate levels in a (2x2) factorial completely randomized design (CRD). The treat-ments groups included: T1 Control (Corn and soybean meal), treatments T2 (3% alfalfa powder+50 mg/kg copper-methionine chelate), T3 (3% alfalfa powder+100 mg/kg copper-methionine chelate), T4 (6% alfalfa powder+50 mg/kg copper-methionine chelate) and T5 (6% alfalfa powder+100 mg/kg cop-per-methionine chelate). The results of this study have shown that, different levels of alfalfa powder and copper-methionine chelate in laying hens diet except feed conversion ratio and shell-less eggs, oth-er performance parameters were not substantially affected by the level of 3% alfalfa powder through-out of experimental period (P>0.05). Moreover, different levels of alfalfa powder and copper-methionine chelate except egg yolk color had no significant effect on internal and external egg quality traits during the whole experimental period (P>0.05). As well as, the egg yolk color index was signifi-cantly increased by increasing the level of alfalfa powder in the laying hens’ diet (P<0.001). The high-est egg yolk color index was observed in treatment 5 which (containing 6% alfalfa powder+ 100 mg / kg copper-methionine chelate in per kg of diet). Meanwhile, the treatment group that received (6% al-falfa powder+100mg/kg copper- methionine chelate) the egg yolk cholesterol concentration was signif-icantly decreased compared to the control group (P<0.001). Therefore, addition of alfalfa powder and copper methionine chelate to the diet of laying hens reduced egg yolk cholesterol and increased egg yolk color.

Utilization of health services by pregnant and postpartum women can save women from the incidence of maternal death and severe complications during pregnancy and postpartum. Several factors that directly contribute to the utilization of health services are decision making and sources of information obtained by pregnant and postpartum women regarding the utilization of health services. This study aims to analyze gender equality in decision making on the use of health services in urban and rural areas of Indonesia. This study used a mixed-method approach from primary data and a literature review. The target in this article was pregnant women and postpartum mothers who were spread out in several health centers in Surabaya City and Bojonegoro Regency with a total of 175 respondents who were calculated using the proportion estimation formula. Data analysis used univariate and bivariate analysis. The results showed that the wife in terms of the number of frequencies dominated in making decisions on the use of health services (92.5%). In addition, when the decision maker is the husband, all postpartum mothers (100%) will take advantage of health services. Related to the source of information that many respondents chose in providing information related to pregnancy health for the use of health services, it was health workers (86.3%) compared to other media. The wife's decision is a determinant in making decisions about the use of health services. On the other hand, husband’s support as a decision maker can also influence his wife to take advantage of health services.

The used indicators were traders/employees, visitors, market buildings, garbage disposal sites, drainage ditches, toilets, places to sell food and groceries, control of disease-carrying animals, parking lots. However, the level of density of flies was still met the requirements. Conclusion: Poor hygiene and sanitation in the working area of Karangayu Market Regional Technical Implementation Unit, Semarang City, can increase the risk for disease transmission if it is not resolved.
Lidská práva a pravoslaví: přehled a vyhodnocení současné debaty
Authors: Širka Zdenko
Published: August 2023

In the Orthodox world, the debate on human rights has been one of the most interesting in recent years. There is an influential tendency among Orthodox priests, monks and laity to completely reject the idea of human rights as a mere Western invention without any cultural or spiritual basis among Eastern Christians. The critical problems are to be found in the different understanding of human dignity and the resulting emphasis on freedom or morality. Our task and question, therefore, is to identify the key points in this debate and to see what possible solutions to the existing dilemmas are available. In this article, we will attempt to map out the main players and arguments for the Czech reader, critically present and evaluate them.

Damage by Pests in Herbarium LJU
Authors: Bačič Tinka , Trčak Branka , Jogan Nejc
Published: August 2023

The article discusses the damage caused by herbarium pests in Herbarium LJU. The aim of the study was to determine the damage in the herbarium, to ﬁnd out, which herbarium-pests are present, and to investigate their food-preference by means of checking the extent of damage on a selection of plant families Alliaceae, Apiaceae, Araceae, Asteraceae, Brassicaceae, Chenopodiaceae, Cichoriaceae, Faba- ceae, Lamiaceae, Poaceae, Polypodiaceae, Ranunculaceae, Rosaceae and Scrophulariaceae. Since the Asteraceae and Cichoriaceae are known to be among the most attractive families for herbarium-pests, we examined them in detail. In the study about 7500 herbarium sheets were examined, which represents 5% of all the sheets inHerbarium LJU. In addition to the most frequent pest tobacco beetle (Lasioderma serricorne), we also found beetles Stegobium paniceum and Attagenuspiceus, booklice (Psocoptera), moulds and Pharaoh’s ants (cf. Monomorium pharaonis). Pest-damage was observed in 18 % of the examined herbarium sheets. The study conﬁrmed that the pests are prone to attack certain families over others: the greatest damage (about 25 % - 40 % of the damaged sheets)was observed in Apiaceae, Asteraceae s. lat., Brassicaceae, Fabaceae, Alliaceae, Araceae, Rosaceae and Chenopodiaceae, while the other investigated families ranked among less damaged (about less then 10 % of the damaged sheets). Among Asteraceae, tribus Cardueae proved to be the most attractive tribe for the pests.
A hydro-acoustics approach of accessing macrophyte biomass data
Authors: Exler Norbert , Janauer Georg
Published: August 2023

Hydro-acoustic methods are commonly used to estimate the abundance and distribution pattern of ﬁsh in aquatic environments, while studies on the assessment of the biomass of submerged macrophytes in the littoral zones are still rare. In the present study we provide ﬁrst results showing that indeed this method is a useful tool to estimate the aquatic plant stands in lakes. The aim of the recent presentation is to show an initial data evaluation by graphs describing hydro-acoustic signals at three distinct layers in a small shallow lake: the solid sediment, the ﬁne or muddy sediment, and the ‘plant canopy’ of submerse macrophytes. The most difﬁculties of data processing and assessment of biomass were for hydro-acoustic records close to the water surface where the echo-signal is interfered by reﬂectance. Methodological details and progress in evaluating hydro-acoustic records will be discussed.

Lilium martagon L. var. cattaniae Vis. (Liliaceae) is endemic plant of Dinaridi mountain. In this work we established protocol for fast in vitro propagation and multiplication of Lilium martagon var. cattaniae. The aim was to enable fast production of plant material as potential source of pharmaceutically valuable secondary metabolites. Seeds of L.martagon var. cattaniae were germinated on a Murashige and Skoog basal medium with a supplement of 0.15 mg/l gibberellic acid (GA3), and multiplication was performed on MS medium supplemented with 0.1 mg/l gibberellic acid (GA3), 0.2 mg/l indole-3-butyric acid (IBA) and 0.5 mg/l 6-ben- zylaminopurine (BAP). We used ultrasound assisted extraction to prepare extracts of leaves and bulbs of Lilium martagon var. cattaniae, which were evaluated for their genotoxic potential using Allium test and cytokinesis-block micronucleus test in human lymphocytes culture. There was statistically signiﬁcant difference between all used concentrations of lilium extracts and control on proliferation of cells of root tip of onion (Allium cepa). In cytokinesis-block micronucleus test no statistically signiﬁcant difference between frequencies of analyzed parameters in samples treated with tested concentrations of extracts and control was obtained.
Lack of introns in putative parasitism factor gene, expansin (expB2) from pale potato cyst nematode Globodera pallida
Authors: Gerič Stare Barbara , Širca Saša , Urek Gregor
Published: August 2023

Expansins are a group of plant cell wall loosening proteins. In animals, functional expansin (EXPB1) has been discovered in the golden potato cyst nematode Globodera rostochiensis. In plant-parasitic nematodes expansins act as the parasitism factors or effectors. Molecularvariability of another expansin (expB2) gene was eva- luated in the diverse populations of the G. rostochiensis. Comparison of the expB2 genestructure in the two potato cyst nematode species, G. rostochiensis and G. pallida, revealed lack of all four introns in expB2 gene of G. pallida species. Possible loss of introns in Gp-expB2 is discussed.

Influence of red deer (Cervus elaphus L.) grazing on yield reduction and changes in the chemical composition of grassland forage: experiences from an organic farm at Stari Breg in the Kočevje Region
Authors: Vidrih Matej , Laznik Žiga , Sinkovič Tomaž , Jakovac Strajn Breda , Tavčar Kalcher Gabrijela , Trdan Stanislav
Published: August 2023

In 2013 and 2014 the effect of red deer grazing (Cervus elaphus) on yield decrease and its changes in forage quality was investigated on the permanent grassland of an organic cattle farm at Stari Breg in the Kočevje region. We performed the standard method of yield loss determination (iron cages) in the period from June to October in three cuts. In the first year of research we determined a 56% yield loss (4.0 t/haof dry matter), and in the second year a 75% yield loss (5.0 t/ha of dry matter). In 2014 the content of crude proteins in the forage was always larger in an unprotected (control) treatment than in a protected treatment, and we annotate this to permanent vegetative sward regrowth due to severe and uncontrolled red deer grazing. On the contrary, the content of crude fiber was higher in the forage that was enclosed in cages (treatment protected). Due to large yield loss at all cuts we also observed a significantly smaller yield of crude proteins, metabolized energy, and NEL in the control treatment. We established that in the studied location that red deer were an important biotic factor that limited productivity on the permanent grassland. This is why it is necessary to find solutions in the future that enable the co-existence of humans (farmers) and wildlife.
Taxonomy, phytogeography and phytosociology of Laserpitium krapfii Crantz. in Slovenia
Authors: Bačič Tinka , Accetto Marko , Vreš Branko , Dakskobler Igor
Published: August 2023

The article discusses the occurrence, distribution and phytosociological affinity of Laserpitium krapfii in Slovenia. According to some literature sources (Tutin 1968, Fischer et al. 2008) and the distribution patterns, two subspecies of L. krapfii are be expected in Slovenia: L. krapfii subsp. krapfii and L. krapfii subsp. gaudinii. The revision of the Slovene herbarium material in LJU and LJS herbaria confirmed only the occurrence of its type subspecies. It has a Dinaric pattern of distribution (NW-SE) in the Alpine, Prealpine, Dinaric and Predinaric phytogeographical regions, with most of its known localities in the hills south of Ljubljana, in the Snežnik mountains, in the Kočevje region with the Kolpa Valley and in the Gorjanci mountains. Since the species mostly thrives in the mountain beech forests, it can be considered as a diagnostic (differential) species of the Illyrian alliance Aremonio-Fagion.
Cytological analysis of Fallopia japonica and Fallopia ×bohemica shoots during growth season

Published: August 2023

Fallopia japonica and Fallopia ×bohemica are two very invasive plant species in Europe and North America. Their main mode of spread is vegetative reproduction. In spring new shoots emerge from the overwintering rhizome, grow rapidly and develop broad leaves which shade undergrowth plants. We studied cell size and starch accumulation in three stem regions at five sampling times during one growth season to determine possible differences in growth dynamics of both Fallopia species. On average F. ×bohemica had somewhat larger cells than F. japonica but the differences were not significant, except in the internodes of the middle stem region with differentiating cells. Also, cell growth dynamics of both species was similar and the only difference was detectedat the 2nd sampling when cells of F. ×bohemica were more elongated. F. ×bohemica also accumulated starch earlier in the growth season and in younger tissues than F. japonica.

Response of macrophyte Berula erecta to low concentrations of NaCl in vitro
Authors: Mechora Špela , Ambrožič Dolinšek Jana
Published: August 2023

Macrophyte Berula erecta, grown in tissue culture, was exposed to various low concentrations of NaCl in the water (1–100 mg L-1). Added NaCl had a positive effect on plant’s growth and development. The number of shoots increased, as well as the length of the roots. The lowest concentration (1 mg L-1) increased photochemical efficiency of photosystem II (Fv/Fm) while the highest (100 mg L-1) slightly decreased it. Chlorophyll content was negatively affected by NaCl addition after 3 weeks. Carotenoid and anthocyanin levels were firstly raised and later lowered in NaCl treatment comparing to control. Overall, added NaCl had no negative effect on plants morphology, while decreased amount of pigments was observed.
