Rozšíření myšivky horské (Sicista betulina) v Pošumaví na základě rozboru potravy sov (Rodentia: Zapodidae)

Published: March 2024

Distribution of Sicista betulina in the Šumava Mts. (Bohemian Forest, SW Bohemia, Czech Republic) based on owl diet analysis (Rodentia: Zapodidae). The Šumava Mountains are one of the three areas of a relict occurrence of the northern birch mouse (Sicista betulina) in the Czech Republic. The present study summarises all records of this species obtained there by the analysis of diet of three species of owls, the Tengmalm’s owl (Aegolius funereus), to a lesser extent of the Ural owl (Strix uralensis) and tawny owl (Strix aluco). A total of 355 sample sets from 228 localities was processed, positive findings concern 57 localities where the northern birch mouse was found (322 individuals). The presence of the species was confirmed in an area of approximately 1,400 km2, which corresponds to 13 mapping fields of the KFME, four of which extend into the territories of Germany and Austria (field numbers 7047, 7148, 7249, 7350). More than a third of the localities (37.0%) and nearly two thirds of the individuals (62.4%) come from four mapping fields (7048, 7049, 7148, 7149) covering mainly a peaty alluvial plain of the upper stream of the Vltava river and its surroundings. Data obtained by observation or capturing of the northern birch mouse give a similar picture. Thus, this territory with the high proportion of relict vegetation can be considered as the core area of the current occurrence of the mouse in the Šumava Mts. The altitude range of the northern birch mouse records from owl pellets is 680–1160 m a. s. l. with a mean of 871.7 m a. s. l. Almost a third of the localities (32.0%) lie in the altitudinal range of 700–800 m a. s. l., and more than four fifths of the records (82.7%) fall within the range of 700–1000 m a. s. l. However, these are only indicative values that can be influenced by the size of the individual hunting territories of owls (especially in a landscape with a steep mountainous relief). Our results confirm the previously described zoogeographical profile of the northern birch mouse in the Šumava Mts., i.e., that its distribution is limited only to the south-eastern half of this mountain range and ends roughly in the Kvildské pláně region in the north-west. Records of the northern birch mouse on the Bavarian side of the mountain range are in full agreement with this. It can be assumed that the species occurrence in the whole Bohemian Forest is primarily shaped by its Holocene history. Furthermore, it has been confirmed that the analysis of the diet composition of the Tengmalm’s owl is an effective method of study of the geographical distribution of the northern birch mouse.
Threat assessment for dormice in Latvia – facts and assumptions (Rodentia: Gliridae)
Authors: Pilāts Valdis , Taube Laura , Pilāte Digna
Published: March 2024

In Latvia, dormice were one of the less studied mammal taxonomic groups until the 21st century, due to their elusive way of life. Historical threat assessments of dormouse species conducted in the 1970s and 1990s were constrained by a scarcity of observations, primarily relying on accidental encounters. In 2021, a comprehensive reassessment of the threat status of four dormouse species recorded in Latvia – Glis glis, Eliomys quercinus, Dryomys nitedula, and Muscardinus avellanarius – was initiated, by applying the methodological framework developed by the International Union for Conservation of Nature (IUCN). Here we evaluate the outcomes of these reassessments in the context of previous threat assessments at the national level as well as in the regional context. Historical and current species status in neighbouring countries, as well as necessary protective measures in Latvia were also considered.
Culture and traditions in vocal communication of cetaceans: a review (Cetartiodactyla: Cetacea)
Authors: Zvěřinová Adéla , Šimková Olga , Landová Eva
Published: March 2024

Vocal communication is the main mean of communication for cetaceans and some species developed vocal culture and traditions. They are maintained through both production and contextual learning, used to acquire two types of sounds: signature calls and songs. Signature calls are present only in species living in stable groups or fission-fusion society. They are used as an identification tool to maintain cohesion and contact with conspecifics. Songs are present in most baleen whales, but only humpback and bowhead whales change within and between seasons. They use vocal learning to conform to one type used by all individuals. Vocal learning is also employed during vocal development in ontogenesis, together with maturation. The existence of social groups in other species together with the lack of research suggest that traditions are more widespread among cetaceans than is currently known.

Post-loss speeding or post-win slowing? An empirical note on the interpretation of decision-making time as a function of previous outcome
Authors: Dyson Benjamin James
Published: March 2024

Differences in response time following previous losses relative to previous wins are robust observations in behavioural science, often attributed to an increased (or decreased) degree of cognitive control exerted after negative feedback, hence, post-loss slowing (or post-loss speeding). This presumes that the locus of this effect resides in the specific modulation of decision time following negative outcomes. Across two experiments, I demonstrate how the use of absolute rather than relative processing speeds, and the sensitivity of processing speeds in response to specific experimental manipulations (Experiment 1: win rate, Experiment 2: feedback), provide clarity as to the relative weighting of post-win and post-loss states in determining these behavioural effects. Both experiments show that the speeding or slowing of decision-time is largely due to the flexibility generated by post-win cognitive states. Given that post-loss speeding may actually represent post-win slowing, conclusions regarding the modulation of decision-making time as a function of previous outcomes need to be more carefully considered.

Parsing signals from noise is a general problem for signallers and recipients, and for researchers studying communicative systems. Substantial efforts have been invested in comparing how other species encode information and meaning, and how signalling is structured. However, research depends on identifying and discriminating signals that represent meaningful units of analysis. Early approaches to defining signal repertoires applied top-down approaches, classifying cases into predefined signal types. Recently, more labour-intensive methods have taken a bottom-up approach describing detailed features of each signal and clustering cases based on patterns of similarity in multi-dimensional feature-space that were previously undetectable. Nevertheless, it remains essential to assess whether the resulting repertoires are composed of relevant units from the perspective of the species using them, and redefining repertoires when additional data become available. In this paper we provide a framework that takes data from the largest set of wild chimpanzee (Pan troglodytes) gestures currently available, splitting gesture types at a fine scale based on modifying features of gesture expression using latent class analysis (a model-based cluster detection algorithm for categorical variables), and then determining whether this splitting process reduces uncertainty about the goal or community of the gesture. Our method allows different features of interest to be incorporated into the splitting process, providing substantial future flexibility across, for example, species, populations, and levels of signal granularity. Doing so, we provide a powerful tool allowing researchers interested in gestural communication to establish repertoires of relevant units for subsequent analyses within and between systems of communication.
Statistical indices of masculinity-femininity: A theoretical and practical framework
Authors: Del Giudice Marco
Published: March 2024

Statistical indices of masculinity-femininity (M-F) summarize multivariate profiles of sex-related traits as positions on a single continuum of individual differences, from masculine to feminine. This approach goes back to the early days of sex differences research; however, a systematic discussion of alternative M-F indices (including their meaning, their mutual relations, and their psychometric properties) has been lacking. In this paper I present an integrative theoretical framework for the statistical assessment of masculinity-femininity, and provide practical guidance to researchers who wish to apply these methods to their data. I describe four basic types of M-F indices: sex-directionality, sex-typicality, sex-probability, and sex-centrality. I examine their similarities and differences in detail, and consider alternative ways of computing them. Next, I discuss the impact of measurement error on the validity of these indices, and outline some potential remedies. Finally, I illustrate the concepts presented in the paper with a selection of real-world datasets on body morphology, brain morphology, and personality. An R function is available to easily calculate multiple M-F indices from empirical data (with or without correction for measurement error) and draw summary plots of their individual and joint distributions.

This work focusses on the potential application of waste cooking oil (WCO) as alternative to diesel as it is abundantly, locally available. The oil is subsequently converted into its biodiesel called waste cooking biodiesel (WCOBD). GCMS studies of the waste cooking oil and its biodiesel is carried out to determine the fatty acid composition. Further WCOBD is blended with diesel to produce its WCOBD B20 blend. The physio-chemical properties of the WCO, WCOBD, WCOBD B20 and their nano-biodiesel blends were determined and were compared with diesel. These properties of WCOBD B20 are in good agreement with diesel. This B20 blend can successfully provide 20% substitute to fossil diesel and save foreign exchange besides providing energy security to India. The fuel properties of the WCOBD B20 blends are further modified by adding carbon derived nanoparticles of reduced graphene oxide (RGO) to prepare nano-biodiesel blends. The percentage of RGO nanoparticles were varied from 20% to 100 % by volume insteps of 20% using suitable SDS surfactants. The stability of these nano-biodiesel blends is determined by using zeta potential method. The stability of decreased with increase in the nano-particle dosage in base biodiesel blends. Accordingly, the blends with dosage beyond 80% showed lower stability in terms of lower zeta potential values. The nano-biodiesel blends showed improvement in calorific value and self-ignition temperature compared to the B20 biodiesel blend.

Fertilizer spreaders play a crucial role in evenly distributing granule fertilizer across palm plantations. However, in specific areas where growth conditions are unsuitable, fertilizer application becomes unnecessary. Therefore, this study aims to improve granule fertilizer distribution efficiency through enhanced fertilizer blade design. Using Finite Element (FE) simulation, the stress deformation and deflection of the existing spreader blade were evaluated. Meanwhile, Computational Fluid Dynamics (CFD) simulation was used to investigate the influence of spreader design on fertilizer projection speed and direction in the case of open and closed side discharge. The study revealed that the applied forces increased both the critical stress deformation and deflection. To ensure the fertilizer spreads properly over the desired area, the initial velocity had to be increased proportionally with an increase in the angle of direction. These findings contributed to a deeper understanding of the relationship between fertilizer projection velocity, spreader blade strength, and flow behaviour, enabling the reduction of waste in granule fertilizer, while enhancing the operational efficiency and reliability of fertilizer spreader.

The purpose of this study is to investigate the evaporation characteristics of different types of fuels by applying the hot surface deposition test (HSDT). Generally, HSDT method is a simplified method to simulate fuel deposition in diesel engines. In this study, diesel fuel (DF) and palm oil biodiesel with different blend ratios (B10-B50) were used to evaluate the fuel droplet evaporation behavior on a heated aluminum alloy plate surface. Single fuel droplet was impinged on the heated plate at various surface temperatures (Ts). Important data from the evaporation characteristics was the maximum evaporation point (MEP), which is the temperature point where a droplet evaporates in the shortest lifetime (tlife). MEP is referred to identify the surface temperature range in which fewer deposits will be produced by the test fuel. Furthermore, MEP is also used to determine the appropriate droplet interval to create wet and dry conditions in the fuel deposition test. The obtained MEP was 360°C (DF), 365°C (B10, B50), 375°C (B20, B40), and 385°C (B30).
Flow Reversal of Unsteady Oscillatory Flow in Combined Convection Fully Developed Vertical Channel
Authors: Nur Asiah
Published: March 2024

Numerical simulations of flow and heat transfer in an unsteady oscillatory fully developed combined convection are conducted. The temperature on the right wall varies with sinusoidal rhythm over time within a locked mean temperature, whereas the temperature on the left wall remains constant. Both walls are also considered to be stationary. A numerical solution for the momentum and energy equations obtained using the Runga- Kutta method is used to analyze the effect of periodic oscillation on the velocity and temperature configurations, as well as the progression of heat generations. The combined convection process of heat transfer and its flow pattern in a vertical channel is important in many applications, including environmental, industrial, and engineering. This study is prompted by a problem with the heat transfer process, which is difficult, expensive, and time-consuming. The purpose of this study is to develop a mathematical model, find a numerical solution, and conduct parametric studies on the double-diffusive fully developed vertical channel with unsteady oscillatory flow, as well as to investigate the effect of various parameters on the velocity and temperature profiles. The effect of different dimensional parameters is tested and the flow reversal phenomenon is discussed. The dimensional equations are transformed into non-dimensional equations using the similarity technique. Then, the built-in program dsolve in Maple is used to numerically solve the boundary value problem (BVP). A validation study is conducted on a previously reported problem to confirm the validity of the present calculation. The flow and temperature numerical findings are represented visually. It is found that a large development of flow is caused by the plate temperature oscillation with high amplitude, therefore, the nature of the flow differs from the non-oscillating case.

Due to global warming, population growth, and urbanisation, demands for space cooling in buildings have significantly increased. Mechanical vapour compression cooling technology is relatively mature, well-understood and most commonly used globally. However, they suffer from high energy consumption and adverse environmental impact due to the refrigerants used. As ambient temperature and humidity have significant effects on the performance of vapour compression systems, this paper experimentally and numerically investigates their impact on the performance of vapour compression air conditioning system in terms of power consumption and cooling capacity. It was concluded that at ambient humidity of 55%, as the ambient temperature increases from 22 °C to 40 °C, the compressor temperature has increased from 46 °C to 59 °C which increased its power consumption from 751.2 to 935.52 Watts, giving an increase of 10.24 Watts for every one degree of ambient temperature increase. Also, as ambient humidity in-creased from 32% to 88%, the power consumption increased from 739.2 Watts to 853.2 Watts, an increase of 114 Watts. A validated CFD (Computational Fluid Dynamics) model was developed and predicted a loss in the enthalpy change from 11.7kJ/kg.d.a to 3.6kJ/kg.d.a. due to ambient temperature increasing from 22 °C to 40 °C and a loss of enthalpy change from 12.857kJ/kg.d.a to 5.524kJ/kg.d.a. due to increasing the ambient air humidity from 32% to 88%. This work high-lighted the impacts of ambient conditions on the performance of vapour compression cooling system in terms of increased power consumption and loss of cooling capacity.

Rapid industrial development with intensive operations increases exhaust emissions that are polluting the environment and human health. Efforts to overcome the problem are urgent to be realized, one of which is by using a particle separator such as a cyclone separator. Along with that, the design of a cyclone separator with the best performance is very important. Therefore, it is necessary to innovate and analyze the design of the cyclone separator by varying the cone geometry of the cyclone. This study aimed to determine the best square cyclone separator among square cyclone separators with various cone geometries, including single cone, dual inverse cone 1, and dual inverse cone 2. It was conducted by Computational Fluid Dynamics (CFD) simulation and experiments and then continued by comparing pre-determined aspects comprising pressure drop, collection efficiency, static pressure contours, tangential velocity contours in the cyclone body, tangential velocity vectors in the cone geometry, and tangential velocity vectors at the cyclone inlet. The single cone is the best among all cone variations since it fulfils more aspects better than the dual inverse cones, namely: dominantly lowest pressure drop of 188.5 Pa, static pressure contour of 10.42 Pa, tangential velocity contour of 3.06 m/s, flow direction of the tangential velocity vector in the cyclone geometry was at the centre of the bin, and flow direction of the tangential velocity vector at the cyclone inlet was parallel.

Published: March 2024

Salah satu kabupaten di Provinsi Sulawesi Selatan yang memiliki wilayah pesisir adalah Kabupaten Jeneponto. Bagi masyarakat Jeneponto, wilayah pesisir ini memiliki arti penting tidak hanya karena kekayaan keanekaragamannya namun juga karena aktivitas ekonominya, termasuk perikanan, budidaya rumput laut, dan rekreasi. Namun saat ini erosi pantai di Kabupaten Jeneponto sudah sangat parah. Sistem alam akan memburuk jika pencegahan abrasi air laut tidak dilakukan, sehingga mengubah garis pantai dalam prosesnya. Tujuan dari penelitian ini adalah untuk mengevaluasi rancangan bangunan keselamatan pantai yang akan dimanfaatkan di Pantai Tamarunang dan mencari alternatif penanggulangan yang akan dibangun. Proses analisis melibatkan pemilihan bangunan pengaman pantai pengganti dan perhitungan desainnya.

Tembok laut atau penyangga beton heksagonal merupakan perlakuan dengan titik terbanyak menurut matriks yang digunakan dalam penelitian ini untuk memilih alternatif konstruksi keselamatan pantai. Namun dalam memilih perawatan pantai, perlu kembali mempertimbangkan berbagai kondisi di sepanjang pantai Tamarunang. Dari segi kesediaan masyarakat, selama tindakan pengamanan tidak menghalangi arus perahu yang membawa nelayan dan petani rumput laut, maka masyarakat boleh saja diberikan perlindungan di sepanjang pantai Tamarunang. Berdasarkan hasil penelitian, dapat diambil kesimpulan sebagai berikut: 1. Ketinggian tembok laut adalah 2,44 meter; 2. Batu yang digunakan untuk tembok laut memiliki berat 27 kg; dan 3. Diameter batu tersebut adalah 27 cm.
