Influence of the Ports of the Northern Sea Route on the Formation of Focal Zones for the Development of the Eastern Arctic
Authors:   Economic Research Institute of Far Eastern Branch of the Russian Academy of Sciences, Leonov S.N.
Published: April 2021

The authors consider propulsive potential of the ports of the eastern section of the Northern Sea Route (NSR) and indicate the influence of the NSR on increasing the efficiency of the key zones formation for the development of the Far Eastern Arctic. They base the work methodology on the theory of cumulative growth, in which the ideas of the “growth poles” formation occupy a decisive position. The authors use the grouping methods, logical and comparative analysis. The Rosstat data serves as an information base of the study. It is shown that the state’s activity on the development of the NSR stimulates the development of the North Yakutsk and Chukotka support zones, enhancing the transport and raw materials specialization of the Eastern Arctic as a whole. At the same time, the authorities proceed from the assumption that the development of ports should reduce the costs of trade, increase employment, and have a multiplier effect both on the port system itself and on the sectors of the region interacting with it. The paper substantiates that in the Far Eastern Arctic, the traditional view of ports as the most important infrastructure assets, which are the business and economic center of territorial development, is insufficient for the recognition of transport infrastructure as a propulsion industry. The propulsive effect of the port economy is low and is mainly of an induced nature, when capacities for processing products are created in the port areas, or when the transport infrastructure stimulates the emergence of transport-intensive extractive industries, which is provided in the western part of the NSR. For the development of the North Yakutsk and Chukotka Arctic support zones, the transport infrastructure will be a backbone project that “connects” these regions in an economically sustainable spatial formation — the Far Eastern Arctic. Transport is a necessary but insufficient condition for the emergence and accelerated development of local “growth poles” in the Eastern Arctic.

Authors: Rafil Rafil Arizona
Published: April 2021

Batteries are one of the world's favorite sources of energy because of their ease and practicality of use. In a conventional battery, there are heavy metals such as mercury, lead, cadmium, and nickel. All these metals are B3 waste which is very dangerous for the environment and the human body if it is not recycled properly. Efforts that can be made to overcome the problem of B3 waste above are by researching and utilizing the waste of banana peel (Musa Balbisiana) to produce direct electrical energy (DC). With the aim of the community getting an environmentally friendly source of electrical energy, easy to recycle and worrying about the magnitude of the danger because the impact of heavy metals can be reduced. The purpose of this study is to determine the voltage (voltage) produced and the durability of the bio-battery made. The method used is to make a bio-battery paste from banana peels instead of the paste on conventional batteries. The results obtained from this study are the banana peel waste paste can conduct electricity. Produces a voltage of 1.24 volts and the bio-battery made from banana peel can last for 16 hours.
Türkiye ve Yeşil Ekonomi: Mevcut Durum ve Öneriler
Authors: Yıldız Furkan
Published: April 2021

Sanayi Devrimi ile birlikte hız kazanan kitlesel üretim “her şeye rağmen üretim” anlayışının hâkim olduğu bir ekonomik yarışı beraberinde getirmiştir. Böylelikle ülkeler bu yarışta geri kalmamak adına üretimlerini en üst seviyeye çıkarmışlardır. Ancak bu durum beraberinde savaş, küresel ısınma, iklim değişikliği gibi birçok toplumsal ya da çevresel problemleri beraberinde getirmiştir. Yaşanan bu gelişmeler günün sonunda neoliberal politikaların ciddi bir biçimde sorgulanmasına ve bu hâkim paradigmaya alternatif bakış açıları geliştirilmesine neden olmuştur. Mevcut iktisadi sisteme alternatif olarak öne sürülen yaklaşımlardan biri de yeşil ekonomidir. Özünde ekonomi, çevre ve toplumun sürdürülebilirliği ilkesini taşıyan yeşil ekonomi özellikle 1980’ler itibariyle çevresel kirliliğin artması ile giderek önem kazanan bir kavram olarak karşımıza çıkmaktadır. Bu cihette ülkeler hem kendi inisiyatifleriyle politikalarına yeşil ekonomik anlayışı adapte etmeye hem de uluslararası toplumca atılan adımlara taraf olmaya başlamışlardır. Bu politika notunda Türkiye’nin yeşil ekonomi bağlamında mevcut durumu incelenmiş ve birtakım politika önerilerinde bulunulmuştur. Türkiye’nin mevcut performansı değerlendirildiğinde elde ettiği bazı kazanımlar olmasına rağmen yeşil ekonomik sistemi toplumsal ya da kamusal alanda zihinlere henüz yeterince yerleştiremediği anlaşılmaktadır
Comparative Investigation of Non-halogenated Imidazolium and Phosphonium-based Surface-Active Ionic Liquids as Electrolyte for Supercapacitors
Authors: Jain Preeti , Antzutkin Oleg N.
Published: April 2021

We report a comparative analysis of non-halogenated surface-active ionic liquids (SAILs), which consists of the surface-active anion, 2-ethylhexyl sulfate, and the phosphonium, and imidazolium cations i.e., tetrabutylphosphonium ([P4444]+), trihexyl(tetradecyl)phosphonium ([P66614]+), and 1-methyl-3-hexylimidazolium ([C6C1IM]+). We explored the thermal and electrochemical properties, i.e., degradation, melting and crystallization temperatures, and ionic conductivity of this new class of IL. These SAILs were tested as an electrolyte in a multi-walled carbon nanotubes (MWCNTs)-based supercapacitor at various temperatures from 253 to 373 K. The electrochemical performance of different SAILs by varying the cationic core as a function of temperature were compared, in the same MWCNT-based supercapacitor. We found that the supercapacitor cell with [C6C1IM][EHS] shown high specific capacitance (Celec in F g-1), a high energy density (E in Wh kg-1), and a high power density (P in kW kg-1) when compared to those for the other SAILs i.e. [P4444][EHS], [P66614][EHS], and [N8888][EHS] at all temperatures. The supercapacitor with an MWCNT-based electrode and [C6C1IM][EHS], [P4444][EHS], and [P66614][EHS] as an electrolyte showed a specific capacitance of 148, 90, and 47 F g-1 (at the scan rate of 2 mV s-1) with an energy density of 82, 50, and 26 Wh kg-1 (at 2 mV s-1) respectively, at 298 K. The temperature effect can be seen by the three to four-fold increase in the specific capacitance of the cell and the energy density values, i.e., 290, 198, and 114 F g-1 (at 2 mV s-1) and 161, 110, and 63 Wh kg-1 (at 2 mV s-1), respectively, at 373 K. This study reveals that these new SAILs specifically [C6C1IM][EHS] and [P4444][EHS] can potentially be used as electrolytes in the wide range of temperature. The solution resistance (Rs), charge transfer resistance (Rct), and equivalent series resistance (ESR) also decreased with an increase in temperature for all SAILs as electrolytes. These new SAILs can explicitly be used for high-temperature (wide range of temperature) electrochemical applications, such as efficient supercapacitors for high energy storage due to enhanced specific capacitance, energy, and power density at elevated temperatures.
Developing Machine Learning Models for Ionic Conductivity of Imidazolium-Based Ionic Liquids
Authors: Dhakal Pratik , Shah Jindal
Published: April 2021

In this work, we have developed machine learning models based on support vector machine (SVM) and artificial neural network (ANN) to correlate ionic conductivity of imidazolium-based ionic liquids. The data, collected from the NIST ILThermo Database, spans six orders of magnitude and ranges from 275-475 K. Both models were found to exhibit very good performance. The ANN-model was then used to predict ionic conductivity for all the possible combinations of cations and anions contained in the original dataset, which led to the identification of an ionic liquid with 30% higher ionic conductivity than the highest conductivity reported in the database at 298 K. The model was further employed to predict ionic conductivity of binary ionic liquid mixtures. A large number of ionic liquid mixtures were found to possess non-ideal behavior in that an intermediate mole fraction for such ionic liquid mixtures resulted in either a maximum or minimum in the ionic conductivity.

This report demonstrates how scanning X-ray fluorescence microscopy (SXFM) and nanoscale X-ray absorption near-edge structure (nano-XANES) can spatially and chemically identify intracellular iron species at the single-cell level, creating an opportunity to examine the role of iron storage in magnetite biomineralization. Fe K-edge nano-XANES measurements of Magnetospirillum gryphiswaldense in varied iron media conditions and iron storage capacity revealed intracellular iron heterogeneities through a distinction between formed magnetosomes and intracellular iron material. This work highlights the potential of nano-XANES in providing an experimental advantage in the multidisciplinary field of biomineralization.
Ni-Catalyzed Aryl Sulfide Synthesis through an Aryl Exchange Reaction
Authors: Isshiki Ryota , Kurosawa Miki B. , Muto Kei , Yamaguchi Junichiro
Published: April 2021

A Ni-catalyzed aryl sulfide synthesis through an aryl exchange reaction between aryl sulfides and a variety of aryl electrophiles was developed. By using 2-pyridyl sulfide as a sulfide donor, this reaction achieved the synthesis of aryl sulfides without using odorous and toxic thiols. The use of a Ni/dcypt catalyst capable of cleaving and forming aryl–S bonds was important for the aryl exchange reaction between 2-pyridyl sulfides and aryl electrophiles, which include aromatic esters, arenol derivatives, and aryl halides. Mechanistic studies revealed that Ni/dcypt can simultaneously undergo oxidative additions of aryl sulfides and aromatic esters, followed by ligand exchange between the generated aryl–Ni–SR and aryl–Ni–OAr species to furnish aryl exchanged compounds.

Authors: Gu Fan , Li Yuanhao , Jiang Tao , Su Jianhua , Ma Xiang , Tian He
Published: April 2021

Photoluminescence materials play an inseparable role in the application of polymer systems. However, intrinsic polymer systems have rarely been intuitively interpreted based on photoluminescence regulation. A novel photoluminescence mechanism called vibration-induced emission (VIE) has recently drawn great attention due to its multicolor fluorescence from a single molecular entity. Based on the unique fluorescent properties of VIE molecules, we doped 9,14-diphenyl-9,14-dihydrodibenzo[a,c]-phenazine (DPAC) and its derivative DPAC-CN in two stretchable polymers, poly(ε-caprolactone) and ethylene vinyl acetate (EVA) copolymer, to explore the important relationship between luminophores and polymer systems. This research focused on the multicolor photoluminescence of the obtained blend films that resulted from stretching exertions and temperature responses. The successive conformational alterations of VIE molecules endowed continuous photoluminescent changes. Meanwhile, the multicolor variations also provided specific visual evidence regarding the amplified tensile stresses and microstructural changes in the polymer. This demonstration will therefore provide advantageous insights into the development of functional optical materials.
GREETING AND LEAVE TAKING AMONG NATIVE SASAK IN LOMBOK
Authors: Atika Istikhorini
Published: April 2021

Greetings and leave-takings are conversational routine used to maintain person’s relationship in society. However, each culture may have different ways of expressing them. In English, the common greetings and leave-takings pattern used are time-free and time-bound greeting expressed by good afternoon, good evening, good night, nice to meet you and so forth. These are not found in Sasak, so they may cause problem for native Sasak speaker to understand another culture greetings and leave takings; conversely for non-native Sasak speaker who intends to learn them as well. The aim of this study is to find out the forms of greeting and leave taking that appear in Sasak. This study uses ethnography design. To collect the data, observation sheet is utilized. Then, using Haliday’s theory of time-free and time-bound greeting, the data is analyzed by comparing and contrasting greeting and leave-taking patterns used in English and Sasak. The result of the study indicates that Sasak types of greeting and leave taking consist of time-free and time-bound greeting. However, these forms are not exactly the same with common English greeting and leave-taking, they tend to be more phatic utterance (speech act which function to show solidarity and empathy). Therefore, the English curriculum linked with greeting and leave-taking material needs to be associated with Sasak greeting and leave-taking forms in order to create students’ better understanding.

Authors:   Universiti Pendidikan Sultan Idris, Malaysia, Md Nadzalan Ali
Published: April 2021

As a way to enhance performance in sports, apart from in-field or in court training, athletes are recommended to adopt resistance training into their training routine. As an exercise that needs the performer to split their legs, lunge is suggested to be included as an exercise in a training session. Various researches had been conducted on lunge and several findings showed different methods or protocols of lunge affect the kinematics, kinetics muscle activation and fascicle behaviour response during the exercise. Although not much study conducted on the chronic adaptations, the existing studies suggested that performers should well plan the training protocols as this will cause different training adaptations.

Managing Manufacturing Complexity Drivers on Performance – An Initial Study
Authors:   Universiti Teknikal Malaysia Melaka, Malaysia
Published: April 2021

Manufacturing systems, in pursuit of cost, time and flexibility optimisation are becoming more and more complex, exhibiting a dynamic and nonlinear behaviour. Unpredictability is a distinct characteristic of such behaviour and effects production planning significantly. Complexity continues to be a challenge in manufacturing systems, resulting in ever-inflating costs, operational issues and increased lead times to product realisation. This challenge must be met with appropriate decision-making by manufacturing companies to secure competitive advantage without compromising sustainability. Assessing complexity realises the reduction and management of complexity sources which contribute to lowering associated engineering costs and time, improves productivity and increases profitability. Therefore, this study was undertaken to investigate the priority level and current achievement of manufacturing performance in Malaysia’s manufacturing industry and the complexity drivers on manufacturing productivity performance. The results showed that Malaysia’s manufacturing industry prioritised product quality and they managed achieved a good on-time delivery performance. However, for other manufacturing performance, there was a difference where the current achievement of manufacturing performances in Malaysia’s manufacturing industry is slightly lower than the priority given to them. The strong correlation of significant value for priority status was observed between efficient production levelling (finished goods) and finish product management while the strong correlation of significant value for current achievement was minimised the number of workstation and factory transportation system. This indicates that complexity drivers have an impact towards manufacturing performance. Consequently, it is necessary to identify complexity drivers to achieve well manufacturing performance.
Effect of Alumina and Halloysite clay on Electrical tree growth in Silicone Rubber Nanocomposite
Authors:   Universiti Sains Malaysia, Malaysia
Published: April 2021

Nowadays Silicone Rubber (SiR) is recommended in high voltage cable accessories fabrication as it offers excellent electrical and mechanical properties. Electrical tree is one of the phenomenon which contributes to the main factor of SiR insulation breakdown. Recently, a new approach has been applied in order to enhance the insulation strength properties by introducing nano filler in undoped material. Thus, this paper presents the influence of nano-alumina and halloysite nanoclay on electrical tree growth in SiR at 0, 1 vol%, 2 vol% and 3 vol% concentration. The electrical tree growth was investigated at 8kVrms after tree inception voltage (TIV) within 30 minutes under room temperature. The results show reductions of electrical tree growth speed and accumulate damage (%) up to 2 vol% nano-alumina and up to 3 vol% halloysite nanoclay. Nevertheless the presence of 3 vol% nano-alumina in SiR leads to the faster electrical tree growth rate and the worst accumulate damage within 1 minute of electrical tree growth process.

Published: April 2021

Urbanization is making urban communities grow and increase in density. As this occurs, nature is expelled from urban areas and use of solid, slate and metal surfaces; carbon discharges increase the Urban Heat Island Effect. Rooftops are the spots that give an individual a chance to fantasize and allow them an imaginative standpoint towards their environment. What better place could there be for a garden or far and away superior, a vegetable garden? Rooftops are underutilized whereas it has a great potential. This paper is the study to understand the scope of development and perception of rooftop farming in residences in Bangalore. Two distinct surveys have been conducted to know the citizen's perception of the rooftop farming: one being a practitioner survey and the other is the non-practitioner survey. Rooftop farming has a wide applicability in zones with moderate climate and hence could be incorporated in the city very efficiently. To conclude, a few guidelines have been recommended to enhance rooftop cultivating practice and urge more individuals to rehearse rooftop farming for the better change of urban life.

SHARP POWER. THE EFFORT OF WESTERN AUTHORS TO DIVIDE SOFT POWER ON “OUR” AND “THEIRS”
Authors:   Russian Academy of Sciences Institute of World Economy and International Relations, Makhmud Anastasia Kh.
Published: April 2021

The article is dedicated to the analysis of the concept of sharp power, its nature, basic characteristics and tools. Sharp power was introduced by American scientists Ch. Walker and D. Ludwig at the end of 2017 as an alternative version of soft power inherent only in totalitarian or authoritarian regimes. American researchers claim that sharp power has a set of tools such as data falsification, cyber-attacks, propaganda, manipulation of news streams, etc., and it’s aim is to undermine and discredit on Western-style democracies and democratic values in general. The author puts in doubt the statements of Western scholars that sharp power is inherent exclusively to authoritarian powers, to which they include Russia, China, Iran and several other countries. Moreover, the heuristic significance of the concept of sharp power is called into question. Also, based on the analytical work done, the author of the article offers her own version of the translation of the term sharp power into Russian language. In the conclusion, she offers a critical assessment of the concept, rather as an ideological phenomenon aimed at forming favorable attitudes to its ideologues in the international foreign policy discourse, than as a scientific concept, which is synonymous with soft power and smart power
RELIGIOUS ACTIVITY OF ALI AKBAR HASHEMI RAFSANJANI
Authors:   Moscow State Linguistic University, Koklikov Vladimir O.
Published: April 2021

The paper analyzes the political and religious activities of Ali Akbar Hashemi Rafsanjani, one of the most famous politicians of modern Iran. His political and religious activities from youth to the end of his life are subject of the study. In particular, three periods of hislife are of interest here: his acquaintance with Ayatollah Khomeini and studying, religious activity before the Islamic revolution, and religious activity after the Islamic revolution. It is clear that Rafsanjani paid much attention to the study of the Quran and Islamic law, and after the Islamic revolution, he sought to promote religious ideas and Islamic legal regulations among Iranians. At the same time, after the revolution, Rafsanjani became very actively involved in the political life of Iran, occupying key positions in the main government bodies, including the presidency, as a result of what his own religious activity decreased significantly, although he nonetheless sought to combine politics and religion. The paper states that Rafsanjani took a moderate and pragmatic political position and changed his views depending on the circumstances in which the country found itself.

Authors: Kiebzak Wojciech
Published: April 2021

Introduction:
In the first year of life, the spine is very susceptible to various types of overload. During this period, it is extremely important to ensure optimal conditions for the physiological formation of curvature of the spine.

Aim:
The aim of the work is to present optimal ways of carrying infants, recommended by the authors.

Material and methods:
Using the keywords: ‘carrying children,’ ‘stacking babies,’ ‘moving babies,’ ‘carrying an infant,’ ‘stacking infants,’ ‘moving infants‘ the following databases were searched: ScienceDirect, Web of Science, PubMed, Scopus and ClinicalKey. Works published after 1990 were searched. The presented text describes the authors’ own experience gained throughout over 30 years of clinical work.

Results and discussion:
In the first year of life, manner of carrying a child should be adapted to the stage of its psychomotor development. During the first 4 months of life, the baby’s spine needs full support. Between 4 and 8 months of age, it is acceptable to carry the child vertically with relief from the spine. In the period when the child acquires ability to independently assume a sitting position and is able to control positioning of the torso in space, his body weight may rest on the tubers ischiale.

Dieng volcanic highland, where located in Wonosobo and Banjarnegara regencies, has a unique frost phenomenon that usually occurs in the dry season (July, August, and September). This phenomenon may attract tourism, but it has caused losses to farmers due to crop damage. Information regarding frost prediction is needed in order to minimize the negative impact of this extreme event. This study evaluates the potential use of the Subseasonal to Seasonal (S2S) forecast dataset for frost prediction, with a focus on two areas where frost usually occurs, i.e. the Arjuna Temple and Sikunir Hill. Daily minimum air temperature data used to predict frost events was from the outputs of the ECMWF model, which is one of the models contributed in the Subseasonal to Seasonal prediction project (S2S). The minimum air temperature observation data from the Banjarnegara station was used in conjunction with the Digital Elevation Model Nasional (DEMNAS) data to generate spatial data based on the lapse rate function. This spatial data was used as a reference to downscale the ECMWF S2S data using the bias correction approach. The results of this study indicated that the bias-corrected data of the ECMWF S2S forecast was able to show the spatial pattern of minimum air temperature from observations, especially during frost events. The S2S prediction represented by the bias-corrected ECMWF model has the potential for providing early warning of frost events in Dieng, with a lead time of more than one month before the event.

The article summarizes the results of 1990-2012 research conducted during the stationary experiment on leached heavy loam chernozem in the Republic of Mordovia. The objects of the study are two crop rotations (grain-grass-fallow and grain-grass crop rotations) where alfalfa of the VEGA 87 variety was used as a bean component, smooth brome (Bromus inermis) Penza 1 was used as a grain component. It has been established that mineral fertilizers in grain-grass-fallow crop rotations with legumes increased productivity by 0.34-0.55, with cereals – by 0.31-0.73 tons of feed units/ha. That provided to get additional income from 1.19 to 1.40 and 1.09 to 1.47 rub/rub, respectively. Recommended doses of mineral fertilizers against soil liming by 0.5 hydrolytic acidity (h.a,) were N22-39P42K52, for grain-grass-fallow crop rotation with alfalfa and N27-71P42K52. with smooth brome. In the grain-grass crop rotation with legume and cereal components the payback of 1 kg active ingredient (a.i.) of complete mineral fertilizer was 6.13 and 6.17 kg feed units, additional income was 2.00 and 1.99 rub/rub, the productivity increased by 0.86-1.08 and 0.84-1.22 tons of feed units/ha, respectively. The payback of 1 kg of a. i. nitrogen as part of a complete mineral fertilizer in this crop rotation averaged 13.04 kg feed units versus 11.5 kg in legumes. Recommended doses of mineral fertilizers were N26-87P46K65 against the background of liming of the soil by 0.5-1.0 h. a. In crop rotation with smooth brome phosphorus-potash fertilizers should not be applied due to the low additional income (0.97-1.07 rub/rub).

The results of the research were obtained in 2019-2020 on sod-podzolic middle-loam soil in the conditions of EuroNorth-East of the Russian Federation. There were studied 18 variants of increasing doses of mineral fertilizers in the range from 30 to 150 kg of active ingredient per hectare. Under the conditions of 2019 growing season, nitrogen fertilizers influenced the value of yield of Novichok barley variety to a greater extent (Y = 0.67 - 0. 11x2 + 1.33x, R2 = 0.92), in 2020 - phosphorus fertilizers (Y = 1.48 - 0.02x2 + 0.48x, R2 = 0.99). On average, over 2 years of research, the yield in the control variant without the use of fertilizers was 0.87 t/ha. Yield increase of barley grains because of enlarged fertilizer doses ranged from 1.38 to 3.90 t/ha. The payback of 1 kg of active ingredient of fertilizers with increase of barley yield decreased due to enlarged doses: from 15.3 (N30P30K30) to 8.3 kg (N150P150K150). On average for two years of the research the increasing doses and ratios of mineral fertilizers had no significant effect on technological properties of spring barley seeds. The content of crude protein in grain grew with increase in fertilizer doses (r = 0.55). To obtain grain of the 2nd class of quality it is necessary to apply not less than 90 kg of active ingredient/hectare of ammonium nitrate. According to the content of crude cellulose, the 1st class of grain quality has been obtained, and this indicator did not depend on the application of fertilizers. High profitability of cultivation of the Novichok spring barley variety (from 54.2 to 59.1 %) has been recorded by application of mineral fertilizers in doses N60P60N120, N60P60K60 and N120P120K120.
Age-related changes of the histological structure in the limb bones of the domestic fowl

To assess the possibility of using the bird bone tissue as a recording structure, the histomorphological parameters of the bone tissue of laying hens of the lohman brown cross from the Kirov region (9 females and 1 male) aged from 1 month to 7.5 years were investigated. The comparison of the cross-sections of the humerus and femur, the phalanx of the toe and tibiotarsus of a 6-year-old individual revealed that tibiotarsus is the least susceptible to resorption. For further research in 7 individuals, this bone was divided into 3 sections (T1, T2 and T3), for each of which the description and measurement of the microstructure of the cross sections was carried out. It was revealed that the process of resorption of the periosteum begins at 2.5 years of age with the appearance of primary osteons. At the age of 3.5 years and later they penetrate into all layers of the periosteum, locating in chains between the lines of arrested growth. At 4.5 years of age, secondary osteons appear in the place of the primary ones, and areas of resorption are formed at the intersection of the Haversian and Volkmann canals. At the age of 5.5 years the medullary bone disappears from the bone cavity, rounded cavities filled with centripetal deposition of new bone tissue at the edges appear within the resorption sites. At the age of 6-7 years, bone tissue degeneration occurs, when the small cavities enlarge and merge into large resorption cavities, up to the complete resorption of the mesost. In the distal part of tibiotarsus (T3), a prolonged apposition of the layers of the periosteum and the latest resorption were recorded. The increase of the thickness of the periosteum and a decrease in the density of the osteon population was revealed by the morphometry of cross sections of the center of diaphysis. The sites of tibiotarsus where the age of females corresponds to the lines of growth layer of the periosteum were determined. The sites with additional lines of the arrested growth were demarcated. It was concluded that the periosteal layer of the domestic fowl tibiotarsus in the distal and proximal sites are suitable as a recording structure.

Drug developers worldwide assess compound safety and efficacy using measures that include mouse core temperature and locomotor activity. Subtle differences in animal housing conditions between institutions can alter these values, impacting scientific rigor and reproducibility. In these
studies, adult male NIH Swiss mice were surgically implanted with radiotelemetry probes that simultaneously monitored core temperature and locomotor activity across various housing conditions. In the first study, ambient temperature was varied between 20 °C and 28°C in groups of singly
housed mice. Additional studies held the mice at a constant ambient temperature and examined the effects of cage density (housing animals singly or in groups of 3 or 6), bedding change and provision of nesting material, and the availability of a running wheel on core temperature and locomotor
activity. Mice overwhelmingly maintained species-typical core temperatures across all ambient temperatures, across all housing conditions, when bedding was fresh or old, and with or without the provision of cotton squares as nesting material. However, engaging in wheel running and the combination
of fresh bedding and cotton squares transiently increased core temperatures beyond the species-typical range. Similarly, the circadian distribution of locomotor activity was significantly disrupted by placing animals in cages with fresh bedding or nesting material, or by performing both of
these manipulations concurrently during the light period. These findings suggest that standard husbandry practices and common housing conditions may transiently affect core temperature in adult mice. Furthermore, these practices may have profound and relatively long-lasting effects on motor
activity and the regulation of circadian rhythms.
