The Nd-Fe-B anisotropic magnetic powders were subjected to tempering and ball milling processes. Analysis of the magnetic properties, structure, and physical phase revealed that the following: the integrated magnetic properties of the magnetic powder were the best when the tempering temperature and time were separately 650 °C and 20 min, for DOA = 0.73, Br = 6.547 kGs, Hcj = 12.255 kOe, and (BH)max = 7.117 MGOe. When the DR temperature is 860 °C, the tempering temperature is 650 °C, and the tempering time is 20 min, the ideal magnetic properties of the magnetic powder are DOA = 0.69, Br = 6.238 kGs, Hcj = 14.67 kOe, and (BH)max = 7.060 MGOe. The integrated magnetic properties of the magnetic powders were optimal when the ball milling speed, time, and doped Cu content were 350 rpm, 2 h, and 10 wt%, for DOA = 0.62, Br = 4.96 kGs, Hcj = 9.86 kOe, and (BH)max = 4.39 MGOe. The ideal tempering temperature and time can promote the diffusion of Nd-rich phase to the grain boundaries, strengthen the pinning effect on the magnetic domains, and improve the coercivity of the magnetic powder. The ideal ball milling speed and time can effectively reduce the particle size of the main phase particles of the magnetic powder and the large particles of the Nd-rich phase, so that the Nd-rich phase is uniformly distributed at the grain boundaries, to achieve the effect of de-magnetization coupling and improve the coercivity of the magnetic powder. After ball milling the magnetic powder doped with an appropriate amount of Cu powder, Cu induces the precipitation of a certain amount of Nd in the main phase of Nd2Fe14B. This Nd is uniformly distributed at the grain boundaries, achieving the effect of repairing the grain boundaries, thereby improving the coercivity of the magnetic powder. [ABSTRACT FROM AUTHOR]

The utilisation of plant-based temper in Songze culture pottery incorporated a substantial proportion of fibre and exhibited a microstructure resembling a fully oxidised rice husk temper (Grog). However, during the Liangzhu and Guangfulin periods, these plant-based tempers underwent a transformation into quartz and other mineral tempers. Notably, amphibole tempers were identified in pottery from the Liangzhu culture, particularly in black pottery coatings. The structure of the low-aluminium ceramic coating was determined to be porous, and initially, this type of temper was thought to be debris resulting from jade processing. However, experimental archaeological studies have demonstrated that it is difficult for jade fragments to develop a similar petrographic structure. In pottery from the Guangfulin culture, white pottery coatings turned black when compacted. This colour alteration may have been achieved through simple sintering processing, suggesting the potential utilisation of a two-step pottery processing technique under low-fire conditions.

Abstract Results from petrographic and chemical analysis of decorated Lapita pottery from Vao, Vanuatu show that the majority was manufactured locally but that several variations of local raw materials were used. This indicates that temper material was collected from a range of settings, most of them accessible locally on Malakula. Two samples have temper corresponding with raw materials expected from the island of Efate in central Vanuatu where other significant Lapita sites are located. This pattern of fabric variability parallels recurrent practices documented at other founder Lapita sites, including Teouma on Efate. We propose that mobility and experimentation are not the only explanations available to justify the greater initial variability in raw materials used for pottery manufacturing at founder Lapita settlements. We argue that the variability of raw material results from a purposeful strategy guided by cultural norms or rules similar to those directing other behaviors associated with decorated Lapita pots, such as decorative motifs, paint application, vessel forms, and deliberate burial.

BACKGROUND: This study aimed to investigate the effects of semidry milling on the quality attributes of highland barley flour and highland barley bread. Highland barley flours were prepared by dry (DBF), semidry (SBF), and wet (WBF) milling methods. The properties of different highland barley flours were analyzed, and highland barley breads made from different highland barley flours were evaluated. RESULTS: The results showed that WBF had the lowest damaged starch content (15.2 g kg−1), and the contents of damaged starch in SBF‐35 and SBF‐40 (43.5 g kg−1 and 24.1 g kg−1 respectively) were lower than that of DBF (87.6 g kg−1). And SBF‐35 and SBF‐40 with large particles exhibited low hydration performance. In addition, SBF‐35 and SBF‐40 had higher pasting viscosity, pasting temperature, ΔH, and relative crystallinity, consequently resulting in better gel properties than other highland barley flours. These properties could help SBF‐35 and SBF‐40 develop high‐quality bread with large specific volume and superior crumb structure and texture that is similar to the bread with WBF. CONCLUSION: Overall, semidry milling not only could improve the characteristics of HBF, but also avoid high starch damage by dry milling and water wasting by wet milling. What is more, highland barley breads with SBF‐35 and SBF‐40 had preferable appearance and crumb texture. Therefore, semidry milling could be regarded as a feasible way to produce highland barley flour. © 2023 Society of Chemical Industry. [ABSTRACT FROM AUTHOR]

The intent of this statistical implication in the diamonds’s galaxy is to pinpoint where will be placed in future the level of the global natural diamonds production, in other words if this level will be in regression. The diamonds have a lot of usages, such as: for to slice the rock, faiance and slate, for to gloss the rock, at making of the chips and hard disks in the computer’s sector, for to create lens used at the equipment weared when the laser is manoeuvred. If we want to modify the diamonds’ colours, we can utilize the technological processes applied in the nuclear reactor, respectively in the particles accelerator.

The study presented here deals with the manufacturing technologies of cooking pots in Iron Age II Judah (ca. 1000–586 BCE). Two aspects were studied on an assemblage of ca. 500 cooking pots: paste preparation with a highlight on temper analyses as well as fashioning and finishing techniques. The research is conducted as a part of a substantial multi-disciplinary study of cooking ware in Iron Age Judah, combining technological, typological, petrographic, and chemical aspects. New cooking pot types appeared during the Iron Age II, with the apparent existence of regional production centers for cooking pots in this period. The results indicate that the cooking pots were made following three technical groups, reflecting a stable technical and technological continuity alongside the rise of specialized production in various regional production centers. Temper analysis carried out through petrography shows a slow shift from calcite-calcareous tempering towards quartz tempering (which may be partly or entirely naturally present in the clay selected). These results will also be discussed in relation to the morphological typology of the vessels and petro-fabrics identified in the more extensive study. Resting on several analytical methods, this paper aims to characterize the cooking pot production system, thus providing insights into Iron Age Judah’s pottery craft organization.

Studies of technological change over time arrived late in the discipline. Hence, pottery studies call for shedding more light on composition, which includes temper that was only sporadically studied. The Neolithic of Egypt was described as not being well understood. Therefore, this paper dealt with temper in pottery vessels during the Neolithic of the Nile Valley in the cultures of Fayum, Merimde, el-Omari and Badari. Previous studies identified the additives in the fabric of the pottery, but without paying attention to the function and uses of those pottery vessels, this research paper determined the relationship between these materials and the uses of the pots as individual human behavior with which there is a direct relationship with social behavior, as well as the relationship between the materials added to the pottery vessel and the decorations implemented on it. This study traced the development of temper using descriptive and analytical theoretical frameworks, namely design structure analysis. Results confirmed that temper changed and developed overtime. Fayoum pottery was tempered with plant and mineral material. Even within the same culture, like in the case of Merimde, temper changed from un-tempered clay with polished surfaces, then later adding temper. The latter practice resulted in rougher pots with fewer decorations and more forms. The red color was sometimes added as a temper to pottery from el-Omari. Badari pots showed the use of particular Nile fabrics: A, B, and C, reflecting the specific use of vessels, which coincided with an increase in social complexity and the development of pottery production within the society. This study confirmed that pottery temper could be studied from an artistic perspective.

Introduction: The aim of the study is to determine basic physical traits of physiotherapists and indicators of their occupation according to social expectations. Material and Methods: 2121 people of different sex, age and education participated in the study. The preferences were categorized by sex and the education level. The test for equality of two percentage structures based on statistics ‘Z’ and the test for equality of proportions based on Fisher-Snedecor’s test were implemented. Results: The preferences for the physical traits are consistent with those commonly expected, and the high level of fitness is expected in the context of significant psychological and physical burdens. The respondents’ education level rather than gender seems to be a more significant variable in the evaluation of personal characteristics. The most significant differences can be noticed in the choices of people with a low level of education. Conclusions: Sex and education influence the preferences regarding the build of a physiotherapist and the characteristics of their job, and the results of the most important appearance attributes and body build clearly show a lack of social acceptance of therapists who neglect their appearance.

This article uses Richard Ligon's opening figure of clay pots found by colonizers on Barbados to develop a theory of the emblematic combustibility figured in the natural history he writes of the island. Clay pots need to be tempered to withstand firing, but, as Ligon states, colonizers don't have this knowledge of tempering, and the bricks they try to make to establish plantations keep exploding. I use the idea of this combustibility to trace various forms of multispecies violence inherent in the mono-cultural practices Ligon records. From racial slavery to ecocide to land dispossession, this violence registers in emblems that demonstrate an epistemological commitment to that violence, as well as the work of erasure and forgetting necessary for upholding the accumulation of wealth, power, and the fantasy of white innocence inherent in the history of the plantation complex.

Background: Individuals learn in different ways and likely they express their strengths. Gardner's assertion, if everyone will have the same kind of mind and there would be just one type of intelligence, then we can teach everyone the same thing, in the same way; as well, we will assess them in the same way, and this would be fair. But, as soon as we understand that people have a variety of types of minds, different types of strengths, education, which treats everyone in the same way, is unfair education. Purpose: of this work is to give a definition and meaning to multiple intelligence and identify its implications in good manners and education. Method: will be literature research in the form of a metaanalytical analysis form and comparative including/melting the pedagogical and psychological studies. [ABSTRACT FROM AUTHOR]

Abstract A collection of pottery vessels uncovered during the first season of excavations in the Deh Dumen Bronze Age graveyard (the second half of the third millennium BC) located in south-western Iran were studied by using chemical, mineralogical and physical techniques, with the aim to identify the pottery manufacturing process in this region. The site is located in a region of the Zagros fold and thrust belt that includes carbonate rocks and alluvial deposits. The pottery vessels found in the site present two different fabric types in their fresh surface: bright yellowish hue fabric (TYPE-1) and sandwich-like or black core fabric (TYPE-2) showing presumably different production techniques or workshops. Twenty-four samples from pottery sherds were selected and analysed by X-ray fluorescence (XRF), powder X-ray diffraction (XRD), polarized light microscopy (PLM), and field emission scanning electron microscopy (FESEM). Hydric tests were also performed. Samples were different according to their chemistry having distinguished calcium-rich and calcium-poor ceramics. Al2O3 and Fe2O3 were detected as the other main components of samples besides SiO2 and CaO. The mineralogical and textural characterisation revealed a fine-grained clayey matrix with quartz and feldspar grains in TYPE-1 potteries and large and small calcitic and clayey lumps inclusions in TYPE-2 potteries. Imprints of straw or other plants can be responsible for the higher porosity of some of the potteries. It was found that most of the potteries from the Deh Dumen graveyard were produced by means of a local and traditional pottery manufacturing technique, whilst others may have been produced in different places and transported to the graveyard as ritual offerings.

Archaeological finds at Spasovine, on the south flank of Mt Cer, near the town of Milina, indicate that it was settled in the Eneolithic and seasonally inhabited for tin placer mining in the Late Bronze Age. The site is highly disturbed and abraded domestic pottery is the most common material found. An analysis of the mineralogical assemblages that comprise the temper sand in a subset of the prehistoric pottery sherds from the site indicate that the sand was obtained from the adjacent Milinska River. Key minerals that link the pottery to on-site production from local materials include almandine-spessartine series garnets, the tin-bearing mineral cassiterite (SnO2) and a microlite group mineral ([Ca,Sn,U]2[Ta,Nb]2O6(OH,F]). The unusually common occurrence of cassiterite within the pottery sherds relative to the abundance in the Milinska today suggests that the tin ore grade in the Milinska River may have been significantly higher in prehistory.

This study evaluated whether a theory‐based intervention in physical education (PE) designed to train self‐control may positively impact children's quick‐temperedness and disruptiveness and whether changes in executive functions (EFs) may be a correlate or antecedent of such effects. One hundred and sixteen children aged 8–9 years participated in a 2‐year intervention and completed three assessments at baseline, 6‐ and 18‐month follow‐ups in quick‐temperedness and disruptiveness, hot and cool EFs. After the intervention, children in the intervention group showed lower quick‐temperedness and disruptiveness and improvement in hot EF. Changes over the intervention period were moderately associated and showed marginal evidence of causal ordering, suggesting that designed PE may benefit self‐control through a possible linkage to hot EF improvement.

The present article is a meta-analysis of existing literature regarding the relationship between personality and physical activity. The interest of specialists for the role of the athlete's personality in achieving sports performance is highlighted by various studies and research. However, it was not possible to establish a certain "standard" for the personality of the athletes who achieve great sport performance, but a number of common features were revealed. On the other hand, the second direction of this meta-analytical study regards personality development based on its classical structure, temper, skills and individual character of sport practicing subjects.

Amphorae sherds from the Laecanius workshop of Roman Istria (10–5 B.C. and 78 A.D.), Croatia, were studied by integrating archaeological and geological techniques including fabric analysis, thin-section petrography, X-ray diffractometry (XRD), and heavy mineral analysis. The fabric of the sherds showed distinctive characteristics, permitting their classification and allocation into nine fabric groupss. Petrography revealed that quartz is the dominant clastic component, whereas carbonate is common as temper; XRD provided information on firing temperatures that ranged between 750 and 900°C. The sherds contain diverse heavy mineral suites with generally high epidote and garnet proportions; zircon is occasionally important. Garnet/epidote ratios and the presence of diagnostic species (pyroxene, hornblende) showed systematic variations that coincided with similar variations in fabric characteristics. Heavy mineral signatures of amphorae produced in other workshops proved essential in differentiating them from Laecanius sherds. A comparative heavy mineral analysis of terra rossa samples from the vicinity of the workshop indicated that terra rossa was the major source for the paste. Differences observed in the heavy mineral composition of the sherds and terra rossa were interpreted by the spatial heterogeneity of the latter and the mixing of the paste with sandy temper. Fresh Adriatic sponge spicules in the majority of Laecanius sherds and the temper-derived, generally immature heavy mineral assemblages suggest that sandy deposits from the Adriatic were used for the clastic temper.

Alceo fr. 369 Voigt (= 369 Liberman) ha recibido poca atención. Ateneo de Náucratis lo conservó y Eustacio de Tesalónica sintetizó su contenido. Estos dos escritores suponen que el fr. 369 significa que a veces beber vino suaviza el carácter y a veces lo exacerba. Pero es probable que ni Ateneo ni Eustacio leyeran nunca el poema completo de donde proviene el fragmento. Hay que rechazar tambien las interpretaciones que han propuesto los estudiosos modernos (Page, Liberman), porque no tienen en consideración la alternancia expresada en el paralelo ἄλλοτα μὲν..., ἄλλοτα δ᾽... . Además, hay que rechazar una interpretación literal del fragmento, ya que es absurdo imaginar que hombres del ambiente de Alceo pudiesen beber vino malo o vinagre. El autor del presente artículo sugiere una interpretación alegórica a la luz de la «ley de la mutación eterna» o «ley de la alternancia»: a veces se encuentran días afortunados, a veces días infaustos.

Determination of rational drying modes of seed grain is related to the kinetics of the drying process and qualitative indicators. Changing the drying conditions affects the drying process duration, and also affects the seed germination. The mathematical processing of experimental data on the drying of rape seeds is based on experimental studies and the compilation of an experiment matrix based on three factors: the temperature and velocity of the heat carrier, the initial moisture content of the material. Selected variation levels or the boundary conditions of these factors are based on qualitative indicators, initial seed conditions before drying. Studies carried out on increasing the temperature of the coolant from 50° to 80°C increase the drying rate by 2.4 times, but reducing the germination of the material indicates the advisability of drying at 50°C. The obtained regression equations of duration and germination characterize the processes, proceeding from the effect of three factors with the exception from the equation of non-significant coefficients of the regression according to Stewdent's criterion. It also examines the adequacy of the mathematical model, that corresponds to the real object. The change in the acid number substantially increases at the coolant temperature of 80°C, but it is normal. [ABSTRACT FROM AUTHOR]

Combining choirs for a large-scale performance can be rewarding. If the choirs comprise different generations, differing vocal timbres can add musical possibilities. A school in London operates two choirs in partnership: one for adult members of the school community and a student choir. They perform large-scale works together regularly. Interviews were undertaken with adults to understand their experience of the partnership. Frequently research explores students' engagement but rarely are the views of adults sought. Intergenerational music-making involves challenges such as participants working collaboratively and not in competition. Participants in this case study discuss the impact of singing in a choir with sons or grandsons and implications for family and community cohesion through music-making are explored.
