SUMMARYData were obtained from 27 pure Shorthorn, 22 Angus × Shorthorn, 31 Charolais × Shorthorn and 27 Hereford × Shorthorn cows, during 10 years. Angus × Shorthorn cows required the least number of services per conception (1·17), had the shortest average gestation lengths (280·6 days), and had a calving percentage of 88·2% and birth weight of calf of 29·8 kg. The respective figures for Charolais × Shorthorn were 1·21 services, 281·6 days, 88·3% (the highest) and 32·9 kg (the heaviest), for Hereford × Shorthorn 1·23 services, 283·6 days, 84·4% and 31·6 kg, and for pure Shorthorn 1·20 services, 282·2 days, 82·7% and 29·6 kg. Average calf weight at birth increased with the advance in age of cow up to 5 years, then showed little change. Seventy-two per cent of the crossbred cows calved for the first time at 2 years old compared with 65% of the Shorthorns. On the other hand, Shorthorn cows had the highest twinning percentage (2·9%) and the lowest single calf mortality at birth (1·4%). The maximum body weights of Angus, Charolais, and Hereford crossbreds and Shorthorn cows were 576·8, 655·8, 6254 and 553·8 kg respectively at 7–8 years of age.

The present investigation was carried out to detect the status of different productive and reproductive parameters of Black Bengal and Crossbred goats at Bandaikhara village under Atrai Upazilla of Naogaon district during the period of September to December/2005. The average age at first sign of heat of Black Bengal goats was better than that of Crossbred goats. In Black Bengal goat the average age at first kidding was 360.5±10 days, whereas, in crossbred goats it was 411.5±15.5 day. Significantly (P<0.01) lower the post partum heat period in Black Bengal goat than the crossbred goat. The average kidding interval in Black Bengal and Crossbred goats were 179±20 and 270±22 days respectively and differences are statistically significant (P<0.01). The usual numbers of kids at one time in Black Bengal goats vary from single to quadruplet. On the other hand, litter size of crossbred goat was single or twin. The average birth weight of Black Bengal goat was lower than Crossbred goats, which are statistically significant (P<0.05). The average body weight gain after 365 days is better in Crossbred than Black Bengal goats and statistically significant (P<0.01). The average milk yield in Crossbred goat was 1.05 liter/day, whereas, in Black Bengal goat, it produces milk that only nourished its kids. It was concluded that the reproductive performance like early maturity, larger litter size, shorter postpartum period, minimum kidding interval are better in Black Bengal goat. On the other hand productive performance like higher birth weight, maximum body weight gain, high milk yield, longer lactation length are suitable in crossbred goat.

Body weights and measurements were compared among several genetic groups from the 496 Holstein-based H line heifers and 344 Ayrshire-based A line heifers. Differences among herds (Charlottetown, P.E.I., Lennoxville and Normandin, Que.; Ottawa, Ont., and Lethbridge, Alta) were large and highly significant (P < 0.01) for age at first calving and all weights and measurements except birth weight. Year and season of birth effects were small and generally not significant (P > 0.05). Birth weights were 4.1 kg lighter for calves from first parity dams and 1.4 kg lighter for second parity dams than fourth or later parity dams. Heifers calving at earlier ages for the first time were generally heavier and larger at 66 and 82 wk than those calving later, reflecting the effects of concurrent pregnancy. H line heifers were significantly heavier and larger in all measurements than A line heifers. Differences among the Canadian, American, and Research Branch Holstein sire groups were small and generally not significant (P > 0.05). Brown Swiss progeny were significantly (P < 0.05) taller at the withers and longer in the rump and generally larger than progeny of other A line sire groups. Norwegian Red progeny were the most similar to the Brown Swiss, followed by the other Ayrshire groups. Key words: Growth, heifers, Holsteins, Ayrshires, Brown Swiss, Norwegian Red

Al-Qusayr is located 40 km south of modern al-Wajh, roughly 7 km from the eastern Red Sea shore. This site is known since the mid-19th century, when the explorer R. Burton described it for the first time, in particular the remains of a monumental building so-called al-Qasr. In March 2016, a new survey of the site was undertaken by the al-‘Ula–al-Wajh Survey Project. This survey focused not only on al-Qasr but also on the surrounding site corresponding to the ancient settlement. A surface collection of pottery sherds revealed a striking combination of Mediterranean and Egyptian imports on one hand, and of Nabataean productions on the other hand. This material is particularly homogeneous on the chronological point of view, suggesting a rather limited occupation period for the site. Attesting contacts between Mediterranean merchants, Roman Egypt and the Nabataean kingdom, these new data allow a complete reassessment of the importance of this locality in the Red Sea trade routes during antiquity.

1. In their fundamental paper of 1949, Higman, Neumann and Neumann proved for the first time that a countable group can always be embedded in some 2-generator group: [1], Theorem IV. Two kinds of improvement of this result have recently appeared. In [4], Theorem 2, Dark has shown that the embedding can always be made subnormally. On the other hand, in [2], Theorem 2.1, Levin has shown that the two generators can be given preassigned orders m > 1 and n > 2; and in [3], Miller and Schupp prove that the 2-generator group can also be made to satisfy several additional requirements, such as being complete and Hopfian.

For the first time, in the article, Vladimir Titov’s letter (dated 12/24 February 1869) is published and commented. In the 1820s, in Russia, Titov was well-known as a writer and literature theorist, the author of a romantic novella The Remote House on Vasilyevsky Island (1829) close to Society of Lyubomudriye. The letter extracted from the archives of the National Library of Russia is addressed to Duke Vladimir Odoevsky whose relationship with Titov was friendly from the very beginning of their acquaintance. The letter focuses on Ivan Turgenev’s speech published in the first issue of Sovremennik and titled “Hamlet and Don Quixote”. Reacting to Turgenev’s article, Titov shortly and critically accesses the comparison concentrating mainly on the image of Hamlet and thoroughly expresses his opinion on the essence of his tragic state. Titov’s opinion is just the opposite of Turgenev’s complex and multidimensional interpretation. Having experienced the great impact of the philosophy of German idealism at the beginning of his career, Titov to a great extent idealizes Shakespeare’s character whom he long knows and whom he is clearly eager to vindicate. Meanwhile, Titov does not pursue the aim to absolutely advocate the romantic halo of Hamlet as a Titanic personality (grandiose intellect and scale of feeling) and to enact the tragic pathos of the inner fight only. Developing Goethe’s definition of the essence of the character’s inner conflict, Titov, on the one hand, approaches its real understanding underlying the prince’s necessity to stay in a derogatory position of a “pitiful semiclown, indecisive grouch and shred”. On the other hand, the assessment can not be absolutely objective because Titov wants to see Hamlet as a victim of the fatal fortune which turns him into a character of an almost classical tragedy of fate. Titov’s bright and developed reaction (in the document of private nature) to Turgenev’s article is attractive and important first of all for its vividly demonstrated novelty and creativity of the writer’s view, wideness and multimodality of the author’s perception of Hamlet’s image. For the first time, Turgenev gave a developed interpretation of Shakespeare’s image in the tale “Hamlet of Shchigrovsky Province” (1848). Continuing his searches in the area of “Russian” (or “steppe”) Hamlet, Turgenev creates moral and philosophical problems of the English tragedy in the crisis socio-historical and cultural atmosphere of Russia of the 1840s. However, the principles of the artistic generalization and the peculiarities of the new reading, not mentioned and not fully comprehended by his contemporaries, were surprising and rejected when the speech “Hamlet and Don Quixote” appeared, in which Shakespeare’s character is presented ultimately vividly and lively in the then current interpretation.

The paper examines two key novels by Sandro Veronesi, the modern Italian writer, Calm Chaos (2006) and Colibri (2020). Both novels were awarded Italy’s main literary prize, the Premio Strega, which is a unique precedent. The relevance of the article comes from the high demand for research on contemporary Italian literature on the one hand and from the novelty of the proposed interpretation for the novel Calm Chaos on the other hand. For the first time, the protagonist of Calm Chaos, Pietro Palladini, is presented not as a preacher of eternal values, returning the reader to the theme of knowing oneself and the surrounding world, but as a mad visionary with clear signs of psychopathy and schizophrenia. The analysis of Veronesi’s latest novel Colibri reveals the character’s evolution and the writer’s narrative manner. The theme of psychiatry in the life of a modern person appears to be one of the key ones in Veronesi’s work.

This chapter first discusses the two roots of copyright. On the one hand, copyright began as an exclusive right to make copies—that is, to reproduce the work of an author. This entrepreneurial side of copyright is linked in with the invention of the printing press, which made it much easier to copy a literary work and, for the first time, permitted the entrepreneur to make multiple identical copies. On the other hand, it became vital to protect the author now that his or her work could be copied much more easily and in much higher numbers. The chapter then outlines the key concepts on which copyright is based.

It is now a well established fact that high-level nutrition of the in-lamb ewe during the later stages of pregnancy results in heavy lambs of high vitality at birth and in good milking ewes. On the other hand, when ewes are poorly fed during the same period, or suffer a check, they produce underweight lambs of low vitality and have poor milk yields. While it is agreed that underweight lambs are undesirable, one is often asked whether the larger and sturdier lambs at birth maintain their superiority in later life, a problem on which relatively few results have been published. A study has therefore been made of a large number of birth and weaning weights collected as a normal routine at the Rowett Institute during the past few years.

The three larval instars of Suphis cimicoides Aubé, 1837 are described and illustrated, including morphometric and chaetotaxic analyses of the cephalic capsule, head appendages, legs, last abdominal segment and urogomphus. A preliminary ground plan of primary chaetotaxy for noterid larvae is presented for the first time, based on the species described herein and examination of larvae of the genera Hydrocanthus Say, 1823 and Suphisellus Crotch, 1873. This ground plan is compared with previous systems proposed for other adephagan families. Larvae of Noteridae can be distinguished from those of other families of Hydradephaga by the following combination of characters: (1) antennomere 3 with a rugged area on distal portion; (2) abdominal segment VIII with a U-shaped wavy membranous area ventrally; (3) absence of pore FRd; and (4) presence of seta AB16. Several sensilla present in noterid larvae (notably setae TR2 and TA1 and pores PAl, PAm, COd, TRb and FEb) are absent in larvae of Meruidae. On the contrary, parietal seta PA5 is present in Meruidae but absent in Noteridae. The presence of pore COc in Noteridae may indicate that this family has retained the ancestral condition found only in Carabidae. On the other hand, the absence of setae FE7, FE8, FE9 and FE10 in Noteridae is similar to the condition found in Carabidae, Gyrinidae and Meruidae.
