ABSTRAK Perairan Teluk Semarang merupakan pantai utara Jawa yang terbentang dari Kabupaten Kendal hingga Kabupaten Demak. Perairan ini dekat pelabuhan Tanjung Mas dan pemukiman, berbagai macam industri, sehingga berpotensi tercemar berbagai jenis limbah. Salah satu jenis limbahnya adalah logam berat. Kerang Simping merupakan biota filter feeder dan sessile, sehingga logam berat di perairan akan terakumulasi pada sedimen dan tubuh kerang melalui rantai makanan. Osmoregulasi merupakan upaya hewan air mengontrol keseimbangan ion di dalam tubuh dan lingkungannya. Hal ini menjadi alasan penelitian dilaksanakan untuk mengetahui konsentrasi logam Cd pada kerang Simping dan sedimen di perairan Teluk Semarang dan hubungannya dengan tingkat kerja osmotik. Metode yang digunakan adalah metode deskriptif dan korelasi dengan penentuan lokasi sampling menggunakan metode purposive sampling. Penelitian dilakukan pada bulan Mei 2019. Hasil penelitian menunjukan konsentrasi logam Cd pada jaringan lunak kerang Simping di perairan Teluk Semarang adalah sebesar < 0,00001 mg/kg. Hal ini menandakan bahwa logam Cd yang terkandung dalam kerang Simping sangat kecil sehingga tidak terdeteksi oleh alat. Logam Cd pada sedimen di perairan Teluk Semarang tiap stasiunnya memiliki nilai rata-rata sebesar: 82,2057; 58,4483; 68,0787 mg/kg. Hubungan logam Cd pada sedimen dengan osmolaritas hemolimfe kerang Simping menunjukkan hubungan hubungan linier bersifat positif dengan nilai R2 sebesar 0,259 yang artinya tingkat keeratan rendah. Hubungan logam Cd pada sedimen dan tingkat kerja osmotik memiliki hubungan linier yang bersifat negatif dengan nilai R2 sebesar 0,236 yang artinya tingkat keeratan rendah. ABSTRACT The waters of Semarang Bay are the northern coast of Java which stretches from Kendal Regency to Demak Regency. These waters are near the port of Tanjung Mas and settlements, various industries, so that it is potentially polluted by various types of waste. One type of waste is heavy metal. The scallop is a biota filter feeder and sessile, so that heavy metals in the water will accumulate in the sediment and body of the shell through the food chain. Osmoregulation is an attempt by aquatic animals to control the balance of ions in the body and its environment. This is the reason the research was carried out to determine the concentration of Cd metal in scallops and sediments in the waters of Semarang Bay and their effect on the level of osmotic work. The method used is descriptive and correlation methods by determining the sampling location using purposive sampling method. The study was conducted in May 2019. The results showed the concentration of Cd  in soft tissue of scallop shells in Semarang Bay waters was <0.00001 mg / kg. This indicates that the Cd metal contained in the scallop is so small that it is not detected by the tool. Cd metal in sediments in the waters of Semarang Bay each station has an average value : 82.2057; 58,4483; 68.0787 mg / kg. The relationship of Cd metal in sediments with hemolymph osmolarity of scallops showed a positive linear relationship with an R2 of 0.259, which means a low level of closeness. The relationship of Cd metal on sediment and osmotic work rate has a negative linear relationship with R2 value of 0.236, which means a low level of closeness.

Otolith or ear stone of fish,  known as a result of biomineralization which takes place in the body of the fish. In some studies, otolith used to estimate age and stock structure of the fish.  The otolith  was categorized into three  types called sagitta, lagena and utrikulus and  the most widely studied. This study was designed to describe the characteristics  of the otolith of S. crumenophthalmus  by implementing  six index form descriptors.Tthe  study also dimed at determinition the relationship of fish length and otolith length as well as otolith width .  Linear regression approch was used to analyse the relationship of fish length and whole characteristics otolith . Those parameters were analysed using Excel and application R program  ( the package the FSA ). The results  show that otolith S.crumenophthalmus  sagitta has 6 descriptor indicees thatt are as follow: 1) the irregular surface (from factor < 1), 2) comparison against a full round (roundness ≠ 1), no 3) (full circle-shaped circularity: 21), 4) do not form a perfect square (R ≠ 1) and 5 axis) changes of 28-29 and 6) form a somewhat elongated (aspect ratio > 1). The value index  otolith form is showed ellipse.Based on the results of the analysis, the otolith left and right (length, width, perimeter, and area) otolith males S. crumenophthalmus has no different. Same alsois found on the case of males otolith, left and on right (long) females otolith S. crumenophthalmus does not differ except the width of the otolith, the area and perimeter size of a different otolith real. The relationship between  the length size and width dimensions of otolith with the total length of the fish has a linear relationship. The second parameter of the linear relationship is marked by the determination coefficient values on otolith length varies between 0,56-0,62 and its width ranged from 0.49 to 0.69. For female fish, otolith lenght detemination coefficient varies between 0.27 and 0.25 to its width ranges from 0.15 to 0.19.Key words: S.crumenophthalmus, otolith Morfometrik, Gulf of Kema AbstrakOtolit atau batu telinga ikan dikenal sebagai hasil dari biomineralisasi yang berlangsung dalam  tubuh  ikan.

The book’s epilogue explores the place of musical portraiture in the context of posthumous depictions of the deceased, and in relation to the so-called posthuman condition, which describes contemporary changes in the relationship of the individual with such aspects of life as technology and the body. It first examines Alfred Hitchcock’s Vertigo to view how Bernard Herrmann’s score relates to issues of portraiture and the depiction of the identity of the deceased. It then considers the work of cyborg composer-artist Neil Harbisson, who has aimed, through the use of new capabilities of hybridity between the body and technology, to convey something akin to visual likeness in his series of Sound Portraits. The epilogue shows how an examination of contemporary views of posthumous and posthuman identities helps to illuminate the ways music represents the self throughout the genre of musical portraiture.

From Plato and Aristotle, Hippocrates and Galen, through the medieval commentators, the Elizabethans inherited a body of complex psychological principles. An examination of these principles and their bearing on The Faerie Queene has so far been only casual and incidental. Since in Book ii, Canto ix, the poet combines one of the most widely used of medieval motifs—the conception of the body as a world, city, or castle—with certain current doctrines of psychology, such an inquiry is especially apposite. Spenser's use of the abundant contemporaneous literature of psychology affords material for an extended treatment such as that which Miss Anderson has made of Shakespeare's plays. The present study purposes to set forth one aspect of his system of psychology—his psychology of memory in the allegory of the Castle of Alma, to make clear the relationship of his system to the current Elizabethan doctrines, and to establish the purpose of certain departures from those doctrines.

Undifferentiated mesenchymal (UM) cells, the progenitor cells of the cartilage layer, have been assigned a significant role in TMJ articular tissue maintenance. This was based on reports of UM cell reduction with increased soft-tissue thickness for the condyle and temporal component. However, the strength of this inverse relationship was not presented and remained unclear. The purpose of the present study was to assess the strength of the correlation between UM cell presence and soft-tissue thickness in young adult TMJs at autopsy. Sagittal histological sections from the central thirds of 50 joints were evaluated with respect to articular soft-tissue thickness, histological character, and UM cell presence in the condyle and temporal component. The superior sector ofthe condyle and the articular eminence showed the greatest variability in soft-tissue thickness and were the only areas to show localized UM cell absence. The eminence was the only location to show an inverse relationship between soft-tissue thickness and UM cell presence, and this was consistent in both an ANOVA (p = 0.0016) and a Spearman correlation analysis. However, the strength of this correlation was only moderate (rho = -0.52), and no such relationship was observed in any other location. This study suggests that the relationship between UM cell presence and soft-tissue thickness is more complex than previously hypothesized and that the contribution of UM cells to articular tissue maintenance has been overstated, while other biological processes were overlooked.

This article investigates the significance of the manuscripts of Virgil and other classical poets that Dante might have read. Calling attention to the presence of musical notation (neumes) in copies that share the particular Virgilian readings Dante quotes, this essay explores the resonance of one of those passages (Aeneas’ dream of Hector) in Dante’s poem. It shows how Dante uses this Virgilian episode to craft his encounter with Manfred where he considers the relationship of body and soul that constitutes one of the major differences between classical and Christian thought, as Augustine frequently noted. Just as Christian anthropology maintains that the body constitutes an essential element of the human person, this essay argues that the materiality of the texts Dante read constitutes a crucial source for understanding how Dante interpreted these texts.

1. Thirty Suffolk × Half bred lambs were slaughtered at the following ages: two twin lambs at birth and two singles and two twins at 1, 2, 3, 4, 6, 8 and 16 weeks of age.2. The following weights were recorded: live-weight immediately before slaughter; and carcass, head, skin, feet, alimentary tract, heart, liver, kidneys, lungs and trachea, and blood immediately afterwards.3. The alimentary tract was emptied and weighed in four separate parts; reticulo-rumen, omasum-abomasum, small intestine, large intestine.4. The volumes of the reticulo-rumen and the omasum-abomasum were measured by immersing in water and filling the organs with water to 2 cm. pressure.5. The in vitro digestive efficiency of rumen liquor from lambs of 1, 2, 3 and 4 weeks of age was assessed.6. Empty body weight was considered to be valuable in comparing animals of different ages or from different feeding regimes or at different times of the year because variations in gut ‘fill’ were eliminated.7. There were no differences between singles and twins in the relationship of the fresh weights of the parts of the body to empty body weight, except that development of the liver and the blood was rather slower for singles.8. Little evidence was found of a difference in rate of development of the alimentary tract between singles an d twins, although the log an d square root transformation suggested a possible difference in reticulo-rumen size in favour of twins, significant at the 5% level.

Since the beginning of humanity, an attempt has been made to explain the way in which man acquires knowledge, the way in which he assimilates, processes and executes it in order to develop the teaching-learning process that people need throughout of his life, which forces to change the learning schemes using new study methodologies, such as neuroscience, which is a discipline that studies the functioning of the brain, the relationship of neurons to the formation of synapses creating immediate responses which transmits to the body voluntarily and involuntarily, in addition to controlling the central and peripheral nervous system with their respective functions. It is necessary to change the traditional scheme and implement new strategies that allow the teacher to venture into neuroscience, in order to individually understand the different learning processes that students do. As some authors of neuroscience say, the brain performs processes of acquisition, storage and evocation of information, which form new knowledge schemes that generate changes in the attitude of the human being, for this reason teachers are responsible for taking advantage of what It is known about the multiple functions of the brain and be clear about the various ways of acquiring knowledge.

The study in this paper are explain about the studies of medical (medicine) blood type have the same relationship to human character because the blood producing antibodies and antigens. It could determine a person helpless hold strong or weak body, has an allergy to something or not, in the blood also contains various nutrients (like protein) and also the oxygen being supplied to the brain and nerves and body affect performance someone will then be emanated from the attitude of the person and social interaction. As has been explained, but keep in mind, there is blood in the genes, the nature of which is carried in the body/genotif rightly so it is, but we can not ignore the fenotif/nature arising or visible, this trait appear due to interaction between genes and the environment, so even if the person is smart in the intelligentsia and emotional, but grew up in a bad environment is going to be a bad trait. The theory of personality based on blood type can be used as a reference in parenting children through an understanding of the fundamental principles of the application of personality accompanied by parenting. Furthermore, the taking of steps in the care tailored to the stage of development of the child, in the Qur'an explicitly did not mentioned paragraph that discusses about blood type, but in the Qur'an there are blood (ad-Dam), Islamic studies in the study of Children is seen as a mandate from God, forming 3-dimensional relationships, with parents as the central figure. First, her parents relationship with God that is backed by the presence of children. Second, the relationship of the child (which still need a lot of guidance) with God through his parents. Third, the relationship of the child with both parents under the tutelage and guidance of God.
