At least 30 specimens of each form of Macrosiphum rubiellum, Theobald, and Aphis idaei, van der Goot, were collected, mounted and their principal organs measured.Correlations were calculated between different parts on the right side and the conclusion reached that the ratios of lengths of organs were unstable characteristics of the species examined. High correlations were obtained between the same part on different sides of the body.The mean values and standard errors are tabulated and a method given for assigning limits of variation within a species. The standard errors obtained were of the order of 7 per cent. of the mean.The asymmetry, kurtosis and skewness of the distributions were calculated to test the effect of possible non-normality on the foregoing work.

The biochemical composition (proteins, lipid, ash and moisture) of different parts of the body (gill, meat, egg) of fattened and natural mud crab Scylla serrata was determined. Twenty four samples of S. serrata (12 from wild & 12 from fattening farm) of different sizes and sexes (half of the sample is male) were used in this study. The mean protein and lipid contents are significantly (p<0.05) higher in fattened crabs than natural in natural crabs regardless of size and sexes.  Moisture and ash were higher in natural crab than in fattened ones. The highest and lowest moisture content was noticed in gills and eggs in both natural and fattened crabs. Protein and lipid contents were comparatively higher in eggs than in other body parts. Female crabs contained high protein and lipid than males in both natural and fattened crabs.  From the results of this study it may considered that fattened crab might be comparatively superior to natural crabs as they appear to provide higher levels of protein and fat  for human nutrition. Keywords: Biochemical composition; Natural and Fattened mud crab; Scylla serrata   © 2013 JSR Publications.

When it comes to zakat obligations, people only know certain types of zakat that are obligated to be issued. There are two types of zakat; zakat fitrah and zakat property. However, zakat’s division may vary according to the state's fatwa. In Selangor, Lembaga Zakat Selangor (LZS) is the body that governs the administration and implementation of Zakat. The breakdown of zakat property is Zakat on Income, Zakat on Business, Zakat on Savings, Zakat on Gold and Silver, Zakat on Investments and Shares, Zakat on KWSP, Zakat on Paddy, Zakat on Agriculture, Zakat on Wealth and Treasure, and the Zakat on Takaful. However, this study will only focus on Zakat Takaful. Under Zakat Takaful, there are several divisions which are Zakat Wang Takaful/Takaful Investment, Zakat on Maturity Policy, Takaful Compensation, Tabarruq Fund, Benefit of Total and Permanent Disability, and Compensation of Conventional Insurance Policy. Each of these sections has its calculation method which will be explained further. This study was conducted to identify the level of knowledge and acceptance of Takaful Muslim consumers on the implementation of Zakat Takaful that has been introduced by LZS. Besides, this study will also look at the knowledge of Takaful agents and their willingness to disseminate information of Zakat Takaful to their customers. This study was conducted by using the sampling method and descriptive data analysis. The study found that on average, respondents' knowledge on Zakat Takaful is low with a mean of 2.32. However, the mean for acceptance is 3.93 which is set at a high level thus showed a good acceptance of the survey respondents. Through this study, it can be concluded that knowledge and acceptance are both very important in achieving the objective of implementing Zakat Takaful. Knowledge by Takaful participants who are also assisted by agents who play the role of conveying knowledge of Zakat Takaful is directly perceived to have a more effective effect in addition to the behavior/attitude that forms the intention of Takaful participnts to accept the implementation and to pay Zakah Takaful. This study is also expected to be the push factor among the zakat agents to play a role in disseminating the right information about Zakat Takaful to their customers, which also can be regarded as one of the da'wah forms.

Objective: The aim of this study was to evaluate the pterygoid canal (PC) by Cone Beam Computed Tomography (CBCT), establishing its configuration and proximity with anatomical structures. Material and Methods: We evaluated 398 CBCT exams, all from a public University radiology clinic archive. Four parameters were evaluated: single or double PC, distance between PC and the inferior part of the sphenoid sinus (SS), ratio of PC and SS and the distance between the PC and the foramen rotundum. Results: It was observed that most of the PC of the sample presented simple morphology, the most frequent type of relationship between the PC and the SS on both sides was the close contact with the wall. Among the cases that there were some distances between the PC and the inferior wall of the SS, the mean of this distance did not exceed 3.20 mm, being the left side (3.03 mm) slightly closer than the right (3.20 mm). Finally, the distances between the PC and the corresponding Foramen Rotundum are presented with mean values of 5.87 mm for the right side and 6.31 mm for the left side. Conclusion: CBCT examination is of paramount importance for PC identification; once in the studied sample, the mean values found evidence the close relation between the PC and the SS.KeywordsCone beam computed tomography; Endonasal approach; Vidian canal.

<p>Krucyfiks z kościoła Bożego Ciała we Wrocławiu, należącego niegdyś do zakonu joannitów, znajduje się dziś w Muzeum Narodowym w Warszawie. Rzeźba jest różnie datowana przez badaczy, od drugiej do czwartej ćwierci XIV wieku. Dokładny opis formalno-stylistyczny figury z kościoła Bożego Ciała pozwala na uchwycenie właściwości wizualnych, które częściowo potwierdzają postulowaną przez badaczy łączność z czternastowiecznym nurtem c<em>rucifixi dolorosi.</em>Bliskie formalnie rozwiązania sylwetki Ukrzyżowanego pochodzą z różnych terenów europejskich, jednocześnie jednak dzieło wrocławskie jawi się jako osobne na tle przywołanej grupy rzeźb pod względem stopnia wyniszczenia ciała, silnego przechylenia korpusu w prawą stronę, mocnego podkurczenia nóg i poszczególnych detali rzeźbiarskich. Figura wrocławska nawiązuje do zgeometryzowanych form znanych z krucyfiksów bolesnych z pierwszej połowy XIV wieku i jednocześnie w  miękkości wygięcia torsu, w płynności kształtów żeber dostrzec można antycypację stylu pięknego. Zestawienie krucyfiksu z kościoła Bożego Ciała z wybranymi przykładami czternastowiecznej rzeźby śląskiej także wyklucza związki formalno-stylistyczne oraz warsztatowe. Jego wyraz ideowy, pokrewny Piecie z Lubiąża, łączy się ze specyficzną dla drugiej połowy XIII i całego XIV wieku  pobożnością, zorientowaną na rozpatrywanie Męki Pańskiej i indywidualne przeżycie religijne. Choć poszczególne detale rzeźbiarskie właściwie figurze z kościoła joannitów, można łączyć z niektórymi wrocławskimi krucyfiksami, tak ekspresyjne ujęcie ciała nie znajduje sobie równych.</p><p>SUMMARY</p><p>The crucifi x from the Corpus Christi church in Wroclaw, which (the church) used to belong to the Hospitallers of St. John of God, is now the property of the National Museum in Warsaw. According to the art theorists, the sculpture is dated from the second to the fourth quarter of the fourteenth century. The detailed, formal and stylistic description of the sculpture from the Corpus Christi church enables the rendering of visual properties which partially confi rm the suggested connection between this fi gure and the fourteenth-century trend in sculpture known as crucifi xi dolorosi. The formally related structural solutions of the silhouette of the Crucifi ed come from different parts of Europe; at the same time, however, the sculpture from Wrocław seems to stand out as compared with the sculptures in question as regards the destroyed body of Christ, the strong inclination of His torso to the right, the squatted legs and particular sculptural details. The fi gure from the church in Wrocław refers to geometrized forms known from crucifi xi dolorosi of the fi rst half of the fourteenth century; at the same time the softness of the curved torso and the smoothness of the ribs anticipate the emergence of the beau style. The comparison of the crucifi x from the Corpus-Christi church with the selected examples of fourteenth- century Silesian sculptures also excludes formal-stylistic and technical connections. Its ideological meaning is close to the Pietà of Lubiąż (Leubus) and is associated with the specifi c type of devotion – typical of the second part of the thirteenth and the whole fourteenth century – oriented towards considering the Passion of Christ, and towards individual religious experiences. Although individual sculptural details characteristic of the Hospitallers of St. John church can be linked with some other Wrocław crucifi xes, the presentation of the body in such an expressive manner is unmatchable.</p>

The handgrip strength determines the overall physical health and muscle function of the hand. Nowadays in Bangladesh, female laborers are an important source of work force in many industries. Laborers require more handgrip strength to perform their daily work efficiently. Besides, hand is the part of the body that directly related with handgrip strength, so, the hand dimensions are deemed essential to investigate. Therefore this study is to investigate the association of the dominant handgrip strength with the hand dimensions like hand length, hand breadth, hand span, palm length, palm breadth and wrist breadth of adult Bangladeshi female laborers. Hundred (100) adult female laborers aged between 18 to 45 years, residing in different slums in Dhaka city of Bangladesh were the participants of the present research. Six selected hand dimensions of the right side were measured using the digital slide caliper by direct physical procedure and dominant handgrip strength was measured using a digital handgrip dynamometer. The associations of the dominant handgrip strength with the selected six hand dimensions were tested using Pearson’s correlation coefficient test. The mean value of the dominant handgrip strength of the laborers was 25.6 kg. In present research, the dominant handgrip strength was positively associated with the six selected hand dimensions (hand length, hand breadth, hand span, palm length, palm breadth and wrist breadth). However, the association of dominant handgrip strength with the breadth of hand, palm and wrist reached up to significant level individually. Besides, to get desired success in work of a female laborer, it is important to see the hand anthropometry and handgrip strength, because, better handgrip strength lead to better performance in work.

An asymptotic study is made of potential and tree-surface elevation due to forward motion of a submerged body with an oscillating velocity. The latter is supposed to be a short period. As the nondimensional period ε 1, the singular perturbation technique is applied. Using two-term expansion for the potential, the principal terms of asymptotics for instant and mean values of wave resistance are obtained. The mean value (up to a term 0(e)) is the sum of two addends, the first of which is the wave resistance of the same body moving at the mean speed. The second addend is proportional to the dispersion of velocity with the coefficient depending on the form of the body. This coefficient vanishes if the body is symmetric with respect to the mid-section. Numerical examples for the two-dimensional problem show that there exist cylinders with the following property: the absolute value of wave resistance decreases when passing from motion at the mean speed to motion with oscillating velocity.

The aim of the study is to determine the dynamics of morphological changes in the ampullae of the fallopian tubes at different age periods of life using autopsy material from women giving birth. Materials and research methods. The analysis of the results of a complex morphological study of the ampullae of the fallopian tubes of 150 corpses of giving birth women of adolescence, the first and second periods of adulthood, elderly and old age was carried out. Results. The histological picture revealed regular atrophic changes in all layers of the wall of the ampulla of the fallopian tube. When comparing the mean values in five age groups according to the Kruskell-Wallis test, statistically significant differences in the length of the epithelial lining in the transverse section of the ampulla of the right and left fallopian tubes (p < 0,001), as well as the wall thickness of the ampulla of the right and left fallopian tubes (p < 0,001) have been identified. Conclusion. The results of the study supplement the literature data on morphological changes in the fallopian tube and can be used as a standard reference.

1. Pressures on the right and left sides of the tails of swimming bluefish were measured and found to have a range of +5.9 to - 5.9 cm H2O. The pressures were resolved into their forward and lateral vectorial components of force to allow calculation of forward and lateral force and power at speeds ranging from 0.26 to 0.87 m/s. 2. The peak to peak changes in force of acceleration of the body, measured with a forward accelerometer averaged 209 g or 2.05 N at 0.48 m/s, and were compared with the maximum to minimum excursions of forward tail force averaging 201 g or 1.97 N at the same speed. The mean difference was 8 g, s.d. of the mean difference ± 29, s.e. of mean difference ± 10 g. 3. Mean tail thrust was calculated as the time average of tail force in the forward direction. It averaged 65 g, or 0.64 N, at 0.48 m/s. The mean forward power was 0.34 N m/s at 0.48 m/s. The drag of the gauges and wires accounted for 10% of this figure. 4. The mean lateral power of the tail was 1.28 N m/s at a mean speed of 0.48 m/s. 5. The propulsive efficiency of the tail, calculated as the ratio of forward power to forward plus lateral power, was found to be 0.20 s.d. ±0.04, s.e. ±0.01 and was not related to speed. This suggests that 80% of the mechanical power of the tail was wasted. Turbulence in the water may have contributed to this large drag and low tail efficiency.

Abstract: Radioactivity must be studied in soil to see the changes in the doses of human exposure. In this study, natural radioactivity and radiological hazard indices in soil samples of the Faculty of Agriculture (Al-Husseineya site) and the Faculty of Medicine (Al-Mothafeen site) in Kerbala Governorate were determined using gamma-ray spectroscopy. The results showed that the mean values of specific activity (in units of Bq/kg) and standard errors of: 238U, 232Th and 40K at Al-Husseineya site was 21.7±7.2, 9.43±3.2 and 335.8±82.2, respectively, while at Al-Mothafeen site, the mean values and standard errors were 22.4±8.8, 11.2±3.3 and 333.1±70.7, respectively. Radiation maps of natural radioactivity (238U, 232Th and 40K) at Al-Husseineya and Al-Mothafeen sites were mapped using geographic information system (GIS) technology. Moreover, most results in the present study fall within the acceptable levels, as defined by OCDE, UNSCEAR and ICRP. Therefore, there is no significant radiological hazard at the sites which were studied. Keywords: Radiological hazard, Natural radioactivity, Soil, NaI (Tl), Gamma-ray, Karbela University.
