Mango varieties Bengkulu is one of high yielding varieties from Bengkulu Province. The plants grow well and produce fruits almost year-around in all regions in the province of Bengkulu. Mango varieties Bengkulu have very large fruit, thick fruit flesh and slightly sour flavors. It makes Mango varieties Bengkulu is very suitable to be consumed in the form of a processed. Fruit leather is one form of processed fruit. Fruit leather is a thin sheet of fruit in dried form. The results showed that the best processing techniques of fruit leather for mango varieties Bengkulu is the process with addition of sugar by 20% and drying temperature at 60 ?C. The treatment produce fruit leather with the best physical appearance and flavor compared with the other treatments.

Recently, increasing attention has been paid to the application of enzymes in a wide variety of leather production processes. The aim of the present study was to investigate the action of enzymatic pickling on derma’s collagen and the influence of this action on subsequent processes and properties of chromed and finished leather. The application of active in acidic medium proteolytic enzymes in the pickling process led to an additional impact on derma structure: collagen was more strongly affected and the porosity of the pelt dermis was reduced, but the hide became more thermally stable. The enzymatically pickled pelt bonded more chromium and reached higher shrinkage temperature while chroming; dyes penetrated deeper; such leather bonded more fatliquors. On the other hand, the action of enzymes worsened the physical–mechanical properties of the leather, as the experimental leather was weaker than the conventional one. The first was characterised by weaker grain layer and had significantly higher relative elongation. Therefore, as some properties improve and others worsen during such a process, the application of every enzyme should be carefully investigated and optimized to produce a leather with defined properties.

Twenty-three vegetable amaranth genotypes were evaluated for variability, interrelationships among antioxidant leaf pigments and foliage yield. Five genotypes found to be a rich source of antioxidant leaf pigments and might be directly selected as antioxidant leaf pigments enriched high yielding varieties. Two genotypes had high content of antioxidant leaf pigments with low yield might be used as donor parents for antioxidant leaf pigments genes to develop transgressive segregant or pigment enriched transgenic vegetable amaranth varieties. The insignificant negative genotypic correlation was observed between total carotene versus all antioxidant leaf pigments, ascorbic acid versus all antioxidant leaf pigments and foliage yield versus rest of all traits. Improvement of vegetable amaranth regarding carotene and ascorbic acid might be possible without compromising yield loss. On the other hand, most of the interrelationships among antioxidant leaf pigments traits indicated that improving of one antioxidant leaf pigment significantly improved the other antioxidant leaf pigments.


This investigation is a continuation of the word on copper-zinc alloys reported in previous papers. Our previous measurements were made on quenched alloys, and it was assumed that the conditions prevailing at any temperature at the moment of quenching were retained in the quenched samples. In the present word an attempt is made to investigate the validity of this assumption by examining the alloys at the actual temperatures of annealing. Attention is directed mainly to the β-phase in tire pure region and in the mixed regions on either side of the pure phase. It was hoped that such measurements might also throw more light on the nature of the β-transformation. Apparatus and Method of Experiment . The precision camera was the same in principle as that previously used and described, with modifications in deign for high temperature word. It was made entirely of invar except that three silica rods connected the portion of the drum carrying the film to that carrying the sample. By this device the one part was well insulated thermally from the other. In order to take photographs in vacuo , the camera was fitted into a brass box with a removable lid and water-cooled sides; inside the box, the heater, consisting of "Kanthal" resistance wire embedded in alundum cement, was mounted. To hold the sample, which was in the form of fine filings on thin foil, against the camera frame, a thin sheet of copper foil was used. This was anchored with insulating porcelain beads and wire springs to the camera frame carrying the film. To minimize the heat passing from the sample to the camera frame, a thin sheet of mica of definite thickness was used around the slot over which the sample was placed. The sample was heated by bringing the heater, shaped to the contour of the camera frame, into close contact with a similarly shaped copper sheet about 1⋅5 mm. thick, into which the "hot" junction of one thermo-couple was silver-soldered; this in turn pressed against the foil on which the sample was mounted. Leads for the thermo-couple pyrometers—one to measure the approximate temperature of the sample photographed and the other to measure the camera temperature near tire film—passed through insulated plugs in one side of the box. On the opposite side, leads to the heater were similarly inserted. An outlet for exhausting the box completed the construction.

AbstractThis paper considers the figure of the realised or hypothetical effeminised male in Homer's Iliad, and discusses the impact of effeminacy upon idealised masculine identity in the epic. The idea of effeminacy in the Iliad is explored alongside several related but distinct concepts, such as cowardice, childishness, dress, physical appearance and battle-field rebukes and insults. The second half of this paper addresses more specifically the figure of Paris and the comparisons drawn between Paris and his brother Hektor. I argue that actualised or hypothetical effeminacy is constructed in the Iliad in order to define, by contrast, a ‘proper’ masculinity, founded on concepts of martial fortitude and civic responsibility, thoroughly antithetical to the ‘other’ which the effeminised male symbolises.

The principle on which the instrument I am about to describe is constructed, is, that the volume of a given quantity of air under a constant temperature, is inversely as the pressure to which it is subjected ; and the means I employ to estimate the change of volume which that quantity of air undergoes, by being subjected to differences of pressure caused by a change of elevation, are the determination of the difference of weight which a floating body is capable of sustaining in both situations. Thus, if a vessel containing a quantity of air and water be floated in water, and there be a com­munication between the water in the floating body and that in which it floats, it will follow, that when such an apparatus is subjected to diminished pressure, the air within the float will dilate, and cause a volume of water equal in amount to the dilatation of the air to be driven from the float; and the difference of weight which the floating body will sustain, will be the exact weight of the water expelled : if such an appa­ratus is subjected to an increased pressure, the air within it will contract, and consequently a quantity of water, from that in which it floats, will enter the float, and the diminished weight it is capable of sustaining will be the weight of the water which has entered the float, in consequence of the diminution of the volume of the air. It is by such means, with the instrument immediately to be described, and by the help of a very simple calculation, that I propose to determine the difference of level between any two places. Plate X. fig. 1. represents the floating part, made of thin sheet brass, the body of which ( a ), in form the frustum of a cone, is nine inches long, two inches in dia­meter at one end, and one inch at the other, and capable of containing about fourteen cubic inches. In the centre of the widest end, a small stud of brass ( b ) is hard sol­dered, into which a brass wire ( c ) is screwed, an inch and three-eighths long, and about one twenty-fifth or one thirtieth of an inch in diameter : the other end of the wire is screwed into a brass stud in the middle of the convex side of a shallow cup ( d ), made also of brass, and as light as possible, so that it will retain its shape, and be capable of sustaining a weight of about eight hundred or one thousand grains.

Cases of 30 whey protein isolate-sodium caseinate-glycerol composite protein films based on different ingredients and processing techniques, and their packaging properties were analyzed by Q and R cluster analysis, respectively. The results verified that there was a correlation in either 30 cases or 7 indexes of packaging performance, which contributed to a scientific sorting. 30 cases could be divided into 5 groups by Q cluster analysis with the Euclidean distance at 40, in which case 28 and 30 exhibited the highest similarity. On the other hand R cluster analysis in packaging performance indicated that gas permeability and haze values of composite films tended to be more similar than the others.

This paper examines the existence of an unwelcoming or stereotypical culture using evidence on how women and men are portrayed in anonymous discussions on the Economics Job Market Rumors forum (EJMR). I use a Lasso-Logistic model to measure gendered language in EJMR postings, identifying the words that are most strongly associated with discussions about one gender or the other. I find that the words most predictive of a post about a woman are typically about physical appearance or personal information, whereas those most predictive of a post about a man tend to focus on academic or professional characteristics.

Aim: This work gives the reports on experimental study of the effects of drying on some selected vegetables, namely fluted pumpkin (specimen I), spinach (specimen II), lettuce (specimen III), and waterleaf (specimen IV). Methodology: The vegetable specimens were dried at regulated drying temperatures of 323K, 333K, and 343K, and the percentage amount of water, fat, crude fibre, ash, protein, and carbohydrate, as well as the fungi and bacteria counts in the vegetable specimens was determined at these temperatures. Results: The results revealed that the amount of water in the vegetable specimens reached 0% earlier at the regulated drying temperature of 343K than at the other regulated drying temperatures. The results also indicated that the dried vegetable specimen II has highest fat content of 8.2%, the dried vegetable specimen III has highest crude fibre content of 14.5%, the dried vegetable specimen IV has highest ash content of 18.6%, the dried vegetable specimen I has highest protein content of 30.3%, and the dried vegetable s specimen III has highest carbohydrate content of 42.2% at the regulated drying temperature of 323K. The same trend of results was obtained for the regulated drying temperatures of 333K and 343K. Furthermore, the results showed that at the regulated drying temperature of 323K, the dried vegetable specimen III has the lowest bacteria counts of 4.3 x 107 CFU/g. The trend of result obtained for the regulated drying temperatures of 333K and 343K is similar to that of the 323K. At the regulated drying temperature of 323K, the dried vegetable specimen II has the lowest bacteria counts of 1.7 x 107 CFU/g. The same trend of results was obtained for the regulated drying temperatures of 333K and 343K. Conclusions: Drying has effects on the percentage amount of fat, crude fibre, ash, protein, and carbohydrate in the vegetable specimens. The microbial counts and the fungi counts decrease when the temperature increases. The present work can be applied in food engineering industries, and engineering in agriculture.

This research aimed at testing multiple fitness hypothesis of attraction, investigating relationship between male facial characteristic and female students' reported readiness to engage in various social relations. A total of 27 male photos were evaluated on five dimensions on a seven-point Likert-type scale ranging from -3 to 3, by convenient sample of 90 female students of University of Sarajevo. The dimensions were: desirable to date – not desirable to date; desirable to marry – not desirable to marry; desirable to have sex with – not desirable to have sex with; desirable to be a friend – not desirable to be a friend; attractive - not attractive. Facial metric measurements of facial features such as distance between the eyes, smile width and height were performed using AutoCad. The results indicate that only smile width positively correlates with desirability of establishing friendship, whilst none of the other characteristics correlates with any of the other dimensions. This leads to the conclusion that motivation to establish various social relations cannot be reduced to mere physical appearance, mainly facial features, but many other variables yet to be investigated.

To view culture as a multispecies and not as an anthropocentric one is the call of the era. The liberal Humanist idea of human as an autonomous entity is to be debunked, as culture involves not only Homo sapiens, but also other species – animals, plants, microbes, machines and hybrids. No species can dwell independently. Each species thrives in a network, interconnected and interdependent to each other. This network forms a culture of multispecies, where every being is akin to the other. Multispecies culture is all inclusive and all encompassing, disregarding the crippling binaries of human/ non-human, culture/nature, abled/disabled, normal/abnormal and so on. It is important to realize that each binary is an anthropocentric cultural construct. It must be discarded in order to create the culture of companion species, that is includes all forms of existence, not overlooking the ‘unwanted’ object as the minor ‘other’, in the anthropocentric view. The paper aims to argue that each species (highlighting the figure of tree in the paper) is an active actor in the bio cultural space. It strives to emancipate the figure of a tree from the clutch of anthropocentric notion, as ‘nature’/ ‘passive recipient’/ ‘care-giver’/ ‘mother’. To serve my purpose, I have chosen a Science Fiction, titled The Saliva Tree by Brian Aldiss. The fiction has an alien tree, functioning in a farm on the Earth. The tree has a horrendous physical appearance, is carnivorous and is non-sessile. All such features compile to render the arboreal creature as a ‘monster’, an identity imposed upon a misfit, considering it as a threat to the human-centered culture. I have argued how the farm with the ‘monster’ tree and other variety of species and machines becomes an archive, a dynamic biocultural space. It also enhances the botanical culture or ‘FloraCulture’, as termed by John Charles Ryan.
