The aim of this investigation was to develop a treatment for combined porcine blood corpuscle concentrate (BCC) and porcine collagenous connective tissue (rind) so as to make more use of these slaughter by-products as an ingredient in a high-quality product such as salami-type sausage. For this study, BCC was preserved, standardized (sBCC) (15% NaCl and 25% protein content), and then added (proportion of sBCC to rind, 15:85) to rind subjected to different treatments designated A, B, and C (A, 2 h at 90°C; B, 5 min at 90°C; and C, 2 h at 3°C). One half of each mixture was again heated (designated A1, B1, and C1; F70, ∼15), and the other half was only cooled (designated A2, B2, and C2). The now colored, highly proteinaceous rind mixtures (A1 to C2) were then cooled and granulated (designated GBR-A1 to GBR-C2). Three of the granulates (GBRA1, -B1, and -B2) proved to be promising new raw materials: their aerobic plate counts were <log 4.0 CFU/g, and their color was appealing (L* values, 23.9 to 25.9; a* values, 17.7 to 22.2; b* values, 11.5 to 12.7). These granulates were then substituted for part (5%) of the meat in the production of fermented raw salami-type sausages. Two of the sausages (SA1 and SB1) were microbiologically stable (containing mainly lactobacilli) and had positive sensory, chemical, and physical properties (e.g., protein, 21%; water activity, 0.90; pH, between 5.3 and 5.4 on day 36) meeting all standards for commercially produced raw sausages. Our investigation yielded a practicable way to treat and combine two slaughter by-products for use in a high-quality meat product.

Blade Production

Antigua has substantially more preceramic sites than any other island in the Lesser Antilles. Archaic peoples made extensive use of the high-quality flint that is common on Antigua to produce industries dominated by unretouched flakes and blades. Analysis of the largest excavated Archaic assemblage from the island reveals that flaked-stone technology centered around the production of direct-percussion blades, and that the majority of other flake classes are by-products of blade production. The assemblage's five major morphological classes of blades appear to represent successive stages of core reduction.

Abstract At present, modern high-yielding crosses of broiler chickens are used to produce high-quality meat with high technological and consumer properties. To assess the meat productivity of broiler chickens grown on fodder produced in the conditions of the poultry factory at our own feed factory, a control slaughter was carried out at the age of 42 days. Analysis of the data obtained shows that with an average poultry live weight of 2000 ± 50 g, the slaughter yield of broiler chickens was 71.8 ± 0.13%. At the control slaughter, we found that the weight of the gutted carcass was 75.23%, offal 10.32%, and technical waste 14.45% (Figure 1).When studying the quantitative and qualitative composition of by-products, we found that liver accounted for 18.42%, stomachs 7.47%, heart 3.39%, neck 12.59%, legs 33.9%, heads 24.23 % by weight of offal.In the structure of technical waste feather is 24.92%, blood is 32.87%, intestine is 42.21% (Figure 3).Thus, the results of our research show that when cutting broiler chickens grown on self-made feeds under the conditions of modern poultry enterprises with a closed production cycle, gutted carcass weight is 75.23%, while legs and heads constitute the main bulk of the mass of by-products.

Abstract Developed procedures to deposit narrow (<100nm), closely spaced, low resistance conductors which exhibit good electrical isolation are demonstrated. The process parameters which limit how narrow a line can be deposited and the methods used to work-around these are discussed. For these depositions, 3pA ion beam current was used with a Mo(CO)6 precursor chemistry. The deposition method minimized the incorporation of non-conductive precursor by-products. To isolate adjacent conductors, a copper etch Credence FIB chemistry was used. The advantages of this procedure over the common practice when XeF2 chemistry is used is also discussed and demonstrated.

Deposition Conditions

High quality, uniform PbZrxTi1-xO3(PZT) films were prepared on the 4 inch wafers by chemical solution deposition (CSD) of 1,3-propanediol precursors. Film uniformity was studied as a function of deposition conditions including spinning rates and co-solvents. Measurements of the surface tension and composition evolution during evaporation and spinning stages showed that the surface tension increases significantly when the co-solvent is nearly completely evaporated. The evaporation of the propanol co-solvent and volatile by-products occurs within the first 5 s of spinning giving rise to defects, whereas octanol is slowly evaporated during 60 s producing uniform coatings. Other co-solvents such as hexanol and pentanol produced uniform films as well. Therefore stabilization of the surface tension in the initial spinning stage is a key to prevent the defect formation. These findings facilitate the deposition of uniform PZT films over large substrates by a simple, scalable, and cost-effective process.

Digestibility data are presented for a more limited range of samples of ryegrass seed, ryegrass seed cleanings and, for comparative purposes, of certain by-products of the milling of oats.3. Ground high quality perennial ryegrass seed has a chemical composition and digestibility comparable with that of oats.4. Ground rough (i.e. uncleaned) perennial ryegrass seed has a chemical composition and digestibility such that its starch equivalent is 90–95 % of that of oats.5. Ground bulked ryegrass seed cleanings has a starch equivalent of about four-fifths that of oats and is comparable in feeding value with better grades of oat feed, i.e. those containing not more than about 20 % of fibre.

Insects are able to convert organic material (i.e. waste and by products) into high-quality biomass, which can be processed into animal feed. Several studies have investigated the influence of growing substrates on the nutritional value of different insect species, particularly black soldier fly larvae and prepupae. This article reviews studies on how insects bioconvert different substrates, the effect of the substrate on the composition of insect meals, and on the development time (time needed to reach the harvesting state). All these studies indicate that insects convert low and high quality organic material (i.e. waste, by products, compound feeds) into high-quality insect biomass. The role and effects of selected nutrients, such as ether extract/fats, carbohydrates and fibre in the substrate, seem to be key factors in defining the features of the biomass as well as the time needed to reach the harvesting state.
