Iran is the greatest pistachio producer in the world. A large quantity of pistachio by-product (at least 150,000 tons in DM) is produced from pistachio dehulling process in Iran, annually. The results of some experiments show this by¬product can be used as a feedstuff for ruminants (Shakeri and Fazaeli, 2005; VAhmani et. al., 2005). However, more information about physical and chemical compositions of this by-product is needed. Pistachio by-product is mainly consists of epicarp, peduncle, leaf and a little amount of mesocarp and kernel. The aim of this study was to determine chemical composition and in situ dry matter disappearance of each part of pistachio by-product (Ohadi variety) after 0, 12 and 24 h incubation in the rumen.

ABSTRACT Currently, there is an awareness that is critical to assess the durability characteristics of concrete with as much attention as the mechanical properties. The durability of concrete structures can often be affected by chemical attacks, jeopardizing its performance and security. When concrete is subjected to high temperature at early ages, many physical and chemical changes in hardened concrete may occur. It iswidely accepted that concrete subjected to these conditions of temperature and exposed to moisture is prone to cracking due to Delayed Ettringite Formation (DEF). This work aims at providing a DEF risk analysis on foundation pile caps at the Metropolitan Region of Recife - PE. Temperature rise measurement was performed in situ at 5 different caps through datalogger and thermocouples equipments. Furthermore, the Duggan test was performed in order to assess the level of expansion of 3 cements studied: X (CP II E 40), Y (CP II F 32) and Z (CP V ARI RS). Simultaneously, the chemical compositions of these cements and their respective clinkers were quantified by analysis of X-ray fluorescence (XRF). The cement X (CP II E 40) showed the chemical characteristics favoring with more intensity DEF and, as a result, higher level of expansion in the test Duggan. It is noteworthy that incorporation of metakaolin (8% and 16%) and silica fume (5% and 10%) showed mitigating potential of expansions. It is important to point out that all factors related to thermal properties and chemical composition of the concrete used in the region converge to a condition of ideal susceptibility for triggering DEF. Therefore, it is essential at least minimum and basic requirements in the design specification in order to avoid high temperatures in the massive concrete elements, preventing them from delayed ettringite formation.

In situ investigation results of aerosol optical properties (absorption and scattering) and chemical composition at an urban background site in Lithuania (Vilnius) are presented. Investigation was performed in May-June 2017 using an aerosol chemical speciation monitor (ACSM), a 7-wavelength Aethalometer and a 3-wavelength integrating Nephelometer. A positive matrix factorisation (PMF) was used for the organic aerosol mass spectra analysis to characterise the sources of ambient organic aerosol (OA). Five OA factors were identified: hydrocarbon-like OA (HOA), biomass-burning OA (BBOA), more and less oxygenated OA (LVOOA and SVOOA, respectively), and local hydrocarbon-like OA (LOA). The average absorption (at 470 nm) and scattering (at 450 nm) coefficients during the entire measurement campaign were 16.59 Mm−1 (standard deviation (SD) = 17.23 Mm−1) and 29.83 Mm−1 (SD = 20.45 Mm−1), respectively. Furthermore, the absorption and scattering Angström exponents (AAE and SAE, respectively) and single-scattering albedo (SSA) were calculated. The average AAE value at 470/660 nm was 0.97 (SD = 0.16) indicating traffic-related black carbon (BCtr) dominance. The average value of SAE (at 450/700 nm) was 1.93 (SD = 0.32) and could be determined by the submicron particle (PM1) dominance versus the supermicron ones (PM > 1 µm). The average value of SSA was 0.62 (SD = 0.13). Several aerosol types showed specific segregation in the SAE versus SSA plot, which underlines different optical properties due to various chemical compositions.

Pistachio (pistachio vera) is from Anacardiaceae family. According to the FAO (2003) report, Iran is the largest pistachio producer in the world (more than 310,000 tons). The most three important exported pistachio nuts of Iran are Ohadi, Akbari and Kaleghuchi (Mohammadi, 2005). About 150,000 tons in DM of pistachio by-product (PB) is produced from dehulling process in Iran, annually. This by-product is mainly consisted of pistachio hulls (PH), and then peduncles, leaves and a little amount of mesocarp and kernels. In this experiment the chemical composition, Total Phenolic Content (TPC) and tannin amount of PB and PH of Ohadi, Kaleghuchi and white varieties were determined; also, In Vitro Dry Matter and Organic Matter Digestibility (IVDMD and IVOMD) were measured.

The objective of this study was to evaluate the efficiency of different types of sealing on the physical losses of dry matter, chemical and fermentation characteristics and in situ digestibility of the dry matter of corn silage stored in the feed out face (ramp) of trench silos. The experimental design used randomized blocks, composed of three treatments, namely: T1 - corn silage preserved with double-sided polyethylene of 110 μm thickness (conventional seal); T2 - corn silage preserved with double-sided polyethylene of 200 μm thickness (double-sided); and T3 - corn silage preserved with oxygen-impermeable film composed of double-sided polyethylene of 80 μm thickness on a translucent vacuum polyamide film of 20 μm thickness (double sealing), with four repetitions each. The use of double-sided polyethylene with 200 μm thickness (double-sided) and oxygen impermeable film composed of double-sided polyethylene and polyamide (double sealing), were effective in preserving the chemical composition, fermentation profile, raw protein composition and fiber quality, in addition, the use of these polymers resulted in greater ruminal digestibility of dry matter and reduced the pH, temperature, temperature gradient and physical losses of corn silage from the feed out face (ramp) of trench silos compared to the conventional sealing.

Interest of consumers to products with improved nutritional value, which contribute to eliminating vitamin deficiency, micro- and macroelements, other essential substances is due to the expansion of knowledge and understanding of biochemical functions of these nutrients. Subject: use of beet syrup and beets in ketchup technology has been substantiated in a work; a comparative analysis of the chemical composition of sugar and beet syrup, tomatoes and beets has been conducted; formulations of ketchups with replacement of sugar for beet syrups and tomatoes for beets have been developed; the advantages of new formulations for human health have been substantiated; sensorial, physical and chemical parameters of finished ketchup have been investigated. Results: beet syrup is an unconventional sugar source. Beet syrup contains 93.5% of dry matter, 47-48% of which of total sugar, the most of which is sucrose. Content of beet syrup sugars has been determined by the method of high-performance liquid chromatography, which is, g/100 g: fructose 13.99; glucose 14.18; sucrose 20.39; maltose 0.20.At a temperature of 20 ºС, beet syrup has a high viscosity that is 29.0 Pa•s, which, when heated, decreases and at a temperature of 60 ºC and is about 2.0 Pa•s. The developed samples had the same thick consistency, sweet-sour taste inherent to the control sample. The content of dry matter in the samples was: №1 29.99 %, №2 31.86 %, control 28.66 %, with a normative value of not less than 25 %. The active acidity of samples № 1 and № 2 was 4.2 and 4.1 respectively, which corresponds to the established norms for ketchup. According to the chemical composition, the sugar content was, g/100 g: in the sample №1 13.7, №2 11.8, control 23.9; protein content in the sample №1 1.2, №2 1.4, in the control 0.9. According to the content of vitamin C and fiber, sample number 2, which contains beets and beet syrup, significantly exceeds the control sample. In addition to reduced sugar content by 42.7% and 50,6%, the salt content was also reduced in the developed samples of ketchup, this being a criterion for healthy food products.

Several experiments have been conducted on the value of rapeseed meal (RSM) for dairy cows (Laarveld et al., 1976). The crude protein (CP) content of RSM is almost high (360-420 g kg-1 of DM) with a good amino acid balance. The in situ degradability of RSM was extensively studied (Kendall et al., 1991). The aim of the present study was to determine the chemical composition, in situ degradable coefficients, and ruminal and post-ruminal dry matter (DM) and CP disappearances of an Iranian variety of rapeseed meal (SLM sp.).

Dry Matter Degradation

Current methods of ruminant ration formulation in Pakistan use foreign-based nutrient availability values. These values may not be optimal for all geographic areas, as variation in environment, agronomic factors, animal species, and diet characteristics may not be considered. The aim of present study was to establish a database of the chemical composition and dry matter degradation parameters of tropical forage commonly fed to ruminants in Pakistan and South Asian countries using Nili-Ravi buffalo and Cholistani cattle at heifer and lactating stages. Six cereal grain and four legume species were grown in 3 locations under standard agronomic conditions and sampled at booting and at 50% flowering stage for cereal and legumes, respectively. Dried and milled feeds were analyzed for chemical composition and in situ dry matter degradation parameters using 1 g samples in bags placed in the rumen of 2 Nili-Ravi buffalo heifers, 2 lactating Nili-Ravi buffaloes, 2 Cholistani heifers, and 2 lactating Cholistani cows. The forage family (cereal vs. legumes), species, and geographic location of growth significantly influenced (P < 0.001) chemical composition and in situ degradation fractions. Animal species and developmental stage showed no effect on degradation fractions (P > 0.05). Legume-by-heifer interactions significantly increased (P < 0.05), and legume-by-lactating cow interaction tended (P = 0.065), to increase the rate of degradation (Kd). The selected forages were degraded to a similar extent independent of animal species or developmental stage, and legumes are degraded at higher rates and to a greater extent than are cereals. A moderately significant relationship between Kd and effective dry matter degradability (DMD) suggests that Kd could be the single most important predictor of forage degradability in the rumen.
