The objective of this study was to evaluate the growth performance and carcass characteristics of crossbred lambs of Dorper sheep crossed with Santa Inês or Brazilian Somali sheep and raised under an intensive production system in the northeastern region of Brazil. A total of ten non-castrated male lambs of each genetic group were used in this trial under a fully randomized design. The lambs were housed and creep fed until weaning at 60 days of age. After weaning, they were sent to a feedlot for finishing with a high energetic diet until slaughter, which occurred when they reached 3. mm of subcutaneous fat thickness. The crossbred Santa Inês lambs exhibited a higher daily gain (0.3. kg/day) than the Brazilian Somali crossbred lambs, which were more precocious in reaching the slaughter fat thickness (118 days). Significant differences were observed between the genetic groups for the hot carcass weight, carcass shrink, and measurements of the rib eye area, the carcass and leg compactness indexes and the weight of the carcass joints. However, no significant differences were found for the amount of lean meat per cold carcass weight unity and the yield of retail cuts. The crossbred Brazilian Somali lambs presented a higher amount of fat per cold carcass weight unity (26. mm/100. kg) than the Santa Inês lambs. According to the results obtained and under the described experimental conditions, it may be concluded that at the same maturity level, the growth performance, the age at slaughter and the main carcass characteristics vary with the genetic group, making possible the use of local sheep breeds to meet efficiently the needs of different markets. © 2013 Elsevier B.V.

Lavender (Lavandula officinalis L.) of Leaves are well known flavoring agent for different kinds of plates. The volatile oil of the leaves is used in the perfume and Medical. Many criteria affect the production of volatile oil and chemical composition of aromatic herbs. Drying is the most usual way to maintain the quality of Medicinal and Aromatic Plants. In order to find the best method for drying of leaves, lavender differing approaches, viz. shade, sun, microwave (100, 180, 300w), and oven drying (50°C and 70°C) were compared. The process of drying was carried on until the sample weight reduced to a moisture content of about 0.10 on a dry weight basis, or 10% on a wet weight basis. The volatile oil content was found for variety from 0.6 to 1.3% under different drying methods. The essential obtained from dried leaves of hydrodistillation was analyzed by GC and GC-MS. The major components of the oils were linalool and linalyl. Regarding the obtained results, drying methods treatments had a significant effect on the Volatile oil content and composition and the highest amounts of Linalool and linalyl were measured as 26.8% and 24.2% in the microwave drying treatments (300w). © 2014 AENSI Publisher All rights reserved.

Nutrients recycle is related to the absorption capacity by different cover crop species. Already speeds of decomposition and of nutrient release of straws produced is mostly related with C/N ratio, with a marked difference between grasses and leguminous. In this sense, the objective of this study was to evaluate the biomass production and macronutrient contents and accumulation, decomposition, and nutrient release from straw of millet (Pennisetum typhoides (Burm.) Stapf) and millet - jack - bean (Canavalia ensiformes (L.) DC.) intercropping, under field conditions, under common bean, sown in August (winter/spring). Decomposition and nutrient release was determined in nylon bags (0.2 × 0.2 m, 1 mm mesh) filled with straw quantities according to the area of the bag. The experimental design was randomized blocks with four replications in split plot arrangement. The straws represented the plots and the subplots evaluation periods (0, 8, 16, 24, 40, 56, and 72 days). The residues were dried to constant weight in a forced-air oven at 65 °C to determine the remaining dry matter, then ground and sent to a laboratory to analyze macronutrient contents. Based on the contents and remaining dry matter amounts, the remaining nutrient amounts were determined, expressed in relation to the initial amount. Non-linear models were fit to the values, choosing the best adjustment in each case. Biomass quantity, N and Ca contents and cycling of nutrient quantities was greatest in the intercropping straw. The decomposition and nutrient release speeds were also highest in millet - jack - bean intercropping straw. Source

One advantage of working remotely, and particularly of working from home, is the ability to bring your personal and professional lives closer together, reducing conflict between different types of obligations. But what if your professional and personal life are a bit too close together – like, for example, your fellow remote worker spouse sitting a few feet away from you all day? Potential problems are, obviously, numerous, as a first person narration of a dual remote worker marriage in Marie Claire illustrates. With sections written by both members of a telecommuting couple, the piece enumerates the many challenges of a spouse joining his or her hubby in home working. Chris Norris, the first member of the couple to go remote, describes what it was like to suddenly have his wife, Ellen Carpenter, around the house after she was laid off and started working freelance. He chooses a frankly homicidal reference: For six months now, my wife and I, both writers, have been working at home together in our one-bedroom apartment. If the precariousness of this situation isn’t obvious, I refer you to the best film ever about shared domestic work space: The Shining. There’s Jack Nicholson’s would-be author, self-exiled in an empty hotel. Typewriter clacking, he squints into the page—limning, seeking, probing, his mind finally edging up against that drifting, vaporous thought, when … “Hi, Hon!” chirps googly-eyed Shelley Duvall. “Get a lot written today?” The ax murders that follow are excessive, I grant you, but incomprehensible? I don’t judge. True, our two-desk living room is no Overlook Hotel — even if it is a feng-shui horror show — and Ellen respects its sanctity. But I do feel like a crucial curtain has been pulled back. In our courtship phase, when she worked at an office, she would often swing by my place after work and find me lounging on the couch in a rumpled Agnès B. shirt (just put on), an open book on the table (unread), and another finished project on the screen. “Yep,” I’d say. “This is where the magic happens.” Now she knows what the magic actually looks like. For her part, Carpenter didn’t suffer from a loss of privacy or murderous hallucinations but from the imposition of domestic expectations on her professional time. The couple set ground rules about interrupting each other when she started working from home, she writes, agreeing that, From 10 to 6, Monday through Friday, we’d be colleagues. But very quickly, I took on other roles as well. Because Chris was used to my only being home in the evenings (making dinner) or on the weekends (making lunch, Swiffering the floor), certain primal, gender-specific assumptions were activated. Coworker? Try personal chef, maid, cheerleader, dog walker, masseuse, and make-out partner — on call, 24/7. In my attempt to adapt to his routine, I unconsciously stepped into some kind of ’50s, June Cleaver stereotype. The first week, I offered to make lunch. The next, I volunteered to read an article he had just finished and to give him feedback prior to its submission — that is, to tell him it’s great. The week after that, I assumed laundry duties. Slowly but surely, all this wrought a learned helplessness I still can’t quite believe. My husband was once a strong, independent man who’d return from a six-mile run with a bouquet of my beloved dahlias. Now he can’t crack open a can of Progresso. By the end of the Marie Claire article, you’re really, really rooting for Carpenter to get another office-based job. Are things always so grim for couples that work from home together? A recent two-part interview of another remote working couple on blog How to Work From Home offers more grounds for hope. Again, the wife, coach Maria Varallo, struggles more to separate the domestic and the professional. “There are times I find it too much being mom and wife whilst being a professional all at once,” she says. But in this case, having a partner working at home seems to have affected the husband in the opposite way it did Norris. Rather than reverting to 1950s-era stereotypes, Varallo’s husband Kris, a database administrator, has actually become more aware of all the effort that goes into running a family. “The great thing about working from home is Kris is far more sensitive to what needs doing. I especially have noticed over the years as my work has grown and become more established how the house becomes very relaxed,” Varallo says. “If I put on the washing in the morning he’ll put it out if I’m out, he is aware and I think that’s because he also works from home.” So how do you get a situation more like Varallo’s and less like Carpenter’s? Steve Cooper, co-founder of Hitched, an online magazine for married couples, recently offered some tips to Forbes. Citing a recent letter his magazine received from a woman with a problem (e.g. husband) much like Carpenter’s as inspiration, Cooper offers these suggestions: Define Your Workspace. Having a space of your own is extremely important, even if one of you has to work from the kitchen table. If possible, set up shop in two separate rooms on opposite sides of your home. Create Office Hours. If you only have one room that can work comfortably as a home office, [owner of The Protocol School of Texas Diane] Gottsman says you might trade use of that room by creating work hours. Communication. Dialogue with each other is paramount. “You have to be able to talk to each other and really be honest without becoming defensive,” says Gottsman. Have a conversation where you explain what you need, when you need it and how these ground rules need to be followed going forward. Dealing with the Family. Your boundaries should be very, very clear. “We want to feel like what we’re doing is of value and that our spouse also values us,” says Gottsman. “It may not seem as important, but if we’re doing it, it is important.” Your family needs to know they cannot walk in to your office and interrupt. Check out the full article for more detailed advice. Author Jenna McCarthy has also offered tips to TheMogulMom, including, “if you have the occasional need to check in with your spouse throughout the day, you can save a ton of time by setting up an IM account.” As well as, “be mysterious…. wives tend to way overshare when it comes to the minutia of their lives. Your dude doesn’t need (or want) to hear a play-by-play of your day.” Though one wonders if husbands are really immune from long-winded explanations of their professional trials and tribulations (personal experiences says no), this last tip makes sense if applied to both genders. Has working at home with your partner changed the gender dynamics between you, i.e. is one person taking on a more or less traditional role around the house?

The concern with the environmental dimension of sustainability has become more and more relevant in studies related to agribusiness. The need of a robust and trusty framework to measure the environmental impacts in the agribusiness activities is being presented as a trend in countries leaders in food production worldwide, like Brazil. In this context, this paper describes a review related to the concept of Life Cycle Assessment - LCA which is being widely recognized and used by technicians and researchers all over the world to the environmental impacts of production chains and allowing various applications on the production systems. The paper was elaborated based on a bibliographical research carried out by accessing national and international publications, websites and proceedings of scientific events. Its main goal is to describe the importance and the diffusion of LCA as a framework to analyse production systems in Brazilian agribusiness. In conclusion, the LCA framework is still not widespread in the Brazilian agribusiness as well as the studies about this subject are still very scarce. Source
