Environmental envelope

This study measured production efficiency considering environmental factors (environmental efficiency) to assess the sustainability of pig farms in the district. This study used the data envelopment analysis (DEA) model with undesirable output (COD emissions) to measure environmental efficiency in pig production.

The jumping plant-louse Triozoida limbata is monophagous on guava (Psidium guajava), inducing leaf galls. Guava is planted today in warmer regions around the world but T. limbata is restricted to Central and South America. Recently, the latter has become a key pest in commercial plantations in Brazil (Pernambuco and São Paulo). Modeling of potential distributions is a good tool for developing control strategies of insect pests. Based on distributional data from the Americas, we created models for the psyllids for the present and future using different scenarios of climate change.

This paper applies a four-stage data envelopment analysis (DEA) approach proposed by Fried et al. (1999) to measure the operational environment-adjusted efficiency of sixty mutual funds in Taiwan from 2006 to 2010. We adopt the approach for adjusting negative output as suggested by Lovell and Pastor (1995). In addition, the truncated regression model is used to estimate effects of environmental variables on input slacks in the second stage. The efficiency of funds initially lightly declined, rapidly rose during the financial crisis of 2008, and then gradually fell again.

In the renewable energy investment market, there are risks such as fossil fuel price fluctuations, environmental risks caused by pollutant emissions, electricity price fluctuations caused by energy policies, and so on, which bring certain difficulties to measure the investment efficiency.

The zona pellucida, a transparent envelope surrounding the mammalian oocyte, consists of three glycoproteins, ZPA, ZPBandZPC, andplays a role in sperm–egg interactions. In bovines, these glycoproteins cannot be separated unless the acidic N-acetyllactosamine regions of the carbohydrate chains are removed by endo-b-Galactosidase digestion. Endo-b-Galactosidase-digestedZPBretains stronger sperm-binding activity than ZPC.

Dengue is a re-emerging viral disease, affecting approx. 100 million individ-uals annually. The monoclonal antibody mAb4E11 neutralizes the four serotypes of the dengue virus, but not other flaviviruses. Its epitope is included within the highly immunogenic domain 3 of the envelope glyco-protein E.

The quality requirements recommended in this report are of such an elementary character that most present-day car-sharing organizations in Sweden already conform with them. One could also employ more stringent quality requirements. This could be done in connection with the establishment of new car-sharing organizations, with the procurement of car-sharing services from organizations providing them, or as a condition to be met by car-sharing organizations for public support to be provided it.

At the ICAO Meeting, the EU successfully warded off the threat. A resolution agreed by the International civil aviation organization (ICAO) allows Europe to continue developing kerosene taxes, emission charges and aviation emission trading. British transport minister Alistair Darling hailed "a very successful result in the face of a very difficult situation" at the end of ICAO's triennial assembly in Montreal. "Attempts to restrict freedom of action...have been averted," he said.

The hatching enzyme of oviparous euteleostean fishes consists of two metalloproteases: high choriolytic enzyme (HCE) and low choriolytic enzyme (LCE). They cooperatively digest the egg envelope (chorion) at the time of embryo hatching. In the present study, we investigated the hatching of embryos of the ovoviviparous black rockfish Sebastes schlegelii.

Papillomaviruses are epitheliotropic non-enveloped double-stranded DNA viruses, whose replication is strictly dependent on the terminally differenti-ating tissue of the epidermis. They induce self-limiting benign tumors of skin and mucosa, which may progress to malignancy (e.g. cervical carci-noma). Prior to entry into basal cells, virions attach to heparan sulfate moieties of the basement membrane.

Entry Identification Detach the category and entry number labels from the entry form generated when you submitted your entry information online. The entry number must be firmly affixed in the upper right corner on the back of all entries which are in envelopes. In clear plastic or transparent envelopes, place two copies of the entire entry form into the envelope. In the case of entries that require DVDs or CDs, affix the label on the container or sleeve. DO NOT affix labels to the actual face of the CD or DVD. Label each component of an Integrated Campaign in a similar...

Pertussis toxin, produced and secreted by the whooping cough agent Bordetella pertussis, is one of the most complex soluble bacterial proteins. It is actively secreted through the B. pertussiscell envelope by the Ptl secretion system, a member of the widespread type IV secretion systems.

Climate change is likely to aid the spread of invasive alien species, further threatening agricultural productivity and food security through spread of weeds, pests, and diseases of crops and livestock. The introduction of new and adaptable exotic species for agriculture and to meet increasing demands for biofuels, mariculture, aquaculture, and reforestation presents a particular challenge.

Building engineering physics emerged during the latter part of the 20th Century, at the interface between three disciplines: building services engineering, applied physics and building construction engineering. Building services engineering is the design of mechanical and electrical systems to maintain internal environmental conditions that enable occupants to be comfortable and achieve their maximum performance potential.
