The use of calorimetry in ecology.

THE USE OF CALORIMETRY IN ECOLOGY. The macroscopic effects caused by sun radiation and the mankind-nature interactions in a ecosystem are firstly presented. However, the impor- tance of calorimetric determinations to clarify some phenomena related to the living microorgan- ism populations and their interactions with the food additive or inhibitor agents are reported. The collect values illustrate the occurence a great deal of effects in this microscopic world. For this subject, the reachest Latosol soil was selected due to the content of organic matter and conse- quently in microorganisms. Microbial activity was stimulated by addition of glucose, which showed to be the best nutrient source. Inhibitory effect was detected with many compounds used in the agriculture like some herbicides and fungicides. Although the assays are based on the use of the microcalorimetry, other techniques like respirometry contributes strongly to the understanding of the ecosystem. The main objective in this exposition is to stimulate by means of many interesting examples, the importance of preserving the environment in order to establish direct analogies by using the Chemistry in the daily life.

Use of acoustic telemetry techniques to understand the individual variability in movement ecology of juvenile lemon sharks, Negaprion brevirostris, in natural conditions, around Bimini Islands, Bahamas: a comparison study with preliminary personality trai

Use of acoustic telemetry techniques to understand the individual variability in movement ecology of juvenile lemon sharks, Negaprion brevirostris, in natural conditions, around Bimini Islands, Bahamas: a comparison study with preliminary personality traits observed in mesocosms

These last observations also underlined the ecological importance of mangroves as a nursery area for juvenile lemon sharks. The deterioration of the conditions on the western side of the NS might impede the future wellbeing of this nursery. Already Jennings et al. (2008) and DiBattista et al. (2011) documented the effect of anthropogenic disturbances on populations of juveniles in the NS and outlined the vulnerability of the area. This concern was strengthened by the case of individual #5667. The home range and core area of this juvenile was established around the area most exposed to the current disturbances. The selection of this location raised two main hypotheses with respect to the early loss of track for this shark. The interruption of emissions in January 2015 from the individual corresponded to an intensification of the anthropogenic disturbances, which started in late November 2015. Constructions and resort development might have resulted either in a pressure leading to the migration of the shark out of its original nursery or to the death of the individual. This shark was last detected on SUR7 (Fig. 21), localized within its main core area, indicating the former prospect was rather unlikely. Moreover, the conclusions reported by Jennings et al. (2008) sustain the likelihood of a premature death of the individual caused by the rapid and intense development around its home range. The authors pointed out the effect of construction developments on the banks of the NS, revealing a decrease in survivorship in juvenile lemon sharks, reporting a 23.5% reduction in first-year survival. This consideration raised concern about the survivorship of future populations of juveniles within this nursery ground. The coming PIT-campaigns might bring interesting results, documenting the current concerns.

Investigating The Use Of Mobile Computing In Zimbabwe Polytechnics Case Of A Polytechnic In Zimbabwe

Zimmerman (1999) in his article titled ―Mobile Computing: Characteristics, Benefits, and the Mobile fra mework‖ defined mobile computing as ―the use of computing devices, which usually interact in some way with a centralised information system while away from the normal fixed workplace‖. He went on to say that, Mobile computing technology enables the mobile person to create, access, process, store and communicate information without being constrained to a single location. It is on the above basis that this researcher views mobile computing as embracing a host of portable technologies the can access internet using wireless fidelity (WIFI). These range from notebook computers to tablets, to smartphones and e-book readers. Such devices have brought about Mobile learning (m-Learning) in Zimbabwe Polytechnics, enabling staff and students to share academic resources, be able to research and develop applications from wherever they are. Zimmerman (1999) went on to identify mobile computing hardware, software and communications in use then. He identified hardware as palmtops, clamshells, handheld Pen Keys, pen slates, and laptops. The characteristics of such devices in terms of screen size was small, processing capability was limited and supported a few mobile applications. Over the years mobile devices have improved in such characteristics to make mobile computing easy, fast and user friendly. Great improvements also came with the associated systems software, with the modern devices now running on Android, Symbian and windows 8 mobile, as compared to then when MS DOS, Windows 3.1, Pen DOS were used. In communications Zimmerman talked of internet speeds in kilobytes per second (Kbps), while today’s communications devices have speeds of gigabytes per second (Gbps

Based on these restrictions, it is now the manufacturer who must decide whether he is able to execute the order (within the deadline ap- pointed and using the available facilities) and what will be the price of the product as dictated by the cost of production. Improv- ing the procedure of production costs estimation should improve the contract negotiations and make them more efficient. On the other hand, estimating the cost of production involves, among others, also the need to determine the type of material and treat- ment.

The Concept of Early Vascular Ageing – An Update in 2015

The Concept of Early Vascular Ageing – An Update in 2015

When should EVA be suspected? One approach is to consider a positive family history of early onset of obesity, hypertension, T2D, and CVD, and to screen relatives. Another approach is simply to use clinical skills and look for general signs of early biological ageing (facial appearance, gait, skin turgor, etc.), as was tested in a Danish study of identical twins which found that older-looking twins (as judged by lay people provided with facial photos) displayed a higher risk-factor burden, shorter telomere length, and a worse prognosis during follow-up. 22 A limitation of this study was

Hydration products of Portland cement pastes, hydrated in water and in the presence of zinc ions were studied comparatively at different ages. Hydration products were studied by X ray diffractions (XRD) and infrared spectroscopy (IR). Although IR is not frequently used in cement chemistry, it evidenced a new phase Ca(Zn(OH) 3 ) 2 . 2H 2 O formed during cement hydration in the presence of zinc. The significant retardation of early cement hydration in the presence of zinc is assessed in detail by differential calorimetry as a complement to the study carried out by IR and XRD, providing evidence that permits to evaluate the kinetic of the early hydration.

Electronic Government In Democratic Public Service In One Door Integrated Permit Handling Services Agency In The City Of Samarinda

Development of information technologies and communication in a public sector have to pay more attention to the complexity in its implementation rather than focusing on best practice and strategies which are universal to prescribe how successfully applied Electronic Government program. As a result of advanced civilization for conducting residents of the state of being high-profile figures in the service in the era of democracy. Due to existence of interaction in the form of consultations will find a pattern, approaches such as what is appropriate to the needs of the community in exercising the functions of participation to the state. Based on the results of research on public services in the context of democratic consultation. Look about how the process of consultation with citizens. At the end result appears that the consultants who holds the project activities which implement electronic government that coupled with the community members who said that if the process of consultation having no democratic value. Certainly, it is negative in the development of democracy in the region licensing office, where community involvement not be used as reference to build an understanding together in achieving common interests in accordance with the concept of new public service. Criticism of the statement above , delivered by George (2002) that the failure of the process of the interaction between citizens with the government is located on the level of bureaucracy that is not acceptable to open direct communication. Given only communication with the use of symbols and an intermediary. Statement above supported by Robbins (2005) that stiff of a bureaucracy that has become part the past, of communications for interaction are the dominant choice for in the success of a form of service.

Factors Affecting The Adoption Of Mhealth In Maternal Health Care In Nakuru Provincial General Hospital

Factors Affecting The Adoption Of Mhealth In Maternal Health Care In Nakuru Provincial General Hospital

Abstract : Access to timely and quality maternal health care remains to be a major development challenge in many developing economies particularly in Kenya. The country’s system of providing maternal health care also continue to be anchored on conventional methods of physical presence of the patient and the doctor in a hospital setup. The country’s ICT and health policies also place very little emphasis on the use of these platforms. This study therefore sought to establish the factors affecting the adoption of mHealth by focusing on maternal health in Nakuru Provincial General Hospital. Objectives of the study were: to determine the extent to knowledge and awareness affects the adoption of mHealth in maternal health care at Nakuru PGH, to identify the government policies affecting the adoption of mHealth in maternal health care at Nakuru PGH, to assess how access to technology affects the adoption of mHealth in maternal healthcare, to establish the effects of ICT infrastructure on the adoption of mHealth in maternal health care and to identify the cost aspects affecting the adoption of mHealth in maternal health care at Nakuru Provincial General Hospital. It is envisaged that the study could provide useful information on the adoption of mHealth in managing maternal health care in Nakuru Provincial Gener al Hospital. Descriptive survey research design will be used where all the medical staff and patients of Nakuru Provincial General Hospital was surveyed. The study population therefore was made up of 24 medical staff and 3460 mothers visiting the antenatal clinic selected using clustered random sampling technique. The main instrument for primary data collection was the questionnaire. Data analysis was then done using both descriptive and inferential statistics. Descriptive statistics to be used include frequency counts, percentages, and measures of central tendency

The Impact of E-Commerce Securi ty, and National Environment  on Consumer adoption of Intern et Banking in Malaysia and  Singapore

The Impact of E-Commerce Securi ty, and National Environment on Consumer adoption of Intern et Banking in Malaysia and Singapore

Relative advantage is defined as the extent to which a person views an innovation as offering an advantage over previous ways of performing the same task (Roger, 1983; Agarwal & Prasad, 1997). Because Internet banking services allow customers to access their banking account from any location 24 hours a day and 7 days a week, it provides an enormous advantage and convenience to users (Tan & Teo, 2000). It also gives customers greater control over managing their finances, as they are able to check their accounts easily. Besides, a customer’s Internet experience, his or her banking needs can affect his adoption. As there are more financial products and services, it is expected that individuals with many financial accounts and who subscribe to many banking services will be more inclined to adopt Internet banking. Tan and Teo (2000) has reported that potential adopters of Internet banking services are likely to own multiple banking accounts and subscribe to various banking services. Rogers argues that potential adapters, who are allowed to experiment with an innovation will feel more comfortable with the innovation and are more likely to adopt it. Thus, if customers have the opportunity to try the innovation, certain fears of the unknown may be minimized. Government policy could also aid or hinder Internet diffusion (Mbarika, 2002). This is consistent with the national systems of innovation theory that posits that government policies may encourage or mandate technology development and adoption (King et. al., 1994; Wolcott et. al., 2001). Tan and Teo (2000) suggest that the greater the extent of government support for Internet commerce, the more likely Internet banking will be adopted, thus, confirming Goh’s (1995) suggestion that governments can play an interventionist and leading role in the diffusion of innovation. Potential users in turn would view new applications such as Internet banking services more favorably and hence be more like to use them. Thus, the second alternative hypothesis is:

The Existence Of Leading Islands Securing And The Border Areas Unitary State Of Indonesia An Analysis In Law Perspective

While the political aspect, the border region is classified as vulnerable to political conflicts with neighboring countries due to the intersection of territorial and jurisdictional boundaries, especially in the segment of border that have not been agreed. The issue of border actually starts to rise along with the emergence of waters and fisheries department in 2000 as it continued to release the border policy through the Decree of President (Perpres) No. 78 of 2005 concern the Management of the Outermost Small Islands. As we know there are 11 (eleven) cases in both borders sea and land, as follow: First, the case of Sipadan and Ligitan islands (two our leading islands) by the International Court has decided to belong to Malaysia since 2002. Secondly, the case of Ambalat as an effort of Malaysia to claim the waters territory called Ambalat block occur vagueness in maritime boundary so that this neighboring country tries to take advantage of this vagueness and at last Indonesia set a new base point from Karang Ungaran, until now negotiation has not been completed. Third, Jemur island in Riau province were ever claimed by Malaysia but actually the island is behind our leading island in the area. Fourth, the hostage of supervisory personnel of marine and fishery resources of our borders by Malaysia in response to the arrest of Malaysian fishermen that entering Indonesian waters illegally. These facts indicate that almost each year occur borderline cases experienced by Indonesia. Certainly, it has been a restriction on the importance of the Indonesia sovereignty as a maritime country to be developed and considered as one of the forms of the sovereignty of the Republic of Indonesia relating to the international sea, archipelagic and deepness waters as well as the air space over the territorial sea, archipelagic waters and inland as well seabed and land including natural resources contained therein. Given the importance of maritime areas handling related to the waters, islands and fisheries, it is necessary for specially the management of area with regard to the coastal areas and small islands which are also regulated in Act No. 1 of 2014 concern the Amendment of Act No. 27 of 2007 concern the Management of Coastal Areas and Small Islands. In the Act is understood that the coastal areas and small islands are vulnerable damaged by the activities of people in the use of resources or due to natural disasters and exploitation, so that the need for security measures in the area.

Analysis Of Lean Accounting JIT And Balance Scorecard In The Companys Lean Manufacturing

Dermerwean, [2007] describes that Lean Accounting refers to attempts to derive monetary management information based on Lean principles. [14]. In Lean manufacturing absolutly need lean accounting as control in the enterprise. According to Aghdaei , [2014] said that Lean accounting is looking forward decreasing the stages in implementation process and omitting the standard prices for achieving real prices and inhibiting expense allotments, whereas lean control operations are still considering measurement of system performance and emphasize on social and behavioral controls[15]. Dermerwean, [2007] also said that Lean refers to the management system of applying Lean principles to operations, and Lean Accounting refers to attempts to derive monetary management information based on Lean principles[14]. Maskell, [2006] give statement that Lean accounting focuses on measuring and understanding the value created for the customers, and uses this information to enhance customer relationships, product design, product pricing, and lean improvement.[16]. Based on statement above lean accounting have some function to improvement all aspect about costumers and product. Management accounting information it provides with use one-touch flow design as lean accounting refer to lean operational principle, lean accounting also has alternative to traditional management system. [14],[17]. In the company has principle of lean thinking to grow their company use lean accounting. Rosa [2012] said that lean accounting is a new accounting approach stemming from the growing interest of companies in embracing the culture of lean thinking. [18] There’re new method to increase a companies. Every companies must to use good method one of such lean accounting to control financial. Womack,[2003] describes that lean accounting, more that a new method, is the adaptation of familiar financial and management accounting methods to the needs of lean organizations, with the aims of : providing information to motivate lean transformation; eliminating waste from the accounting processes while maintaining financial

Trophic ecology and the use of shelters and latrines by the Neotropical otter (Lontra longicaudis) in the Taquari Valley, Southern Brazil

The diet showed a relatively regular pattern throughout the year. The greater variation verified was that related to the consumption of fish of the Loricariidae family, with a 19.7% decrease between summer and winter. However, this group was still the most important throughout the year. Its decreased utilization was compensated by an increased consumption of cichlids and pimelodids. Thus, this data suggests that there should be little influence of seasonality on the Neotropical otter diet, although this hypothesis has not been tested. P ARDINI (1998) and G ORI et al. (2003) also

Strategies and Problems in the Promotion of Taal as a Culture and Religious Destination

Strategies and Problems in the Promotion of Taal as a Culture and Religious Destination

Cultural tourism is the fastest growing segment of the tourism industry because there is a trend toward an increased specialization among tourists. This trend is evident in the rise in the volume of tourists who seek adventure, culture, history, archaeology and interaction with local people. The expectancy-disconfirmation theory provided a conceptual framework for this study. The expectancy-disconfirmation theory holds that consumers first form expectations of products or service performance prior to purchasing or use. Subsequently, purchasing and use convey to the consumer beliefs about the actual or perceived performance of the product(s) or service(s). The consumer then compares the perceived performance to prior expectations.

The comparison of the structure and microhardness of the tool steel C90 and HS 6-5-2 remelted with the electric arc

The samples were remelted on the surface with the electric arc with the use of the FALTIG 315AC/DC apparatus. The single remelting was applied. The treatment parameters were used: amperage of the electric arc I = 100 A, speed of the electrode movement v=200 mm/min. As the plasma formative gas, the argon was used. The treatment has been conducted at the depart- ment of Foundry and Welding of Rzeszow University of Tech- nology. After the remelting, there has been the conventional tempering done 1x1 hour in a temperature of 200°C for the steel C90 and 2x2 hours in the temperature of 560 °C for the steel HS 6- 5-2. Parameters of tempering (temperature, time and multiplicity) of the tested steels were selected according to the standard PN-EN ISO 4957:2002U. The microhardeness measurements were made with the Hanemanna objective mph 100. The load used was 0,064 N, the operating time of the load was 10 s. Metallographic tests were conducted on the optical microscope - Neophot 2 and Tesla BS-340 electronic scanning microscope.

Operating characteristics of turbine mixers based on the analysis of power demand of the mixer’s drive

Rebonding of sand mix is a common practice in foundry engineering. The sand mix contains used sand whose grains are already coated with the rebonding material. Rebonding of the used sand [3,4] involves disintegration of grain agglomerates and uniform distribution of the rebodning agent in the entire volume of the sand mix batch, coating of sand grains with the rebonding agent and activation of thus formed coating. Turbine (rotor) mixers are now in widespread use as they feature high efficiency and short mixing cycles.

Studies on protozoa in ancient remains - A Review

Studies on protozoa in ancient remains - A Review

Studies in ancient remains have provided evidence of endemic malaria in Egypt and Italy (Fig. 3, Table IV), where proximity to river valleys would have resulted in a high risk of acquiring malaria, as river flooding pro- duces perfect breeding sites for mosquitoes. Despite the lack of treatments for malaria and references to disease symptoms in ancient Egyptian texts, some texts do note the presence of mosquitoes and the use of nets to avoid them (Strouhal 1992, Nunn 2001, Herodotus 2008). Symptoms including an enlarged spleen accompanied by fever are mentioned in the Papyrus Ebers (Ebbell 1937), but no clear description of malaria is given. In the vicinity of the Tiber, the discovery of a large Roman children’s cemetery, dating to 430 BC (Soren et al. 1995), suggests that an epidemic outbreak of malaria occurred, as falciparum malaria is known to cause a high rate of premature deliveries in non-immune pregnant women.
