    Opis:
    The accepted advice when establishing a plantation of Tuber aestivum syn. uncinatum is that young inoculated trees should be planted on calcareous soils with a naturally high pH level. When a site is employed that has a naturally low pH level, lime is often applied to raise the pH to a considered ideal level of c.7.5. However, this may not be the correct approach. Here we present data from 33 data points taken from commercial truffle orchards in England, UK. Soil pH is correlated to Tuber aestivum syn. uncinatum mycorrhiza survivorship and development. The optimal observed pH was 7.51 but the actual optimal pH for cultivation may be higher. Sub optimal pH levels lead to a reduction of Tuber aestivum syn. uncinatum mycorrhiza. This reduction is not permanent and mycorrhization levels may be improved within a 12 month period by amending the soil pH. The importance of understanding the interaction of pH with other variables and the results in relation truffle cultivation are discussed.

    Opis:
    Tuber melanosporum is the most valuable of all cultivatable truffle species. Farming of this species spans every continent with the exception of Antarctica. Tuber aestivum (syn. T. uncinatum) and Tuber brumale are truffle species that have similar host plant preference and a similar affinity for calcareous soils as T. melanosporum, but occur over a broader geographic zone. The geographic limit of T. melanosporum is thought to be climatically dictated but it is not known whether this is due to an impact on mycorrhizal survival or climatically-derived fruiting triggers. Here, data is compiled from five cultivated research sites in the climatically sub-optimal conditions of the UK in order to address this question. Here we show: (i) Tuber melanosporum mycorrhiza can survive and grow in sub-optimal climatic conditions. (ii) It is climatically-derived fruiting triggers and not ectomycorrhiza survival that dictate the climatic preferences and geographic spread of T. melanosporum. (iii) Important climatic parameters for potential fruiting triggers are sunshine hours, summer rainfall and summer temperatures. The data presented here not only aid our understanding of the ecological parameters of T. melanosporum but also have a practical application for truffle cultivators in choosing suitable locations for a plantation.

    Decision making process in current tactical C2 systems is base on planning process of commanders and their staff. Improving tactical decision making by interfacing war game simulations with tactical C2 systems is achievable. Commander can review the results of the simulation and subsequently modify the tactical plan. Previously, the use of "training" simulations was not a viable solution to real world decision making due to the lengthy time required to input all of the combat entities, the unit organizations and personnel dispositions, the equipment configurations, status of the units and equipment, and the distribution of the available supplies. Modern C2 systems have all of this information stored in the common system databases, and this information can be used to instantiate and populate the simulation through an electronic adaptation of the data structures to match the requirements of the constructive simulation. This paper will provide description of system approach of interfacing simulation and C2 system to improve decision-making.

    Opis:
    Stored-product entomologists have a variety of new monitoring, decision-making, biological, chemical, and physical pest management tools available to them. Two types of stored-product insect populations are of interest: insects of immediate economic importance infesting commodities, and insects that live in food residues in equipment and facilities. The sampling and control methods change as grain and grain products move from field to consumer. There are also some changes in the major insect pest species to take into consideration. In this review, we list the primary insect pests at each point of the marketing system, and indicate which sampling methods and control strategies are most appropriate. Economic thresholds for insect infestation levels developed for raw commodity storage, processing plants, and retail business allow sampling-based pest management to be done before insect infestations cause economic injury. Taking enough samples to have a representative sample (20-30 samples) will generally provide enough information to classify a population as above or below an economic threshold.

    Opis:
    Improved Human Resources Performance can be realized in the employee’s absence. The sophistication of technology to accommodate the absence is the use of a Mobile-Based Attendance Application. Attendance can be used to measure employee performance. One of the measuring tools in measuring performance is the Key Performance Indicator (KPI). KPI values can be obtained from the Mobile-based Attendance Application, as currently implemented by an IT Company. But in its development, there is a shortage on the application features of Daily Attendance, Leave, Report Recaps Attendance and Report Recaps Leave. The value engineering method with the Analytical Hierarchy Process is used in this paper to obtain prioritized alternatives in the development of application feature updates. The results of the research show that the alternative with the largest percentage is owned by Alternative IV (45.6%). These results indicate that this alternative can be used as a recommendation for renewal of attendance application features on IT Company. Alternative IV shows optimal results such as the realization of application feature requirements for users, consumption of fewer workdays for 1-2 days, low costs, easy-to-understand feature design, and uncomplicated programming techniques.

    Africa is a diverse continent composed of many different terrestrial biomes, from the largest nonpolar desert in the world to equatorial forests and Southern African Fynbos. Biodiversity within the continent is high but much remains to be discovered. Sightings of hypogeous fruiting bodies of mycorrhizal fungi (truffles and truffle-like fungi) have been recorded from the most northern countries of the continent to the most southern countries; they have been widely collected for culinary and medicinal purposes. In this review, we describe the most prominent species of mycorrhizal fungi forming hypogeal fruiting bodies, across six genera. The most ubiquitous of these are the “desert truffle” species and the most common genus of plants with which they associate are those of the genus Helianthemum. We also describe the key species of truffle and truffle-like fungi in continental Africa. Where information exists, we describe the ecology, medicinal properties, and ethnomycology of the identified fungi.

    Background: Ovarian cancer is the fifth most common form of cancer in the world and is often asymptomatic in its early stages. Development of ovarian cancer-specific biomarkers for the early detection of disease could improve the current dismal survival rate. Evaluation of serum carbohydrate antigen 125 (CA125), alkaline phosphatase (ALP) and oxidative stress in ovarian carcinoma patients may improve the prognosis of the disease through earlier detection. Aim of the study: The aim of this study was to find the relative risk of ovarian cancer in patients screened for CA125, ALP, Nitric oxide (NO) and Malondialdehyde (MDA) as a marker for lipid peroxidation. Material and methods: 451 subjects with ovarian cancer were screened for serum CA125 levels using a chemiluminescence analyser, out of which 164 showed values above 21 U/ml. 80 subjects with higher values were further analysed for MDA and NO using spectrophotometry and AL P by fully automated chemistry analyser. Results: The selected 80 subjects with CA125 values above 74 U/ml had increased ALP, NO and MDA, also showing positive correlation amongst these parameters. Conclusions: Benefits of CA125 screening vary with age group according to blood CA125 levels. Enzyme ALP levels are elevated with higher values of CA125. MDA and NO indicate oxidative stress and increase as the ovarian marker values increase. Positive correlation amongst the parameters indicates a significant increase in oxidative stress in ovarian cancer. For women with various CA125 levels in different age groups, screening and treatment depends upon individual decision and clinical examination.

    Opis:
    Introduction. The airborne transmission of infectious diseases in livestock production is increasingly receiving research attention. Reliable techniques of air sampling are crucial to underpin the findings of such studies. This study evaluated the physical and biological efficiencies and detection limits of four samplers (Andersen 6-stage impactor, all-glass impinger “AGI-30”, OMNI-3000 and MD8 with gelatin filter) for collecting aerosols of infectious bursal disease virus (IBDV). Materials and Method. IBDV aerosols mixed with a physical tracer (uranine) were generated in an isolator, and then collected by the bioaerosol samplers. Samplers’ physical and biological efficiencies were derived based on the tracer concentration and the virus/tracer ratio, respectively. Detection limits for the samplers were estimated with the obtained efficiency data. Results. Physical efficiencies of the AGI-30 (96%) and the MD8 (100%) were significantly higher than that of the OMNI-3000 (60%). Biological efficiency of the OMNI-3000 (23%) was significantly lower than 100% (P < 0.01), indicating inactivation of airborne virus during sampling. The AGI-30, the Andersen impactor and the MD8 did not significantly inactivate virus during sampling. The 2-min detection limits of the samplers on airborne IBDV were 4.1 log10 50% egg infective dose (EID50) m-3 for the Andersen impactor, 3.3 log10 EID50 m-3 for the AGI-30, 2.5 log10 EID50 m-3 for the OMNI-3000, and 2.9 log10 EID50 m-3 for the MD8. The mean half-life of IBDV aerosolized at 20 °C and 70% was 11.9 min. Conclusion. Efficiencies of different samplers vary. Despite its relatively low sampling efficiency, the OMNI-3000 is suitable for use in environments with low viral concentrations because its high flow rate gives a low detection limit. With the 4 samplers investigated, negative air samples cannot guarantee virus-free aerial environments, which means that transmission of infectious agents between farms may still occur even when no virus has been detected.
