ENGLISHPati Regency has a great potential production of consuming salt but there is an indication that the existing production of consuming salt is not optimum. The objectives of the research are: 1) to analyze the potential production of consuming salt in the study area; and 2) to analyze the existing production of consuming salt in the study area. The research uses descriptive approach. The data consist of primary data and secondary ones. Data collecting uses techniques of interview, field-events and document observation. The analysis uses descriptive one. There are three main findings in the research. Firstly, the potential production of consuming salt in Pati Regency is nearly 209,202 tons yearly but the existing production of consuming salt is 73,380 tons yearly, which is equal to 35.076% from the provided local potential production of consuming salt. Secondly, normatively local community in Pati Regency has consumption to salt 6,674 ton yearly, and the ekspor potential of salt is 202,527 ton yearly but the approximately annual salt ekspor is 66,706 ton because the realized production is not optimum. Thirdly, the product quality of consuming salt in the study area is under standard in general because of under standard raw materials and under standard equipments for production. INDONESIAKabupaten Pati memiliki potensi produksi garam sangat besar tetapi ada indikasi realisasi produksi garam konsumsi belum optimal.

Abstract The soil production attributes of historical agrarian terraced fields were examined in the Budina cadastral area of the Ostrozky Mountains. This landscape represents a unique sub-mountainous Carpathian landscape with farms that use a historically preserved triple-field agricultural system. We determined the geo-spatial parameters of different types of land cover and terraces using geographic information systems. The soil depth was measured in the field, and the skeleton content was determined in the laboratory. We compared data regarding the potential production capabilities of the soil with data from the national classification of agricultural soils. Our results indicated that the soil productivity attributes improved because the naturally less fertile cambisols were positively affected by terracing and long-term cultivation. We recommend the preservation of traditional agricultural activities in historical terraced fields because these terraces represent valuable features that improve the quality of the landscape.

Abstract Huanglongbing (HLB) is considered one of the main citrus diseases; it spreads quickly through orchards, reducing the production and quality of the fruit of affected plants, and causes significant economic losses. In this context, the aim of this study was to estimate the incidence and economic impact of the losses generated by HLB in the micro-region of Paranavaí, in the state of Paraná, Brazil. We used data from the Paraná Agribusiness Defense Agency, which conducts surveys of host plants of the causal agent of HLB. The production sacrificed by HLB was estimated considering the following scenarios: (i) losses occurring from January 2011 to June 2013; and (ii) losses related to the potential production of the citrus plant over its useful life. Although the annual incidence of HLB in the Paranavaí region is currently below 2.5%, there was a 6-fold increase in the incidence of the disease, from 0.16% to 0.96%, in the period considered. Orchards that had lesser than 10,000 plants showed a higher incidence of the disease. The losses produced by HLB generated estimated economic impacts of US$11.8 million and US$39.2 million for the first and second scenarios, respectively. These results highlight the importance of the prevention and management of this disease.

During the past investigations of immunoferritin localization of intracellular antigens in ultrathin frozen sections, we found that the degree of negative staining required to delineate u1trastructural details was often too dense for the recognition of ferritin particles. The quality of positive staining of ultrathin frozen sections, on the other hand, has generally been far inferior to that attainable in conventional plastic embedded sections, particularly in the definition of membranes. As we discussed before, a main cause of this difficulty seemed to be the vulnerability of frozen sections to the damaging effects of air-water surface tension at the time of drying of the sections.Indeed, we found that the quality of positive staining is greatly improved when positively stained frozen sections are protected against the effects of surface tension by embedding them in thin layers of mechanically stable materials at the time of drying (unpublished).

Most production electron beam lithography systems can pattern minimum features a few tenths of a micron across. Linewidth in these systems is usually limited by the quality of the exposing beam and by electron scattering in the resist and substrate. By using a smaller spot along with exposure techniques that minimize scattering and its effects, laboratory e-beam lithography systems can now make features hundredths of a micron wide on standard substrate material. This talk will outline sane of these high- resolution e-beam lithography techniques.We first consider parameters of the exposure process that limit resolution in organic resists. For concreteness suppose that we have a “positive” resist in which exposing electrons break bonds in the resist molecules thus increasing the exposed resist's solubility in a developer. Ihe attainable resolution is obviously limited by the overall width of the exposing beam, but the spatial distribution of the beam intensity, the beam “profile” , also contributes to the resolution. Depending on the local electron dose, more or less resist bonds are broken resulting in slower or faster dissolution in the developer.

Introduction In electron microscopic investigations of crystalline specimens the direct observation of the electron diffraction pattern gives additional information about the specimen. The quality of this information depends on the quality of the crystals or the crystal area contributing to the diffraction pattern. By selected area diffraction in a conventional electron microscope, specimen areas as small as 1 µ in diameter can be investigated. It is well known that crystal areas of that size which must be thin enough (in the order of 1000 Å) for electron microscopic investigations are normally somewhat distorted by bending, or they are not homogeneous. Furthermore, the crystal surface is not well defined over such a large area. These are facts which cause reduction of information in the diffraction pattern. The intensity of a diffraction spot, for example, depends on the crystal thickness. If the thickness is not uniform over the investigated area, one observes an averaged intensity, so that the intensity distribution in the diffraction pattern cannot be used for an analysis unless additional information is available.

In the observation of a thick specimen by means of a transmission electron microscope, the intensity of electrons passing through the objective lens aperture is greatly reduced. So that the image is almost invisible. In addition to this fact, it have been reported that a chromatic aberration causes the deterioration of the image contrast rather than that of the resolution. The scanning electron microscope is, however, capable of electrically amplifying the signal of the decreasing intensity, and also free from a chromatic aberration so that the deterioration of the image contrast due to the aberration can be prevented. The electrical improvement of the image quality can be carried out by using the fascionating features of the SEM, that is, the amplification of a weak in-put signal forming the image and the descriminating action of the heigh level signal of the background. This paper reports some of the experimental results about the thickness dependence of the observability and quality of the image in the case of the transmission SEM.
