Sari – Pembuatan peta geomorfologi, khususnya bagi mahasiswa geologi pemeta tugas akhir, dan umumnya bagi para ahli Geologi, kadang-kadang menimbulkan kesulitan pada tahap klasifikasi dan penamaan satuan geomorfologinya. Klasifikasi bentuk muka bumi ini dibuat untuk menjembatani kesulitan tersebut dengan tetap mendasarkan pada penjelasan genetis geologis. Dalam pembagian ini terdapat sembilan satuan bentang alam yang dikontrol baik oleh proses endogen maupun proses eksogen, yang masing-masing terbagi ke dalam beberapa satuan bentuk muka bumi. Kesembilan satuan bentang alam tersebut adalah: 1. Pegunungan Lipatan, 2. Pegunungan Plateau/Lapisan Datar, 3. Pegunungan Sesar, 4. Pegunungan Gunungapi, 5. Karst, 6. Sungai dan Danau, 7. Pantai, Delta dan Laut, 8. Gurun, 9. Glasial.Abstract – The development of geomorphologic map, especially for the students of geology, and also for geologists, faces a major problem in the stage of classifying and naming of its geomorphologic unit. This classification of landform tries to act as a bridge the problem which is still based on geologically genetic explanation. This classification is divided into nine landscape units that controlled by endogenic and/or exogenic processes, and each landscape is divided into several landform units. The landscape units are 1. Folded Mountain, 2. Plateau/Horizontal Layer Mountain, 3. Faulted or Block Mountain, 4. Volcanoes, 5. Karst, 6. River/Fluvial and Lake/Lacustrin, 7. Coastal, Delta and Marine, 8. Desert, 9. Glaciated Region.

Detailed soil survey was carried out to characterize and classify the soils of Madahalli watershed, Chamrajanagar district, Karnataka using cadastral map overlaid on Cartosat-1(ortho corrected) image as a base. Three landform units were identified based on elevation and slope i.e. gently sloping lands (3-5%), very gently sloping lands (1-3%) and nearly level lands (0-1%) and mapped into 6 soil series and 30 phases of soil series. These soils were classified as Alfisols (Typic Rhodustalfs, Rhodic Paleustalfs) and Inceptisols (Typic Haplustepts). Alfisols are slightly deep to deep, dark reddish brown to strong brown in hue 2.5YR 3/4 to 2.5YR 4/6, sandy loam to sandy clay in texture with >35 per cent gravel. Inceptisols are very deep, yellowish brown to dark brown with hue 10YR 4/6 to 10YR 3/3, sandy clay loam to clay in texture. These soils are moderately acidic to moderately alkaline (pH 5.26 to 8.17). The organic carbon content varied from low to high (0.21 to 1.16%) and CEC of the soils ranged from 4.1 to 19.9 cmol (p+) kg-1.

Good Agreement

For years the separation of carcinoma and sarcoma and the subclassification of sarcomas has been based on the appearance of the tumor cells and their microscopic growth pattern and information derived from certain histochemical and special stains. Although this method of study has produced good agreement among pathologists in the separation of carcinoma from sarcoma, it has given less uniform results in the subclassification of sarcomas. There remain examples of neoplasms of different histogenesis, the classification of which is questionable because of similar cytologic and growth patterns at the light microscopic level; i.e. amelanotic melanoma versus carcinoma and occasionally sarcoma, sarcomas with an epithelial pattern of growth simulating carcinoma, histologically similar mesenchymal tumors of different histogenesis (histiocytoma versus rhabdomyosarcoma, lytic osteogenic sarcoma versus rhabdomyosarcoma), and myxomatous mesenchymal tumors of diverse histogenesis (myxoid rhabdo and liposarcomas, cardiac myxoma, myxoid neurofibroma, etc.)

Degree Of Differentiation

With the extensive industrial use of asbestos in this century and the long latent period (20-50 years) between exposure and tumor presentation, the incidence of malignant mesothelioma is now increasing. Thus, surgical pathologists are more frequently faced with the dilemma of differentiating mesothelioma from metastatic adenocarcinoma and spindle-cell sarcoma involving serosal surfaces. Electron microscopy is amodality useful in clarifying this problem.In utilizing ultrastructural features in the diagnosis of mesothelioma, it is essential to appreciate that the classification of this tumor reflects a variety of morphologic forms of differing biologic behavior (Table 1). Furthermore, with the variable histology and degree of differentiation in mesotheliomas it might be expected that the ultrastructure of such tumors also reflects a range of cytological features. Such is the case.

Introduction: The analysis and interpretation of electron micrographs of cells and tissues, often requires the accurate extraction of structural networks, which either provide immediate 2D or 3D information, or from which the desired information can be inferred. The images of these structures contain lines and/or curves whose orientation, lengths, and intersections characterize the overall network.Some examples exist of studies that have been done in the analysis of networks of natural structures. In, Sebok and Roemer determine the complexity of nerve structures in an EM formed slide. Here the number of nodes that exist in the image describes how dense nerve fibers are in a particular region of the skin. Hildith proposes a network structural analysis algorithm for the automatic classification of chromosome spreads (type, relative size and orientation).

Increased Susceptibility

Keratitis and conjunctivitis (infections of the cornea or conjunctiva) are ocular infections caused by various bacteria, fungi, viruses or parasites; bacteria, however, are usually prominent. Systemic conditions such as alcoholism, diabetes, debilitating disease, AIDS and immunosuppressive therapy can lead to increased susceptibility but trauma and contact lens use are very important factors. Gram-negative bacteria are most frequently cultured in these situations and Pseudomonas aeruginosa is most usually isolated from culture-positive ulcers of patients using contact lenses. Smears for staining can be obtained with a special swab or spatula and Gram staining frequently guides choice of a therapeutic rinse prior to the report of the culture results upon which specific antibiotic therapy is based. In some cases staining of the direct smear may be diagnostic in situations where the culture will not grow. In these cases different types of stains occasionally assist in guiding therapy.

Organelle Morphology

Adenoaas of the pituitary are no longer classified based on their tinctorial affinity to dyes. With the advent of the newer methods of sophisticated technology, it is now possible to classify. These depending upon the type of hormone secreted based either on histochemical techniques or on ultrastructural characteristics. The latter provides an insight into the cytoplasmic organelle morphology which offers a delightful feast to the eye as well.This paper presents the ultrastructural characters of the pituitary adenoma as seen in Madras. 171 adenomas (124 males and 47 females) were seen during 1972-1989, classified at the light microscope level as 159 chromophobe, 2 basophilic, 4 eosinophilic and 6 mixed adenomas.Ultrastructural examination showed that the sparsely granular prolactin cell adenoma is the commonest adenoma to be encountered closely followed by the growth hormone cell adenoma, null cell adenoma, the mixed cell adenoma and others.

Multichannel ABR recordings for 30 otoneurologic patients were reviewed independently by three audiologists to assess interjudge consistency in determining absolute latencies and overall interpretation of ABR results. Four months later, the tracings were reviewed a second time to evaluate intrajudge consistency in interpretation of ABR waveforms. Interjudge agreement in marking latencies for waves I, III, and V within 0.2 ms was on the order of 90% or better. Intrajudge consistency was slightly higher. Only rarely did inter- or intrajudge differences in latency measurements exceed 0.3 ms. Agreement in overall interpretation of ABR results as "normal" or "abnormal" was unanimous for 90% of the patients. Across pairs of judges, the agreement for "normal" and "abnormal" classification of the ABR tracings was 97%. Intrajudge consistency for "normal" and "abnormal" categorization of the ABR results was 100% for one judge, 97% for the other two judges.

Purpose To better enable communication among researchers, clinicians, and caregivers, we aimed to assess how untrained listeners classify early infant vocalization types in comparison to terms currently used by researchers and clinicians. Method Listeners were caregivers with no prior formal education in speech and language development. A 1st group of listeners reported on clinician/researcher-classified vowel, squeal, growl, raspberry, whisper, laugh, and cry vocalizations obtained from archived video/audio recordings of 10 infants from 4 through 12 months of age. A list of commonly used terms was generated based on listener responses and the standard research terminology. A 2nd group of listeners was presented with the same vocalizations and asked to select terms from the list that they thought best described the sounds. Results Classifications of the vocalizations by listeners largely overlapped with published categorical descriptors and yielded additional insight into alternate terms commonly used. The biggest discrepancies were found for the vowel category. Conclusion Prior research has shown that caregivers are accurate in identifying canonical babbling, a major prelinguistic vocalization milestone occurring at about 6–7 months of age. This indicates that caregivers are also well attuned to even earlier emerging vocalization types. This supports the value of continuing basic and clinical research on the vocal types infants produce in the 1st months of life and on their potential diagnostic utility, and may also help improve communication between speech-language pathologists and families.
