Pengaruh kapur, kompos, N, P, dan K terhadap tanaman sawi
No full textEfisiensi penyerapan unsur hara dipengaruhi dari beberapa kondisi lahan pada umumnya dan kondisi tanah pada khususnya. Derajat kemasaman dapat digunakan sebagai indikator kesuburan kimia tanah karena dapat mencerminkan ketersediaan hara dalam tanah. Pengaplikasian kapur pada tanah menetralisir kemasaman tanah namun tidak menunjang suatu tanah yang bersifat masam dapat menyediakan hara pada tanaman tanpa ada dosis pengapuran maupun input pupuk yang tepat. Untuk mengetahui secara langsung adanya pengaruh kapur, kompos, maupun pupuk penyedia unsur N, P, dan K dibutuhkan tanaman indikator yaitu tanaman sawi. Penelitian ini dilaksanakan pada bulan Juni 2014 ??? Desember 2014 di Desa Tanahkaraeng, Kecamatan Manuju, Kabupaten Gowa dan analisis sifat kimia tanah dilaksanakan di laboratorium kimia dan kesuburan tanah, Jurusan Ilmu Tanah, Fakultas Pertanian, Universitas Hasanuddin, Makassar. Penelitian ini menggunakan metode perlakuan minus one test dengan menggunakan komponen kapur, kompos, N, P, dan K. Susunan perlakuan menggunakan Rancangan Acak Kelompok dengan 7 perlakuan dan 3 ulangan. Hasil penelitian P1 dengan rata-rata berat kering bagian atas (17.96 gr), P2 dengan berat (19.50 gr), P3 dengan berat (20.33 gr), P4 dengan berat (20.56 gr), P5 dengan berat (20.93 gr), P6 dengan berat (25.10 gr), dan P7 sebagai control dengan berat rata-rata (29.03 gr). Penelitian ini memberikan respon positif terhadap tanaman sawi. Dengan demikian pemberian kapur, kompos, N, P, dan K berpengaruh terhadap pertumbuhan tanaman sawi baik pada tinggi tanaman maupun biomassanya
Prominent and persistent loss of past awareness in amnesia: delusion, impaired consciousness or coping strategy?
No full textProfound loss of awareness for the past in amnesia has implications for our understanding of memory and belief systems, and how they may become disrupted in neurological conditions. We report the case of CW, a professional musician who became severely amnesic in 1985 following herpes simplex viral encephalitis (HSVE) at the age of 46 years. For many years CW stated several times a day that he had just woken up. He frequently wrote this in his diary too. When shown examples of his diary entries or videos of himself playing or conducting music, he recognised both his handwriting and himself on the video screen but stated vehemently that he “was not conscious then”. In a previous paper (Wilson, Baddeley, & Kapur 1995), it was suggested that this lack of awareness for the past was a delusion, defined as a strongly held belief in the face of contradictory evidence (rather than implying any kind of psychiatric disorder per se). As a contribution to the academic debate regarding theories of “self”, in the present paper we will review this explanation of CW's state as it had been in those early years, and we will also consider two other possibilities - namely, that CW had suffered from a loss of “autobiographical self” or “extended consciousness” (see Damasio, 2000, pp. 198-199), and that his verbal reports simply reflected a form of coping strategy to help him deal with the limited evidence he had available in “declarative” memory
Item recognition is less impaired than recall and associative recognition in a patient with selective hippocampal damage
No full textThis article explores the recall, item recognition, and associative recognition memory of patient B.E., whose pattern of retrograde amnesia was reported by Kapur and Brooks ([1999]; Hippocampus 9:1-8). Structural magnetic resonance imaging (MRI) has shown that B.E. has bilateral damage restricted to the hippocampus. The structural damage he had sustained was accompanied by bilateral hypoperfusion of the temporal lobe, revealed by positron emission tomography (PET), and which single photon emission computed tomography (SPECT) suggested was greater in the left than the right temporal lobe. B.E. showed a global anterograde amnesia for verbal material, but he displayed some sparing of nonverbal item recognition relative to nonverbal recall and associative recognition. His performance on an item recognition task that used the remember/know procedure and another that involved repetition of the test phase, to reduce the difference between the familiarity of the targets and foils, suggested that his relatively spared nonverbal item recognition may have been mainly supported by familiarity. This finding is consistent with the view that the anterior temporal lobe, including the perirhinal cortex, can support familiarity-based memory judgments (Brown and Bashir, [2002]; Philos Trans R Soc Lond B 357:1083-1095). B.E.'s data also highlight the importance of functional as well as structural scan information for interpreting the pattern of memory deficits shown by patients with selective hippocampal structural lesions. © 2004 Wiley-Liss, Inc

The neuropsychology of variant Creutzfeldt-Jacob Disease.
No full textWe report the neuropsychological profile associated with variant Creutzfeldt–Jakob disease (vCJD). A retrospective study was carried out of data from neuropsychological reports prepared on 24 patients with vCJD. While there was some variability in neuropsychological profiles, the overall pattern was one of a combined cortical and subcortical dementia, with impaired performance being particularly prominent on tests of memory, executive function, speed of attention, and visuoperceptual reasoning. Across 16 cases where Wechsler Adult Intelligence Scale-Revised intelligence quotient (IQ) scores were available, this profile was in part reflected by an invariably low performance IQ (<90 in all patients). All patients who received tests of verbal fluency, digit-symbol substitution and faces recognition memory showed deficits on these tests. Basic vocabulary, digit span and verbal reasoning skills were relatively preserved in most patients. In four cases who underwent more detailed cognitive testing, additional observations were made of relatively intact long-term autobiographical memory and faces perception. Cognitive impairment may represent one of the earliest features of vCJD and it is possible that, at least in some cases, neuropsychological deficits precede the onset of psychiatric or neurological symptoms. Our findings may help in the early detection and management of patients with vCJD
Technological memory aids for people with memory deficits
No full textThis paper reviews the application of external memory aids and computer-based procedures for the enhancement of memory functioning in neurological patients particularly adults with non-progressive brain injury and those with mild/moderate memory deficits. Memory aids may function as event memory aids to improve prospective memory functioning (Herrmann et al., 1999), or as knowledge memory aids to facilitate the acquisition and utilisation of factual information. We review the range of available external memory aids and evidence on their efficacy in clinical settings. Several studies have shown that external memory aids act as effective reminders and improve prospective memory functioning. Computer-based resources and procedures for improving memory functioning include those that serve similar functions to external memory aids, those which present memory tasks as memory retraining exercises, those which instruct the individual in the use of memory strategies, those which directly assist in domain-specific knowledge acquisition, and those which form the basis of "virtual reality" memory rehabilitation procedures. While there may be potential for computer-based procedures, there is at present only limited evidence on their efficacy and cost-effectiveness. We outline practical issues relating to the implementation of memory aids in clinical settings. We consider future developments that may impact on the application of external memory aids and computers in the treatment of human memory disorder
