Kajian pendahuluan perairan danau laut tawar di Takengon, Propinsi Daerah Istimewa Aceh (Preliminary study on Lout Tawar Lake in Takengon, Aceh Province)

ABSTRAK Kajian pendahuluan mengenai perairan Danau Laut Tawar telah dilakukan, khususnya mengenai kualitas air, komunitas fitoplankton dan komunitas benthos. Pengumpulan daja dilakukan pada musim kemarau yaitu pada bulan Oktober, dan pada musin hujan yaitu pada bulan Januari. Hasil, penelitian menunjukkan bahwa kualitas perairan Danau Laut Tawar relatif balk, yang berarti tidak terlihat adanya pengaruh negatif kegiatan niasyarakat terhadap kualitas perairan tersebut. Namur) demikian, gejala perubahan kualitas perairan ini telah terjadi. Hal ini terlihat dari perairannya oligotrifik yang didominasi oleh Chlorophyceae dan gulma air yang tumbuh subur, seperti Ilydrilla sp. dan Eichornia crassipes (eceng gondok). Gejala ini perlu diwaspadai karena gulma air tersebut dapat mengancam kelestariart perairan danau ini. Keistimewaan perairan Danau Laut Tawar adalah dijumpainya ikan khas, yaitu ikan depik (Rasbora tawarensis) yang tergolong endemik. Kata kunci: kualitas air, komunitas fitoplankton, komunitas bentho

Students multicultural awareness

Multicultural awareness is the foundation of communication and it involves the ability of standing back from ourselves and becoming aware of our cultural values, beliefs and perceptions. Multicultural awareness becomes central when we have to interact with people from other cultures. People see, interpret and evaluate things in a different ways. What is considered an appropriate behaviour in one culture is frequently inappropriate in another one. this research use descriptive- quantitative methodology to indentify level of students multicultural awareness specifically will be identified by gender and academic years. This research will identify multicultural awareness based on differences of gender, academic years. This research use random and purposive random sampling of 650 students from university. These studies identify of multicultural awareness 34, 11, 4% in high condition, 84, 1% medium and 4, 5% in low. Further, there is a significant difference in the level of multicultural awareness based on gender and academic year. These findings could not be generalized because of the limited sample and ethnicity; it should need a wider research so that can be generalized and recommended the efforts to development and improvement of multicultural awareness conditions for optimization the services

Tingkat Kecerdasan Sosial Mahasiswa Fakultas Keguruan dan Ilmu Pendidikan Universitas Kanjuruhan Malang

Specifically this study attempts to 1) provide information accurate data about levels of students social intelligence 2) To present an accurate data about the level of students social intelligence based on ethnicity. This research use descriptive- quantitative methodology. This research use purposive sampling of 120 students Faculty of Education. Research instrument used social intelligence scale consisting of 70 items. Data were processed using descriptive statistics and ANOVA test. Based on these results we can conclude that 1) 61.7% Students are at a high level of social intelligence, 38.3% Students are at moderate levels of social intelligence, 0% Students are at a low level of social intelligence; 2) There are significant differences between the scores of social intelligence in all regions

Chimeric genes in acute leukemias

In this thesis the genetic analysis of two types of acute leukemia characterized by translocations will be described. Both translocations generate chimeric genes which are specific for these subtypes of leukemia. The non-random changes that occur at the molecular level can be used in addition to karyotyping to diagnose the presence of tumor cells. The linkage of specific subtypes of acute myeloid leukemia with t(6;9) to a consistent rearrangement involving the ~-gene on chromosome 6 and the g.n-gene on chromosome 9 will be shown (Chapters III.2 and ill.3). This is of clinical importance since a correct diagnosis and subclassification indicates the prognosis of the diaease and helps to choose the right therapy, thereby improving the prognosis for a patient. The second type of acute leukemia that will be discussed is the acute lymphoblastic leukemia associated with the t(9;22). Here, rearrangement of genes results in a chimeric bcr-abl gene on the Philadelphia chromosome. A variant of this chimeric gene was found and analyzed (Chapter II.3). The study of altered genes in leukemia provides us with a multitude of questions conceroing their function and role in the origin of the tumor. However, unusual variants of tumor-specific products may help to solve parts of the mystery of tumor formation

Pfeiffer syndrome

Pfeiffer syndrome is a rare autosomal dominantly inherited disorder that associates craniosynostosis, broad and deviated thumbs and big toes, and partial syndactyly on hands and feet. Hydrocephaly may be found occasionally, along with severe ocular proptosis, ankylosed elbows, abnormal viscera, and slow development. Based on the severity of the phenotype, Pfeiffer syndrome is divided into three clinical subtypes. Type 1 "classic" Pfeiffer syndrome involves individuals with mild manifestations including brachycephaly, midface hypoplasia and finger and toe abnormalities; it is associated with normal intelligence and generally good outcome. Type 2 consists of cloverleaf skull, extreme proptosis, finger and toe abnormalities, elbow ankylosis or synostosis, developmental delay and neurological complications. Type 3 is similar to type 2 but without a cloverleaf skull. Clinical overlap between the three types may occur. Pfeiffer syndrome affects about 1 in 100,000 individuals. The disorder can be caused by mutations in the fibroblast growth factor receptor genes FGFR-1 or FGFR-2. Pfeiffer syndrome can be diagnosed prenatally by sonography showing craniosynostosis, hypertelorism with proptosis, and broad thumb, or molecularly if it concerns a recurrence and the causative mutation was found. Molecular genetic testing is important to confirm the diagnosis. Management includes multiple-staged surgery of craniosynostosis. Midfacial surgery is performed to reduce the exophthalmos and the midfacial hypoplasia

KBG syndrome

KBG syndrome is a rare condition characterised by a typical facial dysmorphism, macrodontia of the upper central incisors, skeletal (mainly costovertebral) anomalies and developmental delay. To date, KBG syndrome has been reported in 45 patients. Clinical features observed in more than half of patients that may support the diagnosis are short stature, electroencephalogram (EEG) anomalies (with or without seizures) and abnormal hair implantation. Cutaneous syndactyly, webbed short neck, cryptorchidism, hearing loss, palatal defects, strabismus and congenital heart defects are less common findings. Autosomal dominant transmission has been observed in some families, and it is predominantly the mother, often showing a milder clinical picture, that transmits the disease. The diagnosis is currently based solely on clinical findings as the aetiology is unknown. The final diagnosis is generally achieved after the eruption of upper permanent central incisors at 7–8 years of age when the management of possible congenital anomalies should have been already planned. A full developmental assessment should be done at diagnosis and, if delays are noted, an infant stimulation program should be initiated. Subsequent management and follow-up should include an EEG, complete orthodontic evaluation, skeletal investigation with particular regard to spine curvatures and limb asymmetry, hearing testing and ophthalmologic assessment
