    One type of potential fish catches in West Kutai is fish Baung (Mystus numurus C.V, 1840). Fish Baung marketed so far show the relative sizes vary from time to time. Therefore, in order Baung fish resource utilization can be maintained, the necessary information about the fish gonad maturity can be determined by calculating the gonad maturation index (IKG). This study aims to determine: (1) the index of gonad maturity Baung fish landed in TPI Bohoq and (2) the size of fish Baung matured genitals first. This study uses an analytical approach with ELEFAN I (electronic length frequency analysis) contained in FISAT II software version 1.2.2. thus, can be obtained information for sustainable management of fish Baung by comparing the results of the analysis of gonad maturity index with descriptive analysis results ELEFAN. The results showed that: (1) IKG average obtained from 25 fish Baung gonads was 10.19%, and (2) fish Baung mature gonads was first on the length of 39-48 cm with a weight of 1250-1849 grams

    Symmetry, incommensurate magnetism and ferroelectricity: the case of the rare-earth manganites RMnO3

    The complete irreducible co-representations of the paramagnetic space group provide a simple and direct path to explore the symmetry restrictions of magnetically driven ferroelectricity. The method consists of a straightforward generalization of the method commonly used in the case of displacive modulated systems and allows us to determine, in a simple manner, the full magnetic symmetry of a given phase originated from a given magnetic order parameter. The potential ferroic and magneto-electric properties of that phase can then be established and the exact Landau free energy expansions can be derived from general symmetry considerations. In this work, this method is applied to the case of the orthorhombic rare-earth manganites RMnO3. This example will allow us to stress some specific points, such as the differences between commensurate or incommensurate magnetic phases regarding the ferroic and magnetoelectric properties, the possible stabilization of ferroelectricity by a single irreducible order parameter or the possible onset of a polarization oriented parallel to the magnetic modulation. The specific example of TbMnO3 will be considered in more detail, in order to characterize the role played by the magneto-electric effect in the mechanism for the polarization rotation induced by an external magnetic field.Comment: Conference: Aperiodic`0

    High-intensity exercise training induces morphological and biochemical changes in skeletal muscle

    Skeletal muscle shows an elevated plasticity and can adapt its metabolic and contractile properties in response to a variety of stimuli such as physical exercise. This implies a series of biochemical and morphological changes in the recruited muscle, in order to produce the more appropriate functional response dependent on the specific stimulation. To determine the effective role of physical exercise in the muscle plasticity, in the present study we investigated the effect of two different exercise protocols on fiber composition and metabolism of two specific muscles of mice: the quadriceps -a fast-twitch muscle- and the gastrocnemius -a typical slow-twitch muscle. Mice were run daily on a motorized treadmill for 8 weeks, at a velocity corresponding to 60% (low-intensity exercise) or 90% (high-intensity exercise) of the maximal running velocity previously determined by an incremental exercise test. We found that at the end of training the body weight was significantly increased in highintensity exercise mice (18.2 ± 1.4 %) compared to low-intensity exercise (8.7 ± 0.6 %) and control (12.7 ± 0.5 %) groups, and it was lesser in low-intensity exercise mice compared to controls. In contrast, the food intake of both exercise training mice was greater compared to control group. Whereas low-intensity exercise mice, despite consumed significantly more food compared to control mice, increased the weight lesser, the weight increase of high-intensity exercise mice, that consumed significantly more food compared to other experimental groups, was significantly greater. These effects were accompanied by a progressive reduction in blood lactate levels at the end of training in both the exercised mice compared with controls; in particular, blood lactate levels after highintensity exercise were significantly lower than those measured in low-intensity exercise mice. Moreover, in the present study we demonstrated that high-intensity exercise training produced a significant increase in the expression of mitochondrial complex enzymes (significant for the enzymes corresponding to the Complex IV, II and I of mitochondrial chain) both in gastrocnemius and quadriceps muscle, compared with controls. These changes were associated with an increase in the amount of slow fibers in both these muscle of high-intensity exercise mice. No changing in the expression of mitochondrial enzymes and in the percentage of slow fibers were found in low-intensity exercise mice

    yang ber-KeTuhanan, hukum mesti ditegakan dalam segala aspek kehidupan manusia. Hukumbukanlah suatu skema yang final, namun terus bergerak, berubah, mengikuti dinamika kehidupanmanusia. Karena itu, hukum tetap terus dibedah dan digali melalui usaha-usaha nyata untukmencapai terang cahaya kebenaran dalam menggapai keadilan. Manusia selaku aktor terpentingdan utama dibelakang kehidupan hukum tidak hanya dituntut untuk mampu menciptakan danmenjalankan hukum (making the law), tetapi juga keberanian untuk mematahkan danmerobohkannya (breaking the law) manakala hukum tidak sanggup menghadirkan roh dansubstansi keberadaannya, yakni mampu menciptakan keharmonisan, kedamaian, ketertiban, dankesejahteraan masyarakatnya. Dalam proses penegakan hukum, agar tidak mencederai rasakeadilan masyarakat, mengikuti prosedur dan mekanisme yuridis semata, menerapkan pasal-pasaldan bunyi undang-undang saja, melainkan proses yang melibatkan perilaku-perilaku masyarakatyang berlangsung dalam struktur sosial tertentu. Misalnya saja, seorang hakim tidak bolehmenolak suatu perkara yang diajukan kepadanya dengan alasan tidak ada hukum yang mengaturberkenaan dengan obyek perkara yang diajukan, atau hakim tidak mengetahui hukumnya. Hakimdalam memutuskan suatu perkara harus bisa menemukan hukumnya (rechtvinding) danmembentuk hukum baru (rechtvorming) jika perkara yang diajukan kepadanya belum ada hukumtertulis yang mengaturnya, karena hukum tidak saja bersifat tatanan aturan secara tekstual an sich(ordegenik) tetapi juga dalam tatanan kontekstual berbasis fleksibel. Dengan demikian sebuahperistiwa hukum, ketika diajukan dalam proses peradilan, hakim membutuhkan dokumen transaksi(bukti-bukti dan alat bukti) yang cukup, dan dapat dijadikan sebagai dasar pertimbangan dalammemeriksa, memutus, dan mengadili sebuah perkara. Dan disanalah peran besar seorang ahliakuntansi keuangan (AAK)

    In the business world the use of management is still relatively new.The economic literature of the 19th and 20th centuries is stillunknown to him. The writers at that time, used the terms owner,businessman or capitalist to express those who ran commercial,trade or factory businesses. Modern humans could be said to behuman beings who endeavored without being alone, but ratherthrough them through joint ventures in organizations / companies.Here there are individual relationships with organizations /companies that are reciprocal with a high level of interdependenceand interaction. These interdependencies and interactions areplayed in the role and role of a very important 'leader'. In essence,the dynamics of organizational / corporate life require properbehavior from employees in the sense of encouraging, and fosteringa willingness to bring personal interests to broader interests,namely business interests in the company as a whole in the controlof someone professional manager (ecsseccutivelly professionalleader)
