AbstractWe give a relatively simple proof of the theorem on the spectral sequence of a fibre-space in the sense of Kan. The method consists in the reduction to locally trivial fibre-spaces by minimal fibrings and in the use of a very simple acyclic model theory (without degeneracies).

AbstractAsymptotic extremal combinatorics deals with questions that in the language of model theory can be re-stated as follows. For finite models M, N of an universal theory without constants and function symbols (like graphs, digraphs or hypergraphs), let p(M, N) be the probability that a randomly chosen sub-model of N with ∣M∣ elements is isomorphic to M. Which asymptotic relations exist between the quantities p(M1,N),…, p(Mh,N), where M1,…, M1, are fixed “template” models and ∣N∣ grows to infinity?In this paper we develop a formal calculus that captures many standard arguments in the area, both previously known and apparently new. We give the first application of this formalism by presenting a new simple proof of a result by Fisher about the minimal possible density of triangles in a graph with given edge density.

Peningkatan suhu tubuh  menyebabkan rasa tidak nyaman, gelisah pada anak, sehingga waktu untuk istirahat menjadi terganggu.Tatalaksana pada anak dengan demam dapat dilakukan dengan metode farmakologi dan non farmakologi. Tepid water spongingmerupakan tatalaksana non farmakologi. Konservasi adalah serangkaian sistem agar tubuh manusia mampu menjalankan fungsi, beradaptasi untuk melangsungkan kehidupan. Perawat mempunyai peran untuk membantu anak dalam mengatasi gangguan termoregulasi. Karya ilmiah ini bertujuan untuk mengetahui efektifitas penurunan suhu tubuh menggunakan tepid water sponging dengan pendekatanl konservasi Levine di ruang rawat infeksi. Efektifitas diukur dalam pemberian asuhan keperawatan berdasarkan proses keperawatan yang terdapat dalam model konservasi Levine yaitu: pengkajian, menentukan trophicognosis, menentukan hipotesis, intervensi dan evaluasi. Terdapat lima kasus yang dibahas. Hasil penerapan model konservasi Levine mampu meningkatkan kemampuan anak dalam mempertahankan fungsi tubuh dan beradaptasi terhadap perubahan. Kombinasi tepid water sponging dan terapi farmakologi mampu mengatasi demam dengan cepat dibanding terapi farmakologi.   Kata kunci: termoregulasi, tepid water sponging, teori model konservasi Levine   REDUCTION OF BODY TEMPERATURE USING TEPID WATER SPONGINGWITH THE LEVINE CONSERVATION APPROACH   ABSTRACT Increased body temperature causes discomfort, anxiety in children, so that the time to rest becomes disturbed. Management of children with fever can be done by pharmacological and non-pharmacological methods. Tepid water sponging is a non-pharmacological treatment. Conservation is a series of systems so that the human body is able to function, adapt to life. Nurses have a role to help children overcome thermoregulation disorders. This scientific work aims to determine the effectiveness of decreasing body temperature using tepid water sponging with the approach of Levine conservation in the infectious care room. Effectiveness is measured in the provision of nursing care based on the nursing process contained in the Levine conservation model, namely: assessment, determining trophicognosis, determining hypotheses, intervention and evaluation. There are five cases discussed. The results of the application of the Levine conservation model are able to improve the ability of children to maintain body functions and adapt to changes. The combination of tepid water sponging and pharmacological therapy is able to overcome fever quickly compared to pharmacological therapy.   Keywords: thermoregulation, tepid water sponging, Levine conservation model theory
