Latar Belakang : Asupan tinggi energi dari lemak jenuh meningkatkan risiko CHD khususnya pada wanita. Kelainan profil lipid ini erat hubungannya dengan proses perkembangan atherosklerosis. Penelitian epidemiologi, laboratorium dan klinik menunjukkan hubungan peningkatan kejadian penyakit kardiovaskular dan penyakit degeneratif lainnya dengan kadar kolesterol yang tinggi. Metode : Rancangan Penelitian adalah crossecional. Subyek penelitian adalah 30 karyawati RSUD Kendal umur 35 – 50 tahun.Pemeriksaan kadar kolesterol total, kadar kolesterol LDL diukur dengan vitros system chemistry analyser 300 di laboratorium patologi klinik RSUD Kendal. Asupan gizi diukur dengan metode food recall 24 dihitung dengan program Nutrisurvey. Analisis data menggunakan uji Shapiro Wilk dan uji korelasi Spearman. Hasil dan Pembahasan : Hasil analisa data adalah ada hubungan asupan energi dengan kadar kolesterol total (p=0,016, r=0,434), ada hubungan kuat asupan lemak dengan kadar kolesterol total (p=0,01, r=0,593), ada hubungan asupan lemak dengan kadar LDL (p=0,011, r=0,456) dan tidak ada hubungan asupan energi dengan kadar LDL (p=0,1119, r=0,291), Asupan tinggi energi mengakibatkan penimbunan lemak terutama trigliserida. Hal ini akan meningkatkan VLDL dan IDL darah yang akan berujung dengan peningkatan kolesterol total. Semakin tinggi seseorang mengkonsumsi makanan berlemak, maka timbunan kadar lemak dan trigliserida di dalam tubuh akan meningkat. Hal ini akan meningkatkan VLDL dan IDL darah. Simpulan : Ada hubungan asupan energi dengan kadar kolesterol total (p=0,016, r=0,434), ada hubungan kuat asupan lemak dengan kadar kolesterol total (p=0,01, r=0,593) dan kadar LDL (p=0,011, r=0,456).

Abstract. Based upon the well-understood carbonate system chemistry over global ocean surface (above the wintertime thermocline and shallower than upper 100 m), we investigated potentials of wintertime ocean surface DIC (dissolved inorganic carbon) to rise in response to the decadal air–sea re-equilibration, and the corresponding anthropogenic CO2 accumulation rates. For a reference year 2000, the potentials of wintertime DIC to rise in response to the rising atmospheric CO2 mole fraction ranged from 0.28 to 0.70 μmol kg−1 ppm−1 (ppm = parts of CO2 per million dry air) over the global open ocean surface, while the global mean wintertime surface DIC increase rate was close to 1.0 μmol kg−1 yr−1. The decadal anthropogenic CO2 accumulation rate within the surface ocean was estimated at 0.31 × 1015 g C yr−1 around the reference year 2000, accounting for a non-negligible component (likely 12 to 14%) of the recent oceanic sink for anthropogenic CO2. From 1960s to 2000s, this rate likely increased by 47% due to the accelerated atmospheric CO2 rise. However, the ocean surface anthropogenic CO2 accumulation potential under a unit atmospheric CO2 rise may have declined by 16% during the same period.

Thermoplastic polymers can be viewed as a dynamic framework in which additives allocation is strongly dependent on the system' chemistry. Considering the complexity of the distribution phenomena that may occur in plastics obtained by blending polymeric resins with different additives, this work constitutes an attempt to the description of the behavior of PVC heat stabilizers (calcium and zinc carboxylates), as regard temperature and time. Thanks to the Fourier Transform Infrared Spectroscopy, it is possible to observe a first decreasing trend of the additives related IR-bands as a function of the increasing temperature and the higher the temperature the faster the decrease of the heat stabilizers intensities bands is, with respect to time. Additives distribution in not sterilized, sterilized, aged not sterilized and aged sterilized materials have been investigated to determine their behavior with respect to temperature, from 30 to 120°C, and time. A simulated supplementary aging process equivalent to 9 months aging was carried out on aged not sterilized and aged sterilized materials to gain more data on the transport/reaction phenomena these additives in the plastic material. Experimental evidences allow hypothesizing that reaction and redistribution phenomena probably concur to determine the additives allocation in PVC as a function of temperature and time.
