Résumé :

This paper focuses on computational fluid dynamics (CFD) simulation of the dynamic exploited influence of wind field in the open pit quarry. We have picked up 3 normal exploitation parameters, e.g. the exploited depth z, the type of small hills and the measured velocity u1, 7 simulated experiments have been done by software Fluent as well. In our experiments, the features of velocity field around the mine are shown, with the effects of open pit quarry, so as to analyze the changes of wind speed when it gets through this mine. To be exact, it will be possible to deduce there is negative correlation between the velocity decreased gratitude and the exploited depth. Besides, with the shelter effect of a small hill, the wind speed tends to slow down near this hill, and turn back to rise until the flow leaves the hill far away. The velocity decreasing has positive correlation with the measured velocity u1, and the reverse flow is more likely to appear with higher u1.

Résumé :

Objective. This study aims to clinically investigate and compare the therapeutic effects and treatment cycle between traditional direct bonding and OrthGuide computer-aided indirect bonding in orthodontic treatment. Methods. Forty patients treated at the Department of Orthodontics, Beijing Rytime Dental Hospital between July 1, 2016, and December 31, 2019, were included. The patients were divided into a control group ( n = 20 , traditional direct bonding) and a test group ( n = 20 , OrthGuide computer-aided indirect bonding). The American Board of Orthodontics (ABO) measurement was performed on patients using Uceph cephalometric analysis software to compare intragroup and intergroup differences, and the treatment cycles of all patients were recorded. Results. After treatment, U1-NA (mm), ∠U1-SN (°), LL-EP (mm), and UL-EP (mm) in the control group were significantly lower than before treatment, and there was no significant difference in other ABO measurement indexes, while the test group showed no marked difference in all ABO measurements between pre- and posttreatment. Further, intergroup comparison showed no significant difference in ABO measurements in pre- and posttreatment between the two groups. The test group had a shorter treatment cycle than the control group, with an average treatment cycle of 21.20 ± 7.14 months in the control group and 17.17 ± 4.16 months in the test group. Conclusion. There was no significant difference in the therapeutic effects between the direct and indirect bonding techniques. However, OrthGuide computer-assisted indirect bonding demonstrated a significantly shorter treatment cycle and might be more efficient than traditional direct bonding.

Résumé :

Organic farming is a good way to reduce environmental pollution. However, no related detection of fertilizer applications, which are extremely important in organic farming, exists. The δ15N value of chemical fertilizer (–3.8 to +2‰) is far lower than compost (>+10‰). Thus, natural 15N abundance (δ15N) in leaves and fruits may be used to reveal the application of N fertilizer. In this experiment, six treatments were laid out: 635 g (C1), 952 g (C2), and 1270 g (C3) of compost were applied as basal fertilizer in each pot. Alternately, 10.7 g (U1), 16 g (U2), and 21.3 g (U3) of urea were applied as basal fertilizer and 10.7 g (U1), 16 g (U2), and 21.3 g (U3) urea were applied as top-dressing, respectively, in each pot. C1 and U1, C2 and U2, and C3 and U3 had equal amounts of nitrogen fertilization. In all three fertilizer levels, the leaves and fruits sampled from the U group had significantly lower values than those sampled from the C group within the same period. The δ15N values of the leaves and fruits from the C group decreased slowly. The δ15N values of leaves sampled at 40 days after transplanting were fairly low. The δ15N values of leaves and fruits from the U group increased initially, due to the small amounts of urea left, which then led the plants to absorb N from the culture substrates. However, the δ15N values of leaves and fruits from the U group decreased rapidly after the top-dressing was applied, where the minimum values occurred during the final stage.

Résumé :

In this study,Zingiber officinale(ginger) rhizome fine particles were prepared by using food processor, hammer mill and planetary ball mill and tested for their physical and thermal properties. The physical changes by means of particle size, surface morphology, FT-IR and thermal stability (TGA) were investigated. The size reduction method had a distinct effect on physical and thermal properties of ginger rhizome tested. Average particle size of ginger rhizome after using food processor and hammer mill was around 50µm and 20µm respectively while after using planetary ball mill the ginger rhizome was successfully reduced to nanoscale (222.3 nm). Higher degree of granule surface fractured was observed as a result of a planetary ball milling process based on FESEM images. There were also some notable differences of FT-IR spectra detected. By comparing the spectra, the stretching vibration peak of OH at 3292 cm-1[U1]and the symmetric stretching vibration peak of the NO2and C=C at 1369 – 1639.51cm-1 for ginger rhizome ground using food processor were disappeared. Yet, presence of possibly strong alkenes group (in the range 2850 – 2970cm-1) were observed in all samples tested. Ginger rhizome particles obtained from hammer milling process were found to be more stable to thermal effect where the decomposed temperature was 276.64°C as compared to samples milling using food processor and planetary ball mill. These results would provide useful insight for exploring the potential applications of ginger rhizome fine powder as functional food ingredient as well as in pharmaceutical applications.

Résumé :

ABSTRACT Context: The existence of more than one antibody in systemic autoimmune rheumatic diseases (SARDs) or connective tissue disease (CTD) along with features of more than one autoimmune disease (AD) in an individual is suggestive of overlap syndrome (OS). Line immunoassay (LIA) can target many autoantibodies in a single approach, thus making the identification of OS feasible. Aims and Objectives: This study aimed to identify the pattern of distribution of antinuclear antibodies by LIA prevalent in a hospital population in eastern India and identify common forms of SARD in this belt based on laboratory findings. Material and Methods: A total of 1660 samples received for ANA profile testing by LIA were analysed. Statistical Analysis: Factor analysis was performed with factor loading scores used in the k-means algorithm to identify clustering of various autoantibodies. Results: U1-snRNP positivity was the highest at 16.69%, and the least frequent autoantibody noted was anti-Jo-1 at 0.71% positivity. Based on the outcome of factor analysis, three clusters were determined. Cluster 1 showed a predominance of anti-PM/Scl antibodies, cluster 2 showed a predominance of anti-dsDNA, anti-histone, anti-SmD1, anti-nucleosomes, anti-PCNA, anti-Po, anti-SSA/Ro52, anti-SSA-Ro60, anti-SSB/La, anti-Scl-70, anti-Mi-2, anti-Ku and anti-AMA-M2, and cluster 3 showed a predominance of anti-U1-snRNP. Conclusions: Mixed connective tissue disease (MCTD) and overlap syndrome (OS) are prevalent more than pure form of an AD in our study population. OS may be missed out by monospecific immunoassays and hence adds to diagnostic challenges. LIA may be more useful in identifying specific autoantibodies by a single approach rather than monospecific immunoassays in populations after a positive screen by indirect immunofluorescence (IIF).

Résumé :

Electrical resistance method was used to detect layer moisture content across the thickness of Larch (Larix gmelinii) specimen during drying, and the temperature of the same layers and the environment were also measured by remote temperature scanner. During the drying process, layer moisture content was obtained from other Larch specimens with slicing method. Layer moisture content measured with electrical method was compared with that acquired with slicing method. Results showed that the wood center temperature was more suitable than the environment temperature as compensated temperature to amend moisture content measuring with electrical resistance method; variation of layer moisture content of Larch specimen could be more or less measured with electrical resistance method, and had a relatively good agreement with that acquired with slicing method except that u15 was 3% higher than U1 and u3 was 4% higher than U3 in the middle stage of drying.

Résumé :

Mycorrhiza is a biological agent to help fertility of soil and plants. Application of mycorrhiza on the land in the form of inoculum is often used in agricultural land in the name of quality of inoculum that also influenced by the content of existing spores. One of them is growing medium. This study aimed to study the effect of soil aggregate size and P dosage on the number of mycorrhizal spores in sorghum plants. The research design used was Randomized Block Design consisting of 2 factors. First factor was soil aggregate size(μm) which consisted of 4 treatments: U1 = < 2000, U2 = 500 - 1000, U3 = 200 - 500, U4 = < 200, and second factor was P dosage: 100 mg/kg and 300mg/kg. Each treatment combination was repeated 3 times so that there were 24 units of experimental unit. Observation parameters included the percentage of the infected root, number of spores, plant height and dry weight of the plant. The research was conducted in Greenhouse and Agronomy Laboratory of Agricultural Faculty of Tadulako University Palu. The various sizes of soil aggregates do not affect the amount of arbuscular mycorrhizal spores in sorghum plants. P 100 mg/kg or f P 300 mg/kg dosage used do not address the effect of the mycorrhizal spores. There is no interaction between soil aggregate size and P dosage to the amount of mycorrhizal spores in sorghum plants.

Résumé :

Curing is the key to the bonding, this paper considered the production practice, studied the curing properties of different MUF resin under the different curing agent with DSC. The experimental results show that: The characteristics temperature of curing reaction is closely related to the β. With the increase of β, the initial and peak temperature is moving to the high-temperature, the curing time became shorter; the range of curing temperature became much wider. At the same time, the curing peaking temperature was decreased and the Enthalpy integral of curing reaction was reduced first then increased with the increased of the amount of curing agent. When the amount of curing agent occupied 4.0%-6.0% of the MUF resin, the pH was decreased mostly, and the curing reaction rate run up quickly Along with the increasing of n (F): n (U1), the To, Tp and Ti are going ahead distinctly after hardening. At the same time, both activation energy and reaction order are all decreased, absorbed heat is dropping too. So, curing technics became easily.

Texte intégral

Résumé :

Au cours d’études sur la polyadénylation alternative (APA), des transcrits courts terminant dans un exon final alternatif ont été découverts, on parle de polyadénylation intronique (IPA). L’IPA est régulée par des facteurs de l’épissage (dont U1 snRNP), de polyadénylation, et d’élongation de la transcription (dont CDK12). Les isoformes IPA sont régulées par des agents génotoxiques (induisant des dommages à l’ADN), dont les rayonnements UV et la doxorubicine. Les inhibiteurs de CDK12 augmentent l’IPA dans des gènes de réparation de l’ADN et la sensibilité cellulaire à des génotoxiques. L’IPA a souvent lieu dans la région codante des gènes, générant des protéines altérées en carboxy terminal. Cependant, des transcrits IPA sont aussi générés dans les premiers introns des gènes, on parle alors de 5’IPA. Des transcrits 5’IPA sont dégradés par l’exosome nucléaire, mais certains sont abondants et ont un faible potentiel codant. Deux d’entre eux, issues des gènes ASCC3 et CDKN1A, ont des fonctions non codantes. Par ailleurs, des études montrent par Ribo-seq et spectrométrie de masse (MS) l’existence, dans des ARNm et des lncRNA, de petits cadres de lecture ouverts (sORF) codant des microprotéines (miP, protéines de moins de 100 aa) qui peuvent être fonctionnelles. Aucune miP n’a été rapportée dans des isoformes 5’IPA. Le cisplatine (CisPt) est un agent pontant de l'ADN très utilisé dans les cancers du poumon non à petites cellules (NSCLC). Mon équipe a observé par 3’-seq dans des cellules NSCLC que le CisPt augmente l’expression des isoformes IPA par rapport aux ARNm canoniques (ratio IPA:LE) dans de nombreux gènes, et que certaines isoformes IPA sont peu engagées dans les polysomes lourds et sont issues de la région en amont du site d’initiation de la traduction annoté du gène (isoformes 5’UTR-IPA). Mes objectifs étaient de déterminer le rôle de l’IPA dans la réponse cellulaire au CisPt. Je me suis intéressé premièrement au rôle des isoformes 5’UTR-IPA. Pour deux d’entre elles, issues des gènes PRKAR1B et PHF20, j’ai montré que leur déplétion par siARN augmente la survie de cellules NSCLC au CisPt. Ces deux isoformes sont engagées dans des fractions polysomiques légères. Des analyses de bases de données de Ribo-seq et de MS ont révélé l’existence de sORF dans ces deux isoformes. Par transfection de vecteurs contenant ces isoformes 5’UTR-IPA et en balisant leurs sORF, j’ai observé en ImmunoFluorescence (IF) et Western Blot que l’isoforme 5’UTR-IPA de PRKAR1B code une miP. La délétion de cette isoforme IPA endogène ou la mutation de l’ATG de sa sORF par CRISPR ont donné un phénotype similaire au siARN. Il s’agit de la première isoforme 5’UTR-IPA codant une miP (miP-5’UTR-IPA). Par croisement de nos données de 3’-seq avec des données de Ribo-seq et de MS, nous avons identifié une centaine d’isoformes miP-5’UTR-IPA potentielles induites par le CisPt. Deuxièmement, je me suis intéressé à la possibilité de sensibiliser des cellules NSCLC au CisPt en ciblant U1 snRNP par un oligonucléotide (U1-AMO) qui induit l’IPA dans de nombreux gènes. Dans plusieurs lignées cellulaires NSCLC, j’ai pu montrer une sensibilisation par U1-AMO au CisPt en termes d’inhibition de croissance cellulaire et d’induction de dommages à l’ADN (foyers ƴH2AX). Cette sensibilisation est liée à une réduction (en 3’-seq et RT-qPCR) de l'expression des ARNm canoniques dans des gènes de réparation des pontages de l'ADN (voies de Fanconi et de l’excision de nucléotides). Cependant, U1-AMO prévient les blocages de cycle cellulaire induits par le CisPt, ainsi que les effets du CisPt sur le ratio IPA:LE de nombreux gènes. Mes travaux montrent l’impact de l’IPA sur la réponse des cellules cancéreuses au CisPt, et révèlent un nouveau paradigme génétique, appelé miP-5’UTR-IPA, dans lequel des gènes produisent par IPA des transcrits courts codant des miP
During studies on alternative polyadenylation (APA), short transcripts ending in an alternative last exon were discovered, known as intronic polyadenylation (IPA). IPA is regulated by splicing factors (including U1 snRNP), polyadenylation factors and transcription elongation factors (including CDK12). IPA isoforms are regulated by genotoxic agents (inducing DNA damage), including UV radiation and doxorubicin. Conversely, CDK12 inhibitors increase both IPA in DNA repair genes and cellular sensitivity to genotoxic agents. IPA often occurs in the coding region of genes, generating carboxy-terminally altered proteins. However, IPA transcripts are also generated in the first introns of genes, known as 5'IPA. Many 5'IPA transcripts are degraded by the nuclear exosome, but some are abundant and have a low coding potential. Two of these, derived from the ASCC3 and CDKN1A genes, have non-coding functions. In addition, studies using Ribo-seq and mass spectrometry (MS) are showing the existence -in mRNAs and lncRNAs- of small open reading frames (sORF) encoding microproteins (miP, proteins of less than 100 aa) which can be functional. No miP has been reported in 5'IPA isoforms. Cisplatin (CisPt) is a DNA-crosslinking agent widely used in non-small cell lung cancer (NSCLC). My team observed, by 3'-seq in NSCLC cells, that CisPt increases the expression of IPA isoforms compared to canonical mRNAs (IPA:LE ratio) in many genes, and that some IPA isoforms are poorly associated with heavy polysomes and are derived from the region upstream of the annotated translation initiation site of the gene (5'UTR-IPA isoforms). My objectives were to determine the role of IPA in cell response to CisPt. I first looked at the role of 5'UTR-IPA isoforms. For two of them, derived from the PRKAR1B and PHF20 genes, I showed that their depletion by siRNA increased the survival of NSCLC cells to CisPt. These two isoforms are associated with light polysomal fractions. Analyses of Ribo-seq and MS databases revealed the existence of sORFs in these two isoforms. By transfecting vectors containing these 5'UTR-IPA isoforms and by tagging their sORFs, I observed by ImmunoFluorescence (IF) and Western Blot that the 5'UTR-IPA isoform of PRKAR1B encodes a miP. Deletion of this IPA isoform or mutation of the sORF ATG endogenously by CRISPR gave a phenotype similar to the siRNAs. This is the first 5'UTR-IPA isoform encoding a miP (miP-5'UTR-IPA). By cross-referencing our 3'-seq data with Ribo-seq and MS data, we identified around a hundred potential miP-5'UTR-IPA isoforms induced by CisPt. Secondly, I investigated the possibility of sensitizing NSCLC cells to CisPt by targeting U1 snRNP with an antisense oligonucleotide (U1-AMO), that induces IPA in many genes. In several NSCLC cell lines, I showed sensitization to CisPt by U1-AMO in terms of cell growth inhibition and DNA damage induction (ƴH2AX foci). This sensitization is linked to a reduced expression of the canonical mRNAs of DNA crosslinks repair pathways (Fanconi and nucleotide excision repair), as shown by 3'-seq and RT-qPCR. However, U1-AMO prevented CisPt- induced cell cycle block and the effects of CisPt on the IPA:LE ratio of many genes. My work shows the impact of IPA on the response of cancer cells to CisPt, and reveals a new genetic paradigm, called miP-5'UTR-IPA, in which genes produce short miP-encoding transcripts by IPA

Résumé :

Many hydrocarbon reservoirs are situated in barren sequences that display poor stratigraphic control. Correlation between the wells can become extremely difficult and traditional correlation techniques can prove to be inadequate. Past studies have shown that trace and major element concentrations can be used as a correlation tool. This practice of using geochemical fingerprints to characterize between wells is called Chemostratigraphic analysis. (Pearce et al, 1999) Chemostratigraphy has been recognized as a very important correlation technique as it can be used for rocks of any age, in any geological setting as well as sequences that are traditionally defined as barren. Chemostratigraphic analyses can be used as a means of getting rid of ambiguities within data produced by traditional correlation methods such as Biostratigraphy, Lithostratigraphy and Geophysical Logging. In areas where stratigraphic data is not available it can be used to construct correlation frameworks for the sequences found in the area. The motivation behind this study is that the research is not only worthy of academic investigation, but can also provide the industry with new insights into areas that were previously misunderstood because traditional correlation methods were not adequate. The study area, the Orange basin, is located offshore South Africa and is largely underexplored. The basin, that hosts two gas field namely the Ibhubesi and the Kudu gas fields, has large potential but in the past has not been given due attention with only 34 wells being drilled in the area. The Orange basin has recently been the topic of investigation because of the belief that it may be hosts to more hydrocarbons. This study will utilise Chemostratigraphy to attempt to provide geological information on this relatively under-explored basin. The aim of this research study is to produce a chemostratigraphic framework -scheme for the Orange Basin in order to facilitate reservoir scale interwell correlation. The Objectives of this research study will be to identify chemostratigraphic units or indices, to prove the adequate use of chemostratigraphy as an independent correlation technique and to integrate the chemostratigraphy and petrophysical characteristics of the four wells to facilitate lithological identification.

Résumé :

Abstract Early supercritical units such as American Electric Power (AEP) Philo U6, the world’s first supercritical power plant, and Eddystone U1 successfully operated at ultrasupercritical (USC) levels. However due to the unavailability of metals that could tolerate these extreme temperatures, operation at these levels could not be sustained and units were operated for many years at reduced steam (supercritical) conditions. Today, recently developed creep strength enhanced ferritic (CSEF) steels, advanced austenitic stainless steels, and nickel based alloys are used in the components of the steam generator, turbine and piping systems that are exposed to high temperature steam. These materials can perform under these prolonged high temperature operating conditions, rendering USC no longer a goal, but a practical design basis. This paper identifies the engineering challenges associated with designing, constructing and operating the first USC unit in the United States, AEP’s John W. Turk, Jr. Power Plant (AEP Turk), including fabrication and installation requirements of CSEF alloys, fabrication and operating requirements for stainless steels, and life management of high temperature components

Résumé :

Hot–wire measurements reveal the evolution of three-dimensional TS (Tollmien-Schlichting) waves and other nonlinear disturbances generated by a ZNMF (Zero Net Mass-Flux) jet. The base flow consists of a highly two-dimensional Blasius boundary layer with extremely small extraneous background disturbance levels (u/U1 < 0.08 %). The response is shown to be linear and symmetrical for sufficiently small actuator amplitudes and under these conditions the TS wave motions conform with the PSE (Parabolized Stability Equations) results of Mack & Herbert (1995). The observations suggest that a small-amplitude ZNMF jet would be a suitable device for active LFC (Laminar Flow Control) applications. For larger actuator amplitudes, other short–wavelength instabilities develop and grow with streamwise development and they ultimately breakdown to form a turbulent wedge. There is an actuator amplitude threshold below which these instabilities do not form, and a larger threshold below which the instabilities do not grow with streamwise development. The characteristics of the turbulent wedge are also considered in some detail.

Résumé :

A narrow low-speed streamwise streak is deliberately introduced into an otherwise extremely spanwise uniform Blasius boundary layer. The streak shares many of the characteristics of Klebanoff modes known to be responsible for bypass transition at moderate Free Stream Turbulence (FST) levels. However, for the low background disturbance level of the free stream (u/U1 < 0.05%), the layer remains laminar to the end of the test section (Rx = 1.4 × 106) and there is no evidence of bursting or other phenomena associated with breakdown to turbulence. A harmonic disturbance is used to excite a sinuous form of instability, which grows over a considerable streamwise distance before breakdown of the streak occurs, which leads to the formation of a turbulent wedge. Detailed measurements show that new streaks are formed on either side during the breakdown process. The characteristics of the wedge are examined over a considerable streamwise distance. A similar mechanism appears to be responsible for the spanwise growth of the wedge since a span-wise succession of new streaks is observed in the early stages of its development.

Résumé :

A series of experimental investigations with a stringent measurement method on the study of the fluid flow behavior for confined compact heat sinks in forced convection have been successfully conducted. In the present study, a theoretical model to effectively predict the velocity and pressure drop for partially-confined heat sinks has been successfully developed. The air velocities flowing into heat sink Us through side bypass U1 and top bypass U2 for various 0.47<H/Hc<1 ratios are evaluated, where H/Hc is the ratio of the heat sink height to channel height. The maximum and average deviations of the velocities predicted by the present model from the experimental data are less than 20.31% and 13.13%, respectively, for confined compact heat sinks. Besides, the results show a good agreement between the predicted results and the experimental data of the pressure drop for the cases of H/Hc = 1. Nevertheless, the relative deviation of the predictions from the experimental data becomes more significant with decreasing H/Hc ratio, i.e., increasing the top bypass of confined compact heat sink. A new modified correlation of pressure drop including the H/Hc effect is presented. The maximum and average deviations of the results predicted by the new correlation from the experimental data are 14.48% and 7.72%, respectively.

Résumé :

Abstract This paper demonstrates a holistic and mechanism-focused approach to select the reservoir with the highest potential for low salinity water (LSW) EOR applied to a carbonate oil field in the UAE. This approach combines fluid-fluid interaction tests and core floods to systematically and cost-effectively cover all potential combinations of high potential reservoir and optimum salinity of LSW. The subject carbonate field is considered to become the first offshore LSW application in UAE. A total of four stock tank oil (STO) samples were collected from three target sub-layers (L1 / L2 / L3) and one reference sub-layer (U1). Brine samples were prepared representing formation water (FW), sea water (SW), and LSW (diluted to 1-20% SW). As the first step, fluid-fluid interaction tests were conducted to select the highest potential target sub-layer for LSW EOR. Micro-dispersion ratios (MDR), which represent water content increment by the oil-water interfacial reaction, were used as the indicator of the reservoir fluid with the most positive EOR potential. During fluid-fluid tests, no micro-dispersion (MD) was formed for FW/SW. MDR increase was observed only for LSW. The MDR comparison revealed STO-L1, L2 and L3 as positive while reference STO-U1 as negative. A clear increase of MDR was found between 2-3% SW for STO-L1 and L2. This indicates that there is a certain threshold salinity triggering the radical oil-water interfacial reaction. The results showed 3-4% SW was the minimum effective SW dilution ratio followed by more effective ratio: 2% SW. Consequently, MDR method enabled us to cost-effectively select the most positive oil STO-L2 and the optimum LSW salinity 1% SW. After selecting the target sub-layer and optimum LSW salinity based on MDR comparison, two core floods (secondary & tertiary modes) were performed using reservoir core. An identical composite reservoir core aged to the original oil wet condition (i.e., core reused after solvent cleaning and re-aged to avoid uncertainties associated with difference in core samples) was used. The result revealed +3%-IOIP recovery by tertiary LSW injection to secondary SW. Re-use of identical core allowed for a quantitative apple-to-apple comparison. The geochemical analysis of effluent (ions: Na+, Ca2+, Mg2+, Cl-, and pH variations) revealed ion-diluting behavior (due to high salinity connate water mixed with LSW) as more pore volume was injected. All the behaviors reaching down to the cut-off concentrations were consistent with a trigger timing of oil recovery profile increase that represented MD formation as evidence of LSW effect. It should be highlighted that this approach was also effectively utilized to quickly screen and evaluate effective additives to LSW to boost the EOR effect. In our case, after confirming that the addition of diethyl ketone (DEK) to LSW doubled MDR compared with pure LSW, core flooding was conducted to reveal significant incremental tertiary recovery of +10%-IOIP after secondary SW flooding.

Résumé :

Abstract Thermal performance of a three chip ball grid array single package technology (SPT) solution has been evaluated under horizontal natural convection condition for under-the-hood automotive applications by solving a conjugate heat transfer problem to determine the maximum junction temperatures as a function of the ambient temperature and the material parameters. The resulting conjugate heat transfer problem is solved using the methods of computational fluid dynamics (CFD). The SPT solution provides packaging of all the die on a single, wire-bonded, plastic ball grid array (PBGA), four layer, BT substrate. All the die are encapsulated in a single mold compound block. The SPT is attached to a 1.52 mm thick, four-layer (with two solid internal copper planes), FR4 printed wiring board (PWB). The multi-dimensional heat transfer effects in the vias and the C5s are taken into account through separate sub-model approach and the effective conductivity is used in the CFD model. The actual stack-ups of the BT substrate and the PWB are used in the CFD analysis. The following die power dissipations are considered: 0.715 W for the one of the dies, U1, 0.3575 W each for the other two dies, U2 and U3. Radiative loss from the exposed surfaces of the package and the PWB to the ambient is included. The following parametric ranges are investigated: ambient temperature: 23, 105 & 125 °C, thermal conductivity of the die attach: 0.5 to 3.7 W/(m K), thermal conductivity of the mold compound: 0.2 to 50 W/(m K), and mold compound and PWB surface emissivities: 0 to 0.8. Since the objective here is the assessment of stand-alone package level thermal performance of the SPT, it is assumed that no other components are dissipating power on the PWB. Transient conjugate problem is also solved for power up of the package initially at an ambient temperature of 125 °C for a power dissipation of 7W. CFD simulations of the transient have been carried out for 7 s after the die is powered up. Based on the results of these analyses, it is concluded that all the three die in the stand-alone SPT operate below a maximum junction temperature of 150 °C for the ranges of parameters investigated. It is noted that the difference between the maximum junction temperature and the ambient temperature decreases with increase in the ambient temperature. The radiative loss to the ambient decreases the maximum junction temperature as much as 3.5 °C, which can be significant in the under-the-hood automotive applications. The maximum junction temperature is nearly independent of the thermal conductivities of the die attach material and the mold compound. It is also shown that the increase in the substrate thermal conductivity (i.e., with increase in the number of vias) reduces the maximum junction temperature significantly — by as much as 10 °C. The maximum junction temperatures become nearly independent of the substrate thermal conductivity for values above 5 W/(m K). The results also show that the temperature distribution of on the surface of the mold compound is very non-uniform and the spreading resistance between the die and the mold compound surface may be a significant portion of the junction to case resistance. For 7 W power dissipation in 125 °C ambient, the die temperature at the end of the transient exceed the maximum allowed (for steady state) temperature of 150 °C. Since this is for a short period of time, it may not pose any reliability problems.
