We find a necessary and sufficient condition for which a point star-configuration in $\mathbb{P}^n$ has generic Hilbert function. More precisely, a point star-configuration in $\mathbb{P}^n$ defined by general forms of degrees $d_1,{\ldots},d_s$ with $3{\leq}n{\leq}s$ has generic Hilbert function if and only if $d_1={\cdots}=d_{s-1}=1$ and $d_s=1,2$. Otherwise, the Hilbert function of a point star-configuration in $\mathbb{P}^n$ is NEVER generic.

This study was performed to investigate the antioxidant effect of Sansa (Crataegi fructus) extract in vitro, and to evaluate the functional effects of Sansa powder addition on the quality properties and storage characteristics of Tteokgalbi. Total polyphenol and flavonoid contents of Sansa extract were found to be 127.00 mg/g and 54.05 mg/g, respectively. The DPPH radical scavenging activity of Sansa extract was high and it was similar to the BHA and BHT. The Tteokgalbi was prepared by 0% (N), 0.1% (S1), 1% (S2), and 2% (S3) of the Sansa Powder. Addition of Sansa powder decreased the protein and lipid contents, but the ash content was significantly increased (p<0.05). Increasing the amount of Sansa powder in the pork Tteokgalbi tended to increase the water holding capacity (WHC) values and the cooking loss (p<0.05). The addition of Sansa powder increased the hardness and chewiness values, but did not affect the cohesiveness and springiness values. In the sensory evaluation, the S3 Tteokgalbi had the best score in color. Values of pH, total microbial counts, thiobarbituric acid (TBA) and volatile basic nitrogen (VBN) values decreased significantly added Sansa powder relative to the normal (p<0.05). The S3 Tteokgalbi was significantly (p<0.05) more effective for delaying lipid peroxidation than the other groups. Sansa powder addition increased the L (lightness) and a (redness) values. Therefore, the results demonstrate that adding the Sansa powder to the pork Tteokgalbi tended to improve antioxidative and antimicrobial effects during the chilled storage period.

Structures of jaw bones, gill rakers and pharyngeal bones of the three Pomadasys species collected from Arafura sea of Indonesia in May 1996 were described and illustrated to compare between species. The percentage of ascending process of premaxillary to head length was 21.6~23.3% in Pomadasys kaakan, 25.4~27.8% in P. maculatus and 15.3~21.0% in P. argyreus. The percentage of ascending process of premaxillary to premaxillary was 54.7~72.8% in P. argyreus, 107.8~114.9% in P. kaakan and 126.7~136.7% in P. maclllatlls. The ascending process of premaxillary of P. argyreus showed a tendency to increase as fish grow. Each jaw in all three grunters had a row of conical teeth exteriorly, but 1 to 5 rows of niddle like teeth interiorly. Among the three species examined, P. maculatus showed the most developed teeth. Pharyngeal bone, appeared to be stronger than jaw teeth, contained dense needle like teeth in P. argyreus, where as that in P. kaakan and P. maculatus had long and slender teeth exteriorly but thicker interiorly. Gill rakers of P. kaakan and P. maculatus are short, but those of P. argyreus are long.

Cultivars or genetic resources with a black seed coat and green cotyledons are rich in lutein, which can promote eye health, and anthocyanin, known for its numerous health benefits. However, mature seeds also contain P34, 7S α' subunit, and lectin proteins, which are allergenic and degrade quality. Here, we report the breeding of a new soybean line with a black seed coat, green cotyledon, and free of P34, 7S α' subunit, and lectin proteins. A total of 157 F₂ seeds with black seed coats and green cotyledons were selected by crossing a female parent with a brown seed coat, green cotyledon, and lacking the 7S α' subunit and lectin proteins with a male parent with a black seed coat, green cotyledon, and lacking the P34 and lectin proteins. The P34 and 7S α' subunit proteins were consistent with a ratio of 9:3:3:1, indicating that they are independent of each other. From 14 F₂ seeds that were recessive (cgy1cgy1p34p34) for both proteins, one individual F₂ plant (F₃ seeds) with the desired traits-black seed coat, green cotyledon, and lacking P34, 7S α' subunit, and lectin proteins- was finally selected. The triple null genotype (absence for P34, 7S α' subunit, and lectin proteins) was confirmed in random F₃ seeds. The selected line has a black seed coat and green cotyledons, and when sown on June 14 in the greenhouse, the maturity date was approximately October 3, the height was about 68 cm, and the 100-seed weight was about 26.5 g.

Let G be a finiteg oroup. We denote BG a classifying space of G, which a contractible universal principal G bundle EG. The stable type of BG does not determine G up to isomorphism. A simple example [due to N. Minami]is given by $Q_{4p} \times Z/2$ and $D_{2p} \times Z/4$ where ps is an odd prime, $Q_{4p} is the generalized quarternion group of order 4p and $D_{2p}$ is the dihedral group of order 2p. However the paper [6] gives us a necessary and sufficient condition for $BG_1$ and $BG_2$ to be stably equivalent localized et pp. The local stable type of BG depends on the conjegacy classes of homomorphisms from the p-groups Q into G. This classification theorem simplifies if G has a normal sylow p-subgroup. Then the stable homotopy type depends on the Weyl group of the sylow p-subgroup.

In this paper we will prove that the groups $D_{p+1}$(2) and $D_{p+1}$(3), where p is an odd prime number, are uniquely determined by their sets of order components. A main consequence of our result is the validity of Thompson's conjecture for the groups $D_{p+1}$(2) and $D_{p+1}$(3).

Porcine epidemic diarrhea virus (PEDV) infection causes acute enteritis with lethal watery diarrhea resulting in a high mortality rate in piglets. As with the other members of group 1 coronaviruses, PEDV also utilizes the host aminopeptidase N (APN) as the major cellular receptor for entry into target cells. The coronavirus spike (S) protein is known to interact with the cellular surface for viral attachment and the S1 domain of all characterized coronaviruses contains a receptor-binding domain (RBD) that mediates a specific high-affinity interaction with their respective cellular receptors. Although the RBDs of several coronaviruses have been mapped, the location of the PEDV RBD has to date not been defined. As a first step toward the identification of the region of the S protein of the PEDV that is critical for recognition with the cellular receptor, we generated a series of S1-truncated variants and examined their abilities to bind to the porcine APN (pAPN) receptor. Our data indicate that the N-terminus of the S1 domain is required for pAPN association. The results from the present study may assist in our understanding of the molecular interactions between the PEDV S protein and the pAPN receptor.
